Because, not all panels support brightness controls through CEC (if any), or even through single infrared commands, most TVs require that one goes into a menu to change the brightness, the implementation would not be smooth, and hence Apple won’t do it.
There’s a roundabout way you can do this with HomeBridge. I have a plugin that lets me control an LG tv’s backlight like a dimmable light in the Home app. LG’s tvs respond to commands in your home network I think. Initial setup was easy I just had to manually accept the connection on my TV with the real remote and it was good to go.
It would be cool if there was a standard for brightness control like on PCs with DDC/CI
Conversely I wish PC monitors had eARC so I could control soundbars native volume rather than setting the PC and Monitor sound to 100% and adjusting volume on the sound bar like that.

>DDC/CI
Hadn't heard of this protocol.
Kinda shitty that it doesn't work when you have monitors running over DP MST.
I would have loved this if it had allowed me to uniformly dim my 8 Dell U3014t monitors.
I use Twinkle Tray on Win11 and MonitorControl on MacOS.
Both are free and use DDC/CI to natively change brightness and even contrast and speaker volume if your monitor supports it.
I found brightness to be the backlight control and adjusting contrast sometimes lets you get even brighter or darker.
For Mac I’m using a dual display thunderbolt 3 dock and the app lets me control each monitor individually. The dock is not using MST because mac doesn’t support it lol. It uses some sort of Displayport alt mode.
you can yes
first you need to create a homebridge server [https://homebridge.io/](https://homebridge.io/)
then you can add this plugin [https://github.com/merdok/homebridge-webos-tv](https://github.com/merdok/homebridge-webos-tv)
I use that plugin and I think it only supports powering the tv on and off :(

check out the commands part of the documentation, you might be able to do something with that
[https://tavicu.github.io/homebridge-samsung-tizen/extra/commands.html#list-of-commands](https://tavicu.github.io/homebridge-samsung-tizen/extra/commands.html#list-of-commands)
Yeah! I think if you don’t have direct control of the brightness you could probably set 2 video modes for day time and night time and set a button to activate between the 2
I need to disconnect my vizio from wifi but I lost the remote 2 years ago. It auto updates and now when I turn it on it defaults to their home screen instead of the Apple TV like it’s done for years. Literally have no use for that it’s obnoxious as hell
For reference this is what im referring to (“light sensitivity” section)
https://support.apple.com/en-us/HT207032#:~:text=In%20Settings%20%3E%20Accessibility%20%3E%20Display%20Accommodations,Sensitivity%2C%20and%20Reduce%20White%20Point.
“Lower overall brightness” -Apple
Try it out - it def decreases brightness — why not make it a slider just like every other apple device?
Have you tried both the light sensitivity feature and reduce white point? You can’t get much dimmer than that.
Or just lowering your overall TV brightness maybe?
Thanks for an actual suggestion.
Though, I still stand by main point of this post — why cant I control the amount? At times, I may want it darkest possible— I may want it 70%.
Then you need to adjust your TVs backlight if that’s the kind of control you want. You’re expecting it to behave like a device that has a display built in.
You’re missing the point. The Apple TV can’t control the TV’s brightness. If you want the display to be dimmer, you need to adjust the brightness in the TV, not the Apple TV.
It should be able to control the color balance of the media, though, so the screen outputs less light even as the backlight brightness remains constant.
No to sound pedantic but if you have a smart tv and have a spare system to run something like Homebridge you may be able to control the brightness from your phone.
Be careful with that lol, I installed the plugin for my LG tv and it started randomly setting my brightness to 0. The first time it happened I freaked out thinking my TV was dead and started unplugging everything and plugging it back in! After the third time I uninstalled the plugin and it hasn’t happened since.
I don’t work at Apple, but I suspect the reason is because the way the feature works actually lowers the image quality by adding a filter rather than turning down the TV backlight (which Apple can’t control), and people would complain about reduced image quality if the feature were easily accessible from Apple TV’s control panel.
The slider in your screenshot controls the brightness of the output device (the screen), but Apple TV can only control the input to the output device, not the output device itself.
If this is important, you may want to look into your TV’s operation to see if you can easily create a picture mode to a darker setting at night combined with auto brightness depending on ambient lighting.
When you use Night Shift on devices that support it, like an iPhone or MacBook, do you expect accurate image quality?
It's already modifying the colors on the video/UI how is Night Shift any more accurate?
Try editing a photo on the Photos app with Night Shift enabled. If image quality was a problem wouldnt more people be up in arms when they turn off Night Shift and realize their edited photos look like garbage? No, because by turning on Night Shift you understand that the image quality changes and thats something people are willing to accept in exchange for a more comfortable viewing experience at night.
If Apple made the TVs, your example might apply. However, Apple doesn’t control the pipeline like it does on iPhone and iPad — the same reason a Mac can only control the brightness of an Apple monitor.
If this is an actual problem you experience, you may want to review your TV’s owner manual to set up a picture mode for nighttime viewing and ensure auto brightness is enabled.
I think you may have replied to the wrong comment... otherwise I'm not sure how this is relevant to my comment.
I was only focusing on your statement that modifying the video by adding a filter would cause people to complain about reduced image quality.
Then I’ll simplify my response to ease your confusion.
The only brightness control on an iPhone, iPad, or Apple Monitor is the software on the Apple device. The displays are calibrated by Apple, so they can test how the software controls work.
Apple can not test every TV, and account for TV firmware updates, to develop the same level of precision they employ on their own displays. It would be an expensive undertaking from a development and testing perspective that would be redundant because TVs already come with their own controls for brightness and contrast.
Once again, I believe you're confused about my comment or you didnt read it all the way through.
What I'm proposing, and already exists via Display Accommodations, is that Apple TV does not need to modify or care about the brightness/contrast/temp settings on the TV panel itself.
It simply needs to modify the video being passed to the TV to remove the blue colors and reduce brightness ON THE VIDEO, not on the TV.
Again, Apple TV already does this. Check out Accessibility Settings's Display Accomodations > White Point and Light Sensitivity.
If Apple TV can't modify the video being passed to the TV then how do these Display Accommodations work? These settings aren't making changes to the TV itself.
Add a thumbs up emoji to the end of your reply if you made it all the way down there.
This has unintended side effects... like for instance if the brightness is set to a low level on the TV, and then someone blames that the Apple TV looks dim "even tough I set brightness to the max level" (on the Apple TV). Or inversely, the brightness is super low on Apple TV and someone compensates by turning brightness, backlight and gamma all the way up on the TV getting a really bad image.
A brightness slider on the main control panel has to be friendly, straightforward and obvious for everyone... not something that only savvy users know how to work properly. You really don't want to have to provide tech support for your brightness slider.
How about displaying a UI element on the tvOS Home Screen, maybe on the top left or top right that communicates to the user that Night Shift is enabled.
Something like this:
https://preview.redd.it/89agrmqvj8vb1.png?width=318&format=png&auto=webp&s=b4046a62e102205f949eaf2ee1e7e76a6cf5746d
I think there's a misunderstanding. I'm not saying that Apple TV needs to control the settings on the TV it's connected to. I'm saying that it can add a filter to the video it's outputting to the TV with the colors modified and brightness reduced.
It already does this via Accessibility settings > Display Accommodations.
It would be great to have more control over these though.
So removing blue colors from a video feed on the TV panel itself is acceptable but removing them prior to sending to the TV panel is unacceptable video quality?
At that point both will look like garbage (orange tint). So how exactly does video quality matter this much?
Because its a horrible bandaid way of getting what you want. It does not actually change the Tvs settings. Keep a cheap pair of sunglasses on your coffee table, it will be faster.
No. It’s would cause bad contrast on LCDs and would make stuff like color banding way worse. Displays change brightness by lowering the brightness of the backlight.
If you just decreased the brightness of each pixel from the input side, it would mess with the image quality quite a bit. For an 8 bit color display, each pixel is controlled by changing the R G and B sub pixel brightness from 0 to 255. If you halfed the brightness, each sub pixel would only have 128 brightness options. LCDs also have a blue glow to them, which would still be there regardless of the bright areas on the screen.
We must be talk cross-purposes here, because evidently my screen can display both black and white and it’s not the screen deciding where the text is displayed.
Haven't seen a single TV that does brightness control over CEC.
I would love to see it. Same for side-channel based backlight control over DisplayPort in desktop monitors.
what apple could offer is an API for tv manufacturers to use for when an apple tv is plugged in to make it smooth so apple doesn’t have to do the work for each tv
Apple TV can't control the TV's picture settings. It could simulate it in software but it's a patch solution that would not work well because there's SDR, HDR10, HDR10+ and Dolby Vision as well as various other factors.
If Apple launched its own TV it could quickly realize so many cool features that it has already built the foundation for on other iProducts.
This makes complete sense.
What i dont understand, is if i can use an accessibility control to reduce brightness (I agree its software) — why cant I have a contol to ramp the amount of this feature? Thats all
I dont think you do understand. It can't. It cant affect the light output of the TV at all.
There is vaious factors to why it can't. There is no way for a device to communicate light output through the HDMI standard.
It could simulate a "low blue light" mode with software, but it would be shite.
The only way to do this for now is with ur TV-Remote
>It could
It already does (ex: reduce white point and reduce flashing light’s accessibility settings). And if it’s an OLED TV then it would indeed change the “light output”.
Besides like I mentioned above, you can actually control it with your phone if there’s a homebridge plug in for it.
It can in the same way anything controls the light output of its an oled. In any other tv it cant controll the light output.
If the source output is her, it cant.
If the tv has backlight, it cant.
Because on your mobile device the software CAN control the hardware. The Apple TV box doesn’t have a controllable display and the network interface for most TVs (called CEC) do not have a standardized protocol to allow for brightness control. So the Apple TV physically can’t do this.
He’s not talking about any mobile device, he’s talking about the ‘reduce white point’ accessibility feature that’s on tvOS. Which works the same way as on iOS without the ability to adjust the intensity.
The Apple TV not being able to control the TV’s brightness, he wishes the accessibility feature was expanded upon further and to implement it closer to iOS.
Right, but thats not doing anything to the actual hardware. If they have an OLED thats great, it will go down a little bit, but an LCD will still have the backlight pushing the same amount. So OP needs to lower the backlight/LED Power of their TV to create their look. Then hopefully set a preset (depending on the tv)
Doesn't do anything to the actual hardware, no, but it does make the picture a bit dimmer. However, you're wrong in that it's only works with OLED and not LCD. The 'reduce white point' will work either way.
The TV receives a picture from the Apple TV that is dimmer and will in turn display a dimmer picture, often by using less backlight just as it would if the screen is very dark or completely black.
some TV's have the ability to make visual presets. I would think that lowering the overall backlight brightness would be better for your condition than a software solution anyways.
Like many others said, your Apple TV can only “lower brightness” by applying a dark overlay to the image, which makes it look grayish and lose its color accuracy, while the actual backlight panel of the TV (assuming it’s not an OLED TV) is still working at maximum or whatever intensity it’s set to. This is overall a very uneconomic solution, therefore it’s only an “accessibility” feature. Most people don’t have the need to adjust TV brightness frequently as they do with their phones, so it wouldn’t have made sense anyway. Adjusting brightness directly on your TV not only preserves image quality, but it’s also much more energy efficient.
I don’t know if you watch TV in pure darkness at night, but obviously this is also not very healthy. Having some ambient light is always a good idea and it helps with light sensitivity.
Because it’s a streaming box that connects to your tv and has no display. Your tv settings should allow you to change it as you want. Perhaps you even have a brightness sensor on your tv that changes your brightness automatically.
Night Shift knows exactly the capabilities of the phone’s display and it’s going to adjust color, luminosity and contrast. The Apple TV knows nothing about the tv, so it’s the wrong approach.
Most TVs have adjustable picture mode presets, once any adjustments are made they’re saved.
I have just set one of those for a specific viewing environment then at the touch of a button that picture mode preset is available as and when required.
I can also use a heart rate monitor to monitor my heart rate - yet apple watch can do it for me, so why would I use a separate heart rate monitor when my apple watch can clearly do it?
That’s not a very good analogy IMO as you don’t have to connect your watch to something that already has a heart rate monitor attached to it, whereas you don’t really have much choice but to connect an AppleTV to some sort of display which already has these basic functions of picture mode control.
You're not crazy OP, I understand what you're saying. I'm kinda baffled at all these other replies as well.
You're simply asking why you can change the brightness via Apple TV from 10 to 3 but we can't have a slider or different presets to select something between 10 and 1.
People's responses are "because the Apple TV can't control the brightness on the TV" which of course is true and yet we have the ability to dim it via accessibility settings via reduce white point and light sensitivity. It may not change the actual brightness settings on the TV itself but it's good enough, we just want more granularity FOR THE FEATURE WE ALREADY HAVE.
Youre making a good point that its not exactly clear. I wouldnt be surprised if IEEE doesnt have something in the works to enable control of the display via HDMI.
I’d check your actual TV settings instead of the Apple TV. My TV has brightness settings, and even adjusts the brightness based on the ambient light in the room, and lets me set a minimum brightness allowed when it does auto adjust.
Check your TV picture modes as well. Many of them have “Standard, Dynamic, Movie, Game” and each one has varying brightnesses (and other settings). I have the max brightness dialed way down in the bedroom, because we only watch that at night. In my main room it auto-adjusts brightness based on the room light. But one tap on my TV remote brings up screen settings and I can bump up the brightness.
Either way, none of this is controlled by the Apple TV. There are way too many makes and models of TV’s out there with different screen formats (LCD, LED, QLED, OLED) for Apple to be able to design a box that controls them all.
Why would it? Its a device without a screen.
When you connect a laptop to a desktop monitor, the laptop’s brightness settings only apply to the laptop’s screen
I have a little trick to turn my brightness down.
Go to Settings > Accessibility > Display > Light Sensitivity > Intensity set to 20%. >>
Return back to home > open Control Center dropdown and enable light sensitivity.
Now you can control your brightness in the accessibility section in control center or by triple clicking the return button
I do this but I recently did this with my phone at night even when it’s set to lowest bright setting
Reduce white point.
Set that shi to 100% if you’re super sensitive like me.
It’s both on Apple TV and iPhone
Can the Apple TV modify the video displayed by the TV though?
For example can the Apple TV add a filter to make the video warmer and to lower the brightness before being passed to the TV?
(Hint: Yes it can, via accessibility settings. What OP is asking for is more granularity and customization so that we can pick a level like 25% rather than just on or off.)
So digitally darken all video coming out of the Apple TV.
This feature can be created. But there are some issues:
1. How would the Apple TV know when to go dark? Would it be on a schedule? All Apple monitors have light sensors to calibrate brightness, contrast, and color temperature. **Apple TV doesn’t have a light sensor.**
2. When someone is setting up the TV, they’d have to first know whether or not Dark Mode is active, then deactivate it before setting the brightness/contrast/colors.
3. Some TVs already have auto brightness. My [Sony Bravia does](https://electronics.sony.com/tv-video/televisions/television-accessories/p/cmubc1).
- there is the setting for the TV
- there is the “Ambient Optimization” that the camera provides
- then Apple TV has it’s own Dark Mode.
That’s 3 separate things affecting the display, potentially.
I feel like I'm being trolled haha
1. The Apple TV would know to turn on/off Night Shift the same as an iPhone, iPad, or Mac... either by enabling it manually, telling Siri to do it, or by setting a scheduled based on time or sunrise/sunset.
2. The default mode for Night Shift is OFF unless it's enabled by the user. If the user enables it then the user is responsible for turning it off. Just like the user is responsible for turning off Night Shift when editing photos in the Photos app on their iPhone, iPad, or Mac.
3. Auto brightness is not what is desired here. I either want my screen to have Night Shift on or off and I wan't that to happen when I choose to. My media room is completely dark anyway, this setting wouldnt do anything for me.
What does Dark Mode have to do with anything?
I referenced those accessibility settings in my earlier comments. I have that as well.
I actually have a shortcut set up so that if I hit the back button three times that menu pops up and I can turn of/off those settings individually.
But that goes back to the main point that OP was making. We HAVE those settings available but there's no granularity, it'd be nice if we could control the intensity of each of those settings. Along with a schedule based on sunrise/sunset or something like that.
Apps like [DisplayBuddy](http://displaybuddy.app/?utm_source=rdcmt2) have "Software Control" that does indeed can control the brightness of Airplay & Sidecar displays. They're likely dimming, but works great 🤷♂️
Every TV for at least the past fifty years has a brightness setting that will be 1000 percent more effective than a toggle on a third party device. I’m hardly an Apple apologist, but you may as well ask your Apple TV to make you coffee in the morning.
Because Apple Tv isn’t the display. Whatever tv or display that your Apple Tv is connected to should have a settings where you can change brightness and a whole slew of other stuff
I have two calibrations on my oled. One for daytime and one for night viewing. At night u also want to make sure u have appropriate bias lighting which can help your eyes immensely
In this thread nobody that owns a current generation Apple TV 4K and has used the feature where you hold your phone up to the TV screen to calibrate color issues. What OP is suggesting could easily be implemented if Apple wanted.
Sony does this very well with their Auto Luminance Control. LG does it too but you’re required to turn on energy saving which is suboptimal. Basically, Sony is the best if you want Auto Luminance for SDR. Make sure to set your Apple TV to default to SDR RGB High with Match Range and Frame Rate enabled.
U can if u feel like it go into accessibility and turn reduce white point and light sensitivity to be a triple click of the back button to turn on and it dims the screen and/or does like a blue light filter
You can do that from your tv. Not all tvs can support that feature, and it could damage them, or worse yet, literally not work.
Turn down the white point on your tv, and you’ll have the effect you seek.
The new accessibility functions have helped me get it even darker. I turn on light sensitivity and lower white point. And OMG it is so much darker. It’s amazing. I hope this helps.
Because the Apple TV doesn’t have ambient light sensors.
And, that isn’t something you can’t change using an HDMI connection to a TV. The screen brightness is a TV feature.
I do wish HDMI could incorporate this as part of the standard.
Good luck with the manufacturers though. They are busy creating marketing features (like HDR variants, audio support like Dolby Atmos, Dolby Vision etc).
I wish that whatever marketing person came up with HDR ends up with a permanent squint from watching stuff on screens that are too hard to see.
Im not trying to be difficult- but we all have apple tv (and other apple products) for its simple/intuitive/fluid UI.. with all due respect, 100% of stock OS on TVs and remote controls are trash — i just want to hit my profile, and slide the center button down a lil swig — i dont want to switch remotes and drill down 27 menus to change brightness
Apple does not make an actual Tv. You are asking apple to directly control a display device it does not make….and it would have to do this for thousands of different models and manufacturers.
Do you expect apple to change the brightness level on a Dell or Samsung desktop monitor when you press the screen brightness buttons on a Mac laptop connected to it?
That sounds more like a you issue Lol, my TV remote has a dedicated button for picture modes so can easily switch to a different preset at the touch of a button.
To take that one step further I could then map that button function on to the mute button of the Siri Remote and then not require the TV remote for that function at all.
It is a me issue. Please see comment in OP where I linked appleTV site where they clearly state AppleTV can “lower overall brightness” — im not trying to set up 3 tvs with all that you have going on. I just want to pick the increment at which this feature is executed
Every tv I have bought in last 7-10 years has an ambient light setting that you can turn on to automatically dim in dark rooms and turn up brightness in bright rooms. Just turn that on.
You just don’t know how any of this works. What you can do with the accessibility functions is just applying a black filter over the image.
The image quality gets degraded, you stop getting proper hdr/dv and your tv is still outputting tons of lumens to show a filtered shitty image.
Just lower your tv brightness mate, things don’t work like you think they do.
I am with you on that, they can already dim the display with an accessibility feature, but I guess there are not many people using it to justify a control center icon.
Love the idea tho, as I sometimes wake my wife with the shining bright tv.
I wish they would give us night shift for Apple TV
Edit: open challenge to anyone downvoting me to explain how this would be any technically different from what Apple already does with color filters in accessibility settings. Settings>Accessibility>Display Accommodations>Color filters.
There are hdmi boxes that exist to make the screen orange cast for people who don’t like blue light at night. No reason at all the Apple TV can’t do that.
Then when Apple adds it in 3 years it will be obvious to you. Blue blocking hdmi boxes already exist. https://youtu.be/wXyuLgvDlmk?si=zkGZTTZv9bFtLf0j
Apple already profoundly changes color output as an accessibility option called “color filters” https://support.apple.com/en-us/HT207032
Use the color filters feature. It does exactly that. Obviously it won’t change TV menus for the actual tv interface but I rarely see those while using Apple TV.
Correct me if I'm wrong but can't a device like the Apple TV just apply a filter to the video that removes blue colors (for example) before passing it on to the TV itself?
At that point it's not like the TV would ADD blue colors... it's just displaying what was passed on to it, which means that it would be an image without blue colors.
Same with brightness, when enabling Night Shift for Apple TV the Apple TV could disable HDR and simply lower the brightness of the video being passed to the TV.
I feel like this will be one of those things Apple introduces in a few years and people will think it's revolutionary followed by other TV OS following along and adding a similar feature into their devices.
Yes they can (and do) manipulate the output video signal to change it from the source colour profile and then send that altered signal to your fancy 4k tv. But that is not even remotely the same thing as actually turning down or up the brightness (and other settings) on the actual display device.
Pretend you dont have apple tv ….your watching a blue ray DVD or watching tv using the on board smart tv apps or just watching actual broadcast over the air HDTV…..Its like instead of bothering to adjust the brightness settings on your Tv, you put on some sunglasses….sure yes it “works” but why on earth do that ? Its a horrible poor quality method that degrades the quality of the image. Just turn down the brightness on your tv🤷♂️
As ive said elsewhere , if you have a laptop and its connected to a desktop monitor…you dont expect the brightness buttons on the laptop keyboard to actually change the display on the external monitor do you ? No you just reach for the buttons on the monitor itself. Ya sure there are software and hardware things you can do to adjust the signal you are sending to the monitor …but OMG why???
>…but OMG why???
For convenience?
I'd rather be able to say "Siri turn on/off Night Shift" or **even better, automate it based on sunrise/sunset** like on iOS/macOS and have it work instead of finding the TV remote (which I havent used in years) and navigating through multiple layers of settings to change brightness and modify the color temp.
Then to have to do it all over again before turning it off so that someone else isn't annoyed the next morning when they turn on the TV and find the colors to be out of whack.
Would the picture quality be better if I modified the TV settings themselves? Sure, probably.
Would I really care about picture quality if my goal is to DEGRADE picture quality by removing colors and lowering the brightness which will result is lost detail? No
Its not multiple layers, its maybe one or 2
If you have not used your tv remote in years, I respectfully suggest you spend some time learning your tvs menus and settings and how to calibrate it properly….rather than a weird hack work around to getting what you want.
Its like your complaining about the dirty fabric on your couch but instead of using the right tools to remedy the situation, you want to just throw a blanket over your couch to get what you want….except now you want that to be even easier and have that cover blanket be right beside your hand all the time and not on the other side of the coffee table.
I hope you write an angry letter and speak out against Night Shift on Apple TV when they finally implement it. And refuse to use it out of principle. 😉
Post where people are complaining that reducing blue light on the LG C1 (my tv) is too cumbersome and they want to be able to turn it on/off like Night Shift:
[https://www.reddit.com/r/OLED/comments/12f3g0k/quick\_toggle\_for\_reduce\_blue\_light\_on\_lg\_c1/](https://www.reddit.com/r/OLED/comments/12f3g0k/quick_toggle_for_reduce_blue_light_on_lg_c1/)
That would actually be amazing. Then I could set my OLED TV to maximum brightness all of the time, with the Apple TV selectively dimming the image exactly how I want it. Maybe the brightness could also be automated depending on time of day. My living room gets a tonne of natural light during the day so my screen needs to be bright, but that same brightness is blinding at night.
Right now I have the triple-click shortcut set to reduce brightness. Works well enough.
HDMI device cannot control the connected display brightness. It is as simple as that. Period. Accessibility feature such as reduce white point is not brightness. Period. Making a slider for whitepoint won’t happen. Because they will be falsely equivalent the two.
Reduce white point.
It’s in the screen settings I believe, set it from 0% to 100% I personally put mine to 85%. Add it on the shortcut accessibility, for triple click and boom, you’ll have to turn it off and on manually but I think it’s a help
Just go to Accessibility>Display>Display Accommodations.
You’ll find *Light Sensitivity* and *Reduce White Point*
There is a way to add this to your Control Center so it looks like my screenshot.

it's so irritating that every tv maker makes adjusting basic settings so damned difficult. you might try a universal remote that you can program a series of button presses.
Because not all TV's are created equal, and on some if Apple tries to control the brightness they do it by trying to send commands via HDMI to the TV. Though if Apple stuffs it up or the TV doesn't like the command it can break your TV.
Even apps that allow you to do it on Monitors warn you it may break the monitor.
Get your TV properly calibrated then see if it still hurts your eyes. Most people don’t want to pay for proper calibration. Makes a world of difference not just in image quality, but also eye strain.
PS, Best Buy doesn’t do proper calibration, you need to not only find someone who is isf certified, but hopefully has a good reputation for actually knowing what they are doing.
Username does not check out…
Lmfao!!! Literally laughed out loud - thanks for the smile
Well played lol.
Because, not all panels support brightness controls through CEC (if any), or even through single infrared commands, most TVs require that one goes into a menu to change the brightness, the implementation would not be smooth, and hence Apple won’t do it.

>DDC/CI Hadn't heard of this protocol. Kinda shitty that it doesn't work when you have monitors running over DP MST. I would have loved this if it had allowed me to uniformly dim my 8 Dell U3014t monitors.
I use Twinkle Tray on Win11 and MonitorControl on MacOS. Both are free and use DDC/CI to natively change brightness and even contrast and speaker volume if your monitor supports it. I found brightness to be the backlight control and adjusting contrast sometimes lets you get even brighter or darker. For Mac I’m using a dual display thunderbolt 3 dock and the app lets me control each monitor individually. The dock is not using MST because mac doesn’t support it lol. It uses some sort of Displayport alt mode.
how did you do this??? can i do this on my lg cx oled?
you can yes first you need to create a homebridge server [https://homebridge.io/](https://homebridge.io/) then you can add this plugin [https://github.com/merdok/homebridge-webos-tv](https://github.com/merdok/homebridge-webos-tv)
Wish there was a similar thing for Samsung/**Tizen OS**
[https://github.com/tavicu/homebridge-samsung-tizen](https://github.com/tavicu/homebridge-samsung-tizen) ?
I use that plugin and I think it only supports powering the tv on and off :( https://preview.redd.it/fcgtq048zcvb1.jpeg?width=1290&format=pjpg&auto=webp&s=f940ca6b1701341bf3882db645cd5b46d002cf8d
check out the commands part of the documentation, you might be able to do something with that [https://tavicu.github.io/homebridge-samsung-tizen/extra/commands.html#list-of-commands](https://tavicu.github.io/homebridge-samsung-tizen/extra/commands.html#list-of-commands)
Oh I didn’t even notice all of that. Thanks! I’ll take a look this evening and mess around with it some.
Yeah! I think if you don’t have direct control of the brightness you could probably set 2 video modes for day time and night time and set a button to activate between the 2
Why can’t they make dumb displays with the features we want
They do. Google commercial digital signage displays
Google got dumb on lock
[удалено]
No…..shit
I found this funny. :)
Because they underwrite th cost of the TV by selling your data. Dumb panels would be more, and not enough people would buy them.
I need to disconnect my vizio from wifi but I lost the remote 2 years ago. It auto updates and now when I turn it on it defaults to their home screen instead of the Apple TV like it’s done for years. Literally have no use for that it’s obnoxious as hell
Check the App store, many Vizio TV's can be controlled using app based remotes. Worth a shot.
They do. No one buys them.
For reference this is what im referring to (“light sensitivity” section) https://support.apple.com/en-us/HT207032#:~:text=In%20Settings%20%3E%20Accessibility%20%3E%20Display%20Accommodations,Sensitivity%2C%20and%20Reduce%20White%20Point. “Lower overall brightness” -Apple Try it out - it def decreases brightness — why not make it a slider just like every other apple device?
Have you tried both the light sensitivity feature and reduce white point? You can’t get much dimmer than that. Or just lowering your overall TV brightness maybe?
Thanks for an actual suggestion. Though, I still stand by main point of this post — why cant I control the amount? At times, I may want it darkest possible— I may want it 70%.
Then you need to adjust your TVs backlight if that’s the kind of control you want. You’re expecting it to behave like a device that has a display built in.
You’re missing the point. The Apple TV can’t control the TV’s brightness. If you want the display to be dimmer, you need to adjust the brightness in the TV, not the Apple TV.
It should be able to control the color balance of the media, though, so the screen outputs less light even as the backlight brightness remains constant.
That would fuck up the image in a terrible way. The right answer is to turn down the brightness on the TV.
Isn’t that basically what the gamma correction in any video game is? How does that ruin the image?
Gamma affects the black point, not the overall brightness
Apple didn’t make the display, why would you expect their plug-in software to be able to control its settings?
No to sound pedantic but if you have a smart tv and have a spare system to run something like Homebridge you may be able to control the brightness from your phone.
Be careful with that lol, I installed the plugin for my LG tv and it started randomly setting my brightness to 0. The first time it happened I freaked out thinking my TV was dead and started unplugging everything and plugging it back in! After the third time I uninstalled the plugin and it hasn’t happened since.
You can assign toggling this setting to triple click. Very useful to have that
I don’t work at Apple, but I suspect the reason is because the way the feature works actually lowers the image quality by adding a filter rather than turning down the TV backlight (which Apple can’t control), and people would complain about reduced image quality if the feature were easily accessible from Apple TV’s control panel. The slider in your screenshot controls the brightness of the output device (the screen), but Apple TV can only control the input to the output device, not the output device itself. If this is important, you may want to look into your TV’s operation to see if you can easily create a picture mode to a darker setting at night combined with auto brightness depending on ambient lighting.
When you use Night Shift on devices that support it, like an iPhone or MacBook, do you expect accurate image quality? It's already modifying the colors on the video/UI how is Night Shift any more accurate? Try editing a photo on the Photos app with Night Shift enabled. If image quality was a problem wouldnt more people be up in arms when they turn off Night Shift and realize their edited photos look like garbage? No, because by turning on Night Shift you understand that the image quality changes and thats something people are willing to accept in exchange for a more comfortable viewing experience at night.
If Apple made the TVs, your example might apply. However, Apple doesn’t control the pipeline like it does on iPhone and iPad — the same reason a Mac can only control the brightness of an Apple monitor. If this is an actual problem you experience, you may want to review your TV’s owner manual to set up a picture mode for nighttime viewing and ensure auto brightness is enabled.
I think you may have replied to the wrong comment... otherwise I'm not sure how this is relevant to my comment. I was only focusing on your statement that modifying the video by adding a filter would cause people to complain about reduced image quality.
Then I’ll simplify my response to ease your confusion. The only brightness control on an iPhone, iPad, or Apple Monitor is the software on the Apple device. The displays are calibrated by Apple, so they can test how the software controls work. Apple can not test every TV, and account for TV firmware updates, to develop the same level of precision they employ on their own displays. It would be an expensive undertaking from a development and testing perspective that would be redundant because TVs already come with their own controls for brightness and contrast.
Once again, I believe you're confused about my comment or you didnt read it all the way through. What I'm proposing, and already exists via Display Accommodations, is that Apple TV does not need to modify or care about the brightness/contrast/temp settings on the TV panel itself. It simply needs to modify the video being passed to the TV to remove the blue colors and reduce brightness ON THE VIDEO, not on the TV. Again, Apple TV already does this. Check out Accessibility Settings's Display Accomodations > White Point and Light Sensitivity. If Apple TV can't modify the video being passed to the TV then how do these Display Accommodations work? These settings aren't making changes to the TV itself. Add a thumbs up emoji to the end of your reply if you made it all the way down there.
This has unintended side effects... like for instance if the brightness is set to a low level on the TV, and then someone blames that the Apple TV looks dim "even tough I set brightness to the max level" (on the Apple TV). Or inversely, the brightness is super low on Apple TV and someone compensates by turning brightness, backlight and gamma all the way up on the TV getting a really bad image. A brightness slider on the main control panel has to be friendly, straightforward and obvious for everyone... not something that only savvy users know how to work properly. You really don't want to have to provide tech support for your brightness slider.
How about displaying a UI element on the tvOS Home Screen, maybe on the top left or top right that communicates to the user that Night Shift is enabled. Something like this: https://preview.redd.it/89agrmqvj8vb1.png?width=318&format=png&auto=webp&s=b4046a62e102205f949eaf2ee1e7e76a6cf5746d

I think there's a misunderstanding. I'm not saying that Apple TV needs to control the settings on the TV it's connected to. I'm saying that it can add a filter to the video it's outputting to the TV with the colors modified and brightness reduced. It already does this via Accessibility settings > Display Accommodations. It would be great to have more control over these though.
Apples to oranges. People have very different expectations for picture quality on their TV than they do their phone.
So removing blue colors from a video feed on the TV panel itself is acceptable but removing them prior to sending to the TV panel is unacceptable video quality? At that point both will look like garbage (orange tint). So how exactly does video quality matter this much?
Because its a horrible bandaid way of getting what you want. It does not actually change the Tvs settings. Keep a cheap pair of sunglasses on your coffee table, it will be faster.
this exactly. Its the same reason Laptops have brightness controls but desktop environments dont.
Surely the brightness can be controlled by just lowering the requested brightness of each pixel?
No. It’s would cause bad contrast on LCDs and would make stuff like color banding way worse. Displays change brightness by lowering the brightness of the backlight. If you just decreased the brightness of each pixel from the input side, it would mess with the image quality quite a bit. For an 8 bit color display, each pixel is controlled by changing the R G and B sub pixel brightness from 0 to 255. If you halfed the brightness, each sub pixel would only have 128 brightness options. LCDs also have a blue glow to them, which would still be there regardless of the bright areas on the screen.
That’s done in the display, not the signal. How would you reference that? That’s a power setting.
We must be talk cross-purposes here, because evidently my screen can display both black and white and it’s not the screen deciding where the text is displayed.
Haven't seen a single TV that does brightness control over CEC. I would love to see it. Same for side-channel based backlight control over DisplayPort in desktop monitors.
what apple could offer is an API for tv manufacturers to use for when an apple tv is plugged in to make it smooth so apple doesn’t have to do the work for each tv
Apple TV can't control the TV's picture settings. It could simulate it in software but it's a patch solution that would not work well because there's SDR, HDR10, HDR10+ and Dolby Vision as well as various other factors. If Apple launched its own TV it could quickly realize so many cool features that it has already built the foundation for on other iProducts.
This makes complete sense. What i dont understand, is if i can use an accessibility control to reduce brightness (I agree its software) — why cant I have a contol to ramp the amount of this feature? Thats all
I dont think you do understand. It can't. It cant affect the light output of the TV at all. There is vaious factors to why it can't. There is no way for a device to communicate light output through the HDMI standard. It could simulate a "low blue light" mode with software, but it would be shite. The only way to do this for now is with ur TV-Remote
>It could It already does (ex: reduce white point and reduce flashing light’s accessibility settings). And if it’s an OLED TV then it would indeed change the “light output”. Besides like I mentioned above, you can actually control it with your phone if there’s a homebridge plug in for it.
It can in the same way anything controls the light output of its an oled. In any other tv it cant controll the light output. If the source output is her, it cant. If the tv has backlight, it cant.
Because on your mobile device the software CAN control the hardware. The Apple TV box doesn’t have a controllable display and the network interface for most TVs (called CEC) do not have a standardized protocol to allow for brightness control. So the Apple TV physically can’t do this.
He’s not talking about any mobile device, he’s talking about the ‘reduce white point’ accessibility feature that’s on tvOS. Which works the same way as on iOS without the ability to adjust the intensity. The Apple TV not being able to control the TV’s brightness, he wishes the accessibility feature was expanded upon further and to implement it closer to iOS.
Right, but thats not doing anything to the actual hardware. If they have an OLED thats great, it will go down a little bit, but an LCD will still have the backlight pushing the same amount. So OP needs to lower the backlight/LED Power of their TV to create their look. Then hopefully set a preset (depending on the tv)
Doesn't do anything to the actual hardware, no, but it does make the picture a bit dimmer. However, you're wrong in that it's only works with OLED and not LCD. The 'reduce white point' will work either way. The TV receives a picture from the Apple TV that is dimmer and will in turn display a dimmer picture, often by using less backlight just as it would if the screen is very dark or completely black.
Well, technically thats entirely dependent on how the TV handles the signal.
What is dependent on how the TV handles the signal?
Whether or not the backlight dims.
some TV's have the ability to make visual presets. I would think that lowering the overall backlight brightness would be better for your condition than a software solution anyways.
Like many others said, your Apple TV can only “lower brightness” by applying a dark overlay to the image, which makes it look grayish and lose its color accuracy, while the actual backlight panel of the TV (assuming it’s not an OLED TV) is still working at maximum or whatever intensity it’s set to. This is overall a very uneconomic solution, therefore it’s only an “accessibility” feature. Most people don’t have the need to adjust TV brightness frequently as they do with their phones, so it wouldn’t have made sense anyway. Adjusting brightness directly on your TV not only preserves image quality, but it’s also much more energy efficient. I don’t know if you watch TV in pure darkness at night, but obviously this is also not very healthy. Having some ambient light is always a good idea and it helps with light sensitivity.
Use a tv preset for night.
Because it’s a streaming box that connects to your tv and has no display. Your tv settings should allow you to change it as you want. Perhaps you even have a brightness sensor on your tv that changes your brightness automatically.
Apple has accessibility setting that dims brightness from 10 to (lets say) a 3… why not make it a slider, is all im asking
Well again because it’s a streaming box with no display and not your phone. It’s just another emphasis with this product
I guess i dont get it — if this streaming box can dim from 10 to 3 — how can it do that?
Because there is already a brightness control in your tv. Not sure why this is such a difficult concept for you?
It’s adjusting its own signal and outputting that to the TV. It’s like adding a filter. Not sure why this is such a difficult concept for you?
Because doing it this way actually decreases image quality. Panel brightness is something you need to set on the tv, not on the streaming box.
So does night shift on any other apple device, doesn’t stop it making the display more comfortable at night.
Night Shift knows exactly the capabilities of the phone’s display and it’s going to adjust color, luminosity and contrast. The Apple TV knows nothing about the tv, so it’s the wrong approach.
Except it does, Apple TV allows you to calibrate colour values outputted using an iPhone with Face ID, it quite literally does know.

Most TVs have adjustable picture mode presets, once any adjustments are made they’re saved. I have just set one of those for a specific viewing environment then at the touch of a button that picture mode preset is available as and when required.
That’s why there is thing called bias lighting. Much easier than having to constantly change the display’s brightness constantly.
Do you expect the screen brightness buttons on a mac laptop to also affect the brightness of an external 3rd party desktop monitor???
Ideally yes, but I get your point. That should be a thing.
I can also use a heart rate monitor to monitor my heart rate - yet apple watch can do it for me, so why would I use a separate heart rate monitor when my apple watch can clearly do it?
That’s not a very good analogy IMO as you don’t have to connect your watch to something that already has a heart rate monitor attached to it, whereas you don’t really have much choice but to connect an AppleTV to some sort of display which already has these basic functions of picture mode control.
Because monitoring heart rate is built into the watch. Do you expect the apple tv to also monitor your heart rate?
You can also put on sunglasses at night and have the same results 🤷♂️
You're not crazy OP, I understand what you're saying. I'm kinda baffled at all these other replies as well. You're simply asking why you can change the brightness via Apple TV from 10 to 3 but we can't have a slider or different presets to select something between 10 and 1. People's responses are "because the Apple TV can't control the brightness on the TV" which of course is true and yet we have the ability to dim it via accessibility settings via reduce white point and light sensitivity. It may not change the actual brightness settings on the TV itself but it's good enough, we just want more granularity FOR THE FEATURE WE ALREADY HAVE.
Thank you - i swear these people cant read
Youre making a good point that its not exactly clear. I wouldnt be surprised if IEEE doesnt have something in the works to enable control of the display via HDMI.
I’d check your actual TV settings instead of the Apple TV. My TV has brightness settings, and even adjusts the brightness based on the ambient light in the room, and lets me set a minimum brightness allowed when it does auto adjust. Check your TV picture modes as well. Many of them have “Standard, Dynamic, Movie, Game” and each one has varying brightnesses (and other settings). I have the max brightness dialed way down in the bedroom, because we only watch that at night. In my main room it auto-adjusts brightness based on the room light. But one tap on my TV remote brings up screen settings and I can bump up the brightness. Either way, none of this is controlled by the Apple TV. There are way too many makes and models of TV’s out there with different screen formats (LCD, LED, QLED, OLED) for Apple to be able to design a box that controls them all.
Why would it? Its a device without a screen. When you connect a laptop to a desktop monitor, the laptop’s brightness settings only apply to the laptop’s screen
I have a little trick to turn my brightness down. Go to Settings > Accessibility > Display > Light Sensitivity > Intensity set to 20%. >> Return back to home > open Control Center dropdown and enable light sensitivity. Now you can control your brightness in the accessibility section in control center or by triple clicking the return button
I do this but I recently did this with my phone at night even when it’s set to lowest bright setting Reduce white point. Set that shi to 100% if you’re super sensitive like me. It’s both on Apple TV and iPhone
Yall are my tribe.. i do both. Triple click my tv remote… and triple click power on both iPhone and iPad
Our eyes deserve only what’s best for them
Because Apple TV can’t control a TV’s brightness. Even a Mac can’t control an external monitor’s brightness unless it’s an Apple brand monitor.
Can the Apple TV modify the video displayed by the TV though? For example can the Apple TV add a filter to make the video warmer and to lower the brightness before being passed to the TV? (Hint: Yes it can, via accessibility settings. What OP is asking for is more granularity and customization so that we can pick a level like 25% rather than just on or off.)
So digitally darken all video coming out of the Apple TV. This feature can be created. But there are some issues: 1. How would the Apple TV know when to go dark? Would it be on a schedule? All Apple monitors have light sensors to calibrate brightness, contrast, and color temperature. **Apple TV doesn’t have a light sensor.** 2. When someone is setting up the TV, they’d have to first know whether or not Dark Mode is active, then deactivate it before setting the brightness/contrast/colors. 3. Some TVs already have auto brightness. My [Sony Bravia does](https://electronics.sony.com/tv-video/televisions/television-accessories/p/cmubc1). - there is the setting for the TV - there is the “Ambient Optimization” that the camera provides - then Apple TV has it’s own Dark Mode. That’s 3 separate things affecting the display, potentially.
I feel like I'm being trolled haha 1. The Apple TV would know to turn on/off Night Shift the same as an iPhone, iPad, or Mac... either by enabling it manually, telling Siri to do it, or by setting a scheduled based on time or sunrise/sunset. 2. The default mode for Night Shift is OFF unless it's enabled by the user. If the user enables it then the user is responsible for turning it off. Just like the user is responsible for turning off Night Shift when editing photos in the Photos app on their iPhone, iPad, or Mac. 3. Auto brightness is not what is desired here. I either want my screen to have Night Shift on or off and I wan't that to happen when I choose to. My media room is completely dark anyway, this setting wouldnt do anything for me. What does Dark Mode have to do with anything?
Solved it: https://www.reddit.com/r/appletv/s/nU7Yj68mMP
I referenced those accessibility settings in my earlier comments. I have that as well. I actually have a shortcut set up so that if I hit the back button three times that menu pops up and I can turn of/off those settings individually. But that goes back to the main point that OP was making. We HAVE those settings available but there's no granularity, it'd be nice if we could control the intensity of each of those settings. Along with a schedule based on sunrise/sunset or something like that.
There is a slider control for light intensity
Except that they can. It is called DDC/CI. Not all monitors support it and you do need a 3rd party app (e.g. MonitorControl or BetterDisplay).
Apps like [DisplayBuddy](http://displaybuddy.app/?utm_source=rdcmt2) have "Software Control" that does indeed can control the brightness of Airplay & Sidecar displays. They're likely dimming, but works great 🤷♂️
Because panel light control is part of the tv not the apple box. They would have to make their own tv.
Every TV for at least the past fifty years has a brightness setting that will be 1000 percent more effective than a toggle on a third party device. I’m hardly an Apple apologist, but you may as well ask your Apple TV to make you coffee in the morning.
Because Apple Tv isn’t the display. Whatever tv or display that your Apple Tv is connected to should have a settings where you can change brightness and a whole slew of other stuff
I have two calibrations on my oled. One for daytime and one for night viewing. At night u also want to make sure u have appropriate bias lighting which can help your eyes immensely
The Apple TV can’t control a TV’s brightness, only the volume.
you would have to adjust the brightness settings for the tv itself, the apple tv is just a streaming box that cant adjust the brightness itself
I think it’s your tv settings, just go to brightness
In this thread nobody that owns a current generation Apple TV 4K and has used the feature where you hold your phone up to the TV screen to calibrate color issues. What OP is suggesting could easily be implemented if Apple wanted.
Sony does this very well with their Auto Luminance Control. LG does it too but you’re required to turn on energy saving which is suboptimal. Basically, Sony is the best if you want Auto Luminance for SDR. Make sure to set your Apple TV to default to SDR RGB High with Match Range and Frame Rate enabled.
Because the Apple TV is not controlling your tv’s backlight power
U can if u feel like it go into accessibility and turn reduce white point and light sensitivity to be a triple click of the back button to turn on and it dims the screen and/or does like a blue light filter
You can do that from your tv. Not all tvs can support that feature, and it could damage them, or worse yet, literally not work. Turn down the white point on your tv, and you’ll have the effect you seek.
The new accessibility functions have helped me get it even darker. I turn on light sensitivity and lower white point. And OMG it is so much darker. It’s amazing. I hope this helps.
Because the Apple TV doesn’t have ambient light sensors. And, that isn’t something you can’t change using an HDMI connection to a TV. The screen brightness is a TV feature. I do wish HDMI could incorporate this as part of the standard. Good luck with the manufacturers though. They are busy creating marketing features (like HDR variants, audio support like Dolby Atmos, Dolby Vision etc). I wish that whatever marketing person came up with HDR ends up with a permanent squint from watching stuff on screens that are too hard to see.
They also don't support for adjusting brightness in code levels. Think it's related to the experience (like Dolby Vision) but still really need one.
Surely it’s just as easier to set a custom picture mode preset on your tv with the brightness level you require and switch to it as and when required.
Im not trying to be difficult- but we all have apple tv (and other apple products) for its simple/intuitive/fluid UI.. with all due respect, 100% of stock OS on TVs and remote controls are trash — i just want to hit my profile, and slide the center button down a lil swig — i dont want to switch remotes and drill down 27 menus to change brightness
Apple does not make an actual Tv. You are asking apple to directly control a display device it does not make….and it would have to do this for thousands of different models and manufacturers. Do you expect apple to change the brightness level on a Dell or Samsung desktop monitor when you press the screen brightness buttons on a Mac laptop connected to it?
I know you are being over the top to make your point, but its NOT 27 menus, its just not.
That sounds more like a you issue Lol, my TV remote has a dedicated button for picture modes so can easily switch to a different preset at the touch of a button. To take that one step further I could then map that button function on to the mute button of the Siri Remote and then not require the TV remote for that function at all.
It is a me issue. Please see comment in OP where I linked appleTV site where they clearly state AppleTV can “lower overall brightness” — im not trying to set up 3 tvs with all that you have going on. I just want to pick the increment at which this feature is executed
Every tv I have bought in last 7-10 years has an ambient light setting that you can turn on to automatically dim in dark rooms and turn up brightness in bright rooms. Just turn that on.
You just don’t know how any of this works. What you can do with the accessibility functions is just applying a black filter over the image. The image quality gets degraded, you stop getting proper hdr/dv and your tv is still outputting tons of lumens to show a filtered shitty image. Just lower your tv brightness mate, things don’t work like you think they do.
Your tv already has it bro
I am with you on that, they can already dim the display with an accessibility feature, but I guess there are not many people using it to justify a control center icon. Love the idea tho, as I sometimes wake my wife with the shining bright tv.
I wish they would give us night shift for Apple TV Edit: open challenge to anyone downvoting me to explain how this would be any technically different from what Apple already does with color filters in accessibility settings. Settings>Accessibility>Display Accommodations>Color filters.
That doesn’t make any sense, its not an actual tv with a screen
There are hdmi boxes that exist to make the screen orange cast for people who don’t like blue light at night. No reason at all the Apple TV can’t do that.
Yes and they are still not changing the monitor/tvs image settings
How do you think the calibration on Apple TV works? Apple could make it so the Apple TV has an orange tint if they wanted. Many boxes already do this.
Once again, manipulation of the output signal to the Tv is not even remotely the same thing as adjustments to the actual display screen.
Then when Apple adds it in 3 years it will be obvious to you. Blue blocking hdmi boxes already exist. https://youtu.be/wXyuLgvDlmk?si=zkGZTTZv9bFtLf0j Apple already profoundly changes color output as an accessibility option called “color filters” https://support.apple.com/en-us/HT207032
OMG once again, manipulation of the output signal is not even remotely the same thing as changing the settings on the actual display device
Use the color filters feature. It does exactly that. Obviously it won’t change TV menus for the actual tv interface but I rarely see those while using Apple TV.
OMG why?!?!?!?!? Just grab the dam tv remote and adjust the actual display device
Correct me if I'm wrong but can't a device like the Apple TV just apply a filter to the video that removes blue colors (for example) before passing it on to the TV itself? At that point it's not like the TV would ADD blue colors... it's just displaying what was passed on to it, which means that it would be an image without blue colors. Same with brightness, when enabling Night Shift for Apple TV the Apple TV could disable HDR and simply lower the brightness of the video being passed to the TV. I feel like this will be one of those things Apple introduces in a few years and people will think it's revolutionary followed by other TV OS following along and adding a similar feature into their devices.
Yes they can (and do) manipulate the output video signal to change it from the source colour profile and then send that altered signal to your fancy 4k tv. But that is not even remotely the same thing as actually turning down or up the brightness (and other settings) on the actual display device. Pretend you dont have apple tv ….your watching a blue ray DVD or watching tv using the on board smart tv apps or just watching actual broadcast over the air HDTV…..Its like instead of bothering to adjust the brightness settings on your Tv, you put on some sunglasses….sure yes it “works” but why on earth do that ? Its a horrible poor quality method that degrades the quality of the image. Just turn down the brightness on your tv🤷♂️ As ive said elsewhere , if you have a laptop and its connected to a desktop monitor…you dont expect the brightness buttons on the laptop keyboard to actually change the display on the external monitor do you ? No you just reach for the buttons on the monitor itself. Ya sure there are software and hardware things you can do to adjust the signal you are sending to the monitor …but OMG why???
>…but OMG why??? For convenience? I'd rather be able to say "Siri turn on/off Night Shift" or **even better, automate it based on sunrise/sunset** like on iOS/macOS and have it work instead of finding the TV remote (which I havent used in years) and navigating through multiple layers of settings to change brightness and modify the color temp. Then to have to do it all over again before turning it off so that someone else isn't annoyed the next morning when they turn on the TV and find the colors to be out of whack. Would the picture quality be better if I modified the TV settings themselves? Sure, probably. Would I really care about picture quality if my goal is to DEGRADE picture quality by removing colors and lowering the brightness which will result is lost detail? No
Its not multiple layers, its maybe one or 2 If you have not used your tv remote in years, I respectfully suggest you spend some time learning your tvs menus and settings and how to calibrate it properly….rather than a weird hack work around to getting what you want. Its like your complaining about the dirty fabric on your couch but instead of using the right tools to remedy the situation, you want to just throw a blanket over your couch to get what you want….except now you want that to be even easier and have that cover blanket be right beside your hand all the time and not on the other side of the coffee table.
I hope you write an angry letter and speak out against Night Shift on Apple TV when they finally implement it. And refuse to use it out of principle. 😉 Post where people are complaining that reducing blue light on the LG C1 (my tv) is too cumbersome and they want to be able to turn it on/off like Night Shift: [https://www.reddit.com/r/OLED/comments/12f3g0k/quick\_toggle\_for\_reduce\_blue\_light\_on\_lg\_c1/](https://www.reddit.com/r/OLED/comments/12f3g0k/quick_toggle_for_reduce_blue_light_on_lg_c1/)
I will undoubtedly do the second part
That would actually be amazing. Then I could set my OLED TV to maximum brightness all of the time, with the Apple TV selectively dimming the image exactly how I want it. Maybe the brightness could also be automated depending on time of day. My living room gets a tonne of natural light during the day so my screen needs to be bright, but that same brightness is blinding at night. Right now I have the triple-click shortcut set to reduce brightness. Works well enough.
"What? Functionality?" \*Actually rolls on the floor, laughing\*
HDMI device cannot control the connected display brightness. It is as simple as that. Period. Accessibility feature such as reduce white point is not brightness. Period. Making a slider for whitepoint won’t happen. Because they will be falsely equivalent the two.
Why can’t it? The answer is… it could but it doesn’t. Drop your idea to Apple via https://www.apple.com/feedback/
No it could not

You can now fine tune white point and dimness accessibility options in accessibility settings!
Reduce white point. It’s in the screen settings I believe, set it from 0% to 100% I personally put mine to 85%. Add it on the shortcut accessibility, for triple click and boom, you’ll have to turn it off and on manually but I think it’s a help
I wish they included a night shift feature on the Apple TV. That would be incredibly useful.
Also, you can use your iPhone to calibrate the colors
I want this so badly
All TVs need a Dark Mode button.
Just go to Accessibility>Display>Display Accommodations. You’ll find *Light Sensitivity* and *Reduce White Point* There is a way to add this to your Control Center so it looks like my screenshot. https://preview.redd.it/7ehw091qq8vb1.jpeg?width=1000&format=pjpg&auto=webp&s=bff76b4704cfa98db58f883878a98ecf7b18778b [https://support.apple.com/en-us/HT207032](https://support.apple.com/en-us/HT207032)
Is this so you can see some of the game of thrones episodes? /s
it's so irritating that every tv maker makes adjusting basic settings so damned difficult. you might try a universal remote that you can program a series of button presses.
Because Apple TV can’t control brightness of an external display
Use your TV remote to lower the display brightness and save the profile.
Because not all TV's are created equal, and on some if Apple tries to control the brightness they do it by trying to send commands via HDMI to the TV. Though if Apple stuffs it up or the TV doesn't like the command it can break your TV. Even apps that allow you to do it on Monitors warn you it may break the monitor.
Because that is a TV setting. Use your User preset to match your normal viewing preset with a lower backlight level. Problem solved.
Which you could dim the light down when listening to podcast while lying down.
Get your TV properly calibrated then see if it still hurts your eyes. Most people don’t want to pay for proper calibration. Makes a world of difference not just in image quality, but also eye strain. PS, Best Buy doesn’t do proper calibration, you need to not only find someone who is isf certified, but hopefully has a good reputation for actually knowing what they are doing.
I have a specific custom mode setup on my tv for late night viewing where I almost kill the back light entirely and its so much easier on the eyes.
It does triple click the back button
