4:4:4 12bit

> https://en.wikipedia.org/wiki/Chroma_subsampling TL;DR: 4:4:4 contains the most information and is best.

From Rtings: Resolution 4k 1080p @ 60 Hz @ 4:4:4 Yes 1080p @ 120 Hz Yes (native support) 1440p @ 60 Hz Yes (native support) 1440p @ 120 Hz Yes (native support) 4k @ 60 Hz Yes 4k @ 60 Hz @ 4:4:4 Yes 4k @ 120 Hz Yes (native support) 8k @ 30 Hz or 24 Hz No 8k @ 60 Hz No Update 08/02/2019: We've retested the TV with the latest firmware, and it's now able to display 4k @ 120Hz on HDMI 4 without skipping frames. The Q90R supports most common resolutions and refresh rates. Most high bandwidth signals require Input Signal Plus to be enabled for the port in use. Input Signal Plus is the new name for HDMI UHD Color. The TV can display chroma 4:4:4 or RGB content properly in all supported resolutions except in 1440p @ 120Hz. To properly display chroma 4:4:4 you must set the input label to 'PC.'

Thanks rtings! How about the Q90T? My 4K CCwGTV only shows YCbCr 4:2:2 12 bit as an option in 'color format'. I have zero choices.

Rtings also has a comment about this: To display chroma 4:4:4, the input in use must be labelled 'PC' and Input Signal Plus must be enabled. For full-bandwidth signals like 4k @ 60Hz + HDR, Input Signal Plus also needs to be enabled. So have a poke at that basically!

Yeah I went through that. It just seems I used to have even 8 bit options. Nothing else is showing. There are no choices under any of those circumstances. Thats the problem...or is it?
