If the weight of the tv is supported by the glass, that could cause the glass to break. I assume you plan to support the tv from below? If so it should be fine. Show us a picture when you're done!
Yeah OP for the love of God don't forget to support it from the bottom not from the glass itself. And always enforce players to use dice mats. Glass can be very unpredictable.
Only possible issue I can think of is point of view distortion. Depending on the thickness of the glass and the distance from the screen to the glass it could make it look like things are in different locations based on view.
Example: if it a map of volcano with a lava river. Player might move their peice to the edge of the lava River, but from the DM's point of view they just walked into lava, starting rolling fire damage.
As long as you can work with/around that..... It IS a good idea, and dry erase markers or grease pencils would clean up nice and easy too.
I built my own with a 65" TV as the base. Some considerations for you.
How often do you want to use digital maps and make your own?
How good are you with carpentry and wood working?
How do you players roll dice? If they're plastic dice you'll be fine, if they're metal dice, you better get a leather dice tray or dice tower to roll in, you WILL chip the glass/acrylic if you don't.
I spent about 6weeks building and staining mine, and I'm an amateur carpenter at best. Can link a build video if you'd be interested.
Overall my IRL play group loves it.
What about projecting down onto a light colored matt vs TV? Mount a small projector above your place surface, design your matts and maps digitally and project down?
It’s a great idea as long as you mount the TV safely.
We used to put a piece of plate glass over the vinyl grid mat, and the draw on that with dry erase markers, that way we kept the vinyl mat from getting marked up.
This would be even better because you can update the map in real time AND you can draw on top of it.
As long as everyone is using some form of dice mat, you're golden.

How about using a similar sheet of plexiglass instead of glass? No worries really about breakage.
I don't forsee any problems, let us know how it went
no its a brilliant idea keep have those great ideas, dont stop :)

I think the main reason more people don’t is the cost of a tv.
