A few months ago I wrote about, “hiding the TV”
This past summer we used a product called Wallpaper TV.
This TV is so thin it looks like a picture on the wall, not a box with an articulating wall-mount- thing-a-mu-jig.
What is neat about this is that when not in use, it can display an image that looks like art, a beautiful scene or a family photo. This greatly helps the architect and the craftsmen to design and build a better-looking room.
Nice ones are still very expensive; however, I suspect like all things in electronics, the price will significantly drop in time.
