At my house we’ve been using projectors for watching TV for about 10 years now. A ton of space is being saved by mounting a projector on the ceiling.
It turns out that the wall doesn’t even need to be completely flat or perfectly white. I’ll never go back to a “traditional” TV , I prefer a 10’ HD screen.
If you like to watch TV during the day with a lot of ambient light, then a projector may seem a bit dim but you certainly don’t need a darkroom for it to work well.
