tv
The couch will be sitting up against the wall and i will be sitting on it so i'd have to say maybe a 13 foot distance. I do plan to dedicate this room for home theatre. I'd like to get a 60 inch if I can, but I don't want to have eye strain, not sure if that distance will hurt or not.
As for the light I have 2 windows mesuring 35X64 each directly behind the couch. I do have window treatments and blinds. I also have recessed lighting in the room.
I am consdering plasma, but have heard bad things about gas that they run on. Once it leaks out, the Tv is shot. Also that the light in the room has to be perfect for the plasma to look right.
As far as dlp only thing I dislike is the bulbs need be changed after a few years and that can get costly.
