Agree that biggest issue will be ambient light and lumen output from the projector. I have a projector setup in one room and it is tough to use until the sun really starts to fade in the opposite direction, even with heavy curtains. Mine is a BenQ, somewhere sround 4000 lumens, it sits about 12 feet away and has about a 120" projection onto a blank wall. I do like the setup for things like the super bowl, etc. but I have a 55" TV for gaming/computer monitor in my office that gets more use on a regular basis.
