I have a 10 x 14 room with a 10' height. The screen will be on a 10x10x10 wall the projector on the ceiling or back wall 14' away. I'm leaning to a painted screen at this point. Wondering what the max screen size I can paint and height off floor. Need to have room L/R of screen for speakers. Not really into 3D or games. Hope this is enough info. What can I get on low end of say $5-600 or at the high side of my budget of $1000 or so.
