I'm planning my first projection system - exciting times! I'll be repurposing basement storage space, creating a rectangular theater room that's 13½' long by 7½' wide by just 6½' tall. Wish it was larger, but that's the best I can do. With allowance for screen frame, I can't go much bigger than 80" wide, so I'm planning an 80"x45" 16x9 screen, with all front speakers beneath the screen. I'd prefer the speakers to the sides of the screen, but that would mean a much smaller screen :-(.
Seating will be a couch at the very back of the room, plus a couple of bean bags for the kids just in front, and to either side, of the couch.
Intended use is 60% movies, 25% sports, 15% gaming. I have complete light control, but would prefer a little ambient light for movies, more for sports, and more still for gaming. All lighting will be new, so I have flexibility there. Décor will probably consist of a black curtain behind the screen, and mid-to-dark walls. Not sure how dark I can go on the ceiling - probably a mid-gray.
Based on reviews and bang for the buck, my projector shortlist consists of the Epson 5350, though I'm open to (cheaper) 1080p 2D alternatives if they'd better suit my space. The throw will be 13'7" (through hole into next basement room), for a 2.0 throw ratio - either ceiling mounted, or on a high shelf; it could come forward or back a bit if necessary.
Which brings me to my screen. I'm thinking a hanging, painted and framed 16:9 Thrifty White.
Based on the above, what DUI screen paint do you recommend?
