I have a Sony VPL-HS20 on the way and I'm in need of a screen. I'd really like to go with a "board" of some kind at least for now but I'm not sure what is available in NC. I've read about Do-Able which seems make for a good screen but I don't think it's available here. I will probably go to Lowe's and Home Depot just to see if they can special order it. I've also read about Durotherm and Polywall which might be in stores here but it wasn't displayed online. Is there anything else I could be looking for in NC? Also, I've read about people using paint. I'm a little confused as to what materials are typically painted and are regular paints usually used. My room is very dark(pitch black is possible) so should I consider a gray screen? I'm planning for a 100" screen and I'll be sitting about 12' away. Does this sound about right or should I downsize it a bit? If my information is correct, a 100" screen is 49"x87" for a 16:9 ratio, right? I'll test out positioning and size before I mount anything but just looking for opinions. Any feedback is greatly appreciated.
