I'm getting ready to paint my wall for my soon to come Infocus X1. What color should I get for a DLP projector like the X1? I read alot about tropics grey, is that for LCD's and DLP's? Also what is a good size for a 16' to 17' viewing distance from the screen? The room is 22'x20'. I want the bigest with the best image still. I think it will be a 16:9 but not sure yet. If anyone can give me a size for a 4:3 and a 16:9, that way I can have a ballpark idea of what to do. Thanks if you can help.
