I'm having a tough time sorting this out. I just got an InFocus 4805 for my basement HT (make that basement HT to be, haven't moved there yet). I was looking at getting either a 92" or 106" Da-lite model B HDTV pull down screen. The projector will be ceiling mounted and the room should be pretty darn dark (only two small windows that I can cover well). My concern is trying to figure out which surface to go with, matte white, high contrast, high power, video spectra.... Near as I can figure the main advantages of the more expensive surfaces are that they do better with ambient light. But I've also read that some of them do better with wrinkles too. Any help appreciated.
