I just got my panasonic ax200u in and now need to get a screen for it. Im hoping to project at 120inches from 13.5 feet, which uses the projectors zoom feature pretty well. I'll be sitting at roughly the same distance. I've narrowed it down to the Elite Silverframe Matte White and the Elite Silverframe Cinegray. My walls are white and carpet is light colored. I know Elite Silverframe also has a high power gain (1.8) screen for about the same price that got good reviews as well. Any suggestions?
