Any help is appreciated.
I bought an epson 8700ub and love it. Ive got it in a room thats about 13x17. Its just sitting on a table with no screen. Its at max zoom and the lens is about 10.5-11ft from the wall. I measured about 110 inches. It looks great even on the wall. I wish the brightness was a little better,but im sure that wil increase when a screen is added. I have pictures of the room if that will help but had a few questions.
-what is the gain of a medium brown flat wall..if that is even measurable. I'm just trying to gage how much of an increase in brightness I can expect.
-im looking at a 106-110 inch diagonal white 16:9 screen. Im wanting an increase in brightness but don't want to lose that much viewing angle. Would a modest gain,say 1.3-1.5,be appropriate?
-i have a budget of 500
