I have a DIY matte white duck cloth (gain of 0.9 to 1) now with my Sony VPL-CX1 on a shelf 2 feet above my head against the back wall. Its image is great but I want to leave more lights on for wife to read a book so I'm trying to find a higher gain screen. With the lights on enough to read comfortably, currently the night scenes are dim but daytime scenes are OK. So I thought a higher gain screen may improve my ambient light level and image brightness. The size I wanted was 69X92 for $160 at www.cousinsvideo.com
model B Dalite glass-beaded, gain of 2.5. Hi power probably would be better but is $100 more ($262). Thanks for replying.
