Does anyone have any recommendations for screen material for a low-light-output LCD projector? Specifically, I'm talking about a 350 lumen, 200:1 contrast unit. On the one hand, this isn't much by the way of brightness and I don't have great light control in the viewing room. On the other hand, I'm planning on using it after sunset about 85% of the time, and because of room dimensions, I can only use a pretty small screen size of around 70x40 inches (16x9).
Again, because of the setup of the room, I need a screen that isn't visible at all times. (It most likely will be placed directly in front of the TV). Because of that at the not-too-big dimensions, I'm thinking about a Da-Lite tripod, such as the Picture King. (Does anyone here have anything positive or negative to say about them?) What I'm much less certain about is what material to use. The most obvious choices are glass beaded, with a viewing angle of 30 degrees and a gain of 2.5; and video spectra, with a viewing angle of 35 degrees and a gain of 1.5.
Of course, what I'm most interested in is the trade-off between getting a picture that is bright, vivid, and colorful enough to enjoy without decreasing by too much the typically poor LCD black level performance.
Thanks for the help!
