I just bought a Screenplay 7210 and am looking for a 8ft wide screen to go with it. Im new to this so I dont know anything about type of screen, what gain, etc. I cant use a fixed screen, but Im happy to go with a manual pull down screen for the moment to keep the costs down. I should be able to get near back-out conditions in my room, although the walls are quite light, if that makes a difference. What would you guys suggest? Does the material matter or should I just be looking at the gain?
