I have been putting together my home theater, and purchased a Sony VPL-VW10HT, and a 16:9 119inch diagonal Da-Lite High power screen. I bought the HP screen because of its reported very bright picture even in relatively high ambient light situations. I must say that the projector has undergone no adjustments, but even in low light viewing, with the viewing occurring from as close as possible to the projector lens (the HP screen is retro-reflective, and the maximum light reflectance occurs the light source), I find the picture not to be very bright at all. I have been doing my initial viewing in the Cinema black mode, and when I turn the cinema black mode off, the picture does brighten up, but nowhere to the point where the picture could be considered to be good in relatively normal ambient light. Anyone have any thoughts on what might be going on?
