After reading many threads in these forums about how the rated brightness of a projector doesn't mean much in the real world I would like to know how to tell if a projector is bright enough to use in a room with quite a bit of ambient light. In one of my classes there is a Mitsubishi LCD projector (model unknown) that displays a very bright and clear picture even when the lights are on. There is even a light directly over the screen and the picture is still very bright and detailed. That's what I would want. I think that Mitsubishi is only 800x600 though and I would want 1280x1024. I have been looking at the Panasonic PT-AE700U. I doubt that would have comparable brightness. Would it?
