In my previous home, I had a Panasonic AE8000U projector and the image was 138 inches wide (160 diagonal) and we sat about 15 feet from the screen. My new home has a room that is 14 feet deep that I would like to so something similar. The image can be smaller say 150 diagonal since we will be sitting one foot closer. I will be using a BenQ HT3550 projector and watching mostly 3-D films. It's not a bright as the AE8000 so I need a screen with a lot of gain, maybe 1.3? Anyone have any perforated screens at 150 inch diagonal that they can recommend?
