I posted this in a separate thread as well, but was hoping to get a response from someone at AVS.
I currently have a dedicated home theater room with complete light control. The ceiling and walls are white, the carpet beige, and the screen area is flanked by espresso (very, very dark brown) velvet curtains. The Sony Black Pearl projector (which I purchased from AVS) is at a throw distance of 15 feet and is on a shelf 5 feet high, behind the seating area. The seating distance from the screen is 11.5 feet. I have been enjoying Blu-ray and HD DVD movies on my white textured wall for several months, but can't help but think a screen would be significantly better. I am not sure whether or not to go with a white screen (Stewart studiotek 130) since I have complete light control, or consider a grey screen, such as the Stewart Firehawk, due to the white ceiling and white side walls. I plan on a 16:9, 100" diagonal screen size. Please comment on whether or not the Black Pearl would provide and adequately bright picture at this screen size and throw distance taking into account the gain of the recommended screen. Any insight/recommendations would be greatly appreciated.
