I decided to get Sharp 10k, now I am looking into what screen to get. I went to a store and saw demos of Sharp 10k on Stewart perforated white screen and Sharp 9K on Firehawk. The image on firehawk is dim/not punchy, and I did not like it. I was not sure if it was the screen or the 9K problem. I plan to mount my projector on ceiling. I need 106" diag 16x9, sitting distance at 15' and 20', and my room is light controlled. Will hi-power white screen be good for my application?
