Hi everyone, I will be buying a screenplay 7205 & I've been advised to use a 0.8 gain grey screen, which surprised me a bit, since I though this was quite a specialist gain. Technical info is 1100 lumens pj brightness, 2200:1 contrast. Screen size would be 80" diagonal (69.7"w X 39.2"h) Viewing distance is 11 ft. Would be viewing most of the time at night & am planning to get blinds, which would get rid of most light during day. Also, area where screen will be is pretty dark area in the room anyway. Can anyone give me any info if this gain is okay with my setup. Additionally, I won't be running pj on full lamp mode. Thanks, Tim.
