I was having a play the other day in the service menu where you can change the GAIN/BIAS settings. As a test I looked at one of the icons on my desktop (a CDROM icon with various shades of grey!) which looked very good. I increased the GAIN for r/g/b by 10 in the service menu which made the colours more vivid on the screen but obviously this CDROM icon on the desktop had now lost its detail because the whites were being crushed. I turned the projector contrast down by about 10 and the detail returned because the whites were no longer 'crushed'. I was wondering if the gain is the same as the contrast setting?, if not is it better to have a high gain for each r/g/b in the service menu and a much lower contrast setting on the projector?. For example if the settings were -- setup #1 gain red=64 green=60 blue=74 contrast 70 -- setup #2 gain red=104 green=100 blue=114 contrast 30 -- As long as a greyscale test pattern made sure that all the greys were being displayed which would be theoretically better?
