Hi all.
I currently have my PC connected up to a LCD projector via VGA from my Radeon 9700. This has highlighted a slight flaw in the projector construction in that there is slight panel mis-alignment between red, green and blue.
This shows as a faint coloured fringe on high contrast edges. It appears as though the panels are out by about 1 full pixel, which when watching movies is not really noticable, but PC text could be sharper if the problem was eliminated.
Now the obvious solution is to return the projector for adjusment, but as the problem is only slight, I don't want to run the risk of causing other problems, and I think 1 pixel out is within tolerance anyway.
What I was wondering is if it is possible to correct this in software by moving the individual colour channel values by 1 or 2 pixels in any direction. For example if this is the blue channel information for a portion of the screen:
23,45,234,154,128,99
76,12,14,212,98,96
11,55,203,19,185,18,
91,100,255,255,109,72
If in software I could move the blue channel up 1 pixel, these blue channel values would become:
76,12,14,212,98,96
11,55,203,19,185,18,
91,100,255,255,109,72
0,0,0,0,0,0
(Note all values moved vertically upwards)
It would be great if this was possible through the drivers, or is there a 'driver add-on' that would allow this?
Many thanks in advance
Cheers, Beastie.
