I am not sure if that is the issue that you are seeing, but you can adjust the color curve in CCC.
Thank you for your reply.
Yes I know I can adjust it in Catalyst.
But the issue was that I never seen that phenomena in the previous releases of Catalysts.
I am using many versions of CCC. I found this version has a few bugs, especially the color display.
I am using msi hd 4670 512 DDR3 VGA, and I feel that its color was a bit harsh.
Of course you can also tune in CCC.
