I use ATI 780G motherboard, when use onboard RGB, every thing is ok.

but when i connect onboard hdmi to hdmi of LG, the black desktop background looks grey.


when i play video, the color in video seems ok. but the top and bottom black bar also looks grey.


so i reinstall vista x86, the black is black. just after i installed ati catalyst 8.6, the grey returns.


i tried UseBT601CSC=1, but it doesn't work.


can someone help me?
