hdmi in black and white

[rockster40]

posted this on microsoft answers too... nothing useful yet.

built myself a screamer, core i7 920, gigabyte x58, 6gb triple channel ocz ram and a powercolor (ati) 5770. got it running, hooked it up via hdmi to my sony bravia 40" and everything was sweet. after about a week, the color disappeared. i get color on the sony during POST and the windows 7 (x64) logo but as soon as windows loads: no color on the sony. if i switch to vga, i get color. but it is a 30 foot run to the sony and i get ghosting via vga. i have checked and rechecked all color and resolution settings in both windows and catalyst 10.2 control panels. i was about to rma the video card but the color during POST and windows startup makes me think it will do no good. i have been scouring google for answers but as yet i haven't found the answer.

help anyone?

It will be a setting in CCC. Open CCC - Desktop & Displays - Right click on small HDTV - Configure - Colour - Saturation - set to 100. Also check that the correct pixel format is set.

resolved!!!

well, first of all, in ccc 10.2 the color settings where you described does NOT have saturation. there is a saturation setting under "avivo video", which was set to 110. but while i was playing around with the advanced color settings i decided to reset all to factory defaults... bingo!

i still have no idea which setting was out of whack (nor what caused it in the first place), but obviously something was.



thanks for looking and i hope this helps someone else who is as lost as i was.
