For some reason when I hook my computer (8800gt DVI) up to my 1080p sharp aquos with a dvi-hdmi connection or dvi-hdmi cord the picture flickers. To describe the flickering it only seems to affect the contrast and it doesn't flicker very fast, it seems to flicker variably every few seconds. When I hooked my computer up to my tv with DVI-HDMI when I had a 7600gt in it I never got any flickering. Driver cleaning+reinstalling doesn't do anything. Is there some setting that could be causing this?
