I'm built a PC a few hours ago and assumed I didn't have the correct DVI cable to connect my GPU up to my monitor (which I don't) so I used HDMI. I dunno what's happening. Tomorrow I'll go out to BestBuy and buy a Dual Link DVI-D, but I'm confused as to why HDMI doesn't work as a video output right now. Any help? (first build BTW yay)
