I have a Gigabyte 2GB 260x video card that hasn't had any issues up to this point. I've tested several different monitors and cables, but nothing makes a difference. The card has an HDMI port, DisplayPort, DVI-D and DVI-I. I'm currently using a VGA to DVI-I adapter connected to the card, which seems to work fine. However, if I use any kind of digital cable (I've tried all but DisplayPort) the card won't put out any video. So, the ports still work, just not with digital signals. Any ideas?
