I had this card in my old set up and was able to run dual screen with both DVI ports, but when I upgraded my hardware and had to reinstall Windows 7, the second DVI port connection no longer became detectable by the operating system. The HDMI port works, and I get dual screen in POST and BIOS with the dual DVI set up, but otherwise I can’t find a way to get the second DVI port to detect. I made sure to have the latest drivers and Windows is fully updated.
