I am running on a MSI K8N Diamond Plus Motherboard with an XFX Nvidia Gforce 7600 GT (256MB). It has dual DVI's. I was able to do dual monitors in XP, but in Windows 7 it will not work. It see's both monitors, but for some reason, it thinks my second port is a VGA port and I cannot change it. (thats from the NVidia tool...) Anyone else in this great big world have this issue, or can someone lend a hand? thank you.
