I've had this setup for a few days, so I'm still trying to get everything right. My main monitor is going through the vga on a PNY nvidia 240gt pci-e, and I'm trying to get it to recognize the second monitor through the onboard vga (ati radeon 2100?). I'm running Windows 7 32-bit, I can use either monitor when I boot, but I can never see the second monitor once it is booted. Ie: I boot on the onboard monitor and I cant see the pci-e monitor and when I boot with the pci-e as my main I can't see the onboard monitor. I can't really spend any more money for a few more weeks, since I just did a major upgrade, so please don't tell me to buy another card or a dvi/vga adapter.
