I want to setup dual monitors. After I learned the The Nvidia FX5500 graphics card that I had was not supported by Windows 7, I went out and bought the Nvidia 8400GS card. When I installed it, the Nvidia 9100 integrated card was no longer available/supported/installed. Specifically, I get get the computer to recognize one or the other graphics cards but not both at the same time. I am running Windows 7 and I have read that others have used this card for dual monitor applications so why can't I get the computer to recognize both graphics cards?
