Hey Everyone,

I have a Dell Optiplex 740 that I'm using to test Windows 7 on. I have 3 video cards total. 2 are PCI cards and 1 is integrated. Windows sees the Integrated in the device manager but when I go in to the display control to change resolution I cant choose it to extended my screen to. It doesnt even show up in the selection. Only the 2 other cards. I went into the bios and made sure it wasnt disabled, I made sure the right drivers are installed, the cable is plugged in, and the monitor is on and has power. What else could be wrong?

Alot of motherboards don't support using onboard video and a graphic card simulatanously as far as I know.
