I have an ASUS P8Z68-V/GEN3 motherboard and a GeForce GTX 550ti graphics card. I have two monitors connected to the graphics card but wanted to add an additional monitor to the VGA port of the motherboard. For some reason it doesnt detect it in Windows 7 and when checking the BIOS I couldnt find anything that would give the motherboard priority over the graphics card. Any help would be appreciated.
