4 monitor setup -How to run 2 video cards on ASUS P5Q Pro motherboard? Tags: Asus Graphics Cards Monitors Motherboards Last response: February 23, 2012 6:45 AM in Motherboards Share empiretna February 22, 2012 1:48:11 PM I want to make a 4 monitor setup and have a P5Q Pro ASUS motherboard with two PCI-EX slots. I have 4 different video cards and none of them seem be work with each other. I tried every combination. All cards work on their own, but if both pci-express slots have a video card plugged in, then only one video card works. The video cards are all different models, although two of them have the same chip which is Geforce 8400 GS Is there a setting in the BIOS i have turn on so it runs both video cards? Or what am I missing/or doing wrong?

No boot up and go get the newest driver from nvideas site and install should find both and then give it a try.. Thent empiretna February 23, 2012 5:34:02 AM Thanks Now when I power up the system, only 3 monitors end up working. For some reason on the 2nd PCI-e card, the DVI output does not work. (Im using DVI-I > VGA, checked the cables, etc to make sure that isn't it) Any idea why? Can't find your answer ? Ask !
