So let us just establish things clearly. You changed the plugs on the monitors on the video card end? And in doing so you identified that the culprit is the video card and not the monitor? There are three variables here and your explanation is sort of vague: there are monitors, there are cords, and there are video cards. Now which cords are you using? All HDMI? DVI? You should be able to narrow down whether there's a hardware problem with a specific video card by switching around cables and cable types.
If you don't simply have a faulty cable, you either have a faulty video card or a faulty specific output on an otherwise good video card (still should RMA it obviously).
Ok I have three cards each card has two outputs. So I have card 1, 2 and 3 each card has two DVI outputs A and B, I also have three monitors (from left to right) AZ, AX, and AC.
I started with (also shown above in the screen shoots) monitor AX plugged into 1-A, monitor AC plugged into 1-B and Monitor AZ plugged into 2-A. Card 3 has nothing plugged into it.
What I did was unplug the DVI cable coming from monitor AC that’s plugged into card 2-A and moved it to DVI output 3-A then moved AX from 1-B to the output 2-A that I just took AC off of. So know I have a monitor on each card.
So know the problem changed monitors because I changed what monitor was plugged into 2-A.
You did bring up a good point I did not think about the cable. But it did it on AZ’s DVI cable and AC’s DVI cable, so I am guessing it’s not the monitor or the cable. So I still have four things it could be, the card, card output 2-A, SLI Bridge or PCI slot.
