In my computer is a HD5970 graphic card from sapphire. It has 2x DVI and 1x mini displayport. At the moment I use two screens (one on each DVI). Can I connect a third screen on the displayport or will it not work?
If it has the ports it can use them :p. Mine only had 2 ports on the video card but I found a motherboard laying around with 3 pci-e slots, so I put 3 video cards in it and can use up to 6 displays now
