I am currently running one ATI 5970 GPU and it says it can support up to three displays. I have two dvi to hdmi converters hooked up and one mini displayport to hdmi hooked up. Since most of the monitors you can buy at a store only have hdmi or vga. Could someone please help me in finding a solution. It shows that all three monitors are connected, however it only lets me run 2 at a time.
