runnig a 7870 ghz oc 2gb gddr5 with 3 monitors. I have 2 monitors on dvi and the 3rd connected through a regular displayport cable since its a displayport monitor. They are all recognized by windows and catalyst but only the display port monitor is without and image coming through. I tried connecting the monitors to eyefinity and it looks like it works but displayport display is the only one still not showing an image. Ive had this monitor by itself connected through dvi and the image has shown up, so the monitor works.I've also have had problem connecting the monitors through hdmi to card before, both regular hdmi cables and hdmi to dvi cables, so I don't know if it's my card that has issues.
