Unable to Extend Desktop

post #1 of 4
Thread Starter 
So I recently just got a 7970 installed and I have all the latest drivers but it won't let me extend my desktop across 3 monitors. I have one monitor plugged into DVI Digital, one in DVI Analog, and another in HDMI. Everytime I use Catalyst Control Center and try to extend the display to all 3 monitors it says I must disable another monitor. Any ideas on why this is happening to me? The exact same set up worked with my old 660 ti.

you might need to use a display port or another connector other than the hdmi

The single-link DVI and HDMI ports are shared on AMD cards. You can use only 1 at a time.
