I'm using the dvi dual link cable, I've updated my AMD drivers, I've updated the monitor with the drivers on the cd. I don't know what else to do. Help!
Edit: I can't change my refresh rate to 144.
Have you tried both DVI-D ports, sometimes one either is malfunctioning, or is not dual link. I've also heard and have personally experienced issues with a 2nd monitor hooked up that was not 120hz.
