I just recieved my GTX 670 2gb today. I am trying to set up Nvidia Surround. I have 3 Identical monitors that all are native 1920x1080. When I try to set up surround the max display I can get is 3840x800. I am using an HDMI and 2 DVI ports. What am I doing wrong? Do I have to have dual link dvi cables, or do I have to use the displayport? This resolution looks aweful!
