So I thought I'd hook up a 4K display to my home computer even though I may run it at 1080 just to see if it would work. The display (a Sharp PN-K321) has 2 HDMI connectors and a DisplayPort connector. The display should run 3,840 x 2,160 at 30Hz on one HDMI and 3,840 x 2,160 at 60Hz with 2 HDMIs or the DisplayPort. My video card is an nVidia GeForce GTX 560 Ti with 2 DVI and one HDMI connectors, like this:
When I plug in the HDMI to the Sharp display I get no video whatsoever. Do I need a DisplayLink to DVI or dual DVI cable?
