I am confused about HDMI — I have a GTX 770 with 1xDP, 1xHDMI and 2xDVI. I just bought two Dell Ultra HD 4k Monitors (P2715Q) and while the first one gives me 60HZ over DP, another only shows 30HZ over HDMI. Does it mean that I need to replace my video card with the card that has 2+ DP ports? Or it means that my HDMI cables are crappy? I tried 2 different HDMI cables…

The GTX 770 specifications page states:
So yes, you will need a graphics card with either two DisplayPort connectors or one that has HDMI 2.0 rather than the HDMI 1.4 that is supported by the 770.
