I have 2.

Beautiful picture but it's 28hz @ 4k. This causes a "lag" between the mouse and cursor that is completely unbearable for me (not a gamer, I'm talking just web browsing / email / coding), and I've pretty much stopped hooking them up. Try adjusting your display settings to sub-30hz to see what it feels like.

To be fair that is a limitation of HDMI 1.4. You'd have the same problem if you bought the ASUS PQ321Q and connected it with HDMI.

Personally, I'd never buy an HDMI anything...DisplayPort is the current standard and the future of displays.
