Connect 4k display to the 2013 Mac Pro? I have an Apple Cinema Display circa 2007. It's attached to my 2013 Mac Pro via a HDMI/USB breakout cable connected to one of the Thunderbolt 2 ports and into one of the D300s.

The display has recently begun showing a sort of "ghost image" of closed windows and such, so I have started to look at the ASUS PA329Q as a potential replacement. 

My question is:

Since it has a miniDisplayPort 1.2 port, can I plug a cable directly from my thunderbolt port to this port?
    If so:


Will it drive the full 3840 x 2160 without problem?
Will that single cable make the USB ports on the monitor work?
It will drive the full 3840 x 2160 without problem. However, it will only be carrying video signal, not data or power. As such, it will not make the USB ports on the monitor work.
