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?

    I've edited your question and in the process removed the "side question". Besides the fact this site works best when each question is focused on a single issue, that part of your post was also off-topic as it was primarily opinion based. After all, no-one here is going to know if the ghosting was always present and you just didn't notice it. All the best with your main question. :) – Monomeeth Sep 5 '19 at 21:21

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.

  • Thanks Jeremy! Is this a limitation of the monitor, the cable, or the Mac? – Maury Markowitz Sep 6 '19 at 15:08
  • Also, can I get USB on the monitor by connecting a USB to the Mac? Or is that something's that's up to the monitor and may be dependant on that? – Maury Markowitz Sep 6 '19 at 15:14
  • If the monitor had a Thunderbolt connection then you would be able to use a Thunderbolt cable and get data along with the video signal. – Jeremy Pinnix Sep 6 '19 at 22:41
  • It is really up to how the USB ports are set up on the monitor as to whether or not that will work. – Jeremy Pinnix Sep 6 '19 at 22:42

All Thunderbolt ports are also DisplayPort ports, but not all DisplayPort-capable ports carry Thunderbolt. The six shaved-squared-corners Thunderbolt 2 ports on your Mac Pro actually start out as Mini DisplayPort, and appeared under that name as video outputs a full year before we saw our first Thunderbolt logo on anything.

If your new display just has regular DisplayPort inputs, a simple cable with MiniDP on one end and DP on t'other will be more than adequate.
