Mac Pro (2013- black can) and non mac monitor? I am looking to buy a Mac Pro here in the next month but I'd like to use a Samsung 4k monitor. It has 2, HDMI ports and 1 Displayport. I understand the Mac Pro has thunderbolt2 ports, which, correct me if I'm wrong are the same type of port. Can I take advantage of the 4k capabilities of the samsung using a display port to thundebolt2 connection? thx
Given no detail on the Samsung display, it seems like you should be able to. Thunderbolt ports can handle Displayport connections. The tech specs for the machine claim 3x5k, so a single 4k should be fine. You'll need a Mini DisplayPort to DisplayPort cable.
