I plan to connect a new 4K display to my GTX 980 SC ACX 2.0. I understand to get a 2160x3840/60 signal I should use either the HDMI 2.0 or Displayport 1.2 connections. I will use the Displayport as this monitor only has HDMI 1.4. Is there anything special I should know about using this DP output? It looks like there are 3 DP connections on the card, I assume so it can run 3 monitors, I will have a single screen. Will any of these work as well as the others?
