Q: Why is my 4K display not working with macOS on a mac pro?
I have a 2013 Mac Pro (Darth Vader garbage can) edition. I just upgraded today to MacOS from OS 11.11 El Capitan.
My 4K AOC monitor (U2879VF) is no longer working. It is connect to the MacPro using a miniDisplay port to Display port cable. It was working fine with El Capitan.
Any thoughts?
Mac Pro, macOS Sierra (10.12)

I was able to fix the problem. I had to reset the PRAM on my system by using the Option-Cmd-P-R key sequence when rebooting my system.
