krs360 Posted July 7, 2017 Share Posted July 7, 2017 Hello people! Anyone have experience of their 4k monitor not working correctly on OSX? I don't seem to be able to use anything above 2k without getting a black screen. The machine is still on and working fine as I can VNC into it and change the res back to 2k. Using Display Port cable, the monitor is DP 1.2 so there's no issue there. Works under Windows @ 4k 60hz just fine. Nvidia Web Drivers installed with acceleration enabled. Using Clover as the boot loader. Any ideas? Thanks! Link to comment Share on other sites More sharing options...
