    Black screen and flickering at 4k 60hz on AOC U2868PQU and ASUS R9 290X DirectCU II 4GB



      Windows 10 64-bit

      16GB DDR3 ram

      ASUS R9 290X DirectCU II 4GB overclocked

      Intel Core i5 4670k stock

      Samsung EVO 850 500GB

      Gigabyte GA-Z87X-D3H

      PSU 850 watt



      AOC U2868PQU



      After i upgraded my gpu from 670 sli to a 290x i've had flickering, black screens and thick grey lines on my monitor while running it at 60hz in 4k. If i run it at 30hz or a lower resolution all my problems disappear. I've had the problem since i upgraded in may 2015 and i have no idea what to do. I've tried using a different cable, two actually, but it changes nothing.


      I am currently running the 15.9.1 driver.
