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.
