I just bought this brand new monitor and maybe the second time I used it the screen started to turn off and on, and the image distorted. This happens intermittently without any specific trigger as far as I can tell. It does not happen any more or less frequently when the GPU is under load. Setting the resolution to 1080p and back to 4K usually fixes it. Unplugging the displayport cable and plugging it back it also fixes it. However even when it is "fixed" I still see something like tearing in the middle of the screen intermittently. I've never seen it happen at lower resolutions, but I haven't left it in a lower resolution for long. What I've tried: - Re-installed the drivers using CCleaner. - Ran a stress test with OCCT at both 1080p and 4K, no problems - Bought a new cable, does not even work at 4K! Display turns on and off without ever showing the desktop. (Do all displayport cables support 4K @ 60Hz?) - checked many times whether the cable is correctly plugged in (although at the GPU end it feels a little loose, the tiny screw almost seems to be in the way. But how can that be possible?) - Gaming is always smooth and beautiful at 4K, no BSoD or artifacts Any ideas on how I can fix this? What could be the cause: GPU, monitor or cable? Anyone have a similar issue? P.S.: Temperatures are always within the normal range.
