    Samsung CF791 - Screen flickering in certain situations - 280X

    hsanchezv

      Hello,

       

      I've bought Samsung CF791 monitor (3440x1440) coming from a 1080p monitor.

       

      The problem is I'm getting flickering on desktop when moving cursor on windows, but surprisingly, the flickering isn't happening while I'm in game or when I plug a second monitor in extended mode and the new monitor as main, so fortunately it seems is not a monitor problem (or that I think).

       

      I've tried with 17.4.4, 17.7.1 and 17.7.2 drivers. Also install monitor drivers, both HDMI and Display Port cables,  60hz~100hz frequencies...

       

      Monitor: CF791 using DisplayPort 1.2

      SO: Windows 10 Pro (creators update)

      GPU: 280X (waiting for Vega, that's the point of a ultrawide QHD monitor, but can be my old GPU having bad response with the monitor?)

      Memory: OC 2933mhz (maybe a memory leak issue caused by the OC?)

       

      I'am fine with the solutions I found, but I would love to solve this annoying problem.

       

      All ideas are welcomed.

       

      Regards.
