    I've had this same problem on my Acer CZ340CK for 2 years.   The only way to make the problem go away is to use the HDMI port on the monitor.  The 2 DP ports are unusable because of this issue.   The screen blanks out for a few seconds, every few minutes.  Power cycling the monitor will briefly help, but the problem comes back after 10 minutes.  Other monitors work fine with the same DP cable and video card (I've tried 3 different cables).    The problem happens in both games and when just using the windows desktop  (running at 3440 x 1440 @ 60 Hz).   The problem seems to happen less if I reduce the resolution to 2560 x 1440 60Hz.   My video card is an Nvidia Quadro M5000M.

    Any ways to fix this problem? I have overdrive turned off.   My only work arounds at the moment are:
    1)  Run at 2560 x 1440 using the display port on the Acer
    2)  Use a DP to HDMI adapter and use the HDMI 2.1 port on the monitor. 

    I'm using the 2nd work around at the moment, since it's the only way I can run full resolution.
