    Second display keeps flashing off and back on and resizing windows


    Since recent update, my external monitor primary display keeps flashing off for a moment - my laptop screen then flashes on with all windows, then the external monitor flashes back on but all windows are resized. This happens every 45 seconds or so.


    I am using a Windows Surface Book and Windows 10. My Windows Surface Book has never worked properly with external monitor - even though I have replaced computer twice and monitor once. But it has always been useable though frustrating until now.

    :)

    Hi,

    There are many possible reasons why the screen keeps flashing, like outdated display drivers or corrupted user profile.

    Please answer the following questions for us not to repeat the same troubleshooting steps:

    • What are the troubleshooting steps you have performed to resolve the issue?
    • Have you tried to update the display drivers?
    • Have you tried to check Windows update?

  3. Second Screen Display keeps resizing.

    My second screen will occasionally resize to where there is unused screen space on the edges of the screen. I try and re-set the aspect ratio but it does nothing leading me to believe its on my PC's end. I then try it again in my right-click Display settings
    but the empty space is still there. It must be a deeper issue but I'm not overly savvy when it comes to deeper display setting. I don't even know where to look or start. Any help would be appreciated. I should add I'm not using pc monitors but small TV's.
