Windows 10: Maximized applications cause monitor to shut off. Solved

  1.    12 May 2017 #1

    Maximized applications cause monitor to shut off.


    I started having this issue about 4 days ago. Their have been a slew of updates from Windows 10 and from my GPU. When an application is Maximized, it causes my monitor to sometimes go to sleep. It is not 100% of the time, it is about 70-80% of the time.

    Chrome causes it to happen whenever swapping tabs in a Maximized window, or opening a new tab. Windows applications like file explorer, settings, etc... seem to be 100% when maximized.

    I have an LG27UD68 monitor using display port 1.2 at 4K 60hz. My GPU is a GTX 1080. Their have been no hardware changes.

    I have tried a complete fresh uninstall of my GPU driver using the clean uninstall utility. I also tried downgrading to the last WHQL version of my GPU driver (also using the clean uninstall utility).

    It was the OnScreen Monitor utility for this LG monitor. Uninstalling it fixed the problem.
