    Maximized Applications - Monitor Shuts Off


    I started having this issue about two weeks 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).

    I have noticed on my laptop that the power options I set for the screen turning off changes from none to 20 minutes under the 'plugged in' option, I've set it back to none but it seems to change back after an update, it's done it several times since the Cr Up.
    You might have the same problem.

    That isnt the issue for me, mine is definitely caused by maximized applications. Any application that is maximized will instantly turn make my monitor disconnect as if there is not enough bandwidth on the cable to transfer the 4k 60 fps image to my screen. I will probably attempt to buy a new cable sometime next week.
