    Dual monitor stopped working after windows 10 update


    So yesterday windows 10 decided to do a big update, the one where it reinstalls the os.
    Everything seemed fine, but then I realized that my 2 monitor setup stopped working. It was set as "duplicate" where monitor 2 was the main display and 1 was the secondary.

    In DISPLAY SETTINGS I tried to set it back to duplicate or extend or show only on 1 (it shows only on 2) bit with no success:

    It looks loke windows is doing that and it pops up the regular "do you want to keep settings or revert" thingy, but it actually just leaves monitor 2 as the only display.
    Also, the "make this my main diaplay" is grayed out.
    I tried installing new latest nvidia deiver using DDU, rolling back to older driver, nothing changed. Only thing helping is plugging out the cable of one of the diaplays. Then i can get the one that i want to work and exchange if I want by plugging out the other cable. What now??? Click image for larger version.

    Are you running the system with a GTX 980 TI?

    I would recommend you rollback the Windows 10 upgrade to the version you were previously on and see if the problem remains. If it does not, upgrade the graphics card driver first and upgrade once more.
