    This happens at random. Sometimes just after logging in. Other times after some minutes. Sometimes hours. Most often somewhat quickly though.
    Startmenu shows and when hovering mouse over open apps they show up on the primary monitor.

    Color Display on 2nd monitor

    I am using Windows 10 on a Dell laptop with a 2nd monitor which has been working fine. For some unknown reason I have suddenly lost the full color range on the 2nd monitor. I don't know if I have changed some setting by accident or what. I have tried
    resetting the defaults but that didn't change anything on the 2nd monitor. The primary screen on the laptop continues to work fine. Any suggestions what needs to be done to restore the full color range on monitor #2?

    Primary Monitor goes black

    I have 2 NVIDIA GeForce GTX 560 graphics cards in SLI and 2 monitors (a Dell connected via DVI and a Samsung connected via a DVI->HDMI -> HDMI mini) About a month ago after the Windows Feature Pack update, I started having issues with my monitors. When
    only one is plugged in they work fine, so I know there isn't an issue with the cables. When I plug in the 2nd monitor, it works, but the primary screen goes black. If I open any programs, the still open on the primary screen and I have to use Windows + <Left
    or Right> to move it from the primary monitor to the secondary monitor. If I open the display settings, and switch which monitor is marked as primary, it disconnects both monitors, then brings them both back on, and both display properly. But the primary
    goes black again when my computer goes to sleep or is restarted. I have confirmed installed the latest NVIDIA driver this afternoon, and I still have this issue. I have tried the following:

    - changing which ports/graphics cards each monitor is plugged into

    - confirmed the Dell monitor's drivers are up to date (the Samsung is a generic PnP)

    - uninstalled the Display Adapters completely (it switched to using the default windows driver, but still didn't work)

    - unplugged the computer and the monitors for 5 minutes then reconnected them

    - scanned my computer for corrupt files using sfc /scannow

    Any help you be greatly appreciated, as it is very annoying to have to guess that I'm logging in, and then switch my main display every time I want to use my computer.

    Primary Monitor goes black

    I posted this same exact question in January. I was able to get it resolved by performing an In-Place upgrade, as suggested. That worked, until about a week ago. Now I am having the same exact issue again. I tried
    doing an In-Place upgrade again, and it did not resolve the issue this time. I also confirmed that my NVIDIA drivers are up to date as well (I installed them yesterday).
