    computer can't detect second monitor


    I recently restored my system from a recovery usb stick. I am currently dual booting Windows and Linux. When I use Linux, my computer can use the second monitor just fine, so the monitor itself works. When I go to Display and click Detect, it says "Didn't detect another display." When I go to Device Manager and click Monitors, there is only one monitor there. I have tried updating my NVIDIA driver, and uninstalling/reinstalling it. I have been using Windows Update to make sure my computer is up to date. When I try to search for solutions, I feel that at this point most of what comes up is eith

  3. Second monitor not detected

    Hello,

    May we know if you've already tried the suggestion provided by Robert Aldwinckle on forums on this

    thread
    ?

    If Windows can't detect your second monitor, it's usually a driver problem. It could be due to your video driver being outdated, incorrect or faulty. It's also possible that your monitor driver is causing the problem.

    Since the issue occurred after the latest update, it's possible that the video or monitor drivers require an update. Try looking for the updated version of the drivers on the device manufacturer's website and follow their instructions.

    If the issue persists, try to roll back the drivers to the last good configuration. To do that, you may follow these steps:

    • Right-click the Start button and select Device Manager.
    • Right-click your device driver, select Properties, and browse to the
      Driver tab.
    • Press the Roll Back Driver option if available, and Windows 10 will begin the process.

    Let us know how it turns out.
