    PC does not recognize my second monitor, and only mirrors my first monitor.


    I have two monitors connected to my PC, one connected via HDMI and one via VGA. In display settings it is unable to detect my second monitor. The image on the second monitor is only mirroring the image on my first monitor.

    How can I fix this?

    windows not recognizing second monitor

    Hello,

    Windows may not recognize another external display device if the display drivers are outdated, or that the monitor is turned off or not plugged in correctly, etc. For us to isolate the issue in connecting a second monitor in Windows 10, kindly respond to
    the questions below:

    • Have you made any significant changes to your device prior to the issue?
    • Did the second monitor work before?
    • Have you tried using the monitor to a different computer?
    • What happens if you disconnect your primary monitor and connect the second monitor to make it the main monitor?

    We look forward to your response.

    Multiple mirrored monitors

    I am trying to have the screen and programs on my desktop mirror on a second monitor and a projector. How do I do this in Windows 10? I have connected all 3 to the desktop and the background on the main monitor shows on the 2nd monitor and projector,
    but I can't get the apps or programs to show on either the 2nd monitor or projector. I ran a test and the system recognizes the main monitor as 1, the 2nd monitor as 2 and the projector as 3, but then I can't get 2 and 3 to show anything I am doing on 1.
    Any thoughts?

    PC does not recognize my second monitor, and only mirrors my first monitor.

    Windows 10 will not detect second monitor and just mirrors the display

    Hi

    My son has a gaming pc with a new NVidia video card and running Windows 10 I believe and we have just purchased an ultra wide gaming monitor for his birthday.

    He wishes to keep his AOC existing monitor and have 2 monitors up and running and to extend the display and not mirror.

    We have connected both via HDMI using I think the term is a HDMI splitter purchased from Amazon.

    We have updated the Nvidia drivers as suggested and ensured all the cables are connected but when we go to Settings and additional display it does not detect the second monitor and the display is mirrored with no option to extend.

    Searched on the web for half a day with no real suggestions. I use 2 monitors at work without issue so cannot explain to him why it will not detect the 2nd display.

    Any help would be greatly appreciated. Thanks.
