    How to stop automatic duplicate/extend displays


    Hello all! I'm using my Windows 10 laptop with a secondary external monitor which i want to use as a display, without the laptop's built-in display. The problem is, despite i set to show the image only on the secondary (external) monitor, after each restart or after i close the laptop's lid, it reverts to duplicating the image (or extends it, if select extend inside of duplicate). How can i stop this?? I have to manually reselect to show the image on the 2nd display only. Thanks!

    extended display windows 10

    Hi Marg,

    It is possible that your extended display was not detected after an update due to having incompatible display drivers. To efficiently assist you, we'd like to gather more information:

    • Which build and version of Windows 10 are you using?
    • Are you getting any error messages?
    • Could you tell us what troubleshooting steps have you done so far?

    We're looking forward to your response.
