  1. Only works with external monitor


    So my windows 10 laptop uses internal monitor when in safe mode and splash screens, but when widows loads it only sends it to second monitor. I have only use built in lcd selected in bios and tried to disable graphics drivers in safe mode then reboot to no avail. Also installed most recent Intel built in graphics drivers. Don't know what else to do. Any suggestions?

    External monitor blanking often

    Hi,

    Please answer these questions to assist you better.

    • What is the make and model of your computer and external monitor?
    • Have you installed all pending Windows and driver updates?
    • Do you get any error message?

    I suggest you to install all pending Windows updates in your PC and also update Display drivers. Follow the steps below.

    Step 1: I would suggest you to check and install any latest Windows Updates available.

    • Go to Start and then Settings.
    • Click on Update and Recovery.
    • Check for updates under
      Windows Updates.
    • Restart the system and check if the issue is resolved.

    Step 2: Please refer to the following Wiki article created by
    Andre Da Costa on How to: Install and Update drivers in Windows 10.

    How to: Install and Update Hardware Drivers in Windows 10

    Do let us know if you still get random black screen in the external monitor. Thank you.

    External Monitor with Quicken

    Hi Mark,

    It is possible that the display resolution automatically adjusts after connecting to an external monitor. For us to properly isolate this issue, we have some questions for you:

    • Are you experiencing the same issue even without using the Quicken tool?
    • Have you checked if the display resolution settings of the Surface device and the external monitor is the same?
    • Have you tried checking for a graphics device driver update?
    • What troubleshooting steps have you done to isolate the issue?

    We're looking forward to your response.

    External monitor display settings

    Hi,



    Thank you for posting in Microsoft Community.



    I understand that you are facing issues with the display scaling on your external displays. We will certainly look into this for you.

    As you are using Vizio TV, you may have to try using custom resolution settings if the in-built settings do not provide the required settings.

    For better clarity, please let us know:

    • What is the version of Windows 10 that is currently installed on your computer? You can click on Search and type
      winver.
    • Are you aware of any recent changes to the system, such as updates, after which you are facing this issue?
    • What is the make and model of your computer?


    Meanwhile, I would suggest you to check the steps mentioned in the Workaround section in

    Windows scaling issues for high-DPI devices


    I would also suggest you to check the Display drivers. Please refer

    Set up dual monitors on Windows 10



    Let us know how it goes.

    Regards,
