  1. Windows 10/External Monitor Issue


    So I have my gaming laptop hooked up to a external monitor and that is my main monitor, I have no intention to use the laptop monitor anymore. However, I do need to keep my laptop screen open slightly so that the air vents can function optimally. I originally had the laptop closed and it only detected my External preferred option. Now, for the air vents, the laptop is slightly open and I have both displays showing on Display settings but does this affect performance at all on my system? For now, I know how to make the External monitor display only and manually turn off the laptop one in Settings, but is there a way to make Windows think that the only display connected is my External? Silly question I know, but I just don't want my laptop running harder if the screen is slightly ajar.

    :)

    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.

    http://answers.microsoft.com/en-us/...ndows-10/a97bbbd1-9973-4d66-9a5b-291300006293

    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

    Troubleshoot external monitor connections in Windows 10


    Set up dual monitors on Windows 10



    Let us know how it goes.

    Regards,

    Vivian S
