    external monitor not found after update


    My laptop updated on 8/13/2020. After the update my HDMI monitor no longer connected to the laptop. I have tried to use "detect" but the laptop just doesn't seem to be able to find the monitor. I have follow all the steps, changed out the HDMI cord, switched ports to no avail.

    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.
