    external monitors switch off randomly - possibly connected to Skype for Business usage?

    Hi Robert,

    It is possible that you're experiencing issues with your external monitors due to corrupted or outdated drivers. To assist you better, I'd like to gather more information:

    • Are you using the same device when connecting your laptop to your external monitors?
    • Have you tried updating your drivers?

    Meanwhile, if not, I suggest that you follow the steps in this article about updating drivers in Windows
    10.

    Let us know if you need further assistance.

    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.

    Windows 10 upgrade: can no longer connect to an external monitor

    Hi,

    Thank you for posting in Microsoft Community, we appreciate your interest in Windows 10.

    I understand the inconvenience you are facing with accessing the external monitor in Windows 10, we will help you with this issue.

    As you have tried most of the troubleshooting steps, let us know the following to assist you better:

    • What exactly happens when you try to connect to the external display?
    • Were you able to see the light on the external monitor (Tuned on/ not)?
    • Is there any error message with this issue?

    Step 1: As this may look very silly, I suggest you to check if the turned on or not, if it is on let us know the color of the light displayed.

    Step 2: I suggest you to remove all the external devices except mouse and keyboard and try to perform clean boot to check if there is any issue with the device and to avoid any third party software conflict.

    Disclaimer: Putting your system in
    Clean Boot     state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.

    How to perform a clean boot in Windows
