  2. Second monitor not detected after update

    Hi Tom,

    There are several reasons that could have caused the issue you are experiencing. One of these is the update you previously performed in Windows, either it was not configured properly by the system or the update components were corrupted. Kindly answer the
    following questions for clarification:

    • Have you tried updating the monitor and display drivers?
    • Have you tried to use another user profile to check if the issue re-occurs?

    Furthermore, we suggest that you add the other monitor manually. This is to ensure that the second monitor is still connected after the update. Here are the steps:

    • Type connected devices and open Connected Devices on the
      Windows Search bar.
    • Click Add devices.
    • Select the Second screen.
    • Pick one of the 3 options: Duplicate, Extend, and the Second screen only.
    • The Duplicate option will duplicate the primary display to secondary display.
    • The Extend option will unite two monitors so you can use them both as one.
    • The Second screen only option will, obviously, disable primary and use only the secondary monitor.
    • Once you’ve chosen the preferred mode, save changes.

    We're looking forward to your response.

  3. Second monitor screen resolution problem

    Hi,

    For us to properly isolate the issue with your second monitor screen resolution, we would like to know the following:


    • Were there any changes made on your computer prior to the issue (e.g., updates, software installation)?

    • When did the issue first begin?

    • To make sure that we have not missed on anything, what troubleshooting steps have you done so far?

    In the meantime, we suggest that you try resetting your monitor settings, and check if the issue still persists. You may refer to your monitor on how to reset it.

    We look forward to your response.

  4. 20H2 Update - can't find second monitor

    I accidentally hit the update button instead of postpone and now my second monitor does not work.

    Hello,

    I suggest you to unplug the cable from the monitor and connect to the second monitor, and check if it works.

    Also, suggest you to follow the below steps, and check if it helps.
    1. Press Windows + X, and select Device manager.
    2. Check if the second monitor is listed under Monitor.

    Also, recommend you to refer below link answered by

    KelvinNikkel , and check if it helps in resolving the issue.
