  3. Lenovo Flex 2-15 Windows 10. Stopped detecting second monitor

    Hi,

    I realize that the computer is not detecting the second monitor. I will try to help you with this issue.

    Please answer these questions to get more clarity on this issue:


    • Does the second monitor support touch screen feature?

    • Have you updated the Touch pad driver on the main PC?

    • Have you installed all the pending updates on the computer?
    Suggest you to plug in the monitor and run the hardware troubleshooter. Once this is done, restart the computer to check if this helps.


    • Press “Windows key + X” to click on “Control Panel”.

    • Click on “Troubleshooting” and click on “View all”.
    Click on “Hardware and Devices” to run the troubleshooter. Once this is done, restart the computer and check if this helps.

    Keep us informed to help you further.

    Thank you.

    windows Can't detect my second monitor

    Hi Max,

    Thank you for posting your query in Microsoft Community.

    I understand that you are having a tough time working on the computer.

    I will certainly help you to resolve the issue.


    • What happens when you try to connect the second monitor?

    • Do you receive any error code/message?

    • Have you tried to connect the second monitor on a different port?
    I suggest you to connect second display using a different port available on your PC and check if the second display works. If second display works in other port, then the possible cause for this issue may be discrete video card driver.


    Let us try the following steps, and check it helps.

    Step 1: Run the Hardware and Devices
    troubleshooter.

    Hardware and Devices troubleshooter checks for common problems and makes sure that any new device or hardware connected to your PC is installed correctly.


    • Type troubleshooting in the search bar.

    • Select Troubleshooting.

    • Select View all on the top left corner.

    • Click on Hardware and Devices.

    • Follow the on-screen instructions to run the troubleshooter.
    Step 2: Update the Display Adapter.


    • Press Windows key + X and click on
      Device Manager.

    • Expand Display Adapter.

    • Right click on the video driver and select
      Update Driver Software.

    • Restart the computer.
