  1. After recent Windows 10 updates, my external monitor no longer works


    I have 2 old laptops, using VGA to HDMI converter. Both worked fine before the update but now there is no signal coming from VGA port on either one. I've updated video drivers (and tried older drivers but it doesn't seem like they were updated with the Windows update), changed cables and made sure the external monitor (a TV) was working from another computer. Converter device is working properly, tested from another computer that hasn't been upgraded.


    Thanks in advance for your advice.

    :)

    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.

    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.

    Windows 10 - External Monitor No Longer Working

    I upgraded my Lenovo Yoga 2 Pro last week without issue to Windows 10 (yay!). Today upon shutting down and restarting my machine between meetings, the external connection to my monitor no longer is working and the USB3 connection for touchscreen on the
    external monitor is no longer recognized. Nothing had changed on my machine from between when it was working and now. I tried re-installing the latest display drivers for Windows 10 on Lenovo's website and there is no change. I uninstalled the display driver
    hardware in Device Manager and refreshed it without success. What's going on?
