    Laptop no longer recognizes an external monitor.


    Hello, I am having a very weird issue with my external monitor, a LG Ultragear 27GR93U-B.Received a new monitor today because I’m planning to build a game pc. But since I have not yet purchased all components and I still wanted to view the monitor, I decided to connect my laptop via an HDMI cable.This also went well at first and I experienced no problems in 4k & 60hz.However, when I adjusted the screen resolution to 2560 × 1440 and the refresh rate to 144hz, problems arose. The monitor went black and now my laptop no longer recognizes the LG Ultragear 27GR93U-B, nor can I change the settin

    Laptop suddenly stopped recognizing the external monitor

    Hi,

    Thank you for posting your query in Microsoft Community.

    To assist you better, I would like to ask if the laptop is unable to recognize only the external monitor or other external devices also.

    I suggest you to run the Hardware and Devices troubleshooter by following the steps below:

    • Click on the Start button, and type “Troubleshooting” on the search bar.
    • Click on “Hardware and Devices”.
    • A pop-up will appear, click on the “Next” button and your hardware troubleshooting will start.

    Hope the information is helpful. Keep us posted on the status for further assistance.

    Laptop no longer recognizes an external monitor.

    No display on laptop's external monitor-Monitor recognized but blank

    After the recent Windows 10 update, my wife's laptop no longer displays on the external monitor. All was well before the update.

    I am comfortable that Windows sees the monitor because clicking on Display Settings shows two displays. If I unplug the HDMI cable, only one display is shown.

    I have confirmed that the monitor works by trying it with another laptop. I have also changed the HDMI cable between the laptop and the external monitor.

    Device manager reports that I have the latest display driver installed.

    I would appreciate any and all suggestions.
