    Surface Laptop 3 with external monitor


    Hi All,

    Has anyone come across an issue with an external monitor blacking out while connected to a Surface Laptop 3? I have the laptop connected to a widescreen laptop with the Surface Dock. Both work fine however, once every hour or so the external monitor blacks out and comes back.

    I've completed the following:

    • Updated laptop drivers and firmware
      • Updated monitor drivers
      • Swapped out monitor
    [/LIST]

    :)

    Surface 3 / Win 10 Not Recognising External Monitor

    I have a relatively new Surface3, recently upgraded to Win 10. I have since purchased a BenQ LCD monitor (model EW2440).

    Connection is miniDP on Surface 3 to HDMI on BenQ. I have a short MiniDP to HDMI adapter(F), then HDMI (M-M) cable to the monitor.



    On connecting the monitor to the Surface, the monitor reports “HDMI no signal” and the Surface (Win 10) does not react to the presence of the device at all. (If I remove the HDMI cable, monitor says “No cable connected” - so it at least knows the
    HDMI cable is plugged in).



    I've verified the Monitor is not defective by plugging it in to a Win7 Laptop equipped with HDMI. Works fine.

    ALSO – I can connect the Surface to a HDMI input on my TV and that works fine. Suggests communication via HDMI from Surface, and the cables, are OK.



    It is just when the Surface connects to the BenQ that neither device appears to “see” the other.

    I verified that the Graphics adapter/driver is the latest provided by Microsoft. (Intel has a later drive but does not recommend replacing the custom MS variant of the driver.)

    What could be the problem?

    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.
