  1. External Display Not detected Error code 43


    Hi,


    My laptop is not detecting any external monitors attached to my HDMI port. In Device manager I see the display adapter has a warning triangle on it, and in the properties I see the error message:


    "Windows has stopped this device because it has reported problems. Code 43"


    I've tried reinstalling drivers including to a previous version but the problem still persists. Any suggestions would be appreciated!


    OS = Win 10 64bit

    Graphics card = NVIDIA GeForceGTX1060

    Nvidia driver = 451.48


    Thanks for your help!

    :)

  3. Display adapters giving error code 43 and & unknown device.

    Hi,

    You may get Error Code 43 when the device driver notifies Windows that the device has failed. This usually happens if the device hardware fails or if the device driver itself fails. To help you with this issue, we suggest that you perform the
    troubleshooting steps found on this link. The link will
    provide you steps such as how to roll back the driver or how to uninstall and check for hardware changes.

    For any results, just send us a reply.

    Hi 孔孔, my name is Max and I'm an independent advisor.

    The error code 43 means that either the device drivers or the device itself has an issue.

    I suggest you refer to the support article:

    If the above mentioned steps don’t help, please contact your device manufacturer for further assistance.
