    External Monitor Not Working Via HDMI Cable


    Summary:


    After updating from 1703 to 1809 we are experiencing an issue where the external monitor has stopped working.


    The end user has an HP Elitebook x360 1030 G2 device connected to an external monitor via HDMI cable.


    The external monitor was working fine before the update.


    Troubleshooting steps we have tried:


    Check the cables are plugged in properly - all good

    Update Intel Graphics 620 driver - doesn't work

    Update the device BIOS to latest version - doesn't work


    Workaround:


    User is able to use external monitor by doing the following:


    - power on machine

    - at bitlocker, press esc twice which goes to bit locker recovery

    -power off the machine

    -power on

    -external monitor works


    However, has anyone come across this issue previously with a permanent fix?

    :)

    Samsung Monitor not working after Windows 10 install

    Hello,

    • Did you check if the external monitor work fine with other systems?
    To check if there is any issues with HDMI cable or external monitor, I suggest you to try connecting it to any other Laptop/Computer and check if this works fine.

    Kindly let us know the status to assist you further.

    Thank You.

    External Monitor Not Working Via HDMI Cable

    HDMI to VGA cable issue

    I have laptop ASUS S510UQR model installed windows 10.

    This laptop have HDMI port only so i use HDMI to VGA cable to connect to external monitor (projector) having VGA port.

    It works fine until i update windows 10.

    Normally, when i plug HDMI to VGA port to laptop, a sound will appear and i could see external monitor when i open Intel UHD graphic control panel.

    But now it does not happen.

    It works fine if i use HDMI to HDMI cable, meaning that the HDMI in laptop is OK.

    I use my HDMI to VGA cable for other laptop, it is OK (meaning that the HDMI to VGA cable is OK)

    I did try the following steps:

    - uninstall graphic driver and reinstall graphic driver using device manager.

    - Go to Asus website to download graphic driver and BIOS to update.

    - Finally reinstall a fresh windows 10

    This issue still happen.

    Could someone please help me to solve this problem?

    Thank you very much for your time.

    N.K. Quang
