    Windows 10 HDMI port not working


    Today my hdmi stopped working after a windows update my laptop is Dell Latitude 7490, I did a lot of research and couldn't find a good solution for it. I updated all drivers and nothing. So I finally updated the firmware and guess what, it worked!.

    My question is, why Microsoft didnt warn you about it.

    Go to Settings -> windows update -> optional updates and choose firmware if it is in the list. Maybe there is another one for you that will fix it.


    I post this here because I was not able to answer a previous question. Hope this helps someone else.

    :)

  2. HDMI Port Stopped Working

    I generally use a second monitor via an HDMI cable while working. However, it stopped working today.

    I checked these:

    • Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.
    • HDMI cable which I use works if another device is connected to the second monitor.
    • My computer detects my HDMI-to-VGA converter through HDMI port.

    My computer runs Windows 10 Home with latest updates installed.

    I suspect this is due to a driver error. How can I fix this problem?

    HDMI port not working

    I have an HP Elitebook running Windows 10 Pro version 10.0.18362 Build 18362

    I have been installing the system updates and now my HDMI port isn't working and I cannot connect an external monitor. I have followed a few posts and have gone and re-installed my Intel display drivers and it has not solved the problem. Well, what I did
    was install an Intel app to check my system and it had me update 2 different drivers. I did not uninstall and then reinstall my display driver.

    I really need that external monitor. Would love some workable suggestions on how to get my HDMI port working again.

    Thanks
