  1. hdmi stopped working


    I THROUGHLY tested my cables, and they work fine with OTHER, known good computer. My HDMI stopped working this morning when i went to use it, but last night it was working fine...when i went to settings, the pc says it did not detect another monitor. what do i do?

  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?

    win10 HDMI worked then stopped working

    hi

    win 10 w ASUS P8Z77-M motherboard using on board video. very vanilla setup.

    after win10 upgrade, it took me a while to figure out I needed to update motherboard stuff but finally got HDMI monitor working.

    then today a giant step backwards.

    I plugged in a mini USB hub and now HDMI quit working under windows. It works fine when running diags initially but when it transitions to windows, no more HDMI signal. so unplugged usb hub but now no HDMI in windows. this blows. i appreciate it was my bad
    not to do all mobo upgrades prior to win10, but this is nuts.

    So i am open to suggestions on how to resolve this. I'm shocked HDMI would have stopped working in windows.

    THanks,

    Mike

    Hdmi sound not working

    Hi Peter,

    One possible reason why the HDMI sound does not work is due to the conflicts with the playback settings. For us to help you make the HDMI sound to work, we suggest that you answer the following questions for further research:

    • Have you made any recent changes to your computer?
    • What is the current build and version of your Windows 10?
    • Have you tried to download and install the most updated sound and display driver of your computer?

    Meanwhile, we suggest that you perform the steps on this
    article
    as our initial troubleshooting and see if there will be any changes on the HDMI sound.

    We'll be waiting for your response.
