    Windows 11 home ----HDMI Port not working or listed in Device Manager -- after Windows Update disabled my AMD Adrenaline Graphics update and Chipset update.... that was downloaded and installed from the AMD website...but I did the "Rollback Driver" on the driver but still no HDMI working.....and device manager still doesn't list anything about HD Graphics in list.... just HD audio is listed ? How can I reinstall or recover my HDMI port ? .... or how would my HDMI be listed in Device Manager?

    Graphics card not working

    The hdmi port doesn’t show display and the graphics card is not detected in device manager. This started after I cleaned my pc.

    My HDMI Port is not working and my graphic card is neither showing in Dxdiag or task manager.

    display port to hdmi no signal


    Do you have the latest drivers installed for the graphics card?

    If new drivers or reloading graphics card drivers doesn't fix it, the next thing I would suggest is to try the display port to HDMI adapter a couple of us have suggested already with a regular HDMI cable. If your cable is bad or you just need an adapter because for some reason a straight cable won't work - spending $20 on the adapter is a lot cheaper than new graphics card. I just installed my GTX 970 card a week ago and I had plenty of HDMI cables so that is why I went with the adapter instead of buying a new display port to hdmi cable.
