Windows 10: HDMI port is not working after an update on Windows

My HDMI port is not working after an update on Windows. The update was on May 11th. I have tried to update the driver but it doesn't help.

:)

 

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?

 

windows 11 home HDMI Port not working or listed how do I get HDMI working and find and reinstall HDMI Driver in Device Manager?

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?

 

HDMI port not installed. Recent updates may be the problem.

Hi GeraldParkhurst,

Thank you for writing to Microsoft Community Forums.

Could you please help me with the below information:

1. What is the make and model of the computer?
   
2. Which version of Windows you are using on both the computers? (To check, type: winver in start menu and hit enter.)
   
3. Do you see any error messages in device manager after connecting the HDMI cable?
   

This might have occurred due to some hardware conflicts or driver incompatibility issues. This happens if monitor isn’t getting any input from the currently selected source. To resolve this issue, I would suggest you to follow the
steps mentioned below.

Method 1: Update drivers.

1. Make sure that the cable are connected with correct ends, output port of the laptop and the input port of the TV/External
monitor are connected to the right port.

2. While the cable is connected
open device manager. The problem may occur by the faulty chipset drivers and graphics drivers. Try to update the drivers and check for the issue.

• • Press windows and R key together at the keyboard and type:
    devmgmt.msc
    
  • If you see any display drivers with yellow exclamation sign,
    Update the drivers.
    
  • Reboot the computer once and check.
    

Method 2: Change display settings.

1. Press Windows and P key on your keyboard together. You will see a Project option on the right side of the screen.
2. Select Duplicate or Extend (depends on your requirement) and check.
3. If it didn’t work, try to
   Change screen resolution and try step 1 and 2
   again.

Method 3: Disconnect and reconnect.

1. Unplug all the TV/monitor cables from the HDMI port.
   
2. Unplug the power cable of external monitor or TV for some time.
   
3. Plug the power cable back to the computer.
   
4. Plug in all the HDMI cables to the computer /TV.
   
5. Turn on the device and try Method 2.
   

Hope it helps.
