5 Ways to Fix HDMI Not Working on Windows 10

1. Check the HDMI Cable Connection

It’s essential to examine the HDMI cable connection first because loose connections and defective cables are frequently the significant causes of HDMI malfunctions.

2. Run Hardware and Devices Troubleshooter

One helpful tool in Windows 10 is the pre-installed hardware and device troubleshooter, which may assist you in fixing various hardware-related problems, including this one.

 The troubleshooter will identify and fix the faulty hardware immediately. 

To use the troubleshooter, follow a few steps and give it time to finish. 

Using the search box at the bottom, use Cortana to open the command prompt.

 Enter cmd, then choose Run as Administrator from the menu when right-click the command prompt. 

There will be a pop-up window. Type “msdt.exe -id DeviceDiagnostic” in this line and press Enter. 

You’ll see a new window for troubleshooting devices and hardware.

 To let the software identify and resolve any problems you may be having, click next. 

To fix the HDMI port, you must adhere to the on-screen directions provided by the troubleshooter, which will automatically identify the hardware-related problem and offer a precise solution. 

3. Change Display Settings. 

If the Windows 10 troubleshooter fails to fix the problem, you might have to tweak your PC’s display settings when using two screens. 

To get the most out of your external monitor, it’s crucial to tweak a few display settings to fit your needs. 

If your computer’s HDMI connector isn’t functioning, try these steps to adjust the display settings.

Four choices will show up for you to choose from.

  • PC Screen Only: Just the first monitor will be used. 
  • Duplicate: This will make a copy of the content on both screens. 
  • Extend: This will make the content on both displays fill the entire screen.
  • Second Screen Only: Only the second screen will display content in this case.

Select the appropriate parameters based on your needs. 

To show content on the second screen, you’ll need to pick one of the last three choices.

4. Update or Reinstall your Graphics Driver

Update or Reinstall your Graphics Driver

An out-of-date graphics driver is one software-related problem that might cause the HDMI port to malfunction. 

Update your PC’s graphics driver and check whether the HDMI connection begins to function. 

It may surprise you to learn that outdated drivers are frequently the root cause of many Windows-related issues, and this is one of them. 

Go to Device Manager by pressing Windows X. 

Extend the choice for display drivers. You may now select the Update driver by right-clicking on your primary drivers.

 Select “Search automatically for drivers” at this point. 

To finish the driver download procedure, follow the on-screen directions to download them online. 

After the graphics driver update has been completed successfully, restart your computer and attempt to connect via HDMI.

5. Set HDMI Device as Default. 

Verify that the HDMI device you are using is set as the default. 

Most of the time, your Windows system will only function with your HDMI device if configured as the default device. 

This may be the cause of your inability to hear audio over the HDMI;

 Thus, you must make the HDMI device you want to use the default device by doing the following:

 Right-click the volume icon, select “Open Sound Settings,” and then press the “Sound Control Panel” button. 

Choose the preferred playback device under the playback tab and press the set default button.


Using the methods discussed, you can resolve the issue of your Windows 10 computer’s malfunctioning with HDMI.

 Remember that if none of these options successfully fix the problem, the HDMI port on your personal computer may be damaged. 

If this is the case, you must get it fixed by a trained specialist.
