The HDMI (High-Definition Multimedia Interface) port, which enables users to connect their PCs to high-definition displays, has become an essential component of modern computing. But there can be times when the HDMI port is not working on the PC, which can be caused due to different reasons. 

Method Difficulty Rating

Scan For Hardware Changes

You can do a manual scan to look for the devices you have recently plugged into your system by checking for hardware changes. You can also reinstall display adapters as per users online. Here is how to scan for hardware changes:

1. Remove Glitches: Go to Device Manager > Open the Action tab > select Scan for Hardware Changes > If the Monitors section has the device you are using for display, restart your PC first to make it work again and remove any temporary glitches.

   

2. Modify Display Settings: Press Windows+P to start, and you’ll have several options > Start selecting options one by one until a picture displays.

   

Update GPU And Motherboard Drivers

Some monitors may only properly show content if you have an updated GPU driver. Updated GPU drivers can help prevent HDMI malfunctioning. First and foremost, download the latest updates of NVIDIA GeForce Experience or AMD’s drivers from their official site and install them.

The second alternative is a manual update of the drivers. Taking this step worked for us and also for users on the Microsoft forum. Here is how to do so:

1. Access Command Prompt: Open Device Manager > Hardware and Devices Troubleshooter > Type CMD into the search field by hitting the Windows key.
2. Enter Command: Type msdt.exe -id DeviceDiagnostic in the command prompt and hit Enter.

   

3. Repair PC: Check on the Apply repairs automatically under the Advanced tab > Once the troubleshooter finishes repairing, click Next and proceed > Restart PC and check HDMI.

Uninstall The Graphics Driver

Damaged graphics drivers can disrupt the communication between the operating system and the graphics hardware, potentially leading to various issues, including the HDMI port not working.

Additionally, outdated or incompatible graphics drivers can exacerbate these issues, further impairing the functionality of the HDMI port. Uninstalling the graphics drivers solved the issue for us. Here is how to do so:

1. Uninstall Driver: Launch Device Manager > Display Adapter > In the menu, look for your graphics and right-click on it > Select Uninstall Device.

   

   

Run Windows In Safe Mode

When Windows is started in safe mode, all settings and apps are forced to operate at their default settings. The safe mode could fix any corrupted data about the HDMI controllers. Taking this step solved the issue for us. Here’s how to run Windows in safe mode:

1. Access Boot Tab: Go to the command prompt through the Windows start menu > Enter msconfig command in it > Now go to the Boot tab and its settings > Untick the Safe Mode checkbox from the menu that appears.

   

2. Check HDMI: Once Windows restarts in safe mode, test if your external device is correctly identified. Try replugging the HDMI cable to make it work on a PC.

Remove Recently Installed Software

This fix might be effective if the HDMI port does not appear in your Device Manager. Recently installed software can sometimes cause compatibility problems and connection issues. These instructions will help you delete recent installations:

1. Uninstall Program: Access your PC’s Control Panel > Jump to Uninstall a program > Look for the software you recently installed > Click the Uninstall option on it > Do the same for all new installations unless the HDMI port starts working.

Run System Restore

The system restores option enables you to return to some of the old efficient configuration settings without losing files which might as well make the HDMI port work.

1. System Restore: Type restore into the Windows search box > Create a restore point > It will then display the System Properties panel > Select System Restore from the menu.

   

2. Select Preferred Restore Point: Click Next once the System Restore window has opened > Select Show additional restore points if they are available > From the menu, choose the preferred restore point, then click Next > Follow on-screen steps.

   

Conclusion

We have learned that the HDMI port will only work if the cable or its head is fixed, the PC’s drivers are updated, or any compatibility issues. Try not to give in to frustration if an HDMI port on your PC isn’t working. Users all around tend to hate it when their HDMI port does not function.
