(Fixed) HDMI Not Working on Windows 10

HDMI or High Definition Multimedia Interface includes two parts – (i) the port that establishes the connection and (ii) the connector cable that transmits the data. HDMI ports act as an all-digital interface that receives and transmits audio and video output signals between two devices.

Using these ports, you can project HQ videos and audios onto HD-capable devices, like TVs and audio receivers. Additionally, you can convert devices into a powerful multimedia hub using these ports. The ability to identify and communicate media and devices is called ‘HDMI handshake.’ But when this handshake faces any interruption, the HDMI port stops working, and you may encounter different problems, including:

• Television fails to recognize the laptop
• Video plays but there is no audio
• The image appears too big on the screen
• Video seems choppy

Why is HDMI not working on the Laptop/PC?

There are multiple reasons that may lead to problems with your HDMI port. However, the most common causes include:

• Incompatible or faulty drivers
• Corrupted registry
• Incompatible or corrupted apps installed on your system
• Temporary files and folders

The issue could occur due to a simple hardware problem. Check if your HDMI cable is in good condition and properly connected to both ends, i.e., Windows and HDMI devices.

Now, choose the appropriate option and see if it fixes the HDMI port not working on the laptop issue.

Method 4: Update, Roll Back, or Uninstall Graphic Drivers

• On the next prompt, go to the Action menu and click Scan for hardware changes > Reinstall driver.
• Once the driver is reinstalled, close the window and restart your system.
• Finally, check if the HDMI not working on the laptop/ PC issue has been resolved.

Method 5: Clean Temporary Files and Folders

The temporary and junk files stored on your system may affect your system’s processing speed, causing apps to respond very slowly and even sometimes may cause HDMI audio and video issues. To fix the problem, you can delete your temporary files and folders using Disk Cleanup. Follow the given steps:

• Else, you can open File Explorer, go to This PC.

• Now, click Disk Cleanup.

• Open Command Prompt (CMD) and run it as an administrator.
• In the elevated window, type SFC/scannow and press Enter.

• Wait until the process completes. Once done, close the window and reboot your system.

Method 7: Perform System Restore

If none of the methods helps resolve the error, you can perform a system restore. To run System Restore, follow the given steps:

• If your system is on, turn it off. Now, reboot it, and the moment it starts showing you the Windows logo, forcefully shut it down with the POWER button.
• Repeat this thrice. It will interrupt the normal booting process and take you to the Windows recovery environment – Windows Automatic Repair.
• On the Windows Automatic Repair screen, click Advanced options.
• Next, choose Troubleshoot and then go to Advanced options > System Restore.

• Click Next to proceed and choose a restore point from the available options.
• Click Scan for affected programs to check which system apps/programs are going to be affected due to this method.

• Click Next and then click Finish on the next prompt.
