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
How to Fix HDMI not working on PC/Laptop Issue?
We’ve shared some quick fixes and troubleshooting methods below to fix the issue.

Second Screen Only – This option helps you show content on the Secondary Display.
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
Graphic device drivers play a major role in displaying content on your system. Any problem with the graphic drivers may not only cause HDMI not working on PC or laptop error but also cause multiple system errors, including:
- New Hard Drive Not Showing Up

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:

- 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.
