HDMI Port is not Working on PC: 7 Ways to Fix it

You must have encountered a problem that has led to your HDMI port not working on Windows 10. This is a problem other users have experienced.

This port is handy for connectivity, especially with modern equipment, so we will show you how to fix this problem.

Why is my HDMI port not working on my PC?

There are multiple reasons why the HDMI port isn’t working on Windows, and in most cases, this is just a glitch with your graphics card, so you might want to check your drivers.

This issue can affect any PC, and many reported that HDMI isn’t working on laptops. If drivers aren’t the issue, a solid workaround would be to use a specialized adapter.

However, that’s not always the best solution since sometimes the USB to HDMI adapter won’t work, so it’s essential to find the core cause of this issue.

Here are some quick examples of how these issues can manifest:

• HDMI won’t work on a laptop – In most cases, the TV fails to recognize your laptop.
• The HDMI audio won’t play – Oftentimes, the video is available, but the audio won’t play.
• HDMI image is too big for the screen – Fortunately, installing the latest graphics driver updates should fix this problem within minutes.
• HDMI video is choppy – This usually happens when a second monitor is connected via HDMI.

The most common problem with HDMI is that audio or video is missing, and in most cases, that’s caused by driver incompatibility, but there are a few things you can do to fix this problem.

How do I test my HDMI port?

1. Check for damage along the length of the chord.
2. Check for particles in the head of the chord and the port on the device. You can spray some compressed air to remove these particles.
3. Insert one end of the chord in the source device and the other in the display device.
4. Boot the display device and ensure it is set to HDMI mode.
5. Boot your source device and ensure it is set to export images.
6. If the image and sound quality are fine, nothing is wrong with your HDMI chord.

If there’s no sound, video is missing, or your HDMI port is not working on your PC, follow the below steps to refresh your audio and video drivers.
