Although a graphics card is an important component of a computer since it allows users to connect to external displays. Yet, many computer users have complained about the graphic card HDMI port not working. Some of the complaints include “GPU stopped producing signal HDMI”, “Why is my GPU saying no signal when my HDMI is plugged into it?”, “HDMI port stopped working, and how I solved it” and “HDMI Port on GPU not working with Monitor.

However, to resolve the graphic card HDMI not working on the computer trouble, you have to first determine the reason for it. As a result, we have put together a list of common causes for issues, and simple troubleshooting solutions.

Part 1: Common Causes of Graphic Card HDMI Not Working

Many people encounter problems with their graphic card HDMI not working when using external monitors or TV displays. It could be due to hardware faults or software bugs. Identifying the most common causes will help you troubleshoot and fix the issue successfully.

Here are some of the common reasons for graphic card HDMI malfunction:

1. Faulty HDMI Port: One of the common reasons for graphics card HDMI port not working is related to hardware issues, specifically a faulty HDMI port. With prolonged connect and disconnect action, often HDMI ports tend to get damaged and come loose.
2. Outdated Graphics Card Drivers: Outdated or incompatible graphics card drivers are another common cause of HDMI ports not working. These drivers act as a connection between the graphics card and the operating system for smooth working. If they are outdated or do not match the hardware and software, they can cause many kinds of issues, including HDMI port failures.
3. Display Settings and Resolution: Sometimes, the HDMI port functioning could be impacted by incorrect resolution and display settings of your computer. Check the display settings to ensure they are properly configured. Some graphics cards require specific DisplayPort specifications for higher refresh rates or resolutions. Incompatible settings or unsupported DisplayPort configurations can lead to HDMI port malfunctions.
4. Physical Connection Issues: Not many users realize it, but the most common cause of an HDMI graphics card not working is a physical connection issue. A loose or damaged cable might distort the signal, preventing correct display output.

If your graphics card HDMI port is not working, there are many troubleshooting solutions you can try. Since different factors can cause this problem, so there are specific methods to fix each issue. Try each solution one by one and see which one resolves the problem for you.

Method 1: Check for Windows Update

Many computer-related issues can be resolved by updating the Windows operating system to the latest available version, including the HDMI graphics card not working issue. While the most recent update not only fixes any bugs in the OS but also upgrades the set of features on the system.

Here are the steps for updating your Windows system:

Step 1: Launch the “Settings” window from the “Start” menu and select “Update & Security”.

Step 2: Select the “Windows Update” option on the left side panel and click the “Check for Updates” option.

Step 3: Wait until Windows searches for available updates. If you see any latest updates to the system, click on the “Download & Install” option next to it.

Step 4: Once the installation of the update is over. Restart your system when prompted.

After the system restarts, try connecting your display device to the graphic card HDMI port and check if the issue is resolved.

Method 2: Try a Different HDMI Cable

As noted earlier, a faulty HDMI cable is among the common causes of graphics card HDMI not working issues, resulting in physical connection problems.

You can try using a different HDMI cable to rule out any cable-related problems. Inspect that the cable is in excellent condition and is securely connected to both the graphics card and the display device.

Method 3: Test the Device with a Different Display

What if the issue is not with the graphics card HDMI port at all? It is important to make sure that the issues lie with the graphics card, HDMI cable, or the display device itself to figure out why HDMI not working on graphics card.

You can try connecting the graphics card to a different display device, such as a different monitor or TV. In case the HDMI port works with a different display, it means that the original display you were having issues with is the problem.

Method 4: Update Firmware and BIOS

Sometimes, outdated system firmware or BIOS on your graphics card can also result in compatibility issues and affect HDMI port functionality. You can update firmware or BIOS for your graphics card by visiting the official website of the manufacturer and checking for available updates for the particular model. In case you find the relevant updates for your graphics card model, follow the instructions provided by the manufacturer to update the firmware or BIOS.

Note: However, it is important to note that updating firmware or BIOS carries some risks. So, it is vital to follow the instructions from the manufacturer and back up your system data before starting the process.

Method 5: Check for Overheating

As with any hardware component, overheating is one of the primary reasons for malfunctions, and the same with the graphic card HDMI ports on your system. When the HDMI port is under constant usage, resulting in excessive heating, it can damage the port and cause connectivity problems. You must constantly ensure the graphics card is sufficiently cooled and the fans are working efficiently. Avoiding overheating is crucial for the HDMI port and other components to function at their best.

Additionally, check there is no dust or debris gathered on the graphics card or cooling system, causing not enough cooling issues. Your system should have good ventilation, and if you think it is overheating, then consider implementing extra cooling measures such as additional fans or a liquid cooling system.
