If your Motherboard’s HDMI port has stopped working, don’t worry. There are many ways to fix the problem.

The motherboard is crucial for the smooth functioning of a PC, and the HDMI port present in it helps connect the board with the monitor beside the DVI (Digital Video Interface). A PC’s motherboard consists of different components such as the CPU and GPU.

So, you should be careful how you install it as it could cause all the components to malfunction if fitted in the wrong way.

However, if you find that the HDMI port is not working the way it should, or worse, not working at all, then you may need to resolve the issue immediately.

Now, there are many workarounds for this problem. Let’s see what they are and how to fix common motherboard HDMI port issues.

Motherboard HDMI Port Not Working: Common Problems

HDMI or High-Definition Multimedia Interface allows audio and video signals from a compliant device to the monitor. All PCs have a dedicated port on the motherboard that helps transmit signals to the monitor.

So, if this Motherboard HDMI port doesn’t function right, it will not transfer audio and video signals or transmit incorrect ones, and your monitor doesn’t show you anything.

What this means is that any problem with this port can render the monitor useless.

Some common reasons for this could be damage caused to the port or that the motherboard HDMI port could be disabled.

So, before you fix the problem, you must know the cause.

If you are using an old PC, the chances are that the different parts, including those on the motherboard, could be damaged.

So, check for broken parts or those that may be malfunctioning due to overheating. If you find that the HDMI port is damaged or broken, you may need to consider replacing it.

However, if that isn’t the case, you must continue to identify the problem.

Disabled Motherboard HDMI Port

Some manufacturers that sell motherboards with discrete GPUs may choose to disable the integrated graphics.

This problem mainly occurs in older PCs that have dedicated video ports where you can install the GPUs.

So, this means that in older PCs, the graphics cards sit in dedicated video ports, which is why the manufacturers would have disabled the motherboard HDMI port.

In that case, you will need to enable the motherboard HDMI by going into the BIOS settings.

Motherboard HDMI Not Working: Troubleshooting

When you have dedicated graphics installed on your motherboard, you should ensure that you connect all the display units to it.

However, if your video outputs are coming from the motherboard HDMI port and are disabled, you can follow these steps to re-enable them.

Check Your Integrated Graphics

Check Your Integrated Graphics

To enable the HDMI port present on your PC’s motherboard, the first thing you must do is check if your CPU has integrated graphics. If you want to check whether your PC has integrated graphics:

  1. Click on ‘Start‘ and open ‘Settings.’
  2. In the ‘Settings‘ menu, find and click ‘System‘ and select ‘About.’

Here, you should find details about your PC, such as the CPU and GPU. Note that you can also do this by following an alternative method. On your Windows PC, right-click on ‘This PC‘ and select ‘Properties.’ As soon as you click on ‘Properties,’ a window pops up showing the properties of your PC, such as the CPU GPU, Windows version, and more.

Another way to check the GPU your PC has would be through the ‘Device Manager.’ To do this:

  1. Click ‘Start‘ and type ‘Device Manager.’
  2. You should see an option called ‘Device Manager.’ Click on it.
  3. Expand the ‘Display adapters‘ option.

Once you expand ‘Display adapters,’ you should be able to see all the graphics cards installed on your system, including the integrated ones, if your PC has them.

Enable Integrated Graphics in BIOS

  1. After you have confirmed that your PC has integrated graphics, you will need to enable them. To enable integrated graphics on your PC:
  2. Access your BIOS by restarting your PC and pressing the relevant key as soon as it boots up. To access the BIOS, standard keys that you can use include ‘Escape,’ ‘Delete,’ ‘F1,’ ‘F2,’ and ‘F8.’
  3. Once you access the BIOS, navigate to the ‘Advanced’ tab.
  4. Now, in the ‘Advanced‘ section, find the option related to the IGPU multiple displays.
  5. Check to see if it is enabled. If not, you can enable it by clicking on the drop-down menu and selecting ‘Enabled.’
  6. Press ‘Enter’ to save the changes you made and restart your computer.

Connect the Monitor

The next step is to connect the monitor to the motherboard HDMI port. To do this, you must:

  1. Plug your monitor with the help of an HDMI cable to the motherboard HDMI port that you can find behind your PC enclosing.
  2. Similarly, plugin the other end of the HDMI cord to the dedicated port on your monitor.
  3. After you do this, boot your computer, and it should detect the monitor.

You can also change the display settings as per your requirements. To do this:

  1. Right-click on a space on the desktop of your Windows PC and select ‘Display Settings.’
  2. The ‘Display Settings‘ menu should open.
  3. Here, you can adjust different settings at your convenience.

Install the Latest Drivers

If your monitor is still not detected by your PC, then your graphics drivers may be outdated. In that case, you must update them. To update your graphics drivers:

  1. Click ‘Start‘ and type ‘Device Manager‘ into the search field.
  2. Click on the ‘Device Manager‘ option.
  3. In ‘Device Manager,’ navigate to the ‘Other Devices‘ section, and look for an option called ‘unidentified devices.’
  4. Right-click on an ‘unidentified device’ and select the ‘Update Drivers‘ option.
  5. After you select ‘Update Drivers,’ choose the ‘Find Drivers Automatically‘ option, and Windows should search for and install the latest drivers.
  6. Restart your computer to finish updating your graphics drivers.

Alternatively, you can also update your graphics drivers using the Windows Update feature. To do this:

  1. Click on ‘Start‘ and type ‘Windows Update‘ into the search field.
  2. Click on the ‘Windows Update‘ option to access the Windows Update menu.
  3. Once there, click on the ‘Check for updates’ option, and Windows should automatically check for and install all the latest recommended updates, including the graphics drivers.

Why Should You Enable Motherboard HDMI?

You have several advantages of enabling the motherboard HDMI, the primary one being that it allows you to connect multiple displays or monitors to your PC. Most motherboards, especially the older ones, come with only one HDMI port. So, technically, you can connect only one monitor to your PC unless you have a custom GPU installed.

However, if you have an old GPU, or a damaged one, you can always use the motherboard HDMI port to connect your PC to a monitor or external display.

Motherboard HDMI Not Working: How To Avoid The Problem?

If the HDMI port on your motherboard is not working or is damaged, you might want to consider replacing it to avoid display problems on your PC.

You should replace the motherboard HDMI, especially if you have been using it for quite some time.

However, if you are using a new motherboard, you should still check if all the components are working correctly to avoid problems in the future.

If the problem persists, you could also try using another HDMI port if your PC has one.

Using The Motherboard HDMI Port And Graphics Card Together

You can use both the Motherboard HDMI port and graphics card, but only if you connect more than two monitors or displays.

Most modern motherboards and graphics cards come with at least two ports. So, this means that you can connect four displays or monitors at once.

However, before you try this, you must check to ensure that your graphics card supports multiple displays.

Another thing you could do is connect your PC to your TV. Most TVs today come with at least one HDMI port. So, you can use them as a monitor or external display.

Final Thoughts

If you face display issues on your PC due to the motherboard HDMI port malfunction, you can use some troubleshooting tips listed above to resolve the problem. The solution to this problem could even be as simple as unplugging the cords and plugging them back.

However, if that doesn’t resolve the issue, you can always use other troubleshooting tips that you can find in this guide.

For instance, you could turn it back on by accessing the BIOS if the manufacturer has turned it off, or you could even install the latest graphics drivers using any of the methods given above.

Remember that you need to get the motherboard HDMI port to work to connect and work with multiple monitors or displays. However, it shouldn’t be a problem if there are enough ports to connect as many monitors or displays as you want.

The quality of the displays is another cause for concern. Sometimes, damaged motherboard HDMI ports may work, but the monitors may not display correctly. If so, you can try updating your drivers or replacing your motherboard HDMI port.
