How to Fix HDMI Port Not Working on Windows PC – 6 Methods

Plugged your PC into a monitor or TV via HDMI, but it displays a blank screen or a depressing “No Signal” message? You are not alone. HDMI connection failures are among the most frequent display issues on Windows, but it’s often not hard to fix.

Try the fixes below in order. You don’t have to try them all. Just start with the simple checks first, then move on to your computer settings and hardware troubleshooting.

1. Check Physical Connections
2. Select the Correct Display Mode in Windows
3. Restart and Reconnect Your Devices
4. Update Your Graphics Driver
5. Check Your HDMI Audio Output
6. Check for Hardware Problems

Before starting: check the display input

Before changing Windows settings, make sure the monitor or TV is actually set to the HDMI input you’re using.

Use the display’s physical buttons or remote to open its Input/Source menu, then select the correct HDMI port, such as HDMI 1 or HDMI 2.

If possible, also connect the PC to another HDMI port on the monitor or TV. This can quickly tell you whether the problem is with the PC, the display, or a specific HDMI port.

If you still don’t get a signal, continue with the fixes below.

Method 1: Check Physical Connections

A loose or damaged HDMI cable is one of the simplest causes of an HDMI connection problem. Before diving into any advanced troubleshooting, ensure that all physical connections are secure and functioning properly.

1. Shut down the PC and turn off the monitor or TV.
2. Disconnect the HDMI cable from both devices.
3. Check the cable for visible damage.
4. Reconnect the HDMI cable firmly at both ends.
5. If possible, try a different HDMI cable. If the PC or display has another HDMI port, try that port as well. If you’re using an HDMI adapter, dock, or converter, temporarily connect the display directly to the PC if possible.

After reconnecting everything, turn on the display and PC and check whether the HDMI connection works. If not, check out more fixes below.

Method 2: Select the Correct Display Mode in Windows

If you are using multiple monitors on your computer and you get an issue with your HDMI port, it might be happening because you’re using the wrong display setting. Check this setting on your computer and make sure you use the right settings to display your screen.

To check your computer display settings, press the Windows logo key and P on your keyboard at the same time. A list of display modes will appear.

The difference between each mode is as follows:

• PC screen/Computer only — Only using the first monitor.
• Duplicate — Displaying the same content on both monitors.
• Extend — Using both monitors to display an extended desktop.
• Second screen/Projector only — Only using the second monitor.

Select Duplicate or Extend and check whether the HDMI display appears.

You can also check whether Windows detects the display:

1. Right-click the desktop and select Display settings.
   
2. Scroll to Multiple displays. Click Detect if the HDMI-connected display isn’t listed.
   
3. If the display appears, select the appropriate display mode and resolution.

Method 3: Restart and Reconnect Your Devices

Sometimes restarting and reconnecting your devices is an effective method to get your HDMI port working again. Here’s what you need to do:

1. Disconnect the HDMI cable from the PC and the monitor or TV.
2. Shut down the PC and turn off the external display.
3. Unplug the power cables from the PC and display.
4. Wait for about one minute.
5. Reconnect the power cables.
6. Connect the HDMI cable firmly to both devices.
7. Turn on the monitor or TV first and select the correct HDMI input.
8. Start the PC.

Once Windows loads, follow Method 2 to select the correct display mode on your computer.

Method 4: Update Your Graphics Driver

Your graphics driver controls video output to external displays. An outdated, corrupted, or incompatible driver can therefore cause HDMI display problems. Try updating or reinstalling your graphics driver and see if this helps you resolve your problem.

There are mainly two ways you can update your graphics driver:

Option 1 – Download and Install the Driver Manually

Your graphics adapter manufacturer keeps updating drivers. To get them, you can go to its website, find the drivers corresponding to your specific Windows version (for example, Windows 11 64-bit), and download the driver manually.

Once you’ve downloaded the correct driver for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver.

Option 2 – Automatically Update the Graphics Driver

If you don’t have the time, patience or computer skills to update the graphics driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. Driver Easy handles it all.

Method 5: Check Your HDMI Audio Output

If you can see the picture through HDMI but there is no sound, the HDMI port itself may not be the problem. Windows may simply be sending audio to another playback device.

1. Right-click the speaker icon on the taskbar and select Sound settings.
   
2. Under Output, select your HDMI-connected monitor, TV, or other HDMI audio device.

Play some audio and check whether the sound works. If your HDMI device doesn’t appear as an available output device, move on to the next fix.

Method 6: Check for Hardware Problems

If none of the above methods resolve the issue, there might be physical damage to your HDMI port.

Check the following:

• HDMI cable: Try a known-good cable.
• PC HDMI port: Look for visible damage, bent components, or debris.
• Monitor/TV HDMI port: Test another HDMI input if available.
• Other display: Connect the PC to another monitor or TV to determine whether the original display is the problem.
• Other output: If your PC has DisplayPort, USB-C video output, or another supported display output, test it with a compatible display.

If another display works normally but the PC’s HDMI output consistently fails with multiple known-good cables and displays, the HDMI port or related graphics hardware may be faulty.

If you suspect physical damage, don’t try to bend pins or repair the HDMI port yourself. On a laptop or desktop motherboard, HDMI port replacement may require specialized equipment. Consider having the device inspected by a qualified technician.

We hope one of these methods helps you resolve the HDMI port issue. If you have any other suggestions or need further assistance, please feel free to leave a comment below.
