Nothing beats the feeling of going to an important meeting to present your work on PowerPoint when all of a sudden a faulty HDMI port gives you the gift of a black screen. 

The only way to see if your system recognizes your HDMI port is by checking if the device plugged into the HDMI port is properly functioning. To do this, look for these immediate signs:

  • The picture you get is distorted or glitching
  • There is no sound output
  • There is a black screen even though the Monitor is plugged in
  • The Cable is visibly damaged, loose or bent
  • The HDMI port is damaged, bent or scratched

If you notice any of these symptoms, it’s time to investigate and resolve the problem.

Why Is My HDMI Port Not Working on PC?

The common symptoms of a bad HDMI port are a lack of sound, image distortions or just no output at all. If the issue is hardware-related, the fix could be as simple as replacing the damaged cable. If there is software incompatibility, then in most cases updating your HDMI and GPU drivers will do the trick.

The following are the most common reasons you have issues with the HDMI port properly receiving and sending data.

  • There is an issue with the HDMI cable
  • There is an issue with your PC ports
  • The Monitor is faulty or not set up properly
  • You haven’t configured the PC to display a screen
  • There is an issue with your GPU / Motherboard drivers

To Check if Your HDMI Port Is Faulty on a Laptop

Laptops display HDMI ports under the device manager. If you see yours correctly listed there, there is no issue with your laptop recognizing the HDMI port. To check if this is the case, please perform these steps:

  • Go to the Windows Start Menu.
  • Type Device Manager in the search field.
  • In Device Manager, locate the tab Display Adapters.
  • Expand the tab by clicking on the arrow symbol.
  • Look, if an HDMI port is displayed, there.
  • If you see the HDMI port right, click it and press Properties.
  • Under properties, look for Device Status.
  • If it displays “The device is working properly”, there is nothing wrong with the HDMI port itself.

I use a desktop PC so that the HDMI port won’t show up. Still, the Device Status is displayed on another Communication Port. If you see this status for the port on your laptop, proceed further.

Below are all the necessary troubleshooting steps to resolve these potential causes that prevent your HDMI ports from working correctly. Go through the steps in the given order to fix your HDMI issue.

How to Fix an HDMI Port on Windows

Before you attempt any other troubleshooting steps, there is no point if the port itself is physically damaged or the HDMI cable is faulty. This is the correct way to check your HDMI port for physical damage:

  • Unplug the HDMI Cable and check if the middle section is bent, chipped or its conductive plating is scratched or removed.
  • Perform the same steps for the HDMI cable: Check if the connector part is loose, shaking or bent. If the cable is physically deformed, it’s not correctly transmitting data to your central Monitor – Replace it with another one.

After confirming that the HDMI port and Cables are in working order, proceed with the Software fixes:

Scan Your PC for Hardware Changes

The way to force your PC to scan for newly plugged in devices manually is to check for hardware changes in the Device Manager tab. Here are the steps:

  • Go to the Windows Start Menu
  • Type Device Manager in the search field
  • In Device Manager, locate the Action tab on top of the menu
  • Click on Scan for Hardware Changes
    Scan-for-hardware-changes

If you now see your display/ device correctly showing up in the Device Manager under “Monitors”, restart your PC to get the HDMI port to work correctly. 

Change the Display Settings on Your PC

This is perhaps the most effective troubleshooting step. The goal here is to force your PC to display your screen from the HDMI port correctly:

  • Press the Windows key + P
  • You will see the following menu appear.
  • Go through all the options until a picture appears on your Display that’s plugged into the HDMI port
    projecting-device

These settings tell your PC what configuration to display information on your Main Screen. If you have a laptop, make sure that Second screen only or Duplicate is enabled. 

Update Your Video Card/ Motherboard Drivers

update-graphics-driver

Having an outdated GPU driver can prevent the proper display output on some external monitors. Since the GPU’s in desktops also contain the physical HDMI output port, keeping their drivers up to date can prevent HDMI related issues.

Your first option for updating any GPU drivers is by installing and running either NVIDIA GeForce Experience or AMD’s equivalent. 

The second option is to force Windows to manually update them via accessing the Device Manager update function.

Run the Hardware and Devices Troubleshooter

This troubleshooter is useful as it forces windows to find and repair any possible issues with hardware components. It is already built in by default, but the way you access it is slightly different.

To open the hardware and Devices Troubleshooter you need to access it via the command prompt by manual input.

  • Press the windows key and type CMD in the search bar
  •  Type – “msdt.exe -id DeviceDiagnostic” and press Enter
    device-diagnostic
  • You will see a popup window appear.
  • Click Advanced and tick Apply repairs automatically
    Hardware-and-sevices-repair
  • Then hit Next and follow the steps until the troubleshooter is done

After the troubleshoot is done, simply restart your computer to apply the changes and see if your port is properly working now.

Force Windows to Install Pending Monitor Updates

Pending updates are any updates that aren’t automatically installed by the windows update software. As these updates are seen as non essential, users need to manually install them.

Here is how to install pending driver updates:

  • Press the windows key find Settings
  • Open the settings menu and click on Windows Update on the bottom left
  • Find the View Optional Updates tab and click it
    View optional updates
  • Tick the boxes that are related to your Display/ HDMI drivers and click Download and install
    optional driver updates

This is how any outstanding updates will appear, in my case there was an optional driver for my PC monitor. These updates can contain important data that the devices work as intended, and can interfere with their recognition by HDMI cables.

Run Windows in Safe – Mode

Running windows in safe mode will force all applications and settings to run at their default values. If some data regarding the HDMI controllers was corrupt, safe mode could potentially fix that issue.

To run your windows in safe mode do these steps:

  • Open the Windows Start menu
  • Type the command: msconfig and press Enter
  • Click on the Boot Tab
  • Find the Boot Tab with different settings
  • When the menu opens, clear the Safe Mode box that is ticked
    safe-boot
  • Follow the process until your windows restarts in safe mode

During Safe mode, try unplugging and then plugging the HDMI cable to see if your external device gets properly detected now.

Repair Your Registry Log

If there are some issues in the Registry files log, your hardware components might not appear correctly. To fix the registry, follow these steps:

  • Open the Windows Search bar and type: CMD
  • Run CMD as administrator
  • In the black popup screen, type: sfc /scannow
    command-prompt-sfc
  • Let your system scan all files
  • Restart your computer to apply these changes

Roll Back Your GPU Driver to a Previous Version

Sometimes returning to a previous driver version can remove some compatibility issues between your GPU and Monitor that are connected via an HDMI cable. 

Please let this be the last step that you attempt and make sure to keep a backup of your system files before you attempt to roll a driver to a past version back. 

To Roll Your GPU / Monitor Driver to a Prior Version Follow These Steps

  • Click on the Windows Start button
  • Type in: Device Manager and press Enter
  • Find your Monitor Driver under Monitors and right click it
  • Press properties
  • Click on “Driver” in the pop up menu
  • Click Roll Back Driver
    update-monitor-drivers
  • Repeat the same steps for your GPU
  • The GPU is located under “Display Adapters”

Restart your computer after rolling back to a prior driver version and try to plug and unplug your HDMI after restart to see if the issue persists.

HDMI Port Not Working on PS4 Fix

ps4-hdmi-port

A similar fix is available for your PS4 the same way as the TV. Ensure that no other HDMI cables are plugged into your main monitor/TV besides the HDMI cable from the PS4.

  • Locate the “Input” button on your remote controller 
  • Navigate to the “Output“/”Input” tab via the arrow buttons
  • Find the option that lets you change your Input port
  • Navigate to select “HDMI 1” and set it as the default output
  • If this does not work, try “HDMI 2“, etc.… until you get the correct picture to display

If these settings are done on your PC, you also have to check your PS4 inbuilt options to make sure that the HDMI cable is correctly selected as the Output/Input for your screen.

If none of these fixes work, try the following:

  • Use another HDMI cable to make sure the current one is not faulty
  • Physically inspect the HDMI connection on your PS4 and make sure it’s plugged in on both sides.
  • Restart your PS4 by holding the power button for 10 seconds. 

HDMI Port Not Working on a TV Fix

hdmi-tv-port

If you have done all previous troubleshooting steps and still get no output from the HDMI port, you have to troubleshoot the TV screen itself. 

The fix to force your TV to display a picture is very easy to do.

  • Locate the Input button on your remote controller 
  • Navigate to the Output/Input tab via the arrow buttons
  • Find the option that lets you change your Input port
  • Navigate to HDMI 1 and set it as the default output
  • If this does not work, try HDMI 2, etc.… until you get the correct picture to display

Check to see if your HDMI cable is appropriately set up.

Many TV’s have service providers that offer their Output terminal or router. Check if your HDMI cables are connected ONLY to the laptop/ computer / Console device. 

HDMI Port Has No Audio Output

An outdated or missing driver is a common fix to having no input or output from your Monitor’s in-built speakers/ microphone. If your HDMI port shows a picture but no sound, try these steps:

  • Open the Windows Search bar and type Device Manager
  • In the Device Manager menu, find the tab Sound, video and game controllers
  • Right click the driver and click Update Driver
    Sound,-video-and-game-controllers-driver-update
  • Restart your PC after it is done to apply the new updates.

Configure Your Display to Enable Sound

In my case, the HDMI port was working correctly, and the drivers were up to date, but the Display itself came with factory settings that disabled sound by default. To check if the sound is enabled on your screen, follow these general steps:

  • Locate the button that brings up your Display Menu
  • Go to the Sound Settings and check if it is enabled
  • Make sure that the screen is displaying through the correct port. Some VGA ports, for example, will only output a picture without any sound.

If you applied these steps and still have no audio output, do the following:

  • Try swapping out the connector cable to your Monitor
  • Try the Monitor with a different device to check if its faulty 

In case these steps don’t work you can run the sound troubleshooter instead.

  • Find the sound icon located on the right side of your task manager
  • Right click it and press Troubleshoot Sound Problems
    troubleshoot-sound-problems
  • Let the troubleshooter run its course

This is an inbuilt windows troubleshooter and it is useful for finding the exact source of the problem. Many times it will display an error message like: Sound output not found, or microphone is not plugged in, etc.

Finally…

The reason why your devices that are plugged into an HDMI are not correctly working is either because:

  • The HDMI port or cable are physically damaged or bent
  • The Drivers for your PC are not up to date, and they are preventing a picture/ sound from appearing
  • You have not configured your Display to be the main screen
  • The HDMI port you selected to be used is the incorrect one
