HDMI is a popular high-quality connection method for both video and audio output, so it's no wonder that so many people are using it.

Speaking of HDMI, many Windows users reported that the HDMI port is not working on their Windows 10 PCs and laptops.

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

HDMI won't work on laptop
- In most cases, TV fails to recognize your laptop
HDMI audio won't play
- Oftentimes, video is available but 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 that you can do to fix this problem.

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

How can I solve HDMI output problems in Windows 10?

Check your hardware
Make sure that your HDMI device is the Default Device
Update your drivers
Rollback to the older driver
Install drivers in compatibility mode
Set your secondary display
Run a full system scan
Repair your registry
Update your OS
Clean your temporary files and folders
Remove recently installed software
Run System Restore
Replace your cable

1. Check your hardware

Make sure that the HDMI connection didn't slip out. Unplug and then plug the cable again. To make sure that the cable is well connected to your HDMI port, you can also invest in some new HDMI locks.

Turn on your HDMI TV or HDMI speaker and only then boot your PC. Then turn off the TV or speaker, unplug the devices altogether, wait for one minute, plug them back in and turn them on again.

Now that you refreshed your HDMI connection, follow the steps listed below.

Before diving into complex troubleshooting steps, first check your hardware. Make sure that the HDMI cable is inserted correctly and all the connections are fully functional.

2. Make sure that your HDMI device is the Default Device

Right-click on the volume icon on the taskbar.
Select Playback devices and in the newly open Playback tab, simply select Digital Output Device or HDMI.
Select Set Default, click OK.
- Now, the HDMI sound output is set as default.

First things first, if your HDMI device is not set as the default device, then the HDMI port will not be working on your monitor.

So make sure that the Show disconnected devices option is enabled so that your PC can display all the devices connected to it.

3. Update your drivers

3.1 Update drivers manually

Sometimes, all you need to do to fix these issues is to install the latest drivers. Just visit your graphics card or motherboard manufacturer's website and download the latest drivers from there.

You can also update your video and audio drivers using the Device Manager. Simply right-click the drive that you want to update and select Update Driver.

If you're using a laptop, it's better to download the drivers from the laptop manufacturer instead.

We also have to mention that in certain cases, old drivers can work better, so if the latest drivers aren't working for you, follow the steps from the previous solution to uninstall them and download the older version of the drivers.

If you want the latest GPU drivers, bookmark this page and always stay updated with the latest and greatest.

3.2 Update your drivers with an advanced tool

One common factor that can generate your HDMI port to not function properly is out-of-date drivers. Updating your device is crucial and we recommend you do this by using professional software.

Most of the time, the generic drivers for your PC's hardware and peripherals are not properly updated by the system. There are key differences between a generic driver and a manufacturer's driver.Searching for the right driver version for each of your hardware components can become tedious. That's why an automated assistant can help you find and update your system with the correct drivers every time, and we strongly recommend DriverFix. Here's how to do it:

Download and install DriverFix.
Launch the software.
Wait for the detection of all your faulty drivers.
DriverFix will now show you all the drivers that have issues, and you just need to select the ones you'd liked fixed.
Wait for the app to download and install the newest drivers.
Restart your PC for the changes to take effect.

DriverFix

4. Rollback to the older driver

Open Device Manager and find the buggy driver.
Right-click it and choose Uninstall.
Check Delete the driver software for this device and click OK.
Restart your computer.

Sometimes, it's better to use the default driver in order to avoid compatibility issues. In order to do this, you'll need to uninstall the current driver and the default one will install itself.

Open Device Manager and find the driver that is giving you trouble. Usually, it has an exclamation mark next to it.

Right-click it and select the Rollback driver option. This will install the previous version of the driver.

On Windows 10, you need to click on Properties and go to the Driver tab in order to find the Rollback option. However, it is usually greyed out, as you can see in the screenshot below.

5. Install drivers in compatibility mode

Right click the driver setup file and choose Properties.
Then go to Compatibility tab.
Check Run this program in compatibility mode and choose Windows 7 from the list.
Click Apply and OK.
Run the setup file.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

6. Set your secondary display

Open Nvidia Control Panel.
Go to Set up multiple displays.
If your HDMI connected display isn't showing ,try checking and unchecking the other ones on the list.

If you're using HDMI to connect a second display to your PC, try setting it over in NVIDIA's Control Panel. If you use an AMD graphics card, use its Control Panel instead. The process is the same for both cards.

This sounds like an obscure solution, but some users reported that it helped them to enable the HDMI display.

7. Run a full system scan

Go to Start then type defender, double click Windows Defender to launch the tool.
In the left-hand pane, select the shield icon.

On the Disk Cleanup tab, select the check boxes for the file types that you want to delete, then click OK and selectDelete files.

The simplest and quickest manner to delete your temporary files and folders is to use Disk Cleanup. As you use your computer or browse the Internet, your PC accumulates various unnecessary files.
