Black hdmi in laptop

HDMI is a very good technology because it sends both a video signal and an audio signal over one cable. There are a few settings that can need to be adjusted to get an HP laptop to send an HDMI signal, and in other cases it can not work even when everything is set correctly. In this article, I will explain how to troubleshoot an HDMI cable that isn’t working with an HP laptop.

As a general rule, start by disconnecting and reconnecting the HDMI cable. After that try restarting your computer, check the correct port is set on the display device, set the sound output to HDMI in the Windows settings, run the Windows troubleshooter, and update the drivers.

Each of these steps should be done one by one, until the issue is solved. In some cases the HDMI cable itself can be faulty, so try a different HDMI cable if you have one. Below, I will cover each of these steps in detail with easy to follow instructions.

HP Laptop HDMI Not Working (How to Troubleshoot)

The HDMI signal from an HP laptop to a display device can work straight away without adjusting any settings. But, in other cases it won’t work. This is what to do when your HP laptop doesn’t display the audio or video signal from an HDMI cable.

Overall, begin by trying a different HDMI cable if you have one. Next, unplug and then plug in the HDMI cable on both ends. Then, restart your computer, make sure the display device is on the right channel, for example HDMI1, or HDMI2. After doing that do the steps below.

Note: each of these solutions below has the potential to solve the issue and get it working again. Therefore after performing each step see if it has fixed the problem. And if not move on to the next step.

1. HDMI cable is faulty or not plugged in

The HDMI cable can be slightly loose on either end. Start by unplugging it, and plugging it back in on both ends. The HDMI cable itself can be faulty, or it is not plugged in all the way.

If you have a spare HDMI cable, or an HDMI cable that is plugged in to another device, swap it out for your existing HDMI cable.

2. Restart the display device and your HP laptop

Electronic devices like your laptop and the display device have an internal computer. From time to time the code that runs it can freeze. This can cause various glitches which can cause a port such as the HDMI port not to work.

And various other issues. Restarting it will close everything it’s running and start it again. Which can solve this issue.

Therefore, it’s a good idea to restart both your HP laptop and the display device. Most display devices can be restarted by turning them off, or onto the stand by mode. Then unplugging them at the wall, waiting for about 10 seconds, and then plugging them back in again.

With your HP laptop restart it by holding down the power button until it shuts off, and then press the power button again. Or, by selecting restart in the start menu by clicking the arrow next to ‘Shut Down’ and selecting restart.

3. Laptop is not set to output HDMI output

An HP laptop by default will send the video signal to the built in monitor rather than an external monitor. To send the video signal to the external monitor you need to change the settings in Windows.

Here’s the steps for how to do that:

  1. Press both the letter ‘p’ on the keyboard and the Windows key on your keyboard at the same time.
  2. The display settings will open and give you 4 options.
  3. Choose either ‘Duplicate’, or ‘Second screen only’.

Duplicate will show the video output on your laptop screen and the display device your HDMI cable is plugged into. Whereas, ‘second screen only’, wont show anything on your laptop screen, only on the display device your HDMI cable is plugged into. Choose whichever one you prefer.

4. The display device is on the wrong channel

Display devices typically have more than one HDMI port. For example, they can have HDMI1, HDMI2, and HDMI3. If the HDMI cable is plugged into HDMI1, but the display device is set on HDMI2 it will say no signal. Have a look at what HDMI port the HDMI cable is plugged into at the back of the device.

Such as, whether it’s plugged into HDMI1, or HDMI2. Then make sure the display device is set to the HDMI port that the HDMI cable is plugged into. For example, if the HDMI cable is plugged into HDMI1, make sure the display device is displaying HDMI1.

This is changed using the remote for the display device. Or, by accessing the menu using the buttons on the display device.

5. Set sound output to HDMI in settings on Windows

For issues where there is no sound but the video is displaying, you should go into the audio settings in Windows and make sure the output is set to HDMI. To do that open the start menu on Windows, and type in ‘audio settings’. An option will come up that says ‘Change sound card settings’.

Click on that and a window will open. It will list each of the audio devices, such as the headphone port, onboard speakers, and the HDMI device.

Make sure the HDMI device is selected. Then click apply and close the window.

6. Run Windows Troubleshooter

This step is specifically for audio issues. So, if the issue is with the video signal only skip this step. Windows has an inbuilt troubleshooter that will identify and solve any issues such as the audio output. To run it open the start menu and then type in ‘troubleshooter’.

It will show an option at the top of the start menu that says ‘find and fix problem’. Click on that and it will open the troubleshooter. In the right hand side scroll down and you will see an option to troubleshoot the audio devices.

Click that and it will diagnose and detect any issues with the audio. It doesn’t always find an error, but can fix this issue.

7. Update display and sound drivers

Devices such as the graphics card, and sound card on your computer have software called a driver. This is required for it to communicate with Windows to work correctly. These can be set to automatically update, or can need to be updated automatically.

The ones you should update are ‘display adapter’, ‘audio devices’, and ‘HDMI port’. It will check if there is a newer version of the driver. If there is one available it will give you the option to update by downloading it from the internet.
