HDMI Laptop to TV Not Working/No Sound/No Picture

As a laptop owner, I recently ran into a frustrating issue with my HDMI setup. No matter how I tried to get my laptop connected to my TV, I couldn’t seem to get the picture and sound to work. After doing some research, I found some tips and tricks that helped me successfully connect my laptop to my TV.

In this blog post, I’m going to share all the solutions I found and how I eventually solved the problem. So, if you’re having trouble connecting your laptop to your TV, this post is for you!

When you connect an HDMI laptop to a TV, and it doesn’t work -no sound or picture- try checking the settings. It could also be due to the HDMI cable itself. These are the usual culprits which you can quickly resolve. 

Why Is My HDMI Laptop to TV Not Working?

You’re missing something if you often find yourself in some technical glitch concerning your HDMI linked to a TV. It can be stressful to some who aren’t tech-savvy as it takes a toll on their time and patience. 

If you’re wondering what could’ve been wrong, it could be the HDMI cable, incompatible OS, TV settings, or the display settings in your computer. 

Whatever it may be, you should be patient and thorough when sorting it out. 

You can restart your computer before changing your laptop or TV settings as your first step in resolving the issue. It’s a simple troubleshooting trick that works most of the time.

Why Is My HDMI Laptop to TV Not Producing Sound?

You’d need to do some trial and error before being able to diagnose the audio problem with an HDMI connection. Follow these steps to fix the sound in your TV after connecting it to your laptop with an HDMI.

  1. HDMI Cable

Sometimes, an incompatible or defective HDMI cable is the problem. You need to see first if it’s indeed the cause of your audio concerns. Here’s how you can do it: 

  • Check the HDMI cable if it’s loose.
  • Try to connect it to another TV or monitor with speakers.
  • Test for sound output after connecting the cable. 
  • The HDMI cable isn’t the issue if the audio is good.
  1. Computer Settings

The next step is to check the default sound settings on your laptop. 

You won’t hear any sound if you have speakers instead of HDMI in your default settings. Another reason would be the wrong audio driver installed or the set default audio playback device.

TV as Playback Device

Here are the steps to update the sound settings on your computer.

  • Go to your laptop’s settings and set your TV as the output device.
  • Test for sound by playing a video or music.
  • The issue is probably the audio driver if there’s still no audio after setting your TV as the default sound device.

Audio Driver

An incompatible or outdated audio driver can also cause audio problems. You can fix this by updating the audio driver to the latest version. If it’s still giving you the same results, try uninstalling and then reinstalling the audio driver on your laptop.

Opt for Windows Troubleshooter

If the steps above aren’t working, try running the Windows troubleshooter tool on your laptop. 

  • Go to your computer’s system settings and click “Sound.”
  • Choose the advanced sound settings and select “Output Devices.”
  • A prompt will appear on your screen, informing you that Windows will perform some diagnostics to identify the problem.
  • Do the recommended steps on your computer.
  • Restart your laptop after troubleshooting to run any system updates.
  1. Outdated Operating System

An outdated Windows can create bugs in your computer, such as audio problems. To verify updates on your laptop, do these:

  • Go to your computer’s system settings and click “Update & Security.”
  • Choose “Windows Update” and check the status of your computer.
  • Install available updates if your laptop suggests it.
  • Restart your laptop and observe if it fixes the bug.
  1. Other Factors Affecting the Sound Output

Sometimes, the root cause of audio problems isn’t as complicated as we might think. Check the 

sound settings for any of the following:

  • A mute audio or disabled sound.
  • A headphone attached to the laptop is where the sound is coming out.
  • Volume is too low.

Why Is My HDMI Laptop to TV Not Showing Picture On the Screen?

After connecting your TV to your laptop via HDMI, you need to troubleshoot when your TV doesn’t display anything on the screen.

Common reasons for no video output include a faulty HDMI cable, a wrong input method, display settings, and software problems.

Let’s find out the probable reason why your TV isn’t receiving an image from your laptop connected via HDMI:

  1. HDMI Cable Connection

Before going through the complicated steps of diagnosing and resolving the video bug, do a simple HDMI check.

Look into the HDMI cable first. A loose connection and a faulty HDMI cable are the usual reasons for no picture on your TV.

Inspect the cable and look for signs of damage. If you see one, it’s time to buy and change your HDMI cable. However, if your HDMI is relatively new, try unplugging it first. Reconnect it after a few minutes and observe if it gives you a positive result.

  1. Input Method of the TV

A typical error for some who are using their TV for video output is choosing the wrong input method of the TV. 

When you connect your TV to your laptop via HDMI, choose the correct input device in the remote. It should correspond with the connected device. For example, if you inserted it into HDMI 1, you should select the same input on the TV using the remote.

  1. Laptop Display Settings

It’s essential to change the display settings on your laptop when using a TV as an extension of your monitor. Here’s how you can do this:

  • Open the system settings of your computer and click on “Display.”
  • Go to “Scale and Layout” and select “Multiple Displays.”
  • Click “Detect,” then look for your TV from the dropdown list.
  • Once you see your TV, click “Apply.” 
  • You should see a picture on the TV after.
  1. Outdated Graphics Driver

If all the other resolutions haven’t worked, perhaps the problem is your outdated graphics driver. You need to update it to the latest version for the HDMI to start working.

Restart the TV

Once you’ve done all the necessary solutions, a simple TV restart may troubleshoot the setup and may start working in your favor. Sometimes, it needs a quick reboot to fix the video bug.

Conclusion

Connecting an HDMI laptop to a TV can sometimes produce no sound or picture. If this happens, do a trial and error to resolve the system glitch. Most of the time, the reason for the bugs is pretty apparent. It could be due to faulty HDMI or the computer settings.
