ONN Monitor No Sound [You Should Try This First!]

1- No Built-in Speakers

ONN monitors are typically designed without in-built speakers or audio jacks. 

This means that to hear the sound, these monitors must be connected to external devices such as PCs, gaming consoles, and soundbars with their separate audio outputs.

The lack of speakers doesn’t mean the monitor is incapable of outputting audio; in many cases, the monitor’s visuals can be paired with audio from a connected device.

However, some users may find it inconvenient to have to connect their other devices for sound output when using an ONN monitor. 

If this is the case, people may want to consider purchasing a monitor that is designed with built-in speakers or audio jacks.

It’s important to note that the decision between purchasing a monitor with sound or without should depend on individual needs and preferences.

2- Desired Audio Source

If the ONN monitor has no sound, it may imply improper setup of the input source or plugging in of speakers. 

This could mean that the output port on your computer is not configured to broadcast its sound or that you have not plugged the speakers into the proper port. 

It may also be because your computer’s audio settings are not set to send out sound from a particular port. 

To fix this issue, first, ensure all connections and settings are properly configured for an ONN monitor to work with sound; if it still does not work, then check for issues with faulty cables.

3- Bad Audio Cable

One reason why your ONN monitor is operating silently could be due to a bad audio cable. 

If you are connecting your monitor to a device such as a laptop or gaming console using an audio cable. 

There may not be sound if the audio cable is damaged physically and this affects the quality of connection substantially, resulting in no sound at all.

Another explanation for why your ONN monitor has no sound might be due to missing or incorrect driver software. 

Driver software determines how hardware interacts with other components, so it is very important when installing new hardware on your computer.

4- Defective Audio Card

If your ONN monitor is not producing sound, then the audio card might have become defective. 

An audio card is an expansion card that allows a computer to produce sound. 

It processes the audio signal from the computer and sends it out through the monitor’s speakers. 

If your audio card has malfunctioned, you will be unable if hear any sounds coming from your ONN monitor. 

If you want to diagnose whether this is an issue, you can try plugging in a set of headphones or external speakers into your computer and check if they produce sound. 

If there are no sounds coming from the headphones or external speakers when plugged in, it means that it is likely something wrong with your computer’s sound card. 

In this case, you will need to replace the audio card so as to restore the sound on your ONN monitor.

5- Low Volume or Mute

If you are having trouble with the sound on your ONN monitor, it could be because the volume is turned too low or it is completely muted. 

To check, look for the corresponding volume control buttons on the side of your monitor. If the volume is set too low, adjust it up to an audible level. 

If the monitor is completely muted, unmute it and make sure the volume is set to a suitable level. 

If your ONN monitor still does not produce sound even though you have adjusted the volume and checked that it is not muted, then unfortunately, this means that your monitor does not come with built-in speakers.

6- Loudness Equalization Settings

The sound output of the ONN monitor can be affected by various settings, and one of them is Loudness Equalization Settings. 

These settings help users in adjusting the volume level of certain frequencies to make subtle adjustments to their sound quality. 

For instance, if a person has difficulty hearing higher or lower frequencies, boosting or reducing the volume levels of those frequencies using Loudness Equalization Settings can be beneficial. 

However, it’s important to keep in mind that ONN monitors do not have any sound output capabilities; therefore, any adjustments made will not be heard. 

If someone wants to hear such adjustments they may need external speakers or headphones for their devices instead. 

Ultimately, ONN monitors don’t have any sound output capacity but still benefit from equalization adjustments for better-quality sounds.

7- BIOS Audio Settings

One of the possible reasons why your ONN monitor might have no sound is due to incorrect BIOS audio settings. 

The BIOS, or Basic Input/Output System, is a software program stored on a chip in your computer’s motherboard that helps configure the hardware and other settings. 

If the BIOS audio settings are incorrect or disabled, then this could be why you’re experiencing no sound coming from your ONN monitor.

To fix this issue, it’s important to boot into the BIOS setup utility and verify that the audio settings are properly enabled. 

You can do this by pressing a certain key during startup (usually F2, DEL, ESC) to open up a boot menu. 

Once you’re in the BIOS setup, look for any audio-related settings such as “Enable Audio” or similar.

If the settings are already enabled, then you may need to contact your computer’s manufacturer to determine if there is a BIOS update available that could help resolve the issue.

8- Update Audio Drivers

When it comes to updating audio drivers on an ONN monitor, the process can be a simple one. 

Keeping the audio drivers up-to-date is essential for optimal performance in any audio-related activity, such as listening to music or streaming videos. 

When your ONN monitor is having problems with the sound or no sound at all, updating the audio drivers might help to resolve the issue. 

It is best that you back up all of your existing data and settings before beginning this process just in case something goes wrong during the update.

To begin the update process:

  1. Open your computer’s Device Manager and locate the ONN monitor’s audio driver.  
  2. When you have located it, right-click on the item and select “Update Driver Software.”  
  3. This will allow you to search online for available updates or download them manually.  
  4. Choose the method that works best for you, and follow the instructions to complete the update.

Once the audio driver has been successfully updated, restart your computer to ensure all changes have taken effect.


In conclusion, if your ONN monitor has no sound, you can fix this problem by following these steps:

  1. No Built-in Speakers
  2. Desired Audio Source
  3. Bad Audio Cable
  4. Defective Audio Card
  5. Low Volume or Mute
  6. Loudness Equalization Settings
  7. BIOS Audio Settings
