Dealing with no sound issue on your LG monitor can be frustrating, especially when relying on it for work, entertainment, or gaming. Whether you’re in the middle of a video call, watching your favorite show, or in the heat of a game, sound is an essential part of the experience. The good news is that most sound issues with LG monitors are easy to resolve with a few simple DIY troubleshooting steps. From checking the basics, like volume settings, to more advanced fixes, we’ve got you covered every step of the way.
Reasons for the LG Monitor “No Sound” Problem
If you can’t hear sound from your LG monitor, there are a few potential causes. Below are some of the major reasons for the sound issue on your device.
- The sound could be muted or set too low on your LG Monitor.
- Some LG Monitors don’t include built-in speakers, so you must connect an external speaker to the PC.
- Your PC might not send sound to the LG Monitor due to incorrect audio output settings.
- Faulty or loose cables (HDMI, DisplayPort, or USB-C) could be the reason for this issue.
- An outdated or missing audio driver on the LG Monitor could prevent sound from being routed correctly.
DIY Solutions to Fix “No Audio” Issue on LG Monitor
After knowing the cause of this issue, you can fix it by following the steps given below. These DIY solutions will help restore sound to the LG monitor in no time.
Check the Monitor’s Volume Settings
Before diving into more complex solutions, ensure the volume on your LG monitor is set properly. Most LG monitors have a joystick or control button located at the bottom. Press the joystick to open the on-screen menu, then use the right control to increase the volume. Double-check that the monitor is not muted or set too low. If the volume is fine, but you’re still not hearing any sound, move on to the next step.
Check Your Cable Connections
A common culprit behind sound issues is loose or damaged cables. Whether you are using HDMI or other Audio cables, an improper connection can cut off the sound from your monitor.

- Inspect HDMI/AUDIO Cables: Ensure the HDMI cable or other audio cable you use is securely plugged into the LG monitor and the source device.
- Check for Damage: Look for any damage on the cables. If you find any fraying or broken connectors, it’s time to replace them.
- Reconnect the Cables: After checking and replacing cables (if necessary), restart the devices and check if the sound returns.
Still no sound? proceed to the next troubleshooting step.
Restart Your Devices
Minor software glitches or temporary issues can sometimes interfere with the audio. Restarting your devices often clears up these bugs.
- Power Cycle the Monitor: Turn off your LG monitor, unplug the power cord, and wait a few minutes. Then, turn it On.
- Restart Your Computer or Device: Similarly, restart the device connected to the LG Monitor.
- Test Sound: After reconnecting and powering everything back on, play any audio to check if the sound works.
If the sound is still not working, it’s time to dive into the monitor’s settings.
Check the Monitor’s Audio Settings
Your monitor’s settings could be misconfigured, preventing sound from coming through. Let’s make sure everything is set correctly.

- Go to the Menu: Open the monitor’s on-screen display (OSD) menu using the joystick or control button.
- Select Audio Settings: Look for options labeled “Sound” or “Audio Settings.”
- Audio Output: Make sure that the monitor’s internal speakers are set as the output device.
- Adjust Volume: Confirm the volume is turned up, and the monitor is not muted.
After adjusting these settings, test the sound again.
Inspect the Computer’s Sound Settings
The audio issue on your LG monitor could also be due to the incorrect computer’s sound settings.
For Windows:
- Set Monitor as Default Device:
- Open the Start Menu → Control Panel → Hardware and Sound → Sound.
- Right-click your LG Monitor in the playback devices list and select Set as Default Device.
- Enable Loudness Equalization:
- In the Sound menu, click your monitor, then select Properties.
- Under the Enhancements tab, check the box for Loudness Equalization to boost sound levels.
- Adjust Volume:
- Go to Control Panel → Hardware and Sound → Sound, then Adjust System Volume. Ensure that both the system volume and monitor volume are at an appropriate level.
For Mac:
- Open System Preferences → Sound → Output.
- Select your LG Monitor as the output device.
- Ensure the volume slider is adjusted properly and that the sound is not muted.
Update Audio Drivers
Outdated or corrupted audio drivers could be blocking the sound. Updating them can often resolve the issue.
- Open Device Manager: Press Windows + X and select Device Manager.
- Expand Audio, Video, and Game Controllers.
- Update Audio Drivers: Right-click the audio device (e.g., Realtek(R) Audio) and select Update Driver.
- Automatic Update: Hit Search Automatically for Updated Driver Software and follow the instructions.
If this doesn’t work, uninstall the driver and restart your PC to reinstall it automatically.
Once the drivers are updated, restart your PC and check if the sound works.
Perform a Factory Reset on the LG Monitor
If none of the steps have worked, performing a factory reset on your LG Monitor can help eliminate any software glitches or configuration issues that might be affecting the sound.

- Reset Process: On the monitor’s OSD menu, look for the Reset option. Select it, and then confirm to reset the LG Monitor to its default settings.
- Reconfigure Settings: After the reset, you need to set up the sound and display preferences again.
This step can solve issues caused by custom settings that may have interfered with the sound output.
Reach Out to LG Customer Support
After all these steps, if your LG monitor still isn’t producing sound, it is time to reach out for professional help. Contact LG’s customer support team through their official website for further assistance or if you face any hardware issue that needs repair.
If your LG monitor doesn’t have built-in speakers, connect external speakers or headphones to get audio. Many LG monitors offer a 3.5mm audio-out jack, which lets you connect speakers or headphones directly to the monitor. Use a 3.5mm audio cable to plug your speakers or headphones into the monitor’s audio-out port. If your monitor supports Bluetooth or your computer has Bluetooth connectivity, pair it with Bluetooth speakers or headphones for wireless audio.
