It can be frustrating to connect your LG monitor to your computer or other device and find no sound from the built-in speakers.
There are a few common reasons why your LG monitor may not be outputting sound and some simple steps you can take to resolve the issue.
Check Your Connections
The first thing to check is that your audio connections are hooked up correctly.
Most LG monitors have an audio input port resembling a standard 3.5mm headphone jack.
Ensure you have an audio cable plugged from your PC or device into this audio input port on the monitor.
The cable should be fully inserted on both ends.
If you are trying to get sound through an HDMI connection, check that you don’t have an older HDMI cable.
Older HDMI cables may only support video and not audio.
Try swapping it out for a newer HDMI cable that mentions audio support.
Change Your Default Playback Device
If your audio connections are set up correctly, the next thing to check is that your LG monitor is the default playback device in your operating system’s audio settings.
In Windows, go to Control Panel > Hardware and Sound > Sound.
Under the Playback tab, ensure your LG monitor is selected as the Default Device.
Go to System Preferences > Sound in macOS and select your LG monitor in the Output tab.
Setting your LG monitor as the default playback device routes audio to it by default.
Update Your Audio Drivers
Outdated audio drivers can also prevent sound from properly coming through your monitor’s speakers.
Install the latest audio drivers from your graphics card manufacturer’s website.
Updating to the newest available audio drivers can resolve compatibility issues.
Adjust Your Monitor Settings
Your LG monitor may also have an option in its onboard menu system to enable/disable speakers or audio output.
Use the monitor’s menu buttons to access the onboard menu and look for audio settings.
Make sure the internal speakers are not disabled or turned off.
Some LG monitors have a volume control option within their menus as well.
Access your monitor menu and ensure the volume is turned up and not muted.
This ensures the monitor speakers are not just set too low.
Reset Your Monitor
If you still can’t get audio after trying the above steps, resetting your LG monitor’s settings to factory defaults may help resolve software-related audio issues.
Refer to your monitor’s menu or manual for the factory reset option.
Resetting will revert the monitor’s settings to default, like volume and sound output options.
Contact LG Support
If you still cannot get your LG monitor to output sound after trying these troubleshooting tips, it’s time to contact LG support.
Provide the detailed model number and explain the issue you are having.
LG may suggest further monitor-specific troubleshooting steps to resolve your no-sound problem.
