How to Check if Your LG Monitor Has Built-In Speakers

• Check your user manual to see if your monitor has built-in speakers.
• You can also move the joystick button on your monitor frame left or right. If the volume control appears on the screen, your monitor has built-in speakers.

2. 2. Select the Settings icon on your screen.
3. 3. Select Support.
4. 4. Select Sound Self-Diagnosis.
5. 5. Check if you can hear the test sound.
   If you hear the test sound, check the audio settings on your connected PC or external device.

1. 1. Select the Speakers icon on the right side of your Windows 11 taskbar.
2. 2. Open Select a Sound Output.
3. 3. Check the available output devices.
4. 4. Select your LG monitor or the display audio device connected through HDMI, DisplayPort, or USB-C.
5. 5. Make sure the output is not muted, and then adjust the volume.

If your LG monitor does not appear in the Windows 11 sound output list, check if your PC recognizes the monitor's audio connection.

Reconnect Your Monitor and PC

2. 2. Disconnect the HDMI, DisplayPort, or USB-C cable.

1. 1. Press the joystick button on your monitor.
2. 2. Open Input.
3. 3. Select Input List.
4. 4. Select the HDMI, DisplayPort, or USB-C input connected to your PC.

Check if Windows Recognizes the Audio Device

1. 1. In Device Manager in Windows 11.
2. 2. Expand Sound, Video and Game Controllers and Audio Inputs and Outputs.

   Check if your monitor or a display audio device appears. (The audio device may not appear as 'LG Monitor.'
   Depending on your PC and graphics hardware, it may appear under a name that includes HDMI Audio, Display Audio, or the graphics device manufacturer.)

3. 3. If the required display audio device is missing or shows an error, check your PC audio and graphics drivers.

Update or Reinstall Your PC Audio and Graphics Drivers

Even if your monitor displays correctly, sound may not play if there is an issue with your PC's display audio device.
Check the support page of your PC or graphics hardware manufacturer for the latest audio and graphics drivers, and install them following their instructions.
If you are using an LG PC, you can use the LG Update Installer to install the correct drivers.
After installing or updating the drivers, restart Windows and check if your monitor appears as a sound output device.

If your LG monitor appears correctly as the output device but you cannot hear sound from a specific app, check the volume settings for that app.

1. 1. Right-click the Speakers icon on your taskbar.
2. 2. Select Open Volume Mixer.
3. 3. Check if the app is muted.
4. 4. Increase the volume for the app if necessary.
5. 5. If the issue persists, select Reset to restore the audio devices and app volumes to their recommended defaults.

Even if your screen displays correctly, the audio device might not be recognized. If you experience sound issues, check your cable connections by following these steps:

1. 1. Make sure the cable is securely connected to both your PC and monitor.
2. 2. Check the connectors and pins for any bends or damage.
3. 3. Check the ports for dust or debris.
4. 4. If another compatible port is available, try connecting the cable to it.
5. 5. If possible, test the connection with another compatible cable to see if the sound plays.
