If there’s no sound coming from your monitor, first check the product specifications to see if it has built-in speakers.
If your monitor has built-in speakers but you still hear no sound, check the signal cable connections (HDMI, DP, USB-C) and your Windows sound output settings.
If the issue persists, contact LG Customer Support for further assistance.
Why Is There No Sound from the Monitor?
- The monitor may not have built-in speakers, or the volume may be muted.
- The HDMI, DP, or USB-C signal cable connecting the PC and monitor may be damaged or not securely connected.
- The Windows sound output device may be set to a device other than the monitor.
- Audio may not work due to cable version or compatibility issues between the monitor and the connected device (such as a PC).
How to Fix No Sound from the Monitor
Check If Your Monitor Has Built-in Speakers
If there is no sound from your LG monitor, first check the product specifications to see if it has built-in speakers.
- 1.Go to the LG website, click the Search (magnifying glass) icon at the top right, enter your model name, and press Enter.
- 2.Select the product image and check the Specifications to see if speakers are listed.
* Note: If your monitor does not have built-in speakers, sound will not play through the monitor. Connect external speakers.
Check the Monitor Volume
- Move the joystick button on the bottom of the monitor left or right to adjust the volume and make sure it is not muted.
- If sound plays when external speakers or earphones are connected to the back of the monitor, your monitor likely does not have built-in speakers.
Check the Signal Cable Connections (HDMI, DP, USB-C)
- Make sure the signal cable connecting the PC and monitor is securely connected. If the cable appears damaged, try a different cable to see if sound plays.
- We recommend using an HDMI 2.0 or DP cable that supports 4K at 60 Hz. Audio may not work due to cable version or compatibility issues.
* Note: Sound may not play if you use an adapter or converter to connect different types of ports.
Change the Windows Sound Output Device
- 1.Click the [Speaker] icon on the bottom right of the Windows taskbar, and check if [LG Monitor] is selected as the sound output device.
- 2.If another device is selected, change it to your LG monitor.
Reinstall the Sound Driver
- 1. If the monitor does not appear in the list of sound output devices, open [Device Manager] from the Windows search bar, uninstall the existing sound driver (such as Realtek(R) Audio), and restart your PC.
- 2. After restarting, install the correct sound driver for your PC.
* Note: Driver installation steps may vary depending on your PC or audio device manufacturer. Please refer to the manufacturer’s support guide for detailed instructions.
