LG monitors with built-in speakers
LG produces a range of monitors, some with built-in speakers and some without. The Ultragear series, for example, does not have built-in speakers. However, LG monitors with built-in speakers are available for purchase on Amazon and Best Buy.
For those LG monitors without speakers, it is possible to connect an external speaker. This can be done by connecting an external speaker or headset to the 3.5mm AUX port, or Headphone Out port, at the back of the monitor. It is also possible to transmit audio via an HDMI cable.
If you are experiencing sound-related issues with your LG monitor, there are several troubleshooting steps you can take. Firstly, ensure that the output device is set to your LG monitor by clicking the Speaker icon on the right side of the taskbar and selecting your desired output device. You can also open the volume mixer and reset the sound devices and volumes for all apps to their recommended defaults. If you are using Windows 10, you can increase the volume of individual apps using the slider in the volume mixer.
In some cases, sound issues may be related to the PC sound driver. You can uninstall and reinstall the sound driver by following the instructions provided by your PC manufacturer. Additionally, you can use the LG Update program to install device drivers that are suitable for your PC system.

Troubleshooting sound-related issues
Not all LG monitors have built-in speakers. If your LG monitor has no sound, it could be due to incorrect configuration settings, loose cables, or a faulty cable. Here are some troubleshooting steps you can try:
Check cable connections
Ensure that the cable connecting the monitor and the PC (HDMI, DP, USB-C) is correctly plugged in. Check for any signs of damage, such as bent pins, and also look for any dust or dirt that may be sticking to the pins. If you suspect the cable is faulty, try connecting a different cable and test for sound.
Adjust volume levels
Ensure that the volume is up on both the monitor and the connected device. On your PC, verify whether the Windows sound output is set to the monitor. Check whether the sound is muted, and if so, unmute it. You can adjust the volume by clicking on the sound icon on the right side of the taskbar and using the slider.
Reconfigure sound settings
Click on the speaker icon on the right side of the taskbar and select a sound output. Check whether the output device is set to the LG monitor. Right-click on the speaker icon and select "Open volume mixer". If any apps have been muted, click "Reset" to reset the sound devices and volumes for all apps to the recommended defaults.
Update or reinstall sound drivers
If the issue persists, it may be a PC sound driver issue. Update your sound drivers to the latest version by downloading them from the manufacturer's homepage. For LG PCs, you can use the LG Update program to automatically install suitable device drivers. Alternatively, you can uninstall the current sound driver and reinstall it by following the instructions provided by your PC manufacturer.

Connecting an external speaker
Some LG monitors do have built-in speakers, but this feature is not available on all models. If your monitor does not have built-in speakers, you can connect an external speaker.
The process of connecting an external speaker to your LG monitor will depend on the model of your monitor and the type of external speaker you want to use. Here are some general steps and guidelines to follow:
- Check your monitor model: Different LG monitor models have different port configurations. Identify the ports available on your monitor by checking the back of the monitor or referring to the product user manual. Common ports found on LG monitors include HDMI, DVI, DP, USB-C, VGA, and AUX.
- Choose a compatible connection method: The most common ways to connect external speakers to a monitor are through an AUX (3.5 mm headphone jack) connection or an HDMI connection. If your monitor has an AUX port, you can connect speakers or headphones directly into this port. If your monitor has an HDMI port, you can use an HDMI cable to connect to external speakers or a soundbar.
- Connect the speaker: Once you've identified the correct port and connection method, simply plug your external speaker into the corresponding port on the back of your monitor.
- Adjust audio settings: After connecting your external speaker, you may need to adjust your audio settings to ensure the sound is outputting through the correct device. On Windows, click on the speaker icon in the taskbar, select a sound output, and choose the LG monitor as the output device if it is not already selected. You can also open the volume mixer and adjust the volume for specific apps.
- Troubleshoot if necessary: If you are experiencing audio issues, ensure that the cable connections between your monitor and PC are secure and undamaged. You may also need to update or reinstall your sound driver. LG provides an LG Update program that can help install suitable device drivers for your PC system.
Remember to consider the compatibility of your external speaker with your monitor and follow any specific instructions provided by the manufacturers.

Adjusting volume levels
The process of adjusting volume levels on an LG monitor depends on the model. Some LG monitors have built-in speakers, while others do not. If your monitor has a built-in speaker, you can adjust the volume using the joystick button below the monitor by moving it left or right.
For smart TV monitors, you can use the dedicated remote control to adjust the sound by pressing the sound setting button. You can also use the joystick button on the monitor to set the sound. To use the TV speaker, go to the Settings Menu, select Voice, then choose Output Speaker Selection, and finally select TV Speaker.

On a Windows PC, you can adjust the volume by pressing the hotkeys [Fn] + [F11] ~ [F12]. You can also adjust the volume by clicking on the speaker icon on the taskbar, selecting "Open Volume Mixer," and using the slider to increase or decrease the volume for specific applications.

Sound drivers
Some LG monitors have sound, but this depends on the model. If your LG monitor has no sound, you can try troubleshooting by checking the cable connections and settings. If this does not work, you may need to update your sound driver.
Audio drivers are time-sensitive, so if they don't process audio quickly enough, you may experience silence or audio dropouts, which can manifest as crackles or pops. To prevent this, audio drivers use a buffer, which is essentially a queue of audio samples waiting to be processed.
If you are experiencing sound issues, you should first check that your audio driver is up to date and update it if necessary. If this doesn't solve the problem, you can try uninstalling the audio driver, which will then reinstall automatically. If this still doesn't work, you can try using a generic audio driver or rolling back your audio driver. You can also try to find a new driver on the device manufacturer's website and follow their instructions to install it.
