If your LG monitor speakers are not working, it can be caused by the configuration settings being incorrect, or due to a loose cable. This is normally resolved by checking the cable connections, adjusting volume levels, or reconfiguring the sound settings.
Not all LG monitors include built-in speakers. It is recommended to check the specifications of your specific LG Monitor for effective troubleshooting.
Make sure all cable(s) are fully connected between the PC and Monitor.
