Setup, Compatibility & Care
Setup is straightforward, especially if using an LG C Series TV. The included mounting bracket allows for a clean, unified look by attaching the soundbar directly to the TV stand or wall. Connect the system to your TV via the HDMI eARC port to ensure high-bandwidth audio transmission. To care for your unit, keep the fabric surface free of dust using a soft, dry cloth. Ensure the subwoofer has at least a few inches of clearance from walls to prevent acoustic distortion, and perform a periodic check for firmware updates through the LG soundbar app to ensure ongoing compatibility with new media formats.
