Performance Highlights

• Vibrant HDR Playback: Dynamic tone mapping via HDR10 Pro fine-tunes brightness levels scene-by-scene. This optimization ensures deep shadow detail and vivid contrast even on an entry-level Direct LED panel. 
• Smart webOS Ecosystem: The TV runs the latest webOS platform featuring LG Gallery+, which transforms your dark television screen into an active artwork and landscape frame when not in use. The integrated Home Hub provides a centralized control board for managing compatible smart home appliances. 
• Audio Enhancements: Audio rendering utilizes AI Sound Pro to continuously evaluate room acoustics and the playing genre, creating tailored virtual spatial sound. WOW Orchestra synchronization blends the internal TV speakers seamlessly with compatible LG soundbars for a wider front audio stage.
