Adaptive Sound

Adaptive Sound has audio scenic intelligence that optimizes sound based on real-time scene analysis by content type.



Sustainability

Save energy with intelligent analysis

AI Energy Mode

Easily reduce your power consumption by turning on AI Energy Mode. Your TV will auto-adjust its brightness based on the room's lighting and your user activity. It also subtly adjusts brightness during different scenes to save even more energy.

When AI Energy Mode is off, the surroundings around the TV appear bright. A smartphone screen displaying AI Energy Mode pops up, and it switches from Off to On. With adaptive brightness and AI Energy Mode activated, the energy level decreases significantly, and the scale shifts from day to night.

With adaptive brightness and AI Energy Mode activated, the energy level decreases significantly, and the scale shifts from day to night.

* Energy saving rate may vary by region, model, size, viewing conditions and type of content.  * Products shipped in Eco Mode have some AI Energy Mode functions enabled by default, so energy saving levels when AI Energy Mode is turned on may appear lower compared to Standard Mode.* AI Energy Mode does not work with Game Mode.* Energy savings are based on internal test results and may vary depending on the content being displayed and surrounding brightness levels.
