Quad Core Processor 4K
Enhance everything you see and hear.
The processor removes video noise and creates more vibrant colour and contrast. Low resolution images are upscaled and reproduced at close to 4K quality. It also knows when, where, and how to improve sound, creating virtual surround sound for a more immersive and cinematic experience.

AI Brightness Control
A bright idea for better TV.
A light sensor measures the surrounding ambient light, then the processor finely adjusts tone mapping for optimal screen brightness. Smart dimming control and a pixel compensation algorithm improve contrast for better dark images. And HDR content is refined with brightness adjustments that transform darker scenes into ones with stunning contrast, detail, and color depth.

AI Sound
Sound that every genre deserves.
By learning from more than 17 million audio data points, the processor identifies voices, effects, and frequencies so it can then optimize the sound by genre for a more immersive experience.
