Excellence on Screen

α7 AI Processor 4K Gen6

Evolution at Its Core

Enter the world of α-realism¹. A portal to new universes and the sensation of feeling like you're really there. Be the main character surrounded by the exceptional picture and sound refinements of α7 AI Processor 4K Gen6.

AI Super Upscaling

The AI processing system uses AI Noise Reduction and AI Super Resolution to classify images and remove noise based on their category. Then, deep learning algorithms enhance faces and objects to make them look more defined, expressive, and multi-dimensional without appearing artificial.

OLED Dynamic Tone Mapping

OLED Dynamic Tone Mapping refines what's in the frame by applying the optimal tone curve for more natural HDR, contrast, and detail.

Sound that surrounds you

Virtual 5.1.2 Surround Sound puts you at the heart of the story. Hear fighter jets zooming overhead, footsteps rustling behind you, and the swell of the orchestra as it reaches the crescendo.

A video opens showing an aerial shot of the remote control. A blue circle appears over the sensor. The scene pans out to show the remote control on a coffee table in a gray room. Blue soundwaves emit from the TV, and an image fills the screen showing a person kayaking over choppy waves. The blue sound waves reach the remote control, and waves depicting sound bounce from the wall, and then a blanket of sound covers the room.

SELF-LIT OLED

No Backlight Necessary

A video of a TV's layers with a starry nighttime landscape photograph on the main OLED display. The backlight disappears, and the polarizer, color filter, and OLED come together to produce an image so bright that it reflects below the TV like on water.

Infinite Contrast

With deep dark blacks that can only be achieved by self-lit pixels, bold contrast reveals details your eyes usually miss with crisp, defined visuals.

100% Color Fidelity & 100% Color Volume

With 100% color fidelity and volume, colors are displayed exactly like the original, with rich tones in both bright and dark environments.

*Screen images simulated.

***Display Color Gamut Volume (CGV) is equivalent or exceeds the CGV of the DCI-P3 color space as verified independently by Intertek.

TV and Soundbar in Harmony
