Sony XR8B Overview

With a sleek design, cinematic audio, and stunning visuals, the Sony BRAVIA XR8B 77" 4K HDR Smart OLED TV makes the perfect centerpiece for your main TV viewing area. An incredibly accurate picture is created by millions of self-lit pixels, precisely controlled to produce pure black, with high brightness, and billions of shades of color.

Connect HD and UHD devices via HDMI 2.1 inputs with advanced gaming features like VRR and ALLM. The built-in Google TV OS provides access to streaming options with your favorites and frequently watched shows brought together in one convenient home screen. For audio, the screen is the speaker; delivering clear sound, aimed at the listener. Featuring Acoustic Surface Audio+, the integrated 2.1-channel speaker system follows the action on screen for immersive, theater-like quality. Additionally, Acoustic Center Sync allows the TV to be used as a center channel with compatible BRAVIA home theater models.

Accurate OLED Lighting
Over 8 million self-lit pixels are precisely controlled to produce pure black with high brightness. With a high luminance panel and temperature sensor, this TV precisely controls light for brighter pure black pictures.
Real-World Color
See the world's colors with all the vibrance of real life. Access over a billion accurate colors, with subtle differences in hue and saturation that reveal natural shades in every detail.
XR Clear Image Processing
Bring back lost detail with reduced noise and see all your HD and digital content upscaled to near-4K resolution with XR Clear Image. See the authentic features of people's faces, identify every blade of grass, and marvel at the precise texture of buildings and scenery. Upscaled, simulated, and enhanced 4K images will vary based on source content.
XR OLED Motion
Enhance fast moving content like live sports and action-packed movies with Sony's XR OLED Motion. This advanced processing combats blur and judder by analyzing on-screen motion and precisely controls every frame to ensure picture quality stays smooth, bright, and clear.
Powerful TV Processing
Watch everything with lifelike picture quality, powered by the intelligent XR Processor. Hundreds of thousands of individual on-screen elements are processed and enhanced in real-time, boosting color, contrast, and clarity.
Studio Calibrated Picture
With decades of film production experience, Sony strives to faithfully reproduce the creator's vision with Studio Calibrated Picture Modes. Netflix Adaptive Calibrated Mode brings studio-quality mastering home, with brightness automatically adjusted to your room conditions. With Prime Video Calibrated Mode, see movies, shows, and even live sports the way the filmmakers and broadcasters intended. SONY PICTURES CORE Calibrated Mode (formerly BRAVIA CORE) brings studio-quality picture mastering to your living room.
Acoustic Surface Audio+
With Acoustic Surface Audio+, actuators behind the TV panel turn the entire screen into a speaker producing a wider, elevated soundstage, enabling audio to follow the action on screen. Voice Zoom 3 intelligently controls dialogue so that every word in a scene is always loud and clear. With support for Dolby Atmos, DTS:X, and 3D Surround Upscaling, everything you watch gets the surround sound treatment.
Center Speaker Sync
Pair your BRAVIA TV with compatible BRAVIA Theater models for the ultimate cinema-like experience at home. Acoustic Center Sync pairs the TVs speakers with the sound system, reinforcing the center channel for clearer, fuller dialog. When connected, easily control the sound settings on the TV's Quick Settings menu, making it easy to adjust volume and sound field with a single remote.

Awesome OLED! I can not see the difference between this tv and the Bravia 8 I saw at the store. Bought this sight unseen online and performs best at night but also handles reflections well in the day and sounds great. Most realistic colors/picture in OLED that I found comparing other brands. Love it! Thanks Sony!
