Sony K77XR80PU 77" 4K OLED TV – Cognitive Processor XR – Smart Google TV

Experience television the way the director intended with the Sony K77XR80PU 77" 4K OLED TV – a masterpiece of picture quality powered by Sony's revolutionary Cognitive Processor XR on a massive 77-inch screen. Designed for UK homes seeking the absolute best in home cinema, this premium OLED television delivers perfect blacks, infinite contrast, and intelligent picture processing that understands how humans see and hear, creating an incredibly immersive and emotionally engaging viewing experience.

The 77-inch OLED panel delivers the perfect black levels and infinite contrast that only self-emissive OLED technology can provide. Each of the millions of pixels emits its own light, turning off completely to achieve absolute black. This creates extraordinary depth, realism, and detail in dark scenes that other technologies cannot match – watching a horror film, space epic, or night-time drama on this screen is transformative. The massive 77-inch size fills your field of vision for a truly cinematic experience.

The Cognitive Processor XR is Sony's most advanced picture processor. Unlike conventional AI that merely analyses and enhances individual picture elements, the Cognitive Processor XR cross-analyses entire scenes, understanding how humans naturally focus on certain points. It then enhances every element – colour, brightness, contrast, and detail – working together in harmony for a natural, lifelike image that mimics human vision. This results in incredibly realistic images that draw you into the content.

The XR OLED Contrast Pro technology enhances brightness in OLED panels without compromising black levels. This allows the XR80PU to deliver more impactful HDR performance than standard OLEDs, with brilliant specular highlights – sun glints, explosions, reflections – standing out against perfect blacks for stunning realism. On a 77-inch screen, this contrast and brightness combination is particularly striking.

The XR Triluminos Pro technology accesses billions of accurate colours, reproducing every shade and hue with precision. Skin tones are natural, landscapes are vivid, and every colour is rendered with the subtlety the creator intended. The result is exceptionally natural, lifelike imagery that avoids the oversaturated look of lesser TVs, even at this massive scale.

The 4K Ultra HD resolution (3840 x 2160) delivers four times the detail of Full HD, while the XR 4K Upscaling uses the Cognitive Processor to reconstruct and refine lower-resolution content to near-4K quality. Streaming, broadcast TV, and older content look sharper and more detailed than you thought possible – essential on a 77-inch screen where lower-resolution content can look soft.

The XR Smoothing technology eliminates colour banding and posterisation, creating smooth, natural gradients in skies, sunsets, and other areas where subtle colour transitions matter.

For gamers, the XR80PU delivers exceptional performance. 4K at 120Hz (via HDMI 2.1), VRR (Variable Refresh Rate), and ALLM (Auto Low Latency Mode) provide ultra-smooth, tear-free, responsive gameplay. The Game Menu brings all game settings into one place, with features like Motion Blur Reduction and Black Equaliser. Input lag is extremely low, making this OLED a top choice for PlayStation 5 – features like Auto HDR Tone Mapping and Auto Genre Picture Mode optimise settings automatically when connected to a PS5, creating the ultimate gaming experience.

The Cognitive Processor XR also enhances sound with Acoustic Surface Audio+ technology. The entire screen acts as a speaker, with actuators vibrating to produce sound that follows the action on screen. This creates a unique soundstage where dialogue comes directly from the actor's mouth, and effects move across the screen in sync with the picture – no separate soundbar required for impressive audio, though one can be added for even greater immersion. The soundstage is wide and immersive, matching the massive screen.

Dolby Vision, HDR10, and HLG support ensure compatibility with all major HDR formats. Dolby Vision optimises scene-by-scene metadata for the most accurate HDR presentation possible on Netflix, Disney+, and Apple TV+. IMAX Enhanced certification ensures optimal playback of IMAX content.

The Google TV platform (Sony's smart interface) brings together content from your streaming apps into a personalised home screen. Access all major UK streaming services: BBC iPlayer, ITVX, All 4, My5, Netflix, Disney+, Amazon Prime Video, Apple TV+, YouTube, and more. Google Assistant is built-in, allowing voice search, hands-free control, and smart home device management.

The BRAVIA Core streaming service provides access to Sony Pictures movies in high bitrate 4K UHD, with Pure Stream technology delivering near-lossless quality – the ideal way to show off this TV's capabilities.

The minimalist, slim design with narrow bezels focuses attention on the picture. The flush surface mount keeps the TV close to the wall for a gallery-like appearance. A table-top stand is included, offering two placement options – standard or soundbar-friendly elevated position.

Connectivity includes 4 x HDMI (2 x HDMI 2.1 with 4K at 120Hz), 2 x USB, Ethernet, Wi-Fi, Bluetooth, and optical audio out. The eARC port allows lossless Dolby Atmos audio to pass to a compatible soundbar for the ultimate home theatre setup.

For UK homeowners seeking reference-quality picture and sound on a massive 77-inch screen, with Sony's renowned Cognitive Processor XR and perfect OLED black levels, the Sony K77XR80PU 77" 4K OLED TV delivers a truly cinematic experience that brings every movie, show, and game to life.
