About the Sony BRAVIA XR-48A90K
Premium OLED quality in a small package
Premium OLED quality in a small package
With self-lighting pixels that can display absolute black, OLED TVs are stunning to behold. In fact, one of the only complaints I've seen about them is their limited size range, especially on the smaller end. Well, Sony aims to fill that gap with the 48" BRAVIA XR-48A90K.
This set's compact size makes it a great choice as a gaming display or for general use in smaller rooms. Powered by Sony's Cognitive Processor XR, it delivers accurate color and intelligently controlled contrast for realistic depth and sharply defined details, even in areas of shadow or glare.
Smart processing improves picture quality
The XR-48A90K's Cognitive Processor XR takes conventional Artificial Intelligence a step further by emulating the way our brains think and respond when we see and hear things. It cross-analyzes individual picture elements and quickly identifies the human focal point, so that it can immediately enhance each detail of that area. Instead of applying generic changes to the entire frame, it recognizes how individual parts of the whole interact with each other and makes precise adjustments to create a more natural picture.

The two-way stand has a low-profile setting (shown) and a raised option to accommodate a sound bar.
Better sound, too
The ‘A90K's XR processor also contributes to richer, more involving sound. Its 3D Surround Upscaling technology can create a heightened Atmos-like soundfield no matter what the source.
Acoustic Surface Audio+™ technology tracks sound effects and dialogue and matches them with the on-screen action, creating an even more immersive experience. Instead of the tiny — often down-firing — speakers that most TVs have, the ‘A90K uses actuators on the back to send vibrations through the screen to produce sound from its entire surface.
And if you still want more, Acoustic Center Sync synchronizes the TV's built-in speakers with compatible Sony sound bars for even better sound.
Google TV simplifies streaming
The XR-48A90K includes the Google TV smart app platform which consolidates a wide range of streaming services into a single user interface. Watch an episode of Ted Lasso on Apple TV followed by Station Eleven on HBO Max all from one watchlist, without having to dig around in individual apps.
And if you're feeling really lazy, you can simply ask the Google Assistant to pull up a show or movie. You can also adjust the volume, change channels or inputs, and control other basic TV functions using your voice.
A top-notch display for gaming
The 48" XR-48A90K is an excellent match for your PC or next-gen console, with a dedicated Game Mode that delivers an input lag as low as 8.5ms. It supports Auto Low Latency Mode (ALLM), 4K at 120Hz, and enhanced Audio Return Channel (eARC) right out of the box. A future firmware update will also offer Variable Refresh Rate (VRR) for smooth graphics without frame tearing or stuttering. And if you've got a PS5, you'll benefit from Auto HDR Tone Mapping for more accurate detail and color.
