Our verdict

A large OLED Google TV where the screen itself produces the sound, aimed at film nights and PlayStation gaming. The stand still needs a wide surface, and the warranty period is short for a set this size.

Overview

Sony builds this BRAVIA OLED around pixel-level dimming, with the XR processor handling color, clarity and motion. The screen itself works as the speaker through Acoustic Surface Audio+, and Google TV runs the streaming apps.

Pixel-level dimming lets dark scenes hold deep black right beside bright highlights. Sound from the panel ties dialogue to the faces on screen without a soundbar. Listed power draw is high, and the manufacturer warranty covers only the first year.

Who it's for

Dim living rooms and dedicated movie spaces get the most from the OLED panel and the screen-as-speaker audio. Shoppers placing it on a short cabinet, or wanting extended panel coverage, should look at another model.

Pros and cons

Pros
  • Pixel-level dimming for deep black detail
  • Screen doubles as the speaker
  • Dolby Atmos and DTS Virtual:X decoding
  • PlayStation features and Game Menu listed
Cons
  • High listed power draw
  • Wide stand base needs a long surface
  • Only one year of manufacturer coverage
  • Peak brightness not listed

Performance notes

Each pixel controls its own light, so contrast holds in dark scenes without halos around bright objects. The XR processor sets how well lower resolution streams and fast motion are cleaned up. Audio rises from the panel surface, which places voices on the screen, while bass depth rests on the small low-frequency channel.
