Our take on the Sony 77" 4K XR-77A80J Smart TV

The Sony XR-77A80J is a 77-inch 4K OLED TV from Sony's 2021 BRAVIA XR line. Its OLED panel delivers per-pixel contrast with true blacks, and the Cognitive Processor XR drives Sony's picture processing, including XR Triluminos Pro color and Acoustic Surface Audio, which vibrates the panel itself to produce sound. It runs Google TV with Netflix and other apps built in, and includes ATSC tuner, HDMI 2.0 inputs and wall-mount support. It suits movie and series viewers who want a large, cinematic OLED and don't need the brighter panel or HDMI 2.1 gaming features of the step-up A90J.

Questions and answers

Is the A80J worth it over the A90J?

The A90J is brighter and has a sturdier stand, but the A80J shares the OLED panel type and XR processing. If you watch mostly in dim rooms, the A80J covers the essentials.

Does it support 4K at 120Hz for consoles?

Its HDMI ports are 2.0, so 4K is limited to 60Hz. It is fine for casual console play but not for high-frame-rate gaming.

What is Acoustic Surface Audio?

Actuators vibrate the OLED panel itself to produce sound, so audio comes from the screen rather than separate drivers. It gives clearer dialogue than most built-in speakers.

Can it be wall mounted?

Yes, it is wall-mountable and its slim panel suits a flush wall install. A compatible VESA mount is needed.

What apps does it include?

It runs Google TV with Netflix and other major streaming apps built in, plus an ATSC tuner for over-the-air channels.
