This 77-inch OLED 4K UHD TV from Sony is internet enabled, and uses the "Google TV" operating system. It includes a built-in Google Assistant virtual assistant. Sony claims this model will also work with external Google Assistant, Amazon Alexa, and Apple Siri HomeKit devices. It also includes an ATSC 3.0 tuner for receiving "Next-Gen TV" signals. CR's tests found it had generally Excellent picture quality, a very wide viewing angle, but the HDR performance had limited effectiveness.

The Sony A80K is excellent for most uses. It performs best in dark rooms while watching movies because it displays deep blacks without any blooming in dark scenes. It's excellent for HDR because of that dark room performance and the fact that it displays a wide range of colors, but its HDR brightness isn't high enough for the best HDR experience. It's great for watching TV shows and excellent for sports in well-lit rooms thanks to its wide viewing angle and incredible reflection handling, but it doesn't get bright enough to fight a ton of glare. Lastly, it's fantastic for gaming as it has variable refresh rate (VRR) support with HDMI 2.1 bandwidth, a quick response time, and low input lag.
