This 65-inch LCD (LED) 4K UHD TV from Sony has full-array local dimming, 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 that its HDR performance was effective, but its viewing angle was limited.

The Sony X90K is great for most uses. It's great for watching SDR or HDR movies because it displays deep blacks, makes colors look vivid, and has a good local dimming feature, but there's some blooming around bright objects. It's also good for watching shows or sports in bright rooms with a couple of lights around, but it's not as good if you place it opposite a bright window. It has a narrow viewing angle that makes the image looks washed out from the sides. Lastly, it's great for gaming because it has HDMI 2.1 bandwidth for high-frame-rate gaming, variable refresh rate support, a quick response time, and low input lag for a responsive gaming experience.

The Sony x90k is loaded with features.
