The Sony X90K is an LCD TV that strikes a balance between price and performance, offering good overall picture quality for various contents. It performs very well in bright rooms and has very good quality when watching sports, cartoons, and news. Gaming performance stands out thanks to its response time and low input lag. However, the viewing angle is limited, making it less ideal if you're watching from wide angles. If a rich audio experience is important, note that it does not have great built-in speakers, so you might consider purchasing a soundbar or external speakers to enhance the sound. Give Feedback

News, Talk & Reality TV:
The Sony X90K excels with upscaling lower resolution content, which is crucial for watching regular TV broadcasts like news and talk shows, ensuring a sharp image even from non-HD sources. Additionally, its high SDR brightness and good color reproduction provide a clear and vibrant picture in most lighting conditions.
PerfectRec’s gaming score measures a TV's performance when it comes to playing video games. It is based on several factors that can significantly impact the quality of the gaming experience, including screen response time, input lag, and refresh rate. Screen response time is a critical factor that determines how quickly the TV can transition from one color to the next, while input lag measures the delay between the gaming console output and the TV display. Refresh rate refers to the number of times per second that the TV displays a new frame, which can impact the smoothness of the gaming experience. The gaming score also takes into account two other features: local dimming in gaming mode, which can enhance contrast and picture quality, and black frame insertion, which can reduce screen brightness and create a smoother gaming experience.
Cartoons & Animaton:
The Sony X90K is acknowledged as very good for watching cartoons and animation because it displays colors accurately straight out of the box, ensuring vibrant and true-to-life hues without the need for calibrations. Furthermore, it possesses a good color gamut and color volume, contributing to rich and consistent color reproduction across a wide range of tones, which is vital for the varied palettes often found in animated content.
Bright Room:
The Sony X90K is very good at handling bright room conditions because it has high SDR and HDR brightness which means the screen can remain visible and clear even in well-lit environments, and its ability to handle reflections is fair, ensuring that the amount of glare on the screen is not too distracting. While its contrast, color volume, and color gamut are important for picture quality, it's the brightness levels and reflection handling that are more critical when it comes to maintaining a good viewing experience in bright rooms.
Overall Picture:
PerfectRec developed this proprietary score designed to provide an overall assessment of a display's visual performance. It is a comprehensive metric that takes into account many quantitative measures of picture quality, including: contrast ratio, color gamut, color volume, color accuracy, local dimming, gray uniformity, black uniformity, viewing angle, reflections (glare) and color calibration. By combining multiple factors, this score offers a more nuanced and comprehensive evaluation of a display's capabilities than a single factor.
Movies & TV shows:
PerfectRec’s movies & cinematic TV score takes into account the most important TV features for cinematic content. Our score considers the following factors:color gamut, color volume, out-of-the-box color accuracy, local dimming and black uniformity. We also factor in gray uniformity and viewing angles to a lesser degree.
PerfectRec’s sports score prioritizes response time and refresh rate as the most important factors to ensure clear images of fast-moving scenes. In addition, we consider gray uniformity, which ensures that the turf looks the same across the whole screen, reflections, to avoid distracting ambient light from the action, and viewing angles and brightness, to avoid color distortion and washed-out images, especially when not seated directly in front of the TV.

Al Griffin | December 2022
"As Sony’s next-to-flagship LCD TV, the X90K series delivers impressive performance for the price. The XR90K had fairly accurate out-of-box color. The TV’s multi-position stand lets you either set the screen flush with any stand its mounted on or elevate it to clear space for a soundbar. With the latter option, you get around 3 inches of clearance enough to accommodate most soundbars. The X90K’s excellent suite of gaming features ranks it up there with the best 120 Hz 4K TVs."
