Choose the Sony A90J if you prioritize excellent picture quality in dark rooms, superior contrast, and wide viewing angles, which is particularly important for movies and series watching. It's an OLED TV, so it offers deep blacks and vibrant colors, but is pricier and may not be as bright in well-lit rooms. The Sony X90K, an LCD TV, might be a better budget-friendly option with good performance in both dark and bright rooms. It's quite versatile for various content like sports, news, and gaming, and its brightness is more consistent in well-lit environments. However, its contrast and viewing angle may not match the A90J. Both support gaming features and have great upscaling for lower resolution content. Give Feedback

The Sony A90J (OLED) is excellent for movies & TV, while the Sony X90K (LCD) is good.
The Sony A90J has perfect contrast, is outstanding at displaying true black due to its black uniformity, and has strong local dimming, all contributing to a superior cinematic experience especially in dark scenes. The Sony X90K has good contrast and decent black uniformity, but with weaker local dimming and narrower viewing angles, which can affect the overall movie-watching experience when not seated directly in front of the TV. Both TVs offer good colors right out of the box and color volume, but the A90J's better handling of these elements enhances its prowess for movies and cinematic content.

The Sony A90J (OLED) is excellent for sports, while the Sony X90K (LCD) is good.
The Sony A90J OLED TV delivers excellent motion processing and response time, which are critical for fast-paced sports, as well as handling reflections superbly and offering wide viewing angles, making it ideal for group viewing situations. On the other hand, while the Sony X90K LCD TV also offers good motion processing and response time, its lower performance in reflection handling and narrower viewing angles make it less suited for watching sports in brightly-lit environments or with larger groups. Both TVs display good gray uniformity, but this factor is less impactful on the sports-viewing experience compared to other factors mentioned.

"In every meaningful department – motion control, contrast, edge definition, detail levels, you name it the A90J puts in a memorably accomplished shift. In fact, the Sony proves outstanding at handling on-screen motion of any and every kind. By the standards of television audio systems, the A90J is a notably punchy and genuinely dynamic performer."

"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."
