The Samsung Q80B may deliver a better gaming experience due to its lower input lag, making it suitable for fast-paced games. However, for watching movies in a dark room, the Sony X90K offers better performance with a higher dark room viewing score. Choosing between the two may come down to specific uses—gamers may prefer the Samsung, while movie enthusiasts, especially those watching in darker rooms, might lean towards the Sony. Keep in mind that both TVs are similar in price, so the decision should be based on the viewing environment and content preferences. Give Feedback

The Sony X90K (LCD) is good for movies & TV, while the Samsung Q80B (LCD) is only fair.
The Sony X90K provides a superior movie and cinematic TV experience compared to the Samsung Q80B mainly due to its higher contrast and better black uniformity, which enhance the depth and detail in dark scenes. Though both TVs offer good colors out of the box and color volume, the Q80B has a wider viewing angle, but its lower black uniformity and contrast make it less ideal for watching movies where dark scene performance is crucial.

The Sony X90K (LCD) is very good for news, talk, & other TV, while the Samsung Q80B (LCD) is good.
The Sony X90K is very good for watching news, talk shows, and other TV programs thanks to its superior upscaling capability, which enhances the picture quality of lower resolution content, and its high color accuracy right out of the box. While the Samsung Q80B also performs well in these regards, it does not quite match the Sony X90K's level of detail in upscaling and color reproduction, making it simply good for the same types of content.

The Sony X90K is considered better for bright room viewing as it has a higher HDR brightness, enhancing the viewing experience in rooms with a lot of natural light compared to the Samsung Q80B, which has a slightly lower HDR brightness. Both TVs have similar performance in handling reflections, which is fair, assisting in maintaining picture quality despite room brightness.

Although they have very similar scores, PerfectRec considers Sony X90K (LCD) to be good for sports, while the Samsung Q80B (LCD) is only fair.
The Samsung Q80B offers fair motion processing which is important for watching fast-paced sports, but it has wider viewing angles which makes it easier for groups to watch together. On the other hand, the Sony X90K provides better motion processing which helps in rendering smoother movement in sports, yet it has more limited viewing angles, possibly affecting off-angle viewing clarity.

The Samsung Q80B (LCD) and Sony X90K (LCD) are both very good for gaming.
The Samsung Q80B is outstanding for gaming because it has the best input lag performance, ensuring minimal delay between user input and on-screen action, and a very good response time, providing smooth motion in fast-paced games. The Sony X90K also boasts very good gaming capabilities with a strong response time for minimal blur during movement and good input lag performance, although not as optimal as the Samsung, it still supports a fluid gaming experience.

Although they have very similar scores, PerfectRec considers Sony X90K (LCD) to be very good for cartoons & animation, while the Samsung Q80B (LCD) is good.
The Samsung Q80B and Sony X90K both have good color performance straight out of the box and cover a wide color gamut, which is critical for accurately reproducing the vibrant colors often found in cartoons and animation. Although equally matched in color gamut, the Sony X90K is noted to have better gray uniformity and contrast, which can enhance the overall picture quality and make it very good for watching animated content compared to the Samsung Q80B which is just good.

"For most people its picture, sound, and price make it a midrange TV worth considering. HDR brightness was generally exceptional. Its viewing angles are shockingly good, among the very best we’ve seen recently from any non-OLED TV. For gamers input lag isn’t too shabby."

"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."
