If you frequently watch movies and series in darker environments, the Sony X90K is a better choice due to its superior dark room performance. On the other hand, the Samsung QN85B has a brighter display which is more suitable if you will watch TV in a well-lit room. The Samsung also offers a slightly better gaming experience, so if gaming is important to you, that might be the way to go. However, the Sony X90K tends to be more expensive but offers better overall picture quality and is known to have a more reliable quality control. Both TVs support major HDR formats, but only the Samsung supports HDR10+. Neither TV has great built-in speakers, so consider investing in a sound system for either model. Give Feedback

The Sony X90K (LCD) and Samsung QN85B (LCD) are both good for movies & TV.
The Samsung QN85B is praised for movies and cinematic TV thanks to its excellent local dimming and very good contrast, which enhance deep blacks and overall picture quality, although its black uniformity is a bit weaker. On the other hand, the Sony X90K delivers a very good movie-watching experience with its superior contrast and better black uniformity, ensuring more consistent deep blacks, but has a lower local dimming performance which might affect the precision of illuminating specific areas during dark scenes. Both TVs offer good colors out of the box and color volume, although the Samsung has a slight edge in viewing angles, which could be significant for wide seating arrangements.

The Sony X90K (LCD) and Samsung QN85B (LCD) are both good for sports.
The Samsung QN85B is well-suited for sports due to its quick response time and wide viewing angles, ensuring clear images even during fast movements and from different seating positions; however, its reflection handling is somewhat less effective than some other TVs. In contrast, the Sony X90K excels with its superior motion processing which reduces blur during fast action, and excellent response time, but it has narrower viewing angles, making it less ideal for large groups spread out across a room.

What Hi-Fi?
John Archer | February 2023
"Particularly key to this is the fact that black levels are unusually good, on a level we haven’t seen from any IPS TV before. Build quality is impressive too, with a gleaming silver metallic frame and stand, and enough heft to suggest plenty of quality innards. High dynamic range content jumps off the screen with enough luminosity and intensity to really sell what makes HDR special."

"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."
