The Sony X90K (LCD) is good for movies & TV, while the LG QNED90 (LCD) is only fair.
The Sony X90K performs better for movies and cinematic TV largely due to its superior contrast, local dimming, and black uniformity, which greatly enhances the viewing experience in dark scenes. While the LG QNED90 offers decent performance, it falls short compared to the X90K, especially in terms of contrast and blackness levels, making it less ideal for viewers who prioritize depth and detail in darker content.

Although they have very similar scores, PerfectRec considers Sony X90K (LCD) to be very good for bright room, while the LG QNED90 (LCD) is good.
The Sony X90K has a higher contrast ratio and handles reflections somewhat better than the LG QNED90, which means it can maintain better picture quality in a bright room. Both TVs offer very good SDR and HDR brightness, but the Sony might edge out in maintaining image quality under various lighting conditions due to its strengths in handling reflections and higher inherent contrast, benefiting color volume and gamut.

"When it comes to HDR brightness it has very bright highlights and impressive HDR. In terms of design the QNED90 looks beautiful. The TV did great with fast response times, excellent reactions and instant rendering of all our commands. If you look for a good performing premium 4K TV the QNED90 ticks all the boxes."

"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."
