If you're looking for a TV that's friendlier on the budget, the LG NANO75 has a lower price point and decent performance, especially for watching sports and regular TV shows. It has a wide viewing angle which is great for watching with a group. On the other hand, the Sony X90K, while more expensive, offers significantly better overall picture quality and audio, making it a superior choice for movies, gaming, and viewing in both bright and dark rooms. It also has support for advanced features like higher refresh rate and better performance as a monitor. Basically, if you prioritize higher quality for a wider range of content and uses, and don't mind spending more, go with the Sony X90K. If you prefer to save money and mainly watch sports or daytime TV shows, the LG NANO75 may suffice. Give Feedback

The Sony X90K (LCD) is good for movies & TV, while the LG NANO75 (LCD) is poor.
The Sony X90K provides a better movie-watching experience with superior contrast, local dimming, and black uniformity that enhance deep blacks and sharp picture quality, whereas the LG NANO75 suffers due to its lower contrast, lack of local dimming, and poorer black uniformity, which can result in a less immersive and flatter image.

Although they have very similar scores, PerfectRec considers Sony X90K (LCD) to be good for sports, while the LG NANO75 (LCD) is only fair.
The Sony X90K is considered better for watching sports because it has superior response time and motion processing compared to the LG NANO75, meaning less blur during fast action. While the LG NANO75 offers better viewing angles, it falls short in handling reflections and motion, making the Sony X90K more suited for dynamic sports content in various lighting conditions.

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."
