The LG NANO90 is priced mid-range and provides a better gaming experience than the Sony X80K but may cost more. It has superior dark room performance, making it a better choice if you prefer watching in dimly lit environments. On the other hand, the Sony X80K, priced lower mid-range, is more cost-effective and offers better performance for watching sports, due to its reflection handling which is advantageous for bright room viewing. Both models support the same HDR formats and have similar input lag for gaming. If budget is a constraint and sports or bright room viewing are priorities, the Sony X80K could be preferable, whereas the LG NANO90 is more suited for gaming enthusiasts and those valuing better contrast in dark rooms.

The Sony X80K (LCD) is good for sports, while the LG NANO90 (LCD) is only fair.
The LG NANO90 displays sports with less clarity due to its adequate but not exceptional motion processing and response time, coupled with weaker reflection handling which can be troublesome in bright rooms. In contrast, the Sony X80K provides a better experience for sports viewing with superior motion clarity and excellent response time, wide viewing angles, and good reflection handling, making it more suitable for group watching in various lighting conditions.

The LG NANO90 (LCD) and Sony X80K (LCD) are both only fair for bright room, though the LG NANO90 (LCD) is somewhat better.
The LG NANO90 delivers good SDR brightness that makes it suitable for bright rooms but has a reflection handling capability that is only fair, meaning it can struggle with direct light sources. In contrast, the Sony X80K also offers fair performance in bright rooms but falls behind with just fair reflection handling and lower SDR brightness, which may not be as effective in very bright settings.

The LG NANO90 (LCD) and Sony X80K (LCD) are both poor for movies & TV.
The LG NANO90 struggles with movies and cinematic TV due to its poor performance in contrast and local dimming, coupled with less than ideal black uniformity, affecting dark scene reproduction. Similarly, the Sony X80K, despite better colors out of the box, suffers from poor contrast and lacks any local dimming, also leading to subpar black levels and less immersive viewing in darker environments.

"Here we have HDR pictures that look bright, but also manage to typically hit decently deep black levels.WebOS continues, though, to be one of the easiest to use. Connections are strong for a mid-range TV. Native 4K pictures look crisp and detailed."

"The Sony Bravia X80K is an inexpensive LCD TV that turns out pleasing visuals and is armed with a number of other desirable features. Sony’s robust internal processing, results in generally better picture quality than you’ll usually get for this price. In practice, the X80K is satisfying to watch. You’re not going to get as sumptuous a picture as you may with other TVs from Sony or other companies, but we didn’t encounter anything that looked bad on it."
