On the other hand, if darker room performance is vital, you might not see a big difference between the two. Also, note that neither TV excels in sound quality and might benefit from external speakers. Give Feedback

The Sony X85J (LCD) is only fair for movies & TV, while the LG NANO90 (LCD) is poor.
The LG NANO90 has a lower contrast and less effective local dimming that can make dark scenes in movies less impressive, and its black uniformity isn't as good as some viewers might prefer for cinematic content. Meanwhile, the Sony X85J offers a much better contrast making it more suitable for movies where dark scenes are commonly featured, but its poor viewing angles may reduce the picture quality when not sitting directly in front of the screen.

The Sony X85J (LCD) is very good for cartoons & animation, while the LG NANO90 (LCD) is poor.
The LG NANO90 displays cartoons and animations poorly due to its less accurate colors out of the box and a fair color gamut, which means it cannot reproduce a wide range of colors vibrantly. In contrast, the Sony X85J offers an excellent experience with accurate colors out of the box and good color volume, ensuring that animations are shown with rich, well-saturated hues.

The Sony X85J (LCD) is very good for news, talk, & other TV, while the LG NANO90 (LCD) is only fair.
The Sony X85J is considered very good for watching news, talk shows, and other TV programs due to its higher SDR brightness and excellent colors out of the box, which provide a clearer and more vibrant viewing experience. However, the LG NANO90 is only considered fair in these aspects with good SDR brightness and poor colors out of the box, meaning it offers a less optimal viewing experience for daily content compared to the Sony model.

Although they have very similar scores, PerfectRec considers Sony X85J (LCD) to be good for sports, while the LG NANO90 (LCD) is only fair.
The Sony X85J LCD TV provides a better sports watching experience thanks to its excellent motion processing, which means it can handle fast-moving action more smoothly, while LG NANO90's motion processing is considered good but not on par with the Sony. Additionally, whereas the LG NANO90 has a very good handling of reflections, making it suitable for well-lit rooms, the Sony X85J has a poorer performance in this aspect, which can be a downside if you often watch TV in a bright environment.

Although they have very similar scores, PerfectRec considers LG NANO90 (LCD) to be very good for gaming, while the Sony X85J (LCD) is good.
The LG NANO90 is rated higher for gaming, primarily because it has very good input lag, crucial for quick reaction times in games, and a good response time, which reduces motion blur. The Sony X85J, while also suitable for gaming, doesn't match the LG NANO90's performance in these critical areas.

Although they have very similar scores, PerfectRec considers Sony X85J (LCD) to be good for bright room, while the LG NANO90 (LCD) is only fair.
The Sony X85J outperforms the LG NANO90 in a bright room primarily due to its superior reflections handling, which reduces the impact of ambient light on the screen. Additionally, while both TVs offer good SDR and HDR brightness, the Sony X85J's higher contrast ratio contributes to better color volume and gamut, enhancing the overall viewing experience in well-lit environments.
