The LG NANO90 is a midrange-priced LCD TV that offers a good gaming experience and performs well in bright rooms, but it struggles in dark room settings. It's significantly less expensive than the Sony A90J. On the other hand, the Sony A90J is a high-end OLED TV with excellent overall picture quality, especially in dark rooms, and is well-suited for movies and gaming. However, it is typically much more expensive than the LG NANO90 and may not perform as well as the LG in very bright rooms. If budget isn't a concern and you prioritize picture quality and dark room performance, go for the Sony A90J. If you're looking for a cost-effective option that is still versatile for gaming and bright environments, the LG NANO90 is a suitable choice. Give Feedback

The Sony A90J (OLED) is very good for cartoons & animation, while the LG NANO90 (LCD) is poor.
The LG NANO90 LCD TV exhibits poorer performance in cartoons & animation primarily because it does not display colors as accurately out of the box and has a limited color gamut compared to the Sony A90J OLED, which shows rich and accurate colors immediately upon use and supports a wider color gamut, essential for vibrant and varied hues. Additionally, the OLED technology of the Sony A90J provides better color volume and contrast, enhancing the visual experience, especially in animated content where these elements are crucial.

The Sony A90J (OLED) is very good for news, talk, & other TV, while the LG NANO90 (LCD) is only fair.
The Sony A90J provides exceptionally good upscaling quality and impressive colors right out of the box, which enhances the clarity and vibrancy when watching news, talk shows, and TV programs. In contrast, the LG NANO90 has weaker upscaling capabilities and color performance, which could result in less detailed and less vivid picture quality for these types of content.

"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."

"In every meaningful department – motion control, contrast, edge definition, detail levels, you name it the A90J puts in a memorably accomplished shift. In fact, the Sony proves outstanding at handling on-screen motion of any and every kind. By the standards of television audio systems, the A90J is a notably punchy and genuinely dynamic performer."
