The LG NANO90 is more expensive but offers a better gaming experience, stronger overall picture quality, and superior performance in bright rooms. It also has a higher refresh rate and more HDMI ports, which could be important for connecting multiple devices. On the other hand, the Sony X77L is less expensive and still provides a good experience for sports content and has better color accuracy out of the box. However, it falls short in darker room settings and has a lower refresh rate. If budget is a primary concern and you primarily watch sports or regular TV shows, the Sony could suffice. But if gaming and use in a brightly lit room are important, you may find the LG to be worth the extra investment. Give Feedback

The LG NANO90 (LCD) is very good for gaming, while the Sony X77L (LCD) is poor.
The LG NANO90 excels in gaming due to its good response time and very good input lag, minimizing motion blur and delay in displaying content from gaming devices. In contrast, the Sony X77L, despite having very good input lag, offers poor response time, which can result in more noticeable blur during fast-paced games.

The LG NANO90 (LCD) and Sony X77L (LCD) are both only fair for bright room, though the LG NANO90 (LCD) is somewhat better.
The LG NANO90 has better handling of reflections and HDR brightness than the Sony X77L, making it more suitable for bright rooms; however, the Sony X77L offers a wider color gamut and color volume, which may be better for vibrant content despite its fair reflection handling and lower HDR brightness.

The LG NANO90 (LCD) and Sony X77L (LCD) are both poor for movies & TV.
The LG NANO90 has poor colors out of the box, which compromises the initial viewing experience, and both its contrast and local dimming are not ideal, leading to less impressive dark scenes and a weaker cinematic feel. Meanwhile, the Sony X77L exhibits very good colors out of the box, but suffers from even lower contrast and poor local dimming capabilities, along with subpar color volume, affecting its overall ability to display deep blacks and a rich, vibrant picture for movies and cinematic content.

The Sony X77L (LCD) and LG NANO90 (LCD) are both only fair for sports.
The LG NANO90 offers very good reflections handling and good response time, making it suitable for watching sports in well-lit rooms and ensuring smooth motion; however, it shows weaker performance in motion processing and has a merely fair viewing angle, which might be a concern in wider seating arrangements. On the other hand, the Sony X77L has fair reflections handling and poor response time, resulting in less optimal performance in bright rooms and less smooth motion during fast sports, but it outperforms the LG in gray uniformity and viewing angles, enhancing the visual consistency across the screen and viewing experience from different angles.

Although they have very similar scores, PerfectRec considers Sony X77L (LCD) to be only fair for cartoons & animation, while the LG NANO90 (LCD) is poor.
The LG NANO90 (LCD) performs poorly for cartoons and animation due to its fair color gamut and color out of the box scores, meaning its ability to produce a wide range of colors and accurately display them without adjustment is limited. The Sony X77L (LCD), while still not excellent, is considered fair because, despite having a poor color gamut, its very good colors out of the box score indicates it can display accurate colors right away which is typically more appealing for animated content.

The LG NANO90 (LCD) and Sony X77L (LCD) are both only fair for news, talk, & other TV.
Both the LG NANO90 and the Sony X77L LCD TVs are acceptable options for watching news and TV programs, with the LG NANO90 offering very good upscaling and colors straight out of the box, whereas the Sony X77L is slightly behind with good performance in these areas but is a more recent model which could indicate improved technology or features. Both models deliver fair SDR brightness, which is important when viewing in well-lit rooms, and both provide a good enough color gamut and volume for a satisfactory viewing experience without the need for immediate calibration.

"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."
