The LG QNED90 is a higher-priced TV that offers superior overall picture quality, making it suitable if you are looking for rich visuals in your movies and series. It also has a higher performance in gaming thanks to a faster response time and support for advanced gaming features, which could be a major plus if you're an avid gamer. This TV is also better suited for bright rooms. On the other hand, the Sony X77L is less expensive, and while it offers good performance across various types of content including sports and animation, its picture quality in dark rooms is notably lower. This could be a drawback if you often watch TV in low-light conditions. Its sound quality is also lesser compared to the LG. If budget is a significant factor, and you mostly enjoy TV shows and sports in rooms that aren't very dark, the Sony might be more appealing. Give Feedback

The LG QNED90 (LCD) is only fair for movies & TV, while the Sony X77L (LCD) is poor.
The LG QNED90 offers a better movie and cinematic TV experience than the Sony X77L because it has higher contrast, more effective local dimming, and superior black uniformity, which are crucial for deep and consistent images in dark scenes. While both TVs have decent viewing angles and color accuracy out of the box, the LG's greater color volume and better gray uniformity contribute to a more vibrant and uniform picture.

The LG QNED90 (LCD) is very good for gaming, while the Sony X77L (LCD) is poor.
The LG QNED90 stands out for gaming due to its good response time and very good input lag, which means it reacts quickly to your actions and keeps gameplay smooth and responsive. In contrast, the Sony X77L has poor response time, which can lead to longer delays between your input and the action on screen, making it less ideal for fast-paced gaming despite its very good input lag.

The LG QNED90 (LCD) is very good for news, talk, & other TV, while the Sony X77L (LCD) is only fair.
The LG QNED90 is better for watching news and TV programs because it has ‘Very Good’ upscaling and SDR brightness, which ensures detailed images and adequate brightness for day-to-day content. In contrast, the Sony X77L is deemed fair due to its weaker performance in upscaling and a limited color gamut, meaning it might not present such content as clearly or vividly.

The Sony X77L (LCD) and LG QNED90 (LCD) are both only fair for sports.
The LG QNED90 has good motion processing but fair handling of reflections, while the Sony X77L has better motion processing but also fair reflections handling, which may affect the sports watching experience, particularly in well-lit environments. Both TVs offer a good viewing angle, but the gray uniformity on the Sony is slightly better, which can contribute to a more uniform image during sports scenes with large fields of uniform color.
