For watching movies, TV series, and news, the LG UP7000 and Sony X77L are quite similar, although the Sony X77L has a slight edge in picture quality. If gaming is important to you, the Sony X77L performs slightly better, especially for sports content. In dark rooms, neither TV is outstanding, but the LG is weaker with a poorer contrast that might not deliver deep blacks. The LG UP7000 tends to be less expensive, but if a brighter room performance and overall quality control are more critical for you, the Sony X77L is marginally better, although it comes at a higher cost. Both TVs have a lower midrange price, so the choice likely comes down to whether you prioritize a lower price or slightly better performance in specific viewing scenarios. Neither TV excels in handling bright rooms well, but the Sony is somewhat more capable in this aspect. However, if you plan to use the TV as a monitor, the LG UP7000 has a better score for that use.

The Sony X77L (LCD) and LG UP7000 (LCD) are both only fair for sports.
When watching sports, the LG UP7000's fair performance is due to its decent response time and motion processing, but poor handling of reflections and narrow viewing angles may diminish the experience. On the other hand, the Sony X77L also offers fair sports viewing due to its satisfactory gray uniformity, but like the UP7000, it struggles with wider viewing angles and reflection handling, which are important in well-lit rooms.

The Sony X77L (LCD) and LG UP7000 (LCD) are both poor for gaming.
The LG UP7000 and the Sony X77L are both poor for gaming primarily due to their inadequate response times, which can lead to motion blur during fast-paced games. While the Sony X77L has a very good input lag, making it responsive to gaming inputs, its response time is poor, which can still detract from the gaming experience; the LG UP7000 has poor response time as well, but it features best input lag, ensuring minimal delay between user actions and on-screen reactions.

Although they have very similar scores, PerfectRec considers Sony X77L (LCD) to be only fair for news, talk, & other TV, while the LG UP7000 (LCD) is poor.
The LG UP7000 shows weaknesses in upscaling and offers poor color accuracy out of the box, resulting in a less vibrant and clear picture for news and talk shows, whereas the Sony X77L provides better upscaling and very good color accuracy, enhancing the overall clarity and color fidelity for such content. Considering SDR brightness, which is very important for daytime viewing, the LG UP7000 is fair, likely sufficient for most rooms, although in very bright rooms, it may not stand out as much, while the Sony X77L has good SDR brightness, making it more suitable for well-lit environments.
