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.

Milton Clark | September 2023
"For an entry-level model, Sony’s X77L is a decent 4K TV. It’s color reproduction, along with crisp and clean picture images revealed plenty of detail and clarity thanks in part to Sony’s excellent video processing."
