The LG A1 OLED offers superior contrast and black uniformity, which makes it outstanding for watching movies and enjoying content in dark rooms. Its OLED technology also gives it wide viewing angles, beneficial for groups. However, it is less ideal for very bright rooms due to its moderate brightness levels. On the other hand, the Sony X90J LCD performs well in bright rooms and has higher brightness than the LG A1, making it suitable for daytime viewing. It also has a better response time and is more suited for gaming due to its lower input lag and higher refresh rate. However, its contrast and black uniformity are not as good as the LG A1's, affecting dark room performance. Choose the LG A1 if you prefer top-notch picture quality for movies in darker settings. Opt for the Sony X90J if you need a TV that's better for gaming and bright room use. Give Feedback

The LG A1 (OLED) is very good for movies & TV, while the Sony X90J (LCD) is good.
The LG A1's OLED display ensures perfect blacks due to its ability to turn off individual pixels, offering exceptional contrast and black uniformity which is crucial for a movie cinema experience. Conversely, the Sony X90J, while having lower contrast due to its LCD technology, excels in color accuracy and motion processing, making it a strong option for movies and TV, but with limited viewing angles and less ideal black uniformity compared to the LG A1.

The LG A1 (OLED) is very good for sports, while the Sony X90J (LCD) is good.
The LG A1 OLED has excellent response time and wide viewing angles, making it particularly good for watching sports as fast-moving images are crisp and can be seen from various positions around the room. In contrast, the Sony X90J LCD is good for sports due to its proficient motion processing and reflections handling, but it may not provide the same level of performance in response time or viewing angles as the OLED.

The Sony X90J (LCD) and LG A1 (OLED) are both very good for news, talk, & other TV, though the Sony X90J (LCD) is somewhat better.
The LG A1 excels in upscaling and has perfect contrast due to its OLED panel, making it suitable for news and talk shows where detail and clear text are important but its SDR brightness is only fair, which can be a drawback in well-lit rooms. The Sony X90J, while still providing strong upscaling and good local dimming for contrast, offers very good SDR brightness which makes it a better fit for viewing in bright rooms.

The Sony X90J (LCD) and LG A1 (OLED) are both very good for cartoons & animation.
The LG A1 excels with its OLED screen, offering outstanding colors straight out of the box along with a wider color gamut, which makes it great for watching cartoons and animation with vibrant and true-to-life hues. On the other hand, the Sony X90J, while it has good color accuracy out of the box and a decent color gamut, doesn't match the A1's performance in these areas, yet its LCD screen with full-array local dimming could offer better brightness in well-lit rooms, which is beneficial for daytime viewing.
