When choosing between the LG A1 and LG B1, consider the following: The LG B1 offers better overall performance, particularly for gaming and sports, due to its higher refresh rate which can make fast action appear smoother. It also has better processing for upscaling lower-resolution content and slightly better sound quality. However, the LG A1 is significantly cheaper and still offers excellent picture quality for general TV watching and movies, particularly in darker environments due to its OLED display. If budget is a significant concern and you primarily watch movies or TV shows in a dark setting, the A1 could be a sensible choice. But if you're into gaming or watch a lot of sports, and if you can stretch your budget, the B1 would provide a more fluid viewing experience. Both struggle in bright rooms, so they're best suited to environments where you can control the lighting. Give Feedback
