If you care deeply about picture quality and want the deepest blacks and vibrant colors for a home theater experience, the LG B3 OLED TV would be a great choice. OLED's perfect black levels make it especially good for watching movies in dark rooms. On the other hand, if you tend to watch TV in bright environments, the Sony X90J LCD TV with its better brightness might serve you well, reducing glare and maintaining picture quality even in well-lit conditions. Keep in mind, however, that while both TVs are good for gaming, the OLED has a slight edge due to its faster response times, which can enhance the gaming experience. Give Feedback

The LG B3 (OLED) is excellent for movies & TV, while the Sony X90J (LCD) is good.
The LG B3 OLED displays exceptional contrast, perfect black uniformity, and wide viewing angles, which is ideal for movie scenes with deep blacks and shadow details, while the Sony X90J LCD offers good contrast and decent black uniformity but may exhibit some inconsistencies in black levels, particularly when viewed from an angle.
