When choosing between the LG B1 OLED and the Samsung QN90A LCD, consider the following tradeoffs: The LG B1 OLED provides deeper blacks and better viewing angles, making it excellent for movies and general TV in darker rooms. However, it may not be as bright as the Samsung QN90A, meaning it could be less suitable for very bright rooms. On the other hand, the Samsung QN90A boasts a brighter screen and is a strong performer in well-lit environments. This model is also slightly less expensive and can offer better value if you're looking to save some money. However, its black levels and viewing angles may not match those of the LG B1 OLED.

The Samsung QN90A (LCD) is best in class for bright room, while the LG B1 (OLED) is good.
The Samsung QN90A performs better in bright rooms mainly due to its higher SDR and HDR brightness capabilities, enhancing visibility even when there's a lot of ambient light, while both TVs handle reflections well. Although the LG B1 offers excellent contrast and color quality thanks to its OLED panel, this does not always compensate for its lower brightness compared to the high brightness levels of the Samsung QN90A's LCD panel.
