The LG B3 OLED TV provides deeper blacks and better viewing angles compared to the Samsung QN90C LCD TV, which makes it ideal for movie watching in dark rooms. On the other hand, the Samsung QN90C, with its LCD panel, is better for bright rooms and has a higher brightness level, which is a plus for watching TV shows or sports during the day. If cost is a factor and you mostly watch movies, the LG B3 OLED may offer you a better value. However, if you prefer a TV that handles glare well and you don't mind spending more, the Samsung QN90C might suit you better. Both TVs support high frame rates for gaming and have similar connectivity options. Give Feedback

The Samsung QN90C (LCD) and LG B3 (OLED) are both very good for news, talk, & other TV, though the Samsung QN90C (LCD) is somewhat better.

The Samsung QN90C (LCD) is best in class for bright room, while the LG B3 (OLED) is good.
The Samsung QN90C, with its best-in-class SDR and HDR brightness levels and excellent reflection handling, is more suitable for bright rooms compared to the LG B3, despite the latter's perfect contrast which enhances viewing in various lighting conditions. The QN90C's superiority in bright rooms also stems from its greater ability to retain the vibrancy of colors (color volume) and range of colors shown (color gamut), both of which contribute to a more vivid and colorful picture in well-lit environments.
