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
