If you primarily watch movies in darker environments, the LG B3 OLED may serve you better due to its superior contrast and perfect blacks, offering an immersive viewing experience. However, if your TV room is very bright or receives a lot of sunlight, the Samsung QN90A LCD, with its miniLED backlight and excellent brightness, will maintain a clearer picture in these conditions. For gaming, both are well-suited with features like 4K at 120Hz support, but the LG has a slight edge in motion handling. When it comes to durability and potential for burn-in, the Samsung QN90A may be the safer bet, as OLED TVs can be susceptible to burn-in with static images over time, whereas LCDs are not.

The LG B3 (OLED) is excellent for movies & TV, while the Samsung QN90A (LCD) is very good.
The LG B3 OLED offers perfect contrast and black uniformity, which are crucial for a deep, immersive movie-watching experience in dark rooms, and its wide viewing angles ensure a consistent picture when viewed from the side.
