The LG A2 is a high-end OLED TV, which means it offers excellent dark room performance, superior viewing angles, and top-notch picture quality for movies and cinematic content. On the other hand, the Samsung QN90B is an LCD TV with mini-LED technology that provides a very bright picture, making it superior for bright room viewing. If your viewing environment is often dark and you watch a lot of movies, and you're willing to spend more, the LG A2 would be a great choice. If you're looking for a more affordable TV that performs well in bright conditions and for gaming, the Samsung QN90B would be a better option. Give Feedback

The LG A2 (OLED) is very good for sports, while the Samsung QN90B (LCD) is good.
The LG A2, with its OLED screen, has excellent response time and wide viewing angles, making it better for fast-paced sports action, particularly in rooms where viewers are seated at different angles relative to the TV. Conversely, the Samsung QN90B handles reflections exceptionally well and also has very good motion processing, but its viewing angles are not as wide, making it more suitable for head-on viewing rather than from the sides.

"Movie fans will find a lot here to love, and the A2 series’ low prices compared with other OLED TVs will keep their wallets happy. Images had the deep blacks and detailed shadows typical of the best 4K TVs, while colors looked both fully saturated and clean. Also, the A2’s out-of-box picture performance in Filmmaker mode was mostly accurate, requiring only slight adjustments to optimize brightness, color, and contrast."

"The QN90B delivers one of the brightest pictures we’ve ever seen, showcasing HDR content better than just about every LCD/LED TV on the market. If all you’re planning on doing is watching cable TV, broadcast channels, and a fair share of streaming shows or movies, the QN90B is sure to impress. All four of the QN90B’s HDMI 2.1 ports support 4K gaming at 120fps a centerpiece feature of the Xbox Series X and PlayStation 5."
