If you prioritize picture quality for movies and series and plan to watch in a dark room, the LG C3 OLED will offer superior performance with deeper blacks and better contrast. It's also slightly better for gaming due to a faster response time. However, this TV isn't as bright as its counterpart, so it might not perform as well in a very bright room. The Samsung QN90B LCD is brighter, making it a better fit for bright room viewing. It also has excellent color volume and a faster input lag, which can be beneficial for gaming. However, its contrast isn't as high as the LG C3 OLED, which means it won't deliver quite as deep blacks in a dark room. Both TVs are similarly priced and support Dolby Vision and other HDR formats, providing a versatile viewing experience. Consider your main usage scenarios and room conditions to make the best choice for your needs. Give Feedback

USA Today

Michael Desjardin | October 2022
"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."
