If you're looking for a TV with deep blacks and excellent performance in dark rooms, the LG B2, an OLED TV, is less expensive and is a strong choice. However, its performance in bright rooms isn't as good as some alternatives. The Samsung QN90B, on the other hand, is an LCD TV that's more expensive, but it offers very good brightness, making it suitable for well-lit rooms. It also has better built-in speakers if that's important to you. However, it doesn't match the LG B2 in terms of perfect blacks due to its technology. Give Feedback

Tom's guide

Nick Pino | March 2023
"The LG B2 OLED pairs lush, saturated colors and perfect contrast with a 120Hz screen, HDMI 2.1 ports and a great smart TV platform. The LG B2 OLED is an ideal alternative to the LG C2 OLED for folks who want a taste of OLED life without the sticker price that usually comes with it. The LG B2 OLED does a lot right in terms of performance, color saturation is wonderful and contrast is second-to-none. Not only did color saturation and off-axis viewing impress me, harder to quantify specs like motion processing and upscaling really blew me away as well."

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."
