If you prioritize exceptional picture quality in darker environments and cinematic experiences, the Sony A90K with its OLED screen might be the better option; it offers deeper blacks and is best suited for watching movies and playing games. However, it may not perform as well in bright rooms. On the other hand, the Samsung QN90B is less expensive and boasts an LCD screen with miniLED technology, which makes it excellent for bright room viewing and delivers good picture quality for sports and regular TV shows. It also has better sound with a more powerful speaker system. If budget is a concern and you often watch TV in well-lit rooms, the QN90B could satisfy your needs more economically. Give Feedback

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."
