If you prefer a TV that offers excellent performance across a wide range of content, including movies, sports, and gaming, and particularly excels in dark room viewing due to its unparalleled black levels, the Samsung S90C (OLED) is a great choice. However, it has a lower brightness compared to the LCD model, so it might not be as suitable for very bright rooms. On the other hand, the Samsung QN90B (LCD) is very bright and performs well in bright rooms. It also has good overall picture quality and is quite versatile, but it may not offer the same level of dark room performance due to lesser black uniformity. Both TVs have a premium price and are similarly priced, so your choice should be based on the viewing environment and what content you prioritize. If you need a brighter screen for daylight viewing, go for the QN90B; if you value top-notch picture quality and gaming performance, the S90C is the superior option. Give Feedback

"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."
