The Samsung QN90B is an LCD TV that generally costs less compared to the Sony A90J which is an OLED TV. If you watch a lot of movies or would like to enjoy deeper blacks and better viewing angles, the Sony A90J excels in dark room performance and has overall superior picture quality. However, if you are in a bright room, the Samsung QN90B has a higher bright room performance, which makes it a better fit for well-lit environments. For gaming, the Sony A90J also has a slight edge with quicker response times and slightly better motion processing, making it ideal for fast-paced games. Both TVs have great speakers and a similar range of smart features, but the Sony A90J tends to deliver slightly better sound quality. Give Feedback

The Sony A90J (OLED) is excellent for movies & TV, while the Samsung QN90B (LCD) is very good.
The Sony A90J offers unrivaled contrast, perfect black uniformity, and better viewing angles thanks to its OLED technology, making it exceptional for movies with deep black scenes and wide seating arrangements. The Samsung QN90B, though, with its strong local dimming and high contrast on an LCD panel, also excels in presenting vivid cinematic content, but it might not match the Sony's absolute blacks and consistent color performance at various angles.

The Sony A90J (OLED) is excellent for sports, while the Samsung QN90B (LCD) is good.
The Sony A90J OLED TV offers excellent motion processing and response time, which makes fast-paced sports less blurry and more responsive than the Samsung QN90B LCD TV. While both handle reflections well, the OLED's wider viewing angles are beneficial for group watching, though the Samsung's screen may perform slightly better in terms of gray uniformity, which can affect the viewing experience less significantly than the other factors.

The Samsung QN90B (LCD) is best in class for bright room, while the Sony A90J (OLED) is good.
The Samsung QN90B provides excellent SDR and HDR brightness and handles reflections superbly, ideal for a bright room; whereas, the Sony A90J also manages reflections excellently but offers less brightness for SDR and HDR content, meaning it might not cut through ambient light as effectively as the Samsung model. The Samsung's enhanced brightness comes at the expense of perfect blacks due to its LCD display, while the Sony offers superior contrast with its OLED technology, alongside a better color gamut and volume, enhancing the viewing experience where brightness is less of a concern.

Although they have very similar scores, PerfectRec considers Samsung QN90B (LCD) to be excellent for news, talk, & other TV, while the Sony A90J (OLED) is very good.
The Samsung QN90B excels in SDR brightness and displays vivid colors straight out of the box, making it well-suited for watching news and TV shows in well-lit rooms.

"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."

"In every meaningful department – motion control, contrast, edge definition, detail levels, you name it the A90J puts in a memorably accomplished shift. In fact, the Sony proves outstanding at handling on-screen motion of any and every kind. By the standards of television audio systems, the A90J is a notably punchy and genuinely dynamic performer."
