When deciding between the Samsung Q80B and QN90A, go for the Q80B if you're looking for a high-quality TV at a more approachable price point. It's strong in gaming and day-to-day TV programs but falls a bit short in dark room performance. In contrast, the QN90A excels in bright room settings thanks to better handling of reflections and a higher brightness level, which may justify its higher price tag. It also offers superior performance for movies and has a higher contrast ratio, making it a compelling option for movie enthusiasts and those wanting a more immersive viewing experience across all content types. Both TVs are similar in their gaming capabilities and support for the latest gaming features. Give Feedback

The Samsung QN90A (LCD) is very good for movies & TV, while the Samsung Q80B (LCD) is only fair.
The Samsung QN90A provides a more immersive movie and cinematic TV experience primarily due to its superior contrast, local dimming, and black uniformity, which are all very important for picture quality in darker scenes. The Q80B, while offering good performance, falls short in these areas compared to the QN90A, although it may have slightly better viewing angles due to its different panel technology.

The Samsung QN90A (LCD) is very good for cartoons & animation, while the Samsung Q80B (LCD) is good.
The Samsung QN90A is considered very good for watching cartoons and animation because it displays colors exceptionally well right out of the box and has a good color gamut, providing vibrant and accurate colors for animated content. The Samsung Q80B, while also good for animation, has colors that aren't as finely tuned initially and a similar color gamut, meaning that it can still render a wide array of colors but may not pop as much as the QN90A.

The Samsung QN90A (LCD) is very good for news, talk, & other TV, while the Samsung Q80B (LCD) is good.
The Samsung Q80B is good for watching news, talk shows, and other TV programs due to its very good SDR brightness and ability to upscale lower resolution content well, alongside a satisfactory score for colors out of the box, which is significant for a natural image. However, the Samsung QN90A is very good for the same content as it offers excellent SDR brightness and superior upscaling, which enhances the clarity and detail of the broadcast, and has better local dimming and contrast that contribute to its very good color reproduction.

Tom's guide
Matthew Murray | February 2023
"For most people its picture, sound, and price make it a midrange TV worth considering. HDR brightness was generally exceptional. Its viewing angles are shockingly good, among the very best we’ve seen recently from any non-OLED TV. For gamers input lag isn’t too shabby."
