The Samsung QN90B is an LCD TV that costs a premium price and offers very good overall picture quality with particularly high brightness, making it suitable for bright rooms. Its gaming performance is excellent, sound quality is solid, and it includes great speakers. On the other hand, while it supports HDR10+, it does not support Dolby Vision. The Sony A80K is an OLED TV, also at a premium price point. It generally provides better picture quality than the Samsung, especially in dark rooms due to its perfect black levels. It has incredible gaming scores and viewing angles, making it great for sports and group viewing. The color accuracy and motion processing are exceptional. However, this TV may not be as well-suited for very bright rooms because it's not as bright as the Samsung. It supports Dolby Vision but not HDR10+. If you often watch TV in a bright room or prioritize peak brightness, the Samsung QN90B would be a good choice. For those who value perfect blacks, wide viewing angles, and outstanding motion handling for sports and gaming, the Sony A80K is a better fit, as long as you can manage with lower brightness in well-lit environments.

The Sony A80K (OLED) is excellent for movies & TV, while the Samsung QN90B (LCD) is very good.
The Sony A80K's OLED display provides perfect blacks due to its per-pixel lighting, resulting in excellent contrast and superb black uniformity, which enhances movie watching in dark environments. On the other hand, the Samsung QN90B, with its mini LED LCD screen, offers very good contrast and local dimming which helps darker scenes but may not reach the absolute blacks of the Sony A80K, which could be more visible in a dark room.

The Sony A80K (OLED) is excellent for sports, while the Samsung QN90B (LCD) is good.
The Sony A80K's OLED panel provides excellent motion processing and wide viewing angles, which is ideal for fast-paced sports content and group viewing. The Samsung QN90B, although very good in handling reflections and with fast response times essential for sports, doesn't match the Sony's superior motion handling or as wide viewing angles, which can make a difference during dynamic sports games.

The Samsung QN90B provides excellent SDR and HDR brightness and handles reflections very well, which is ideal for bright rooms. In comparison, the Sony A80K offers good SDR brightness and very good reflection handling, but its HDR brightness is only fair, meaning it might not stand out as much in very bright environments.

"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."

"It’s a high-end TV through and through something that becomes clear the moment you glance at its stunning picture. The A80K’s surgically precise contrast control is likely the first thing you’ll notice about its picture ... every piece of content looks better when this amount of precision is available. Color accuracy is another strong suit; the A80K features fantastic out-of-the-box color accuracy in the Custom picture mode."
