The Samsung QN90A is a premium price option and is typically much more expensive than the Sony X85K. If you are looking for a TV with better overall picture quality, particularly in bright rooms, and superior gaming performance, the Samsung QN90A would be an excellent choice. It also has better sound quality with great built-in speakers.
On the other hand, the Sony X85K is a midrange price option, which is typically much less expensive, and still offers good gaming performance and picture quality for sports content. However, it may not perform as well in dark rooms and its sound quality is not as impressive as the Samsung QN90A.
Keep in mind that both TVs have a 120 Hz LCD screen and support HDR formats, but the Samsung QN90A uses miniLED technology which contributes to its higher price. The choice between the two will depend on whether you prioritize superior performance and features or are looking for a more cost-effective option with satisfactory performance. Give Feedback

The Samsung QN90A (LCD) is very good for gaming, while the Sony X85K (LCD) is good.
The Samsung QN90A is favored for gaming due to its superior response time and lower input lag, which translates to a smoother picture with less motion blur and quicker on-screen reactions to player inputs. On the other hand, the Sony X85K performs well, but doesn’t match the Samsung’s responsiveness and speed, making it less optimal for high-paced gaming situations.

The Samsung QN90A (LCD) and Sony X85K (LCD) are both very good for news, talk, & other TV, though the Samsung QN90A (LCD) is somewhat better.
The Samsung QN90A has excellent SDR brightness, which is crucial for viewing in well-lit rooms, and it performs incredibly well in upscaling lower resolution content, making it ideal for watching news and talk shows that aren't always broadcast in high definition. The Sony X85K, while slightly better at upscaling, also provides a vibrant picture with its excellent color accuracy right out of the box, and good SDR brightness, ensuring that news and TV programs are displayed clearly.

The Samsung QN90A (LCD) is best in class for bright room, while the Sony X85K (LCD) is good.
The Samsung QN90A outshines the Sony X85K in a bright room as it has superb SDR and HDR brightness and excellent handling of reflections. Sony's X85K, while still good in bright conditions, has lower SDR and HDR brightness and is not as effective at minimizing reflections.
The Sony X85K (LCD) and Samsung QN90A (LCD) are both good for sports.
The Samsung QN90A provides excellent motion processing and a high response time, making it well-suited for sports where these aspects ensure smooth playback and quick image transitions. In contrast, the Sony X85K has a perfect score in motion processing and also boasts a good response time, though it has a less effective reflection handling and narrower viewing angles compared to the Samsung QN90A, which might reduce the viewing experience from certain angles or in brightly-lit rooms.
