Both are premium, similarly priced models with excellent performance in bright rooms and strong contrast features.

The Samsung QN90C (LCD) and Samsung QN90A (LCD) are both good for sports.
The Samsung QN90A boasts a very good response time and reflections handling, making it well-suited for sports in bright rooms, although its gray uniformity is somewhat lower, which might be noticeable in panning shots. The QN90C also performs well with sports, with excellent motion processing and good response time, but like the QN90A, it has a similar viewing angle which means colors can fade when viewed from the side.

The Samsung QN90C (LCD) and Samsung QN90A (LCD) are both very good for cartoons & animation.
The Samsung QN90A stands out for watching cartoons and animation due to its superior 'Colors Out of the Box', meaning you'll get vibrant and accurate colors without needing to adjust settings. The Samsung QN90C, while also delivering good performance with colors straight out of the box, offers a slightly better 'Color Volume', ensuring colors maintain their richness at a wide range of brightness levels, but it doesn't quite match the QN90A's initial color accuracy.

Although they have very similar scores, PerfectRec considers Samsung QN90C (LCD) to be excellent for news, talk, & other TV, while the Samsung QN90A (LCD) is very good.
The Samsung QN90A and QN90C are very good for watching news, talk shows, and TV programs because they both excel at maintaining image clarity when upscaling low-resolution content and have impressive screen brightness for SDR content, ensuring that the picture remains clear and vibrant even without HDR. While both models have high-quality colors straight out of the box, the QN90C edges ahead with slightly better contrast and local dimming, enhancing the viewing experience with deeper blacks and more pronounced highlights.

The Samsung QN90C (LCD) and Samsung QN90A (LCD) are both best in class for bright room.
The Samsung QN90C outshines the QN90A in a bright room mainly because its SDR brightness is higher, which means it can better combat glare during daylight, and its ability to handle reflections is equally excellent on both TVs. While the QN90A has a slight edge in HDR brightness, ensuring rich visuals in high dynamic range content, this difference is not substantial enough to overshadow the QN90C's superior bright-room performance; both TVs have similarly good color volume and color gamut, important for vivid and accurate colors, but less critical than brightness and reflectivity in bright environments.
