Hisense U7NQ is a television that uses a VA panel, crucial for achieving good contrast and appropriate black depth. This technology translates into vivid image quality when watching content in a dark room, where blacks acquire proper saturation and resemble deep tar rather than washed-out ash. Moreover, the TV features Mini LED backlighting, which in the tested 65-inch variant offers an impressive number of 713 local dimming zones. Naturally, smaller sizes will have fewer zones, while larger ones will have more, positively affecting overall contrast.
Under very favourable conditions, the TV achieves a contrast ratio of around 40,000:1. The local dimming technology performs excellently at managing bright and dark parts of the image, making the TV superbly render details in complex scenes. Despite the large number of zones, there may be issues with contrast in particularly demanding scenes, where small bright elements appear against a dark background. Sometimes the TV may dim these elements too much, causing a loss of brightness, and other times it excessively brightens them, leading to a halo effect—glows of light surrounding objects. This effect can be noticeable, for example, in a scene from the movie Sicario 2, where bright glows around the subtitles can be bothersome.
Nevertheless, the use of Mini LED technology with local dimming makes the overall image quality significantly better than in televisions without this technology. The effect is particularly noticeable when watching movies in a dark room—the blacks are deeper, and the contrast is more pronounced, allowing a full appreciation of details hidden in dark shots.
Let's get to the point, which is what is most important in the Mini LED panel: black levels and contrast. The Xiaomi S Pro 2026 is built on a VA matrix, which right from the start promises deep blacks. Let's add to that Mini LED backlighting with a very large number of local dimming zones. In the 65-inch variant we tested, we counted as many as 532 of them. That's a solid number that should provide precise control over the backlighting. It should be noted that this number is proportional to the size—choosing the smaller 55-inch variant will result in correspondingly fewer zones, while larger models will have more.
So, how does the black level perform on the S Pro 2026? The answer is complex.
Generally, it's really not bad, and we see a clear improvement compared to the problematic model from 2025. As you can see in our measurement charts, the results are occasionally spectacular. In most of the film scenes we measured in SDR (standard dynamic range), the contrast could be confidently described as very good and even comparable to constructions three times more expensive. Well, it could be... and this brings us to the paradox of this model. The problem lies in how the TV manages zones in scenarios other than SDR. As soon as we feed the TV a higher quality signal, such as an HDR series or Dolby Vision from streaming platforms (Netflix, HBO Max, or Disney+), something strange happens. We have an overwhelming impression that the TV suddenly... forgets that it was equipped with local dimming zones at all. As shown in our video below, the black in such scenes resembles more shades of dark gray or navy blue. On top of that, there's a slight flickering of the entire screen. This is the level one would expect from TVs completely devoid of a local dimming system. It seems that Xiaomi decided to fix one, but crucial flaw of last year's 2025 model over the year. And they succeeded – we no longer have the annoying "zone disco," and the picture is stable. It's just a pity that when consuming top-quality content (HDR), the whole advanced system becomes completely useless.
