QN80F is a representative of the Neo QLED series, which means it's a television with Mini LED backlighting. Unlike its cheaper cousin, the QN70F model, here the diodes are placed directly behind the panel (rather than at the edges), which gives a solid advantage in contrast control right from the start. In the 65-inch variant we tested, we counted 88 local dimming zones – a result that may not be particularly impressive, but as it turned out, sufficient to achieve quite decent results.
In tests based on scenes from movies like Oblivion and The Meg, the QN80F performed well – blacks were deep, and the overall image consistency was eye-catching. However, in more demanding moments (e.g., scenes with a lot of bright details on a dark background), a halo effect appeared. This is where the limitation of the number of zones shows – bright elements could bleed into each other, and some details in dark areas lost sharpness and contrast. In one of the helicopter scenes (The Meg), we even noticed a slight flicker in brightness, as if the television was trying its best to maintain visibility of details at the expense of black depth.
However, these are not problems exclusive to this model – the halo effect or contrast drops in very complex scenes are something most Mini LED televisions struggle with, even the more expensive ones. In its class, the QN80F still performs positively and offers clearly better contrast than the QN70F model with edge lighting. For most users, this will be a level more than sufficient – though not ideal.
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.
