QN80F is a representative of the Neo QLED series, meaning it is a television with Mini LED backlighting. Unlike its cheaper cousin, the QN70F model, the diodes here are placed directly behind the panel (rather than at the edges), which gives it a solid advantage right from the start when it comes to contrast control. In the 65-inch variant we tested, we counted 88 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 films such as Oblivion and The Meg, the QN80F performed well – blacks were deep, and the overall image consistency was visually appealing. However, in more demanding moments (e.g., scenes with a large number of bright details on a dark background), a halo effect appeared. This is where the limitation of the number of zones becomes evident – bright elements could bleed into one another, and some details in the dark areas lost visibility. In one scene featuring a helicopter (The Meg), we even noticed slight brightness flickering, as if the television was trying its best to maintain detail visibility at the expense of black depth.
However, these issues are not exclusive to this model – halo effects or drops in contrast during very complex scenes are challenges faced by most Mini LED televisions, even the more expensive ones. In its class, the QN80F performs positively and offers significantly better contrast than the QN70F model with edge backlighting. For most users, this will be a level more than sufficient – although not perfect.
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 already promises deep blacks from the start. Adding to that is the 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. This is a solid number that should provide precise control over the backlighting. It should be noted that this number is proportional to the size – by choosing the smaller 55-inch variant, there will be correspondingly fewer zones, and in larger models, more.
So, how does the black level perform on the S Pro 2026? The answer is complex.
Overall, it is really quite good, and we see a clear improvement compared to the problematic model from 2025. As you can see from our measurement charts, the results are sometimes 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 designs three times as expensive. Well, it could be... and here we come to the paradox of this model. The issue is how the television manages the zones in scenarios other than SDR. As soon as we feed the television 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 the undeniable impression that the television suddenly... forgets that it has been equipped with local dimming zones at all. As can be seen in our video below, the black levels in such scenes resemble more shades of dark grey or navy blue. Additionally, there is a subtle flickering of the entire screen. This is a level we would expect from televisions entirely devoid of a local dimming system. It seems that Xiaomi decided to fix one, but key, flaw of last year's 2025 model over the course of a year. And they succeeded – we no longer have the annoying "zone disco", the image is stable. It's just a shame that when consuming content of the highest quality (HDR), this entire advanced system becomes completely useless.
