The QN70F is equipped with a VA panel that offers a high native contrast – this is already a good starting point for black levels, especially during evening viewing. However, its capabilities do not theoretically end there. The television is branded as Neo QLED, which indicates the presence of Mini LED technology and a local dimming system. And indeed – the QN70F has this function. The problem is that we are not talking about classic local dimming with LEDs positioned directly behind the panel. Instead, edge lighting has been implemented with an overall dimming mechanism known as global dimming. The effect of this is that instead of selective brightness control in individual zones, the entire screen is slightly dimmed when a dark scene appears. In practice, this means that the contrast is average compared to Mini LED models that offer true local dimming. The black levels are not bad – thanks to the VA panel itself – but one cannot speak of precise light control like that provided by advanced systems with multiple zones. This raises the question: is the QN70F series really a Mini LED television, or just a marketing variation on the Q70 series? Looking at the technical aspects – it is hard to consider this model a full-fledged representative of this technology. But in everyday use, the black levels appear decent and for many people may be fully satisfactory.
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.
