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 (instead of at the edges), which gives a solid advantage 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 very impressive, but as it turned out, sufficient to achieve quite decent results.
In tests based on scenes from films such as Oblivion or 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 large number of bright details on a dark background), a halo effect appeared. This is where the limitation of the number of zones comes into play – bright elements could bleed around, and some details in dark areas became less visible. In one scene with a helicopter (The Meg), we even noticed slight brightness flickering, as if the television was trying its best to maintain visibility of the details at the expense of black depth.
However, these are not issues exclusive to this model – the halo effect or contrast drops in very complex scenes are something that most Mini LED televisions struggle with, even the more expensive ones. In its class, the QN80F still performs positively and offers noticeably better contrast than the QN70F model with edge lighting. For most users, this will be a level more than sufficient – although not perfect.
Philips MLED920 in the 55-inch version that we had the opportunity to test uses a high-contrast VA panel. The panel itself is one thing, but the real standout feature of this model is the mini-LED backlighting. This largely determines how black and contrast look – and it must be said that Philips has taken a big step forward compared to the models from 2024, where the local dimming algorithms performed just average. In this new version, it is significantly better, and the contrast presented by the MLED920 can truly surprise in a positive way. At times, it even approaches the level known from the best LCD TVs on the market – blacks can be deep, the image gains a three-dimensional quality, and viewing experiences in a dark room leave a great impression. Of course, as with any mini-LED TV, this is not an image completely free of compromises. With a large number of small elements on the screen, the local dimming algorithms can sometimes get confused – at times dimming details more than we would like and other times brightening the background, resulting in slight, light blue halos around objects (the so-called halo effect). Despite these imperfections, we must emphasize that black and contrast are truly strengths of the Philips MLED920 and definitely one of the reasons to consider it in the mid-range segment.
