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.
The Philips MLED920 in the 55-inch version that we had the opportunity to test features a VA panel with high contrast. The panel itself is one thing, but the true distinguishing feature of this model is the mini-LED backlighting. This largely determines how black levels and contrast appear – and it must be said that Philips has made a significant leap forward compared to the models from 2024, where the local dimming algorithms were simply mediocre. The new version is much improved, and the contrast presented by the MLED920 can truly surprise positively. At times, it resembles the level known from the best LCD televisions on the market – blacks can be deep, the picture gains a sense of three-dimensionality, and watching films in a dark room makes a great impression. Of course, as with any mini-LED television, this is not a picture completely free of compromises. With a large amount of fine details on the screen, local dimming algorithms can sometimes get confused – at times dimming details more than we would like, and at other times brightening the background, resulting in slight, light blue halos around objects (the so-called halo effect). Despite these imperfections, we must emphasise that black levels and contrast are truly a strong point of the Philips MLED920 and definitely one of the reasons why it should be considered in the mid-range category.
