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.
I must admit, when approaching a receiver in this price range, one instinctively crosses their fingers, hoping that at least the black won't be a gray blot. Meanwhile, the Haier Q80FUX, specifically the 55-inch model present in our editorial office, can very positively surprise in this regard. Its secret lies in using a VA panel, which by nature has an inclination for generating high contrast. And these are not empty promises. During screenings, in most film shots, the contrast consistently reported levels from 5000:1, often reaching as high as 8000:1. These are really strong results, considering the fact that this television does not possess any, even minimal, form of local dimming. Translating this into couch experiences: given its price realities, the Q80FUX offers simply solid blacks. Of course, it's not that perfectly velvety depth that makes the screen disappear into darkness. When we conduct a screening in conditions of complete isolation from light, we will notice that in the darkest parts of the image, the black reveals its budget origins, slightly shifting towards a bluish tint. However, this is a defect easy to mask – just a little light from a lamp in the corner of the room is enough for this nuance to become invisible, and the image to regain a satisfying depth.
