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.
I must admit that approaching a TV in this price range, one instinctively crosses their fingers, hoping that at least the black won't be a grey blotch. Meanwhile, the Haier Q80FUX, specifically the 55-inch unit we have in our office, can pleasantly surprise in this regard. Its secret lies in the use of a VA panel, which tends to generate high contrast by nature. And these are not empty promises. During screenings, in the majority of film scenes, the contrast reported itself at levels ranging from 5000:1 with commendable regularity, often reaching as high as 8000:1. These are really strong results, considering the fact that this TV has no, not even minimal, form of local dimming. Translating this into couch-side experiences: for its price point, the Q80FUX offers solid black levels. Of course, it isn’t that perfectly velvety depth that makes the screen disappear into darkness. When we conduct a viewing in total light isolation, we can see that in the darkest parts of the image, the black betrays its budget origins, subtly shifting towards a bluish glow. However, this is a defect that is easy to mask – just a bit of light from a lamp in the corner of the room is enough for this nuance to become invisible, and the image regains a satisfying depth.
