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.
Well then, let’s get to the point, which is how the Haier K85F handles black levels and contrast. The key information is that the television uses a VA panel, which has a significant impact on the image quality in dark scenes. It is precisely because of this that the contrast is really solid – our measurements showed values around 5000:1, which is much better than that of popular IPS panels.
However, one must remember that we are talking about equipment from the lower price range. Therefore, one cannot expect any advanced technologies, such as local dimming. The backlighting works across the entire surface of the screen all the time. How did this look during viewing? We took the film “Oblivion” with its cosmic landscapes for a test, and also checked classic black bars in other productions. The effect was quite decent. The black had good depth, but it was not perfectly pitch black – a subtle, navy blue glow could be seen, indicating that the panel's backlighting was still active.
