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.
Alright, but let's get to the meat of it, that is, how the Haier K85F handles black and contrast. The key information is that the television uses a VA panel, which is crucial for image quality in dark scenes. Thanks to this, the contrast is really solid – our measurements indicated values around 5000:1, which is much better than popular IPS panels.
However, it is important to remember that we're discussing budget equipment. So, we shouldn't expect any advanced technologies like local dimming. The backlighting operates across the entire screen surface at all times. How did it look during viewing? We took the film "Oblivion" with its cosmic landscapes for a test, and we also checked classic black bars in other productions. The effect was quite decent. The black had good depth, but it wasn't perfectly inky – a slight blue glow could be noticed, indicating that the panel's backlighting was still active.
