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 Haier M90E is a fully-fledged Mini LED television that uses a VA panel. This combination of technology usually guarantees deep blacks and high contrast. In the tested 55-inch model, the backlighting system is based on 240 independent dimming zones, and their number increases proportionally in larger variants of this model. Laboratory measurements confirm the high hardware potential – in synthetic tests with active dimming, the contrast exceeded the value of 100,000:1.
However, the dry measurement data does not translate into an ideal image in real-world applications, which forced us to lower the score in this section. The bottleneck turned out to be the software controlling the zones. The algorithm operates too aggressively and replicates the errors we observed earlier in the more expensive M95E model. The problem becomes evident when bright objects move across a dark background on the screen. The system struggles to smoothly adjust the brightness of individual zones, resulting in unnatural flickering of certain parts of the image. Instead of smooth motion, we see an effect reminiscent of a flickering broken lantern, which was ruthlessly exposed by our test night scene from the film Sicario 2.
