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.
Haier M90E is a fully-fledged Mini LED television using a VA panel. This technological combination typically ensures deep blacks and high contrast. In the tested 55-inch model, the backlight system is based on 240 independent dimming zones, and their number increases proportionally in the larger variants of this model. Laboratory measurements confirm high hardware potential – in synthetic tests with active dimming, the contrast exceeded 100,000:1.
However, the dry measurement data do not translate into an ideal image in real-world applications, which forced us to lower the rating 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 model M95E. The problem becomes apparent 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, as ruthlessly exposed by our test night scene from the film Sicario 2.
