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.
The unit we tested, the Hisense U8Q in 65 inches, is equipped with a VA panel that offers high native contrast on its own. However, this is not the biggest strength of this model—the key lies in the Mini LED backlighting. With the use of thousands of dimming zones and a well-tuned light management algorithm, the contrast in the U8Q can be described as excellent, especially for a TV of this technology.
The best results reach around a million to one—a result that is impressive and places the U8Q among the top Mini LED TVs. Yes, there are certain issues and even drops in contrast, but they are not as dramatic as with many other models in this class that we have tested on our portal. It's also worth noting that like every Mini LED TV, the U8Q is not completely free from typical imperfections—sometimes the picture can be dimmed too much, or there may be slight blooming effects with a halo. However, this does not change the overall impression: the contrast in the Hisense U8Q is stunning and is one of the greatest assets of this model.
