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.
TCL P8K is an example of a television that shows that even in the lower range, you can still find solid contrast. The VA panel does a really good job here – a measurement around 6000:1 may not sound impressive, but in real scenes, it creates an effect that is simply pleasing to the eye. In the darkness of the forest in “The Revenant” or in the futuristic scenes of “Oblivion,” you can see depth and light separation that’s hard to expect from equipment at this price. The P8K can render darkness without the feeling that everything is drowning in grey. The Direct LED backlighting also works in its favour. Of course, there is no local dimming here, but the system can dim the whole screen when the scene requires it or slightly brighten it to bring out details in the bright areas. It's a somewhat analogue approach to contrast – simple but effective. This was well demonstrated on the test pattern from the legendary Pioneer Kuro: the television prioritised bright points, while the background lost some depth, yet it still retained a decent appearance. Of course, there is no perfectly jet-black here. In a dark room, you can see that the black leans towards navy, but despite that, the overall presentation is just good. In normal home conditions, the contrast is more than enough to feel the cinematic atmosphere.
