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.
TCL P8K is an example of a television that shows that even in the lower tier, one can still encounter solid contrast. The VA panel does a really good job here – a measurement around 6000:1 may not sound spectacular, but in actual scenes it produces an effect that simply delights the eye. In the darkness of the forest in "The Revenant" or in the futuristic shots of "Oblivion", depth and light separation are visible, which is difficult 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, we do not have any local dimming here, but the system can dim the entire screen when the scene requires it or slightly brighten it to bring out details in bright areas. This is somewhat of an analogue approach to contrast – simple but effective. On the test pattern from the legendary Pioneer Kuro, it was well evident: the television prioritised bright points while the background lost some depth; however, it still maintained a decent appearance. Of course, there is no perfectly inky black here. In a dark room, it is noticeable that the black leans towards blue, but despite this, the overall presentation is simply good. Under normal home conditions, the contrast is entirely sufficient to feel the cinematic atmosphere.
