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 model PUS7000 tested by us in the size of 55 inches has been equipped with a VA panel. This is of great importance for the quality of black, as in such budget constructions we will not find local dimming systems that could assist the screen in dark scenes. All the work thus rests on the panel itself, which, thanks to its characteristics, offers decent contrast at the level of 6000:1. In practice, this translates to significantly better experiences during evening viewing than in the case of competing televisions with IPS panels. The black here is better separated from bright elements, which means that dark parts of the image do not appear washed out, and details in the shadows remain visible. It is worth adding, however, that with the lights completely off, the black may slightly take on shades of navy blue and will not be as perfectly "pitch black" as in more expensive models. To mitigate this effect and improve the perception of depth, it is advisable to consider watching the television with light, additional lighting in the room. Usually, this issue was somewhat resolved by the well-known Ambilight system from Philips televisions, which optically increases contrast through a glow on the wall. Unfortunately, in the PUS7000 model, the manufacturer decided to look for savings, so we will not find this backlighting system here, which is standard in higher series, such as the PUS8000.
