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.
When it comes to blacks and contrast, we must be honest – this is the area where the differences between QD-OLED and WOLED panels are virtually non-existent under typical cinematic conditions. We confirm with full responsibility: the Samsung S85F equipped with a WOLED panel achieves amazing and unparalleled results in this respect. Regardless of the scene being watched – whether it's a dynamic action movie or a dark thriller – we receive infinite contrast and perfect black that we expect from any OLED television. These are results that can impress even the most discerning cinephiles. It is worth emphasizing that such deep, absolute black can only be offered by televisions with organic panels. In cinematic conditions, as we see in our measurements, the level of black luminance is zero. So, if you dream of a screen that can "switch off" the light in a scene just as effectively as an independent cinema in a dark room, we are pleased to state that the S85F, also in the WOLED variant, is one of those televisions.
