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.
Samsung Q8F uses a VA LCD panel, which immediately puts it in a good position regarding contrast. By nature, such panels offer deeper blacks than IPS panels, and you can actually see this effect here. On test patterns, the contrast ranged from about 4000:1 to even 6000:1, which practically results in a surprisingly engaging image, especially in a slightly dimmed living room. Of course, this is not the level of LCD screens with local dimming, let alone OLED — sometimes the blacks can verge on a shade of navy, and the overall image can appear flat. However, Samsung employs a simple trick: so-called global dimming, which dims the entire screen when there are many dark sections. The effect can be impressive, but it comes at the cost of losing some details, which may not appeal to everyone. Nevertheless, the Q8F still performs significantly better than televisions with IPS panels, offering solid contrast and blacks that can immerse you in the cinematic atmosphere.
