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.
The model PUS7000 we tested, measuring 55 inches, is equipped with a VA panel. This is crucial for black quality, as in such budget constructions, we won't find local dimming systems that could assist the screen in dark scenes. Therefore, all the work relies on the panel itself, which, thanks to its characteristics, offers decent contrast at a level of 6000:1. In practice, this translates to significantly better experiences during evening viewings compared to competing TVs with IPS panels. The blacks here are better separated from bright elements, so dark parts of the image don’t appear washed out, and details in the shadows remain visible. However, it’s worth noting that with completely turned off lights, the black may slightly lean towards shades of navy blue and won't be as perfectly “pitch-black” as in more expensive models. To mitigate this effect and improve the perception of depth, it’s advisable to watch the TV with some light, additional illumination in the room. Usually, this problem was somewhat resolved by the well-known Ambilight system in Philips TVs, which optically increases contrast through the glow on the wall. Unfortunately, in the PUS7000 model, the manufacturer opted to seek savings, which is why we won’t find this lighting system here, which is standard in higher series like PUS8000.
