QN80F is a representative of the Neo QLED series, which means it's a television with Mini LED backlighting. Unlike its cheaper cousin, the QN70F model, here the diodes are placed directly behind the panel (rather than at the edges), which gives a solid advantage in contrast control right from the start. In the 65-inch variant we tested, we counted 88 local 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 movies like Oblivion and 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 lot of bright details on a dark background), a halo effect appeared. This is where the limitation of the number of zones shows – bright elements could bleed into each other, and some details in dark areas lost sharpness and contrast. In one of the helicopter scenes (The Meg), we even noticed a slight flicker in brightness, as if the television was trying its best to maintain visibility of details at the expense of black depth.
However, these are not problems exclusive to this model – the halo effect or contrast drops in very complex scenes are something most Mini LED televisions struggle with, even the more expensive ones. In its class, the QN80F still performs positively and offers clearly better contrast than the QN70F model with edge lighting. For most users, this will be a level more than sufficient – though not ideal.
The NanoCell series, including the NANO81 model we tested, is based on an IPS panel. For anyone who has even a little knowledge about screens, this means one thing: significant problems with black levels and contrast. Our measurements are ruthless here. A result of 800:1 is, quite frankly, a tragic score. In practice, this means that what should appear on the screen as deep black looks like a dark gray blot at night. Watching dark films or series in a completely dark room will simply be torturous – the image will lose all its depth and will appear flat. If you decide to go with this model, we have one key piece of advice for you: don't watch it in complete darkness. To salvage the situation somewhat, it's best to leave a soft light on in the room, and the ideal solution would be to install an LED strip behind the television. Such wall lighting will trick your eye (this is known as simultaneous contrast) and make that grayness on the screen seem a bit darker. Nonetheless, the start of the test in terms of cinematic experiences looks bleak.
