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 NanoCell series, including the model NANO81 we tested, is based on an IPS panel. For anyone who's somewhat familiar with screens, this means one thing: huge problems with blacks and contrast. Our measurements here are merciless. A result of 800:1 is, to put it bluntly, a tragic outcome. In practice, this means that what should appear as deep black on the screen looks like a dark grey blob at night. Watching dark films or series in a completely dark room will simply be torture – the image loses all its depth and appears flat. If you do decide to go for this model, we have one key piece of advice for you: don’t watch it in total darkness. To salvage the situation somewhat, it's best to leave a gentle light on in the room, and the ideal solution would be to install LED strips behind the television. Such wall lighting will trick your eye (this is known as simultaneous contrast) and make that grey on the screen seem a bit darker. Nevertheless, the beginning of the test regarding cinematic experiences is looking grim.
