Power supply and consumption Information about the power supply and consumption, energy efficiency class, etc. 110V Approximate height of the display. If the manufacturer does not provide such information, the height is calculated from the diagonal and the aspect ratio. When we say ‘advanced local dimming zone solution’, we mean it. Remarkably, the QE50QN90A can simultaneously deliver different levels of light from no less than 448 separate LED zones. To give this more context, Sony’s 50-inch XBR-50X90J LCD TV uses just 24 local dimming zones. This clear definition between the darkest and brightest parts of the picture is again the sort of thing you’d only normally see on an OLED TV, and transforms how easy it is to become immersed in what you’re watching. Information of the number of pixels in a unit of length. With the decrease of the display size and the increase of its resolution, the pixel density increases.

The QN90A’s user interface is powered by Tizen, a Linux-based, open-source operating system. It’s among the better smart TV platforms out there and is responsive, intuitive and easy to navigate. The interface features a launcher bar along the bottom of the screen, along with a second layer that provides faster access to the various streaming services and applications on offer. But speaking of motion processing, it’s worth talking about the new Motion Xcelerator Turbo+ technology that’s used by the Neo Quantum Processor 4K. It’s slightly more judicious in the way it uses judder reduction, but stutter is still an issue because of the way the TV’s native 120Hz refresh rate. Basically, the TV can overprocess some images, giving films a soap opera effect or, worse, making some scenes that have a bit of a natural shaky cam effect look like something from the Blair Witch Project or Cloverfield – it’s non-stop shaking that can really be a turn off. The energy efficiency class/label provides general idea about the power consumption. There are different energy efficiency classes and each sets its own requirements regarding the power consumption. Some of the existent energy efficiency classes are A+++, A++, A+, A, B, C, D, E, F, G. Gamers will be glad to know the Samsung QN90A has one of the best lag times you’ll find. Our review unit measured lag time of 12.6 milliseconds with its auto low latency mode —a huge improvement over the Q80T’s 30.1 milliseconds. Usually we recommend sets with sets with a lag time below 20 milliseconds for the best gaming TVs, and the addition of gaming-focused features make the QN90A Neo QLED an excellent choice for gamers. Samsung QN90A Neo QLED TV review: Audio HDR stands for High Dynamic Range and refers to a technology that more accurately expresses visual detail in both very bright and very dark scenes.The storage humidity shows the lower and upper humidity limit, which ensures safe storage of the display. Storing it outside these limits might damage the display. And yet, it’s largely a delight to watch. With most content it’s brighter, punchier and more vibrant than its rivals, and without veering into obvious exaggeration. It’s fun, exciting and yet controlled in its delivery, and its motion-handling is really good, too. On top of that, it’s got superb gaming specs that are second only to those of the LG C2, and even then only by a tiny amount. Information about whether the stand can be dismounted. Usually, this is required for wall mounting. The only catch with the 50QN90A’s upscaling is that it can start to look too fizzy with very grainy sources. This slight harshness can be softened away by the noise reduction options, but this inevitably leads to softer, occasionally slightly processed-looking results. To reiterate this point, though, the fizzing problem only happens with unusually grainy sources. With relatively pristine HD images the 50QN90A’s upscaling is outstanding.

Just when Samsung found its stride with QLED, keeping up the capabilities of its OLED competitors, it innovated the heart of its product with an all-new panel —a panel that actually showcased improvements in our testing. It also reminded QLED alternatives it’s still the company to beat. Watching the "All-New Halloween Spooktacular” episode of WandaVision on Disney Plus, the set could show off how it handles motion and high-contrast scenes. As Wanda extends the reach of her Hex, the S.W.O.R.D. camp is turned into a traveling circus. Even as the agents try to escape the growing boundary, you can see their uniforms and equipment transform seamlessly (and hilariously) into clown garb and colorful tents. Except when a curious Vision reaches the Hex’s boundary, glowing in dark fields, there seems to be a bit of blooming, as well as occasional vignetting in the corners.One of the reasons the QN90A is a bit more unstable this year is because it’s a bit thinner. Compared to last year, Samsung shaved about half an inch from the depth from the TV which has meant making some compromises on sound quality and stability. That’s not a bad thing if you plan on connecting the TV to an external sound system – like one of Samsung’s Dolby Atmos soundbars – and wall-mounting the TV, but it’s all worth noting. The screen has an anti-glare layer that effectively reduces reflections from ambient light in the room, while the TV does a solid job at reducing the colour and contrast drop-off typically experienced by LCD panels when viewed at extreme angles. These talents make the 50QN90A a seriously compelling gaming display too, despite the set having to rein in some of its contrast and colour enhancement technologies to deliver its exceptionally low 9.2ms (at 60Hz) input lag time when running in its Game picture mode. As a means of navigation the interface is simple to get to grips with, offering an arsenal of picture, sound and feature customisations at your fingertips.
