LG QNED80A6A (IPS) vs Samsung S90H (WOLED)

When it comes to image dynamics and brightness, the QNED80A firmly stands its ground. It is not a “bright beast” – during our measurements, peak luminance oscillated between 350-400 nits. To put it plainly: these values won't allow HDR formats to fully spread their wings. So, do not expect that the glare of the sun or car headlights in films will blind you. However, this television has a powerful ace up its sleeve that salvages the overall picture impression – and that is the colours. LG's engineers have employed an advanced filtration system (technically most likely based on PFS phosphor, marketed as QNED/NanoCell), which does a fantastic job. Thanks to this, despite average brightness, the screen is capable of generating exceptionally saturated and pure hues. Our instruments showed coverage of the wide DCI-P3 cinema colour palette at a level of 93-94%. This is a result that outclasses most standard LCD televisions. In practice, this means that when watching 4K HDR content, the picture – although not very bright – is very plastic, vivid, and delights the eye with its depth of colours.

Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price bracket, although compared with the QD-OLED version it is slightly dimmer. The difference is not as significant as in last year’s F series, where the gap could reach as much as 500 nits. Here the parameters of both panels are very similar, and differences in peak brightness are only in the order of 100–150 nits. In small-area measurements the S90H on the WOLED panel easily reaches levels close to 1500 nits. Such a reserve of power allows HDR dynamics to be reproduced phenomenally; all highlights, light reflections and explosions have the necessary punch, exactly as the creators intended in the editing studio. As with most OLED displays, when a very bright scene fills the whole screen protection systems activate and brightness naturally falls to around 700 nits. It is worth emphasising that this is still an excellent result on the market. Often noticeably better than many Mini LED screens in the same segment.

Colour gamut coverage

The biggest difference between the two S90H variants lies in colour reproduction and saturation. This results directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a consequence, colours at very high brightness do not reach the same intense saturation, and the volume of the wide gamut is somewhat more limited than in QD-OLED. That does not change the fact that in everyday use these differences will be hard for most viewers to spot. The DCI-P3 space we measured reaches nearly 99% on the WOLED panel, which means that in the vast majority of real film scenes both variants will present an almost identical picture. The true distance only reveals itself in rarer, exceptionally demanding productions that use the ultra-wide BT.2020 gamut. Due to the specifics of the WOLED panel’s construction, coverage of that standard is about 15% lower compared with the S90HAT with a QD-OLED panel, so the brightest, heavily lit colours in HDR may appear slightly less vivid.

Here, regardless of whether you encounter the VA or IPS version, the situation is identical. LG engineers once again served us their vision of a "gaming look," which unfortunately has little to do with accuracy. When switched to console mode, the white balance automatically drifts towards very cold regions. The image is dominated by the colour blue, which makes it seem artificially sharpened, and the white is so aggressive that it appears burnt out. This creates an effect we associate with vibrant shop modes – everything is meant to shine and scream "I am digital." While some may appreciate this, we must say plainly: the image is not accurate. If you care about naturalness, we suggest you immediately check the settings and change the colour temperature to a warmer one.

In Filmmaker mode, which we strongly recommend switching on straight out of the box, the S90H offers very good factory colour tuning. Colours are natural and faithful to the creators' intent, without the irritating oversaturation found in more aggressive presets. However, as is often the case without full calibration, no two units are identical. In our test the white balance was slightly lacking in blue, causing the image to lean a little towards warmer, yellowish tones. This was most noticeable in bright scenes, such as the snowy sequences from Star Wars. Additionally, the gamma curve was slightly low at 2.2, which produced a minor lift in shadow detail. In HDR mode the tuning was somewhat better, showing only a slight undersaturation in the red region.

After professional calibration, the QNED80A in the IPS version has changed unrecognisably, especially with "ordinary" content (SDR). We managed to eliminate the greenish tint and calm down the overly bright gamma. In classic television or older games, colour errors (DeltaE) have dropped below the threshold of perception (value < 2). The picture is now coherent, natural, and truly pleasing to the eye. The situation is somewhat more complicated in HDR mode. Although the colours are now in place, the television has a problem with perfectly controlling the brightness (EOTF curve). Due to the limitations of edge lighting and the rather meagre adjustment options provided by LG in this respect, the television's software at times "does what it wants," just to mask the imperfections of black and contrast. However, this is not a cause for concern – despite these technical limitations, the picture after calibration is a class better than what you saw out of the box.

After a full calibration it’s fair to say the S90H in WOLED guise looks almost perfect. In SDR mode colour inaccuracies drop to ultra-low levels and Delta E values very rarely exceed 2. That’s a phenomenal result, so if you care about perfectly faithful colour reproduction it’s definitely worth considering calibration. The calibrated HDR mode also performs very well, with the white balance stabilised and earlier deviations eliminated. After professional fine-tuning it’s really hard to find anything to criticise, because the TV delivers an image with almost reference-level naturalness and three-dimensionality. The slightly lower score in this category compared with the QD-OLED variant is solely due to the aforementioned limitation in saturation in extremely bright scenes; the tuning options and colour fidelity themselves are at the highest level.

It often happens that cheap 4K TVs mercilessly expose the flaws of low-resolution materials. Here, it is different. The QNED80A is great equipment for watching content that is not perfect. The processor does a good job of upscaling the image, making even older recordings look quite decent on a 4K screen – they are consistent and free of digital noise. Interestingly, there is a gradation reduction feature available in the settings. It is very effective in combating the so-called banding in low bitrate materials. Of course, it should be approached with some caution. Due to the lower processing power of the chip (compared to the premium series), turning on this option can sometimes result in unwanted artifacts or blurriness. Despite this risk, we encourage experimentation, as in many cases this feature can save a poor-quality viewing experience.

In terms of posterisation reduction itself, Samsung has kept the solutions known from last year’s models. The dedicated gradient-smoothing function performs quite well and can effectively mask unwanted tonal banding, which is useful on a WOLED panel that is slightly more prone to banding. However, you should be aware of its aggressive behaviour. This mechanism, alongside the artefacts themselves, can clean up fine film grain and gently soften detail. Ultimately it is a matter of compromise, but if you want an absolutely faithful reproduction, it is safer to leave this option off.

Similarly, in the area of scaling it is difficult to call this a breakthrough. The S90H uses the same NQ4 Gen3 processor as its predecessor, so the upscaling quality was almost identical. The chip sharpens lower-resolution material very well, extracting a satisfying level of detail. Samsung still has not dealt with the longstanding overscan issue, though. With some older recordings or archive footage the edges of the image can be slightly cropped. It’s a minor flaw, but it’s a pity the manufacturer still hasn’t eliminated it.

In terms of motion reproduction, the QNED80A unfortunately has a tough time. The television is based on a display with a refresh rate of 60Hz, which is quite a disappointment for the QNED series in 2025. If you are looking for perfect sharpness during dynamic football matches, you may feel somewhat unsatisfied. A solution in this situation is the TruMotion system. It allows for artificial frame generation, which smooths out the image in films and series. In the menu, you will find a De-Judder slider – we recommend setting it to a value of 2, 3, or 4. This is the "golden mean" that improves fluidity without turning the film into a soap opera.

In terms of motion handling, the S90H is simply excellent. This year's panel offers a boosted refresh rate of up to 165 Hz, though in practice the benefit will mainly be for gamers connecting a high-end PC. For films, series or sports broadcasts such a high refresh rate makes no difference and the picture looks exactly the same as at the standard 120 Hz. Regardless of the source, however, the OLED panel's lightning-fast response time does its job, so motion is clean and the ghosting or smearing familiar from LCD screens simply does not occur here.

In the gaming section, we won't be pulling the wool over your eyes – the QNED80A is not e-sports equipment. The lack of 120Hz signal support is a fact that must be accepted. However, LG's engineers have done everything possible to maximise the potential of this 60Hz panel, providing gamers with a set of desirable features. First and foremost, the television supports VRR (in the range of 48-60Hz) and ALLM. This means that the image is smooth, not choppy, and the television automatically switches to low-latency mode as soon as we pick up the controller. Accessing these options is incredibly simple thanks to the dedicated system overlay – Game Dashboard. It’s also worth appreciating the support for the HGiG format. This is a nod to owners of modern consoles. Although the screen does not support gaming Dolby Vision, HGiG ensures that the television 'understands' how to display games in HDR. As a result, we avoid the problem of blown-out clouds, which is unfortunately a plague on cheaper LCD televisions.

Players should feel at home with the S90H, because Samsung has left few reasons to complain in that respect. The TV has four HDMI 2.1 ports, each of which supports VRR, ALLM and high refresh rates. There’s also the Game Bar, a handy menu that lets you quickly check key parameters and change settings without leaving the game. Importantly, Samsung has also improved HGiG mode. In last year’s models it could cause problems when used with a console, but on the S90H it now works as it should. What really stands out against the competition is the Game Motion Plus feature. It’s a special motion smoothing mode for games that works best with titles running at 30 or 60 fps. Motion becomes noticeably smoother, while latency remains at a reasonable level. In our measurements it was under 50 ms, so gaming is still comfortable. That’s important, because on many TVs enabling a similar smoothing feature causes such a large increase in input lag that controls become noticeably sluggish. Samsung has managed to find a good compromise here. There’s still no Dolby Vision Gaming, but in practice Game Motion Plus may prove to be a much more useful feature.
