Samsung Neo QLED QN95D vs Samsung S90H (WOLED)

Samsung QN95D handles HDR exceptionally well, achieving a peak brightness of around 2000 nits. In the tested movie scenes, where the screen is fully lit, the television provides intense and realistic representation of HDR content, significantly enhancing the visual experience. Nevertheless, similar to contrast, the dimming algorithm may sometimes show limitations. Despite the considerable number of Mini LED zones, the television does not surprise the user with incredible brightness. For instance, in scenes from the film "Life of Pi," where a bright moon appears against a dark background, and in excerpts from "Sicario 2," where a strong light effect occurs on a dark background, the television displays very poor results. At such moments, the television attempts to reduce the halo effect by darkening the image to a level reminiscent of SDR quality. As a result, blacks appear deep and uniform, but this comes at the cost of losing some detail in bright areas. It is a compromise aimed at maintaining the best possible quality of black, although it simultaneously causes the image to lose a bit of its dynamism. Despite certain flaws in the operation of the local dimming algorithm, this television deserves praise for its wide coverage of the DCI-P3 colour gamut. This is made possible by the use of a quantum dot coating, also known as QLED technology, which allows for vibrant and rich 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.

In the category of factory colour reproduction, the television Samsung QN95D was tested in Filmmaker mode, which offers the best settings from the manufacturer. Nevertheless, it is not entirely free from flaws. In the case of HD content, there is a noticeable colour deviation, particularly in white balance, where the red colour clearly dominates the graph. The situation improves with 4K HDR content; however, there are still significant drops in blue colour reproduction. These effects can be observed in a scene from the film "Star Wars," where the protagonist is depicted in overly warm tones.

As for contrast, we can observe an initial large jump on the gamma graph, indicating that the television effectively highlights the brighter parts of the image. However, at the end of the graph, we notice a distinct drop, which may mean that in darker tones, details can be lost. Such a shape of the gamma curve can affect the way users perceive dark scenes, where some details may become too blurred or too dark, causing the image to lose clarity. It is also worth noting the curve responsible for brightness (EOTF), which is quite correct, except for the initial drop.

Although Samsung QN95D boasts impressive parameters and advanced technologies to deserve the title of one of the best televisions on the market, it requires certain adjustments in colour reproduction and contrast to fully utilise its potential.

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 calibration, the picture on the Samsung QN95D television achieves truly impressive results. The white balance is perfectly aligned, and error readings rarely exceed 2, which means that colours are displayed very accurately. Most samples from the Color Checker test fall within an acceptable error range, confirming that the television reproduces hues excellently. The contrast has also improved significantly, and the gamma curve is more stable, resulting in better visibility of details in both dark and bright scenes. However, it is worth noting the EOTF (Electro-Optical Transfer Function) curve, which shows some discrepancies in film tests. Although the television performs well in most scenes, details in the blacks can still be lost in more extreme cases – this is due to an aggressive dimming algorithm.

Nevertheless, these minor imperfections do not detract from the overall picture quality. After calibration, the Samsung QN95D impresses with its visual quality, offering an exceptional experience that will certainly satisfy anyone looking for a top-tier television.

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.

The Samsung QN95D television handles tonal transitions even in lower quality materials, thanks to the noise reduction feature employed, which functions like a gentle gradation. This feature is extremely effective, smoothing out the image and eliminating unwanted noise while significantly improving the quality of the displayed material. However, as is often the case, too much effectiveness can lead to unintended side effects. In some materials, this feature may also blur elements that should remain sharp, such as film grain.

Despite this, the television performs well in the context of image scaling, eliminating larger jagged edges. In a scene where branches are visible, they are not excessively artificially sharpened, allowing for a natural appearance, and the model does not have an artificial outline. Overall, this means that even in more challenging conditions, the film material presents itself satisfactorily on the Samsung QN95D. The only downside when watching HD/SD content (such as regular terrestrial television) is the fact that we have a slightly cropped image – this is caused by the so-called overscan, which cannot be turned off.

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.

The panel in Samsung QN95 performs very well in terms of motion blur and smoothness of movement. With a refresh rate of 120 Hz and features for reducing blur and judder, the picture settings can be customised to personal preferences, whether for watching films or for dynamic sports broadcasts. The user has the option to adjust the smoothness of the image on a 10-point scale – from a more frame-like appearance reminiscent of traditional film to a smooth, almost theatrical effect, which works particularly well for sports transmissions.

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.

Samsung QN95D offers quite a few features that gamers will appreciate. First and foremost, the television supports variable refresh rate (VRR), which allows for smoother gameplay, eliminating issues with tearing, especially during dynamic scenes. We also find the auto low latency mode (ALLM) feature, which automatically switches the television to low latency mode when it detects a connected console or computer, ensuring more responsive controls.

Furthermore, the QN95D Samsung has a game mode that reduces input lag to a very low level, which is crucial in games where reflexes play an important role. With a high refresh rate of 120 Hz, the picture is exceptionally smooth, significantly enhancing the experience of fast-paced action games and sports productions. The television also supports G-Sync and FreeSync technologies, which further enhance gameplay smoothness and improve user comfort. An interesting addition is the 'Game Bar' – a special menu that provides quick access to all game-related settings, allowing easy adjustments of picture and parameters to suit user preferences without the need to interrupt gameplay.

Although the Samsung QN95D does not support Dolby Vision – which is quite obvious for Samsung televisions – it does offer the HGiG feature, which ensures appropriate picture quality in HDR games, in line with the creators' vision.

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.
