Samsung QD-OLED S90D / S94D vs Samsung Neo QLED QN85D / QNX1D

In the HDR effect quality category, Samsung S90D achieves remarkable results. On the luminance chart up to 10% window, the TV exceeds the magical threshold of 1000 nits, which is an impressive outcome. However, in the film scenes we tested, these values were slightly lower. Additionally, in the case of a scene with fullscreen sunlight glare, brightness drops to around 500 nits, but it still remains at a very good level. It is worth mentioning that this model stands out with very high colour gamut coverage, thanks to the QD-OLED panel used, which gives it an advantage over TVs with WOLED panels that cannot achieve such a wide spectrum of colours.

Samsung QN85D leaves us with mixed feelings regarding HDR quality. It can shine in synthetic luminance tests, reaching even 1000 nits – which makes scenes like those from 'The Meg' or the start of 'Life of Pi', where the screen is all bright, look truly impressive. However, in practice, the device has its limitations – especially when smaller bright elements appear on the screen. In such moments, brightness noticeably drops, and the HDR effect loses its punch. At brightness levels around 200-300 nits, the magic of HDR simply fades away, not delivering spectacular effects. However, it’s not that the television completely disappoints – coverage of the DCI-P3 colour gamut at 95% is quite decent, although it doesn’t stand out against the best competitors. Colours are well-rendered, but it's clear that HDR could make a bigger impression if brightness could be better controlled.

Samsung 65 S90D with a QD-OLED panel has been tested in Filmmaker mode, which the manufacturer has been using for years to provide the best possible picture settings. In this mode, the TV offers a fairly decent image but with some shortcomings worth noting. In terms of white balance in HD content, viewers may notice a dominance of the red color. This effect can lead to the impression that certain skin tones appear unnatural and the overall scene will be too warm, which in turn can affect immersion in the watched material. In scenes where subtle differences in color are crucial, these distortions can be particularly noticeable. Similar sensations may also occur in 4K HDR content. Changes in white balance in this case can be analogous, with a noticeably smaller deviation in red color. This can also cause certain details and colors to not be fully represented, making the image lose its naturalness.

When it comes to contrast, the gamma presents quite well, however, some errors are still noticeable. Gamma values are below the reference level of 2.4, which can result in bright areas of the image being washed out and dark areas lacking detail. This limitation can cause some scenes to lack depth and detail, which in turn affects the overall presentation quality. On the other hand, the EOTF curve related to contrast in 4K HDR content performs really well, showing that the TV can effectively convey differences in brightness. Nevertheless, it is worth noting that these values are slightly below the ideal level on the graph, indicating the need for further optimization in this regard.

Samsung S90D in Filmmaker mode offers solid color reproduction, but requires some adjustments to fully realise the potential of the TV, especially in the context of different types of content.

Samsung QN85D TV has been tested in the best available mode – Filmmaker. While one might expect its name suggests a mode perfectly suited for films, unfortunately, it has several significant issues.

When it comes to white balance for HD content, there is a noticeable dominance of red and blue, which makes the entire image take on pinkish hues – this is also confirmed by Colour Checker tests. This effect disturbs the naturalness of skin tones and many other elements, which is particularly evident in more demanding scenes. Initially, the white balance for 4K HDR content seems correct, but at the end of the graph, there is a significant spike in blue hues, affecting the final image quality and making the colours appear unnatural.

The gamma brightness characteristic is also not ideal – although it generally stays close to the reference value, there is a slight drop below 2.4, which can impact the perceived depth of shadows. The EOTF curve responsible for 4K content does not perform any better. There is a clear boost compared to the reference curve, leading to excessive brightness in some areas, thus losing the cinematic quality that the Filmmaker mode should provide. While it might initially seem that the effect is cinematic, unfortunately, the number of errors in colour and brightness reproduction is too significant to call it flawless.

After calibrating the TV, the Samsung S90D in film mode gains quality more than one might expect. The white balance for HD and 4K HDR content has been adjusted to near perfection. Although minor shortcomings can be noticed, they are subtle enough that they don’t significantly impact the overall picture quality. The colours have become more harmonised, aiding in the natural reproduction of details, particularly in scenes that require precise colour representation. It is worth noting that this model, in this size, uses a QD-OLED panel which offers broader colour gamut coverage compared to other sizes of this model that are equipped with a WOLED panel.

The contrast has also significantly improved. After calibration, the gamma graph is much closer to the expected line, providing a better balance between light and dark tones in the picture. The EOTF curve, which before calibration indicated issues with overexposed scenes, now shows significantly better results. This effect allows for the retention of more details in the bright areas of the image, especially in HDR materials.

After professional calibration of the Filmmaker mode on the Samsung QN85D television, a significant improvement is noticeable, especially for HD/SDR content. The white balance has been completely free of major errors, and the brightness characteristics for this type of content have been significantly adjusted, allowing for a more natural and realistic image. Television, YouTube films, and other HD materials now look much better, with appropriately balanced colours and without the exaggerated hues that previously marred the experience.

However, the biggest issues arise with 4K HDR content. Despite the calibration, it's hard to speak of significant improvement in white balance here – the differences are cosmetic rather than essential. Brightness, governed by the EOTF curve, seems to be set according to the reference level in synthetic tests at first glance, but has its limitations during actual viewing in films. When analysing the EOTF curve in real film scenes, it becomes clear that the television struggles to maintain consistency in brightness. The effect is that mixed scenes still have their darkest elements boosted, leading to exaggerated contrasts, and completely dark scenes remain too dark, which negatively affects the visibility of details.

The television handles tonal transitions excellently, allowing colours to flow smoothly into each other, creating a natural image. The built-in noise reduction feature can further enhance these transitions, which can be useful in certain situations. However, it is worth remembering that activating this option may lead to excessive smoothing of the desired film grain structure, which in turn can affect the authenticity and atmosphere of the image. Therefore, caution is recommended when using this feature to avoid losing the character and depth of the content.

The Samsung S90D model effectively processes materials in lower resolutions. This can be seen in the displayed image. The model's silhouette is clear and naturally reproduced, with details well preserved. Additionally, the branches of the trees are well-defined, showing no visible jagged edges that could degrade the quality of the image. Thanks to effective upscaling, even lower resolution materials look attractive on the screen, which will surely please users enjoying a variety of content sources, such as standard cable or antenna television.

When checking the fluidity of tonal transitions in low-resolution materials on the Samsung QN85D television, it’s worth noting the noise reduction feature, which significantly improves problematic tonal transitions. On the other hand, this feature also has its downsides – it removes film grain, which is an important element of many productions, giving them authenticity, and it can also soften the image. This may appeal to those who prefer a smoother picture; however, for lovers of the authentic look of films, using this feature should be considered carefully.

Regarding image scaling, the television performs very well. The model's figure is presented correctly, without noticeable distortions, and the branches in the background do not have excessive artificial sharpness, which is often a problem when scaling lower resolution materials. The high capabilities of the image processor are evident here, which can effectively process lower quality materials, ensuring good final quality.
