Samsung Neo QLED QN85D / QNX1D vs Samsung Q8F

Samsung QN85D leaves us with mixed feelings regarding HDR quality. It can shine in synthetic brightness tests, achieving up to 1000 nits – which makes scenes like those from the film 'The Meg' or the beginning of 'Life of Pi', where the screen is entirely 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 impact. At brightness levels around 200-300 nits, the magic of HDR simply fades away, failing to deliver spectacular effects. However, it's not the case that the television completely disappoints – a DCI-P3 colour gamut coverage of 95% is quite decent, although it does not stand out against the best competitors. Colours are well-reproduced, but it's clear that HDR could make a bigger impression if brightness were better controlled.

In terms of brightness, the Samsung Q8F performs surprisingly well for a television without local dimming. In measurements, it reaches up to 500 nits, which in practice means that most movie and series scenes look pleasing, and it cannot be accused of lacking the 'HDR effect'. In films such as Life of Pi or The Meg, the screen was able to burst with brightness and deliver a light effect at a satisfying level. It struggles more in difficult moments — during dark scenes with individual bright points. The global dimming used causes the television to dim the image to maintain deep blacks, but at the expense of detail brightness. This is clearly visible in the scene from Sicario 2, where the helicopter lights dropped to around 200 nits. This is a conscious design decision that gives the impression of deeper blacks, but somewhat takes away the brightness from individual elements, and one must simply keep this in mind. In terms of colour reproduction, the Q8F uses quantum dot technology, which widens the colour gamut. A coverage of the DCI-P3 palette at 91% can be considered a decent result, although it is not a record-breaking figure compared to other QLEDs.

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

In terms of white balance for HD content, there is a clear dominance of red and blue, which causes the entire image to take on a pinkish hue – this is also confirmed by Colour Checker tests. This effect disrupts the naturalness of skin tones and many other elements, particularly noticeable in more challenging 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 shades, which impacts the final image quality, making the colours appear unnatural.

The gamma brightness characteristics are also not ideal – although it generally stays close to the reference values, there is a slight drop below the 2.4 level, which can affect the perceived depth of shadows. The EOTF curve responsible for 4K content does not present itself any better. There is a noticeable boost relative to the reference curve, which leads to excessive brightening of the image in some areas, thereby losing the cinematic quality that the Filmmaker mode should provide. Although 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.

We decided to check out the Filmmaker mode, as it provided us with the best image straight out of the box. However, this does not mean it was perfect. The white balance had too much blue and red, resulting in the white taking on a slight mauve-pink hue. Such an imbalance affected the visibility of practically all colours, as can be seen in the comparison photo below. The brightness characteristics in SDR content were quite well adjusted, though in HDR material we noticed that the television did not always manage its global dimming effectively — at times the screen was too dim, while at other moments it could suddenly brighten. Fortunately, issues related to colours can be effectively corrected with calibration tools, so we decided to get to work.

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 stripped of serious errors, and the brightness characteristics for this type of content have been significantly adjusted, allowing for a more natural and realistic image. Television, YouTube movies, and other HD materials now look much better, with appropriately balanced colours and without the excessive hues that previously spoiled the viewing experience.

However, the biggest issues concern 4K HDR content. Despite the calibration, it's difficult to speak of a serious improvement in white balance – the differences are cosmetic rather than crucial. Brightness, which is governed by the EOTF curve, appears to be set in line with the reference level in synthetic tests at first glance, but has its limitations during actual usage in films. When we analyse the EOTF curve in real film scenes, it becomes apparent how the television struggles to maintain brightness consistency. The effect is that mixed scenes still have lifted darkest elements, leading to exaggerated contrasts, while completely dark scenes remain too dark, negatively affecting the visibility of details.

After calibration, we managed to correct the white balance to near perfection. Older SDR content looks fantastic — most errors fall within a value range of 2, which is well below the threshold of perceivability for the human eye. In HDR, we also brought the white balance to an acceptable level, but another issue arises here. So why are there still relatively large errors in colour reproduction? This mainly stems from the limited colour palette and the way the television manages brightness. The global dimming technique used does not give the user control in the settings, so when analysing the EOTF curve in HDR films, it is apparent that the Q8F can modify luminance independently. This can be regarded as a certain limitation, but despite this, the picture after calibration is still much more pleasant to view than in the factory version.

When checking the smoothness of tonal transitions in low-resolution materials on the Samsung QN85D television, it is 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 more smoothed image; however, for lovers of the authentic look of films, using this feature should be considered carefully.

As for 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. You can see the high capabilities of the image processor, which can effectively process lower quality materials, ensuring good final quality.

Let’s check how the Q8F performs with older content, which often has poor quality. Let's start with the positives: the upscaling, or raising the image to a higher resolution, works really well. The television handles both traditional television and YouTube material quite competently, without giving the impression that we are dealing with something completely unattractive. It performs less well with very low resolutions, such as 576p — the image can be cropped, and unfortunately, the overscan issue cannot be turned off. Moreover, the digital processing itself appears less effective. The noise reduction feature, instead of eliminating unwanted disturbances, smooths out almost everything: film grain (which is desirable for many viewers) disappears along with the texture of the image, and the faces of the actors start to resemble characters from cheap Turkish soap operas. Therefore, it’s hard to consider this option useful — it’s best to leave it completely turned off. Perhaps Samsung will refine the operation of this function in future updates, but for now, it’s difficult to view it as anything other than an unnecessary addition.

Samsung QN85D TV is equipped with a 120 Hz refresh rate panel, which should satisfy both gamers and sports fans by providing a smooth and dynamic picture. There are options to enhance fluidity, such as the motion blur and judder reduction feature, which allows for precise adjustment of motion smoothness on a 10-point scale. Motion blur reduction increases the sharpness of fast-moving objects, making action scenes clearer, while judder reduction smooths movement, eliminating the "stuttering" effect. Smearing is generally well controlled, although there are occasional minor shortcomings that may be visible in more demanding scenes, particularly when an object moves against a dark background. Additionally, the TV offers a BFI (Black Frame Insertion) feature at 60 Hz, which can significantly improve the experience of motion fluidity, although at the cost of image flicker, which may be bothersome to some users.

Due to the applied 60 Hz matrix, it is difficult to call the Q8F a television designed for gaming or watching sports. The panel is not particularly fast, which makes motion blur noticeably visible. If you were hoping for spectacular, even 'stadium-like' experiences during broadcasts, you may feel slightly disappointed. Fortunately, in the case of films and series, Samsung has not abandoned the motion blur reduction feature. This is nothing but a motion smoother that allows you to improve the fluidity of productions recorded at 24 or 30 frames per second. This way, you can decide for yourself whether you prefer a smoother, 'television' image or to maintain a cinematic character. It all depends on the viewer's preferences, and the ability to adjust this parameter is undoubtedly a plus.

The Samsung QN85D television is an excellent choice for gamers, offering a wide range of features that enhance the gaming experience and make it even more exciting. With a refresh rate of 120 Hz, the image is incredibly smooth, which is crucial during dynamic scenes in action games. The television also features low input lag, ensuring that reactions to the player's commands are nearly instantaneous, translating to better control over the character and events on the screen.

In addition, the QN85D Samsung supports VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) technologies, which optimise image fluidity and reduce delays by automatically adjusting the television to meet the needs of gamers. Furthermore, the Xbox app allows access to cloud gaming without the need for a console, which is a significant advantage for those who want to enjoy their favourite titles without additional hardware – a solution that sets Samsung televisions apart.

The Auto Motion Plus Game feature is another element worth highlighting. This motion smoother creates the impression of a higher frame rate – as a result, games running at 30 fps appear smoother, resembling gameplay at 45 fps, while games at 60 Hz come close to 90 Hz. Most importantly, this feature does not introduce significant lag, ensuring that the gaming experience remains undisturbed. This allows players to enjoy a smoother image without compromising on responsiveness.

It is not entirely clear what Samsung has meddled with this year regarding its televisions, but the Q8F is not free from all the confusion surrounding updates and shortcomings. While its older cousin, the Q67D, could still be recommended to casual gamers with a clear conscience, it is difficult to find a reason to do so here. Apart from the automatic game mode and the attractively designed Game Bar, we receive practically nothing that could attract gaming enthusiasts. The lack of proper HGiG implementation is a significant issue, especially since after the 1126 update, the feature simply disappeared. The situation regarding VRR is even worse. Although it is listed in the manufacturer's brochures and appears in the Game Bar, we were unable to activate it. The Xbox Series X console did not allow activation at all, and the option remained greyed out and inactive. It is hard to praise such a television even to casual gamers, which is a pity, as Samsung had a strong bargaining chip in the gaming segment for years.
