Samsung Neo QLED QN85D / QNX1D vs Dreame S100

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.

The Dreame S100 is a relatively bright television. In movie mode, the brightness we measured reached around 600 nits. This is a really good result, although not the highest when considering the competition at this price point. In fullscreen scenes, it is evident that the television can produce an image that impresses with its brightness. Unfortunately, when more complex scenes appeared on the screen, the local dimming algorithm in this model primarily focused on maintaining the deepest blacks. However, this came at the expense of HDR performance – and in a drastic manner. In such scenes, the brightness of bright elements dropped below 100 nits, which is a frankly tragic result, far from any HDR effect. One can improve this aspect, but not without a "however." It is simply necessary to change the local dimming setting in the television's menu, but then the blacks in such scenes simply become grey. It's a pity that Dreame couldn't better refine the local dimming algorithms, and the S100 is another example that the sheer number of local dimming zones does not always translate to a better image. As a consolation, it is worth adding that the Dreame S100 is advertised as a "QLED" type television, although in reality it uses a PFS LED filter. As a result, the colours are appropriately saturated, and the colour gamut coverage of DCI-P3 we measured exceeded 94%.

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 tested the Dreame S100 in 'movie' mode and we definitely recommend using this setting for watching all types of content. Interestingly, within the deeper settings of the television, we also find a dedicated 'Filmmaker' mode, which is now available from almost every manufacturer. However, in the case of the Dreame S100, we do not recommend using it – it blocks all settings related to the picture and does not allow for any configuration in the menu - even motion smoothing. So, how do the factory colours of the S100 fare? Not too badly, but also not the best. The television itself was quite heavily tinted with blue components, which is clearly visible in our white balance measurements. This made the picture artificially brightened, and the colours had a slight bluish tint. This is confirmed by the Color Checker palette, which showed how the colour samples tend to drift towards blue, generating quite significant colour errors. The picture in HDR mode looked definitely better, where the colour errors were not as prominent, although they still fell far from perfection. Here, the white balance was also shifted too much towards blue, causing considerable errors in colour reproduction.

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.

The Dreame S100 has proven to be a device very amenable to professional calibration. In its menu, we found a plethora of advanced options that allowed us to effectively correct factory errors. Thanks to advanced white balance correction – both in SDR and HDR content – we completely eliminated the excess blue components. The image immediately became much more natural and pleasant to the eye. After fully tuning the colours, the errors in the Color Checker test dropped below Delta E values of 2-3. For the average viewer, this means that any colour distortions have become nearly impossible to perceive with the naked eye. This is truly a pleasant surprise, as new brands in the television market often encounter significant issues with the correct implementation and functioning of sliders in the calibration menu. Here, everything worked as it should. The only thing we must criticise is the way the television manages its brightness in HDR. Due to the specific nature of the local dimming algorithms, anomalies can be seen on the EOTF curve we measured. Where high highlights should appear, there is a slight boosting of the curve above the reference line. In practice, this causes an unnatural brightening of some of the brightest elements in films or games. Despite this minor flaw, professional calibration brings about a huge, very positive change in this model.

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.

For scaling and digital processing in the Dreame S100, the technology that the manufacturer proudly calls Dreamind™ Pro AI is responsible. However, it must be clearly stated that this is not a proprietary processor, but merely a marketing name for a chip made by MediaTek – more precisely, the MT5889 model. Unfortunately, we are talking about a rather outdated unit, from a time when MediaTek lagged significantly behind the competition in terms of performance. This unfortunately has a direct impact on the image as that is what this chip also deals with. The upscaling in the S100 is quite mediocre, and the processor has a tendency to heavily and artificially sharpen edges (fortunately, this can be somewhat tempered with the sharpness slider in the menu). In the options, we also find the "Contour Smoothing" feature, which theoretically is supposed to improve tonal transitions. In practice, it offers almost no improvement – setting it to any level rarely eliminates visible banding of colours, but it can unnecessarily blur elements of the image that should remain sharp.

A separate issue is the phenomenon of overscan (cropping the edges of the frame), which is noticeable here practically all the time. Although there is an option to set the screen to display the full frame in low-resolution materials, this requires activating the previously mentioned Filmmaker mode. And as you know, this mode completely blocks the adjustment of any other sliders in the picture menu. In our test tables, we marked that the television offers an option to disable overscan, as technically such a function exists in the system – however, in everyday use, when maintaining sensible image settings, you will not be able to take advantage of it.

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.

When it comes to motion fluidity, the Dreame S100 performs really well. It features a panel with a refresh rate of 144 Hz, although in reality, the vast majority of people using it in a traditional way will still be limited to 120 Hz (as this is the maximum supported by today's equipment apart from PCs). Thanks to the high refresh rate, the image in motion remains really sharp, largely thanks to the well-functioning MEMC smoother. In the menu, we find predefined modes that allow the television to efficiently generate artificial frames, which effectively improves the fluidity of dynamic sports scenes, but also eliminates image stuttering in film and series materials recorded at 24 frames.

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.

The Dreame S100 seems almost like the perfect screen for a gamer. The television is equipped with 2 HDMI 2.1 ports with a bandwidth of 40 Gbps, which means that functions like automatic game mode (ALLM) and variable refresh rate (VRR) ranging from 48 to 144 Hz work seamlessly on consoles. It also features a well-designed gaming panel (Game Bar), allowing users to continuously monitor important parameters—from active picture modes to the number of frames rendered by the console, and even the option to add a crosshair in the middle of the screen. All of this looks great on paper; however, the biggest problem with the S100 is the implementation of HDR mode in games. The television does not have the HGiG format implemented correctly. As a result, an unsuspecting user may incorrectly configure the console when first using the screen. Poor configuration can lead to an image that is too dark or too washed out (as a guideline: we suggest setting the brightness in the Xbox console menu to around 600 nits, and in the PS5 to 12 clicks). The Dolby Vision format also proves problematic, as it often would not activate at all between the XBOX and Dreame S100. And when it was finally managed to be activated, playing was not possible due to a very high input lag often exceeding 100ms. If the manufacturer can improve the HDR issue in games via an update, the S100 will be truly excellent hardware for gamers. For now, however, compromises need to be accepted.
