Samsung QLED Q80D vs Samsung Neo QLED QN85D / QNX1D

In the context of HDR, the Samsung Q80D television achieves very positive brightness results in the tested film scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing the user to experience a great juiciness of the image. Such results allow the user to feel the difference between HDR and SDR quality. Unfortunately, problems arise in situations where small light effects occur against a dark background. In such cases (e.g. test pattern 4 from the film Sicario 2), a noticeable drop in brightness can be observed, caused by the large sizes of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements against a dark background. At that point, we may perceive an unwanted lack of brightness, and the HDR effect resembles that of SDR.

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 "Filmmaker" mode, which is the best choice out of the box, the Samsung Q80D TV shows solid colour reproduction. For SDR content, a visible drop at the beginning of the gamma curve suggests that details in dark scenes may be less pronounced, impacting the overall viewing experience. Regarding white balance in SDR content, while it is generally accurate, significant drops in blue colour when screen coverage exceeds 70% can result in less natural hues in bright and dark scenes. Users may notice that some blue elements in the image may appear less intense, and the overall colour will have a warmer tint.

In contrast, for HDR content, the EOTF curve being above the reference line for most of the time indicates that the TV may struggle with accurately reproducing brightness and details in the brighter areas of the image, which may be disadvantageous for the viewer. It is also worth noting the substantial drop at the beginning of this graph, indicating that the TV has difficulties reproducing brightness in the darker areas of the image, as seen in the contrast and black tests, where several scenes were unable to showcase the full capabilities of the TV's brightness. In terms of its white balance, the initially good results on the graph are promising, but the sharp drop in red colour, which significantly falls down, combined with a large increase in blue colour, may lead to inaccuracies in reproducing certain skin tones and other key colours. This phenomenon may be noticeable to viewers in scenes where colour details are crucial.

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.

The film mode after calibration looks significantly better than the one you can see when taken out of the box. Samsung offers an advanced range of calibration tools in its televisions. Among them are 2- and 20-point greyscale adjustment and CMS (Colour Management System). Both in HDR and SDR mode, the white balance has improved significantly, although there are minor errors at the end of the graph in the case of HDR content. The contrast has also been greatly improved, and the gamma curve responsible for SDR shows better results. However, when it comes to HDR, the EOTF curve in the television seems to be at an ideal level at first glance. Yet, when we delve deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. One could even say that the television is "cheating" when playing film materials. Such a situation, where the EOTF curve is above the reference line, makes the screen – although it may seem brighter, which some users may find attractive – lose detail in the darker parts of the image. In practice, this means that in scenes with a lot of shadows or dark elements, the television is unable to accurately render the details that should be visible.

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.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle grading, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes elements that should not be smoothed, such as film grain, to become blurred. For those who value a pliable, smoothed image more, this can be seen as a significant advantage, especially for lower-quality content.

When it comes to image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing viewing comfort. The television handles the conversion of lower-resolution materials well, improving their quality and detail. For example, in the attached image with the model, there are no visible artifacts or excessive fraying of branches, which attests to the advanced image processing technology.

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.

The Samsung Q80D television stands out very positively in terms of motion fluidity and motion blur reduction, primarily due to the applied 120Hz panel and above-average response time of the panel. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustment of smoothness on a 10-point scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of rapidly moving objects. In the UFO test, no motion blur is visible behind the moving object, and the image is not cloned forward, indicating a lack of overshoot effect.

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.

The Samsung Q80D television is a true gem for gamers. It is equipped with four HDMI 2.1 ports, which is a rarity, especially in this price range. This allows users to enjoy features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and 120Hz in 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The television also supports HGIG (HDR Gaming Interest Group), enabling optimal display of HDR content in games. Additionally, it is equipped with a Game Bar that allows quick access to gaming settings. Users of Nvidia graphics cards will also be pleased thanks to the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision mode, which may be disappointing for users looking for this HDR format. It is also worth mentioning that since 2022, thanks to a partnership with Microsoft, Samsung televisions offer the Xbox Game Pass application, allowing for cloud gaming. This is an additional advantage for gamers who want to access a wide library of games without the need for a console.

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.
