Samsung QLED Q80D vs Samsung Neo QLED QN85D / QNX1D

In the context of HDR, the Samsung Q80D television, as expected, achieves very positive brightness results in the tested movie scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing for a great juiciness of the image. Such results enable 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., the 4th test screen from the film Sicario 2), a noticeable drop in brightness is observed, which is caused by the large size of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements on a dark background. At that point, we may experience an undesired 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 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.

In "Filmmaker" mode, which is the best choice right out of the box, the Samsung Q80D television shows solid colour reproduction. For SDR content, a noticeable drop at the start of the gamma curve suggests that details in dark scenes may be less clear, affecting the overall viewing experience. Regarding white balance in SDR content, while generally correct, significant drops in blue at screen coverage above 70% can result in less natural shades in both bright and dark scenes. Users may notice that some blue elements in the image may appear less vibrant, and the overall colour will have a warmer hue.

In HDR content, the EOTF curve being above the reference line for most of the time indicates that the television may struggle to accurately reproduce brightness and details in the brighter parts of the image, which can be detrimental for the viewer. It is also worth noting the significant drop at the start of this chart, indicating that the television has difficulty reproducing brightness in the darker parts of the image, as seen in the contrast and black test, where several scenes were unable to show the full capabilities of the television’s brightness. In terms of its white balance, the initially good performance on the graph is promising, but the steep decline in red, coupled with a significant increase in blue, can lead to inaccuracies in reproducing some 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. 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.

The movie mode after calibration looks significantly better than the one you see right 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 (Color Management System). Both in HDR and SDR mode, white balance has improved significantly, although there are slight errors at the end of the graph for HDR content. 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 on the television appears to be at an ideal level at first glance. However, when we dig a bit deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. You could even say that the television is "cheating" when playing film material. Such a situation, where the EOTF curve is above the reference line, causes the screen – although it may appear brighter, which some users might find appealing – to 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 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.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle gradation, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes it to blur elements that shouldn't be smoothed, such as film grain. For those who prioritise a plastic, smooth image, this can be seen as a significant advantage, especially with lower-quality content.

In terms of image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing the viewing comfort. The TV handles the conversion of lower-resolution materials, improving their quality and details. For example, in the attached image featuring a model, there are no visible artefacts or excessive fraying of branches, which demonstrates advanced image processing technology.

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.

The Samsung Q80D television stands out very positively in terms of motion fluidity and minimizing blur, mainly due to the 120Hz panel and above-average panel response time. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustments in a 10-step scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of fast-moving objects. In the UFO test, there is no blurring behind the moving object, and the image is not cloned forward, indicating the absence of an overshoot effect.

Samsung QN85D TV is equipped with a 120 Hz refresh rate panel, which should satisfy both gamers and sports enthusiasts by offering a smooth and dynamic image. There are options to enhance fluidity, such as the blur and judder reduction feature, which allows precise motion fluidity adjustments on a 10-point scale. The blur reduction increases the sharpness of fast-moving objects, making action scenes more readable, while judder reduction smooths out motion, eliminating the “judder” effect. Ghosting is generally well controlled, though minor imperfections can be visible in more demanding scenes, especially when an object moves against a dark background. Additionally, the TV offers a BFI (Black Frame Insertion) feature at a 60 Hz refresh rate, which can significantly improve motion fluidity experience, although at the cost of image flicker, which might be bothersome for some users.

The Samsung Q80D TV is a real 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 at 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The TV also supports HGIG (HDR Gaming Interest Group), enabling optimal HDR content display in games. Additionally, it comes with a Game Bar, providing quick access to gaming settings. Users with Nvidia graphics cards will also be pleased with the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision, which may be disappointing for users looking for that HDR format. It's also worth mentioning that since 2022, thanks to the collaboration with Microsoft, Samsung TVs offer the Xbox Game Pass app, allowing for cloud gaming. This is an added bonus for gamers who want to take advantage of a wide library of games without needing 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 120 Hz refresh rate panel, the image is incredibly smooth, which is crucial during dynamic scenes in action games. The television also boasts low input lag, allowing for nearly instant reactions to player commands, which translates into better control over characters 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 smoothness and reduce delays by automatically adjusting the television to the needs of gamers. Moreover, the Xbox app allows for cloud gaming without the need for a console, which is a big plus for those who want to enjoy their favourite titles without additional hardware – a feature that sets Samsung televisions apart.

The Auto Motion Plus Game feature is another aspect worth highlighting. This motion smoothing technology creates the illusion of more frames per second – as a result, games at 30 fps appear smoother, resembling gameplay at 45 fps, while games at 60 Hz come closer to 90 Hz. Most importantly, this feature does not introduce significant lag, ensuring that gaming comfort is not compromised. This allows gamers to enjoy a smoother image without compromising responsiveness.
