Samsung DU7192 (IPS) vs Samsung Neo QLED QN95D

The maximum luminance in HDR materials is 245 nits, which is often surpassed by even lower results. Such values will definitely not be sufficient for comfortable viewing of HDR materials due to the lack of appropriate image dynamics and colour inaccuracies caused by the low brightness of the unit. Although the manufacturer has equipped its device with HDR format offering dynamic metadata, HDR10+, which is what we are referring to, is very rarely used compared to Dolby Vision, which Samsung has not yet introduced in its televisions. It is also worth mentioning that Samsung DU7192 offers only 82% coverage of the wide DCI-P3 colour gamut, which is another reason we should not supply a signal in wide dynamic range, as colour losses will be very noticeable. Samsung DU7192 provides high-quality images that will satisfy most users.

Samsung QN95D handles HDR exceptionally well, achieving a peak brightness of around 2000 nits. In the tested movie scenes, where the screen is fully lit, the television provides intense and realistic representation of HDR content, significantly enhancing the visual experience. Nevertheless, similar to contrast, the dimming algorithm may sometimes show limitations. Despite the considerable number of Mini LED zones, the television does not surprise the user with incredible brightness. For instance, in scenes from the film "Life of Pi," where a bright moon appears against a dark background, and in excerpts from "Sicario 2," where a strong light effect occurs on a dark background, the television displays very poor results. At such moments, the television attempts to reduce the halo effect by darkening the image to a level reminiscent of SDR quality. As a result, blacks appear deep and uniform, but this comes at the cost of losing some detail in bright areas. It is a compromise aimed at maintaining the best possible quality of black, although it simultaneously causes the image to lose a bit of its dynamism. Despite certain flaws in the operation of the local dimming algorithm, this television deserves praise for its wide coverage of the DCI-P3 colour gamut. This is made possible by the use of a quantum dot coating, also known as QLED technology, which allows for vibrant and rich colours.

The best factory mode we used throughout the testing process was "Filmmaker". This, like the vast majority of modes, had its drawbacks. Starting with the most basic chart, which is the white balance, we can notice a pronounced dominance of red, both in SDR and HDR modes. Although there was also some green in the latter, it did not significantly affect the overall impression. A chart with such results, in both cases, gives us an image characterised by strong yellowing, clearly visible on whites and on the faces of the actors. Another important chart, if not more important, is gamma. This, which is meant to control contrast in materials with a standard colour palette, was quite good in factory mode with one caveat regarding the low end. In the darkest scenes, it was significantly lowered, which led to strong brightening, resulting in the film lacking contrast and all suspense. As we mentioned, HDR materials in terms of white balance remained at a similar level. The main change is the EOTF curve chart. At the very beginning, we can observe a bulge, which, just like in the case of gamma, significantly brightened the darkest scenes. However, the chart then changed its characteristics significantly and the measured result dipped below the reference line, causing the film to lose even more dynamics.

In the category of factory colour reproduction, the television Samsung QN95D was tested in Filmmaker mode, which offers the best settings from the manufacturer. Nevertheless, it is not entirely free from flaws. In the case of HD content, there is a noticeable colour deviation, particularly in white balance, where the red colour clearly dominates the graph. The situation improves with 4K HDR content; however, there are still significant drops in blue colour reproduction. These effects can be observed in a scene from the film "Star Wars," where the protagonist is depicted in overly warm tones.

As for contrast, we can observe an initial large jump on the gamma graph, indicating that the television effectively highlights the brighter parts of the image. However, at the end of the graph, we notice a distinct drop, which may mean that in darker tones, details can be lost. Such a shape of the gamma curve can affect the way users perceive dark scenes, where some details may become too blurred or too dark, causing the image to lose clarity. It is also worth noting the curve responsible for brightness (EOTF), which is quite correct, except for the initial drop.

Although Samsung QN95D boasts impressive parameters and advanced technologies to deserve the title of one of the best televisions on the market, it requires certain adjustments in colour reproduction and contrast to fully utilise its potential.

Samsung has equipped even its lowest-end televisions with advanced tools for the calibration process. So we got to work, and the results of our efforts are more than satisfactory. The white balance, which previously had a strong yellow tint in both scenarios, now looks much, much better, even if there are slight deviations from the norm. The image will still look significantly cleaner than it did before the calibration process. We managed to model the gamma in SDR materials very well, ensuring that the image will be as contrasty as the television allows. The EOTF curve has also changed its face and no longer brightens or darkens the image in such a drastic way. However, it's worth mentioning that in the case of HDR materials, deltaE errors are still very high, but this is due to the insufficient brightness of the unit.

After calibration, the picture on the Samsung QN95D television achieves truly impressive results. The white balance is perfectly aligned, and error readings rarely exceed 2, which means that colours are displayed very accurately. Most samples from the Color Checker test fall within an acceptable error range, confirming that the television reproduces hues excellently. The contrast has also improved significantly, and the gamma curve is more stable, resulting in better visibility of details in both dark and bright scenes. However, it is worth noting the EOTF (Electro-Optical Transfer Function) curve, which shows some discrepancies in film tests. Although the television performs well in most scenes, details in the blacks can still be lost in more extreme cases – this is due to an aggressive dimming algorithm.

Nevertheless, these minor imperfections do not detract from the overall picture quality. After calibration, the Samsung QN95D impresses with its visual quality, offering an exceptional experience that will certainly satisfy anyone looking for a top-tier television.

Let's return for a moment to the feature of smoothing tonal transitions. We can set it in only two ways - off and auto. As one can easily guess, the former causes significant problems with gradation. However, if we set the latter, both films and series will offer us smooth transitions of colours. It is worth mentioning, though, that this feature has its drawbacks. It greatly interferes with the director's intent, softens the film grain effect, and, what’s worse, often misinterprets small details, also blurring them. In light of this, we conclude that the feature does not exist and do not recommend using it, as this is exactly how the tests of smoothness of tonal transitions were conducted on the tested display.

The next thing we will check in this paragraph is the image scaling process, which is extremely important when watching materials in a lower resolution. Unfortunately, as this is the manufacturer's lowest model, this function does not work very well. All details are heavily blurred, and a characteristic white halo surrounds the characters.

The Samsung QN95D television handles tonal transitions even in lower quality materials, thanks to the noise reduction feature employed, which functions like a gentle gradation. This feature is extremely effective, smoothing out the image and eliminating unwanted noise while significantly improving the quality of the displayed material. However, as is often the case, too much effectiveness can lead to unintended side effects. In some materials, this feature may also blur elements that should remain sharp, such as film grain.

Despite this, the television performs well in the context of image scaling, eliminating larger jagged edges. In a scene where branches are visible, they are not excessively artificially sharpened, allowing for a natural appearance, and the model does not have an artificial outline. Overall, this means that even in more challenging conditions, the film material presents itself satisfactorily on the Samsung QN95D. The only downside when watching HD/SD content (such as regular terrestrial television) is the fact that we have a slightly cropped image – this is caused by the so-called overscan, which cannot be turned off.

Despite the fact that Samsung DU7192 is the lowest model in the manufacturer's portfolio, it has been implemented with a motion smoothing system. Although it is quite limited in features compared to higher models, its existence is a considerable advantage in the context of competition from similar price ranges. The maximum refresh rate we will provide to the tested television is 60 Hz, which is entirely sufficient for movies and series, although not for sports. In the motion smoothing menu, we find two functions responsible for improving fluidity. These are "Motion Blur Reduction" and "Clear Motion (LED)". We will discuss the latter a bit later. Let us focus on the former, as it is quite puzzling. Unfortunately, despite its presence, we did not find any usefulness. On each of the settings, the image looked the same, with the characteristic judder known from materials recorded at 24 fps.

The matrix of Samsung DU7192 features an average response time. It is worth mentioning that due to this particular type of matrix, it is better than VA matrices in a similar price range. Therefore, it can be exceptionally said that it will not be the worst in the context of watching sports.

The panel in Samsung QN95 performs very well in terms of motion blur and smoothness of movement. With a refresh rate of 120 Hz and features for reducing blur and judder, the picture settings can be customised to personal preferences, whether for watching films or for dynamic sports broadcasts. The user has the option to adjust the smoothness of the image on a 10-point scale – from a more frame-like appearance reminiscent of traditional film to a smooth, almost theatrical effect, which works particularly well for sports transmissions.

The Samsung DU7192 television is equipped only with HDMI 2.0 ports, which is not surprising given the price of the device and its consumer profile. Therefore, it’s also logical that we won’t achieve maximum quality on the latest generation consoles. Thus, it only has the most basic feature for gamers, which is ALLM. It's a pity that the manufacturer didn’t implement at least GameBar, as it is currently a standard, even in lower-end televisions, and could introduce significant conveniences regarding quick changes to settings.

Samsung QN95D offers quite a few features that gamers will appreciate. First and foremost, the television supports variable refresh rate (VRR), which allows for smoother gameplay, eliminating issues with tearing, especially during dynamic scenes. We also find the auto low latency mode (ALLM) feature, which automatically switches the television to low latency mode when it detects a connected console or computer, ensuring more responsive controls.

Furthermore, the QN95D Samsung has a game mode that reduces input lag to a very low level, which is crucial in games where reflexes play an important role. With a high refresh rate of 120 Hz, the picture is exceptionally smooth, significantly enhancing the experience of fast-paced action games and sports productions. The television also supports G-Sync and FreeSync technologies, which further enhance gameplay smoothness and improve user comfort. An interesting addition is the 'Game Bar' – a special menu that provides quick access to all game-related settings, allowing easy adjustments of picture and parameters to suit user preferences without the need to interrupt gameplay.

Although the Samsung QN95D does not support Dolby Vision – which is quite obvious for Samsung televisions – it does offer the HGiG feature, which ensures appropriate picture quality in HDR games, in line with the creators' vision.
