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 distortions caused by the low brightness of the unit. Although the manufacturer has equipped its device with an HDR format offering dynamic metadata, HDR10+, which is what we're talking about, is very rarely used compared to Dolby Vision, which Samsung has not yet introduced in its televisions. It’s also worth mentioning that Samsung DU7192 offers only 82% coverage of the wide DCI-P3 colour gamut, which is another reason we shouldn't provide a signal in a wide dynamic range, as colour losses will be very noticeable. Samsung DU7192 delivers high-quality image that will satisfy most users.

Samsung QN95D handles HDR exceptionally well, achieving peak brightness around 2000 nits. In tested movie scenes where the screen is fully illuminated, the TV delivers intense and realistic HDR content reproduction, significantly enhancing the quality of visual experiences. However, similar to the contrast, the dimming algorithm can sometimes exhibit limitations. Despite a significant number of Mini LED zones, the TV won’t amaze users with incredible lighting. For example, in scenes from "Life of Pi," where a bright moon appears against a dark background, and in segments of "Sicario 2," featuring intense lighting effects on a dark backdrop, the TV shows very poor performance. During such moments, the TV attempts to reduce the halo effect by dimming the image to a level reminiscent of SDR quality. This results in deep and uniform blacks, but at the cost of losing some details in bright areas. It’s a compromise aimed at maintaining the best possible black quality, although it does make the image lose some of its dynamism. Despite some flaws in the local dimming algorithm's performance, this TV 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 flaws. Starting with the most basic graph, which is white balance, we can notice a significant dominance of red colour, both in SDR mode and HDR. Although in the latter there was also some green, which didn’t have a major impact on the overall perception. A graph 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 graph, if not more important, is gamma. This, which is supposed to control contrast in materials with a standard colour palette, was quite good in factory mode with one "but" regarding the beginning. In the darkest scenes, it was significantly lowered, resulting in strong brightening, which left the film lacking contrast and suspense overall. As we mentioned, HDR materials regarding white balance remained at a similar level. The main change is the EOTF curve graph. At the very beginning, we can observe a bulge, which, just like in the case of gamma, strongly brightened the darkest scenes. However, after that, the graph significantly changed its characteristics and the measured result dived below the reference line, causing the film to lose even more dynamism.

In the category of factory colour reproduction, the Samsung QN95D television has been tested in Filmmaker mode, which offers the best settings from the manufacturer. However, it is not entirely free of flaws. For HD content, there is a significant colour discrepancy, particularly in the white balance, where the red colour clearly dominates the graph. The situation improves with 4K HDR content, but there are still significant drops in blue colour reproduction. These effects can be observed in a scene from the film "Star Wars," where the main character is rendered in overly warm tones.

In terms of contrast, the gamma graph shows a large initial spike, indicating that the television effectively highlights the brighter parts of the image. However, at the end of the graph, we notice a significant drop, which may mean that details may be lost in darker tones. This shape of the gamma curve can affect how users perceive dark scenes, where some details may become too blurred or too dark, causing the image to lose clarity. It's also worth noting the curve corresponding to brightness (EOTF), which is quite correct, except for the initial drop.

Although the Samsung QN95D boasts impressive specifications and advanced technologies to earn the title of one of the best televisions on the market, it requires some improvements in colour reproduction and contrast to fully realise its potential.

Samsung has equipped even its lowest-end TVs with advanced tools for carrying out 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 picture will still look significantly cleaner than it did before the calibration process. We managed to model the gamma in SDR materials very well, allowing the image to be as contrasty as the TV permits. The EOTF curve has also changed its face and doesn’t brighten or darken the image in such a drastic manner. However, it is worth mentioning that in the case of HDR materials, the deltaE errors are still very high, but this is due to the unit's insufficient brightness.

After calibration, the picture on the Samsung QN95D television achieves truly impressive results. The white balance is perfectly balanced, and error readings rarely exceed a value of 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 colours excellently. The contrast has also improved significantly, and the gamma curve is more stable, leading to better visibility of details in 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, in more extreme cases, details in black can still be lost - this is due to an aggressive dimming algorithm.

Nevertheless, these minor imperfections do not diminish the overall picture quality. After calibration, the Samsung QN95D delights with its visual quality, offering an exceptional experience that will certainly please anyone looking for a top-of-the-line television.

Let's return for a moment to the tonal transition smoothing function. We can set it in only two ways - off and auto. As you can easily guess, the first of these causes significant issues with gradation. However, if we set the second option, both movies and series will offer us smooth colour transitions. It is worth mentioning, though, that this function has its drawbacks. It heavily interferes with the director's intent, softens the film grain effect, and worse, often misinterprets small details, blurring them as well. Consequently, we consider that this function does not exist and do not recommend using it, as this is how the smoothness of tonal transitions was tested on the tested display.

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

The Samsung QN95D television handles tonal transitions well, even in lower-quality materials, thanks to the noise reduction feature, which acts like a gentle gradient. This feature is incredibly effective, smoothly rendering the image and eliminating unwanted noise while significantly improving the quality of the displayed content. However, as is often the case, excessive effectiveness can lead to unintended side effects. In some materials, this feature can also blur elements that should remain sharp, such as film grain.

Despite this, the television performs well in terms of image scaling, eliminating larger jaggedness in the picture. In a scene where branches are visible, they are not overly artificially sharpened, which allows 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 (like regular terrestrial television) is 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 implemented a motion smoothing system. Although it is quite limited in features compared to higher models, its very existence is a significant plus in the context of competition in a similar price range. The maximum refresh rate that we will give to the tested television is 60 Hz, which is entirely sufficient for films and series, although not when it comes to sports. In the motion smoothing menu, we find two functions responsible for improving smoothness. These are "Motion Blur Reduction" and "Clear Motion (LED)". We'll discuss the latter a bit later. Let's focus on the former, as it is quite mysterious. Unfortunately, despite its presence, we did not find any usefulness. At each of the settings, the picture looked the same, characterised by the typical judder known from materials recorded at 24 fps.

The panel Samsung DU7192 features an average response time. It's worth mentioning that due to this specific type of panel, it is better than VA panels in a similar price range. Therefore, it can be said that it won't be the worst in terms of watching sports.

The panel in Samsung QN95 performs very well in terms of motion blur and fluidity. With a refresh rate of 120 Hz and features that reduce blur and jitter, users can adjust the picture settings to their personal preferences, whether for watching films or dynamic sports broadcasts. Users have the ability to customise the motion smoothness on a 10-point scale – from a more frame-like appearance, reminiscent of traditional film, to a smooth, almost theatrical effect that works especially well in sports broadcasts.

The Samsung DU7192 television is equipped only with HDMI 2.0 ports, which isn’t surprising considering the device’s price and its consumer profile. Therefore, it’s also logical that we won’t achieve maximum quality on the latest generation consoles. That’s why it only features the most basic options for gamers, namely ALLM. It’s a pity the manufacturer didn’t implement at least a GameBar, as this is now standard, even in lower-end TVs, and could offer significant conveniences in terms of quickly changing settings.

Samsung QN95D offers a fair bit of features that gamers will appreciate. First and foremost, the television supports Variable Refresh Rate (VRR), which allows for smoother gameplay by eliminating screen tearing issues, especially during dynamic scenes. There's also the Auto Low Latency Mode (ALLM), which automatically switches the TV to low latency mode when it detects a connected console or computer, providing more responsive control.

Additionally, the QN95D Samsung has a gaming 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 image is exceptionally smooth, significantly impacting the experience of dynamic 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 adjustment of the image and parameters to the user's preferences without the need to pause the gameplay.

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