Samsung Neo QLED QN95D vs TCL P7K / P79K

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.

When turning to the assessment of HDR performance, we must be clear and without marketing embellishments: the P7K/P79K is not, and was never intended to be, a master in this field. The maximum peak brightness that this panel can generate hovers around a mere 300 nits. This represents a threshold, a kind of thin red line between what can be considered a barely satisfactory HDR signal and what is, in fact, not much different from standard dynamic range (SDR), unfortunately leaning towards the latter. Synthetic tests found brutal confirmation in reality – our measurements taken during movie screenings showed that luminance in key bright portions of the scenes rarely exceeded the ceiling of 200-250 nits. Thus, this is not a television that would allow content realised in a wide tonal range to spread its wings, and this must be openly admitted.

Unfortunately, the issue of colour reproduction is presented with equal restraint. Although the manufacturer positions this model within the "QLED" family, thanks to the use of a PFS LED filter, the results do not match the heightened expectations. The coverage of the wide DCI-P3 colour gamut reaches only 86%. In the context of the market, this is at best an average result, as most devices that employ additional layers to expand the colour spectrum easily achieve values at a minimum level of 90-92%.

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.

Every accurate assessment of image quality must begin with selection of the most optimal factory mode. In the case of the tested model P7K/P79K, the choice was made without hesitation for the "Film" mode. It is this mode that presents an image closest to the intentions of the creators, avoiding both the exaggerated brightness of the dynamic mode and the excessive dimming known from eco settings. And it must be admitted that, for a device in this price range, the factory calibration is surprisingly decent, although it has not escaped a few missteps. The most noticeable flaw turned out to be the not completely correctly set white balance. A slight dominance of the blue component gives the image a subtly cool, cold character, thus deviating from the exemplary neutrality that the director wanted to show us. The television performs much better in reproducing the greyscale in the standard dynamic range – the gamma curve is nearly exemplary. The only minor reservation could be made regarding the darkest parts of the image, where a slight deviation from the norm causes a loss of some detail in the shadows. The most serious challenge for the TCL software, however, was interpreting the HDR signal, as illustrated by the course of the EOTF curve. The television follows its own, quite free path here – the darkest details are disproportionately brightened, after which there is a noticeable slowdown in the increase of brightness for midtones. Fortunately, most of these imperfections are software-related issues that can be eliminated. With this thought in mind, we began the process of professional calibration.

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.

The calibration process turned out to be spot on, particularly in the context of standard dynamic range (SDR) content. We successfully mitigated the television's tendency to emphasize cool tones, restoring the whiteness to its natural neutrality. Moreover, precise adjustments allowed us to correct a slight error in the gamma curve, ensuring that the darkest parts of the image regained their proper depth, without any trace of unnatural brightness. The effects are measurable and impressive – in the ColorChecker test, the overwhelming majority of colour reproduction errors fell below the perceptual threshold, achieving a deltaE value of under 2. This is a result that pricier models would not be ashamed of. Unfortunately, when it comes to HDR content, we encounter a barrier in the form of the inherent limitations of the panel itself. And although we managed to bring the colours into line, the software's characteristics mean that the television still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. In summary, calibration adds immense value, but one must be aware that it cannot overcome certain physical barriers. The slightly elevated black level, due to the lack of local dimming, along with limited peak brightness, means that HDR content may not always be able to showcase its full potential. This is simply not the primary task of this display; its true strength, especially after professional tuning, lies in the viewing of SDR material.

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.

After a series of harsh evaluations, fortunately, the time comes for praise, and this is due to the TCL AiPQ image processor for its work in the field of digital processing and content scaling. It should be noted right away that we are not talking about the level known from flagship designs; however, in the price segment represented by the P7K/P79K, the results achieved are more than solid. The feature for smoothing tonal transitions performs particularly well, effectively eliminating posterisation, which are the characteristic bands often visible in highly compressed materials, for example, from the ChooseTV service. The algorithm adeptly removes unwanted gradients, which ultimately looks really good. The television also handles upscaling competently, which is the task of elevating low-resolution materials to 4K standard. The resulting image, although it may initially seem a bit too sharp, fortunately, is not a problem. The software allows for free adjustment of this parameter using a sharpness slider, making it easy to customise the final appearance to personal preferences.

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 issue of fluidity and sharpness of the image in motion is inextricably linked to a fundamental parameter of the matrix, and in the case of the TCL P7K/P79K, we are dealing with a panel with a native refresh rate of 60 Hz. This specification defines its capabilities from the outset and makes it difficult to unequivocally recommend it to enthusiasts of dynamic sports broadcasts. During fast camera movements, the image loses sharpness, and the panel also shows a slight tendency to smearing, which may be noticeable to more sensitive viewers. Fortunately, not everything in this aspect has been left to chance. The manufacturer has implemented a simple motion smoothing system, which is primarily used in film material recorded at 24 or 30 frames per second. Thanks to a dedicated slider, users can decide for themselves the final character of the motion – from maintaining a fully cinematic, slightly juddery image to achieving a very smooth, almost theatrical effect. It is a simple but effective tool that allows users to tailor the viewing experience to their own preferences.

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.

Although on paper the native 4K@60Hz panel might suggest that the TCL P7K/P79K is not a television tailored for gamers, the reality is surprisingly different. On the contrary, the manufacturer has ensured a rich package of features that make it a very friendly companion for next-generation consoles. Onboard, we find key technologies such as ALLM, which provides automatic switching to low latency mode, and VRR, or variable refresh rate, which eliminates screen tearing. The list is complemented by support for Dolby Vision Gaming and a simple yet functional Game Bar. However, the real and extremely pleasant surprise is something else. It turns out that the television easily supports a high refresh rate signal of 120 Hz but at lower resolutions – 1080p and 1440p. This is fantastic news for console owners, who know well how rarely games run in native 4K at a full 120 frames per second. The ability to choose between higher resolution and doubled smoothness is therefore an extremely sensible compromise.

In summary, although the P7K/P79K may not be the target screen for the most passionate tournament players, for the casual or occasional console user, it offers a package of options that is hard to find among many competitors at this price.
