Samsung Neo QLED QN95D vs TCL P7K / P79K

The Samsung QN95D excels in HDR performance, achieving an impressive peak brightness of approximately 2000 nits. In tested movie scenes with fully lit screens, the television delivers an intense and realistic representation of HDR content, significantly enhancing the viewing experience. However, as with its handling of contrast, the dimming algorithm occasionally reveals limitations.

Despite the large number of Mini LED zones, the television doesn’t consistently provide extraordinary brightness. For instance, in scenes from "Life of Pi," featuring a bright moon against a dark background, and excerpts from "Sicario 2," showcasing intense light effects on dark backdrops, the QN95D underperforms. In such instances, the television mitigates halo effects by dimming the image to a level closer to SDR quality. While this ensures deep and uniform blacks, it comes at the cost of losing some detail in bright areas. This compromise is intended to preserve black quality but can detract from the image’s dynamism.

Despite these occasional shortcomings in the local dimming algorithm, the QN95D deserves commendation for its wide coverage of the DCI-P3 colour gamut. Thanks to the quantum dot coating, also known as QLED technology, the television produces vibrant and richly saturated colours, adding to its appeal for HDR content.

When evaluating the HDR effect, we must make it clear and without marketing embellishment: the P7K/P79K is not and was never meant to be a master in this field. The maximum peak brightness that this panel can generate is only around 300 nits. This is a borderline value, a sort of thin red line between what can be considered a barely satisfactory HDR signal and what is really 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 parts of the content rarely exceeded the threshold of 200-250 nits. Therefore, this is not a television that would allow content produced in a wide tonal range to truly shine, and we must openly acknowledge that.

Unfortunately, the issue of color reproduction is presented equally restrained. Although the manufacturer positions this model in 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 color gamut is only 86%. Compared to the market, this is at best an average result, as most devices that employ additional layers to expand the color spectrum easily achieve values at a minimum level of 90-92%.

The Samsung QN95D was evaluated for factory colour reproduction in Filmmaker mode, which provides the manufacturer’s optimised settings. While this mode delivers good performance, it is not without shortcomings. For HD content, notable colour deviations were observed, particularly in white balance, where a red tint dominated the chart. Improvements were noted with 4K HDR content; however, significant deficiencies in blue colour reproduction persist. This is evident in scenes such as those from Star Wars, where the main character appears in tones that are warmer than intended.

Regarding contrast, the gamma chart reveals an initial steep rise, demonstrating the television’s capability to emphasise brighter image areas effectively. However, the chart also shows a clear dip at the lower end, suggesting a potential loss of detail in darker tones. This gamma curve shape could impact the clarity of dark scenes, where details may appear overly blurred or obscured. Additionally, the brightness curve (EOTF) was mostly accurate, aside from an initial drop.

Despite these minor issues, the QN95D boasts impressive features and cutting-edge technology that solidify its position as one of the top televisions on the market. However, refinements in colour accuracy and contrast are needed to maximise its potential fully.

Every reliable image quality assessment must begin by selecting the most optimal factory mode. In the case of the tested model P7K/P79K, the choice was confidently made for the "Film" mode. It is this mode that presents an image closest to the creators' intentions, avoiding both the exaggerated brightness of 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 is not free from a few stumbles. The most noticeable flaw turned out to be an imperfectly adjusted white balance. A slight dominance of the blue component gives the image a subtly cool, chilly character, thus deviating from the exemplary neutrality that the director wanted to show us. The television performs much better in reproducing the grayscale in a standard dynamic range – the gamma curve is executed almost perfectly. A minor reservation can only be made for 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 TCL's software, however, was the interpretation of the HDR signal, which is illustrated by the EOTF curve. The television follows its own, rather free path here – the darkest details are disproportionately brightened, followed by a noticeable slowdown in brightness increase for midtones. Fortunately, most of these imperfections are software-related issues that can be eliminated. With this thought in mind, we proceeded to the professional calibration process.

After calibration, the Samsung QN95D delivers truly impressive results. The white balance is perfectly aligned, with error readings rarely exceeding 2, indicating faithful colour reproduction. Most samples from the Colour Checker test fall well within an acceptable error range, confirming the television's excellent performance in accurately displaying colours. Contrast has also improved significantly, and the gamma curve has become more stable, ensuring better visibility of details in both dark and bright scenes.

However, the EOTF (Electro-Optical Transfer Function) curve still shows a slight divergence in film tests. While the television performs well in most scenarios, some details in black may still be lost in extreme cases due to the aggressive dimming algorithm.

Despite these minor imperfections, the overall image quality remains outstanding. After calibration, the Samsung QN95D impresses with its visual performance, offering an exceptional experience that will satisfy anyone seeking a top-tier television.

The calibration process turned out to be a home run, especially in the context of standard dynamic range (SDR) content. We successfully managed to eliminate the TV's tendency to emphasize cool tones, restoring the whites to their natural neutrality. Furthermore, precise adjustments allowed us to correct a slight error in the gamma curve, so the darkest areas of the image regained their proper depth, without a trace of unnatural brightening. The effects are measurable and impressive – in the ColorChecker test, the vast majority of color reproduction errors fell below the perceptual threshold, achieving a deltaE value below 2. This is a result that would not shame much more expensive constructions. Unfortunately, in the case of HDR content, we hit a wall in the form of the inherent limitations of the panel itself. And although we managed to bring the colors in line, the software's specifics mean that the TV still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. In summary, calibration brings tremendous added value, but one must be aware that it cannot overcome certain physical barriers. A slight boost in black levels, resulting from the lack of local dimming, and limited peak brightness mean that HDR content will not always be able to showcase its full potential. This is simply not the main task of this display; its true strength, especially after professional tuning, lies in the viewing of SDR materials.

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

Despite this, the television performs well in terms of image scaling, eliminating larger jagged edges. In a scene where branches are visible, they are not overly artificially sharpened, which allows for a natural look, and the model does not have an artificial outline. Overall, even in more challenging conditions, the footage is presented satisfactorily on the Samsung QN95D. The only downside when watching HD/SD content (such as regular terrestrial television) is the fact that the image is slightly cropped - 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 digital processing and content scaling. It should be noted right away that we are not talking about the level known from flagship designs; nevertheless, in the price segment represented by the P7K/P79K, the results achieved are more than solid. The feature that smooths tonal transitions performs particularly well, effectively eliminating posterization, which are the characteristic bands often visible in materials with higher compression, such as from the YouTube service. The algorithm can elegantly remove unwanted gradients, which ultimately looks really good. The television also competently handles upscaling, which is the task of raising low-resolution materials to 4K standard. The output image, although it may seem a bit too sharp out of the box, fortunately, is not a problem. The software allows for easy adjustment of this parameter using a sharpness slider, so the final appearance can be easily tailored to personal preferences.

The Samsung QN95D panel excels in motion blur and fluidity, offering a 120 Hz refresh rate along with features designed to reduce blur and judder. This allows users to adjust the picture settings to their liking, whether for movie watching or dynamic sports broadcasts. The television provides a 10-point scale for adjusting image smoothness, ranging from a frame-like appearance reminiscent of traditional film to a smoother, more cinematic effect, which is especially beneficial for sports broadcasts. This level of customization enhances the viewing experience across various types of content.

The issue of fluidity and sharpness of the image in motion is inextricably linked to the fundamental parameter of the panel, and in the case of the TCL P7K/P79K, we are dealing with a panel that has a native refresh rate of 60 Hz. This specification already defines its capabilities and makes it difficult to unequivocally recommend it to enthusiasts of dynamic sports broadcasts. During rapid camera movements, the image loses sharpness, and the panel itself also shows a slight tendency to blur, 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 materials recorded at 24 or 30 frames per second. Thanks to a dedicated slider, the user can independently decide on the final character of the motion – from a fully cinematic, slightly juddery image to achieving a very smooth, almost theatrical effect. It is a simple yet effective tool that allows users to tailor the viewing experience to their own preferences.

The Samsung QN95D offers several features that gamers will appreciate. First, the TV supports a variable refresh rate (VRR), which eliminates screen tearing and provides smoother gameplay, especially in dynamic scenes. It also includes an automatic game mode (ALLM) that switches the TV to low latency mode when a connected console or computer is detected, resulting in more responsive controls.

Additionally, the QN95D has a game mode that reduces input lag to an impressively low level, which is vital for games where quick reflexes matter. With a high refresh rate of 120 Hz, the image remains exceptionally smooth, enhancing the experience of fast-paced action games and sports. The TV also supports G-Sync and FreeSync technologies, further improving gameplay and user comfort. An interesting addition is the 'Game Bar' – a special menu that provides easy access to all gaming-related settings, allowing users to quickly adjust the image and other parameters without interrupting gameplay.

While the Samsung QN95D does not support Dolby Vision, which is typical for Samsung models, it does feature HGiG functionality, ensuring that HDR games are displayed with the appropriate image quality in line with the creators' intentions.

Although on paper the native 4K@60Hz matrix might suggest that the TCL P7K/P79K is not a TV tailored for gamers, the reality turns out to be 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 completed 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 TV easily supports high refresh rate signals of 120 Hz, but at lower resolutions – 1080p and 1440p. This is fantastic news for console owners who know full 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 avid tournament gamers, it offers a package of options for the casual or occasional console user that is hard to find among many competitors at this price point.
