Samsung Q60D / Q67D / Q68D vs TCL P7K / P79K

The Samsung Q60D television, regardless of the scene being tested, achieves brightness above 500 nits, which is above average for this class of devices. Such a level of brightness allows one to experience a taste of true home cinema, with clearly visible details in bright parts of the image and well-reproduced contrast dynamics, especially when watching content from streaming platforms or movies played from Blu-ray. As a result, film screenings gain greater depth and realism, particularly in well-lit scenes. Despite the use of quantum dot technology (QLED), the television does not achieve outstanding results in colour reproduction. The coverage of the DCI-P3 colour space is only 90%, which may be noticeable in more demanding scenes, where the richness and saturation of colours play a key role in image quality.

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%.

Samsung has been offering a "Filmmaker" mode in its televisions for several years, aimed at providing the most faithful picture settings straight from the factory, in accordance with the vision of filmmakers. This is certainly a significant step towards cinematic quality at home; however, it is worth noting that this mode is not without its problems.

For instance, the white balance in both SDR and HDR modes exhibits an excessive amount of red hue, causing the picture to appear too warm. As a result, the skin of actors and bright scenes may seem unnaturally pinkish. The Colour Checker test further confirms this issue – colour samples often shift towards red tones, deviating from the neutral colour reproduction that would be more desirable in a professional setting.

When it comes to contrast, there is a noticeable drop at the beginning of the gamma graph, where values below 2.4 drop all the way down to 2.1. Consequently, the image in darker scenes may appear less distinct, losing depth. In terms of HDR content, the EOTF curve (responsible for brightness reproduction) shows a strong spike at the beginning of the graph, which may lead to excessive brightness in the lighter parts of the image, disrupting the natural tonal balance.

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 professional calibration of the Samsung Q60D television in film mode, users can enjoy a significant improvement in image quality. Samsung televisions have always offered 2- and 20-point grey scale adjustments, as well as an advanced CMS (Color Management System), which allows for precise colour and shade adjustments. The white balance for both SDR and HDR has been free from strong spikes and tendencies for colours to shift to red hues, greatly enhancing the naturalness of the image. Although a few more significant errors can still be observed in HDR mode, the overall colour reproduction quality has been excellently improved. Regarding contrast, although drastic changes cannot be mentioned due to limitations in the television's technology, the improvement is noticeable. Thanks to calibration, details in dark scenes are more visible, and the differences between light and dark elements of the image have been enhanced. This makes the overall viewing experience more satisfying, allowing viewers to enjoy greater depth and realism in the displayed content.

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.

However, when it comes to processing and scaling lower quality materials, the television performs quite well. The image is rendered without overscan, which ensures full use of the available screen area. Additionally, the outlines of the model or the branches of the tree are not overly jagged, which translates to a satisfactory quality of the displayed content. Although noise reduction could be more effective, the overall results of processing lower quality materials are positive and meet expectations.

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.

Samsung Q60D is equipped with a 60 Hz panel and a film smoothness enhancement option known as "Motion Blur Reduction." This feature aims to minimise motion blur and enhance overall image smoothness, which will certainly appeal to users who are primarily looking for a television to watch films and series. Thanks to this technology, viewers can enjoy a more fluid visual experience, even in dynamic action scenes where details are crucial. However, it is worth noting that while "Motion Blur Reduction" improves the smoothness of images in films, for gaming, this panel may not be the best choice as it exhibits significant motion blur, which can be seen in the picture below.

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 Q60D is equipped with features such as ALLM (Auto Low Latency Mode), HGiG (HDR Gaming Interest Group) and Game Bar, which significantly enhance the gaming experience. However, the lack of HDMI 2.1 implementation limits capabilities, preventing the use of VRR (Variable Refresh Rate), which could further improve smoothness and picture quality. Overall, for casual gamers, this television should perform well in everyday use, providing satisfactory gaming experiences. However, if we are more demanding in terms of gaming, it is worth considering models with a higher refresh rate and HDMI 2.1, which will ensure full functionality and better support for the latest games. In such cases, investing in a more advanced television will yield significantly better results in terms of smoothness and picture quality, which is crucial for gaming enthusiasts.

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.
