TCL P7K / P79K vs SAMSUNG S95F (TANDEM OLED 83")

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%.

The Samsung S95F in the 83-inch variant with a Tandem OLED panel also manages to enchant with HDR effects. In test film scenes, such as "Life of Pi" or "Sicario 2", where smaller light points dominate – stars in the night sky, the glow of the moon or headlights – the television effortlessly achieves brightness values exceeding 2000 nits. This is a result that not long ago seemed unattainable for OLEDs and positions this model alongside the best Mini-LED constructions.

The limitations of organic panels only reveal themselves in full-screen scenes filled entirely with white. In the case of this model, for instance in the final scene from the film The Meg, brightness drops to around 1000 nits – a bit lower than in the smaller QD-OLED variants, where the result hovered around 1400 nits. Nevertheless, we are still talking about a remarkable result, unprecedented in OLED televisions of this size. The colour reproduction is equally impressive. The new Tandem OLED panel virtually catches up with QD-OLED televisions, offering excellent coverage of a wide colour gamut. The results are slightly weaker than with QD-OLED, but in practice, they still provide an image whose intensity and naturalness of colours are hard to compare with any other television.

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.

The best picture mode straight out of the box is undoubtedly Filmmaker Mode. This is a mode that has been available in Samsung televisions for several years and is intended to reproduce the image as faithfully as possible to the creators' vision. In SDR material, it performs reasonably well, although not without faults. The image is slightly subdued, and the white balance tends to shift towards red and blue, resulting in a slight pinkish tint on the screen. The average colour errors hover around a value of ΔE 3–4, which is at the limit of what most people can discern with the naked eye.

Much more pronounced are the limitations when it comes to HDR content. Here, a slight excess of blue in the white balance is not such a big problem – the real obstacle is the way the television manages brightness. In many scenes, the image appeared as if it had been overexposed, and details in the blacks could completely disappear. The final effect did not reflect what the hardware of this class is capable of and led to significant colour errors. It's hard to understand why such a factory characteristic was chosen, as the HDR reception in this version was definitely not what it should have been.

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.

After calibration, the S95F shows what it is truly capable of. The white balance has been corrected and minor inaccuracies adjusted, resulting in an almost exemplary image for SDR content. The colour differences have dropped below the level that the human eye can perceive – looking at the screen gives a sense of complete naturalness and colour coherence.

In HDR, the improvement is equally noticeable. The TV performs much better with brightness, eliminating the issue of "blowing out" the entire frame. Bright scenes are more controlled, and blacks retain more detail, although there can still be a slight brightening of the image as a whole. However, this does not change the fact that after calibration, the S95F delivers an image that can comfortably be called one of the best on the market – regardless of whether we are watching movies in SDR or spectacular productions in HDR.

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.

In the Samsung S95F model, there is a noise reduction feature aimed at improving the smoothness of tonal transitions. Its operation can hardly be called ineffective – on the contrary, it can overly interfere with the image. Older films or materials of poorer quality, such as those from YouTube, acquire a soft, smoothed character thanks to it, reminiscent of a painting effect. The problem is that along with the noise, the natural film grain disappears, stripping the image of its cinematic character. Fortunately, the feature does not blur significant details, so its use is more a matter of taste. If someone prefers a slightly polished and smooth image, it is worth enabling, but in our opinion, the most sensible setting is “Standard”.

A better impression is left by the upscaling. The S95F efficiently enhances the quality of lower resolution content – even 576p video looks quite good, although minor artifacts in the form of blockiness can be noticed. Overall, the effect is very solid, although when compared to competitors – such as the Sony Bravia 8 (II) or LG G5 – it is noticeable that those models can extract a bit more from the image. However, it is worth remembering one inconvenience: with older films and photos, there is an overscan issue that causes a slight cutting off of the left edge of the image.

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.

In the case of the 83-inch S95F with a Tandem OLED panel, the fluidity of motion also makes a huge impression. The panel, with a native resolution of 4K, offers a refresh rate of 165 Hz, and this combined with organic technology makes games and sports look superb. Additionally, the manufacturer has added a film smoother and a motion blur reduction system, allowing each viewer to adjust the image to their own preferences – whether it's a more "frame-rate" cinematic effect or a smooth, almost theatrical spectacle.

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.

Low smearing and phenomenal motion fluidity, which are the hallmarks of OLED displays, are just the warm-up. The Samsung S95F has been designed with gamers in mind – and this is evident at every turn. Four HDMI 2.1 ports with a bandwidth of 40 Gb/s may sound like a compromise on paper, but in practice, neither consoles nor PCs will experience the slightest limitation here. On board, there is a full set of gaming features: Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), as well as a flawlessly implemented HGiG standard that allows you to enjoy HDR exactly as the creators intended. All of this is complemented by Game Bar – an intuitive command centre where you can check and adjust the most important settings in seconds.

Particular attention should also be paid to Game Motion Plus, Samsung's proprietary motion smoothing technology. It can add extra fluidity to animations, which can be a lifesaver in games running at 60 frames per second, where stability doesn't always hold up. Indeed, support for Dolby Vision in games is lacking, but it’s hard to consider this a serious flaw – the manufacturer compensates for this gap with other solutions. The S95F is one of the absolute favourites for the title of the best gaming television on today's market.
