TCL P7K / P79K vs Panasonic Z95B

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 quality of HDR on the Panasonic Z95B is among the absolute best. Thanks to the latest generation panel, referred to by the manufacturer as Primary RGB Tandem OLED, the television can achieve over 2000 nits of brightness in cinematic scenes. The effect is impressive and can amaze with the intensity of the light, providing a sense of connection with the screen that goes beyond previous experiences. Similar feelings accompanied us only during tests of the LG G5, Samsung S95F, or Philips OLED910. Of course, there are moments when the device's algorithms decide to limit luminance – this especially concerns full-screen bright sequences, such as the closing credits in the film The Meg. Even then, the Z95B maintains a level of around 1500 nits, which is still an incredibly impressive result. One can thus say that HDR in this model has reached masterful form. A significant step forward is also evident in colour reproduction. The new tandem OLED panel does not yet match the best QD-OLED screens in terms of full gamut coverage, but the gap between these solutions has significantly decreased. When watching films, the differences are subtle enough that under normal conditions they are hard to notice, and the colours remain vivid and saturated.

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 factory colour reproduction of the Filmmaker mode, my dear friends, is truly remarkable in the case of the Panasonic Z95B. I'm referring to our test sample, but the result was so good that it’s hard to believe. The only detail one might nitpick about is a slight lack of blue in the white balance, but apart from that, the television straight out of the box presented an image unlike anything we have ever seen in factory mode. Tests of the colour palette, Color Checker – everything indicated values below Delta 2. That’s a much lower result than the threshold of human eye perception, which means, quite simply, that the viewer has no chance of noticing any serious deviations. It looks as though Panasonic has actually calibrated this model at the factory stage. Of course, we cannot rule out the possibility that we received an exceptionally well-set sample, but the result is still impressive. We are very strict when it comes to evaluating factory calibration, and here our jaws simply dropped.

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 colour representation after calibration in the Z95B is a topic that is difficult to elaborate on, as there was simply not much to be done here. A slight adjustment of the white balance was sufficient to eliminate the lack of blue, and at this point, the picture reached an almost reference level. It must be admitted that we haven't had such a small range of work in a while. If any of you are particularly observant, you may notice minimal deviations in the EOTF curve, but this is rather related to the operation of the dynamic tone mapping function we mentioned earlier. In fact, it is not a flaw, but a characteristic of this solution, which deliberately alters the brightness characteristics depending on the scene. In summary, we are extremely impressed. The Panasonic Z95B is a television that looks great straight out of the box, and after calibration, it reaches a level where it is truly difficult for us to find anything to improve.

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.

Let’s start with what works well. The upscaling on the Z95B is at a very high level – the picture in lower resolutions is clear and sharp, and the only minor drawbacks are subtle aliasing in certain areas of the image. It’s also important that the television does not crop the material in any way and maintains its proportions, which is not always an obvious fact even in 2025.

The situation with digital processing is less impressive. Features such as “gradation smoothing” or “block noise reduction” practically do not work – the material tested looked identical regardless of the settings. We might as well state that this feature simply does not exist. This is somewhat disappointing, especially since Panasonic heavily promotes its HCX Pro AI II processor, boasting the presence of artificial intelligence to enhance picture quality. Meanwhile, in such a basic area, the television does not provide a real effect and it appears weaker than one might expect from high-end equipment.

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.

The OLED matrix with a very high refresh rate already provides an extremely sharp image even in dynamic sports scenes, such as football or basketball matches, and the Z95B is no exception. It is also very important that the television is equipped with an proprietary motion smoothing system called “Intelligent Frame Creation”. Among the available sliders, the most important one is the one named “film smoothness”, as it allows you to adjust motion to your own preferences when watching 24-frame materials, i.e. films – from a more “frame-like” appearance to a smooth, almost theatrical effect. It is somewhat disappointing that Panasonic did not choose to overclock the latest OLED matrix to 165 Hz, as Samsung did with the S95F or LG with the G5, because we know that the panel is technically capable of it. On the other hand, this is mainly an advantage for PC gamers, so in everyday viewing, it is not a significant drawback since we are limited to 120Hz.

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.

The Panasonic Z95B is fully equipped for gaming. Two HDMI 2.1 ports with full bandwidth of 48 Gb/s guarantee support for everything you would expect from a modern screen. There is VRR frame synchronization, an automatic ALLM game mode, and full compatibility with HDR formats used in games. The television supports both Dolby Vision for Xbox and the popular HGiG, which has been implemented correctly in this case, so it actually works as it should.

Although the brand is mainly associated with home cinema and equipment for filmmakers, there is also room here for features for gamers. On board, there is a Game Bar (or rather Game Circles) – visually, it looks a bit unusual, but it serves its purpose and allows you to quickly check the most important picture parameters. The only thing that is actually missing for complete happiness is having four HDMI 2.1 ports instead of two. It's a minor detail, but in a television of this class, one could expect a full set.
