TCL P7K / P79K vs Panasonic Z95B

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 quality of HDR in the Panasonic Z95B belongs to the absolute elite. Thanks to the latest generation panel, named by the manufacturer Primary RGB Tandem OLED, the television can achieve over 2000 nits of brightness in movie scenes. The effect is impressive and can amaze with the intensity of light, giving a sense of contact with the screen that goes beyond previous experiences. Similar sensations 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 applies to full-screen bright sequences, such as the closing credits in the movie The Meg. Even then, the Z95B maintains a level of around 1500 nits, which is still a result that makes a huge impression. One can say that HDR in this model has been brought to a masterful form. A significant step forward is also visible in the reproduction of the color palette. 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 narrowed. When watching movies, the differences are subtle enough that it's hard to notice them under normal conditions, and the colors remain vivid and saturated.

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.

The factory color reproduction in Filmmaker mode, my friends, is a true phenomenon in the case of the Panasonic Z95B. I'm talking about our test unit, but the result was so good that it's hard to believe. The only detail to nitpick is a slight lack of blue in the white balance, but other than that, the television, right out of the box, displayed an image like we've never seen in factory mode. Color palette tests, Color Checker – everything pointed to values below Delta 2. This is a much lower result than the threshold of human eye perception, which means, quite frankly, that the viewer stands no chance of noticing serious deviations. It looks as if Panasonic really calibrated this model at the factory stage. Of course, we cannot rule out that we got an exceptionally well-set unit, but the result is still impressive. We are very strict in our assessments of factory calibration, and here our jaws simply dropped.

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 color reproduction after calibration in the Z95B is a topic that is difficult to elaborate on for long because there simply wasn't much to be done here. A slight adjustment of the white balance was enough to eliminate the lack of blue, and at that moment the picture jumped to an almost reference level. I must admit that we haven't had such a small scope of work in a long time. If any of you are particularly observant, you might notice minimal deviations in the EOTF curve, but this is more related to the operation of the dynamic tone mapping function that we mentioned earlier. Really, this is not a flaw, but rather a feature of this solution, which intentionally changes the brightness characteristic depending on the scene. In summary, we are extremely impressed. The Panasonic Z95B is a television that already looks great right out of the box, and after calibration, it reaches a level where it is really hard 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 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.

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

The situation is worse when it comes to digital processing. Features such as "gradation smoothing" or "block noise reduction" practically do not work – the tested material looked identical regardless of the settings. We might as well point out that this function simply doesn't exist. This is somewhat disappointing, especially since Panasonic strongly promotes its HCX Pro AI II processor, boasting of the presence of artificial intelligence that improves picture quality. Meanwhile, in such a basic matter, the television does not deliver a real effect and looks worse than one might expect from top-of-the-line equipment.

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 OLED matrix with a very high refresh rate already provides an extremely sharp image even in dynamic sports scenes, such as soccer or basketball matches, and the Z95B is no exception. It's also very important that the television is equipped with the proprietary image smoothing system "Intelligent Frame Creation." Among the available sliders, the most important one turns out to be the one named "film smoothness," because it allows adjusting the motion to personal preferences when watching 24-frame material, that is, movies – from a more "frame-like" appearance to a smooth, almost theatrical effect. It's a bit of a shame that Panasonic did not choose to push the latest OLED matrix to 165 Hz, as Samsung did with the S95F or LG with the G5, because we know the panel is technically capable of it. On the other hand, this is mainly an advantage for PC gamers, so for everyday viewing this is not a significant drawback as we are limited to 120Hz.

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.

The Panasonic Z95B is completely equipped for gaming. Two HDMI 2.1 ports with full bandwidth of 48 Gb/s guarantee support for everything you can expect from a modern screen. There is VRR frame synchronization, an automatic game mode (ALLM), and full compatibility with HDR formats used in games. The TV 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 a place here for conveniences for gamers. It comes with Game Bar (or rather Game Circles) – visually it looks a bit unusual, but it does its job and allows you to quickly check the most important image parameters. What it really lacks for complete happiness is actually just four HDMI 2.1 ports instead of two. It's a minor issue, but one would expect a full set in a TV of this class.
