TCL P7K / P79K vs Panasonic W95B

When it comes to assessing HDR performance, we need to be clear and straightforward without any marketing fluff: the P7K/P79K is not and never was meant to be a champion in this area. The maximum peak brightness that this panel can generate hovers around just 300 nits. This represents a threshold, a sort of thin red line between what can be considered barely satisfactory HDR signal and what is, in reality, only slightly better than standard dynamic range (SDR), unfortunately leaning towards the latter. Synthetic tests confirmed this harsh reality – our measurements taken during movie sessions showed that the luminance in key bright scenes rarely exceeded 200-250 nits. Therefore, this is not a TV that would allow content created in a wide tonal range to truly shine, and that must be openly acknowledged.

Unfortunately, the issue of colour reproduction is presented just as conservatively. Although the manufacturer positions this model within the "QLED" family, owing 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%. Compared to the market, this is at best an average result, since most devices that utilise additional layers to expand the colour spectrum easily achieve values at a minimum of 90-92%.

The Panasonic W95B is truly a bright screen, capable of achieving peak luminance levels of around 1400 nits. In brighter, well-lit movie scenes, this value translates into spectacular HDR effects that can leave a big impression. However, knowing our test setup, you probably see that in very demanding shots – such as the moon in the distance or the lights of a helicopter in a scene from Sicario 2 – the television doesn’t impress. In such situations, brightness drops to around 200 nits, making the HDR effect much less noticeable. This happens because Panasonic focuses on maintaining deep blacks, not illuminating the background – which shouldn’t be a concern for many users. However, it’s important to remember that in such moments, the picture starts to resemble SDR content. The coverage of the colour palette also deserves praise, as it reaches around 93% of the DCI-P3 space thanks to the use of the PFS filter (also known from QLED technology). This means that most films look very good in terms of saturation and colours, maintaining a cinematic quality to the image.

Every reliable assessment of image quality must start with selecting the most optimal, factory preset mode. In the case of the tested P7K/P79K model, the choice was made without hesitation for the "Film" mode. It is the mode that presents an image closest to the intentions of its 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 is not without a few stumbles. The most noticeable shortcoming turned out to be the not entirely correctly set white balance. A slight dominance of the blue component gives the image a subtly cool, frosty character, straying from the ideal neutrality that the director intended to show us. The television handles the reproduction of greyscale in the standard dynamic range much better – the gamma curve is almost exemplary. The only slight reservation can be made for the darkest parts of the image, where a delicate deviation from the norm causes a loss of some detail in the shadows. The most significant challenge, however, for the TCL software was interpreting the HDR signal, as 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 mid-tones. Fortunately, most of these imperfections are of a software nature, which can be eliminated. With that thought in mind, we proceeded to the process of professional calibration.

In Filmmaker mode, the Panasonic W95B offers an image with quite accurate colour reproduction, although it is not without minor imperfections. The white balance slightly leans towards red, which can cause a subtle warm tint to the image, and the gamma curve is slightly elevated, making the screen appear a bit brighter. It's good that the manufacturer has included this mode – even in its factory configuration, it provides a fairly natural look for films. However, knowing how susceptible Panasonic televisions are to calibration, we decided to check how much the image could be improved after professional tuning.

The calibration process turned out to be spot on, especially in the context of standard dynamic range (SDR) content. We successfully managed to eliminate the tendency of the television to showcase cool tones, restoring white to its natural neutrality. Moreover, the precise adjustment allowed us to correct a slight error in the gamma curve, enabling the darkest parts of the image to regain proper depth, without any signs of unnatural brightness. The results are measurable and impressive – in the ColorChecker test, the vast majority of colour reproduction errors fell below the perceptual threshold, achieving a deltaE value of below 2. This is a result that more expensive models would not be ashamed of. Unfortunately, in the case of HDR content, we encounter a wall in the form of the panel's structural limitations. And although we managed to bring the colours into line, the software's specifics mean that the television still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. To summarise, calibration adds tremendous value, but it is important to be aware that it won't overcome certain physical barriers. The slightly elevated blacks, resulting from the lack of local dimming, and limited peak brightness mean that HDR content won't 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 viewing SDR material.

After professional calibration, the Panasonic W95B shows what it’s really capable of. Colour errors have mostly dropped below values of 2–3, making them practically invisible to the human eye. The excess red in the white balance has also been corrected, which means the image is no longer slightly tinted pink, and details in dark areas no longer get lost due to excessive dimming in the gamma. The improvement in HDR content is also noticeable – colour saturation is now more stable and doesn’t lean towards blue as distinctly as it did before. It’s truly a fantastic television for watching movies and series in the highest possible quality. While we know that Mini LED screens are not always perfectly suited for this, the W95B is a prime example that with proper tuning, a result close to OLEDs can be achieved.

After a series of harsh evaluations, thankfully, it’s time for some praise, and this is deserved by 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 models; nonetheless, in the price segment represented by the P7K/P79K, the results achieved are more than solid. The function that smooths tonal transitions performs particularly well, effectively eliminating posterization, which are the characteristic bands often visible in materials with higher compression, for instance, from choose.tv. The algorithm can elegantly remove unwanted gradients, which ultimately looks really good. The television also handles upscaling competently, which means the task of raising low-resolution materials to 4K standard. The resulting image, although it may seem a bit too sharp out of the box, is fortunately not a problem. The software allows for free adjustment of this parameter using a sharpness slider, allowing the final appearance to be easily tailored to personal preferences.

In terms of image processing, the Panasonic W95B performs exceptionally well. The proprietary processor responsible for digital image processing effectively upscales lower resolution content to 4K, maintaining a high level of detail and a natural look to contours. The end result is impressive – the upscaling is truly top-notch, and Full HD content can look surprisingly good. Also noteworthy is how the TV smooths tonal transitions in low-quality materials. The algorithm doesn’t operate as aggressively as in some competing models, which helps avoid the loss of detail or the blurring of film grain.

The issue of fluidity and sharpness of motion image 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 at the outset defines its capabilities and makes it hard to unequivocally recommend it to enthusiasts of dynamic sports broadcasts. During quick camera movements, the image loses sharpness, and the panel also shows a slight tendency to smudge, 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 decide on the final nature of the motion – from maintaining a fully cinematic, slightly jerky image, to achieving a very smooth, almost theatrical effect. It is a simple yet effective tool that allows one to adjust the viewing experience to their own preferences.

The 144 Hz panel used in the Panasonic W95B offers excellent smoothness, although in practice, given how television content looks or how new-generation consoles are limited, it’s worth looking at its performance when refreshing at 120 Hz. In this mode, the television performs exceptionally well – despite being a VA panel, which is not known for the fastest pixel response times, motion blur is minimal and difficult to detect with the naked eye.

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 set 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 rounded off with 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 effortlessly supports a high refresh rate signal of 120Hz, but at lower resolutions – 1080p and 1440p. This is fantastic news for console owners, who know how rarely games run in native 4K at a full 120 frames per second. The option to choose between higher resolution and doubled smoothness is therefore an incredibly sensible compromise.

In summary, while the P7K/P79K may not be the target screen for the most passionate, tournament gamers, it offers a package of options for casual or occasional console users that is hard to find among many competitors at this price point.

Aside from the previously mentioned issue related to VRR mode, where local dimming does not work, the Panasonic W95B is a true gaming beast. The TV offers practically everything that gamers could expect – perhaps apart from four HDMI 2.1 ports, as there are only two available. On board, we find automatic low latency mode (ALLM), correctly implemented HDR modes for gamers, including HGiG, as well as support for Dolby Vision in games. The whole package is complemented by an interestingly designed Game Bar, presented in the form of circles. It may not be the most visually attractive, but it fulfills its purpose – allowing quick access to key game parameters and adjusting settings without diving into the system menu.
