Panasonic Z95A vs TCL C9K

Panasonic Z95A showcases class when it comes to HDR performance. In luminance tests, it achieves a level of 1800 nits, which has a real impact on movie watching. Scenes from Life of Pi or Gemini Man look fantastic – the television effortlessly renders details and intensity of bright spots, impressing with its power. In more demanding moments, like the final scene from The Meg, one can see how bright light floods the screen. In such moments, brightness drops, which is typical for organic matrices. Nevertheless, a result around 1000 nits can still be considered excellent, still providing very good image quality. Additionally, the television offers excellent coverage of wide colour palettes – as much as 98.6% for DCI-P3 and 74.5% for BT.2020. Thanks to this, colours are not only vivid but also deeply saturated, allowing for a full appreciation of the richness of details, especially in HDR scenes. Such coverage makes the hues look more realistic, and the HDR effect gains in intensity and accuracy. All this impressive HDR effect is thanks to MLA technology, which enables achieving such high luminance and excellent image detail. Because of this, the Panasonic Z95A offers HDR at a level that truly makes a difference.

As we mentioned with black and contrast – the C9K makes a huge impression in synthetic tests. Our measurements showed that on a screen 10% filled with white, the television is capable of squeezing out... 4000 nits of brightness! It sounds cosmic, but – and here unfortunately the pattern repeats – the numbers say one thing, and practice another. In real film scenes, the situation looks different. In the best case, when the light effects occupy a large part of the image and the local dimming algorithm doesn't have to think too hard about what to do with thousands of zones – the result is really quite good. At that point, the C9K can reach about 1500 nits, which provides a pleasant, intense flash and can indeed make a positive impression.

The problem begins with smaller elements – such as stars in the sky, the moon, or individual reflections. That's when the proverbial cat comes out of the bag: the algorithms are not yet refined, and brightness drops even to 400–500 nits. This is a huge difference compared to the potential of 4000 nits that we saw in laboratory tests. Why does this happen? Most likely, the television tries to protect the black and minimise the halo effect around bright objects. Unfortunately, this comes at the cost of details – some of the intricate details simply disappear, and the scene loses its nature.

The best picture mode on the Panasonic Z95A is undoubtedly the Filmmaker mode. It offers quite a good image reproduction, but it is not free from certain issues that require improvement. Firstly, the white balance, for both 4K and HD content, tends to have a dominance of red and blue hues. This causes a slight pinkish tint to the image, particularly noticeable in bright, white scenes. Such deviations can be seen in the comparative photo below, which illustrates this issue well. The Colour Checker test also confirms these discrepancies, showing slight shifts in the dots towards the mentioned shades.

In terms of gamma brightness characteristics, it performs very well, with only minor problems when brightening small details. A greater challenge is posed by the EOTF curve, which is responsible for controlling brightness in 4K HDR content. Here, there is a slight boost in brightness above the reference value, which sometimes makes the image too bright, especially in more demanding scenes. Although the Filmmaker mode is definitely the best choice on the Z95A, these aspects require refinement to fully utilise the television's potential.

For colour tests, we once again reached for the Filmmaker mode – a new feature in TCL televisions for 2025. And although the direction itself is a step in the right direction, the execution leaves much to be desired. The white balance in SDR content turned out to be too warm – there was an excess of red. Conversely, in HDR, it swung in the opposite direction: the image became excessively blue. The Colour Checker test revealed quite a few colour inaccuracies that were noticeable to the naked eye. An even bigger problem turned out to be what we mentioned above – managing brightness. Regardless of whether we were watching SDR or HDR content, the image had a tendency to blow out the entire scene, giving it an unnatural, almost grotesque character. Therefore, it is hard to call this a 'director’s mode' – because the director surely has never seen such an image.

After calibration, Panasonic Z95A shows its full potential, offering an almost perfect picture. The television provides immense adjustment capabilities, which we have fully utilised. The white balance after calibration is positively perfect, and errors in SDR content at the level of 0.5 place it in an absolutely reference standard. The same is true for 4K HDR content – the screen tint has been completely eliminated, and the white balance is now exemplary.

The colour palette and Colour Checker test confirm the excellence of the calibration. Errors below 2 are a result that will satisfy both professional calibrators and enthusiasts of cinematic picture quality. Significant changes have also occurred in the brightness characteristic – the EOTF curve has been flattened, eliminating previous issues with excessive brightness. And a small gamma error has been reduced.

Before calibration, the picture was decent, but now it's an entirely different league. It's a real feast for the eyes, the quality of which is hard to compare to anything else. Panasonic Z95A, after fine-tuning the settings, becomes a true master of colour reproduction.

After calibration, we finally managed to tame the white balance – and it immediately translated into a more natural image. Colours finally started to look as they should, and the overall presentation was incomparably better than with the factory settings. In other words – it’s worth taking a moment to improve this, as the gain is really significant. The gamma responsible for managing brightness was also brought under control in SDR content, and the effect was more than satisfactory. Unfortunately, when we switched on the HDR material, the situation quickly became complicated. No matter how we set the local dimming, the television had a tendency to do what it pleased with the image – either overexposing the whole picture or dimming the darkest parts too much. Just like we saw in the scene from the film Billy Lynn. Colour-wise, the improvement after calibration makes a great impression, but managing brightness in HDR remains the Achilles' heel of the C9K and constitutes a technological limitation.

In the case of lower quality materials, the function "Gradation Smoothing" is responsible for smoothing tonal transitions. The best results are achieved with an intermediate setting – although they are not spectacular, the function works correctly and does not introduce unwanted effects into the image. It can be rated as average, but sufficient to improve the quality of tonal transitions.

As for digital processing, or upscaling, the image looks surprisingly good. It is vivid and pleasant to the eye, which makes lower quality content, such as standard television or YouTube, look quite decent. However, minor issues can be noted, such as "jagged" edges, for example, branches in the background. Nevertheless, this does not significantly affect the overall viewing experience, and the television handles these materials in an acceptable manner.

The digital image processing in TCL C9K is rather mediocre. The tone transition smoothing feature is supposedly present, but activating it hardly makes any difference – colour banding is still visible, and it can inadvertently highlight elements we would prefer to hide, such as textures of objects. Fortunately, it does not remove film grain, but that's scant consolation considering the effects are still poor. Thus, it's hard to recommend using this option.

On the other hand, image scaling performs significantly better. Lower quality materials look quite decent – characters and backgrounds are represented clearly, although of course, with sources like 576p, the limitations of the physics cannot be disguised. Sometimes, there's characteristic aliasing of objects, but that's due to the source itself, not the algorithm. A plus for the fact that there are no overscan issues – the image is neither artificially cropped nor enlarged.

Panasonic Z95A, thanks to its 144 Hz panel, offers excellent image fluidity. For films, there is an "Intelligent Frame Creation" feature that enhances fluidity and reduces motion blur. The user has two sliders at their disposal: "Motion Blur Reduction" – responsible for clearer and sharper details in rapidly moving scenes. "Film Smoothness" – adds fluidity by creating additional frames between the originals, making motion appear smoother and more natural with a "soap opera" effect.

Thanks to this, viewers can adjust the settings to their own preferences. Films and less dynamic material look smooth and natural, which should satisfy most users.

Similar to the C8K, the C9K is also a really fast television – both figuratively and literally. On board, we have a 4K panel with a refresh rate of 144 Hz, and at lower resolutions, the panel can even ramp up to 288 Hz. Such speed translates into practice – while watching sports or playing games, the picture looks very smooth and clear. Additionally, in films, we get an extra motion smoothing feature called Motion Clarity, which allows you to adjust the smoothness to your own preferences – from the cinematic "stuttering" of frames to nearly theatrical smoothness.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in terms of support for gamers. The television offers virtually everything one could expect from a device in this bracket. Support for ALLM (automatic low latency mode) and VRR (variable refresh rate) ensures smoothness and eliminates tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and additional support for resolutions other than 4K provides greater flexibility, which is a significant advantage for gamers using various configurations.

A unique and quite specific feature is the "Game Bar." Its ball-shaped interface stands out from the competition and allows for quick adjustments of key settings such as VRR, brightness level, or picture mode, without having to interrupt gameplay.

However, in this class of device, there is a minor disappointment – the Panasonic Z95A offers only two HDMI 2.1 ports, instead of four. This is definitely too few for a premium television, especially at a time when many people own more than one device requiring full HDMI 2.1 support, such as a next-gen console or an advanced computer. In this category, it's hard to accept this limitation, especially given the high aspirations of this model. Nevertheless, the television is an excellent choice for gamers, offering versatility and functionality at the highest level.

For gaming, the TCL C9K is a complete tool. Here we have two (out of four) HDMI 2.1 ports with full bandwidth of 48 Gbps, so all the key technologies work: VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). Additionally, the manufacturer has included a really intuitive Game Bar, which allows you to quickly check the most important parameters and adjust settings without rummaging through the menu. Also worth noting is TCL's policy – the television does not shy away from any HDR formats, even in game mode. Whether it's HGiG or Dolby Vision for the Xbox Series S/X console – everything works as it should, giving the player a wide range of freedom.
