Panasonic Z95A vs TCL C9K

Panasonic Z95A shows 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 reproduces details and the intensity of bright spots, making a strong impression with its power. In more demanding moments, like the final scene from The Meg, you can see how bright light floods the screen. In such moments, brightness drops, which is typical for organic panels. Nevertheless, a result around 1000 nits can still be considered excellent, still providing very good picture quality. Additionally, the television offers great coverage of wide colour gamuts – up to 98.6% for DCI-P3 and 74.5% for BT.2020. This means that colours are not only vibrant but also deeply saturated, allowing full appreciation of the richness of details, especially in HDR scenes. Such coverage makes colours look more realistic, and the HDR effect gains intensity and accuracy. All this impressive HDR effect is thanks to MLA technology, which enables such high luminance and excellent image detail. With it, the Panasonic Z95A offers HDR at a level that truly makes a difference.

As we mentioned regarding black levels and contrast – the C9K can make a huge impression in synthetic tests. Our measurements showed that on a screen 10% filled with white, the television can achieve... 4000 nits of brightness! It sounds out of this world, but – and here's where the pattern unfortunately repeats – the numbers say one thing, and the practical experience says another. In real movie scenes, the situation looks different. In the best-case scenario, when light effects occupy a large part of the image and the local dimming algorithm doesn't have to ponder too much about what to do with thousands of zones, the effect is really quite good. At that point, the C9K can hit around 1500 nits, which delivers a pleasant, intense burst and can indeed leave a positive impression.

The problem arises 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 to as low as 400–500 nits. That's a huge difference from the potential 4000 nits we saw in lab tests. Why does this happen? Most likely, the television is trying to protect the black levels in this way and minimize the halo effect around bright objects. Unfortunately, this comes at the expense of detail – some details simply vanish, and the scene loses its nature.

The best picture mode on the Panasonic Z95A is undoubtedly the Filmmaker mode. This mode offers quite good image reproduction, but it is not without certain flaws that need addressing. Primarily, the white balance, for both 4K and HD content, tends to be dominated by red and blue hues. This leads to a slight pink tint in the image, particularly noticeable in bright, white scenes. Such discrepancies can be seen in the comparative image below, which illustrates the issue well. The Colour Checker test also confirms these inaccuracies, showing slight shifts of dots towards the mentioned shades.

In terms of gamma brightness characteristics, it performs very well, with only minor issues when brightening small details. A greater challenge arises with 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 overly bright, especially in more demanding scenes. While the Filmmaker mode is definitely the best choice on the Z95A, these aspects require refinement to fully harness the television's potential.

For colour tests, we once again reached for the Filmmaker mode – a new feature in TCL televisions for 2025. While the direction is a step in the right way, the execution leaves a lot to be desired. The white balance in SDR content turned out to be too warm – there was an excess of red. On the other hand, 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 – brightness management. Regardless of whether we were watching SDR or HDR content, the image tended to wash out the entire scene, giving it an unnatural, almost grotesque character. Therefore, it’s hard to call this a "director's mode" – because no director has ever seen such an image.

After calibration, Panasonic Z95A showcases its full potential, delivering an almost perfect image. The television offers extensive adjustment capabilities, which we have fully utilised. The white balance post-calibration is absolutely flawless, and the errors in SDR content at 0.5 are at an exceptionally reference standard. The same goes 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 cinema-quality image enthusiasts. Significant changes have also occurred in the brightness characteristics – the EOTF curve has been aligned, eliminating previous issues with excessive brightness. Additionally, a small error in gamma has been reduced.

Before calibration, the image was acceptable, but now it's in a completely different league. It's a true feast for the eyes, and the quality is hard to compare to anything else. Once fine-tuned, the Panasonic Z95A 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 on 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 brightness management also managed to be brought into order in SDR content, and the effect was more than satisfactory. Unfortunately, when we turned on HDR materials, the situation quickly became complicated. No matter how we set the local dimming, the television had a tendency to do what it liked with the image – either it overexposed everything or darkened the darkest parts too much. Just like we saw in the scene from the movie Billy Lynn. Colour-wise, the improvement after calibration makes a great impression, but brightness management in HDR remains the Achilles' heel of the C9K and presents a certain technological limitation.

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

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

Digital image processing on the TCL C9K is rather average. The smooth tone transition feature seems to be present, but activating it practically changes nothing – colour bands are still visible, and it can unintentionally highlight elements we’d rather keep hidden, such as object textures. Fortunately, it doesn’t remove film grain, but that’s poor consolation given that the effects are still meagre. It’s therefore hard to recommend using this option.

On the other hand, image scaling presents itself much better. Lower quality materials look quite decent – characters and backgrounds are rendered clearly, although of course, with sources like 576p, the laws of physics cannot be fooled. Occasionally, there’s characteristic edge distortion of objects, but that’s the fault of the source itself, not the algorithm. A plus for not having issues with overscan – the image isn't artificially cropped or enlarged.

Panasonic Z95A, with a 144 Hz panel, offers excellent image smoothness. For movies, there is an "Intelligent Frame Creation" feature that allows for improved smoothness and reduction of blurring. Users have two sliders at their disposal: "Motion Blur Reduction" – responsible for clearer and sharper details in fast-moving scenes. "Film Smoothness" – adds smoothness by creating additional frames between the originals, making motion appear more fluid and natural with the effect of "soap opera"

As a result, viewers can adjust the settings to their own preferences. Movies and less dynamic content look smooth and natural, which should satisfy most users.

Similar to the C8K, the C9K is also a really fast TV – both figuratively and literally. It features 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 image looks very smooth and clear. Additionally, in movies, we get an extra motion smoother called Motion Clarity, which allows you to adjust the smoothness to your own preferences – from cinematic "judder" to almost theatrical smoothness.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in support for gamers. The television offers practically everything you can expect from a device in this range. Support for ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate) ensures smoothness and no tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and the additional support for resolutions other than 4K provides greater flexibility, which is a big plus for gamers using various configurations.

Also noteworthy is the unique and rather specific "Game Bar." Its bubble interface stands out from the competition and allows quick adjustment of key settings such as VRR, brightness level, or picture mode, without the need to interrupt gameplay.

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

From a gaming perspective, the TCL C9K is a complete tool. It features two (out of four) full bandwidth 48 Gbps HDMI 2.1 ports, 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 that allows you to quickly check the most important parameters and adjust settings without fumbling through menus. Also, TCL's policy is a plus – the TV isn’t afraid of 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 plenty of freedom.
