TCL C9K vs Panasonic W95B

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

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.

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 veers towards red, which may cause a subtle warming of the image, and the gamma curve is slightly elevated, making the screen appear a bit brighter. It is good that the manufacturer included this mode – even in factory configuration, it provides a reasonably natural appearance for films. However, knowing how susceptible Panasonic televisions are to calibration, we decided to see how much the image could be improved after professional tuning.

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.

After professional calibration, the Panasonic W95B shows what it is truly capable of. Colour errors have mostly dropped below values of 2–3, making them practically invisible to the human eye. It was also possible to correct the excess red in the white balance, which has resulted in the image no longer having a slight pink tint, and details in dark areas are no longer lost due to excessive dimming in the gamma. In HDR content, the improvement is also noticeable – colour saturation is now more stable and does not shift so markedly towards blue as it did before. This is truly an excellent television for watching films and series in the highest possible quality. While we know that Mini LED screens are not always perfect for this, the W95B is a perfect example that with proper fine-tuning, an effect close to OLEDs can be achieved.

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.

In terms of image processing, the Panasonic W95B performs excellently. The proprietary processor responsible for digital image processing effectively upscales lower resolution content to 4K, preserving a great deal of detail and a natural appearance of contours. The final effect is impressive – the upscaling here is at a truly high level, and Full HD content can look surprisingly good. The way the television smooths tonal transitions in low-quality materials is also noteworthy. The algorithm does not operate as aggressively as in some competing models, but as a result, it does not cause a loss of detail or blur film grain.

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.

The 144 Hz panel used in the Panasonic W95B offers excellent fluidity, although in practice, due to the appearance of television content or the limitations of new generation consoles, it is worth observing its performance at a refresh rate of 120 Hz. In this mode, the television performs superbly – despite being a VA panel, which is not known for the fastest pixel response times, motion blur here is minimal and difficult to detect with the naked eye.

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.

Aside from the previously mentioned drawback related to the VRR mode, in which local dimming does not work, the Panasonic W95B is a true gaming monster. The television offers practically everything that gamers can expect – perhaps except for four HDMI 2.1 ports, as there are only two available. Onboard, we find an auto low latency mode (ALLM), properly implemented HDR modes for gamers, including HGiG, as well as support for Dolby Vision in games. It is all complemented by an interestingly designed Game Bar, presented in the form of circles. While it may not be the most visually attractive, it serves its purpose – allowing quick access to key game parameters and adjusting settings without entering the system menu.
