TCL C9K vs Panasonic W95B

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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
