TCL C9K vs Panasonic W95B

As we mentioned with black 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 is capable of squeezing out… 4000 nits of brightness! It sounds astronomical, but – and here, unfortunately, the pattern repeats – the numbers say one thing, and practice says another. In real movie scenes, the situation looks different. At best, when the light effects occupy a large part of the image and the local dimming algorithm does not have to think too hard about what to do with thousands of zones – the effect is really good. At that point, the C9K can reach around 1500 nits, which provides a pleasant, intense flash and can indeed make a positive impression.

The problem starts with smaller elements – such as stars in the sky, the moon, or single reflections. That’s when the proverbial cat comes out of the bag: the algorithms are not yet refined, and brightness drops to even 400–500 nits. That’s a huge difference compared to the potential 4000 nits we saw in laboratory tests. Why does this happen? Most likely, the television is trying to protect the blacks in this way and minimize the halo effect around bright objects. Unfortunately, this comes at the cost of details – 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 distant moon or helicopter lights in a scene from Sicario 2 – the TV does not impress. In such situations, brightness drops to around 200 nits, making the HDR effect much less visible. This happens because Panasonic prioritizes maintaining deep black levels without lighting up the background – for many users, this shouldn't be a cause for concern. However, it's important to remember that in these moments, the image starts to resemble SDR content. The coverage of the color palette also deserves praise, as it reaches about 93% of the DCI-P3 color space thanks to the use of the PFS filter (also known from QLED technology). As a result, most movies look very good in terms of saturation and colors, maintaining a cinematic quality of the image.

For color tests, as always, we reached for the Filmmaker mode – a new feature in TCL TVs for 2025. And while 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. On the other hand, in HDR, it went in the opposite direction: the image became excessively blue. The Colour Checker test revealed quite a few color errors 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 blow out the entire scene, giving it an unnatural, even grotesque character. It's hard to call this a "director-created" mode – because the director has certainly never seen such an image.

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

After calibration, we finally managed to tame the white balance – and it immediately translated into a more natural image. Colors finally started to look the way they should, and the overall presentation was incomparably better than in the factory settings. In other words – it’s worth taking a moment to improve this, as the gain is truly significant. The gamma responsible for managing brightness was also brought into order in SDR content, and the effect was more than satisfying. 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 dimmed the darkest parts too much. Exactly as we saw in the scene from the movie Billy Lynn. So, the color improvement after calibration makes a great impression, but brightness management in HDR remains the Achilles' heel of C9K and presents a certain technological limitation.

After professional calibration, the Panasonic W95B shows what it is really capable of. Color errors have mostly dropped below 2–3, making them practically invisible to the human eye. The excess red in the white balance has also been corrected, which has eliminated the slight pink tint, and details in dark areas no longer get lost due to overly strong dimming in the gamma. Improvements are also noticeable in HDR content – color saturation is now more stable and does not veer towards blue as clearly as before. It is truly a great television for watching movies and series in the highest possible quality. Although we know that Mini LED screens are not always perfectly suited for this, the W95B is an excellent example that with proper refinement, an OLED-like effect can be achieved.

Digital image processing in TCL C9K is quite mediocre. The tonal smoothing feature seems to be present, but turning it on practically changes nothing – color bands are still visible, and it can unintentionally highlight elements we would prefer to hide, such as textures of objects. Fortunately, it doesn’t remove film grain, but that’s small comfort since the effects are still poor. Therefore, it's hard to recommend using this option.

On the other hand, image scaling performs much better. Lower quality materials look quite decent – characters and backgrounds are presented clearly, although, of course, with sources at 576p, physics cannot be fooled. Sometimes, characteristic aliasing on objects appears, but that’s the fault of the source itself, not the algorithm. A plus for not having issues with overscan – the image is not artificially cropped or 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 amount of detail and a natural appearance of contours. The final effect is impressive – the upscaling 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 worth noting. The algorithm does not operate as aggressively as in some competing models, but as a result, it does not cause loss of detail or blurring of film grain.

Like the C8K, the C9K is also a really fast television – both figuratively and literally. It features a 4K panel with a refresh rate of 144 Hz, and at lower resolutions, the display can even ramp up to 288 Hz. This speed translates into practice – when watching sports or playing games, the image looks very smooth and clear. Additionally, in films, we get an extra motion smoother called Motion Clarity, which allows us to adjust the fluidity to our own preferences – from the cinematic "judder" frame to almost theatrical smoothness.

The 144 Hz panel used in the Panasonic W95B offers excellent smoothness, although in practice, considering how television content looks or the values to which next-generation consoles are limited, it's worth looking at its behavior when refreshing at 120 Hz. In this mode, the TV performs wonderfully – despite it 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 key technologies work: VRR (variable refresh rate) and ALLM (automatic low latency mode). Additionally, the manufacturer added a really intuitive Game Bar, which allows you to quickly preview the most important parameters and adjust settings without digging through the menu. Also, TCL's policy is a plus – the TV is not 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 wide 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 gamers can expect – except for four HDMI 2.1 ports, as there are only two available. On board, 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. This is complemented by an interestingly designed Game Bar, presented in the form of circles. While it may not be the most visually appealing, it serves its purpose – allowing a quick glance at key game parameters and adjusting settings without entering the system menu.
