TCL C855 vs Panasonic W95B

TCL C855 delivers a highly varied HDR effect. On one hand, the television truly shines, while on the other, it resembles a lower model with FALD backlighting. Such a state of affairs is regularly observed with this brand, so it was not a surprise for us. The first and last scene, which has large light elements, looks phenomenal, "shining" with brightness levels of 1470 and 1820 nits respectively. Such effects will certainly make many people squint, while simultaneously feeling the extraordinary dynamism of the scene itself. You can truly feel as if you were inside the movie. The situation drastically changes when small or minor elements with high luminance surrounded by black appear on the screen. The TCL C855, to avoid the halo effect, significantly reduces brightness to a level of even 240 nits, which is a disappointing outcome, causing the film to not look like it was shot in HDR. The HDR effect in TCL C855 makes watching dynamic scenes more engaging, and the viewer can feel like they are part of the action. Even with smaller elements of high luminance, the television manages to maintain details without excessive dimming. Moreover, the TCL C855 test shows that the brightness of the image is adapted to scenes with a large amount of detail, increasing viewing comfort.

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.

The best factory mode for the TCL C855 is "Film," and it is on this mode that we conducted all our tests. However, like every mode predefined by the manufacturer, it had flaws that are worth correcting to achieve an image that is as close as possible to what the film producer intended. We will look at the colour characteristics in both SDR and HDR materials. Taking the former into account, we see a clear dominance of green in the white balance, which, as you might guess, gave an unpleasant greenish tint to the entire image. Examining a very important gamma chart, responsible for the contrast of the image, we see a significant deviation from the reference line marked at 2.4. From the left, we can observe a strong spike in the measured value, which at this point caused contrast exaggeration and blending of details into a dark blob. This state of affairs persisted for quite a while, up to 20% of the chart’s value, before then diving below the reference. This, in turn, meant that the image was brightened and contrast decreased significantly. The factory mode performed somewhat better in HDR materials, as the white balance looked quite good, except for the second half, where green again took over. Looking at the EOTF curve, which, unlike gamma, shows the rate of brightness increase, we see primarily two errors: the darkest scenes were too dark, and the brightest ones were overexposed. This, by the way, could be observed in the scene from the film "Pan" in the check paragraph for the TV's HDR.

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.

TCL, just like the vast majority of manufacturers, provides advanced calibration tools in its televisions. Here we find 2- and 20-point grey scale adjustments as well as an advanced colour management system. The results, as you can see, are very good and in SDR materials we have significantly approached the reference image. We eliminated both the green tint and the gamma issue, although there is still a slight "kink" at the very beginning. It went a bit worse with HDR materials, which the television ChooseTV C855 did not allow us to model properly. We only managed to slightly adjust the EOTF curve and significantly improve the colours themselves.

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.

Once again, we will look at the function of smoothing tonal transitions, but this time also image scaling. The latter is particularly important when watching materials of lower quality, such as some TV programs or older films. We will focus on the function responsible for tonal transitions. Interestingly, just like in the scenes in the previous test, it performed splendidly and smoothed out practically all the choppiness, but here it had problems. Using the menu responsible for the operation of this function, we found that none - not even the strongest - setting helped.

The image scaling in TCL C855 is characterised as one of the best we have had the opportunity to test so far. The image is sharp, but in a way that could be described as natural to our eye. Even small, fine branches do not have jagged contours, and there is no white halo around figures, which is characteristic of weaker scaling systems.

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.

The maximum refresh rate that we can set on TCL C855 is 144 Hz. Naturally, this is only possible when connecting the TCL C855 TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a high level of motion dynamics. For those who require high fluidity of image, the manufacturer has implemented a multi-level motion smoother. It has been divided into two separate sliders that adjust the sharpness of moving images (Blur Reduction) and judder (Judder Reduction). Both sliders can be set in the range of 0 to 10, with each level affecting the degree of smoothing, so everyone can find their sweet spot. We present a setting that allows for slight smoothness without the soap opera effect.

The panel of TCL C855 features a very good response time. This is especially important, as VA panels often have issues with so-called ghosting, which is the effect where a black halo can be noticed behind a fast-moving object.

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.

The TCL C855 television is equipped with full HDMI 2.1 ports with a bandwidth of 48 Gb/s. During our tests, we confirmed the seamless operation of all functions that come with this standard. As you can see, all the checkboxes light up green, which will certainly be appreciated by gamers, both console and those using the television as a computer monitor. Additionally, the TCL C855 supports both AMD FreeSync and NVIDIA's G-Sync, which can be easily activated in the graphics card settings. Users with very powerful setups can provide a 144 Hz signal to the C855, which the television handles effortlessly. It's also worth mentioning the implementation of the HGIG mode, which, due to the shortcomings of the "Game" mode, is overly bright, making it difficult to configure properly on-screen. Fortunately, the television performs excellently with the Dolby Vision format.

The TCL C855, as one of the first manufacturers, has equipped its televisions with a special GameBar feature that allows extensive setting changes on the fly, without the need to exit the game. It includes functions such as an additional crosshair grid, black level correction, and settings for individuals with disabilities. In the photo, we see the next generation of this solution.

In summary, the TCL C855 television will be an ideal solution for those looking for a screen for any kind of electronic gaming. With all the features supporting such entertainment, it is incredibly engaging. It should also be emphasized that it has very low input lag, regardless of the selected settings, including with the Dolby Vision HDR format.

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.
