TCL C855 vs Philips PML9009 / 9019 / 9059

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.

Philips PML9009 doesn't really operate at the highest values in HDR materials. Most effects with brightness around 550 nits won't leave us thrilled with the lighting effects, although they are quite stable, which is a plus, and a considerable difference can be felt between SDR materials. It's worth noting that we can achieve a good result only in one scenario, that is in the film "Gemini," where the flashlight as the sole light source can really shine. Why in this scene? The answer is quite simple. The scene itself doesn't have a large amount of black, and the flashlight isn't as large an object as the sun in the first and last scenes. Overall, the brightness measurement results in HDR materials aren't a solid basis for recommending this television for viewing productions that use a wide color gamut. However, it's worth mentioning that this model can cover it in a not too bad 93% degree in the case of the DCI-P3 palette.

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.

The best factory mode used during our tests was "Filmmaker". Here, we will examine both SDR and HDR content. The key differentiator is primarily the EOTF curve in the wide colour gamut materials and gamma in those recorded "the old way". Starting with SDR films and series and the most basic thing we can observe, which is white balance, we see a significant red colour dominance. This led to a yellow tint across the whole image, causing unnaturally looking faces and yellowed whites. This issue is also clearly visible on the "ColourChecker" palette, where all colours have shifted towards their warmer counterparts. Looking at an even more significant graph, the gamma responsible for the contrast of the image, we see considerable errors beginning right from the start. From the left, the value we measured, indicated by a combined ellipsis, clearly spiked upwards, causing complete merging of details in the darkest scenes. This state of affairs persisted up to 10% brightness on the screen, after which it dove below the reference orange line, leading to a deterioration in contrast, which, as we know, Philips PML9009 is already lacking. In HDR materials, white balance issues were very similar to those in SDR content. The discrepancy appears when checking the EOTF curve, which governs the rate of brightness increase and severely limited it, resulting in an unnaturally dark image. As for the colours themselves, there were more reasons for concern here, as the television's low luminance caused a huge disparity between the actual state and the correct one, which is perfectly visible on the error graph, often exceeding the scale.

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.

Philips PML9009, like most leading manufacturers, has been providing advanced tools for calibration processes for years. Here we find 2-point and 20-point greyscale adjustments, as well as an advanced CMS (Color Management System). The differences resulting from calibration are evident, and even someone who doesn't pay attention to image quality (although there probably aren't many like that here) will notice the positive difference. Both SDR and HDR materials have undergone quite a transformation. The former and the latter have primarily shed the ugly yellow tint resulting from the red colour dominance in white balance. As for the SDR materials and gamma, although it is not perfectly modelled and still loses dark details, the rest of it is at more than a decent level, and minor errors will not be noticeable. The colours themselves look far better, and with low deltaE errors, they are almost reference-quality. On the other hand, HDR materials, due to the unit's low luminance, have not been optimised as we would have liked. Although the white balance has been largely normalised, a slight blue tint can still be observed here and there. Fortunately, the EOTF curve turned out to be much more accessible, allowing for practically perfect geometry. Unfortunately, due to the screen's too low brightness, the colour errors remain quite high.

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.

Judging by how PML9009 Philips handled tonal transitions, the image scaling test should perform just as well. This time, we are checking the TV’s algorithms responsible for enhancing the quality of images that were recorded in lower quality. Such images can be found, for example, in various TV shows or older films. In this regard, Philips PML9009 performs quite mediocrely and drastically blurs the image. This is particularly noticeable on fine branches or the model's hair.

Let’s revisit the issue of tonal transitions, which performed remarkably well. Within the unit, we will find several levels of smoothing. Even the lowest one can effectively eliminate any jerky tonal transitions and will be suitable for the vast majority of materials. More importantly, none of the settings for this function soften the effect of film grain, which is extremely important in terms of alignment with the director's vision. However, we would like to point out that sometimes it may turn out that fine details are blurred.

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.

Philips PML9009 has been equipped with a panel that has a native refresh rate of 120 Hz. This is the essential minimum for watching all kinds of sports and is recommended for comfortable gaming in favourite titles on consoles or PCs. The manufacturer, for those who dislike the characteristic judder of footage recorded at 24 fps or those requiring a high degree of motion smoothness, such as when watching football matches, has prepared an effective system for improving the sharpness of moving images. In the dedicated tab, we will find a "Smoothness" slider responsible for eliminating judder and a "Motion Blur Reduction" setting that helps to increase the sharpness of dynamic elements. The function works very well and granularly, meaning each setting has a real impact on motion perception. With such a set, every user will find their sweet spot. In the picture, we present our choice, which is slight smoothing without the soap opera effect.

A matter directly related to motion is the response time of the pixels in the panel itself. The best in this regard are of course OLED panels, followed by units based on IPS and ADS screens, and lastly VA. Despite the generally good quality of the systems responsible for smoothening the image, the use of a VA panel carries consequences in the form of black smear behind fast-moving objects. Although in the tested television this should not occur frequently, it will be noticeable here and there.

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.

Philips PML9009, equipped with HDMI 2.1 connections with full bandwidth, supports all functions dedicated to gamers. The most basic ones, such as VRR and ALLM, are a given, but G-Sync, FreeSync, or playing in HDR Dolby Vision with low input lag are not. These features activate without any problems, and during the tests conducted, they presented no obstacles. Such preparation of the television is certainly its strong point, and it can be said that it is a unit dedicated to gamers. For more advanced users, we also mention that the PML9009 is equipped with the HGIG mode, which will be particularly felt by gamers, as there are still relatively few games that support Dolby Vision. This mode primarily allows for the adjustment of HDR effects to the capabilities of the television on a special board, to prevent dimming and burning of the image.

The television additionally implements a special menu - GameBar. This allows for editing unit settings "on the fly," meaning without having to exit the game. In it, we will also find functions such as activating a crosshair or black level correction for better visibility of opponents in shadows.

In a brief summary of this paragraph, the Philips PML9009 is a unit that will undoubtedly attract gamers' attention. Thanks to its versatility, it will allow for playing any title in the highest quality without compromises. Especially since features such as VRR, ALLM, G-Sync, FreeSync, or gameplay in HDR Dolby Vision will provide an even greater immersion in the favourite title.
