Compare: TCL C855 vs Philips PML8709

Once again, the manufacturer demonstrates that although it is a relatively young player in Poland (but not worldwide) in the RTV market, it certainly cannot be said that it is a second-tier choice. The television TCL C855 is an incredibly versatile device that performs well in various applications and excels in its price class. Thanks to the Mini LED backlighting, the results of contrast and blacks are very solid, allowing for a deep and vivid image. It is worth noting that the television's algorithm effectively manages to maintain black uniformity, and blooming effect is rarely noticeable. This backlighting is also a strong point of the television in HDR materials, although with some caveats. TCL C855 can achieve a brightness of up to 1800 nits, which is an impressive result; however, brightness can drastically drop to around 200 nits when a bright but small element appears on the screen. Another drawback is the boost in mid-tones, which can lead to a loss of contrast and a decrease in image fidelity with the director's vision. The television also performs excellently when connected to a console or powerful PC. In this category, TCL C855 truly showcases its power, offering incredibly low latency and high-quality gameplay, made possible by the full implementation of HDMI 2.1 features. The Google TV operating system is another advantage, providing users with nearly unlimited installation options for applications, even those from outside the official store, thanks to support for APK files.

In summary, TCL C855 is the ideal choice for those who know what they expect from a television. It is a good, versatile piece of equipment that, although not perfect, offers excellent picture quality, low gaming latency, and a flexible and robust operating system.

The Philips PML8709 is a model that stands out in the offerings of the Chinese-Dutch manufacturer due to its uniqueness. Instead of the classic Philips operating system - TitanOS, we find the already well-known Google TV here, which provides extensive personalisation options and access to a vast library of applications. This television tempts us with very good contrast on one hand, while on the other hand, it surprises with a few unusual design decisions. In terms of picture quality, the PML8709 offers very good contrast, which, combined with wide colour gamut coverage, ensures excellent colour reproduction – especially after calibration. Despite a 60 Hz panel, the television is also suitable for occasional gaming thanks to support for features such as ALLM, VRR, and a low input lag of around 13 ms. On the other hand, Philips has deprived this model of one of the greatest advantages of its televisions – the Ambilight system. This unexpected move may disappoint many brand fans. Another weak point is performance in HDR – despite promising contrast results, the television performs averagely in this category. The average brightness and issues with details in brighter scenes give the impression that something has evidently gone wrong in the implementation of this feature. The Philips PML8709 is a television full of contrasts. On one hand, it offers solid black quality and interesting solutions for gamers, while on the other hand, some limitations, such as the lack of Ambilight and average brightness, mean that it is not a model without flaws. It is a good choice for those who value the versatility of Google TV and are looking for a television for everyday use.

TCL C855 uses a high-contrast VA panel. The ANSI contrast (without dimming) was a very decent 5238:1, which allows for at least very good black levels. Additionally, the panel itself is equipped with multi-zone Mini LED backlighting, which is divided into 1344 independent dimming zones for the 65-inch model. Such a number allows for very good results in our tests. It is worth noting that TCL, as one of the few manufacturers, offers such a specification without spending excessively large amounts of money, unlike the classic quartet of manufacturers. As you can see, in the vast majority of scenes we prepared, the results are impressive, particularly in the first three, as even in the third one, with a score of 54,000:1, it cannot be said that the black levels and contrast are weak, as they are more than satisfactory. These deteriorate in two scenarios: scenes with film stripes and when there are many elements surrounded by black on the screen. And while the last of the test scenes still has excellent contrast, the final tested scenario shows some blooming in the blacks. The frame from the film "Oblivion" performed exceptionally well on the TCL C855, with the level of black comparable to OLED screens, which is quite an achievement. It is also worth noting the good separation of lights, which is not easy to achieve. Our flagship scene from "Sicario 2" performed equally well in terms of contrast, but it is clear that details in the blacks on the first, second, and third planes tend to disappear. The operation of the backlight control algorithm also deserves praise, which minimizes the halo/blooming effect to an absolute minimum. However, it is worth noting that very small elements, such as stars, the TCL C855 can sometimes completely dim.

The model name 8709 "PML" refers to Philips mini-LED technology, but can we really call its backlighting that? In the 65-inch version, we counted only 96 local dimming zones. For mini-LED standards, this number seems too low, which raises questions as to whether we are actually dealing with a true mini-LED here. However, if we look at the black quality, the television performs quite well. On the first two test patterns, as well as in less demanding scenes, the picture is quite decent – blacks are deep and contrast is satisfactory. Problems begin, however, in more complex scenes, such as the last three test patterns, where small light elements appear on the screen. The local dimming algorithm seems to "get lost," unable to decide whether to brighten or darken a given area. The result is visible errors – reduced black quality and unevenness of the picture. An example of the local dimming zones' operation can be seen in a scene from the film Sicario 2. You can see how the dimming zones try to reproduce details, but at the same time, this leads to a slight brightening around the helicopter lights. However, despite these shortcomings, the black level in the Philips PML8709 is quite good, especially considering its price class.

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. This situation is, however, regularly observed in this brand, so it was not a surprise to us. The first and last scenes, featuring large elements of light, look almost phenomenal, "shining" with brightness levels of 1470 and 1820 nits respectively. Such effects will certainly cause more than one person to squint, while simultaneously feeling the extraordinary dynamism of the scene itself. You can truly feel as if you are inside the film. The situation changes dramatically when small or minor elements with high luminance surrounded by black appear on the screen. The TCL C855, in order to avoid the halo effect, significantly reduces brightness to a level of even 240 nits, which is a disappointing result, causing the film to not appear as if it was recorded in HDR. The HDR effect in the TCL C855 makes watching dynamic scenes more engaging, allowing the viewer to feel as though 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 adjusted for scenes with a large amount of detail, which enhances viewing comfort.

Looking at the results of the contrast, we expected that the algorithms responsible for the operation of zones in the Philips PML8709 would be at least decent. However, what we encountered during testing is difficult to explain. The average brightness we managed to achieve was only 350 nits, which is definitely too little to fully enjoy the effects of HDR. In practice, the television barely stands out against the backdrop of an average SDR. The situation becomes even more surprising for test scenes, such as the second one from the film Life of Pi or Sicario 2. Small light elements reach only 120 nits there, making them practically imperceptible. Such a level of brightness is completely at odds with contemporary HDR standards and significantly diminishes the experience of watching high-quality content. The only bright spot in this category is the very good coverage of wide colour gamuts – DCI-P3 at 97% and BT.2020 at 83%. This means that the colours are saturated and well-reproduced, which may improve the overall experience of watching HDR materials, if only a little. However, the lack of adequate brightness means that even this cannot save the Philips PML8709 in this category.

The best factory mode for the TCL C855 is "Film," and it is on this mode that we conducted all our tests. Like any mode predefined by the manufacturer, it had its drawbacks that are worth correcting to achieve an image as close as possible to what the film producer intended. We will examine the colour characteristics in both SDR and HDR materials. Looking at the first, we see a noticeable dominance of green in the white balance, which, as you might imagine, resulted in an unpleasant greenish tint across the entire image. Observing the very important gamma chart, which is responsible for the image's contrast, 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 the image to be overly contrasted, merging details into a dark blob. This situation persisted for quite some time, up to 20% of the chart's value, before then dipping below the reference. This, in turn, meant a brightening of the image and a significant drop in contrast. The factory mode performed slightly better in HDR materials, as the white balance looked quite good, except for the second half, where green once again took precedence. 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 was something we could also observe in the scene from the film "Pan" in the paragraph checking the TV's HDR.

Although theoretically the Filmmaker mode on the Philips PML8709 should provide natural colour reproduction, in reality it resembles store mode more closely. In the white balance, both for HD and 4K content, there is a clear dominance of the blue colour. This causes the image to appear washed out and cold, which is particularly noticeable in the comparative photo below.

The brightness characteristics also leave much to be desired. Both the gamma and EOTF curve show excessive screen brightening. As a result, there is a loss of detail in both the brighter and darker areas of the image, which further diminishes its credibility and naturalness. Bright elements appear unnaturally flat and lacking in variety.

These significant issues in white balance and brightness characteristics lead to noticeable errors in colour reproduction, which can be easily seen in films as well as in the Colour Checker test. The colours are inaccurate, impacting the overall image quality and visual experience. The factory settings require significant improvement in order to fully enjoy the potential of this television.

TCL, like the vast majority of manufacturers, provides advanced calibration tools in its televisions. Here we find 2- and 20-point adjustments for greyscale 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. The performance with HDR materials was somewhat poorer, as the TCL C855 did not allow us to model them adequately. We were only able to slightly adjust the EOTF curve and significantly improve the colours themselves.

Philips offers advanced image calibration tools in its televisions, which we decided to fully utilise. The results? Although we managed to improve many aspects, it was not without difficulties. White balance was one of the biggest challenges – despite our efforts, this can be described as a fight against windmills. We managed to correct it significantly, resulting in the image now looking much better than in the factory settings, but it is still far from perfect. Particularly in some scenes, a subtle dominance of blue is visible, although not as intense as before. We achieved a substantial improvement in brightness characteristics – gamma now appears much more stable. The EOTF curve initially looks correct, however, when analysing film content, it is evident that the television struggles to maintain the appropriate characteristics. The algorithms are "battling," trying to adjust brightness, which may stem from the limited number of dimming zones that do not always cope with more complex scenes. Overall, the image after calibration looks much more pleasing to the eye – colours are more natural, and errors in colour reproduction have been minimised. Although it is still not perfect, the Philips PML8709 now performs significantly better than in the factory settings.

Nevertheless, an important aspect in assessing image quality is tonal transitions. To obtain a clear image free from posterisation effects, the television must demonstrate very good algorithms for smoothing out colour gradations. We must admit that the one used in TCL C855, named "Gradual Smoothing," is among the best we have had the opportunity to test. Practically every scene performs very well here and there is nothing to criticise. The best example of this is the scene from "The Green Knight," which is the most demanding due to the vast amount of fine and subtle transitions in the mist. The C855 effectively smooths out everything contained in the scene and allows the full suspense to be felt. The only moment where a slight posterisation can be observed is in a shot from the film "The Green Knight," where the reds in the upper left section of the screen stand out from each other.

The fluidity of tonal transitions in the Philips PML8709 is at a very high level. The colour gradation is incredibly smooth, and the transitions between shades appear natural and detailed. Even in more demanding scenes, the television performs excellently. Minor issues may arise with bright elements, where the gradation may be slightly less precise. However, these are such subtle differences that only the most discerning purists will notice them. For most users, the effects will be fully satisfying, and the image will maintain its impressive quality.

Once again, we will take a look at the function of smoothing tonal transitions, but this time also at image scaling. The latter is particularly important when watching lower-quality materials, such as certain television programmes or older films. We will focus on the function responsible for tonal transitions. Interestingly, just like in the scenes of the previous test, it performed excellently and smoothed out practically all the inconsistencies; however, here it had problems. Using the menu responsible for this function, we found that no setting - even the strongest - was of any help.

Image scaling in TCL C855 is described 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 for our eyes. Even the small, fine branches do not have jagged edges, and there is no white halo around figures, which is characteristic of inferior scaling systems.

The distortion reduction function in the Philips PML8709 smooths tonal transitions, but its effectiveness leaves much to be desired. We recommend setting this option to "Medium" – at this level, the effect is noticeable but not excessive. Unfortunately, compared to other Philips models, the smoothing effect is less effective, which means that certain tonal transitions may still appear a bit uneven. An additional drawback is that this function also smooths out other details, such as the textures of materials like a shirt, which can affect the sharpness of the image.

When it comes to image scaling, the television performs very well. The image appears plastic and free of noticeable "jaggedness." This effect may appeal to many users, although some may prefer a more pronounced appearance. Fortunately, the television allows for sharpness adjustment, and this enables us to tailor the image to individual preferences.

The maximum refresh rate we can set on the TCL C855 is 144 Hz. Naturally, this is only possible by connecting the TCL C855 television to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a lot of motion dynamics. For those requiring high image fluidity, the manufacturer has implemented a multi-stage motion smoother. This has been divided into two separate sliders regulating the sharpness of moving images (Motion Blur Reduction) and flicker (Flicker Reduction). Both sliders can be set in the range from 0 to 10, with each increment affecting the level of smoothing, so everyone can find their sweet spot. We present a setting that allows for slight smoothing without the soap opera effect.

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

The Philips PML8709 is one of the few models with mini-LED technology on the market, offering a refresh rate of 60 Hz. Although it is not a panel for the most demanding gamers, it should satisfy those who mainly watch films. The television is equipped with the "Motion Style" function, which is a motion smoother that allows you to adjust the smoothness of motion according to preferences – from a more "plastic" look to a cinematic aesthetic with clearly visible frames.

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

The TCL C855 is one of the first manufacturers to equip its televisions with a special GameBar, which allows for extensive setting changes on the fly, without the need to exit the game. It features functions such as an additional crosshair grid, black level correction, and settings for people with disabilities. In the picture, we can see the next generation of this solution.

In summary, the TCL C855 television will be an ideal solution for those seeking a screen for all sorts of electronic gaming. Thanks to all the features supporting such entertainment, it is incredibly engaging. It is also important to highlight the very low input lag, regardless of the selected settings, including with the HDR Dolby Vision format.

Philips PML8709 is a television aimed more at casual gamers, primarily due to its 60 Hz panel, which may not meet the expectations of the most demanding users. However, for those who appreciate gaming at a more measured pace, this model may prove sufficient.

The television offers several gamer-friendly features, such as ALLM (automatic switching to game mode) and VRR (variable refresh rate), which help deliver smoother visuals without annoying stutters. Furthermore, in terms of HDR, it includes an HGiG implementation that adjusts HDR effects to the specifics of games, providing a more natural image in properly optimised titles. Unfortunately, it lacks support for Dolby Vision mode, which may be noticeable in games that utilise this format.

A nice addition is the presence of a basic "Game Bar," which allows for quick viewing and modification of the most important gaming-related settings. This is a simple but useful feature, especially for those who often switch configurations between different types of gameplay. Despite some limitations, Philips PML8709 offers a solid set of features for less demanding gamers.

The delay times of the TCL C855 are remarkably low in every scenario. Even the most avid gamers will surely appreciate the very low input lag of just 7 ms at demanding 4K 120 Hz settings with HDR. Furthermore, the delays at these same settings, but with Dolby Vision HDR enabled, remain at the same level, which is not so obvious in the case of competing models. Consequently, the TCL C855 deserves the highest rating and recommendation.

Philips PML8709 performs very well in terms of input lag. At the supported resolutions, results around 13 ms are more than sufficient to ensure comfortable gameplay. Such a response time means that even more dynamic games do not cause annoying delays. As a result, players can enjoy smooth gameplay without unnecessary stress.

TCL C855 when connected to a computer as a monitor performs very well. This is due to the very low latency between the mouse, eye, and screen, as well as excellent font clarity, which results from the correct implementation of chroma 4:4:4 at all resolutions, including 4K@144Hz. The subpixel layout is BGR, which does not negatively impact usage in Windows. However, the situation may change when using macOS or other software that cannot adapt fonts to this subpixel layout. Additionally, the television has minor issues with displaying fonts on a black background, which is why we deducted some points.

The Philips PML8709 offers a dedicated mode for PC, but its capabilities are quite limited. The television does not support chroma 4:4:4, which significantly affects the readability of fonts – text appears blurred and is difficult to read, disqualifying this model for those planning to use it as a monitor for work or document viewing. Additionally, although in G-Sync tests the television showed compatibility, the image when using this function is very unstable, with frequent stuttering. Such unpredictability eliminates the benefits that adaptive sync support should provide.

The only positive aspect in the context of working with a PC is the low input lag, which may be an advantage for those using the television mainly for gaming. Nevertheless, the limitations in chroma support and issues with G-Sync make the PML8709 less than ideal for PC users.

A widely known drawback of VA matrixes without an angular coating is their poor performance in terms of viewing angles. The same is true for TCL C855, where even a slight shift off-axis leads to significant image washout and colour degradation.

The Philips PML8709, equipped with a VA panel, offers average viewing angles typical for this type of display. The image deteriorates in quality when viewed from a sharper angle – colours wash out and contrast significantly decreases. This is a characteristic feature of VA panels and it is worth keeping in mind, especially if we plan to watch the television from different positions in the room. However, for viewers sitting directly in front, the picture remains clear and well-reproduced.

The glossy finish of the panel in TCL C855 did not allow for the highest rating in terms of the television's performance during daytime viewing, although it is precisely because of this that the blacks during the day are very good. Thanks to the high brightness in SDR content, the actress's face stands out strongly against reflections. A downside of the panel, however, is that light falling directly on the television "spills" further rather than being contained in one place. Generally speaking, if sun rays do not hit the panel, TCL C855 will be a very good choice for brightly lit rooms.

The Philips PML8709 is equipped with a satin matrix, which performs moderately well in reducing reflections. In moderately lit rooms, reflections will not be too bothersome; however, in heavily sunlit conditions, the situation can become problematic. An additional challenge is the relatively low screen brightness, measuring around 330 cd/m². This level may prove insufficient to ensure comfortable viewing in bright rooms, where the image may appear too dark and unclear. The television will perform better under controlled lighting conditions, but for those looking for a model that handles daytime viewing well, this may be a significant limitation.

TCL C855 operates on the Google TV system, which is a significant advantage compared to televisions equipped with proprietary systems from manufacturers, where installing applications from a USB drive may be difficult or often downright impossible. Thanks to Google TV, we have the ability to install practically any application, both from the official store and directly from internet repositories via APK files.

This system also offers many conveniences in terms of control. We can connect a keyboard with a touchpad, which greatly facilitates inputting queries. Additionally, thanks to integration with Google, we can use voice control functions with the remote, which works very well, although there are occasional minor issues with the translation of functions and options. It is worth adding that Google TV regularly receives updates that improve functionality and introduce new options. We can also confirm that according to reports from users of older models, the software can have its bad days, and sometimes it experiences a "bad day".

In summary: Google TV is currently one of the most popular systems on the market. Thanks to an efficient CPU, it operates very smoothly, does not freeze, and does not have issues with lagging for a significant part of its usage. This is definitely the best option for those who want to make the most of the capabilities of the TCL C855 television and value the openness of the system.

Philips PML8709 runs on the Google TV operating system. This is quite a surprising choice, considering that it is not a flagship model of the brand. Fortunately, it has avoided the implementation of the less popular TitanOS, which can be seen as a plus. Google TV offers a well-known, clear interface and wide possibilities for app installation, making the television more versatile.

In terms of usability, the television performs solidly. Daily use of the device is pleasant, thanks to support for voice search in Polish. The ability to connect peripheral devices such as keyboards, mice or headphones via Bluetooth increases its functionality. Unfortunately, the PML8709 does not offer more advanced options like USB recording or PiP (picture-in-picture) functionality, which may disappoint more demanding users.

An interesting fact, and quite a surprise, is the absence of the Ambilight system, for which Philips is widely known. The decision to omit this technology in the PML8709 model seems inexplicable, especially since Ambilight is often cited as one of the greatest advantages of televisions from this brand.

The default media player on the TCL C855 performs very well with practically all the content we have prepared for it. Virtually every video format is supported. However, a notable deficiency may be the lack of a feature to change the font colour. There are hardly any issues with photos and their maximum resolution. It is worth noting negatively the absence of support for Apple's HEIC and SVG files. On the other hand, audio files can be played without any problems, and we do not believe that a large portion of you uses AIFF or DSD64. However, an undeniable advantage of the C855 and its operating system is that we can download another player from the app store at any time, which will play everything.

Philips PML8709 performs well in playing multimedia files from USB. The television should not have problems with handling most popular video, audio, and photo formats, making it a versatile tool for home entertainment. Files are read smoothly, and the interface of the built-in player is simple and intuitive.

However, a significant drawback is the lack of support for Polish characters in subtitles, stemming from the incomplete implementation of the UTF-8 standard. Subtitles with Polish characters are displayed incorrectly, which can be frustrating for those watching films in their native language. This shortcoming means that users seeking full compatibility with subtitles may be forced to resort to external multimedia players.

When evaluating the sound on the TCL C855, we pay attention to several key aspects, such as whether the tones are clearly audible and do not clash with one another, as well as whether none of them dominates the others. In the case of the TCL C855, the sound is positively presented – it is balanced and does not evoke any negative feelings. Generally, the sound is simply good.

For those with a home cinema system, the TCL C855 offers a wide range of audio codecs, including the two most important: DTS-HD Master Audio and Dolby Atmos. This ensures high audio quality that will satisfy users seeking better audio experiences.

The sound quality of the Philips PML8709 is average and standard for a television equipped with speakers rated at 2 x 10 W. The sound is sufficient for everyday viewing, but it is difficult to expect depth in the bass or clear details in more demanding scenes. On the plus side, it does support Dolby Atmos and DTS.
