Compare: TCL C855 vs TCL P7K / P79K

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 time has come to gather all observations. The TCL P7K / P79K is a television that cleverly juggles compromises, offering much more in its price range than we could have expected. Its undeniable asset is the VA panel, guaranteeing deep blacks and high contrast, and the surprisingly rich package for gamers (with VRR and support for 120 Hz at lower resolutions) makes it a phenomenal proposition for console owners. The whole is tied together by the functional Google TV system. Of course, the low peak brightness means that HDR content lacks spectacular bursts, and the TV's performance in sunlit rooms is limited. And although, at its relatively low price, the P7K / P79K is quite a decent option, its biggest rival turns out to be… its more refined sibling, the P8K. Often, FOR a small additional payment, we get a device of a higher class – with a native 4K 144 Hz panel, significantly better audio system, and generally higher quality of operation, which is reflected in its much higher rating on our portal. Therefore, the final verdict must be as follows: if your budget is absolutely non-negotiable, the P7K / P79K will be a good and cost-effective choice. However, if you can afford to add a small amount, the P8K model will offer significantly more and will ultimately be a more satisfying investment.

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.

In the discussion about image quality, the conversation almost always begins with the issue of black depth and contrast, which are parameters that define the plasticity and realism of the observed world. Here, the TCL P7k/P79k immediately lays its strongest asset on the table – a VA panel. Its construction is what makes the native relation between the brightest and darkest parts of the image more than satisfactory, especially in the context of the price segment that this model represents. In the majority of scenes, the black achieved has a noble depth, which allows for building an engaging spectacle for the viewer. To illustrate the scale, it is worth mentioning that competing constructions based on IPS panels often offer results that are even four times, and sometimes five times, lower, which in direct comparison represents a chasm. Of course, when entering the territory of models oriented towards affordability, we must be aware of certain compromises. Therefore, we will not find an advanced local dimming system in the discussed television, which could further enhance the sense of contrast. However, the absence of this feature is fully understandable and constitutes a logical consequence of positioning the product in the market – this technology in TCL's portfolio for 2025 has been reserved for higher positioned, more prestigious series marked with the letter "C".

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.

When turning to the assessment of HDR performance, we must be clear and without marketing embellishments: the P7K/P79K is not, and was never intended to be, a master in this field. The maximum peak brightness that this panel can generate hovers around a mere 300 nits. This represents a threshold, a kind of thin red line between what can be considered a barely satisfactory HDR signal and what is, in fact, not much different from standard dynamic range (SDR), unfortunately leaning towards the latter. Synthetic tests found brutal confirmation in reality – our measurements taken during movie screenings showed that luminance in key bright portions of the scenes rarely exceeded the ceiling of 200-250 nits. Thus, this is not a television that would allow content realised in a wide tonal range to spread its wings, and this must be openly admitted.

Unfortunately, the issue of colour reproduction is presented with equal restraint. Although the manufacturer positions this model within the "QLED" family, thanks to the use of a PFS LED filter, the results do not match the heightened expectations. The coverage of the wide DCI-P3 colour gamut reaches only 86%. In the context of the market, this is at best an average result, as most devices that employ additional layers to expand the colour spectrum easily achieve values at a minimum level of 90-92%.

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.

Every accurate assessment of image quality must begin with selection of the most optimal factory mode. In the case of the tested model P7K/P79K, the choice was made without hesitation for the "Film" mode. It is this mode that presents an image closest to the intentions of the creators, avoiding both the exaggerated brightness of the dynamic mode and the excessive dimming known from eco settings. And it must be admitted that, for a device in this price range, the factory calibration is surprisingly decent, although it has not escaped a few missteps. The most noticeable flaw turned out to be the not completely correctly set white balance. A slight dominance of the blue component gives the image a subtly cool, cold character, thus deviating from the exemplary neutrality that the director wanted to show us. The television performs much better in reproducing the greyscale in the standard dynamic range – the gamma curve is nearly exemplary. The only minor reservation could be made regarding the darkest parts of the image, where a slight deviation from the norm causes a loss of some detail in the shadows. The most serious challenge for the TCL software, however, was interpreting the HDR signal, as illustrated by the course of the EOTF curve. The television follows its own, quite free path here – the darkest details are disproportionately brightened, after which there is a noticeable slowdown in the increase of brightness for midtones. Fortunately, most of these imperfections are software-related issues that can be eliminated. With this thought in mind, we began the process of professional calibration.

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.

The calibration process turned out to be spot on, particularly in the context of standard dynamic range (SDR) content. We successfully mitigated the television's tendency to emphasize cool tones, restoring the whiteness to its natural neutrality. Moreover, precise adjustments allowed us to correct a slight error in the gamma curve, ensuring that the darkest parts of the image regained their proper depth, without any trace of unnatural brightness. The effects are measurable and impressive – in the ColorChecker test, the overwhelming majority of colour reproduction errors fell below the perceptual threshold, achieving a deltaE value of under 2. This is a result that pricier models would not be ashamed of. Unfortunately, when it comes to HDR content, we encounter a barrier in the form of the inherent limitations of the panel itself. And although we managed to bring the colours into line, the software's characteristics mean that the television still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. In summary, calibration adds immense value, but one must be aware that it cannot overcome certain physical barriers. The slightly elevated black level, due to the lack of local dimming, along with limited peak brightness, means that HDR content may not always be able to showcase its full potential. This is simply not the primary task of this display; its true strength, especially after professional tuning, lies in the viewing of SDR material.

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 issue of the fluidity of tonal transitions, or popular grading, is another area where the P7K / P79K evokes mixed feelings and surprises with its dual nature. If we were to evaluate solely its ability to render smooth colour gradients, we would undoubtedly give it a solid score of 8/10. Unfortunately, this positive image is marred by the use of very aggressive and unpleasant dithering. This artefact is particularly noticeable on demanding test patterns – such as the one depicting an actor submerged in red water – where rough, unnatural texture appears on uniform colour surfaces, betraying the digital nature of the image. This is all the more disappointing, as it is not a new issue. It seems to be a sort of inheritance from previous generations of budget TCL models, which is a pity, as it represents a flaw on what is fundamentally a quite competent image and is a mistake that could have been avoided.

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.

After a series of harsh evaluations, fortunately, the time comes for praise, and this is due to the TCL AiPQ image processor for its work in the field of digital processing and content scaling. It should be noted right away that we are not talking about the level known from flagship designs; however, in the price segment represented by the P7K/P79K, the results achieved are more than solid. The feature for smoothing tonal transitions performs particularly well, effectively eliminating posterisation, which are the characteristic bands often visible in highly compressed materials, for example, from the ChooseTV service. The algorithm adeptly removes unwanted gradients, which ultimately looks really good. The television also handles upscaling competently, which is the task of elevating low-resolution materials to 4K standard. The resulting image, although it may initially seem a bit too sharp, fortunately, is not a problem. The software allows for free adjustment of this parameter using a sharpness slider, making it easy to customise the final appearance to personal 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 issue of fluidity and sharpness of the image in motion is inextricably linked to a fundamental parameter of the matrix, and in the case of the TCL P7K/P79K, we are dealing with a panel with a native refresh rate of 60 Hz. This specification defines its capabilities from the outset and makes it difficult to unequivocally recommend it to enthusiasts of dynamic sports broadcasts. During fast camera movements, the image loses sharpness, and the panel also shows a slight tendency to smearing, which may be noticeable to more sensitive viewers. Fortunately, not everything in this aspect has been left to chance. The manufacturer has implemented a simple motion smoothing system, which is primarily used in film material recorded at 24 or 30 frames per second. Thanks to a dedicated slider, users can decide for themselves the final character of the motion – from maintaining a fully cinematic, slightly juddery image to achieving a very smooth, almost theatrical effect. It is a simple but effective tool that allows users to tailor the viewing experience to their own preferences.

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.

Although on paper the native 4K@60Hz panel might suggest that the TCL P7K/P79K is not a television tailored for gamers, the reality is surprisingly different. On the contrary, the manufacturer has ensured a rich package of features that make it a very friendly companion for next-generation consoles. Onboard, we find key technologies such as ALLM, which provides automatic switching to low latency mode, and VRR, or variable refresh rate, which eliminates screen tearing. The list is complemented by support for Dolby Vision Gaming and a simple yet functional Game Bar. However, the real and extremely pleasant surprise is something else. It turns out that the television easily supports a high refresh rate signal of 120 Hz but at lower resolutions – 1080p and 1440p. This is fantastic news for console owners, who know well how rarely games run in native 4K at a full 120 frames per second. The ability to choose between higher resolution and doubled smoothness is therefore an extremely sensible compromise.

In summary, although the P7K/P79K may not be the target screen for the most passionate tournament players, for the casual or occasional console user, it offers a package of options that is hard to find among many competitors at this price.

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.

Complementing this rich package for gamers is a parameter that has a direct impact on comfort and performance in gameplay – input lag. Already in native 60 Hz mode, the television boasts an excellent result of just 15 ms. However, the real magic happens when switching to 120 Hz mode, where the lag drops nearly by half, reaching values below 10 ms. Such responsiveness ensures that every command from the controller is translated to the screen in the blink of an eye, which will be appreciated not only by professionals but by anyone who values smooth and direct interaction with the game.

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.

We finally come to an area that can undoubtedly be described as the biggest Achilles' heel of the TCL P7K/P79K – its compatibility with PC. It is paradoxical in that, on paper, everything looks promising. The presence of G-Sync and support for high refresh rates at lower resolutions might suggest that it would also be a great monitor. Unfortunately, practice brutally verifies these assumptions. The key issue is the lack of support for full 4:4:4 chroma sampling. In everyday use, this translates to terrible font rendering quality – these, especially the coloured ones, become jagged, surrounded by artefacts, and simply poorly legible. This is not the end of the story, as in PC mode, the problem of aggressive dithering also becomes evident, giving the entire image an artificial, overly digital appearance. The only consolation in this situation is the fact that in games we can take advantage of the additional hertz and G-Sync technology, but these are not advantages that could compensate for the fundamental deficiencies in displaying a static interface. The verdict is therefore clear: while as a screen solely for gaming on PC it might still hold its own, as a monitor for work or browsing the internet, the P7K/P79K simply performs poorly.

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.

When it comes to viewing angles, we enter the territory where VA panel technology dictates unavoidable conditions. As expected, this is the weak point of this model. It is enough to move away from the screen axis to observe a gradual degradation of the image: colours begin to fade, contrast noticeably drops, and black loses its depth. In direct comparison with IPS panels, which are renowned for their generosity in this aspect, the VA panel must concede superiority to its competitor. Is there any upside to this? Paradoxically, yes. Poor viewing angles are, after all, the price we consciously pay for the fundamental advantage of this technology – a significantly higher native contrast and deeper blacks when viewed head-on. Thus, it can be said that this is a television that favours viewers sitting in the 'ideal' spot, offering them a maximally vibrant image at the cost of versatility.

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 final practical test for any television is its daily performance in daytime conditions when it has to compete with ambient light. In this competition, the TCL P7K / P79K starts with a certain advantage in the form of a satin finish on the screen. Its structure handles direct reflections quite decently, diffusing them and protecting the image from excessive fading of colours or lightening of blacks. However, the passive struggle against reflections is one side of the coin. The other is the active ability to 'break through' bright surroundings, and here one of the model's key limitations comes to light. The previously mentioned peak brightness of around 300 nits is simply too low to ensure a fully comfortable and dynamic viewing experience in a brightly lit living room. In such conditions, the image may lack punch, and scenes with lower brightness can lose their clarity.

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.

Smart Features – the Power of Google TV

The heart and operating brain of the TCL P7K / P79K is the Google TV system, which is a significant advantage in itself. This platform opens access to an almost limitless library of applications from the Play Store, ensuring that we won't miss any key streaming service. Integration with other devices is exemplary – Apple users will appreciate the seamless collaboration thanks to AirPlay, and Windows and Android users can easily utilise screen mirroring features. One should also highlight Google Assistant, which performs exceptionally well with voice search in Polish, remaining one of the most effective and convenient solutions of its kind on the market. The system’s performance on the tested model can be described as "above average." The interface is mostly smooth, but during tests, there were occasional slowdowns and even sporadic "freezes" that required a moment of patience. Minor glitches can also be seen in the translation of some system messages, which can be clumsy – however, these are minor oversights on TCL's part that do not affect overall functionality.

Classic Features

In the era of smart systems, traditional television functions often take a back seat, and this is also the case here. A significant advantage is the inclusion of a classic remote control with a numeric keypad, which does not require precise aiming at the screen for communication, significantly enhancing user comfort. The presence of Bluetooth technology for connecting external devices, such as headphones or speakers, should also be regarded positively. However, this is essentially where the list of conveniences ends. It is evident that TCL has almost put everything on the Google TV card, treating classic functions as an absolute minimum. Therefore, we will not find options to record programmes from built-in tuners to a USB drive or the once-popular PiP (Picture-in-Picture) feature. This is, therefore, a basic package that simply works but does not offer anything beyond what is essential.

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.

The built-in media player in the P7k/P79k model is quite a puzzling case, placing us in a rather unusual situation. On one hand, its engine manages to decode most popular video formats, which is obviously good news. On the other hand, we encountered a surprising and frustrating flaw – the default app has a fundamental issue with correctly displaying Polish diacritical characters in subtitle files. Instead of letters like "ą," "ę," or "ż," empty squares or random, unreadable symbols appeared on the screen. Fortunately, thanks to the flexibility of the Google TV system, this issue can be easily circumvented. Installing an alternative, advanced player, such as the tried and tested VLC or KODI, fully resolves this inconvenience. The situation is particularly odd since we didn't encounter such a flaw in other TCL models we tested previously. We are therefore dealing with an obvious software oversight, which we hope will be fixed in a future update.

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.

In terms of the built-in audio system, the TCL P7k/P79k presents a level that can be described as functional and correct, but lacking audiophile ambitions. The speakers play quite loudly, and the dialogues in films and television programmes are delivered clearly and without distortion, which is crucial in everyday use. However, the soundstage definitely lacks a foundation in the form of low tones. This is a direct consequence of the absence of a dedicated subwoofer – an element that in the higher P8K series, represented by a large Onkyo subwoofer at the back of the cabinet, constituted the strength of its sound. Here, that element is simply missing, which makes the sound seem flatter and devoid of the depth that creates a cinematic atmosphere. We also noticed a peculiar aspect in the software – when attempting to set the maximum volume, the television automatically reduces it. It is difficult to determine definitively whether this is a form of protection against distortion or a minor software glitch; nonetheless, it’s a shame because the power reserves seem to be slightly greater.
