Our verdict

Hisense U7KQ with a size of 100" is clearly a better television compared to the smaller variants. The proprietary VIDAA system has a similar interface to other TVs (e.g., with Google TV onboard). It operates quickly and smoothly. It doesn't freeze or contain errors. The built-in media player sometimes had difficulties functioning, though. It's worth looking at the app test, as not all of them were available at the time of writing this review. The TV's features are quite extensive, and nearly everything we tested was successful. During day use, the high brightness of the panel is commendable, handling even brightly lit rooms well. When watching in cinematic conditions, we can count on good blacks, thanks to the VA panel supported by multiple dimming zones. The screen handles low-quality content (e.g., SD channels or DVDs) reasonably well, but a downside is the lack of a function to reduce posterisation (which involves clearly defined tonal transitions). It looks much better with 4K HDR movies as we have a wide colour palette and strong light effects. Support for Dolby Vision and Dolby Atmos is another advantage, although the speakers built into the screen are rather average. Sports enthusiasts will be pleased with the 120Hz panel featuring motion smoothing. When connected to a console, gaming on the television is very good due to the low input lag. Motion blur is moderate, meaning that very rarely can slight "trails" be noticed when there is dynamic movement against a dark background. The lack of HGiG mode diminishes the visual quality of games in HDR format, while the absence of local dimming in VRR mode renders the latter feature useless. Overall, the picture quality can be described as good and appropriate for its price. There aren't any obvious flaws or unexpected advantages here, but the large size is a significant factor.

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

In summary, the 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 great picture quality, low gaming latency, as well as a flexible and expanded operating system.

Halo effect and black detail visibility:

The television is equipped with a VA panel, which has high contrast even without the support of local dimming technology. With the additional support of Mini-LED technology, the television is able to offer really good blacks, both in subdued, dark scenes and in mixed scenes where black is interspersed with bright elements. Suffice it to say that even in the most challenging test sequences, it achieved a result above 10,000:1. In a fully darkened room, zone dimming can sometimes be visible, appearing as a slight halo effect around text or bright areas lightening up when a bright object moves quickly across the screen. However, this is a normal phenomenon that isn't bothersome. The television, like most LCD screens with local dimming, has a moderate tendency to darken the image, particularly small light sources in dark scenes.

TCL C855 uses a high-contrast VA panel. The ANSI contrast (without dimming) reached a very respectable 5238:1, which allows for at least very good black levels. Additionally, the panel is equipped with multi-zone Mini LED backlighting, which is divided into 1344 independent dimming zones for the 65-inch model. This number allows for very good results in our tests. It is worth noting that TCL, as one of the few manufacturers, offers such a panel specification without spending excessively, unlike the classic big four manufacturers. As you can see, in the vast majority of scenes we've prepared, the results are impressive, particularly in the first three scenes, as even in the third, with a result of 54,000:1, it cannot be said that the black levels and contrast are weak, as they are more than satisfactory. These worsen in two scenarios: scenes with film strips and when there are many elements surrounded by black on the screen. And just as the last of the test scenes still has excellent contrast, in the final tested scenario, a slight blooming of blacks can be noticed. The frame from the film "Oblivion" performed excellently on TCL C855, and the level of black can even be compared to OLED screens, which is no small feat. It is also worth noting the good separation of lights, which is not an easy thing to achieve. Our flagship scene from "Sicario 2" also performed well in terms of contrast, but it is evident that details are lost in the blacks on the first, second, and third planes. The operation of the backlight control algorithm, which minimizes halo/blooming effects to an absolute minimum, deserves praise as well. However, it is worth noting that very small elements, such as stars, can sometimes be completely dimmed by the TCL C855.

TCL C855

Hisense U7KQ

Describing the HDR effect in the hundred-inch model Hisense U7KQ is not straightforward and requires a broader context. As can be seen, the results are highly variable, depending on the type of scene and the intensity of the bright effects that the television has to reproduce. In bright scenes, the device achieves over a thousand nits of brightness, translating to vivid and realistic images – these are exactly the effects we expect from equipment of this class. Unfortunately, the situation worsens in darker scenes. In mixed shots, such as those in the film "Gemini Man," the television still offers good brightness at around 700 nits, allowing for high-quality viewing. However, problems arise in very dark scenes where small light sources play a major role. The television does not fully utilise its capabilities here to avoid degrading the black levels in adjacent areas. As a result, there is no spectacular "WOW" effect, and such shots often do not give the impression of being realised in HDR technology.

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.

After calibration

The best factory mode we measured was “Filmmaker”. Despite this, its characteristics left a lot to be desired. Let’s take a look at the gamma chart, which is responsible for the depth and contrast of the image. First, we'll note the orange line running through the middle of the graph, starting at point 2.4. This is the reference value of the REC.709 standard. Now let’s look at the measured value, marked by a white, connected multi-point. Such a clear drop in gamma to a value of 2.0 meant a significant reduction in contrast, resulting in the image lacking appropriate depth, and the so-called “milk” effect was noticeable. The next thing we tested was the white balance. Though seemingly minor, if poorly adjusted, it can change the entire characteristic of the image. While the beginning of the chart looked quite promising, as we progressed further, the chart began to be dominated by two colours: red and blue. Due to the current state of affairs, all the materials we used for testing had an unpleasant tint in those colours. However, thanks to rich calibration tools, such as an advanced colour management system (CMS) and 2- and 20-point grey scale adjustments, we were able to significantly improve the display's performance in SDR materials, as confirmed by low deltaE errors and very well-modeled gamma and white balance.

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.

Color reproduction after calibration

7.8/10

6.9/10

In SDR mode, after calibration, the Hisense 100U7KQ television performs excellently. There is nothing to fault in terms of colour reproduction - both pastel and deeply saturated hues are displayed according to the Rec. 709 standard. This ensures that the image looks natural and in line with the director's vision. As a result, viewers can enjoy an authentic visual experience, with colours and tonal subtleties faithfully represented.

In HDR mode, however, there is a noticeable boost in bright tones. The television tries to enhance the image, which can lead to artificial brightening. This phenomenon becomes even more apparent in real scenes, where bright parts of the image can be excessively amplified. Although colours in HDR are generally good, they are intentionally boosted too much by the manufacturer, which may affect their naturalness.

This manufacturer's approach to displaying images in HDR mode may not be to everyone's taste, especially those who value authenticity and fidelity to original colours. However, for those who prefer more dynamic and vivid images, this bright tone enhancement can be an appealing solution, adding extra sparkle and impact to scenes.

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.

Smoothness of tonal transitions

10/10

9.2/10

Tonal transitions on the tested television can be described in one word: perfect. Throughout the testing sequence, where we played back very dark gradients from the most challenging scenes we know, there was not a hint of discontinuity or layers distinguishing themselves from each other. These impressive results testify to the high quality of the panel and advanced image processing algorithms. Of course, the ideal experience is maintained as long as we watch the television straight on – at an angle, dark shades can become quite pronounced, which is discussed in detail in the dedicated paragraph. It’s also worth noting that such a problem can be observed with lower quality materials, but this is not the television’s fault; rather, it's the lower quality of the source itself.

Nevertheless, an important aspect in assessing image quality are tonal transitions. To achieve a clear image free from posterisation effects, the television must demonstrate very good algorithms for smoothing out colour gradation. We must admit that the applied feature in TCL C855 called "Gradual Smoothing" is one of the better ones we have had the opportunity to test. Practically every scene performs very well here, and nothing can be faulted. The best example of this is the scene from "The Green Knight", which is the most demanding due to the vast number of fine and subtle transitions in the fog. The C855 effectively smooths everything present in the scene and allows the viewer to experience its entire suspense. The only moment where a slight posterisation can be noticed is in a frame from the film "The Green Knight", where the reds in the top left section of the screen contrast against each other.

Despite the television being equipped with a function to reduce posterisation called "Smooth Gradation", we did not notice a significant effect of its operation. Materials subjected to heavy compression, such as YouTube videos, still showed choppy, abrupt tonal transitions, which did not look particularly appealing. While this is due to the material itself and not the television, it would be good if there was a function to mask these issues, similar to those found in competing brands.

Image scaling, which is crucial when playing lower resolution content, we rate as average. Details are not overly blurry, and the image is not "smudged", however, there is noticeable jaggedness on the edges of objects, such as branches, and a halo effect around characters and text. While the television performs quite well, there is still room for improvement, especially in the context of displaying lower quality materials.

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.

The TV correctly receives a 4K signal up to 144 Hz, allowing for very smooth images in high resolution. When limited to Full HD resolution, the TV can handle even 240 Hz, but such a signal can only be obtained from a PC. Unfortunately, the use of this feature is limited by several factors.

Firstly, Full HD resolution on a large TV screen may seem insufficient, affecting image quality. Furthermore, the response time of the panel in this model is not short enough to fully utilise the refresh rate of 240 Hz. As a result, at such a high refresh rate, there is significant overdrive, which causes noticeable smearing and so-called "ghosting" behind moving objects.

It is also worth noting the motion smoothing feature in the TV, which operates up to 120 Hz. This is particularly useful when watching sports and movies, where motion smoothness is crucial. The TV offers stable operation of this feature, minimising the amount of generated artefacts. Motion smoothness can be adjusted using two sliders – one for smoothness in movies and the other for reducing smearing in sports content.

In summary, although the TV Hisense U7KQ offers impressive capabilities in image refresh rates, limitations related to the response time of the panel and appropriate resolution may affect the actual benefits of these features. Nevertheless, the motion smoothing function works very well, enhancing the experience of watching dynamic content.

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 Hisense U7KQ TV supports all the key features for gamers that users of Xbox or PlayStation consoles might expect. These features include support for high refresh rates, low input lag, and a game bar. Generally speaking, most of these features work well, providing a satisfying gaming experience.

However, the VRR (Variable Refresh Rate) technology does not function optimally. When VRR is activated, the TV disables local dimming, which significantly reduces image quality. In VRR mode, there is a lack of good contrast and high brightness in HDR mode, resulting in unsatisfactory image quality. In practice, this means that the VRR mode may be rarely used by gamers due to these limitations.

Additionally, the TV does not support the HGIG (HDR Gaming Interest Group) mode, which is designed to optimise HDR image quality in games. The absence of this mode leads to issues with double tone mapping—once in the TV and again in the console. As a result, the quality of HDR gaming is lower, which can affect the overall gaming experience.

In summary, while the Hisense U7KQ offers many features for gamers, certain key aspects, such as optimal VRR performance and support for HGIG, may not meet the expectations of more demanding users. Nevertheless, the TV still provides good support for most standard gaming features, making it a suitable choice for a wide range of gamers.

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.

The Hisense U7KQ TV features very low input lag across all picture modes, which is crucial for gamers who require quick screen response. Regardless of the signal type – whether it's 4K, Full HD, 60 Hz, or 120 Hz – the lag remains below 20 ms. This result is excellent and ensures that even the most demanding gamers will not experience any delays while playing. As a result, this TV deserves the highest rating for gaming performance.

The lag time of the TCL C855 is astonishingly low in every scenario. Even the most passionate gamers will surely appreciate the very low input lag at demanding 4K 120 Hz settings with HDR, clocking in at just 7 ms. Furthermore, the lag at these same settings, but with Dolby Vision HDR enabled, remains at the same level, which isn't so obvious with competing models. Therefore, the TCL C855 deserves the highest rating and recommendation.

The Hisense U7KQ television works excellently with a PC, thanks to several key features. First and foremost, it supports chroma 4:4:4, which is essential for displaying text and graphics in the highest quality without losing details. This ensures that images and texts are clear and sharp, which is particularly important for users who use the television as a monitor for work or gaming.

Additionally, the Hisense U7KQ features very low input lag in PC mode, meaning minimal delays between actions taken on the computer and the displayed image. This is crucial for gamers who need quick screen response to gain an edge in dynamic games. The low input lag ensures that every action is immediately reflected on the screen, enhancing the overall user experience.

Despite using a BGR pixel arrangement instead of the more traditional RGB layout, the readability of fonts on the screen is at a good level. BGR (Blue-Green-Red) is a configuration where the subpixels are arranged in a different order than in standard RGB. This can sometimes affect text quality, depending on the operating system settings.

In summary, the Hisense U7KQ is a good choice for PC users, offering support for chroma 4:4:4, low input lag, and good text readability, making it a versatile device for both work and entertainment.

TCL C855 when connected to a computer as a monitor performs very well. This is thanks to the very low latency between the mouse-eye-screen and the excellent readability of fonts, which comes from the proper 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 may not be able to adjust fonts to this subpixel layout. Additionally, the TV has minor issues displaying fonts on a black background, for which we deducted some points.

The screen uses a VA panel, which unfortunately has its limitations in terms of viewing angles. Unlike some competing models, Hisense U7KQ does not have any coatings to improve this aspect, which means that image quality significantly decreases when viewed at an angle.

With even a slight deviation from the central axis, one can notice that the contrast of the image begins to deteriorate. Details in the dark areas of the image become overly pronounced, and colour saturation diminishes. These effects are typical of VA panels, and in practice, this means that the best viewing experience can only be obtained when sitting directly in front of the screen.

For users who plan to watch the television from different spots in the room, this can be a significant limitation. Reduced image quality at an angle may affect overall satisfaction with the product, especially when watching movies or shows with a larger group.

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

TCL C855: 910 cd/m2

Hisense U7KQ: 966 cd/m2

Hisense U7KQ does not have the best reflection handling properties, as its panel is equipped with a satin finish, which is not as effective in reducing glare as the matte finishes used in some other TVs, nor does it maintain as deep a black as glossy panels. It is somewhere in between these two effects. Light reflections may be visible, especially in brightly lit rooms, which can affect viewing comfort.

However, the high peak brightness values that this model achieves effectively compensate for these limitations. Thanks to this brightness, the image remains clearly visible even in sunny rooms. This means the TV performs quite well in challenging lighting conditions where other models may struggle to provide adequate picture quality.

The glossy finish of the panel on the TCL C855 prevented it from achieving the highest rating for TV performance during daytime viewing, although it is precisely due to this that the blacks during the day are very good. Thanks to the high brightness in SDR content, the actress's face strongly stands out through reflections. However, a downside of the panel is that light hitting directly on the TV "spills" out rather than being contained in one spot. Generally speaking, if sunlight doesn't hit the panel, the TCL C855 will be a very good choice for brightly lit rooms.

Hisense uses the VIDAA operating system, which is a proprietary solution from this brand. Although it doesn't offer as much expansion and as many apps as the popular Android TV, it has its advantages. The VIDAA system runs quickly and stably, meaning that users don’t have to worry about freezes or long loading times for apps.

However, VIDAA does have some limitations. There are quite a few apps available, but unfortunately, it lacks music apps like Spotify or Tidal. Nevertheless, VIDAA supports most standard features that might be needed, such as screen mirroring, voice search in Polish, the ability to connect a keyboard and mouse, and Bluetooth headphones.

The television also supports many other features that are important to users, such as the ability to record programs to USB and schedule recordings. However, it lacks some specific functions like teletext or the "Audio Only" mode, which allows listening to audio with the screen off.

In summary, while the VIDAA system is lesser-known and has certain limitations compared to Android TV, it offers stable and fast performance and supports most features that users might need. It is a solid solution for those looking for a simple and effective operating system in a television.

TCL C855 operates on the Google TV system, which is a significant advantage compared to TVs equipped with proprietary systems from manufacturers, where installing applications from a USB drive can be challenging or often downright impossible. With Google TV, we have the option to install almost 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 significantly simplifies entering queries. Additionally, thanks to integration with Google, we can utilise voice control features using the remote, which works very well, although there can be minor issues with translating functions and options. It’s worth mentioning 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 off days, and sometimes it does have its "bad day".

In summary: Google TV is currently one of the most popular systems on the market. Thanks to its powerful CPU, it runs very smoothly, does not freeze, and has no issues with stuttering for a significant part of its usage. This is definitely the best option for those who want to make the most of the TCL C855 TV’s capabilities and appreciate the openness of the system.

The built-in media player on the Hisense U7KQ television handles most popular video formats well; however, there may occasionally be issues with loading subtitles, which can be frustrating for users who prefer watching films with text.

It is worth noting certain limitations regarding the support for less popular codecs, such as AV1 and H266. While these codecs are not yet widely used, their lack of support could pose a problem in the future when they become more common. Currently, however, most users will not feel their absence.

Strange behaviour has been observed when playing photos – some files in specific resolutions may not load correctly. This can be problematic for those wanting to browse their photographs directly from a USB stick. For this reason, viewing photos on this television may be limited, as some files may not load at all.

In summary, although the built-in media player on the Hisense U7KQ performs well with most standard video formats, users may encounter certain limitations related to loading subtitles and photos in specific resolutions. Issues with the support of less popular codecs are currently minimal but could become more significant in the future.

The default media player on the TCL C855 handles practically all the media we've prepared for it very well. Almost every video format is supported. However, an important downside may be the lack of a font colour change feature. There are hardly any issues with photos and their maximum resolution. It's definitely worth noting the absence of support for Apple's HEIC and SVG files. On the other hand, we can play audio files without any problems, and we don't think many of you are using AIFF or DSD64. One undeniable advantage of the C855 and its operating system is that at any time we can download another player from the app store that will play anything.

The Hisense U7KQ TV offers satisfactory sound quality, which is sufficient for most everyday uses. The sound system of this model features good volume and clarity, making dialogues and sound effects clear. However, the TV may not deliver the full audio experience that can be obtained from dedicated audio systems or soundbars. One of the main audio advantages of the U7KQ is its ability to reproduce sound with minimal distortion at higher volume levels reaching up to 83dB and support for Dolby Atmos and DTS.

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

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