Compare TCL C855 vs Sony X85L

The TCL C855 is a standout television in the TV market, showcasing a versatile performance across various applications and excelling in its price range. With Mini LED backlighting, the TV achieves impressive contrast and black levels, resulting in deep, vivid images. Its algorithm effectively maintains black uniformity, minimizing blooming effects, a significant advantage for viewing HDR content.

While the TCL C855 can reach brightness levels of up to 1800 nits, which is commendable, it is worth noting that brightness can significantly drop to around 200 nits when bright but small elements appear on-screen. Additionally, the mid-tone boost can compromise contrast and reduce fidelity to the director's original vision.

For gamers, the TCL C855 shines brightly, offering extremely low latency and high-quality performance thanks to its full implementation of HDMI 2.1 features. The inclusion of the Google TV operating system adds to its appeal, providing nearly limitless options for application installation, including support for APK files from outside the official store.

The TCL C855 is an excellent choice for those seeking a reliable and versatile television. While it may have some drawbacks, its overall image quality, gaming performance, and advanced operating system make it a strong contender in the market.

Sony X85L is a model from 2023 that will continue to be offered in 2024 by the Japanese manufacturer. Its biggest advantage is the Google TV system. It currently provides the greatest access to applications, so we don't have to fear that any of our favorite apps will be missing. The intuitive interface and voice control feature via Google Assistant make daily use of the television convenient and modern. In terms of picture quality, Sony X85L performs well. Thanks to local dimming (albeit with a very average number of zones), black looks really decent. Additionally, its quite high brightness allows for comfortable TV viewing during the day, even in well-lit rooms. Moreover, the television offers the ability to record programs from built-in tuners, which is a great convenience for those wanting to control what and when they watch. In terms of motion fluidity, the X85L also does not disappoint. The 120 Hz panel and Motionflow system provide smooth display of dynamic scenes, pleasing both movie buffs and sports fans. The TV is also equipped with a range of features for gamers, including VRR, Game Bar, and G-Sync support, making it an attractive choice for gaming enthusiasts. Of course, the television is not without its drawbacks. The lack of HGiG support and high input lag in Dolby Vision mode can be disappointing for more demanding gamers. Additionally, the compromise between font readability and image fluidity when connected to a PC may not appeal to everyone. Nevertheless, Sony X85L is decent equipment, particularly worth noting if it can be purchased on promotion.

The TCL C855 features a high-contrast VA matrix, achieving an impressive ANSI contrast ratio of 5238:1 without dimming. This level allows for very good black levels. Furthermore, the panel incorporates multi-zone Mini LED backlighting, divided into 1344 independent dimming zones for the 65-inch model. Such a configuration yields excellent results in our tests. Notably, TCL is among the few manufacturers offering such advanced panel specifications at a reasonable price, unlike the traditional big four brands. In the majority of scenes we evaluated, the performance was impressive, particularly in the first three tests; even in the third, with a ratio of 54,000:1, the black level and contrast were far from weak, demonstrating satisfactory results. However, performance does dip in two specific scenarios: scenes with movie strips and when the screen contains many elements surrounded by black. While the last test scene maintained excellent contrast, the final scenario revealed some blooming in the blacks. A frame from the movie "Oblivion" showcased the TCL C855's capabilities, with black levels that can rival those of OLED screens—a notable achievement. The television also demonstrates commendable light separation, which is no small feat. In our flagship scene from "Sicario 2" the contrast was equally impressive, although some loss of detail in the blacks across the first, second, and third planes was evident. The backlight control algorithm effectively minimizes halo and blooming effects, which is praiseworthy. However, it's important to note that very small elements, like stars, can occasionally be completely dimmed by the TCL C855.

The Sony X85L TV is equipped with a VA panel, which in itself offers quite good contrast. Additionally, this model features local dimming technology – in the 55-inch version, it includes 24 zones. Although this number is not impressive, it naturally increases with the size of the TV. The contrast in the X85L is good, though not the best, especially in comparison to other TVs also equipped with advanced local dimming technology. Results at the level of 8000:1 are satisfactory, but they appear average against the competition. In some cases, such as the third scene from the movie Arrival, the contrast is promising and performs quite well. This is thanks to the very good dimming algorithm that Sony has been using in its TVs for years. Unfortunately, due to the limited number of local dimming zones, the TV suffers from noticeable blooming, which can be seen, for example, in scenes with the helicopter from the movie Sicario 2.

The TCL C855 delivers a highly varied HDR effect. At times, the television truly excels, while at other moments, it appears reminiscent of a low-end model equipped with FALD backlighting. Inconsistency is frequently found with this brand, so it didn’t come as a surprise. The first and last scenes, which feature large light elements, are nothing short of spectacular, boasting brightness levels of 1470 and 1820 nits, respectively. Such brightness can make viewers squint their eyes, allowing them to feel the extraordinary dynamism of the scene. It genuinely immerses the audience, creating a sensation of being inside the movie itself. However, the situation shifts dramatically when small or subtle elements with high luminance appear against a dark background. In these instances, the TCL C855 significantly reduces brightness to levels as low as 240 nits to mitigate halo effects. This reduction is disappointing, as it can make the movie appear as if it was not filmed in HDR. Despite these shortcomings, the HDR effect on the TCL C855 enhances the viewing experience during dynamic scenes, making it feel more engaging and allowing the viewer to feel part of the action. Even with smaller high-luminance elements, the television retains details without excessive dimming. Additionally, the TCL C855 adjusts image brightness according to scenes with rich detail, further enhancing viewing comfort.

The Sony X85L TV offers solid HDR performance with a brightness level of 750 nits, which is sufficient to enjoy vivid effects. In scenes of moderate difficulty, such as the first, third, or fifth test scenes, a brightness of around 600 nits allows one to fully experience the HDR effect. Unfortunately, in more demanding segments, such as the scene from the movie Sicario 2, the TV shows its limitations. Drops in brightness to 250 nits make the HDR effect lose its impressive quality and resemble regular SDR instead. Nevertheless, it is worth highlighting the very good coverage of the DCI-P3 color palette at 95%, which definitely deserves praise and positively affects the overall image quality.

The best factory mode for the TCL C855 is the "Film" setting, and all our tests were conducted using this mode. However, like many predefined modes, it has flaws that should be addressed to achieve an image closer to the producer's original vision. In our examination of the colour characteristics for both SDR and HDR materials, issues were found.

Focusing first on SDR content, there is a noticeable dominance of green in the white balance, which leads to an unpleasant greenish tint across the entire image. The gamma chart, crucial for image contrast, shows a significant deviation from the reference line marked at 2.4. Initially, there is a pronounced spike in the measured value, resulting in an over-contrasted image where details can merge into a dark blob. This condition persists for nearly 20% of the chart before it dips below the reference line, causing the image to brighten and resulting in a substantial drop in contrast.

In HDR materials, the factory mode performs somewhat better; the white balance appears more balanced overall, although the green tint resurfaces in the latter half of the spectrum. When we look at the Electro-Optical Transfer Function (EOTF) curve—unlike gamma, which reflects contrast—we identify two main errors: the darkest scenes are too dark, while the brightest ones become overexposed. This discrepancy was evident in our review of the scene from the movie "Pan," further illustrating the TCL C855's HDR performance issues.

The Sony X85L television was tested in IMAX Enhanced mode, which, although associated with world-class cinema, does not guarantee an image that aligns with the director's vision. The main issue is the white balance – there is a noticeable strong dominance of blue color and significant lack of red. As a result, the image becomes unnaturally cool and appears artificial. The color reproduction errors were confirmed by the Colour Checker test, which showed significant discrepancies – colors were "scattered" like shots from a rifle, and only a few samples hit the target values. This clearly shows that the precision of color reproduction leaves much to be desired.

The brightness of the image is one of the positive features of the TV. The gamma for HD content is at an acceptable level, although there are minor errors, but generally, it is quite good. However, the brightness characteristics for 4K materials remain an issue, controlled by the EOTF curve. It is evident that very small, bright elements of the image are too dim, which is a result of the limited number of dimming zones due to the design of the television.

TCL, like most manufacturers, offers advanced calibration tools within its televisions. These include both 2-point and 20-point adjustments for grayscale, as well as a comprehensive colour management system. As a result, we achieved impressive results in SDR materials, bringing the image significantly closer to the reference standard. We successfully eliminated both the green tint and the gamma issue, although a slight "kink" at the very beginning of the gamma curve still persists.

In contrast, the situation with HDR materials was less favourable, as the TCL C855 did not allow for precise modelling. We were only able to make minor adjustments to the EOTF curve while significantly enhancing the overall colour accuracy. This limitation suggests that while calibration tools are effective, they may require further refinement for optimal HDR performance.

Thanks to the use of calibration tools offered by Sony X85L, the image quality has been significantly improved. After calibration, the white balance for HD content is much more stable, making colors look more natural and the image gains authenticity. Although it is not perfect, these changes allow viewers to enjoy a more realistic representation of colors, eliminating the earlier cool tone. The gamma, which already performed decently, has been adjusted to an even better version. As a result, tonal transitions and brightness are more consistent, positively affecting the depth and detail of the image.

As for 4K content, despite efforts, the white balance still struggles with a deficiency of red, which can result in overly warm colors in some scenes. Synthetic tests showed that the EOTF curve in HDR is quite stable, with a slight boost in mid-bright scenes. However, in real film materials, the TV can still be too bright with fine, light details, which is a result of the limitations of large local dimming technology.

Nonetheless, calibration has brought significant benefits, particularly in color accuracy, improving overall image quality and providing a more natural and cohesive directorial vision.

Another important aspect of assessing image quality is tonal transitions. To achieve a clean image free from posterisation effects, a television must employ highly effective algorithms for smoothing colour gradations. We must acknowledge that the algorithm used in the TCL C855, known as "Gradual Smoothing," ranks among the best we've had the opportunity to test. In nearly every scene, the performance is impressive, leaving little room for criticism. A prime example of this capability is the scene from "The Green Knight," which poses a challenge due to the multitude of fine and subtle transitions in the fog. The C855 successfully smooths out the details within this scene, allowing the viewer to fully appreciate its suspenseful atmosphere. The only instance where slight posterization is noticeable occurs in a frame from "The Green Knight," where the reds in the upper left part of the screen create a contrasting effect.

The fluidity of tonal transitions in the Sony X85L is at a good level – the color gradation is smooth, even in more demanding areas, which makes the perception of scenes positive and natural. The biggest problems occur in the shadow areas, where subtle color blends may be visible. Nevertheless, the television performs well enough that most viewers should not notice these minor imperfections.

Once again, we will take a 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 television programs or older films. We will focus on the function responsible for tonal transitions. Interestingly, just like in the scenes from the previous test where it performed excellently and smoothed out practically all the inconsistencies, here it had issues. Using the menu responsible for the operation of this function, we found that no setting—even the strongest—was helpful.

Image scaling in TCL C855 is defined 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 edges, and there is no white halo around figures, a characteristic of weaker scaling systems.

In terms of smoothing tonal transitions, the Sony X85L television does not offer any dedicated enhancement options, which is a downside. On the other hand, image scaling performs quite well – the television adds a bit of artificial sharpness, which can make details such as tree branches more pronounced, although sometimes with noticeable jaggedness. This type of effect may appeal to some viewers who prefer a more detailed image.

The maximum refresh rate you can set on the TCL C855 is 144 Hz. Naturally, this is only possible after connecting the TCL C855 TV to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we want to watch primarily sports or materials with a lot of motion dynamics. For those who require high image fluidity, the manufacturer has implemented a multi-stage motion smoother. It is divided into two separate sliders which control the sharpness of moving images (Motion Blur Reduction) and flicker (Flicker Reduction). Both sliders can be adjusted from 0 to 10, with each level affecting the degree of fluidity, so everyone can find their sweet spot. We present a setting that allows for slight smoothing without the soap opera effect. The matrix of the TCL C855 features a very good response time. This is particularly important since VA panels often struggle with the so-called ghosting effect, where a black halo can be observed behind a fast-moving object. where a black halo can be observed behind a fast-moving object.

The Sony X85L, equipped with a 120 Hz panel, will meet the expectations of a wide range of users – from sports and gaming fans to movie buffs. Movie enthusiasts will surely appreciate the presence of one of the best motion smoothing systems, Motionflow. This system offers adjustment via smoothness and clarity sliders – smoothness is responsible for motion fluidity, eliminating stutter, while clarity enhances the sharpness of fast scenes, reducing blur.

The TCL C855 TV has fully-featured HDMI 2.1 ports, boasting a full bandwidth of 48 Gb/s. During our testing, we confirmed the seamless operation of all functions included in this connection standard. As highlighted, all checkboxes are illuminated in green, a feature that will undoubtedly be appreciated by gamers, whether on consoles or those using the TV 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. Those with powerful configurations can feed a 144 Hz signal to the C855, which handles this effortlessly. It is also worth noting the implementation of the HGIG mode, which can be excessively bright due to the shortcomings of the "Game" mode, making proper configuration on the screen challenging. Fortunately, the TV excels with the Dolby Vision format.

TCL, as one of the pioneering manufacturers, has equipped its televisions with a special GameBar, allowing for extensive adjustment of settings "on the fly" without the need to exit the game. This feature includes options like an additional crosshair grid, black level correction, and settings designed for individuals with disabilities. The image showcases the next generation of this solution.

In summary, the TCL C855 TV is an ideal choice for those seeking a screen for all forms of electronic gaming. With comprehensive features supporting such entertainment, it provides an extremely engaging experience. It is also important to emphasise that it maintains very low input lag, regardless of the selected settings, including when using the Dolby Vision HDR format.

Sony X85L offers quite a solid set of features for gamers, making it an attractive choice for gaming enthusiasts. First and foremost, the TV has a 120 Hz panel, translating to smooth and dynamic image display, ideal for both fast-paced action games and more demanding sports titles. It is equipped with two HDMI 2.1 ports with full bandwidth of 48 Gb/s, allowing for the full utilization of next-gen console capabilities. Additionally, the Sony X85L supports VRR (Variable Refresh Rate) technology, which helps reduce stuttering and artifacts during gameplay, providing a fluid experience. The TV also supports G-Sync, which is particularly beneficial for gamers using NVIDIA graphics cards, allowing for screen refresh rate synchronization with GPU performance, eliminating the tearing effect. It is worth mentioning the Game Bar feature, which facilitates quick access to essential gaming-related settings such as VRR, brightness levels, and display modes, making it convenient and useful during gameplay.

However, there are certain limitations. The TV does not support HGiG, which may be a downside for some gamers, as HGiG optimizes HDR effect rendering in games, providing a more authentic visual experience. Additionally, while Dolby Vision mode is available, it is not practical for gaming due to very high input lag.

The input lag of the TCL C855 is impressively low across all scenarios. Even the most dedicated gamers will appreciate the minimal input lag of just 7 ms at demanding 4K 120 Hz settings with HDR. Furthermore, this lag remains consistent when enabling Dolby Vision HDR, which is not always the case with competing models. As such, the TCL C855 merits the highest rating and recommendation.

In general, the input lag on the Sony X85L is very good, which is crucial for smooth gameplay and quick reactions in games. In standard modes, especially when using HDMI 2.1 and playing in 4K resolution at 120 Hz, the input lag is minimal.

Unfortunately, the Dolby Vision mode is an exception to this rule. In this case, the input lag reaches as much as 95 ms. Such a high level of latency makes the Dolby Vision mode practically unplayable, as reactions to commands are noticeably delayed.

When connected to a computer as a monitor, the TCL C855 performs exceptionally well. This is largely due to its very low latency time along the mouse-eye-screen line and excellent font readability, achieved through a chroma 4:4:4 at all resolutions, including 4K@144Hz.

The subpixel layout is BGR, which does not negatively affect usage in the Windows environment. However, this situation may change when using macOS or other software that cannot adjust fonts to accommodate this subpixel layout.

The cooperation of the Sony X85L television with a PC is a bit of a balance between image quality and user comfort. If we want to use the television for work, where clear text is important, we need to set the refresh rate to 60 Hz. In this mode, text looks good and does not strain the eyes, which is crucial if we plan to spend a long time in front of the screen.

On the other hand, if the television is to be used for gaming, where we can take full advantage of its capabilities at 120 Hz, we must take into account that the readability of fonts decreases significantly. The image becomes less sharp and the text harder to read, which can be frustrating. In short – the Sony X85L will work well for occasional connection to a computer, but if we need it daily for work and gaming, this compromise may not be to everyone's liking.

A well-known drawback of VA panels without an angle coating is their poor performance regarding viewing angles. This holds true for the TCL C855, where even a slight deviation from the central axis results in noticeable image fading and colour degradation.

The viewing angles on the Sony X85L, as is typical with VA panels, are not the best. The image looks great when viewed straight on, but just shifting to the side reveals that colors lose their intensity and contrast noticeably weakens. This can be a problem if the TV is intended for watching with a larger group, where viewers are seated at different angles. For those who usually watch solo or from one central spot, this won't be a big downside, but when viewing from the side, the picture quality unfortunately decreases.

The glossy finish of the TCL C855 panel prevents it from achieving the highest rating for daytime viewing performance. However, this finish contributes to impressive black levels during the day. The high brightness in SDR material makes the actress's face stand out prominently against reflections. A downside of this panel is that light falling directly on the screen tends to "spill" rather than being contained in one area. Generally speaking, if sunlight does not directly hit the panel, the TCL C855 remains a solid choice for well-lit rooms.

The performance of the Sony X85L TV during the day is quite decent. Its satin screen coating handles light reflection moderately well, meaning that in bright rooms, there may be reflections, but they are not bothersome enough to significantly interfere. The brightness in SDR mode at 570 nits is sufficient for comfortable TV watching during the day, even with natural light coming through the windows. This ensures that colors remain vivid and the image is clearly visible, making the TV effective for everyday use.

The TCL C855 operates on the Google TV platform, which offers a significant advantage over TVs with proprietary systems from other manufacturers, where installing applications from a USB drive can often be challenging or impossible. With Google TV, users can install virtually any application, whether from the official store or directly from online repositories via APK files.

This system also provides various conveniences in terms of control. Users can connect a keyboard with a touchpad, making it easier to enter queries. Additionally, thanks to integration with Google, voice control features via the remote work very well, although minor issues may occasionally arise with function translations. It's worth noting that Google TV regularly receives updates that enhance functionality and introduce new options. However, according to reports from users of older models, the software can sometimes have its off days, leading to occasional performance hiccups.

In summary, Google TV is currently one of the most popular systems on the market. Thanks to its efficient CPU, it runs very smoothly, avoiding freezing and stuttering for the majority of usage. This makes it an excellent choice for those looking to fully utilise the capabilities of the TCL C855 and who appreciate the openness of the system.

The Sony X85L operates on the Google TV system, which is a significant advantage for many users. The television offers wide access to applications, and using streaming platforms is smooth and user-friendly. The interface is intuitive and easy to master, allowing for quick switching between apps and searching for favorite content. Google TV allows for personalization of the home screen, enabling each user to customize it according to their preferences. Google Assistant further enhances the experience by offering voice control and quick adjustments of settings or movie searches without the need for a remote.

In terms of user functionality, the Sony X85L offers many useful options. The television has the capability to record programs, which is a significant convenience for those who want to watch their favorite content at any time. AirPlay support allows for seamless streaming of content from Apple devices, which iPhone and iPad owners will appreciate. Additionally, thanks to built-in Bluetooth, various devices such as headphones or keyboards can be connected. However, one drawback is the lack of a PiP (picture-in-picture) function, which may disappoint users who prefer multitasking on the screen.

The design of the Sony X85L television, while it may not be the thinnest, is solid and elegant. The metal base with adjustable legs is one of its strong points, allowing for height and width adjustments of the television to fit different furniture and spaces. This practical solution enhances the interior and adds a modern character to it.

The default file player on the TCL C855 performs admirably with nearly all the media formats tested. Most video formats are supported, providing a versatile viewing experience. However, a notable drawback is the lack of functionality to change font colours. When it comes to photo playback, the TV handles high-resolution images well, but it is worth mentioning that it does not support Apple's HEIC or SVG file formats.

On the audio front, the TCL C855 manages to play various audio files without any issues, although it's unlikely that many users are reliant on formats like AIFF or DSD64. A significant advantage of the C855, alongside its operating system, is the ability to download alternative media players from the app store, ensuring compatibility with a wider range of file types.

Sony X85L has no problem playing most popular file formats from USB, which is a big plus for those who often reach for external content. However, it is worth mentioning a small downside – the built-in player does not allow changing the font color in subtitles, which can be bothersome for some. Fortunately, thanks to the advanced Google TV system, users have a wide range of options. It is easy to install alternative media players that offer more customization options.

When evaluating the sound quality of the TCL C855, several key aspects come into play, such as clarity, balance, and the absence of dominant frequencies. In this case, the sound performance is commendable; it is well-balanced and does not evoke any negative sensations, providing an overall good audio experience.

For those who utilise a home theatre system, the TCL C855 supports a wide range of audio codecs, including the two most significant ones: DTS-HD Master Audio and Dolby Atmos. This support ensures high sound quality, making it a suitable choice for users seeking an enhanced audio experience.

The sound on the Sony X85L is good – it is clear across the entire scale, allowing you to enjoy both dialogues and music. The bass, although light, is perceptible and adds some depth to the overall sound. However, it should be emphasized that this is a subjective assessment – some will be satisfied with such a sound profile, while others may need additional audio equipment to fully feel the stronger tones and more spacious sound.
