Compare: Sony Bravia 7 (XR70) vs TCL C855

Testing the Sony Bravia 7 quickly revealed that this television is capable of quite a lot. Although it is the "lowest" model from the Japanese manufacturer in the new 2024 range, it certainly does not feel like a compromise. The picture impressed us with its depth of black and the detail in bright scenes – thanks to the Mini LED technology, which makes a difference. When playing films in Dolby Vision, it was immediately noticeable how much HDR adds life to every scene. The intense colours and excellent dynamics made watching evening screenings a true pleasure for us. Daily use of this television also pleasantly surprised us. The Google TV system worked flawlessly, and the choice of apps was extensive enough that we had no trouble finding everything we wanted to watch. The backlit remote is a small but practical addition – in the evenings, we greatly appreciated not having to fumble around for buttons. Older content that we watched gained quality thanks to the advanced image processing. When we checked the television for gaming, it also left a good impression on us. The 120 Hz refresh rate provided a smooth image, and the low input lag allowed us to enjoy fast and dynamic gameplay. We particularly liked the Game Bar feature – easy access to settings during gameplay is something every gaming enthusiast will appreciate. The television handled even more demanding titles excellently. However, not everything was perfect. Only two HDMI 2.1 ports, one of which is intended for eARC, may be an issue if someone plans to connect several devices simultaneously. Additionally, when we watched the television from an angle, we noticed that the picture quality was not as good as when viewed straight on – the lack of a layer to improve viewing angles was noticeable here. Nevertheless, the Bravia 7 is a television that pleasantly surprised us. It combines excellent picture quality with functionality that works well for both everyday use and during evening screenings or dynamic gameplay. The minor limitations are noticeable, but they do not overshadow the whole, which definitely deserves the attention of a buyer.

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 Sony BRAVIA 7 television with a VA panel and MiniLED backlighting technology offers excellent black quality. The tested 65-inch variant is equipped with 512 dimming zones, which allows for very good contrast, particularly in demanding movie scenes. Naturally, larger sizes of the television have more zones, positively impacting contrast and image depth. During testing, in scenes from the film "Oblivion," the BRAVIA 7 performed excellently in capturing dark and light areas, providing decent separation of lights (the light effect did not blur into a large spot) from deep black. However, as is often the case with televisions featuring local dimming, certain difficulties arise with small, bright light elements. In more demanding segments (e.g., scenes 4 and 5), it is noticeable that the television "struggles" to maintain high brightness of these elements, affecting the contrast – bright objects are either too dark (resulting in poor contrast) or a slight halo effect appears around them. In a scene from the film Sicario 2, the action of the zones can be seen, causing the aforementioned effect, but it is slight. Despite these minor imperfections, the overall impression is positive – the local dimming algorithm works really well, ensuring that the image maintains high contrast, and the quality of black and details is satisfying.

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.

Since we know that the television handles contrast well, let's check how it performs in terms of HDR effects. The luminance graph shows the very high capabilities of this model – 1500 nits is a truly impressive result. The HDR effects are particularly striking in scenes where most of the screen is covered in light, such as in scenes 1, 3, and 5 of the test. Minor shortcomings, typical of this technology, are still visible with very small light effects, as in the scene from the film "Sicario 2," where brightness drops to 500 nits. Although these are not stunning results, they can be considered decent. Additionally, it is worth praising the television for its high coverage of a wide colour gamut – DCI-P3 at 96%, which allows for vibrant, saturated colours.

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.

The IMAX Enhanced mode on the Sony BRAVIA 7 television is undoubtedly the best mode available on this model, although it is not without its flaws, as its name might suggest. The biggest issue is the white balance – both in HD and 4K HDR content, there is a clear dominance of red, which causes the image to take on pink hues. This is particularly noticeable on the tested snow pattern, where the pinkish tint becomes very apparent. Errors in the Colour Checker test also confirm these deviations – although they are not catastrophic, there is a tendency to drift towards warmer colours. As for brightness performance, the gamma remains at a decent level with a slight peak but without major issues. However, the biggest challenge comes from 4K materials. It is clear that the EOTF curve is significantly above the reference graph, which causes the image to become overly brightened.

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.

Sony BRAVIA XR70 offers a wide range of tools that allow for adjusting the picture to individual preferences, enabling us to make significant adjustments to the settings. The white balance has been free from the problem of red colour dominance – snow no longer takes on pink shades, which was previously noticeable. Although one can detect slight deviations in the final part of the white balance graph, concerning a drop in blue colour, they are acceptable and difficult to notice in everyday use. The Colour Checker test confirms that errors in colour reproduction are no longer as pronounced and rarely exceed a value of 2, which is a very good result. As for brightness, gamma, while not requiring much improvement, was slightly adjusted. The most significant change was noted in the EOTF curve – the television no longer has issues with excessively brightening the entire image in 4K material. However, upon closer analysis and the inclusion of EOTF characteristics in film material, some limitations of the television become apparent due to the previously discussed dimming algorithm. Some small elements may be slightly more brightened, but these errors are so minor that most users will not notice them. Overall, the calibration results are very, very positive.

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 Sony XR70 television handles gradation excellently. In the test sequence, only a few scenes exhibit slight issues with tonal transitions in dark areas; however, most of these problems disappear when the gentle gradation option is switched on. Generally speaking, the television offers great gradation that will satisfy even the most demanding users.

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.

Since we know that the television performs very well with high-quality materials, it is worth checking how it fares with lower-quality content. Here, the television shows its potential, and the applied graphics processor works really brilliantly. On the test screen with the light bulb, there are no issues with colour transitions, and the smooth gradation feature works very well – we recommend setting it to "Medium".

As for digital processing, or so-called upscaling, the television sharpens the image quite noticeably, which leads to slight aliasing, for example, on the branches in the background, but it does not remove desirable details. Nevertheless, the overall appearance is really appealing and may be to the taste of most users. However, if we prefer a softer, more plastic image, this effect can be reduced in the settings by adjusting the sharpening level according to personal preferences.

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

Image scaling in TCL C855 is described as one of the best we have had the opportunity to test so far. The image is sharp, but in a way that could be described as natural for our eyes. Even the small, fine branches do not have jagged edges, and there is no white halo around figures, which is characteristic of inferior scaling systems.

The Sony BRAVIA 7 television with a 120 Hz display will satisfy most users in terms of motion smoothness. Additionally, Sony offers the Motion Flow feature, which allows for the selection of three different picture settings, tailoring them to individual preferences: Smoothness – Film: This setting enhances motion smoothness, giving the image a more cinematic or theatrical quality. Smoothness – Camera: This setting provides even greater smoothness, useful when watching dynamic scenes such as sports broadcasts. Clarity: This setting focuses on minimising noise and motion artifacts, resulting in a more stable and clear image.

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.

Sony Bravia 7 has significantly improved its capabilities for working with consoles compared to earlier models. The television supports variable refresh rate (VRR), which eliminates the tearing effect, and is compatible with graphics cards, ensuring smooth display. The auto low latency mode (ALLM) effectively reduces input lag, which is crucial in dynamic games. Dolby Vision with low latency additionally provides impressive HDR effects that look great during gameplay.

Sony Bravia 7 also offers a Game Bar feature, which allows quick access to settings and monitoring parameters while gaming. An interesting option is the ability to enable a virtual on-screen crosshair, which can provide a slight advantage in shooter games. Nevertheless, compared to the Bravia 9 model, the HGIG feature in the Bravia 7 does not perform as well, which may be noticeable for more demanding gamers – especially as the HGIG mode is becoming increasingly popular among players as the preferred method for reproducing HDR effects.

A drawback is the lack of support for 1440p@120 Hz resolution, which could make gaming easier for users with less powerful graphics cards. Furthermore, the Sony Bravia 7 is equipped with two HDMI 2.1 ports, one of which is often used to connect an audio system via eARC, limiting the available connections for new generation consoles.

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.

Sony BRAVIA 7 delivers exceptional results in terms of input lag, particularly with 120 Hz content, where the delay is around 11 ms – this is an excellent result that will satisfy even the most demanding gamers. The Dolby Vision mode also deserves recognition, as it is usually associated with higher input lag, but here it works really well, providing a comfortable gaming experience. However, we deducted 0.3 points for the results above 20 ms for 60 Hz content, although we believe that for most users, this difference is more of a placebo effect.

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.

The Sony BRAVIA 7 TV performs well when working with a computer, providing clear and readable fonts. An input lag of 11 ms is also an excellent result that will satisfy users using the TV for gaming and work. However, it should be noted that in the case of grey letters, a slight fading of some pixels can be observed, which somewhat deteriorates the readability of darker fonts, for which we deducted a few points.

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

The Sony BRAVIA 7 television has poor viewing angles, which is characteristic of VA matrices. The picture quickly loses quality when viewed from a greater angle – colours become washed out and contrast decreases. Considering the price of the device, it is a pity that a coating was not applied to extend the viewing angles, which would certainly improve the watching comfort from different spots in the room.

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.

BRAVIA 7 performs excellently when watching in bright environments. The satin coating effectively reduces reflections while simultaneously minimising the blurring of elements to the sides, resulting in very good visibility during the day. A brightness level of 1000 cd/m² in SDR mode is astonishing and ensures that the image remains sharp even in heavily lit rooms.

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.

Sony Bravia 7 runs on the Google TV system, which offers an intuitive and quick interface, allowing easy access to a multitude of applications. Google Assistant supports the Polish language, making the use of the television even more convenient and personalised. The interface is clear, and access to features and applications is quick and trouble-free. It is worth mentioning the remote control, which is charged via a USB-C port. Additionally, the remote is backlit, which significantly facilitates its use at night.

Sony Bravia 7 offers wide-ranging capabilities that will satisfy most users. The ability to record programmes and easily connect devices via Bluetooth are significant pluses. Unfortunately, it lacks the Picture-in-Picture (PiP) feature, which could prove useful for watching two sources of video simultaneously.

XR70 stands out with its practical and elegant design. The television is equipped with a 4-position stand, allowing it to be adapted to various spaces and settings – this is particularly useful when we seek flexibility in interior arrangement. Additionally, the slim aluminium frame gives the device a modern and stylish appearance. Although it is not as slim as some competitive Korean models, it still looks very attractive and solid.

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.

The built-in player handles most popular video and audio formats, allowing you to enjoy a wide range of content without any issues. Although there are slight shortcomings when playing photos, thanks to the Google TV system, you can easily install other applications that effectively solve this problem and expand the multimedia capabilities of the television.

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.

Although the Sony Bravia 7 television is equipped with only a 2-channel speaker system (2.0), there are two speakers per channel with a total power of 40 W. As a result, the sound quality is really good, and the bass is noticeable, making watching movies and listening to music more enjoyable.

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.
