Sony Bravia 9 (XR90) vs TCL C655 Pro

The results of brightness measurements on the Sony Bravia 9 are phenomenal. Each scene reaches well over 1500 nits, and when watching films, the television can sometimes shine even brighter. It goes without saying that such brightness allows for unprecedented experiences and engagement with video material at the highest possible quality. Thanks to the high coverage of the DCI-P3 colour palette, the image is full of colours and, combined with such high luminance, it practically breathes. With high peak brightness, viewers can enjoy the full range of colours even in the most challenging scenes, such as those based on dynamic lighting changes. The Bravia 9 offers support for Dolby Vision and HDR10 formats, which further enhances the viewing experience.

In the HDR effect quality category, the television TCL 655 PRO demonstrates decent capabilities, achieving a peak brightness of 550 nits. This allows for enjoyment of the HDR effects, which is particularly evident in scenes such as the first from the film Life of Pi or the last frame from The Meg. Nevertheless, the limited number of dimming zones causes some issues. While in bright scenes the television performs better than its lower model, in more demanding scenes, such as the second and fourth scenes from Sicario 2, it struggles. The dimming algorithm aims to achieve deep blacks, but at the cost of brightness – resulting in a drop in brightness of even half during those moments. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles more of an SDR. Regardless, the colour gamut coverage deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

The best factory mode in Sony televisions has consistently remained "IMAX Enhanced" for years. It was this mode that we used throughout the entire testing procedure. Although it is indeed the most similar to the standard compared to other predefined options, it has a number of aspects that can be improved to make viewing even more enjoyable. When we look at the gamma in SDR materials, we notice quite a significant boost that will be associated with image contrast. It is worth noting that the very beginning of the graph has an even greater rise compared to the reference, leading to a blending of details in the blacks, creating a uniform blot. The EOTF curve in HDR content looked quite correct and exhibited only minor deviations from the reference. However, a common feature for both was: a green colour dominance in white balance, issues with greys and overall colour misalignment. The aspect that stood out the most was related to the uneven distribution of hues in white balance. Due to the excess of the aforementioned colour, the image was covered with an unpleasant greenish tint.

Each of our television tests is conducted in film mode, which usually offers the best colour reproduction. Nonetheless, even this mode is not free from issues, as we noted in the model TCL 655 PRO.

In the case of HD content, the white balance distinctly shifts towards red, and this effect becomes particularly noticeable in a scene from Star Wars, where the white elements of the scenery take on a pink hue. For 4K HDR material, the situation is better, but there is a noticeable tendency to excessively emphasise the colour blue. As a result, the picture may appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristics also leave much to be desired. The Gamma graph indicates serious difficulties with excessive brightening, causing the overall presentation to appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we detailed in the paragraph concerning HDR effects.

The colour reproduction after the calibration process should be regarded as excellent. Regardless of the signal, whether SDR or HDR, we can expect an image that is remarkably close to what the film director saw. Virtually every flaw in the image has been modelled and maximally corrected. This was made possible thanks to the advanced tools used for the calibration process, which Sony has been providing in its televisions for years, including 2- and 20-point grey scale adjustment as well as a very comprehensive CMS.

After calibrating the television TCL 655 PRO, a noticeable improvement in white balance is evident, where the tendency for the screen to have an excessive pink hue has been completely eliminated, which was previously visible in the factory mode. The image has taken on more natural tones, especially in white and light elements, positively affecting the overall perception of the picture. Regarding brightness characteristics, the Gamma chart has also improved – the screen is no longer overly bright, which previously made the image appear washed out. However, there are still some issues with the EOTF curve, which are difficult to eliminate due to the design of the television and its limited number of backlight zones. These limitations prevent achieving perfect results in this regard. Nevertheless, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high picture quality and very good colour reproduction.

Let’s take another look at the quality of tonal transitions, but this time we will analyse the quality of image scaling, which will be significantly important when watching lower quality materials. For starters, we will take a look at the function responsible for the quality of tonal transitions. And while by default they are quite average, after activating the option, even at the lowest level, we can confidently say that these are among the best we have seen. You can confidently enable this feature, as it does not cause any negative phenomenon, such as film grain blurring.

Sony has been boasting for several years now that its "XR" processor is unmatched when it comes to image scaling. And we find it quite easy to believe, because in fact the image is extremely sharp, yet very natural.

The TCL 655 PRO television performs quite well with tonal transitions in lower quality materials. The "Gradual Smoothing" function at a low setting effectively smooths out tonal transitions, but this comes at the expense of losing some important details, such as the texture of objects. One positive aspect is that it does not negatively affect film grain, which helps maintain the natural appearance of the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a more vivid image. However, those who like a softer, subtler look may find this a drawback. Additionally, a downside is the cropping of the image due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - for example, news tickers.

The maximum refresh rate of the Sony Bravia 9 is 120 Hz. This is the essential minimum for watching primarily sports or materials with significant motion dynamics while maintaining a sharp and smooth image. For demanding users, the manufacturer has implemented a very comprehensive smoothing system, which has been divided into three segments: Smoothness (Film), Smoothness (Camera), and Clarity. The first two correspond to the degree of blurring and the degree of smoothing, respectively. The third option will be described in more detail below. Moreover, we can adjust all settings to various degrees, each of which will produce an effect, ensuring that we can find our own golden mean. In the picture, we present a setting with slight smoothing, without the soap opera effect.

The TCL C655 PRO television is equipped with a 4K panel with a refresh rate of 60 Hz, making it best suited for watching films. Additionally, the "Flicker Reduction" feature allows users to adjust the smoothness of the image, giving them the choice between a smoother motion and a cinematic, frame-by-frame effect. Moreover, the television performs well with lower resolution materials, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy a smoother picture at the expense of lower resolution.

The Sony Bravia 9 television is equipped with four HDMI ports. However, somewhat inexplicably for a device of this class, only two of them operate in the 2.1 standard. That said, it should not be overlooked that almost all functions perform excellently and do not cause any negative feelings when being activated. Games running either in HDR10 or Dolby Vision have very low input lag, allowing for a very comfortable session with the title. A consolation remains in the form of a good implementation of the HGIG mode, which, after proper adjustment, does not differ significantly from Dolby Vision.

A year ago, Sony added to its televisions what has long been a standard for some manufacturers. This refers, of course, to the GameBar, enabling quick adjustment of settings without the need to exit the game. The implementation of this feature was successful and works very efficiently. We have been provided with conveniences such as: a crosshair grid, black level correction, and the option to reduce the screen to the proportions of gaming monitors.

The Sony Bravia 9 will undoubtedly find its fan base, most likely among PlayStation enthusiasts. Here, we must admit that it will be the most sensible choice, as in practice both the console and the television possess exactly the same capabilities. Looking at the bigger picture, while overlooking the issues with Dolby Vision in games, one cannot detract from the fact that the Bravia 9 is a very good television in the context of gaming.

The TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all the key technologies that significantly enhance the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in improved responsiveness and minimal signal delay – particularly important in dynamic titles. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and thus guaranteeing smoother gameplay.

Support for Dolby Vision in gaming mode allows for more detailed colour and contrast reproduction in games that support this format, while the Game Bar provides quick access to essential settings such as response time and latency level. Unfortunately, the model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those willing to forgo 4K, support for Full HD and 2K at 120 Hz delivers exceptionally smooth visuals, presenting an attractive alternative for enthusiasts of higher refresh rates.
