Sony Bravia 9 (XR90) vs TCL C655 / C69B (55"-85")

The brightness measurement results on the Sony Bravia 9 are phenomenal. Each scene achieves well over 1500 nits, and while watching movies, the TV 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. With a high coverage of the DCI-P3 colour gamut, the image is full of colours and, combined with such high luminance, it practically breathes. Thanks to the high peak brightness, viewers can enjoy the full spectrum of colours even in the most difficult scenes, such as those based on dynamic lighting changes. The Bravia 9 supports Dolby Vision and HDR10 formats, which further enhances the viewing experience.

Overall, the quality of the HDR effect in TCL C655 / C69B looks quite promising. The average value in the test patterns is around 450 nits, which already allows you to feel the light effects and better image dynamics. However, as mentioned earlier, this effect may be somewhat subdued by slight differences in bright and dark shades, resulting from the lack of local dimming technology. However, the DCI-P3 colour gamut coverage of 94% deserves high praise, and this is possible due to the use of a quantum dot (QLED) panel. This makes the colours vibrant and well-reproduced when watching HDR content.

The best factory mode on Sony televisions has remained "IMAX Enhanced" for years. This is what we used throughout the entire testing procedure. Despite being the closest to the reference 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 is related to over-contrasting the image. It is worth noting that the very beginning of the graph has an even greater spike compared to the reference, which leads to the merging of details in the blacks, creating a uniform blob. The EOTF curve in HDR content looked quite accurate and only showed slight deviations from the reference. However, a common characteristic for both was: a greenish tint in the white balance, issues with greys, and general colour misalignment. The most noticeable issue was related to the uneven distribution of colours in the white balance. Due to the excess of the aforementioned colour, the image was covered with an unpleasant greenish tint.

The TCL C655 / C69B television offers a film mode that has been tested for colour reproduction quality. Although this mode is called film mode, it unfortunately has quite a few errors that the director would certainly not want to see when filming their work. Starting with image analysis, it's worth looking at the white balance – both in HD content and 4K HDR, the white balance has significant issues. In both cases, the red colour dominates, resulting in colours that are too warm, with an overall pink or yellow tint. This can be seen in the image below from the film "Star Wars." The Colour Checker test confirms these errors – the colour samples stray into incorrect shades, affecting the overall colour fidelity. The brightness characteristics are a lesser issue. However, they are not without flaws either. The gamma chart shows a strong spike at the beginning, which can cause the image to be overly bright, and the EOTF curve responsible for brightness in 4K HDR content also has significant fluctuations – it's evident how the television tries to maintain appropriate brightness, but it doesn't always succeed effectively.

The colour reproduction after the calibration process should be regarded as excellent. Regardless of the signal, whether it's SDR or HDR, we can expect an image incredibly close to what the film director saw. Practically every image flaw has been modelled and maximally improved. This was made possible by the advanced tools used for the calibration process, which Sony has provided in its televisions for years, including 2- and 20-point grey scale adjustment and a very elaborate CMS.

After calibrating the movie mode of the television TCL C655 / C69B , the white balance has been adjusted, and the colours look as they should – which is confirmed by only slight deviations in the Colour Checker test. The gamma is really good, which ensures that the television shouldn't have any issues with brightness in low-resolution material. Unfortunately, a similar EOTF characteristic is still noticeable, which is a natural occurrence in televisions that do not have local dimming – they simply struggle to "shine" brighter in a given part of the screen. Despite this design limitation, which cannot be bypassed, we recommend making adjustments in the settings, as the overall colour presentation looks really very good.

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 crucial when watching lower quality materials. We'll start with the function responsible for the quality of tonal transitions. While they are quite average by default, after activating the option, even at the smallest degree, we can confidently say that these are some of the better ones we've seen. You can confidently enable this function, as it does not cause any negative phenomena, such as grain blur.

Sony has been boasting for several years that its "XR" processor is unmatched when it comes to image scaling. And it's not hard for us to believe that, because the image is indeed incredibly sharp, yet very natural.

Television TCL C655 / C69B handles tonal transitions in low-quality materials fairly well. The "Gradual Smoothing" feature on low settings effectively smooths out tonal transitions, but it also blurs important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps to maintain the natural look of the image. In terms of digital processing, the television adds artificial sharpness, which some users who prefer a sharper image might appreciate. However, for those who prefer a softer look, this may be a drawback. Another downside is that the image has been significantly cropped due to the so-called overscan, which reduces the field of view and cuts off the edges of the image.

The maximum refresh rate of the Sony Bravia 9 is 120 Hz. This is the essential minimum for watching primarily sports or content that has a lot of movement dynamics while maintaining a sharp and smooth image. For demanding users, the manufacturer has implemented a very advanced smoothing system, which is divided into three segments: Smoothness (Film), Smoothness (Camera), and Clarity. The first two correspond to: blur degree and smoothing degree, respectively. The third option will be described in more detail below. Additionally, we can adjust all settings to various levels, each of which will have an effect, ensuring that we can find our very own sweet spot. In the photo, we present a setting with slight smoothing, without the soap opera effect.

The television C655 / C69B is equipped with a 4K@60 Hz panel, which means it's best suited for watching movies and less dynamic content. It also features a "Flicker Reduction" function, allowing users to adjust the smoothness of the image – they can choose whether they prefer smoother motion or a more cinematic, frame-like effect. The television can also adapt to lower resolutions, such as Full HD and 2K at 120 Hz, which will surely please gamers by offering a smoother image at the cost of resolution. It’s worth noting that this feature is available in sizes starting from 55"+. Additionally, the largest variant, 98", is equipped with a 144Hz panel with full motion smoothing.

The Sony Bravia 9 television is equipped with four HDMI ports. However, somewhat incomprehensibly for this class of device, only two of them operate in the 2.1 standard. Nevertheless, it shouldn't be taken away that almost all features work excellently and do not cause any negative feelings upon being activated. Games operating in either HDR10 or Dolby Vision have a very short input lag, allowing for a very comfortable session with the title. A consolation remains in the good implementation of the HGIG mode, which after proper tuning does not deviate significantly from Dolby Vision.

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

Sony Bravia 9 will certainly find its group of fans, most likely among PlayStation enthusiasts. Here, we must admit that this will be the most sensible choice, as in practice both the console and the television have exactly the same capabilities. However, looking more broadly, aside from issues with Dolby Vision in games, one cannot deny that the Bravia 9 is a very good television in the context of gaming.

The TCL C655 / C69B TV offers an almost perfect set of features for gamers, supporting all the key technologies. It has an ALLM feature that automatically switches the TV to low latency mode, significantly improving responsiveness and minimising signal lag, which is especially important during dynamic gameplay. The VRR feature allows synchronisation of the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay.

The TV also supports Dolby Vision in gaming mode, ensuring better colour and contrast reproduction in games that support this format, and the Game Bar enables quick access to gameplay-related settings, such as response time, latency level, and other parameters. Unfortunately, the C655 / C69B does not support 4K resolution at 120 Hz (the 98" variant is the exception), which may be disappointing for more demanding gamers seeking the ultimate smoothness in high-resolution games. However, if we can forgo 4K, the TV offers support for Full HD and 2K at 120 Hz, providing a smoother image and serving as a great alternative for those who prefer higher refresh rates at the expense of resolution.
