Sony Bravia 9 (XR90) vs TCL C6KS / C69KS / Q6CS

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.

And what about HDR? Here the C6KS performs quite well and – as is becoming the theme of this review – just like in the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect and generally, video materials look good here. However, it's important to keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g. stars) appear on a dark background, the television can quite significantly dim them. The goal is simple: to eliminate blooming and maintain the best possible black. It's a reasonable compromise. Most viewers will definitely appreciate deep, “true black” more than additional microscopic details, the display of which could cause the screen to appear greyed out. Such is the nature of local dimming technology in this price range, and one must be aware of this. It’s also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the QLED technology slogan. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92%.

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.

In contrast to the more expensive C6K model, in the tested C6KS we don't find an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests showed that in practice, in terms of colour reproduction, the lack of this specific label makes virtually no difference. The best available Film/Cinema mode here offers an almost identical picture profile to the aforementioned Filmmaker in the more expensive model. So we get a very similar image, just under a different name. Therefore, if you were wondering whether paying extra for the C6K would give you better colours – the answer is: no, in both cases the base is the same and requires slight adjustments.

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.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, leading to a very good final effect. After calibration, we will no longer see excessive warmth in SDR scenes or overly cool tones in HDR. However, it is worth noting the brightness characteristic. In SDR content, there are hardly any objections – the image looks very good, especially in older films, TV shows, or YouTube materials. Evaluating the television's performance in HDR is much more difficult. Analysis of the EOTF curve suggests correct behaviour, but its practical variant shows certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times it can dim the entire scene. Calibration has therefore brought clear benefits in terms of colour, but certain limitations resulting from local dimming and the way it is controlled by the C69KS cannot be avoided, which we also observed in the C6K test.

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.

The C69KS handles upscaling quite well. The tested 576p content looks surprisingly decent – a considerable amount of detail is preserved, and the algorithm adds a subtle ‘rounding’ effect to sharp edges, making the image appear more cohesive. However, it doesn't perform as well when it comes to smoothing tonal transitions. The television practically cannot improve them, leaving the image in a rather raw state. With older materials, this can be simply exhausting, as the lack of additional processing highlights all imperfections.

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.

C69KS offers a simplified motion enhancement panel in movies, allowing users to adjust the intensity of the effect using a slider. This makes it easy to tailor the smoothness to personal preferences. It also deserves credit for the ability to utilise higher refresh rates – even though the panel operates natively in 4K at 60 Hz, by lowering the resolution to 1440p, modes of 120 and 144 Hz can be enabled, on both consoles and PC. This sounds like great news, however, in practice, the image at these settings trails exceptionally badly. The effect is so pronounced that the overall experience simply appears mediocre and loses its appeal in everyday use.

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.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS is impressive in how well it performs for gaming. You get everything you would expect from a gaming TV: Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), Dolby Vision Gaming mode, and a consistently functioning HGiG. The TV can also operate at 120 or even 144 Hz at lower resolutions, making gameplay on console or PC smoother. Additionally, there's a clear Game Bar that allows you to quickly check key settings while gaming. As a result — despite a few limitations — the C69KS can be a genuinely successful screen for gamers.
