Sony BRAVIA 5 (XR5) vs TCL C9K

Looking at similar results in terms of blackness and contrast, we expected equally stable performance as last year's model when it came to HDR content. Unfortunately – and this needs to be said outright – there has been a regression here that is hard to overlook. The paradox is that the peak brightness of the Bravia 5 is impressive: in our synthetic tests, the television achieved around 1000 nits in HDR. Sounds great, right? The problem is that this power does not always translate effectively to all film scenes. When small, point-like elements appear on the screen, something that had usually been polished with surgical precision in Sony's case is this time noticeably lacking. The algorithms attempt to maintain deep black around small objects, but the side effect is that details can be dimmed to such an extent that they become barely visible. Just consider the example of the film Sicario 2 – in some scenes there, small light sources practically disappeared, as if someone had covered them with dark film.

Of course, not everything looks so dramatic. In simpler, brighter scenes, where the image is filled with more light, the Bravia 5 shows that it can shine: literally and figuratively. Then the television achieves values in the range of 600–800 nits, which we saw both in synthetic tests and during film screenings. The impression is really positive; the brightness adds dynamism, and the colours appear vibrant and fresh. However, there remains a certain dissonance. We feel a slight confusion because evidently something has gone in a direction it shouldn’t have. Technological progress – more zones, greater backlighting power – has not been supported by the well-crafted image management that we usually associate with Sony. Fortunately, there are elements that have not been worsened and are, in fact, at a very high level. We are talking about colour reproduction. Thanks to the application of the PFS filter, the colour palette coverage is excellent – around 97% DCI-P3 and 75% BT.2020. These are values that allow for truly broad colour reproduction, giving films a sense of naturalness and cinematic quality.

As we mentioned with black and contrast – the C9K makes a huge impression in synthetic tests. Our measurements showed that on a screen 10% filled with white, the television is capable of squeezing out... 4000 nits of brightness! It sounds cosmic, but – and here unfortunately the pattern repeats – the numbers say one thing, and practice another. In real film scenes, the situation looks different. In the best case, when the light effects occupy a large part of the image and the local dimming algorithm doesn't have to think too hard about what to do with thousands of zones – the result is really quite good. At that point, the C9K can reach about 1500 nits, which provides a pleasant, intense flash and can indeed make a positive impression.

The problem begins with smaller elements – such as stars in the sky, the moon, or individual reflections. That's when the proverbial cat comes out of the bag: the algorithms are not yet refined, and brightness drops even to 400–500 nits. This is a huge difference compared to the potential of 4000 nits that we saw in laboratory tests. Why does this happen? Most likely, the television tries to protect the black and minimise the halo effect around bright objects. Unfortunately, this comes at the cost of details – some of the intricate details simply disappear, and the scene loses its nature.

Sony Bravia 5 was of course tested in the best possible mode, which is the Cinema mode. Right out of the box, it provides the most natural colours, definitely better than anything offered by the "eco" or "dynamic" modes, which are more suited for a showroom display than for a living room. However, the Cinema mode alone does not mean we can always expect cinematic picture quality. With SDR content, we had virtually no major complaints – the slightly warmed white balance gave the scenes a somewhat golden tone, but it was nothing that was visually jarring. However, the problem arose with HDR material. Here, the colour reproduction simply looked poor. The white balance was heavily skewed – with an excess of blue and a clear lack of red. At times, it resembled the store's "super vibrant image" mode, where everything is overexposed and artificially boosted.

This situation also made brightness management seem overly aggressive. The EOTF graph clearly showed that the television had problems with overexposing many scenes right out of the box. And while we know what Sony televisions are usually capable of, it was difficult to remain indifferent here – thus we quickly decided to go for calibration.

For colour tests, we once again reached for the Filmmaker mode – a new feature in TCL televisions for 2025. And although the direction itself is a step in the right direction, the execution leaves much to be desired. The white balance in SDR content turned out to be too warm – there was an excess of red. Conversely, in HDR, it swung in the opposite direction: the image became excessively blue. The Colour Checker test revealed quite a few colour inaccuracies that were noticeable to the naked eye. An even bigger problem turned out to be what we mentioned above – managing brightness. Regardless of whether we were watching SDR or HDR content, the image had a tendency to blow out the entire scene, giving it an unnatural, almost grotesque character. Therefore, it is hard to call this a 'director’s mode' – because the director surely has never seen such an image.

After calibration, the situation changed dramatically. We managed to adjust the white balance so that entire scenes began to look more natural, and the image gained cohesion and elegance. In HDR, we finally got rid of that unwanted clipping effect that had previously marred some shots. Suddenly, it turned out that the Bravia 5 can extract significantly more from films than the “out of the box” impression suggested. Indeed, if we look at the graphs and compare them with the patterns, we can see that the beginning of the EOTF curve slightly deviates from the reference line. However, this is not so much a calibration error as it is a natural limitation of Mini-LED technology, which cannot be bypassed. Sony, instead of clinging to perfect black, prefers to prioritise the visibility of details – and in practice, it's hard to disagree with that. We would rather see the texture of the material on the screen than a pitch-black blob where all nuances are lost.

The calibration itself was truly beneficial. After about an hour spent on the settings, we felt that the image resembled that from the best cinema halls – of course on a home scale, but with the same sense of quality and refinement. And in such moments, we remember why we like Sony televisions: because when we fine-tune them, they can reward us with an image that captivates for long hours.

After calibration, we finally managed to tame the white balance – and it immediately translated into a more natural image. Colours finally started to look as they should, and the overall presentation was incomparably better than with the factory settings. In other words – it’s worth taking a moment to improve this, as the gain is really significant. The gamma responsible for managing brightness was also brought under control in SDR content, and the effect was more than satisfactory. Unfortunately, when we switched on the HDR material, the situation quickly became complicated. No matter how we set the local dimming, the television had a tendency to do what it pleased with the image – either overexposing the whole picture or dimming the darkest parts too much. Just like we saw in the scene from the film Billy Lynn. Colour-wise, the improvement after calibration makes a great impression, but managing brightness in HDR remains the Achilles' heel of the C9K and constitutes a technological limitation.

Bravia 5 carries within it the genes of Sony, which have remained untouched – and thank goodness for that, because we are talking about absolutely remarkable digital image processing. It is no coincidence that for years it has been believed that it is televisions of this brand that set the standard for how a screen should handle lower quality materials. If someone still watches classic television, old films or YouTube in lower resolutions, here they get equipment that can transform such content into an unexpectedly pleasant experience. On board, we find several tools worth activating. The first of these is "digital noise reduction". Set to a medium level, it works perfectly – smoothing tonal transitions, which usually cause the most trouble in low-quality materials, while not introducing any artificial artifacts. Importantly, it also does not remove the filmic character, meaning the natural grain that is intentionally present in many productions. Another advantage of the Bravia 5 is the upscaling capabilities of the XR processor. The image displayed after scaling is soft, yet at the same time sharp and clear. The contours of characters are clearly visible, while backgrounds retain their structure without excessive artificial sharpening. It’s hard to find a better television for watching lower quality materials – Bravia 5 only confirms why Sony is regarded as a benchmark in this field.

The digital image processing in TCL C9K is rather mediocre. The tone transition smoothing feature is supposedly present, but activating it hardly makes any difference – colour banding is still visible, and it can inadvertently highlight elements we would prefer to hide, such as textures of objects. Fortunately, it does not remove film grain, but that's scant consolation considering the effects are still poor. Thus, it's hard to recommend using this option.

On the other hand, image scaling performs significantly better. Lower quality materials look quite decent – characters and backgrounds are represented clearly, although of course, with sources like 576p, the limitations of the physics cannot be disguised. Sometimes, there's characteristic aliasing of objects, but that's due to the source itself, not the algorithm. A plus for the fact that there are no overscan issues – the image is neither artificially cropped nor enlarged.

Bravia 5 received a 120 Hz panel, which in itself sounds like an invitation to watch sports, fast matches, or spectacular action films. However, the real magic begins when MotionFlow – Sony's proprietary smoothness technology – comes into play. Thanks to it, we can adjust the character of the image to our own preferences. The "smoothness" slider allows you to transition from a cinematic feel with a slight "jitter" of the film frame to a nearly theatrical fluidity, where every ball in the match glides across the screen as if on a string. The higher the value, the smoother and more fluid it is; the lower it is, the more cinematic and natural it feels. In the options, we will also find an additional setting that Sony has called "clarity". This is nothing more than the BFI function (i.e., inserting black frames), which is meant to improve motion sharpness. It sounds great in theory, but in practice, one must use it with great caution. Why? Because all higher settings cause brightness drops of up to half, and in some cases, contour doubling also appears. Therefore, if we wish to use it, we recommend the lowest possible level – "1" out of the available ten. This way, we gain a bit better motion clarity without risking a loss of half the image brightness.

Similar to the C8K, the C9K is also a really fast television – both figuratively and literally. On board, we have a 4K panel with a refresh rate of 144 Hz, and at lower resolutions, the panel can even ramp up to 288 Hz. Such speed translates into practice – while watching sports or playing games, the picture looks very smooth and clear. Additionally, in films, we get an extra motion smoothing feature called Motion Clarity, which allows you to adjust the smoothness to your own preferences – from the cinematic "stuttering" of frames to nearly theatrical smoothness.

In the Bravia 5, there is a significant improvement compared to the X90L model from two years ago. The television offers literally everything its predecessor had, but this time the issues that could frustrate gamers have been fixed. The problems with setting variable refresh rate (VRR) have disappeared, and there are no longer any issues with configuring HDR content in HGiG mode. In short: we get hardware that simply works as it should, without any fuss. Therefore, the Bravia 5 has everything you could expect from a modern gaming television – and it can be reasonably advertised with the slogan “ready for PS5.” This is a statement we couldn't make about the X90L model. Well done, Sony!

It’s just a shame that this relatively high-priced model lacks a full set of four HDMI 2.1 ports. In everyday use, this won’t be a problem for most people, but if someone has a console, soundbar, and additional equipment hooked up via HDMI, at some point there will be a need to choose or juggle the cables.

For gaming, the TCL C9K is a complete tool. Here we have two (out of four) HDMI 2.1 ports with full bandwidth of 48 Gbps, so all the key technologies work: VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). Additionally, the manufacturer has included a really intuitive Game Bar, which allows you to quickly check the most important parameters and adjust settings without rummaging through the menu. Also worth noting is TCL's policy – the television does not shy away from any HDR formats, even in game mode. Whether it's HGiG or Dolby Vision for the Xbox Series S/X console – everything works as it should, giving the player a wide range of freedom.
