TCL C6K vs SONY BRAVIA 3

TCL C6K is a moderately bright television that can showcase its full capabilities in the best movie conditions – the maximum brightness is around 600 nits. In scenes with large, intense light sources, the HDR effect can be truly satisfying, providing a sense of cinematic sparkle. However, it's important to remember that with local dimming management, there are situations where some elements become dimmed, and sometimes even barely visible. It is clear that there is a lack of proper optimization of the algorithms, although looking at the technical parameters in this price range, the build quality performs very well.

Bravia 3 does not hide the fact that it belongs to a group of TVs that are rather modest in terms of brightness. Our measurements showed around 370 nits, which is a value balancing on the brink where any HDR effect can still be discussed. For some, this is an acceptable level, while for others it is more typical for SDR materials, where spectacular flashes or vivid contrasts are not expected. The impression is that this is not a TV for those focused on the highest image quality in demanding film content. However, this does not mean that there are no advantages to be found here. Compared to its predecessor, the X75WL, the Bravia 3 has gained an additional PFS filter, which works similarly to solutions known from QLED technology. Thanks to this, the DCI-P3 color gamut has been significantly expanded, reaching over 91 percent, which in practice results in more saturated colours and a more pleasing texture of the image. As a result, even everyday content looks a bit more vibrant, and films and series can surprise with their colourful presentation, despite limitations in brightness itself.

This year's TCL televisions have introduced the Filmmaker mode, and it must be said that it is definitely the best choice right out of the box. This is the mode we recommend for everyday viewing of movies and series. Unfortunately, as is often the case, the best does not mean perfect. In the case of SDR content, the image was too warm, as the red was quite prominent in the white balance. On the other hand, with HDR content, we had the opposite impression – the image became cooler than it should have been, due to an excess of blue. There is also the brightness characteristic, which at times led to overexposure. In practice, these issues combined resulted in quite noticeable errors in colour tests, which are hard to accept in a mode advertised as “by the creators”.

We primarily tested the Sony Bravia 3 in movie mode, which immediately turned out to be the best choice among the factory settings. It's not a perfect picture, but compared to the eco mode that the TV suggests straight out of the box, the difference is evident and definitely better. In movie mode, there is a noticeable issue: the picture seems too warm, which is due to the lack of blue colour in the white balance. Nevertheless, in SDR content, the final effect can still be considered quite decent and satisfactory for everyday viewing. Much more serious errors arise in HDR materials. The Color Checker analysis showed significant deviations, and poor brightness management, combined with limited colour gamut coverage, further exposes the shortcomings of the picture in this mode. All of this makes HDR on the Bravia 3 look unconvincing and can ruin the impression left by the otherwise quite decent SDR content settings. Fortunately, it’s not a hopeless situation. Various errors can be somewhat mitigated, and some can even be completely corrected through professional calibration. That's why we decided to check how the TV would perform after such adjustments.

Thanks to the white balance adjustment, we were able to significantly reduce the C6K's tendency to distort colours, which resulted in a very good end result. After calibration, we won't observe the effect of excessive warming of scenes in SDR or overly cooling the image in HDR. However, it is worth taking a closer look at the brightness characteristics. In SDR content, it's hard to have major objections – the picture looks really good, especially in older movies, TV shows, or material from YouTube. It performs significantly worse with HDR content. An analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in movies), the limitations of the construction become apparent. The television tends to excessively brighten the smallest fragments of the frame, and in other situations, it can overly dim the entire scene. The effect of calibration is therefore noticeable, and regarding colourimetry, the C6K has really gained a lot, but certain limitations resulting from local dimming and actually from its management by the C6K simply cannot be overlooked.

Calibration allowed us to extract significantly more from ChooseTV 3 than we could have expected at the beginning. First and foremost, it managed to address the deficiency of blue, which previously caused a noticeable warming of the image. After a slight adjustment in white balance, most errors in the Color Checker measurements for SDR content practically disappeared. The whites took on a natural tone, and brightness management in gamma stabilised to an almost ideal level, not exceeding the threshold of what the human eye can perceive. So it is safe to say that in SDR content, after a few adjustments in the settings, ChooseTV 3 performs really well. It fares much worse, although still definitely better than before calibration, when it comes to HDR content. The white balance has been brought in line, but the limitations of the IPS panel are insurmountable. The lack of local dimming means that even the smallest elements can be overexposed, which is immediately noticeable. Colour-wise, the effect has also improved, although it is far from perfect – many errors still exceed the threshold of four, and even five delta E units, remaining visible to the human eye. It was already clear earlier that ChooseTV 3 is not a television designed to impress with HDR quality. Nevertheless, it is pleasing that in SDR content, after calibration, the picture can look really great and in this category, the television pleasantly surprised us.

TCL C6K performs quite well in terms of upscaling. Lower quality materials appear acceptable, and the absence of overscan issues means the image is displayed in full, without cropping. However, one cannot expect miracles – very low quality content won't come to life here, as the image processor has its limitations. On thin lines or details, there is characteristic tearing visible, which indicates a lack of advanced image enhancement algorithms. It is also a shame that the C6K lacks the function of smoothing tonal transitions – in older films or video materials, colour banding can be noticeable and may be distracting during longer viewing sessions.

Bravia 3 brings something more to the Sony television family than just a shared name. It stands out primarily for its ability to enhance the quality of weaker materials thanks to the processor used. Of course, we won’t find the advanced XR chip known from more expensive models here, but nonetheless, it must be said that the image in lower resolution looked surprisingly good. The scaling worked effectively, and most areas of the screen were free from the typical excessive edge roughness found in budget constructions.

Also worthy of attention is the function that improves the smoothness of tonal transitions. In high setting, it works really well, effectively masking gradation imperfections without significant loss of detail. It does happen that the algorithm overzealously smooths elements that should remain sharp – for example, faces – however, in the overall assessment, the effect is beneficial. The best results were achieved precisely at the highest setting, and this is the option we could recommend to those watching lower-quality content.

TCL C6K uses a 144 Hz panel, which is a significant advantage in this price range. It's an important step forward in comparison to the previous model C655 PRO, which only offered 60 Hz in 4K. The difference is especially noticeable when watching sports or playing games – the ball, players, or fast action in the game are displayed more clearly and without losing detail. An interesting fact is the panel's ability to operate at 240 Hz, which the manufacturer doesn't mention in official materials. We will return to this topic when discussing the PC gaming mode.

TCL has also added a feature for movie watchers: "Motion Clarity," which allows users to adjust the image according to their preferences with two simple sliders. You can either keep the visible film frame or opt for a very smooth, almost theatrical effect. This way, everyone can find settings that match their taste.

Motion smoothness has never been a strong point of televisions equipped with 60 Hz panels, and the Bravia 3 is no exception. Nevertheless, Sony has included something that may appeal to those more sensitive to the way images are displayed. I'm talking about the proprietary motion smoother, Motion Flow, which gives the user plenty of adjustment options. With it, one can make the image smoother, almost theatrical, or stick to a more cinematic style with characteristic judder that many people simply associate with a filmic atmosphere. These functions work with content at lower frame rates, such as films and series recorded at 24 or 30 frames per second, which is the material we deal with on a daily basis. This is precisely where the motion smoother proves to be one of the most important features in everyday TV usage, and here, the Bravia 3 performs really decently.

The TCL C6K is a television that can confidently be called equipment designed for gamers. We have 4K at 144 Hz, VRR support, an automatic gaming mode (ALLM), and Dolby Vision Gaming. On top of that, there's a practical Game Bar, which is a panel with the most important settings handy – useful when we want to quickly change something during gameplay (e.g. screen ratio: Yes, you can!). Notably, it has a wide range of VRR, reaching up to 240 Hz. However, this option is mainly for PC gamers who drop below the native 4K resolution. In that case, the television can spread its wings and show additional smoothness, especially in fast e-sport titles. For consoles, we stick with the classic limit of 120 Hz, but the possibilities are still quite broad. The only slight drawback is some minor motion blur that can occasionally be seen in dynamic scenes. Other than that, the C6K offers everything gamers expect from a television.

Bravia 3 is not gear for e-sports enthusiasts or fans of late-night marathons with a controller in hand. The lack of 120 Hz refresh rate and HDMI 2.1 ports shuts down the conversation before it even gets started. This is a TV for casual gamers who, after work, will fire up FIFA or racing games, not for someone who measures every frame in a spreadsheet. Nonetheless, Sony has thrown in a few nice additions so it’s not completely sparse. ALLM works as it should, automatically switching the TV to game mode (low latency). We even find a simple Game Bar here, which is clear and intuitive. However, the biggest curiosity here is the PlayStation Portal app. Thanks to this, you can launch PS5 games wirelessly and see them right on the TV screen. It sounds great, but it only takes a few minutes to feel significant lag. In our opinion, it's more of a showcase of capabilities than something that can be used day-to-day. If someone really wants to game, it's better to plug the console in with an HDMI cable and forget about wireless issues.
