TCL C6K vs SONY BRAVIA 3

TCL C6K is a moderately bright television that can showcase its full potential under the best cinematic 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 is important to remember that when managing backlight zones, there are occasions where some elements are dimmed, and at times become barely visible. It is clear that there is a lack of proper algorithm optimisation here, although looking at the technical parameters in this price range, the overall construction performs exceedingly well.

Bravia 3 does not hide the fact that it belongs to the group of televisions that are rather modest in terms of brightness. Our measurements showed around 370 nits, which is a value teetering on the edge of where one can still speak of any HDR effect. For some, this is an acceptable level, while for others it is rather typical for SDR content, where spectacular highlights or vivid contrasts are not expected. The impression is that this is not a television for those focused on the highest image quality in demanding cinematic content. However, this does not mean that we cannot find any advantages here. Compared to its predecessor, the X75WL, Bravia 3 has gained an additional PFS filter, which works similarly to solutions known from QLED technology. Thanks to this, the DCI-P3 colour palette has been significantly widened and reaches over 91 percent, which in practice results in more saturated colours and a more pleasing image texture. As a result, even everyday content looks somewhat livelier, and films and series can surprise with vibrant visuals, despite limitations in brightness itself.

In this year's TCL televisions, the Filmmaker mode has appeared, and it must be admitted that it is definitely the best choice straight out of the box. This is the mode we recommend for daily watching of films 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 pronounced in the white balance. Conversely, with HDR content, we had the opposite impression – the image became cooler than it should have been due to an excess of blue. Additionally, the brightness characteristics sometimes led to overexposure. In practice, this resulted in quite noticeable errors in colour tests, which are difficult to accept in a mode advertised as "from the creators."

Sony Bravia 3 was primarily tested in film mode, which immediately proved to be the best choice among the factory settings. It is not a perfect picture, but compared to the eco mode that the television offers right out of the box, the difference is clear and positive. In film mode, one can notice a certain problem: the image appears too warm, which results from a lack of blue colour in the white balance. Despite this, in SDR content, the final effect can still be considered quite decent and satisfactory for everyday viewing. Much more serious errors occur in HDR materials. The Color Checker analysis showed considerable deviations, and poor brightness management, combined with limited colour gamut coverage, further exposes the shortcomings of the image in this mode. All of this makes HDR on the Bravia 3 appear unconvincing and can spoil the impression left by the quite decent SDR content setting. Fortunately, this is not an insurmountable situation. Various errors can be somewhat mitigated, and some can even be fully corrected through professional calibration. Therefore, we decided to check how the television would perform after such adjustments.

Thanks to the white balance adjustment, it was possible to significantly reduce the C6K's tendency to distort colours, which translated into a very good final result. After calibration, we will no longer observe the effect of excessive warmth in SDR scenes or overly cooling the image in HDR. However, it is worth taking a closer look at the brightness characteristics. In SDR content, it is difficult to have major objections – the image looks really good, especially in older films, television programmes, or materials from YouTube. It fares much worse in the case of HDR content. An analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the design become apparent. The television tends to over-brighten the smallest parts of the frame, and in other situations, it can dim an entire scene too much. The effect of calibration is therefore evident, and in terms of colour, the C6K has gained quite a lot, but certain limitations arising from local dimming and, in fact, from its management by the C6K simply cannot be overcome.

The calibration allowed us to extract significantly more from the Bravia 3 than we could have expected at the beginning. Firstly, it managed to compensate for the deficiency of blue, which had previously caused a noticeable warming of the image. After a slight adjustment to the white balance, most of the errors in the Color Checker measurements for SDR content virtually disappeared. The white tones became more natural, and the brightness management in gamma stabilised to an almost ideal level, not exceeding the threshold of human perception. Thus, it can be confidently stated that in SDR content, after a few adjustments to the settings, the Bravia 3 performs remarkably well. Significantly worse, although still definitely better than before calibration, are HDR contents. The white balance was brought into order, however, the limitations of the IPS panel are insurmountable. The lack of local dimming means that even the smallest elements can be overexposed, which immediately stands out. Colour-wise, the effect is also improved, though far from perfect – many errors still exceed the threshold of four or even five delta E units, meaning they remain visible to the human eye. It was already clear earlier that the Bravia 3 is not a television designed to impress with HDR quality. Nevertheless, it is gratifying that in SDR content, after calibration, the image can look truly excellent, and in this category, the television pleasantly surprised us.

TCL C6K performs quite well in terms of scaling. Lower quality materials look acceptable, and the absence of overscan issues means that the image is displayed in full, without cropping. However, one cannot expect miracles – very low-quality content will not gain a new life here, as the image processor has its limitations. On thin lines or details, there is a noticeable characteristic jerking, which reveals the lack of advanced image enhancement algorithms. It is also a pity that the C6K lacks the feature for smoothing tonal transitions – in older films or video materials, colour banding can be noticeable and can be distracting during longer viewing sessions.

Bravia 3 brings something more to the Sony TV 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 even so, it must be admitted that the image in lower resolutions looked surprisingly good. The scaling worked effectively, and most parts of the screen were free from the typical excessive edge tearing found in budget constructions.

Attention should also be paid to the function that improves the smoothness of tonal transitions. In the high setting, it works really well, effectively masking gradation imperfections without significant detail loss. It does happen, however, that the algorithm overly smooths elements that should remain sharp – for example, faces – but overall, the effect is beneficial. The best results were achieved precisely at the highest setting, and this option could be recommended to those watching lower quality content.

The TCL C6K utilises a 144 Hz panel, which is a significant advantage in this price range. This is an important step forward compared to the previous model, the C655 PRO, which only offered 60 Hz in 4K. The difference is especially noticeable when watching sports or gaming – the ball, players, or fast action in a game are shown more clearly and without losing details. Interestingly, the panel can also operate at 240 Hz, which the manufacturer does not mention in the official materials. We will return to this topic when discussing the PC gaming mode.

TCL has also added a feature for those watching films: "Motion Clarity", which allows users to adjust the image to their liking using two simple sliders. One can either keep the film frame visible or opt for a very smooth, almost theatrical effect. This way, everyone can find settings tailored to their taste.

The fluidity of motion has never been a strong point of televisions equipped with 60 Hz panels, and the Bravia 3 is no exception. Nevertheless, Sony has added something that may appeal to those more sensitive to the way images are displayed. We are talking about the proprietary motion smoother, Motion Flow, which offers users a considerable range of adjustment options. Thanks to it, one can make the image smoother, even theatrical, or stick to a more cinematic style with the characteristic judder that many simply associate with the 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 are the materials we encounter on a daily basis. It is here that the motion smoother proves to be one of the most important features in everyday use of the television, and this is where the Bravia 3 performs quite well.

The TCL C6K is a television that can confidently be described as equipment designed with gamers in mind. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there is a practical Game Bar, which is a panel with the most important settings easily accessible – useful when we want to quickly change something during gameplay (e.g. screen aspect ratio: Yes, it can be done!). The wide range of VRR is also noteworthy, reaching up to 240 Hz. However, this option is primarily for PC gamers who will drop the resolution below native 4K. At that point, the television can spread its wings and demonstrate extra fluidity, especially in fast-paced esports titles. In the case of consoles, we stick to the classic limit of 120 Hz, but the possibilities are still really broad. The only drawback might be slight ghosting, which can sometimes be seen in dynamic scenes. Apart from that, though, the C6K offers everything that gamers expect from a television.

Bravia 3 is not equipment for e-sports enthusiasts or fans of night marathons with a controller in hand. The lack of 120 Hz refresh rate and HDMI 2.1 ports closes the topic before it even has a chance to develop. This is a television for casual gamers who will play FIFA or racing games after work, not for someone who measures every frame in a spreadsheet. Nevertheless, Sony has added a few nice extras to ensure it’s not too sparse. ALLM works as it should, automatically switching the television to game mode (low latency). There’s even a simple Game Bar, which is clear. However, the biggest novelty here is the PlayStation Portal app. Thanks to it, you can launch PS5 games wirelessly and view them immediately on the television screen. It sounds great, but just a few minutes is enough to feel significant lag. In our opinion, it’s more of a showcase of capabilities than something that can be used every day. If someone really wants to play, it’s better to connect the console via HDMI cable and forget about wireless issues.
