TCL C6K vs SONY BRAVIA 3

TCL C6K is a moderately bright TV 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 really satisfying, providing a sense of cinematic brilliance. However, it should be noted that when managing the backlighting zones, there are situations where some elements become dimmed and sometimes can even become barely visible. It is clear that there is a lack of proper algorithm optimization here, although looking at the technical parameters in this price range, the design itself performs very 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 balancing on the borderline where one can still speak of any HDR effect. For some, this is an acceptable level; for others, it is rather typical for SDR materials, 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 film content. However, this does not mean that we won't find any advantages here. Compared to its predecessor, the X75WL, Bravia 3 has gained an additional PFS filter, functioning similarly to solutions known from QLED technology. Thanks to this, the DCI-P3 color gamut has been significantly expanded and reaches over 91 percent, which in practice provides more saturated colors and a more pleasant image texture. As a result, even everyday content looks a bit livelier, and movies and series can surprise with their colorful presentations, despite the limitations in brightness itself.

This year's TCL televisions feature a Filmmaker mode, and it must be admitted that it is definitely the best choice straight out of the box. This is the mode we recommend for everyday watching of movies and series. Unfortunately, as is often the case, the best doesn't mean perfect. In the case of SDR content, the image was too warm because the red was strongly emphasized 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 excess blue. Additionally, the brightness characteristic sometimes led to highlights being blown out. In practice, this resulted in quite noticeable color test inaccuracies that are hard to accept in a mode advertised as "by the creators."

We primarily tested the Sony Bravia 3 in movie mode, which immediately proved to be the best choice among the factory settings. The picture is not perfect, but compared to the eco mode that the TV suggests right out of the box, the difference is significant and for the better. In movie mode, one can notice a certain problem—the image seems too warm, which results from a lack of blue in the white balance. Despite this, in SDR content, the final effect can still be considered quite decent and satisfying for everyday viewing. Much more serious errors occur in HDR materials. The Color Checker analysis showed significant deviations, and poor brightness management combined with limited color gamut coverage further exposes the shortcomings of the image in this mode. All of this makes HDR on the Bravia 3 look unconvincing and can spoil the impression left by the quite decent SDR content settings. Fortunately, this is not a situation without a solution. Various errors can be somewhat mitigated, and some can even be completely corrected through professional calibration. Therefore, we decided to check how the TV would perform after such adjustments.

Thanks to the white balance correction, it was possible to significantly reduce the C6K's tendency to distort colors, which resulted in a very good final outcome. After calibration, we will no longer 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, there are few complaints – the image looks really good, especially in older movies, TV shows, or materials from YouTube. This is much worse for HDR content. Analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the construction become apparent. The TV tends to overly brighten the smallest parts of the frame, and in other situations, it can dim the entire scene too much. The effect of calibration is therefore evident, and in terms of color, the C6K has gained quite a lot, but certain limitations arising from local dimming and, in fact, its management by the C6K simply cannot be overcome.

The calibration allowed us to extract significantly more from ChooseTV 3 than we could have expected at the beginning. First and foremost, we managed to address the shortage of blue color, which previously caused a noticeable warming of the image. After a slight adjustment in white balance, most of the errors in Color Checker measurements for SDR content practically disappeared. The shades of white gained a natural quality, and brightness management in gamma stabilized to a level that is nearly perfect, not exceeding the threshold of human eye perception. Therefore, it can be confidently said that in SDR content, after a few tweaks in settings, ChooseTV 3 performs really excellently. HDR content, however, fares much worse, although it is still definitely better than before calibration. The white balance has been corrected, but 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. Color-wise, the effect has also improved, although it is far from ideal—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 before that ChooseTV 3 is not a television designed to amaze with HDR quality. Nonetheless, it is gratifying that in SDR content, after calibration, the image can look really great, and in this category, the television pleasantly surprised us.

The TCL C6K performs quite well in terms of scaling. Lower quality materials look acceptable, and the lack of overscan issues means that the image is displayed in full, without cropping. However, one cannot expect miracles – content of very low quality will not gain new life here, as the image processor has its limitations. On thin lines or details, the characteristic tearing is visible, which reveals the absence 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, color banding can be noticeable and may be bothersome during long viewing sessions.

Bravia 3 brings something more to the Sony television family than just a common name. It stands out primarily for its ability to improve the quality of weaker materials thanks to the applied processor. Of course, we won't find the advanced XR chip known from more expensive models here, but it must be acknowledged that the image at a lower resolution looked surprisingly good. Scaling worked effectively, and most parts of the screen were free from the typical excessive jagged edges found in budget constructions.

The feature that enhances the fluidity of tonal transitions is also worth noting. In the high setting, it works really well, effectively masking the imperfections of gradation without significant loss of detail. It does happen that the algorithm overly smooths elements that should remain sharp – for example, faces – however, in overall terms, 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.

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

TCL also added a feature for movie watchers: "Motion Clarity," which allows you to adjust the image to your preferences using two simple sliders. You can keep the movie 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 TVs equipped with 60 Hz panels, and the Bravia 3 is no exception. Nevertheless, Sony has added something that might appeal to those who are more sensitive to the way images are displayed. We are talking about the proprietary Motion Flow motion smoother, which offers users a lot of adjustment options. Thanks to it, one can make the image smoother, even theatrical, or stick to a more cinematic style with the characteristic stuttering that many simply associate with the film atmosphere. These features work with content at lower frame rates, such as movies and series recorded at 24 or 30 frames per second, which are the materials we encounter on a daily basis. It is precisely in this area that the motion smoother proves to be one of the most important features in everyday use of the television, and here the Bravia 3 performs really well.

The TCL C6K is a TV that can confidently be called equipment designed for gamers. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there's a practical Game Bar, a panel with the most important settings readily available – useful when we want to quickly change something during gameplay (e.g., screen aspect ratio: Yes, that’s possible!). The wide VRR range, reaching up to 240 Hz, deserves attention. However, this is mainly an option for PC gamers who drop below the native 4K resolution. Then the TV can spread its wings and show additional smoothness, especially in fast-paced e-sports titles. In the case of consoles, we stick to the classic limit of 120 Hz, but the possibilities are still quite broad. The only drawback is a slight ghosting that can sometimes be seen in dynamic scenes. Other than that, the C6K offers everything gamers expect from a TV.

Bravia 3 is not a device 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 wraps up the topic before it can even develop. This is a TV for casual gamers who, after work, want to fire up FIFA or racing games, not for someone who measures every frame in a spreadsheet. Nevertheless, Sony has added a few nice extras so it’s not too barren. ALLM works as it should, automatically switching the TV to game mode (low latency). We even find a simple Game Bar here that is clear. However, the biggest curiosity is the PlayStation Portal app. With it, you can launch games from PS5 wirelessly and immediately see them on the TV screen. It sounds great, but it only takes a few minutes to feel significant delays. In our opinion, it’s more of a showcase of capabilities than something usable on a daily basis. If someone really wants to play, it’s better to connect the console with an HDMI cable right away and forget about wireless problems.
