Samsung The Frame LS03D vs TCL C6K

The Frame really handles brightness well. With results at the level of 700 nits, bright elements on the screen look impressive and detailed, whether they illuminate the entire screen or appear as small bright spots against a dark background. In more demanding scenes, like the fourth sequence from the movie Sicario 2, the blacks perform averagely, but we already discussed that in the section regarding contrast. However, when it comes to brightness – here the TV definitely performs well. An additional advantage is the quantum dot coating, i.e., QLED technology. Thanks to it, the color palette coverage has been improved, although The Frame does not stand out in this regard compared to the competition.

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.

Samsung offers several picture modes in its TVs, but without a doubt, the Filmmaker Mode is the one that should provide the most natural representation of content. Unfortunately, as is often the case with mass production, the differences between units can be significant, and our tested model did not escape a few problems.

In the case of SDR content, the white balance heavily leaned towards red, with a slight boost in blue. This effect was particularly visible in comparison photos – in the example of a photograph with a boy, whose face was almost unnaturally flushed. The gamma, or brightness characteristic, also did not perform perfectly – the image was slightly brightened, which took away its depth.

In 4K HDR content, the white balance was again dominated by red, this time combined with green. Meanwhile, blue clearly lost intensity, which could be easily noticed on the Color Checker palette, where the colors began to "run away" in the wrong direction. The EOTF curve, responsible for brightness in HDR content, showed that the TV tends to excessively brighten the image, especially in the darkest elements of scenes.

Overall, although it did not look tragic, it definitely needed correction. Fortunately, Samsung offers extensive calibration options, which provide an opportunity for significant image improvement. Therefore, we proceeded with professional calibration to extract the full potential of this TV.

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."

After professional calibration, the Filmmaker Mode shows its full potential. The white balance in HD content is exemplary – an error level of 0.5 indicates almost perfect color reproduction precision. The image now looks natural, and the colors are exactly as they should be. In 4K HDR content, the effect is not as perfect, but it still maintains a really high level. The colors are vibrant, well-saturated, and the overall image quality is impressive.

So where does the problem arise, if we praise the color reproduction so much? Unfortunately, the overall experience is disrupted by the brightness characteristic. The gamma in HD content looks decent, but in 4K HDR it's not as good. The EOTF curve shows that the TV excessively brightens certain parts of the image, which is a result of design limitations. The lack of local dimming means that the TV cannot precisely control the differences between the brightest and darkest areas of the screen. This is a barrier that simply cannot be overcome in this model.

Nevertheless, after calibration, The Frame offers excellent color reproduction, especially in HD content, and the overall appearance is much better than before the settings correction.

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.

It was time to check how The Frame handles older, lower-quality materials. We already know that the smoothness of tonal transitions is very high here, so we were curious to see how the TV would manage their smoothing.

The noise reduction feature in the "Standard" setting performs well – tonal transitions are noticeably smoothed out, and the image does not lose too much detail. However, it's worth noting that this effect also smooths out film grain, so its use will be a matter of individual preference.

When it comes to image scaling, the TV also performed really well. The tested frame was solid – the model was rendered correctly, with clear details. The branches in the background, although slightly jagged in places, generally look natural and do not stand out as a flaw.

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.

First of all, it is worth noting that the model we tested in 55 inches, just like the 65, 75, and 85-inch versions, is equipped with a 120 Hz panel. Unfortunately, the 43 and 50-inch variants of this series offer only 60 Hz panels, which is worth considering when making a purchase. As for improving motion fluidity, the TV offers a feature called "Picture Clarity." This is a classic motion smoother that gives users the ability to adjust it using two sliders:

Motion Blurring Reduction – this is responsible for sharpening the image during dynamic scenes. The higher the value, the less blur during rapid camera movement or moving objects. However, overly aggressive settings can make the image look unnatural and start to resemble a “soap opera”.

Judder Reduction – this slider affects the smoothness of frame playback, particularly in materials with a lower frame rate, such as films (24 fps). Higher settings can smooth out motion but can also lead to an excessive "plasticky" effect on the image.

Both sliders operate on a scale from 0 to 10, allowing for precise adjustment of the effect to one’s own preferences. It is worth experimenting with the settings to find the perfect balance between fluidity and the natural appearance of the image. We recommend setting them as shown in the picture.

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 Frame in version 2024 is equipped with four HDMI ports, but only one of them supports the 2.1 standard with a bandwidth of 40 Gb/s. This is an important piece of information if we plan to connect more than one device that requires a 4K@120 Hz signal – for example, two consoles or a console and a gaming PC. In terms of gaming features, The Frame truly has a lot to offer. We find ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and HGiG. It is worth emphasizing that HGiG has been very well implemented here, which is particularly important since the TV does not support Dolby Vision in games (which is only available on Xbox consoles). In this case, HGiG proves to be a better standard for gaming. Samsung has not forgotten about features that enhance the gaming experience. Game Bar is an advanced panel for gamers that allows for quick adjustment of screen settings without the need to sift through the TV menu. We can even change the aspect ratio from 16:9 to cinematic 21:9, which for some gamers can be a significant advantage. However, Samsung's biggest ace up its sleeve is the Game Motion Plus feature. This is a special smoother dedicated to games, which adds extra frames of animation without significantly impacting input lag. The effect is really noticeable – the image appears much smoother, which fans of dynamic titles will particularly appreciate. In summary – Samsung The Frame is a television that offers a solid set of features for gamers. Although the limitation to one HDMI 2.1 port may be a downside, the rest of the solutions make gaming on this TV a truly enjoyable experience.

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.
