Samsung The Frame LS03D vs TCL C6K

Samsung The Frame LS03D really does well with brightness. Results at the level of 700 nits make bright elements on the screen look impressive and detailed, whether they illuminate the entire screen or appear as tiny points of light on a dark background. In more demanding scenes, like the fourth sequence from the film Sicario 2, the blacks perform moderately, but we have already discussed this in the section on contrast. However, when it comes to brightness – this television definitely holds its own. An additional advantage is the quantum dot coating, which is QLED technology. Thanks to this, the coverage of the colour palette has been improved, although The Frame does not stand out in this regard compared to the competition.

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.

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

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

In 4K HDR content, the white balance was once again dominated by red, this time combined with green. Meanwhile, blue clearly lost intensity, which could easily be seen on the Color Checker palette, where the colours began to "escape" in the wrong direction. The EOTF curve, responsible for brightness in HDR content, showed that the television tended to overly brighten the image, particularly in the darkest elements of scenes.

Overall, while it did not look terrible, it definitely required correction. Fortunately, Samsung offers extensive calibration options, which provides a chance for a significant improvement in picture quality. Therefore, we proceeded with professional calibration to unlock the full potential of this television.

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”.

After professional calibration, the Filmmaker Mode showcases its full potential. The white balance in HD content is exemplary – errors at the level of 0.5 indicate almost perfect accuracy in colour reproduction. The image now appears natural, and the colours are exactly as they should be. In 4K HDR content, the effect is not quite as perfect, but it still maintains a really high standard. The colours are vibrant, well-saturated, and the overall image quality is impressive.

So where does the problem lie, given our praise for the colour reproduction? Unfortunately, the entire experience is disrupted by the brightness characteristics. The gamma in HD content looks decent, but in 4K HDR, it’s not as good. The EOTF curve shows that the television excessively brightens certain parts of the image, which is a result of design limitations. The lack of local dimming means that the television is unable to accurately control the differences between the brightest and darkest areas of the screen. This is a barrier that simply cannot be overcome in this model.

Nonetheless, after calibration, Samsung The Frame LS03D offers excellent colour reproduction, particularly in HD content, and the overall look is significantly better than before the settings were adjusted.

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.

It's time to check how Samsung The Frame LS03D copes with older, lower-quality materials. We already know that the smoothness of tonal transitions is at a very high level, so we were curious to see how the TV would handle smoothing them out.

The noise reduction feature in the “Standard” setting does its job well – tonal transitions are noticeably smoothed out, and the image doesn’t lose too much detail. However, it’s worth noting that this effect also smooths out film grain, so its usage will be a matter of individual preference.

When it comes to image scaling, the TV performed really well too. The tested image came out solid – the model was accurately represented, with clear details. The branches in the background, although slightly frayed in places, generally look natural and do not stand out as a flaw.

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.

To start off, it’s worth noting that the model we tested in the 55-inch size, along with the 65, 75, and 85-inch versions, is equipped with a 120 Hz panel. Unfortunately, the 43 and 50-inch variants of this series only offer 60 Hz panels, which is worth considering when making a purchase. In terms of improving motion fluidity, the TV offers a feature called “Image Clarity.” This is a classic motion smoother that gives users the ability to adjust using two sliders:

Blur Reduction – this controls image sharpening during dynamic scenes. The higher the value, the less blurring occurs during fast camera moves or moving objects. However, setting it too aggressively can make the image look unnatural and resemble a “soap opera.”

Judder Reduction – this slider affects the smoothness of frame playback, especially in materials with lower frame rates, such as movies (24 fps). Higher settings can smooth out motion but can also lead to excessive “plasticity” of the image.

Both sliders operate on a scale from 0 to 10, allowing for precise adjustment of the effect to personal preferences. It’s a good idea to experiment with the settings to find the perfect balance between fluidity and a natural look for the image. We recommend setting them as shown in the picture.

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.

The Frame LS03D in the 2024 version is equipped with four HDMI ports, but only one supports the 2.1 standard with a bandwidth of 40 Gb/s. This is important 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 features for gamers, The Frame truly has a lot to boast about. We have ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate) and HGiG. It’s worth mentioning that HGiG has been very well implemented here, which is particularly important as the television does not support Dolby Vision in games (which is only available on Xbox consoles). In this case, HGiG turns out to be a better standard for gaming.

Samsung hasn't forgotten about features that enhance the gaming experience. Game Bar is an expanded panel for gamers that allows quick adjustment of screen settings without having to dig through the television menu. We can even change the aspect ratio from 16:9 to the panoramic 21:9, which can be a significant advantage for some gamers.

However, Samsung's biggest ace up its sleeve is the Game Motion Plus feature. This is a special smoother dedicated to games that adds additional frames of animation without significantly affecting input lag. The effect is really noticeable – the image seems much smoother, which will be particularly appreciated by fans of dynamic titles.

In summary – Samsung The Frame LS03D 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 television a truly enjoyable experience.

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.
