Samsung The Frame LS03D vs TCL C6K

Samsung The Frame LS03D performs really well with brightness. Results of 700 nits make bright elements on the screen look striking and detailed, whether they illuminate the entire screen or appear as small points of light against a dark background. In more demanding scenes, like the fourth sequence from the film Sicario 2, the black levels are average, but we have already discussed this in the section on contrast. As for brightness – the television definitely excels here. An additional advantage is the quantum dot coating, which is QLED technology. Thanks to this, the colour 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 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.

Samsung offers several picture modes on its televisions, but undoubtedly 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 considerable, and our tested model was not free from 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 images – 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 detracted from its depth.

In 4K HDR content, the white balance was again dominated by red, this time in combination with green. Meanwhile, blue clearly lost intensity, which was easy to notice on the Color Checker palette, where colours began to "drift" in the wrong direction. The EOTF curve, responsible for brightness in HDR content, showed that the television has a tendency to excessively brighten the image, especially in the darkest elements of scenes.

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

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."

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

So where does the problem arise, given our praise for colour reproduction? Unfortunately, the entire experience is marred by 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 construction limitations. The lack of local dimming means that the television cannot 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 appearance is considerably better than before the settings were corrected.

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.

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

The noise reduction feature in the "Standard" setting does its job well – tonal transitions are noticeably smoothed out, and at the same time, the image does not lose too much detail. However, it is 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 television also performed really well. The test chart turned out solid – the model was reproduced correctly, with clear details. The branches in the background, though slightly frayed in places, generally appear natural and do not stand out as imperfections.

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.

Firstly, it is worth noting that the model we tested in the size of 55 inches, 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 only offer 60 Hz panels, which is worth keeping in mind when making a purchase. As for improving motion fluidity, the television offers a feature called “Picture Clarity”. This is a classic motion smoother that gives users the ability to adjust it using two sliders:

Motion blur reduction – this controls the sharpening of the image in dynamic scenes. The higher the value, the less blur during quick camera movements or moving objects. However, overly aggressive settings may cause the image to become unnatural, appearing like a “soap opera”.

Judder reduction – this slider influences the smoothness of frame playback, particularly in materials with a lower frame rate, such as films (24 fps). Higher settings can smooth motion but may 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 one’s own preferences. It is worth experimenting with the settings to find the perfect balance between fluidity and a natural appearance of the image. We recommend setting them as shown in the picture.

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 Frame LS03D in the 2024 version has been equipped with four HDMI ports, but only one of them 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. Here we find ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and HGiG. It is worth highlighting 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 has also not forgotten about features that enhance gaming comfort. Game Bar is an advanced panel for gamers that allows for quick adjustment of screen settings without the need to dig through the television's menu. We can even change the aspect ratio from 16:9 to a panoramic 21:9, which may 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 smoothness enhancer dedicated to games that adds additional frames of animation without significantly affecting input lag. The effect is truly noticeable – the image appears much smoother, which fans of dynamic titles will particularly appreciate.

In summary – Samsung The Frame LS03D is a television that offers a solid set of features for gamers. While the limitation to one HDMI 2.1 port may be a downside, the rest of the solutions makes gaming on this television a truly enjoyable experience.

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.
