TCL C75B vs Samsung The Frame 2025 (LS03F)

During our test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. They can be considered average – the television does not perform poorly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, these results are better than those of budget models, which can achieve almost half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the positive side, it's worth mentioning the DCI-P3 colour gamut coverage of 95%. This is a very good result that easily suffices to enjoy a wide range of colours in content available on popular streaming platforms. Vivid and rich colours are definitely a strong point of this model.

The Frame LS03F is a television that can surprise with its brightness. The maximum luminance reaches around 650 nits, which already looks impressive on paper. But as we know, laboratory tests are one thing, and real film scenes are quite another. When watching HDR materials in natural conditions, The Frame 2025 maintains very good results. In most film scenes, the peak brightness remained at around 550–650 nits. This is a sufficient value to feel the difference between standard picture quality and that of HDR – bright highlights, reflections on water, or moonlight are presented clearly and spectacularly.

It is also worth remembering that the LS03F is a QLED television, which translates into solid colour saturation. The coverage of the DCI-P3 colour space reaches about 92%, allowing for vibrant, intense colours in HDR content. This is not the level of top premium models, but for a lifestyle screen, the result truly deserves recognition.

TCL C75B offers several picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the television struggles with some colour reproduction issues. In our tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered accurate. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit for this phenomenon turned out to be the white balance, characterised by an excessive amount of blue and red in both HD and 4K HDR materials.

An additional problem was the way brightness was rendered. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, disappearing into complete blackness (e.g., the lower part of the screen in the comparison photo - around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that we might encounter a similar problem in 4K HDR content.

Thanks to our experience and the right tools, we decided to take matters into our own hands and see how much we could extract from this model after professional calibration. We describe the details in the next section.

When it comes to image quality straight out of the box, even in Filmmaker mode, which is supposed to be the closest to reference, there were issues. We noticed clear deviations in white balance in both HD and 4K HDR content. The image was heavily skewed towards red and blue, giving the screen a characteristic pinkish tint. This effect was most noticeable in bright scenes – for example, in shots with a lot of white, where neutral light should naturally dominate. At such moments, the screen clearly took on pink tones, which is also visible in the attached comparison photo. As for the brightness characteristics – it wasn’t as bad as one might expect with such colour inaccuracies. The analysis of the gamma curve and EOTF showed a slight brightening of the image compared to the reference, but not enough to drastically ruin the viewing experience.

After calibrating the TCL C75B, it has clearly improved in terms of colour reproduction. Although the television does not offer many options for adjusting the white balance, we managed to enhance its settings quite significantly. As a result, the image is no longer excessively pink, and the colours now look much more natural and harmonious.

The gamma jump, which was previously an issue, has not completely disappeared, but we have managed to reduce it considerably. This has made details in dark scenes more visible – both in HD and 4K HDR materials.

Unfortunately, the lack of local dimming is still noticeable. The "blooming black" effect remains, but that is a limitation of the display itself. Nevertheless, the colours after calibration look far better, and the image is much more enjoyable to watch.

After calibration, the movie mode has gained a completely new quality. The issue of the pink tint, which had been clearly visible before, especially in bright scenes, has been effectively eliminated. Colours now look much more natural, and the white balance no longer dominates the rest of the image. It is no longer the same exaggerated "box picture" – everything now has coherence and a cinematic character. Additionally, the tendency of the television to slightly brighten scenes, previously visible in the EOTF curve analysis, has been partially corrected. Of course, this is within the limits of what the design allows without local dimming – one cannot speak of perfect brightness management here. Nevertheless, the final effect was definitely closer to what one might expect from a mode called Filmmaker.

TCL C75B has a tone transition smoothing function, but unfortunately, we cannot commend it. Regardless of the selected level – low or high – tone transitions in older materials remained visible, as if the function wasn't working at all. It's hard to say anything positive about it, as in practice it seems completely useless.

The image scaling is better. The television performs quite decently, although on thinner elements, like branches in the background, you can notice slight jaggedness. However, this is not something that significantly interferes with daily viewing.

Unfortunately, a bigger problem turned out to be overscan, which is cutting off the edges of the image. In our tests, there were instances where news tickers or other elements near the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the television for watching news programmes or content with text on the screen.

LS03F has been equipped with the NQ4 processor, which is responsible for improving image quality – particularly in lower quality materials. In practice, this works surprisingly well, especially when it comes to older content and recordings with lower resolution. Activating the "noise reduction" function yields noticeable effects. The TV effectively smooths tonal transitions and removes digital noise that can appear in darker areas of the image. Compared to previous generations, there is a clear advancement – previously, this function often smoothed everything too much, including details that it shouldn't remove. In this year's model, smoothing still occurs, but in a much more acceptable manner. Textures of materials, skin, and fabric details are no longer subdued as strongly as before – the image retains more naturalness. However, this does not change the fact that film grain is still removed by the TV, which may not appeal to everyone. On the other hand, it is no longer as aggressive an intervention as in previous models. It is also worth mentioning that the LS03F may struggle with very weak signals – for example, from VHS tape recordings or low-resolution video. In such cases, we noticed slight clipping of the image at the edges – so-called overscan. This can lead to a situation where a small part of the image (e.g., subtitles at the bottom edge) gets cut off.

The TCL C75B definitely has something to offer gamers. The television is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really impressive results, especially for a model from the entry-level range.

In addition, there are features for improving fluidity and reducing motion blur in films. The "Motion" option allows precise adjustment of the effect on a 10-point scale, which offers great personalisation possibilities - everyone can set the fluidity as they like.

The new feature in The Frame for 2025 is a display with a refresh rate of 144 Hz. Yes – in a television that is mainly associated with displaying works of art, you can now not only watch Van Gogh but also comfortably play on a console or follow dynamic sports events. This is a definite step towards greater versatility. In the case of Samsung films, as usual in models with a display rate of 120 Hz and above, it allows you to adjust motion smoothness according to your preferences. You can set a more cinematic reproduction while maintaining frame rate or opt for full motion smoothing. The range of options is broad, allowing you to tailor the effect to your own taste – whether the viewing experience is meant to resemble classic cinema or a show on a modern theatre screen.

*this part of the test refers to the LS03FAU model in sizes 55 and 65 inches, which is equipped with a 144Hz panel, while sizes 43 and 50 inches have 60Hz displays, and thus perform much worse in terms of motion smoothness.

The TCL C75B is undoubtedly a television designed with gamers in mind. It offers nearly everything that even the most demanding console users could need. With the implementation of fully capable HDMI 2.1, the television supports features like ALLM (Automatic Low Latency Mode) and VRR (Variable Refresh Rate) – operating within the full potential of the television, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, allowing for even better detail reproduction in HDR-optimised games. The C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where all key parameters such as refresh rate, input lag, and image settings can be checked – all within a single click.

In a nutshell: the C75B is a great choice for gamers, offering a wide range of features that allow users to fully enjoy the capabilities of modern consoles and games.

As we mentioned earlier – although The Frame is likely to display images and works of art most of the time, Samsung recognised that a Van Gogh enthusiast could just as easily be an avid gamer. And it must be admitted that The Frame 2025 has almost everything needed to become a full-fledged gaming television.

On board, we find support for ALLM (Automatic Low Latency Mode) and Variable Refresh Rate (VRR) thanks to the implementation of one HDMI 2.1 port. The television handles lower resolutions at higher refresh rates effortlessly and features an advanced Game Bar – already known from other Samsung models – which allows for a quick preview and change of the most important gaming-related settings. For this, it earns extra points from us. The proprietary motion smoother Auto Motion Plus Game is also worth mentioning, which – it is worth emphasising – operates without increasing input lag. Samsung remains the only manufacturer that has managed to implement this feature in a practically invisible manner in terms of delays. The effect? Much better fluidity in games, especially those that struggle to maintain a stable 60 frames per second. This solution can realistically improve the gaming experience in more demanding titles – particularly on consoles, which do not always manage full fluidity, especially in AAA games.

As for the downsides – the lack of Dolby Vision is already considered standard in Samsung televisions, so there is not much to particularly criticise here. However, there is a different issue entirely. In the latest version of the Tizen system, the HGiG option has disappeared. Literally – it is not there. This is a significant hindrance when configuring the console for proper HDR content display in games. It is hard to understand why such a decision was made, but one thing is certain – this should be fixed as soon as possible. We are talking about a brand that has set standards for gaming on televisions for years. If HGiG returns – and we hope it will – The Frame LS03F can confidently aspire to be called a genuine gaming television. Not just as a decoration on the wall, but as equipment that truly provides joy in gaming.
