TCL C75B vs Samsung The Frame 2025 (LS03F)

During our brightness test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the TV performs decently in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the coverage of the DCI-P3 colour gamut at 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 solid on paper. But as we know – lab tests are one thing, and real film scenes are quite another story. When watching HDR materials in natural conditions, The Frame 2025 maintains very good results. In most film scenes, peak brightness stayed at around 550–650 nits. This is enough to feel the difference between standard picture and that in HDR quality – bright highlights, reflections on water, or moonlight look distinct and impressive.

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

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

An additional problem was the way brightness was reproduced. 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 black (e.g., the bottom part of the screen in the comparison image - the area around the actress's ear). The situation was similar on the EOTF curve, which was below the correct value, suggesting that a similar issue may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and check how much could be extracted from this model after professional calibration. The details are described in the next section.

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

After calibration, TCL C75B has clearly improved when it comes to colour reproduction. Although the TV doesn't offer too many options for adjusting the white balance, we managed to improve its settings quite a bit. As a result, the image is no longer overly pink, and the colours now look much more natural and harmonious.

The gamma jump that was previously an issue hasn't completely disappeared, but we were able to significantly reduce it. This has made details in dark scenes more visible – both in HD and 4K HDR content.

Unfortunately, the lack of local dimming is still noticeable. The 'blooming black' effect remains, but that's a limitation of the display itself. Still, the colours post-calibration look significantly better, and the image is much more pleasant to watch.

After calibration, the movie mode gained a completely new quality. The issue of the pink tint, which was previously clearly visible, especially in bright scenes, has been effectively eliminated. Colours started to look significantly more natural, and the white balance no longer dominated the rest of the image. It was no longer the same oversaturated "picture from a box" – everything took on coherence and a cinematic character. Additionally, the tendency of the TV to slightly brighten scenes, previously visible in the EOTF curve analysis, has been partially corrected. Of course, within the limits of what the design allows without local dimming – it's difficult to speak of perfect brightness management here. Nevertheless, the final effect was definitely closer to what one might expect from a mode named Filmmaker.

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

Image scaling is better. The TV handles it quite decently, although on thinner elements, like branches in the background, you can see slight jaggedness. However, this is not something that significantly hinders everyday viewing.

Unfortunately, a bigger problem turned out to be overscan, or cropping of the image edges. In our tests, it happened that news ticker or other elements close to the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the TV for watching news programs or content with text on the screen.

LS03F is equipped with an NQ4 processor, which is responsible for improving image quality – especially in lower-quality materials. In practice, it works surprisingly well, particularly when it comes to older content and recordings with lower resolution. Activating the "noise reduction" feature delivers noticeable results. The television 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 improvement – earlier, this feature often smoothed everything too much, including details that it shouldn't have removed. In this year’s model, the smoothing still occurs, but it happens in a much more acceptable way. Textures of materials, skin, or fabric details are not as heavily muted as before – the image retains more naturalness. However, this does not change the fact that film grain is still removed by the television, which may not appeal to everyone. On the other hand, it's no longer such an aggressive intervention as in previous models. It's also worth mentioning that the LS03F may struggle with very weak signals – for example, from VHS tapes or low-resolution video. In such cases, we noticed slight clipping of the image at the edges – the so-called overscan. This can lead to situations where a small part of the image (e.g., subtitles at the bottom edge) gets cut off.

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 budget range.

On top of that, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-point scale, providing significant personalisation possibilities – everyone can set the smoothness to their liking.

The new feature in The Frame for 2025 is a 144 Hz refresh rate display. Yes – in a television primarily associated with displaying works of art, you can now not only watch Van Gogh, but also comfortably play on a console or follow fast-paced sporting events. This is a significant step towards greater versatility. In the case of Samsung movies, as usual in models with a 120 Hz display and above, it allows you to adjust motion fluidity according to your preferences. You can set a more cinematic reproduction that maintains frame rate or opt for complete image smoothing. The range of options is broad, allowing you to tailor the effect to your tastes – regardless of whether the screening is meant to look like classic cinema or a performance on a modern theatre panel.

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

TCL C75B is undoubtedly a television designed with gamers in mind. It has almost everything needed for even the most demanding console users. With the implementation of full bandwidth HDMI 2.1, the TV supports features like ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating within the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detailing in HDR-optimised games. C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where you can check all key parameters such as refresh rate, input lag, or picture settings – all just a click away.

In one sentence: C75B is a great choice for gamers, offering a wide range of features that fully enable enjoyment of the capabilities of modern consoles and games.

As we mentioned earlier – although The Frame likely displays images and artwork for most of the time, Samsung recognised that a Van Gogh fan could just as easily be an avid gamer. And it must be said that The Frame 2025 has almost everything to become a fully-fledged gaming TV.

Onboard, we find support for ALLM (Auto Low Latency Mode) and Variable Refresh Rate (VRR) thanks to the implementation of a single HDMI 2.1 port. The TV handles lower resolutions at higher refresh rates effortlessly and features an expanded Game Bar – already known from other Samsung models – which allows for quick preview and adjustment of key gaming-related settings. For this, it gets extra points from us. Noteworthy is also the proprietary motion smoother, Auto Motion Plus Game, which – and this is worth emphasising – works without increasing input lag. Samsung remains the only manufacturer that has managed to implement this feature in a practically unnoticeable way regarding delays. The result? Much better fluidity in games, especially those that struggle to maintain a stable 60 frames. This solution can genuinely improve gaming comfort in more demanding titles – particularly on consoles that don’t always manage full fluidity, especially in AAA games.

As for the downsides – the lack of Dolby Vision is already something we consider standard in Samsung TVs, so there’s not much to specifically nitpick here. However, the problem lies elsewhere. In the latest version of the Tizen system, the HGiG option has disappeared. Literally – it’s gone. This is a significant inconvenience when configuring the console for proper HDR content display in games. It's hard to understand why such a decision was made, but one thing is certain – this needs to be fixed as soon as possible. We’re talking about a brand that has set standards for gaming on TVs for years. If HGiG returns – and we hope it does – The Frame LS03F can confidently aspire to be a proper gaming TV. Not only as a decoration on the wall, but as equipment that truly enhances the gaming experience.
