Samsung The Frame 2025 (LS03F) vs TCL C9K

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.

As we mentioned regarding black levels and contrast – the C9K can make a huge impression in synthetic tests. Our measurements showed that on a screen 10% filled with white, the television can achieve... 4000 nits of brightness! It sounds out of this world, but – and here's where the pattern unfortunately repeats – the numbers say one thing, and the practical experience says another. In real movie scenes, the situation looks different. In the best-case scenario, when light effects occupy a large part of the image and the local dimming algorithm doesn't have to ponder too much about what to do with thousands of zones, the effect is really quite good. At that point, the C9K can hit around 1500 nits, which delivers a pleasant, intense burst and can indeed leave a positive impression.

The problem arises with smaller elements – such as stars in the sky, the moon, or individual reflections. That's when the proverbial cat comes out of the bag: the algorithms are not yet refined, and brightness drops to as low as 400–500 nits. That's a huge difference from the potential 4000 nits we saw in lab tests. Why does this happen? Most likely, the television is trying to protect the black levels in this way and minimize the halo effect around bright objects. Unfortunately, this comes at the expense of detail – some details simply vanish, and the scene loses its nature.

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.

For colour tests, we once again reached for the Filmmaker mode – a new feature in TCL televisions for 2025. While the direction is a step in the right way, the execution leaves a lot to be desired. The white balance in SDR content turned out to be too warm – there was an excess of red. On the other hand, in HDR, it swung in the opposite direction: the image became excessively blue. The Colour Checker test revealed quite a few colour inaccuracies that were noticeable to the naked eye. An even bigger problem turned out to be what we mentioned above – brightness management. Regardless of whether we were watching SDR or HDR content, the image tended to wash out the entire scene, giving it an unnatural, almost grotesque character. Therefore, it’s hard to call this a "director's mode" – because no director has ever seen such an image.

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.

After calibration, we finally managed to tame the white balance – and it immediately translated into a more natural image. Colours finally started to look as they should, and the overall presentation was incomparably better than on the factory settings. In other words – it’s worth taking a moment to improve this, as the gain is really significant. The gamma responsible for brightness management also managed to be brought into order in SDR content, and the effect was more than satisfactory. Unfortunately, when we turned on HDR materials, the situation quickly became complicated. No matter how we set the local dimming, the television had a tendency to do what it liked with the image – either it overexposed everything or darkened the darkest parts too much. Just like we saw in the scene from the movie Billy Lynn. Colour-wise, the improvement after calibration makes a great impression, but brightness management in HDR remains the Achilles' heel of the C9K and presents a certain technological limitation.

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.

Digital image processing on the TCL C9K is rather average. The smooth tone transition feature seems to be present, but activating it practically changes nothing – colour bands are still visible, and it can unintentionally highlight elements we’d rather keep hidden, such as object textures. Fortunately, it doesn’t remove film grain, but that’s poor consolation given that the effects are still meagre. It’s therefore hard to recommend using this option.

On the other hand, image scaling presents itself much better. Lower quality materials look quite decent – characters and backgrounds are rendered clearly, although of course, with sources like 576p, the laws of physics cannot be fooled. Occasionally, there’s characteristic edge distortion of objects, but that’s the fault of the source itself, not the algorithm. A plus for not having issues with overscan – the image isn't artificially cropped or enlarged.

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.

Similar to the C8K, the C9K is also a really fast TV – both figuratively and literally. It features a 4K panel with a refresh rate of 144 Hz, and at lower resolutions, the panel can even ramp up to 288 Hz. Such speed translates into practice – while watching sports or playing games, the image looks very smooth and clear. Additionally, in movies, we get an extra motion smoother called Motion Clarity, which allows you to adjust the smoothness to your own preferences – from cinematic "judder" to almost theatrical smoothness.

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.

From a gaming perspective, the TCL C9K is a complete tool. It features two (out of four) full bandwidth 48 Gbps HDMI 2.1 ports, so all the key technologies work: VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). Additionally, the manufacturer has included a really intuitive Game Bar that allows you to quickly check the most important parameters and adjust settings without fumbling through menus. Also, TCL's policy is a plus – the TV isn’t afraid of any HDR formats, even in game mode. Whether it's HGiG or Dolby Vision for the Xbox Series S/X console – everything works as it should, giving the player plenty of freedom.
