Samsung The Frame 2025 (LS03F) vs TCL C6KS / C69KS / Q6CS

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.

And what about HDR? Here, the C6KS performs quite well and – as has become a recurring theme of this review – identically to the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect, and generally, the video materials look good here. However, one must keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g., stars) appear against a dark background, the television can dim them quite significantly. The goal is simple: to eliminate blooming and maintain the best possible blacks. This is quite a reasonable compromise. Most viewers will definitely appreciate deep, "true black" more than additional micro-details, the display of which could cause the screen to appear greyed out. This is the nature of local dimming technology in this price range, and one must be aware of it. It is also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the slogan of QLED technology. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92% here.

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.

Unlike the more expensive C6K model, the tested C6KS does not have an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of colour reproduction, the lack of this specific label makes virtually no difference. The best available Film/Cinema mode here offers an almost identical picture characteristic to the aforementioned Filmmaker in the more expensive model. So we get a very similar image, just under a different name. Therefore, if you were wondering whether paying extra for the C6K gives you better colours – the answer is no, in both cases the base is the same and requires slight adjustments.

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.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, resulting in a very good final effect. After calibration, we will no longer see excessive warming of scenes in SDR or overly cool tones in HDR. However, it is worth noting the brightness characteristics. In SDR content, it is hard to have any objections – the image looks very good, especially in older films, television programmes, or materials from YouTube. It is significantly more challenging to evaluate the television's performance in HDR. Analysis of the EOTF curve suggests correct behaviour, but its practical variant reveals certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times, it can dim the entire scene. Thus, calibration brought clear benefits in terms of colour quality, but certain limitations resulting from the local dimming operation and the way it is controlled by the C69KS cannot be overlooked, as we also saw in the C6K test.

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 C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a considerable amount of detail is retained, and the algorithm adds a slight "rounding" effect to sharp edges, making the image appear more cohesive. The performance in smoothing tonal transitions is less impressive. The television practically cannot improve them, leaving the image in a rather raw state. With older material, this can be quite tiring, as the lack of additional processing highlights any imperfections.

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.

C69KS offers a simplified motion enhancement panel in films, allowing the adjustment of effect intensity with a slider. This makes it easy to match fluidity to personal preferences. The ability to use higher refresh rates is also a plus – although the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p enables 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, however, in practice, the image at these settings exhibits significant motion blur. The effect is so pronounced that the overall presentation appears merely average and loses its appeal for everyday use.

As we mentioned earlier – although The Frame likely displays images and artworks most of the time, Samsung has recognised that a Van Gogh enthusiast could just as easily be a passionate gamer. And it must be admitted that The Frame 2025 has almost everything to become a fully-fledged gaming television.

On board, we find support for ALLM (automatic game 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 without any issues and features an extensive Game Bar – already known from other Samsung models – which allows for quick preview and change of the most important gaming-related settings. For this, it earns extra points from us. It is also worth highlighting the custom motion smoothening technology, Auto Motion Plus Game, which – and it is worth emphasising – works without increasing input lag. Samsung remains the only manufacturer that has managed to implement this feature in a practically unnoticeable manner regarding delays. The result? Much better fluidity in games, especially those that struggle to maintain a stable 60 frames. This solution can genuinely improve the gaming experience in more demanding titles – particularly on consoles that do not always manage full fluidity, especially in AAA games.

As for the downsides – the lack of Dolby Vision is already regarded as standard in Samsung televisions, so there's nothing to specifically complain about here. However, the issue is something entirely different. In the latest version of the Tizen system, the HGiG option has disappeared. Literally – it is gone. This is a significant hindrance when configuring consoles 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 years when it comes to gaming on televisions. If HGiG returns – and we hope it will – The Frame LS03F can confidently aspire to the title of a genuine gaming television. Not just as a wall decoration, but as equipment that truly provides enjoyment in gaming.

[UPDATE] We have updated our tests of Samsung televisions from the 2025 model year due to the release of software version 1131, which restored the HGiG function crucial for gamers.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS impresses with how well it performs during gaming. We get everything one can expect from a gaming television: variable refresh rate (VRR), automatic switching to game mode (ALLM), Dolby Vision Gaming mode, and a well-functioning HGiG. The television can also operate at 120 and even 144 Hz at lower resolutions, allowing for smoother gameplay on a console or PC. Additionally, there is a clear Game Bar that lets you quickly glance at key settings while gaming. As a result — despite a few limitations — the C69KS can be a really successful screen for gamers.
