Samsung The Frame LS03D vs TCL C8K

Samsung The Frame LS03D really does well with brightness. Results at the level of 700 nits make bright elements on the screen look impressive and detailed, whether they illuminate the entire screen or appear as tiny points of light on a dark background. In more demanding scenes, like the fourth sequence from the film Sicario 2, the blacks perform moderately, but we have already discussed this in the section on contrast. However, when it comes to brightness – this television definitely holds its own. An additional advantage is the quantum dot coating, which is QLED technology. Thanks to this, the coverage of the colour palette has been improved, although The Frame does not stand out in this regard compared to the competition.

TCL C8K is a really bright television. In synthetic conditions – that is, during tests with brightness charts – it was able to achieve even 3500 nits peak brightness in movie mode. That's an impressive result and brings the C8K close to the market leaders, at least when it comes to panel brightness. More importantly – these aren't just numbers on paper. In films with a lot of bright scenes, such as Life of Pi or The Meg, the brightness clearly exceeds 1000 nits, providing a true sense of HDR effect. The picture in those moments looks very dynamic, colors are saturated thanks to excellent coverage of the color palette, and the lights are – spot on and intense. Exactly how it should be.

However, this doesn’t mean that everything is perfect. Just like in contrast tests, here too, in more demanding scenes, compromises appear. In sequences with very fine light elements – such as stars in the night sky or reflections in dark rooms – the local dimming algorithm can… get confused. Instead of bringing those details up, the television sometimes decides to dim them significantly – down to around 300 nits – to maintain deep blacks. On one hand, this is quite a sensible approach (better deep black than a grey/navy blue screen), but on the other – there may be moments when certain elements of the picture become difficult to see or even disappear into darkness.

TEST UPDATE (20/08/2025): The brightness control algorithm in this model is quite problematic – attempting to calibrate the picture so that it doesn’t drastically overexpose the brightest scenes results in unnatural shifts: improvement in one part of the image results in deterioration in another. The television may achieve slightly higher readings in brightness measurements, but in practice, this comes with a heavily overexposed image that looks very unnatural!

For the record, we provide brightness values without this adjustment:

1. 1463 nits

2. 640 nits

3. 1368 nits

4. 468 nits

5. 1025 nits

Samsung offers several picture modes in its televisions, but without a doubt, Filmmaker Mode is the one that should provide the most natural representation of content. Unfortunately, as often happens with mass production, the differences between individual units can be quite significant, and our tested model did not escape 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 photos – 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 robbed it of depth.

In 4K HDR content, the white balance was once again dominated by red, this time combined with green. Meanwhile, blue clearly lost intensity, which could easily be seen on the Color Checker palette, where the colours began to "escape" in the wrong direction. The EOTF curve, responsible for brightness in HDR content, showed that the television tended to overly brighten the image, particularly in the darkest elements of scenes.

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

In the C8K, a new picture mode has appeared: Filmmaker Mode. This is something we've known for years from televisions of other brands – a mode designed to deliver the director's vision as faithfully as possible, without unnecessary image enhancements. Unfortunately, at TCL, it seems to still be in the "to be refined" stage. Right from the first glance, the screen appears too warm – the image veers into reds, which may not appeal to everyone. The white balance was markedly skewed – the screen looked distinctly warm, and the red colour dominated almost every scene. There was a lack of blue, which led to an unpleasant yellowing and distortion of the image. But that’s not all. Regardless of whether we were watching regular TV, YouTube, or HDR films – the television had a clear tendency to excessively brighten the image. In tests of gamma curves and EOTF, the lines strayed instead of adhering to the standard, resulting in an overly bright and less contrasting image. Additionally, in colour reproduction tests, significant deviations were noticeable – on the colour wheel, some points were actually "drifting away." It must be said plainly: Filmmaker Mode in the C8K, in its current form, is not very cinematic.

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

So where does the problem lie, given our praise for the colour reproduction? Unfortunately, the entire experience is disrupted by the 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 design limitations. The lack of local dimming means that the television is unable to 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 look is significantly better than before the settings were adjusted.

After professional calibration, the TCL C8K has made a huge leap forward. In SDR content, the white balance has been almost perfectly set – the screen has finally stopped being too warm and has taken on a neutral character. The gamma curve, which is responsible for how brightness is represented, now looks very good – the image is more coherent and realistic. In HDR content, we also improved the white balance – within the limits of what the television itself allows. Unfortunately, the C8K still interprets brightness management a bit "in its own way." When we look at the EOTF chart in films, it’s clear that the television brightens entire scenes more than it should. Before calibration, this effect was quite bothersome – now the situation is much better, although it still falls a bit short of perfection. This, however, is a limitation of the device itself, which – despite our efforts – does not allow us to fully tame its nature.

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

The noise reduction feature in the “Standard” setting does its job well – tonal transitions are noticeably smoothed out, and the image doesn’t lose too much detail. However, it’s worth noting that this effect also smooths out film grain, so its usage will be a matter of individual preference.

When it comes to image scaling, the TV performed really well too. The tested image came out solid – the model was accurately represented, with clear details. The branches in the background, although slightly frayed in places, generally look natural and do not stand out as a flaw.

How does the TCL C8K handle lower quality materials? One could say: fairly well, though without much enthusiasm. The television offers a tonal transition enhancement feature designed to smooth out unwanted gradients. In practice, there's a slight improvement visible, but it's not at a level that eliminates all imperfections. The feature subtly softens harsh transitions, but it doesn't work miracles. Film grain isn't completely suppressed, and subtle banding on grey backgrounds can still be noticeable. But maybe that's for the best? – at least the image doesn't lose its texture or depth, as is often the case with televisions that overdo digital processing. When it comes to upscaling, which is enhancing picture quality from lower resolutions, the C8K performs quite well. The image is sharp, and details – though sometimes a bit softened – remain discernible. However, it's not on par with the best picture processors from the competition. On the plus side, there's no issues with overscan, which is the artificial cropping of the image that can still surprise in some models from other brands.

To start off, it’s worth noting that the model we tested in the 55-inch size, along with 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 considering when making a purchase. In terms of improving motion fluidity, the TV offers a feature called “Image Clarity.” This is a classic motion smoother that gives users the ability to adjust using two sliders:

Blur Reduction – this controls image sharpening during dynamic scenes. The higher the value, the less blurring occurs during fast camera moves or moving objects. However, setting it too aggressively can make the image look unnatural and resemble a “soap opera.”

Judder Reduction – this slider affects the smoothness of frame playback, especially in materials with lower frame rates, such as movies (24 fps). Higher settings can smooth out motion but can 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 personal preferences. It’s a good idea to experiment with the settings to find the perfect balance between fluidity and a natural look for the image. We recommend setting them as shown in the picture.

If you're planning a weekend with the Champions League or a marathon of F1 racing – the TCL C8K won't let you down. The television is equipped with a 144 Hz panel, so it should inherently handle fast motion well. And indeed – it performs very well. The fluidity of motion is at a very good level here, and the "Motion Clarity" feature with two sliders (blur reduction and flicker reduction) allows you to easily adjust the effect to your own preferences. Want to slightly smooth things out – no worries. Prefer a cinematic look – no problem.

The Frame LS03D in the 2024 version is equipped with four HDMI ports, but only one 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. We have ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate) and HGiG. It’s worth mentioning 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 hasn't forgotten about features that enhance the gaming experience. Game Bar is an expanded panel for gamers that allows quick adjustment of screen settings without having to dig through the television menu. We can even change the aspect ratio from 16:9 to the panoramic 21:9, which can 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 smoother dedicated to games that adds additional frames of animation without significantly affecting input lag. The effect is really noticeable – the image seems much smoother, which will be particularly appreciated by fans of dynamic titles.

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

TCL C8K offers practically everything we could expect from a screen for gamers. It has variable refresh rate (VRR), automatic game mode (ALLM), Dolby Vision in games, and a well-functioning implementation of HGiG, which helps preserve the creators' intent in HDR titles. The TV also supports 120 Hz in lower resolutions without any problems, and it can even display a staggering 288 Hz in Full HD – a figure that will surely appeal to fans of dynamic shooters and sports games on PC.

On board, we also find the GameBar – a graphical interface that somewhat resembles an elongated Nintendo Switch console. Thanks to this, we gain quick access to information about the current game mode, frame count, HDR format, and other little details that really make life easier for the gamer. We obviously couldn’t resist and ran a couple of races in Forza Horizon on the C8K – and we must admit, it looked and worked really well.

However, there is a slight drawback – in such a fast and clearly gaming-oriented device, it's a bit unfortunate that the manufacturer opted for the implementation of only two HDMI 2.1 ports. For some users, who use several next-gen consoles and, for example, a soundbar with eARC, this could be a limitation that’s hard to overcome.
