TCL C9K vs Samsung The Frame Pro

As we mentioned with black and contrast – the C9K makes a huge impression in synthetic tests. Our measurements showed that on a screen 10% filled with white, the television is capable of squeezing out... 4000 nits of brightness! It sounds cosmic, but – and here unfortunately the pattern repeats – the numbers say one thing, and practice another. In real film scenes, the situation looks different. In the best case, when the light effects occupy a large part of the image and the local dimming algorithm doesn't have to think too hard about what to do with thousands of zones – the result is really quite good. At that point, the C9K can reach about 1500 nits, which provides a pleasant, intense flash and can indeed make a positive impression.

The problem begins 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 even to 400–500 nits. This is a huge difference compared to the potential of 4000 nits that we saw in laboratory tests. Why does this happen? Most likely, the television tries to protect the black and minimise the halo effect around bright objects. Unfortunately, this comes at the cost of details – some of the intricate details simply disappear, and the scene loses its nature.

Samsung The Frame Pro is one of the relatively bright televisions. In synthetic tests, we managed to achieve values around 900 nits, which is quite a respectable result for a lifestyle model. In full-screen scenes, such as the board from the film The Meg or the initial sequence in Life of Pi, brightness maintained a level of 700–800 nits. These values allow you to fully enjoy the HDR effects and convey their cinematic magic. However, the situation becomes complicated when smaller, point light sources appear on the screen. The edge lighting used here, equipped with the ability to locally dim entire strips, does not manage these well. Sometimes, small elements are overly dimmed, which weakens the effect, or conversely – they are significantly brightened, but at the cost of losing the depth of black in that part of the image. This can be compared to light beams reminiscent of a laser beam spreading in dense fog – the effect is noticeable and bright, yet at the same time, it is quite unnatural and distracting. Fortunately, the colour aspect performs better. Thanks to the use of a quantum dot filter (QLED), colours are saturated, and the reproduction of the DCI-P3 palette exceeds 92%. Generally, films or series watched in HDR on The Frame Pro showcase a rich colour palette, even if contrast and the functioning of the dimming algorithms can sometimes distract us.

For colour tests, we once again reached for the Filmmaker mode – a new feature in TCL televisions for 2025. And although the direction itself is a step in the right direction, the execution leaves much to be desired. The white balance in SDR content turned out to be too warm – there was an excess of red. Conversely, 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 – managing brightness. Regardless of whether we were watching SDR or HDR content, the image had a tendency to blow out the entire scene, giving it an unnatural, almost grotesque character. Therefore, it is hard to call this a 'director’s mode' – because the director surely has never seen such an image.

We achieved the best results, of course, in Filmmaker mode, which immediately showed that Samsung had put effort into the factory settings. In SDR content – the type most commonly viewed – The Frame Pro performed really well. The white balance and gamma were almost perfectly matched, giving the image a natural and cohesive appearance. Admittedly, there were some noticeable errors, particularly in skin tones and reds, which could be overly saturated, giving everything a slightly "warmed-up" character, but this didn’t significantly detract from the viewing experience in everyday use. For HDR content, the situation was similar regarding the white balance. This was at a good level; however, the biggest issue turned out to be brightness management. The EOTF curve was set in such a way that in many scenes, the image appeared blown out, with the brightest areas losing detail and turning into uniform patches of light. This severely undermined realism and caused the colours to appear overly sharpened. Fortunately, Samsung provides the option for manual adjustment of the curve in their televisions, so we opted for calibration, and its results can be seen below.

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 with 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 managing brightness was also brought under control in SDR content, and the effect was more than satisfactory. Unfortunately, when we switched on the HDR material, the situation quickly became complicated. No matter how we set the local dimming, the television had a tendency to do what it pleased with the image – either overexposing the whole picture or dimming the darkest parts too much. Just like we saw in the scene from the film Billy Lynn. Colour-wise, the improvement after calibration makes a great impression, but managing brightness in HDR remains the Achilles' heel of the C9K and constitutes a technological limitation.

After calibration, the SDR mode looks absolutely perfect. We managed to eliminate the overly strong red saturation, which previously gave the image a somewhat excessively warm character. Colours have become more balanced, which resulted in a natural and pleasant reception of everyday content – from television to films and series from streaming or materials on YouTube. In HDR mode, the most work was required on the EOTF curve, which factory settings caused excessive brightening of the entire image. Calibration allowed us to largely "tame" this problem – the image stopped being overexposed, and details in bright areas became more visible. Of course, the limitations are set by the design of the television itself, as edge lighting reveals its constraints, and the smallest elements of light can still be overblown or blend into the background. However, this is a matter of technology, not just calibration. After the correction, The Frame Pro is significantly more enjoyable to watch, and it is certainly worth considering if you want to maximise the television's capabilities.

The digital image processing in TCL C9K is rather mediocre. The tone transition smoothing feature is supposedly present, but activating it hardly makes any difference – colour banding is still visible, and it can inadvertently highlight elements we would prefer to hide, such as textures of objects. Fortunately, it does not remove film grain, but that's scant consolation considering the effects are still poor. Thus, it's hard to recommend using this option.

On the other hand, image scaling performs significantly better. Lower quality materials look quite decent – characters and backgrounds are represented clearly, although of course, with sources like 576p, the limitations of the physics cannot be disguised. Sometimes, there's characteristic aliasing of objects, but that's due to the source itself, not the algorithm. A plus for the fact that there are no overscan issues – the image is neither artificially cropped nor enlarged.

Although the fluidity of tonal transitions in 4K HDR materials on The Frame Pro is not a problem at all, naturally, with a weaker signal - television, HD materials, or older Full HD films - imperfections may arise. Therefore, it is crucial how the television copes with these limitations thanks to its image processor. The noise reduction function works really effectively here. At the medium setting, it eliminates unwanted bands or artefacts, smoothing the image in a noticeable yet not excessive way. However, it's worth noting that Samsung tends to be aggressive in its approach - even at the lowest level of this function, it can "consume" film grain. So it's advisable to use it judiciously and adjust the settings to the material being viewed.

The upscaling itself is at a high level. The Frame Pro can effectively enhance older materials to a native 4K resolution while maintaining good sharpness and readability. Films and series in lower quality simply look better here. However, it should be mentioned that there is a minor drawback - typical for many Samsung televisions. With very old sources of poor quality, you may notice clipping of the image edges on the left side of the screen. It's not a problem that will ruin the viewing experience, but it's worth knowing that it might occur.

Similar to the C8K, the C9K is also a really fast television – both figuratively and literally. On board, we have 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 picture looks very smooth and clear. Additionally, in films, we get an extra motion smoothing feature called Motion Clarity, which allows you to adjust the smoothness to your own preferences – from the cinematic "stuttering" of frames to nearly theatrical smoothness.

The smoothness of motion in The Frame Pro is not only due to the matrix, which operates with a refresh rate of up to 144 Hz, but also the image processor and the smoothing system. It is thanks to this that we can adjust the way films or sports broadcasts are displayed to our own preferences. There are sliders for reducing blurring and reducing judder – the first function improves the sharpness of fast movements, while the second helps to soften the effect of a "jumping" image during camera pans. So, everyone can choose between a cinematic motion character and a smoother, more "television" style.

For gaming, the TCL C9K is a complete tool. Here we have two (out of four) HDMI 2.1 ports with full bandwidth of 48 Gbps, 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, which allows you to quickly check the most important parameters and adjust settings without rummaging through the menu. Also worth noting is TCL's policy – the television does not shy away from 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 a wide range of freedom.

Samsung The Frame Pro does not pretend to be just a “living room” television; here, gamers will also find something for themselves. The manufacturer has ensured a full range of gaming features: we have support for variable refresh rate (VRR), automatic low latency mode (ALLM), refresh rates up to 144 Hz, and compatibility with both G-Sync and FreeSync Premium Pro. Additionally, there is the well-known Game Bar panel, which is a quick menu where key parameters can be checked on the fly—from refresh rates to enabled image processing modes. Are there any downsides? Indeed, The Frame Pro does not support Dolby Vision in game mode, but this is hard to consider a serious issue—most gamers use HDR10 anyway... which means HGIG mode. Exactly. The biggest surprise turned out to be the latest software update. Samsung… completely removed this option from The Frame PRO. In practice, this means that the television independently interprets HDR tone mapping in games, and the user has no way to enable settings developed for consoles. This is a step backwards that may disappoint more knowledgeable gamers hoping for full compliance with HGiG guidelines. We can only hope that this issue will be resolved quickly.

An interesting feature of The Frame Pro is also the unusual arrangement of HDMI 2.1 ports. There are as many as five available—four are located in the One Connect box, and the fifth, in micro HDMI version, is directly on the television. This is quite an unusual solution, but rather practical. Samsung clearly suggests that this is the port to which you should connect your console or computer. Why? Because it minimises potential delays associated with communication through the wireless One Connect, and in the case of gaming, every millisecond matters. We have written separately about input lag, but it can already be revealed here that by connecting equipment directly to the television, we achieve the absolute maximum in response speed.
