TCL C9K vs Samsung The Frame Pro

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.

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 decent result for a lifestyle model. In full-screen scenes, such as the frame from the movie The Meg or the opening sequence in Life of Pi, the brightness maintained a level of 700–800 nits. These values allow you to fully enjoy the HDR effects and capture their cinematic magic. However, the situation complicates when smaller, point light sources appear on the screen. The edge lighting used here, equipped with the ability to local dim whole strips, does not handle them very well. It happens that small elements are overly darkened, which weakens the effect, or conversely – they become heavily brightened, but at the cost of losing black depth in that part of the image. This can be compared to light halos reminiscent of a laser beam spreading in dense fog – an effect that is visible and bright but at the same time not very natural and distracting. Fortunately, the colour aspect performs better. Thanks to the use of a quantum dot filter (QLED), the colours are saturated, and the reproduction of the DCI-P3 palette reaches over 92%. Generally, movies or series watched in HDR on The Frame Pro present a rich colour palette, even if contrast and the performance of the lighting algorithms can sometimes draw our attention away.

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.

The best results were, of course, achieved in Filmmaker mode, which immediately showed that Samsung had put effort into the factory settings. In SDR content – the most commonly viewed materials – The Frame Pro performed really well. The white balance and gamma were almost perfectly set, making the image look natural and cohesive. Yes, there were some noticeable errors, particularly in skin tones and reds, which could be overly saturated, giving everything a slightly "warmed up" character, but in everyday use, it didn't hinder the viewing experience too much. For HDR content, the situation was similar regarding the white balance. It was at a good level, however, the biggest issue turned out to be managing brightness. The EOTF curve was set in such a way that in many scenes the image appeared blown out, and the brightest areas lost detail and resulted in uniform patches of light. This severely affected realism and made colours appear very oversharpened. Fortunately, Samsung provides the option for manual adjustment of the curve in their TVs, 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 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.

After calibration, the SDR mode looks almost perfect. We managed to eliminate the overly intense red saturation that previously gave the image a somewhat excessively warm character. The colours became more balanced, which translated into a natural and pleasant viewing experience for everyday content – from television to movies and series from streaming services or materials on YouTube. In HDR mode, the EOTF curve required the most work, as the factory settings caused excessive clipping of the entire image. The calibration significantly helped to "tame" this issue – the image stopped being overexposed, and details in the bright areas became more visible. Of course, the limits are set by the design of the television itself, as edge lighting reveals its limitations, and even the smallest elements of light can still appear overly bright or blend into the background. However, this is a matter of technology, not just calibration. After the correction, The Frame Pro is much more enjoyable to watch, and it is definitely worth considering if you want to make the most of the television's capabilities.

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.

Although in 4K HDR materials the fluidity of tonal transitions in the ChooseTV Pro is not a problem at all, naturally with weaker signal quality – such as with television, HD materials, or older Full HD films – imperfections may occur. Therefore, it's crucial how the television handles these limitations thanks to the image processor. The noise reduction feature works really effectively here. At the medium setting, it eliminates unwanted bands or artifacts, smoothing the image in a visible yet not overdone way. However, it's important to remember that Samsung has a tendency to be aggressive – even at the lowest level of this feature, it can "eat" film grain. So, it's wise to use it with caution and adjust the settings according to the material being watched.

The upscaling itself is of a high standard. The ChooseTV Pro effectively boosts older materials to a native 4K resolution, maintaining good sharpness and clarity. Movies and series in lower quality simply look better here. However, it's worth mentioning a minor downside – typical for many Samsung televisions. With very old sources in poor quality, you may notice some cropping 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 good to know that it may occur.

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.

The fluidity of movement in The Frame Pro is not only due to the panel itself, which operates at a refresh rate of up to 144 Hz, but also the image processor and motion smoothing system. It is thanks to this that we can adjust the way movies or sports broadcasts are displayed to our own preferences. Available are sliders for blur reduction and motion judder reduction – the first function enhances the sharpness of fast movements, while the second helps to soften the effect of the "jumping" image during camera pans. Everyone can choose between a cinematic character of motion and a smoother, more "television" style.

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.

Samsung The Frame Pro doesn’t pretend to be just a “living room” TV; gamers will also find something for themselves here. The manufacturer has ensured a full package of gaming features: we have support for variable refresh rate (VRR), auto low latency mode (ALLM), refresh rates up to 144 Hz, and compatibility with both G-Sync and FreeSync Premium Pro. Additionally, there’s the well-known Game Bar panel, which is a quick menu where you can check key parameters on-the-fly – from refresh rates to active image processing modes. Are there downsides? Yes, The Frame Pro doesn’t support Dolby Vision in game mode, but it’s hard to consider this a serious issue – most gamers use HDR10 anyway... so the HGIG mode. Exactly. The biggest surprise was the latest software update. Samsung... completely removed this option from The Frame PRO. In practice, this means that the TV independently interprets HDR tone mapping in games, and the user cannot enable settings designed with consoles in mind. This is a step backwards, which may disappoint more aware gamers hoping for full compliance with HGiG guidelines. We can only hope that this mistake will be quickly fixed.

An interesting feature of The Frame Pro is also the unusual placement of HDMI 2.1 ports. We have as many as five at our disposal – four are located in the One Connect module, and the fifth, in micro HDMI form, is located directly on the TV. This solution is quite unusual but very practical. Samsung clearly suggests that this is the port to connect your console or computer. Why? Because it minimises any potential delays associated with communication through the wireless One Connect, and in gaming, every millisecond counts. We have written separately about input lag, but we can reveal here that by connecting the equipment directly to the TV, we get the absolute maximum response speed from it.
