TCL C9K vs Samsung The Frame Pro

As we mentioned with black 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 is capable of squeezing out… 4000 nits of brightness! It sounds astronomical, but – and here, unfortunately, the pattern repeats – the numbers say one thing, and practice says another. In real movie scenes, the situation looks different. At best, when the light effects occupy a large part of the image and the local dimming algorithm does not have to think too hard about what to do with thousands of zones – the effect is really good. At that point, the C9K can reach around 1500 nits, which provides a pleasant, intense flash and can indeed make a positive impression.

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

Samsung The Frame Pro belongs to relatively bright televisions. In synthetic tests, we managed to achieve values around 900 nits, which, for a lifestyle model, is quite a decent result. In full-screen scenes, such as the frame from the movie The Meg or the opening sequence in Life of Pi, brightness remained at levels of 700–800 nits. These are values that allow you to fully enjoy 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 locally dim entire strips, does not handle them very well. It sometimes happens that small elements are excessively dimmed, which weakens the effect, or on the contrary – they are significantly brightened, but at the cost of losing black depth in that part of the image. This can be compared to light glows resembling the spread of a laser beam in dense fog – the effect is visible and bright, but at the same time, it is not very natural and distracts our attention. Fortunately, the color aspect performs better. Thanks to the use of a quantum dot filter (QLED), the colors are saturated, and the reproduction of the DCI-P3 palette exceeds 92%. In general, movies or series watched in HDR on The Frame Pro present a rich color palette, even if the contrast and the operation of the backlight algorithms can sometimes distract our attention.

For color tests, as always, we reached for the Filmmaker mode – a new feature in TCL TVs for 2025. And while 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. On the other hand, in HDR, it went in the opposite direction: the image became excessively blue. The Colour Checker test revealed quite a few color errors 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 blow out the entire scene, giving it an unnatural, even grotesque character. It's hard to call this a "director-created" mode – because the director has certainly never seen such an image.

The best results were, of course, achieved in Filmmaker mode, which immediately showed that Samsung paid attention to the factory settings. In SDR content – the type of content most often viewed – The Frame Pro performed really well. White balance and gamma were almost perfectly matched, making the image look natural and consistent. Yes, there were some noticeable errors, especially in skin tones and reds, which could be overly saturated, giving everything a slightly “warmed up” character, but in everyday use, this did not significantly affect the viewing experience. In the case of HDR content, the situation was similar regarding white balance. It was at a good level; however, the biggest problem turned out to be brightness management. The EOTF curve was set in such a way that in many scenes the image appeared to be overexposed, and the brightest areas lost details and turned into solid patches of light. This severely undermined realism and made the colors appear strongly over-sharpened. Fortunately, Samsung provides the option for manual adjustment of the curve in its 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. Colors finally started to look the way they should, and the overall presentation was incomparably better than in the factory settings. In other words – it’s worth taking a moment to improve this, as the gain is truly significant. The gamma responsible for managing brightness was also brought into order in SDR content, and the effect was more than satisfying. 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 dimmed the darkest parts too much. Exactly as we saw in the scene from the movie Billy Lynn. So, the color improvement after calibration makes a great impression, but brightness management in HDR remains the Achilles' heel of C9K and presents a certain technological limitation.

After calibration, the SDR mode looks simply perfect. We managed to eliminate the overly strong red saturation that previously gave the picture a somewhat excessively warm character. The colors became more balanced, which translated to a natural and pleasant reception of daily content – from television to movies and series from streaming or materials on YouTube. In HDR mode, the EOTF curve required the most work, as it originally caused excessive burning of the entire image. Calibration largely helped to "tame" this problem – the image stopped being overexposed, and details in bright areas became more visible. Of course, the limits are set by the television's own design, as edge lighting reveals its limitations, and even the smallest elements of light can still be oversaturated or blend into the background. However, this is a matter of technology, not calibration itself. After the correction, The Frame Pro is much more enjoyable to watch, and it's definitely worth opting for if you want to make the most of your television's capabilities.

Digital image processing in TCL C9K is quite mediocre. The tonal smoothing feature seems to be present, but turning it on practically changes nothing – color bands are still visible, and it can unintentionally highlight elements we would prefer to hide, such as textures of objects. Fortunately, it doesn’t remove film grain, but that’s small comfort since the effects are still poor. Therefore, it's hard to recommend using this option.

On the other hand, image scaling performs much better. Lower quality materials look quite decent – characters and backgrounds are presented clearly, although, of course, with sources at 576p, physics cannot be fooled. Sometimes, characteristic aliasing on objects appears, but that’s the fault of the source itself, not the algorithm. A plus for not having issues with overscan – the image is not artificially cropped or enlarged.

While the smoothness of tonal transitions in 4K HDR content on The Frame Pro is not a problem at all, naturally with weaker signal quality – from television, HD content, or older Full HD films – imperfections may occur. Therefore, it is crucial how the television handles these limitations thanks to its 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 noticeable but not overly exaggerated way. However, it should be noted that Samsung tends to operate aggressively – even at the lowest setting of this feature, it can "eat" film grain. It is therefore advisable to use it with caution and adjust the settings to the material being viewed.

The upscaling itself is at a high level. The Frame Pro can effectively upscale older materials to native 4K resolution while maintaining good sharpness and readability. Movies and series in lower quality simply look better here. However, it is worth mentioning a minor drawback – typical for many Samsung televisions. With very old sources of poor quality, you may notice cropping of the image edges on the left side of the screen. This is not a problem that will ruin the viewing experience, but it is good to know that it may occur.

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

The smoothness of motion in The Frame Pro is ensured not only by the panel, which operates with a refresh rate of up to 144 Hz, but also by the image processor and the smoothing system. It is thanks to this that we can adjust the way we display movies or sports broadcasts to our own preferences. Available are sliders for motion blur reduction and judder reduction – the first function improves the sharpness of fast movements, while the second allows for softening the "jumping" image effect during camera pans. Therefore, everyone can choose between a cinematic character of motion and a smoother, more "television-like" 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 key technologies work: VRR (variable refresh rate) and ALLM (automatic low latency mode). Additionally, the manufacturer added a really intuitive Game Bar, which allows you to quickly preview the most important parameters and adjust settings without digging through the menu. Also, TCL's policy is a plus – the TV is not 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 wide freedom.

Samsung The Frame Pro doesn’t pretend to be just a “living room” television; here, gamers will also find something for themselves. The manufacturer has ensured a full suite 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’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 any downsides? Yes, The Frame Pro doesn’t support Dolby Vision in gaming mode, but it's hard to consider this a serious issue – most gamers use HDR10 anyway... so, the 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 TV independently interprets HDR tone mapping in games, and the user has no ability to enable settings designed for consoles. This is a step backward that may disappoint more informed gamers expecting full compliance with HGiG guidelines. We just hope that this mistake will be quickly corrected.

Interestingly, The Frame Pro also features an atypical arrangement of HDMI 2.1 ports. We have as many as five available – four are located in the One Connect module, and the fifth, in micro HDMI version, is directly on the TV. This solution is quite unconventional, but very practical. Samsung clearly suggests that this is the port to connect your console or computer. Why? Because it minimizes potential delays associated with communication through the wireless One Connect, and in gaming, every millisecond matters. We wrote separately about input lag, but it can be revealed here that by connecting equipment directly to the TV, we achieve the absolute maximum response speed.
