SAMSUNG S95F (TANDEM OLED 83") vs TCL C9K

Samsung S95F in the 83-inch variant with Tandem OLED panel also enchants with HDR effects. In test movie scenes, such as "Life of Pi" or "Sicario 2," where smaller light points dominate – stars in the night sky, the glow of the moon, or headlights – the television easily achieves brightness values exceeding 2000 nits. This is a result that not long ago seemed unattainable for OLEDs and places this model in the same category as the best Mini-LED designs.

The limitations of organic panels reveal themselves only in full-screen scenes completely filled with white. In the case of this model, for example, in the last shot from the movie The Meg, brightness drops to around 1000 nits – a bit lower than in the smaller QD-OLED variants, where the result remained around 1400 nits. Nevertheless, we are still talking about a remarkable result, unprecedented in OLED televisions of this size. Color reproduction is equally impressive. The new Tandem OLED panel essentially catches up with QD-OLED televisions, offering excellent coverage of a wide color gamut. The results are slightly weaker than those of QD-OLED, but in practice, they still provide an image whose intensity and naturalness of colors are hard to compare with any other television.

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.

The best picture mode straight out of the box is undoubtedly Filmmaker Mode. This mode has been present in Samsung TVs for several years, and its intention is to reproduce the image as faithfully as possible to the creators' vision. In SDR content, it works reasonably well, although not without flaws. The picture is slightly dimmed, and the white balance tends to shift towards red and blue, resulting in a slight pinkish hue on the screen. Average color errors hover around ΔE values of 3–4, which is on the edge of what most people can perceive with the naked eye.

The limitations are much more apparent with HDR content. Here, a slight excess of blue in the white balance is not as big of a problem – the real issue becomes how the TV manages brightness. In many scenes, the picture looked as if it had been overexposed, and details in the dark could completely disappear. The final effect did not represent what the equipment of this class is capable of and led to significant color errors. It’s hard to understand why such a factory characteristic was chosen, as the HDR reception in this version definitely was not what it should be.

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.

After calibration, the S95F shows what it is truly capable of. The white balance was corrected, and minor inaccuracies were adjusted, making the image in SDR content look almost exemplary. Color differences have dropped below the level that the human eye can detect – looking at the screen, one simply feels a full sense of naturalness and color coherence.

In HDR, the improvement is equally noticeable. The television handles brightness much better, eliminating the "blowing out" effect of the entire frame. Bright scenes are more controlled, and blacks retain more detail, although sometimes there may still be slight brightening of the image as a whole. Nevertheless, after calibration, the S95F delivers an image that can confidently be called one of the best on the market – regardless of whether we are watching films in SDR or spectacular productions in HDR.

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.

The Samsung S95F model features a noise reduction function aimed at improving the fluidity of tonal transitions. Its performance is hard to call ineffective – on the contrary, it can excessively interfere with the image. Older films or materials of lower quality, such as those from YouTube, take on a soft, smoothed character because of it, reminiscent of a painted effect. The problem is that along with the noise, the natural film grain, which gives the image a cinematic quality, also disappears. Fortunately, the function does not blur essential details, so its use is more a matter of taste. If someone prefers a slightly polished and smooth image, it’s worth turning it on, but in our opinion, the most sensible setting is “Standard”.

Upscaling leaves a better impression. The S95F efficiently enhances the quality of lower resolution content – even 576p video looks quite good, although some minor artifacts in the form of blockiness can be noticed. Overall, the effect is very solid, although when compared to the competition – such as the Sony Bravia 8 (II) or LG G5 – it can be seen that those models can extract a bit more from the image. However, it's worth remembering one inconvenience: with older films and photos, there is an overscan issue that causes a slight cropping of the left edge of the image.

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.

In the case of the 83-inch S95F with a Tandem OLED panel, the motion smoothness also makes a huge impression. The panel in native 4K resolution offers a refresh rate of 165 Hz, and this combined with organic technology makes games and sports look remarkable. Additionally, the manufacturer added a film smoother and a motion blur reduction system, allowing each viewer to adjust the image to their own preferences – whether it's a more "frame-rate" cinematic effect or a smooth, almost theatrical spectacle.

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 low trailing and phenomenal motion fluidity, which are the hallmarks of OLED technology, are just the warm-up. The Samsung S95F has been designed with gamers in mind – and this is evident at every turn. Four HDMI 2.1 ports with a bandwidth of 40 Gb/s may sound like a compromise on paper, but in practice, neither consoles nor PCs will experience the slightest limitations. On board is a complete set of gaming features: variable refresh rate (VRR), automatic low latency mode (ALLM), and a flawlessly implemented HGiG standard, which allows you to enjoy HDR exactly as the creators intended. All of this is complemented by Game Bar – an intuitive control center where you can check and adjust the most important settings in seconds.

Particular attention should also be paid to Game Motion Plus, Samsung's own smoothing technology. It can add extra fluidity to animations, which can be a lifesaver in games running at 60 frames, where stability doesn't always hold up. Indeed, support for Dolby Vision in games is missing, but it's hard to consider this a serious flaw – the manufacturer compensates for this gap with other solutions. The S95F is one of the absolute favorites for the title of the best gaming TV on today's market.

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.
