SAMSUNG OLED S95F (QD-OLED) vs TCL C69K / Q6C

The new generation of QD-OLED panels in the Samsung S95F shows its full potential, and the brightness results are absolutely stunning. In test film scenes, such as "Life of Pi" or "Sicario 2," where smaller light elements appear – stars, the moon, or headlights – the TV was able to achieve over 2000 nits of brightness. This is a result that surpasses even most top Mini-LED models.

The secret lies in the technology itself – instead of a limited number of dimming zones like in Mini-LED TVs, we have millions of glowing pixels here, allowing the TV to fully showcase its power without technological compromises. Of course, since it is still an organic panel, in full-screen scenes flooded with white – like in the final sequence of the film The Meg – the brightness drops to around 1400 nits. Nevertheless, the result remains excellent and definitely exceeds what any OLEDs, both QD-OLED and WOLED, have offered so far. The color reproduction also deserves special attention. Thanks to QD-OLED technology, the TV achieves almost 100% coverage of the DCI-P3 color palette and about 80% in BT.2020. These values make the HDR image not only dazzling with brightness but also captivating with a richness of colors.

In terms of brightness, TCL C69K / Q6C is a moderate model. Under optimal movie conditions, it shows its full potential, reaching a maximum of around 600 nits. In scenes with large, intense light sources, the HDR effect can be truly satisfying, providing a cinematic sparkle. However, it should be noted that when managing the backlight zones, there are situations where some elements of the image become dimmed, and sometimes they are barely visible. This suggests that there is still a lack of proper optimization of algorithms, though considering the technical parameters in this price range, the construction still looks very good.

The best picture mode right out of the box is undoubtedly Filmmaker Mode – a mode that Samsung has been using for several years, designed to faithfully represent the creators' intentions. In SDR content, its implementation is not bad, although some imperfections can be noticed. The picture is slightly dimmed, and the screen has a slight pinkish tint resulting from the predominance of red and blue in the white balance. Color errors remained at a level of 3–4 ΔE units – and for the uninitiated: a value above 3 is the threshold where the average human eye begins to notice differences.

However, much larger problems arise in HDR content. Here, the white balance was not such a significant issue – a slight excess of blue did not cause major problems. The issue became managing brightness. In practice, the TV "overexposed" the image too much, causing details in the blacks to completely disappear. The final effect was far from what was expected, and the color errors in this mode became really large. It's hard to say why such a design decision was made, but it was clear that the factory HDR settings did not allow this TV to showcase its full potential.

The Filmmaker mode, which has arrived in this year's TCL televisions (including the C69K / Q6C), is definitely the best choice "to start with." This is the mode we recommend for everyday viewing of movies and series. Unfortunately, as is often the case, best does not mean perfect. In SDR content, the image turned out to be too warm, with a strong red tint in the white balance. We had the opposite impression with HDR content – here the image became cooler than it should have, due to an excess of blue color. Additionally, the brightness characteristics sometimes resulted in overexposure. In practice, this translated to quite noticeable errors in color tests, which is hard to accept in a mode labeled as “by the creators.”

After calibrating, it was possible to make subtle adjustments in white balance and significantly improve the image characteristics. In SDR content, the quality has become practically reference-level—most color errors have fallen below a ΔE value of 1, which is the level at which the human eye can no longer detect differences. This is a result that places the S95F among the absolute top televisions available on the market.

In HDR materials, calibration also brought significant improvement. The tendency of the television to overexpose the image was successfully controlled, as confirmed by the analysis of the EOTF curve. A slight tendency to brighten the entire scene or occasional loss of details in the blacks can still be observed; however, it does not significantly impact the overall perception. After calibration, the S95F showcases its full potential and can be described as one of the best televisions on the market!

Through white balance adjustment, we were able to significantly reduce the tendency of C69K / Q6C to distort colors, which resulted in a very good final outcome. After calibration, the issue of excessive warmth in SDR scenes and overly cool images in HDR disappeared. However, it is worth closely analyzing brightness characteristics. While there are few complaints about SDR content - the image looks really good, especially in older movies, TV programs, or on YouTube - the situation is much worse with HDR content. Analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the design become apparent. This model tends to excessively brighten small parts of the frame, while in other situations it dims the entire scene too much. The effect of calibration is undeniable, and in terms of color accuracy, C69K / Q6C gains a lot. Unfortunately, certain limitations resulting from local dimming management simply cannot be overcome.

The Samsung S95F offers a noise reduction feature that smooths tonal transitions. It works very effectively, but in practice, it can be too aggressive. Materials of lower quality – such as older recordings or videos from YouTube – become soft and plastic when this feature is turned on, resembling an image digitally smoothed in a graphics program. Unfortunately, this also causes the natural film grain, which often adds authenticity to the image, to disappear. Fortunately, the TV does not lose too many fine details, such as in skin textures or elements of the surroundings. Therefore, this feature is best used with caution – depending on preferences, one can achieve a smooth image, but less natural, or one that is more faithful to the original. In our opinion, the most universal choice is the “Standard” setting.

The image scaling performs significantly better. The TV handles lower resolution materials well – even 576p content looks quite decent, although a slight blockiness can be noticed. Overall, the effect is very good, although it is somewhat inferior to what Sony Bravia 8 (II) or LG G5 can achieve. It's also worth mentioning a small imperfection of the S95F – in older materials, overscan may occur, causing a slight cropping of the left edge of the image.

In terms of image scaling, TCL C69K / Q6C performs quite well. Lower quality content is displayed acceptably, and thanks to the lack of overscan issues, the image is presented in full without any cropping. However, one shouldn't expect miracles – very low-quality materials won't gain a new life here, as the image processor has its limitations.

On thin lines and details, one can see characteristic jitter, indicating a lack of more advanced image enhancement algorithms. It's also a pity that the C69K / Q6C lacks the function for smoothing tonal transitions. As a result, in older movies or video materials, color banding can be noticeable and may become distracting during longer viewing sessions.

The Samsung S95F demonstrates phenomenal motion fluidity. The panel itself operates at a native 4K resolution with a refresh rate of up to 165 Hz, and combined with QD-OLED organic technology, it delivers incredible results. Sports and games look amazing – the image is fast, dynamic, and very natural. Additionally, the built-in motion smoother and motion blur reduction system allow you to adjust the character of the image to your preferences. You can opt for a more "frame" effect with visible film structure or a smooth, theatrical performance. Every viewer will find a setting that suits them.

The use of a 144 Hz panel in TCL C69K / Q6C is a significant advantage in this price range. It represents an important step forward compared to its predecessor (C655 PRO), which only offered 60 Hz at 4K. The difference is particularly noticeable when watching sports or playing games – the ball, players, or dynamic action in games are displayed more clearly and without losing details. An interesting feature is also the ability of the panel to operate at 240 Hz (which the manufacturer does not officially mention) – we will return to this topic in relation to the PC gaming mode. TCL has also added a feature for movie fans: “Motion Clarity.” This allows users to adjust the picture to their preferences using two simple sliders. We can either keep the visible film frame or opt for very smooth, "

The same advantages of low motion blur and excellent motion fluidity characteristic of OLED panels are just the beginning, as the Samsung S95F was designed with gamers in mind. The manufacturer has equipped it with four HDMI 2.1 ports – although limited to a bandwidth of 40 Gb/s, in practice, this has no impact on compatibility with consoles or PCs. We get a complete set of gaming features: variable refresh rate (VRR), automatic game mode (ALLM), as well as a very well-implemented HGiG standard, which allows HDR titles to appear as their creators intended. The whole thing is complemented by the Game Bar – a clear settings hub where we can preview and change all key picture parameters with one movement. The proprietary motion smoother Game Motion Plus also deserves praise, as it can smooth out animation, which is particularly useful in productions running at 60 frames, where stability is not always exemplary. Although support for Dolby Vision in games is lacking, it is hard to consider this a serious drawback – Samsung compensates for it with other solutions. This is one of the best, if not the best, gaming TVs available today on the market.

TCL C69K / Q6C is a television that can boldly be called equipment created with gamers in mind. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there's a practical Game Bar, which is a panel with the most important settings right at hand – useful when we want to quickly change something during gameplay (e.g., aspect ratio: Yes, it’s possible!). The wide range of VRR, reaching up to 240 Hz, is noteworthy. This option is primarily for PC gamers who will lower the resolution below native 4K. In that case, the TV can spread its wings and show additional smoothness, especially in fast esports titles. For consoles, we stick to the classic limit of 120 Hz, but the possibilities are still quite broad. The only drawback is slight motion blur that can sometimes be seen in dynamic scenes. Other than that, C69K / Q6C offers everything gamers expect from a television.
