Samsung OLED S95D vs TCL C69K / Q6C

Samsung S95D offers excellent HDR performance, delivering consistent effects across all scenes exceeding values of 1500 nits, except for the fifth, where brightness drops to 800 nits. Despite this, the television maintains a high level of picture quality. A significant advantage of QD-OLED technology is its ability to maintain high brightness even in the smallest elements against a black background, which is rare in LCD and mini LED televisions. As a result, every scene dazzles with strong lighting effects, regardless of the size of the illuminated area. Only in the brightest scenes with large light areas does brightness slightly drop, which is typical even for standard OLEDs produced by LG. Additionally, the quantum dot coating has achieved an unprecedented high coverage of the BT.2020 colour gamut at 88%.

In terms of brightness, TCL C69K / Q6C is a moderate model. In optimal film conditions, it shows its full potential, achieving a maximum of around 600 nits. In scenes with large, intense light sources, the HDR effect can be truly satisfying, providing a cinematic shimmer. However, it should be noted that when managing backlight zones, there are situations where parts of the image become dimmed, and sometimes they are barely visible. This suggests that there is still a lack of proper optimisation of the algorithms; however, considering the technical parameters in this price range, the design itself still presents very well.

On the Samsung S95D, the mode that best reproduces colours is the Filmmaker mode. We conduct all our tests in this mode. Although initially, the picture in this mode may appear slightly warmer to the viewer, it provides significantly more detail compared to the standard or dynamic mode, which is always oversaturated and artificial. The Filmmaker mode is therefore the most closely aligned with the vision of filmmakers and ideal for watching high-quality content. It is worth noting, however, that the factory settings are not perfect, despite dealing with premium segment equipment. The image may contain certain errors that affect the overall quality of the displayed scenes. An example is drops in red colour in the white balance, both in HD and HDR content. Colour Checker tests showed that the hues lean towards cooler tones. The image is dominated by blue hues, and the entire colour spectrum is distorted. As can be seen in the picture below, the little boy from the film appears in cooler tones, making him look less natural. When it comes to the brightness characteristics for HD content, it is quite accurate, although there are minor errors. The biggest problem arises when displaying 4K HDR content. The EOTF curve, which seems appropriate at first glance in test patterns, shows that the television sometimes "messes" with the image in real film scenes. This causes the picture to be slightly brightened in some scenes and darkened in others.

Samsung S95D offers quite good factory colour reproduction, but it has some shortcomings that may require calibration to fully utilise the potential of this television. The process is recommended to achieve the most natural and immersive image possible.

The Filmmaker mode, which has made its debut 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 daily film and series viewings. Unfortunately, as is often the case, best does not mean perfect. In SDR material, the image proved to be too warm, with a pronounced red tint in the white balance. We had the opposite impression with HDR content – here the image became cooler than it should, due to an excess of blue. Additionally, there is the characteristic of brightness, which at times resulted in overexposure. In practice, this translated into quite noticeable errors in colour tests, which is difficult to accept in a mode branded as "from the creators."

How much can the picture quality of a television change after calibration? After performing calibration on the Samsung S95D, the white balance was significantly improved, eliminating any major errors, which allowed for a more natural and harmonious colour reproduction. In the case of 4K content, there are only minor imperfections, which do not affect the overall picture quality. Thanks to calibration, viewers can now enjoy more balanced tones, allowing for a better representation of the filmmakers' intentions. The contrast has also improved, and the gamma shows even better results. This means that the differences between the light and dark areas of the image have become more pronounced, translating into better depth and detail in scenes. As a result, shadows gained more detail, and bright areas are no longer overwhelming, providing a more realistic visual experience. However, it should be noted that the EOTF curve is slightly below the expected level, which may affect how the television handles dynamic scenes. Nonetheless, after calibration, the overall picture quality has significantly improved, and viewers can now enjoy a visual experience that is more in line with the filmmakers' intentions. The television handles subtle tonal transitions and contrast better, making it more suitable for watching films and high-definition programmes. Ultimately, the picture after calibration is closely aligned with reference quality, making the visual experience even more satisfying.

Through white balance correction, we were able to significantly reduce the tendency of C69K / Q6C to distort colours, which yielded a very good final result. After calibration, the issue of excessive warming of scenes in SDR and excessive cooling of the image in HDR disappeared. However, it is worth analysing the brightness characteristics more closely. While in SDR content it is hard to have major objections – the image looks really good, especially in older films, TV programmes or on YouTube – it performs significantly worse in the case of HDR content. Analysis of the EOTF curve suggests that everything is fine, yet in practice (EOTF in films) the limitations of the design itself become apparent. This model has a tendency to excessively brighten small parts of the frame, only to overly dim the entire scene in other situations. The effect of calibration is therefore undeniable, and in terms of colour reproduction, C69K / Q6C gains a lot. Unfortunately, certain limitations arising from local dimming management simply cannot be bypassed.

How does the television handle tonal transitions in lower-quality materials? Generally speaking, the S95D performs exceptionally well. On the screen with the light bulb, there are virtually no transitions between shades of grey, making it one of the best televisions we have tested in this regard.

Regarding digital processing, the entire image — from branches to model figures — has been well rendered, without any jagged edges or heavily visible contours. However, we must draw attention to one issue: the image is slightly cropped. Nevertheless, the television performs excellently, and details in lower-quality materials are still noticeable and well-defined.

In terms of image scaling, TCL C69K / Q6C performs quite well. Lower quality content appears acceptable, and thanks to the lack of overscan issues, the image is displayed in full without any cropping. However, one should not expect miracles – very low-quality materials will not gain a second life here, as the image processor has its limitations.

Thin lines and details exhibit characteristic tearing, which reveals the absence of more advanced image enhancement algorithms. It is also a pity that the C69K / Q6C lacks a tone transition smoothing feature. As a result, in older films or video materials, banding of colours can be visible and may become distracting during prolonged viewing.

The Samsung S95D television, equipped with a refresh rate of 120 Hz (and even 144 Hz in the appropriate PC configuration), offers excellent motion smoothness. Samsung provides a variety of image sharpness settings on a ten-point scale, allowing users to adjust the display according to their preferences - whether the image should be more cinematic/frame-like or more theatrical/smooth. In UFO tests, the OLED matrix shows its advantages, eliminating any blurring. The lightning-fast pixel response means that dynamic movements are reproduced with unparalleled precision.

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 in 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 loss of detail. Another interesting feature is the panel's ability to work 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 Samsung S95D TV is perfectly suited to the needs of gamers, offering four HDMI 2.1 ports that support key features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). The HDMI 2.1 ports do not provide full bandwidth of 48Gb, but they are still sufficient for achieving appropriate resolution and smoothness. Thanks to these technologies, gamers can enjoy smoother and more responsive gameplay, which significantly impacts comfort and performance during intense gaming sessions. One of the biggest advantages is the Xbox app, which allows for cloud gaming without the need for a console. Through it, gamers can access a wide range of titles directly on the TV, enjoying high image quality and smooth gameplay. Additionally, the S95D offers a Game Bar feature that enables easy management of game settings, including quick adjustments of parameters such as changing the aspect ratio, which can be extremely useful in various games and gaming modes. It is also worth mentioning the support for G-Sync and FreeSync, which is a huge plus for users of Nvidia and AMD graphics cards. Despite the lack of support for Dolby Vision, the TV still offers excellent features that make it an ideal choice for console gaming enthusiasts. Overall, the S95D combines modern technologies with outstanding picture quality, creating a complete package for any gamer.

TCL C69K / Q6C is a television that can confidently be described as 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 is a practical Game Bar, which is a panel with the most important settings conveniently at hand – useful when we want to change something quickly during gameplay (e.g. screen aspect ratio: Yes, it can be done!). The wide range of VRR, reaching up to 240 Hz, is particularly noteworthy. However, this option is mainly for PC gamers who will operate below the native 4K resolution. In that case, the television can spread its wings and show additional smoothness, especially in fast-paced e-sports titles. For consoles, we stick to the classic limit of 120 Hz, but even so, the capabilities are truly extensive. The only downside is a slight ghosting that can occasionally be seen in dynamic scenes. Other than that, C69K / Q6C offers everything that gamers expect from a television.
