SAMSUNG S95F (TANDEM OLED 83") vs TCL C69K / Q6C

The Samsung S95F in the 83-inch variant with a Tandem OLED panel also enchants with its 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 TV easily achieves brightness levels surpassing 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 constructions.

The limitations of organic panels only emerge in full-screen scenes completely filled with white. In the case of this model, for example, in the final scene of the film The Meg, brightness drops to around 1000 nits – slightly lower than in the smaller QD-OLED variants, where the result hovered around 1400 nits. Nevertheless, we are still talking about an outstanding result, unprecedented in OLED TVs of this size. The colour reproduction is equally impressive. The new Tandem OLED panel nearly catches up to QD-OLED TVs, offering excellent coverage of a wide colour gamut. The results are slightly weaker than those of QD-OLED, but in practice, they still provide an image whose intensity and naturalness of colours are hard to compare with any other television.

In terms of brightness, TCL C69K / Q6C is a moderate model. In 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, giving a cinematic glow. However, it's important to keep in mind that when managing the backlight zones, there are situations where parts of the image are dimmed, and at times become barely visible. This suggests that there is still a lack of proper optimization of the algorithms, although considering the technical parameters in this price range, the overall construction still looks very good.

The best picture mode right out of the box is undoubtedly Filmmaker Mode. This mode has been present in Samsung televisions for several years and is intended to reproduce the image as faithfully as possible to the creators' vision. In SDR material, it performs reasonably well, though not without flaws. The image is slightly dimmed, and the white balance tends to shift towards red and blue, resulting in a slight pinkish tint on the screen. Average colour errors hover around values of ΔE 3–4, which is on the borderline of what most people can detect with the naked eye.

The limitations are much more apparent with HDR content. Here, a slight excess of blue in the white balance isn't such a big issue – the real obstacle is how the television manages brightness. In many scenes, the image looked as if it had been blown out, and details in the blacks could completely vanish. The final effect didn't do justice to what such a device is capable of, leading to significant colour inaccuracies. It's hard to understand why such a factory characteristic was chosen, as the perception of HDR in this rendition was definitely not what it should have been.

The Filmmaker Mode, which has been introduced in this year's TCL TVs (including the C69K / Q6C), is definitely the best choice "to start with". This is the mode we recommend for everyday movie and series viewing. Unfortunately, as is often the case, best does not mean perfect. In SDR materials, the image turned out to be too warm, with a strong red tint in the white balance. The opposite impression was had with HDR content – here the image became cooler than it should have been, due to an excess of blue. Additionally, there is the brightness characteristic, which at times resulted in overexposures. In practice, this translated to fairly noticeable errors in color tests, which is difficult to accept in a mode branded as "by the creators".

After calibration, the S95F shows what it can really do. The white balance has been straightened out, and minor inaccuracies have been corrected, making the image in SDR content look nearly exemplary. Colour differences have fallen below the level that the human eye can detect – looking at the screen, one just gets the impression of complete naturalness and harmony of colours.

In HDR, the improvement is equally noticeable. The TV handles brightness much better, and there’s no longer the 'blowing out' of the entire frame. Bright scenes are more controlled, and blacks retain more detail, though sometimes a slight brightening of the overall image can still be noticed. However, this doesn’t change the fact that after calibration, the S95F delivers an image that can confidently be called one of the best on the market – regardless of whether we’re watching movies in SDR or spectacular productions in HDR.

Through white balance adjustment, we were able to significantly reduce the tendency of ChooseTV C69K / Q6C to distort colours, which resulted in a very good final outcome. After calibration, the problem of excessive warming of scenes in SDR and over-cooling of the image in HDR disappeared. However, it's worth analysing the brightness characteristics more closely. While in SDR content there are few complaints – the picture looks really good, especially in older films, TV programmes, or on YouTube – it performs 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 actual construction become evident. This model tends to excessively brighten small parts of the frame, while in other situations, it darkens the entire scene too much. The effect of calibration is therefore undeniable, and in terms of colourimetry, ChooseTV C69K / Q6C gains a lot. Unfortunately, certain limitations arising from local dimming management simply cannot be bypassed.

The Samsung S95F model features noise reduction, aimed at improving the fluidity of tonal transitions. Its effectiveness is difficult 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 reminiscent of a painting effect thanks to this feature. The problem is that along with the noise, the natural film grain, which gives the image a cinematic quality, also disappears. Fortunately, the feature does not blur significant details, so its use is more a matter of preference. 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 videos look quite good, although 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 is noticeable that those models can extract a bit more from the image. However, one inconvenience to remember is that in the case of older films and photos, there is a problem with overscan, which causes a slight trimming of the left edge of the image.

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

On thin lines and details, there is noticeable jaggedness, which reveals the lack of more advanced image enhancement algorithms. It's also a shame that the C69K / Q6C lacks a feature for smoothing tonal transitions. As a result, in older films or video materials, color banding can be visible and may become distracting during extended viewing.

In the case of the 83-inch S95F with a Tandem OLED panel, the fluidity of motion 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 sport look fantastic. Additionally, the manufacturer has added a motion smoother and a motion blur reduction system, allowing each viewer to customise the picture to their own preferences – whether a more 'choppy', cinematic effect or a smooth, almost theatrical spectacle.

The use of a 144 Hz panel in TCL C69K / Q6C is a significant advantage in this price range. This 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 gaming – the ball, players, and dynamic action in games are displayed more clearly and without losing detail. An interesting feature is also the panel's ability to operate at 240 Hz (which the manufacturer does not officially mention) – we will revisit 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 own preferences using two simple sliders. We can either leave the visible film frame or opt for a very smooth one, "

Low motion blur and phenomenal motion fluidity, hallmarks of the OLED panel, 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 feel the slightest limitation here. Onboard is a full set of gaming features: variable refresh rate VRR, automatic game mode ALLM, and an excellently implemented HGiG standard, which allows you to enjoy HDR exactly as the creators intended. All this is complemented by Game Bar – an intuitive command centre where you can check and adjust the most important settings in seconds.

Particularly noteworthy is Game Motion Plus, Samsung's proprietary motion smoother. It can add additional fluidity to animations, which can be a lifesaver in games running at 60 frames, where stability doesn't always hold up. Yes, there's no support for Dolby Vision in games, 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 favourites for the title of the best gaming television on today's market.

TCL C69K / Q6C is a television that can confidently be called equipment designed for gamers. 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 within easy reach – handy when we want to change something quickly during gameplay (e.g., aspect ratio: Yes, it can be done!). The wide range of VRR, reaching up to 240 Hz, is noteworthy. However, this option is mainly for PC gamers looking to go below native 4K resolution. In this case, the television can spread its wings and show additional smoothness, particularly in fast e-sport titles. For consoles, we stick to the standard limit of 120 Hz, but even so, the possibilities are truly extensive. The only minor criticism is slight ghosting that can sometimes be seen in dynamic scenes. Other than that, C69K / Q6C offers everything gamers expect from a television.
