Philips OLED910 vs TCL C69K / Q6C

The OLED910 is simply an absurdly bright television for an OLED. All thanks to the new panel from LG Display, the Tandem RGB OLED, which Philips has dubbed its "META OLED." It is this panel that allows for over 2000 nits of brightness in films, which not long ago was completely unattainable in OLEDs. The television also deserves high praise for how it handles full-screen scenes drenched in bright light. Generally, in OLEDs, brightness drops significantly during such scenes, but here it remains at an excellent level – around 1400 nits. These are almost reference values, and combined with the excellent colour reproduction at 99% DCI P3 and 82% BT.2020, it gives us an HDR effect that can confidently be called one of the best in the world.

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.

Unfortunately, when it comes to colour reproduction straight out of the box, the Filmmaker mode on the OLED910 performs really poorly. The television overemphasises the blue colour, and at times it looks almost like a shop display mode. This gives the impression that the manufacturer hasn’t quite tuned the device properly. The effect is that the colours look unnatural, and the whole thing resembles a somewhat exaggerated display from a market exhibition. HDR content is presented much better, where, apart from a slight loss of detail in the blacks, there’s not much to complain about. The problem is that in everyday viewing, it’s the SDR materials that matter the most – and on the OLED910, they simply look poor and fall well short of what we would expect from a television of this class.

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."

Fortunately, it quickly turned out that it was not the panel causing the problems, but rather the way Philips factory-calibrated the OLED910. After calibration, the television displayed its full potential, and only then could we see what the new panels produced by LG Display were truly capable of. We primarily adjusted the white balance and brightness characteristics, successfully taming the excessive blue and giving the image a natural appearance. The final effect can be described as excellent. Errors on the Color Checker palette rarely exceeded a value of 3, which in practice means an image close to perfection and colours presented in accordance with the creators' intent. In SDR content, the effect was outstanding, and in HDR, the improvement was even more noticeable – gradients became cleaner, and colours fuller and more accurate. After calibration, the OLED910 transformed from a disappointing television into equipment that can confidently be referred to as a reference in terms of colour quality.

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.

The previously visible colour banding can largely be mitigated thanks to a feature called "distortion reduction." Like in the OLED820, it is best set to a medium level, as it then produces fairly decent results – smoothing out unwanted tonal transitions while not taking away too much detail from the image. Although at times the effect may be slightly too aggressive, this function can be considered useful for everyday viewing.

As for image scaling, the OLED910 performs really well. The test material featuring a model had a soft look characteristic of Philips – at times almost too soft – but this can be easily corrected with the sharpness slider, allowing you to adjust the image to your own preferences. It's also worth noting that the television has no issues with overscan, which still occurs in some competitor models. It's a small detail, but it's pleasing because it means that all content, even the oldest, is displayed as it should be.

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.

OLED910 is a television with a refresh rate of 144 Hz. It’s a bit of a shame that Philips didn’t opt for 165 Hz, as we know that the panel used is capable of that. On the other hand, such a bonus would mainly benefit PC gamers, as in everyday use, the most important refresh rate is 120 Hz, which is fully sufficient. Combined with the advantages of the OLED panel – lightning-fast pixel response time and the absence of motion blur, the image is impeccably sharp and quick, even in dynamic action scenes. The traditional motion smoother from Philips, called “Motion Style,” also deserves praise. We can easily adjust it to our preferences: the “Fluidity” slider is responsible for films and allows you to choose between a more “filmy,” cinematic character and a smooth, theatrical image. Meanwhile, the “Motion Blur Reduction” slider is intended for sports, where it’s worth setting it to the maximum value to ensure that the image is clear and distinct during very fast shots.

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 OLED910 is fantastic for gaming. It supports 144 Hz, so if someone has a powerful PC, they can comfortably utilise that potential. On consoles, the most important thing is still 120 Hz, and everything works perfectly here. There's VRR, an automatic gaming mode, and even Dolby Vision in games and HGiG mode, so we really get a full package of gaming features. Philips has also added a Game Bar, which is a quick menu that displays basic information and allows you to enable a few useful things. It may not look as modern as the competition, but it works and fulfils its purpose. The only downside is the number of HDMI 2.1 ports. There are only two, which can be quite disappointing for a TV in this class. If someone connects two consoles and something additional through eARC - like a soundbar (which doesn't make much sense in this model but I'll discuss that in the paragraph about sound) - they'll have to do some adjustments. Other than that, the OLED910 has everything we expect from a gaming television.

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.
