Philips OLED910 vs TCL C69K / Q6C

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 branded as "META OLED". It is this panel that allows for over 2000 nits of brightness in films, which not long ago was completely unachievable in OLEDs. The way the television handles full-screen scenes flooded with bright light also deserves high praise. Usually, in OLEDs, brightness drops significantly, but here it remains at a great level – around 1400 nits. These values are almost reference-level, and combined with 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 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.

Unfortunately, when it comes to colour reproduction straight out of the box, the Filmmaker mode on the OLED910 really falls short. The television overemphasises the blue colour and at times it looks almost like a shop mode. It gives the impression that the manufacturer hasn't quite calibrated the device properly. The result is that colours appear unnatural, and the overall look resembles a slightly exaggerated display from a store showcase. HDR content looks much better, where apart from a slight loss of detail in blacks, there’s hardly anything to complain about. The problem is that in everyday viewing, it’s actually SDR materials that matter the most – and on the OLED910, they just look poor and significantly deviate from what we would expect from a television of this class.

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".

Fortunately, it quickly turned out that it wasn't the panel causing the problems, but the way Philips factory-tuned the OLED910. After calibration, the television showcased its full potential, and only then could we see what the new panels from LG Display were truly capable of. We primarily corrected the white balance and brightness characteristics, successfully taming the excessive blue and giving the image a natural look. 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 ideal and colours presented in line with the creators' intent. In SDR content, the effect was stunning, 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 be confidently referred to as reference-grade in terms of colour accuracy.

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 previously visible colour connections can be largely mitigated thanks to a feature called "distortion reduction." Similar to the OLED820, it’s best to set it to medium level, as it then provides quite decent results – smoothing unwanted tonal transitions while not taking away too many details from the image. Although at times the effect may be a bit too aggressive, in everyday viewing, this function can be considered useful.

When it comes to image scaling, the OLED910 performs really well. The test material with the model showcased a characteristic soft look typical of Philips – at times almost too soft – but at any moment this can be adjusted with the sharpness slider to tailor the image to your own preferences. It’s also a plus that the television has no issues with overscan, which still occurs in some competitors' models. It’s a minor detail, but it’s pleasing as 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 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.

OLED910 is a TV 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 matrix used in it is capable of that. On the other hand, such a bonus will mainly benefit PC gamers, as for everyday use, the most important thing is the 120 Hz refresh rate, which is fully sufficient. Combined with the advantages of the OLED matrix – lightning-fast pixel response times and the absence of motion blur, the picture is impeccably sharp and fast, even in dynamic action scenes. The traditional motion smoother from Philips called “Motion Style” also deserves praise. We can easily adjust it to our own preferences: the “Smoothness” slider is for movies and allows you to choose between a more “framey,” cinematic character and a smooth, theatrical image. Meanwhile, the “Motion Blur Reduction” slider is intended for sports; here, it’s worth setting it to the maximum value so that the image is clear and sharp during very fast shots.

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, "

The OLED910 is fantastic for gaming. It supports 144 Hz, so if someone has a powerful PC, they'll easily make the most of that potential. For consoles, the most important thing is still 120 Hz, and everything works smoothly here. It has VRR, an automatic game mode, and even Dolby Vision in games along with HGiG mode, so we pretty much get a full package of gaming features. Philips also added a Game Bar, which is like a quick menu that shows basic information and allows you to enable a few handy features. It might not look as modern as the competition, but it works and does its job. The only downside is the number of HDMI 2.1 ports. There are only two, which can be quite disappointing in this class of television. If someone connects two consoles and something extra to the eARC - like a soundbar (which doesn't really make sense in this model, but more on that in the sound section), they'll have to do a bit more figuring around. Other than that, though, the OLED910 has everything we expect from a gaming TV.

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.
