Philips OLED909 vs TCL C69K / Q6C

The Philips OLED909 impresses with the quality of its HDR effect, achieving up to 1500 nits of peak brightness in tested scenes. This is an excellent result, placing this television among the best OLED models on the market. The MLA matrix, also used in models like the Panasonic Z95A and LG G4, plays a key role here, allowing for exceptionally bright and detailed reproduction of dynamic scenes. However, it's worth noting that in the most demanding scene from the movie The Meg, the brightness drops to around 700 nits. This is a typical phenomenon in OLED technology, where intensely bright full-screen images cause a limitation of luminance. Nevertheless, the HDR effect still looks very good, and the television performs better than most competitors under similar conditions. The wide color gamut coverage also deserves praise. The OLED909 offers 95% coverage of DCI-P3, ensuring the television can display vivid and realistic 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.

Like other televisions, the Philips OLED909 has been tested for color reproduction in factory modes. The best mode turned out to be Filmmaker Mode, but despite its name, it is not free of flaws.

The biggest problem is the white balance. Both in HD and 4K HDR content, there is a noticeable dominance of green and red shades, which causes a distinct yellowing of the screen. This effect is particularly visible in test materials, for example in the scene with Tom Cruise in the foreground, where the difference compared to the calibrated image is very clear.

Regarding brightness characteristics, the gamma in HD materials was boosted too much - it was below the reference value of 2.4, which gave the image a "milky" filter and affected the overall clarity. In the case of 4K HDR content, we noticed the opposite phenomenon – there is a clear drop at the beginning of the EOTF curve, indicating problems with reproducing the smallest details in dark scenes. Although the Filmmaker mode offers acceptable quality, noticeable errors in white balance and brightness characteristics show that the television requires additional calibration to fully reveal its potential in color reproduction.

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.”

Philips OLED909 offers tools for image calibration, which significantly improves its quality. After calibrating the Filmmaker Mode, the television presents a much more natural color reproduction. The white balance after calibration looks very good. Although we noticed slight deviations in the blue hue in HD content, the errors fall within acceptable limits, and the image looks much better than in factory settings. The brightness characteristics, including gamma and EOTF, have also been distinctly improved. The television no longer has issues with excessive brightening or darkening of the image. Both dark and light details are now rendered correctly, making the image look very good in every scene. After calibration, the Filmmaker mode in the Philips OLED909 offers excellent image quality that will meet the expectations of even the more demanding users. The calibration fully utilizes the potential of this model.

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.

Philips OLED909 offers a distortion reduction feature aimed at smoothing tonal transitions. Unfortunately, the effectiveness of this feature leaves much to be desired. Setting it to "Medium" yields some results, but it comes with the risk of blurring essential details in the image. For this reason, we do not recommend using this option unless you are focused on mitigating visible artifacts at the expense of detail.

When it comes to image scaling, the television presents a very pliable image, which may appeal to viewers who prefer a softer image. Those expecting sharper clarity will also find a solution, as image scaling can be adjusted according to individual preferences in the settings.

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 Philips OLED909 with a 144 Hz panel offers excellent image fluidity, which should satisfy both movie lovers and gamers. Additionally, the television is equipped with a smoothing feature called "Motion Style," which allows precise adjustment of image fluidity to personal preferences. In the settings, we find two sliders: "Fluidity," which regulates the fluidity of motion in movies, and "Motion Blur Reduction," which helps eliminate minor artifacts and distortions in dynamic scenes. This feature works well, making even fast movements on the screen clear and readable.

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 Philips OLED909 is a television that meets practically all the requirements of gamers. Equipped with ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and support for Dolby Vision, it guarantees excellent gaming experiences. Additionally, the television offers very low input lag, ensuring that the response to player movements is instantaneous, which will be especially appreciated by fans of dynamic games.

The television easily supports any resolution at 120 Hz, and even higher refresh rates. The HGiG feature, responsible for the correct display of HDR content in games, works as it should, making the image in game mode balanced and tailored to the guidelines of console manufacturers.

The OLED909 also includes a Game Bar feature that allows for quick previewing and changing of game-related settings. Although the interface of this solution may seem less visually appealing than that of competitors, it serves its purpose well by offering all the most important options in one place.

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.
