Philips OLED769 vs TCL C655 / C69B (55"-85")

Philips OLED769 performs quite well, especially in movie scenes with small light points. The television surprises with its brightness, reaching around 800 nits, which is an impressive result. This means that small light sources, like street lamps at night or stars in the sky, are vivid and full of detail. However, the biggest challenge for this model is the scene with a full-screen sun glare. In such moments, the brightness drops to around 250 nits, which isn’t very impressive. This is a typical issue with cheaper OLED displays, which struggle to maintain high brightness across the entire screen.

Overall, the quality of the HDR effect in TCL C655 / C69B looks quite promising. The average value in the test patterns is around 450 nits, which already allows you to feel the light effects and better image dynamics. However, as mentioned earlier, this effect may be somewhat subdued by slight differences in bright and dark shades, resulting from the lack of local dimming technology. However, the DCI-P3 colour gamut coverage of 94% deserves high praise, and this is possible due to the use of a quantum dot (QLED) panel. This makes the colours vibrant and well-reproduced when watching HDR content.

The "Film" mode turned out to be the best factory setting in terms of fidelity to the original material, and it was on this setting that we based our tests. However, like other factory modes, it was not without its flaws. Let’s take a closer look at what exactly went wrong in the SDR and HDR materials.

In both cases, the white balance was disturbed by excessive dominance of green and red colours. This phenomenon created a yellowish tint that spilled over the entire image, leading to issues such as yellowed whites and unnatural skin tones. These problems were clearly highlighted on the "ColourChecker" palette, where each of the samples was shifted towards warmer shades.

As for contrast and brightness, in the Philips OLED769, we can look at two key graphs: Gamma for HD content and the EOTF curve for 4K HDR content. In the case of the first graph, the gamma value is below the optimal level of 2.4, resulting in the bright parts of the image being lightened. This means that bright elements may be somewhat overexposed, losing detail and depth. Meanwhile, the EOTF curve for 4K HDR content performs really well. The graph shows that the television effectively reproduces details in both the brightest and darkest parts of the image, translating to a realistic and dynamic representation of scenes.

The TCL C655 / C69B television offers a film mode that has been tested for colour reproduction quality. Although this mode is called film mode, it unfortunately has quite a few errors that the director would certainly not want to see when filming their work. Starting with image analysis, it's worth looking at the white balance – both in HD content and 4K HDR, the white balance has significant issues. In both cases, the red colour dominates, resulting in colours that are too warm, with an overall pink or yellow tint. This can be seen in the image below from the film "Star Wars." The Colour Checker test confirms these errors – the colour samples stray into incorrect shades, affecting the overall colour fidelity. The brightness characteristics are a lesser issue. However, they are not without flaws either. The gamma chart shows a strong spike at the beginning, which can cause the image to be overly bright, and the EOTF curve responsible for brightness in 4K HDR content also has significant fluctuations – it's evident how the television tries to maintain appropriate brightness, but it doesn't always succeed effectively.

After professional calibration, Philips OLED769 truly shines in terms of colour accuracy. The television has been completely rid of any yellow tint in both HD and 4K content. The Colour Checker test confirms that deltaE errors are minimal, occasionally exceeding 2, which means we can talk about almost perfect renderings of the director's vision.

When it comes to contrast, the situation is equally impressive. For 4K materials, there wasn't much to improve from the start, while the gamma graph has been significantly enhanced. As a result, dark and bright parts of the image are represented with greater accuracy, leading to realistic and dynamic scene reproduction.

The calibration has unlocked the full potential of this television, both in terms of colour and contrast. Philips OLED769 now offers vivid, natural images of high quality that will delight any user, whether they're watching movies or using other multimedia.

After calibrating the movie mode of the television TCL C655 / C69B , the white balance has been adjusted, and the colours look as they should – which is confirmed by only slight deviations in the Colour Checker test. The gamma is really good, which ensures that the television shouldn't have any issues with brightness in low-resolution material. Unfortunately, a similar EOTF characteristic is still noticeable, which is a natural occurrence in televisions that do not have local dimming – they simply struggle to "shine" brighter in a given part of the screen. Despite this design limitation, which cannot be bypassed, we recommend making adjustments in the settings, as the overall colour presentation looks really very good.

When it comes to lower quality materials, the distortion reduction in the Philips OLED769 does well at smoothing tonal transitions, especially at the minimum setting. It's worth noting that at this setting, film grain isn't blurred, which is a pleasant surprise, as such negative phenomena often occur with other manufacturers. Overall, it's quite a decent solution. However, it should be noted that this setting doesn't work in HDR mode, where gradation issues are much more pronounced. In HDR mode, the television struggles with smoothing tonal transitions and may present more noticeable distortions and noise, reducing image quality in dynamic scenes.

As for digital processing, the Philips OLED769 performs well. The model in the picture isn’t overly jagged, and the branches in the background lack the characteristic artifacts. The television achieves this effect by avoiding artificial sharpening, which may be an advantage for some users. However, others may find this less appealing, as they prefer a more vivid, sharper image rather than a subtle effect. This effect can be mitigated by using a higher setting for the "Sharpness" parameter.

Television TCL C655 / C69B handles tonal transitions in low-quality materials fairly well. The "Gradual Smoothing" feature on low settings effectively smooths out tonal transitions, but it also blurs important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps to maintain the natural look of the image. In terms of digital processing, the television adds artificial sharpness, which some users who prefer a sharper image might appreciate. However, for those who prefer a softer look, this may be a drawback. Another downside is that the image has been significantly cropped due to the so-called overscan, which reduces the field of view and cuts off the edges of the image.

Philips OLED769 features a multi-level motion smoother called "Motion Style," which will please users who value the ability to adjust motion fluidity in films. With this function, the image can be set to appear more stuttery or fluid, reminiscent of a theatrical effect. It's a great solution for those who want to tailor the displayed content to their visual preferences. Gamers will also not be disappointed, as the television, like most OLEDs, is equipped with a 120Hz panel. This ensures extraordinary fluidity and dynamic imagery. Unfortunately, Philips OLED769 does not have the BFI (Black Frame Insertion) feature, which could further enhance the smoothness and clarity of motion. Despite this limitation, the television still offers excellent visual experiences for both cinema lovers and gamers. This is definitely one of its strong points.

The television C655 / C69B is equipped with a 4K@60 Hz panel, which means it's best suited for watching movies and less dynamic content. It also features a "Flicker Reduction" function, allowing users to adjust the smoothness of the image – they can choose whether they prefer smoother motion or a more cinematic, frame-like effect. The television can also adapt to lower resolutions, such as Full HD and 2K at 120 Hz, which will surely please gamers by offering a smoother image at the cost of resolution. It’s worth noting that this feature is available in sizes starting from 55"+. Additionally, the largest variant, 98", is equipped with a 144Hz panel with full motion smoothing.

Philips OLED769 has been designed with gamers in mind, offering full compatibility with consoles and the highest quality gameplay. The television received the maximum rating in this category, providing everything your heart desires. With HDMI 2.1 ports fully supporting ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), the TV ensures smooth and hassle-free gaming. ALLM automatically switches the television to low latency mode, and VRR eliminates stuttering and screen tearing, resulting in smoothness and stability in gameplay. The Dolby Vision feature for gamers is another advantage, although it only works at 60 Hz. Most casual gamers will probably not feel the lack of a higher refresh rate, however, more demanding users may have some reservations. It allows for enjoying a dynamic range of tones and realistic images, enhancing the gaming experience. PC gamers will also not be disappointed, as the Philips OLED769 offers full compatibility with Nvidia graphics cards, thanks to support for G-Sync. This technology synchronizes the TV's refresh rate with the graphics card, eliminating tearing and stuttering, leading to excellent image smoothness.

Philips OLED769 is a television that perfectly meets the needs of gamers, offering a wide range of advanced features and technologies that significantly enhance game quality and user comfort.

The TCL C655 / C69B TV offers an almost perfect set of features for gamers, supporting all the key technologies. It has an ALLM feature that automatically switches the TV to low latency mode, significantly improving responsiveness and minimising signal lag, which is especially important during dynamic gameplay. The VRR feature allows synchronisation of the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay.

The TV also supports Dolby Vision in gaming mode, ensuring better colour and contrast reproduction in games that support this format, and the Game Bar enables quick access to gameplay-related settings, such as response time, latency level, and other parameters. Unfortunately, the C655 / C69B does not support 4K resolution at 120 Hz (the 98" variant is the exception), which may be disappointing for more demanding gamers seeking the ultimate smoothness in high-resolution games. However, if we can forgo 4K, the TV offers support for Full HD and 2K at 120 Hz, providing a smoother image and serving as a great alternative for those who prefer higher refresh rates at the expense of resolution.
