Philips OLED769 vs TCL C655 Pro

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.

In the HDR effect quality category, the television TCL 655 PRO shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoying HDR effects, which can be clearly seen in scenes such as the first one from the movie Life of Pi or the final shot from The Meg. However, the limited number of dimming zones causes some issues. While in bright scenes the television performs better than its lower model, in more demanding scenes, such as the second and fourth scenes from Sicario 2, it struggles more. The dimming algorithm aims for deep blacks, but at the cost of brightness – which at those moments can cause a drop in brightness of even half. In these more challenging scenes with small elements, it's hard to find any praise, and the HDR effect resembles SDR. Nevertheless, the coverage of the colour palette deserves recognition, which, like in the version without the PRO suffix, is at a very good level.

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.

Each of our TV tests is conducted in movie mode, which usually offers the best colour reproduction. However, even this mode is not free from issues, as we noted in the TCL 655 PRO model.

In the case of HD content, the white balance clearly shifts towards red, and this effect becomes particularly noticeable in a scene from Star Wars, where the white elements of the scenery take on a pink hue. For 4K HDR material, the situation looks better, but there is a tendency to overly emphasise the colour blue. As a result, the image can give a sense of artificial sharpness, which proves to be uncomfortable for the eyes over a longer period. The brightness characteristics also leave much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, making the overall presentation appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we have detailed in the paragraph regarding HDR effects.

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 TCL 655 PRO television, there is a noticeable improvement in white balance, where the tendency for the screen to be overly pink has been completely eliminated, which was previously noticeable in factory mode. The picture has taken on more natural tones, especially in white and bright elements, which positively affects the overall image perception. Regarding brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image appear washed out. Nevertheless, there are still some issues with the EOTF curve, which are difficult to eliminate due to the television's construction and its limited number of backlight zones. These limitations prevent achieving perfect results in this regard. However, despite this minor fault, the overall effect after calibration is truly outstanding, providing high picture quality and very good colour reproduction.

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.

The TCL 655 PRO television handles tonal transitions quite well in lower-quality material. The "Gradual Smoothing" feature at low settings effectively smooths tonal transitions, but this comes at the cost of losing some essential details, such as the texture of objects. On the plus side, it doesn't negatively affect film grain, which helps maintain a natural look to the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a bolder image. However, individuals who favour a softer, more subtle look may find this a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and cuts off the edges of the frame. This can be problematic in certain scenes - for example, news tickers.

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 TCL C655 PRO television is equipped with a 4K display with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows for adjusting the smoothness of the picture, giving the user the choice between smoother motion and a cinematic, frame-by-frame effect. Furthermore, the television performs well with lower resolution content, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will surely appeal to gamers who can enjoy a smoother image, albeit at the cost of lower resolution.

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 PRO TV offers an almost perfect set of features for gamers, supporting all key technologies that significantly enhance gameplay comfort. The ALLM feature automatically switches the TV to low-latency mode, improving responsiveness and minimising signal delay – particularly important in fast-paced titles. VRR synchronises the screen refresh rate with the frame rate generated by the console, eliminating screen tearing and ensuring smoother gameplay.

Support for Dolby Vision in game mode enables more detailed colour and contrast representation in games that support this format, while the Game Bar provides quick access to essential settings, such as response time and latency level. Unfortunately, the model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those willing to forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for high refresh rate enthusiasts.
