TCL C655 Pro vs Philips OLED909

In the HDR effect quality category, the TCL 655 PRO television shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoyment of HDR effects, which is clearly visible in scenes such as the first from the movie Life of Pi or the last frame from The Meg. However, the limited number of dimming zones causes some problems. 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. The dimming algorithm aims for deep blacks, but at the cost of brightness – which in these moments leads to a decrease in brightness by as much as half. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles rather SDR. Nonetheless, the coverage of the color palette deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

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.

Each of our TV tests is conducted in movie mode, which usually offers the best color reproduction. Nevertheless, even this mode is not free from problems, as we noted with 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 excessively enhance the blue color. As a result, the image can appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristic also leaves much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, causing the overall presentation to look washed out. Additionally, the EOTF curve reveals significant issues with the reproduction of very small elements - they are excessively dimmed, as we detailed in the paragraph regarding HDR effects.

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.

After calibrating the TCL 655 PRO television, a noticeable improvement in white balance can be observed, having completely eliminated the tendency for the screen to have an excessive pink hue, which was previously visible in factory mode. The image has taken on more natural tones, especially in white and bright elements, positively affecting the overall perception of the picture. As for brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image look washed out. Nevertheless, there are still some issues with the EOTF curve that are difficult to eliminate due to the design of the television and its limited number of dimming zones. These limitations prevent achieving ideal results in this regard. However, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high image quality and very good color reproduction.

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.

The TCL 655 PRO television handles tonal transitions in lower-quality materials quite well. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, this comes at the cost of losing some important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps maintain the natural look of the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a more vivid image. However, those who favor a softer, subtler look may find this to be a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - e.g., news tickers.

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.

The TCL C655 PRO TV is equipped with a 4K panel with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows users to adjust the fluidity of the image, giving them the choice between smoother motion or a cinematic, choppy effect. Moreover, the TV handles lower resolution content well, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy smoother images, albeit at the cost of lower resolution.

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 TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all key technologies that significantly improve the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in better responsiveness and minimized signal delays – particularly important in dynamic titles. VRR synchronizes the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and thus guaranteeing smoother gameplay.

Support for Dolby Vision in game mode allows for more detailed color and contrast reproduction in games that support this format, while the Game Bar provides quick access to important settings such as response time or latency level. Unfortunately, this model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those who can forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for enthusiasts of higher refresh rates.

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.
