TCL C655 Pro vs Philips PUS8209

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.

Unfortunately, this is where the problems start. A maximum brightness of 280 nits is definitely too low to experience the true effect of HDR. In practice, the image resembles standard SDR more, so it's hard to talk about deeper visual experiences. On the plus side, the colour gamut coverage is 91.4% DCI-P3, which will be sufficient for most films. It's also worth noting that the image is stable and there are no issues with sudden brightness or colour changes. Overall, HDR on this television is more of a formality than an actual added value. If we're looking for genuine HDR emotions, this model may not meet expectations.

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.

Philips PUS8209 offers many picture modes, but the best of them, without a doubt, is the Filmmaker mode. Despite its proud name, it has its distinct problems. For HD content, the white balance is characterised by a strong dominance of red, causing the image to be significantly warmer than it should be in reality. The brightness characteristic (gamma), although correct in mid-tones, has serious issues at the beginning and end of the graph. Drops in shadows result in a loss of detail in dark areas, and spikes in bright areas make some elements look unnatural.

For high-quality content in 4K HDR, the situation reverses. In this case, blue dominates, leading to an artificial image boost effect, reminiscent of unnatural retail settings. Such an image looks unappealing and does not align with the creators' intentions. An additional problem is the EOTF curve, responsible for brightness in HDR materials. It deviates significantly from the reference graph, causing the image to appear too dark, stripping depth and detail from HDR content.

Against this backdrop, the errors in the Color Checker test and deviations in colour palette reproduction are exceptionally large, which further negatively affects the overall image quality. The Filmmaker mode, while the best among those available, requires substantial corrections to truly convey the full vision of the director.

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.

After calibration, the white balance for HD and 4K content has significantly improved. While we haven't achieved a perfectly flat characteristic, the result is definitely better than before. The image on the television no longer appears either artificially warm or overly cold, which significantly enhances the naturalness of the displayed content. The brightness characteristic (gamma) has also been adjusted – the most significant issues at the beginning and end of the graph have been mitigated. The EOTF curve, which is responsible for brightness in 4K HDR materials, has been stabilised, eliminating problems with excessive dimming of the image. In the colour palette test, some imperfections can still be seen due to the average coverage of the wide colour gamut, which is a limitation of the hardware itself. Nevertheless, the final result is clearly better than pre-calibration – the image looks more natural and approaches the expectations for Filmmaker mode.

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.

The television offers a “Distortion Reduction” feature that effectively improves the gradation of tonal transitions, particularly when set to the minimum level. Unfortunately, this comes at a cost – the feature also smooths out details like material textures. On the plus side, it’s worth noting that the operation of this option does not negatively affect the film grain, which remains intact.

As for image scaling (upscaling), the television generates a plastic, soft image that generally looks pleasant. However, in the background, issues with aliasing of certain elements, such as branches or small details, can sometimes be noticed, which may decrease the quality of the reception. Despite these minor imperfections, the overall experience of scaling is satisfactory.

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.

The 60 Hz panel in the Philips PUS8209 is mainly suited for watching movies, but here you can also feel a certain shortcoming. The television does not offer any motion smoothing that would allow you to adjust the fluidity of the picture to individual preferences, which for some users may be disappointing.

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.

Philips PUS8209 offers basic features useful for gamers, such as variable refresh rate (VRR), automatic low latency mode (ALLM), and Game Bar, which makes managing settings easier.

Unfortunately, due to the 60 Hz panel, the TV will not meet the expectations of more demanding gamers who are looking for higher fluidity and precision of image. Additionally, this model does not support any HDR mode dedicated to gaming, such as HGiG or Dolby Vision, which further limits its capabilities in this regard.
