TCL C655 / C69B (55"-85") vs Philips PUS8209

Overall, the quality of HDR performance in TCL C655 / C69B looks quite promising. The average value in test patterns is around 450 nits, which already allows one to feel the effects of lighting and better image dynamics. However, as mentioned earlier, this effect may be partially suppressed by slight differences in bright and dark colors, resulting from the lack of local dimming technology. However, the DCI-P3 color gamut coverage of 94% deserves high praise, and this is made possible by the use of a quantum dot (QLED) panel. As a result, colors are vibrant and well-reproduced when watching HDR content.

Unfortunately, this is where the problems begin. A maximum brightness of 280 nits is definitely too low to feel the true HDR effect. In practice, the image resembles standard SDR more, so it's hard to speak of deeper visual experiences. On the plus side, the color gamut coverage is commendable – 91.4% DCI-P3 is a result that will be sufficient for most films. It must also be noted that the image is stable and there are no issues with sudden changes in brightness or colors. Looking at the overall picture, HDR on this TV is more of a formality than an actual added value. If we are looking for true HDR emotions, this model may not meet expectations.

The TCL C655 / C69B television offers a movie mode that has been tested for color reproduction quality. Although this mode is called movie mode, unfortunately, it has quite a few errors that a director would certainly not want to see while recording their work. Starting with image analysis, it's worth looking at the white balance - both in HD and 4K HDR content, the white balance has significant errors. In both cases, the red color dominates, making the colors too warm, and overall it has a pink or yellow tint. This can be seen in the picture below from the movie "Star Wars." The Colour Checker test confirms these errors - the color samples stray into inappropriate shades, affecting the overall color fidelity. A minor issue is the brightness characteristic. However, it is also not free of flaws. The gamma chart shows a strong spike at the beginning, causing the image to be overly bright, and the EOTF curve responsible for brightness in 4K HDR material shows significant fluctuations as well – it is visible how the television tries to maintain proper brightness, but it does not always succeed effectively.

Philips PUS8209 offers many picture modes, but the best among them, without a doubt, is the Filmmaker mode. Despite its proud name, it has its clear issues. In the case of HD content, the white balance is characterized 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 the midtones, has serious problems at the beginning and end of the graph. Drops in the shadows lead to a loss of details in dark areas, and highlights in bright areas make some elements look unnatural.

For high-quality 4K HDR content, the situation reverses. In this case, blue dominates, leading to an effect of artificial image enhancement, reminiscent of unnatural store settings. Such an image looks unappealing and inconsistent with the creators' intentions. An additional problem is the EOTF curve, responsible for brightness in HDR materials. It deviates significantly from the reference chart, making the image appear too dark, robbing the depth and detail of HDR content.

Against this background, the errors in the Color Checker test and deviations in color palette reproduction are exceptionally large, which negatively impacts the overall image quality. The Filmmaker mode, although the best among the available options, requires significant corrections to fully deliver the director's vision.

After calibrating the movie mode of the TCL C655 / C69B television, the white balance has been equalized, and the colors look as they should – which is confirmed by only slight deviations in the Colour Checker test. The gamma is really accurate, which means the television should not have issues with brightness in low-resolution materials. Unfortunately, a similar EOTF characteristic is still visible, which is a natural phenomenon in televisions that do not have local dimming – they simply struggle to “shine” more brightly in a given part of the screen. Despite this structural limitation that cannot be overcome, we recommend adjustments in the settings, as the overall color representation looks really very good.

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

The TCL C655 / C69B television handles tonal transitions in low-quality materials pretty well. The "Gradual Smoothing" feature at a low setting effectively smooths tonal transitions, but at the same time, it blurs important details, such as the texture of objects. On the positive side, it does not negatively affect film grain, allowing for a natural look of the image. As for digital processing, the television adds artificial sharpness, which may appeal to some users who prefer a sharpened image. However, for those who prefer a softer look, this may be a disadvantage. A downside is also that the image has been quite heavily cropped by so-called overscan, which reduces the field of view and cuts off the edges of the image.

The television offers a "Distortion Reduction" feature that effectively improves the gradation of tonal transitions, especially when set to the minimum level. Unfortunately, it comes at a price – the feature also smooths out details like the texture of materials. On the plus side, 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, one can sometimes notice issues with aliasing on some elements, such as branches or fine details, which can lower the quality of the reception. Despite these minor imperfections, the overall experience of scaling is satisfactory.

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

The 60 Hz panel in the Philips PUS8209 is mainly suited for watching movies, but there is also a certain sense of dissatisfaction here. The TV does not offer any motion smoothing feature that would allow adjusting the smoothness of the picture to individual preferences, which may be disappointing for some users.

The television TCL C655 / C69B offers an almost perfect set of features for gamers, supporting all the most important technologies. It has an ALLM feature that automatically switches the television to low latency mode, significantly improving responsiveness and minimizing signal delays, which is particularly important during dynamic gameplay. The VRR feature allows for synchronizing the screen refresh rate with the number of frames generated by the console, eliminating the tearing effect and ensuring smoother gameplay.

The television also supports Dolby Vision in game mode, providing better color reproduction and contrast in games that support this format, and the Game Bar enables quick access to gameplay-related settings such as response time, delay level, and other parameters. Unfortunately, C655 / C69B does not support 4K resolution at 120 Hz (with the exception of the 98" variant), which may be disappointing for more demanding gamers who expect the highest fluidity in high-resolution games. However, if we are willing to forgo 4K, the television offers support for Full HD and 2K at 120 Hz, providing a smoother image and being a great alternative for those who prefer a higher refresh rate at the expense of resolution.

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

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