TCL C655 / C69B (43" - 50") vs Philips PUS8209

The quality of the HDR effect in the TCL C69B / C655 television is quite average. With a brightness level of 350 nits, although not the worst, it still doesn't allow for a full enjoyment of HDR effects, which require higher luminance to showcase their power. Additionally, despite the application of a quantum dot coating (QLED), the television offers an average coverage of the wide DCI-P3 colour gamut at 91%, which may limit its richness of colours in HDR content.

Unfortunately, this is where the problems begin. A maximum brightness of 280 nits is definitely too low to feel the true effect of HDR. In practice, the image resembles standard SDR more, so it’s hard to speak of deeper visual experiences. On the positive side, the colour gamut coverage is commendable – 91.4% DCI-P3 is a score that will be sufficient for most films. It must also be said that the image is stable and there are no issues with sudden changes in brightness or colours. Overall, HDR on this television is more of a formality than an actual added value. If we are looking for genuine HDR thrills, this model may not meet expectations.

The television TCL C69B / C655, tested in movie mode, unfortunately does not meet expectations in terms of colour accuracy. Although movie mode suggests better representation, it has almost nothing in common with film. There are many errors evident, particularly in white balance – for both HD and 4K HDR content – where the dominance of the blue colour is very noticeable. For the viewer, this means that the image becomes unnaturally cool, affecting the overall perception of colours and the visual impression. The colour checker confirms these errors, showing that colours shift towards cooler shades.

As for brightness characteristics and the related contrast, gamma is very unstable for the material, which can make the image slightly darker. The EOTF curve for the 4K material shows some errors, with significant deviations towards the end of the graph, which negatively impacts the reception of darker parts of the image.

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 clear problems. In the case of HD content, the white balance is characterised by a strong dominance of red, which causes the picture to be significantly warmer than it should be in reality. The brightness characteristic (gamma), although correct in the mid-tones, has serious issues at the beginning and end of the curve. Drops in the shadows cause a loss of detail in the dark areas, and blowouts in the bright areas make some elements look unnatural.

For high-quality 4K HDR content, the situation reverses. In this case, blue dominates, leading to an artificial enhancement effect, reminiscent of unnatural retail settings. Such an image looks unattractive 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, causing the image to appear too dark, robbing the depth and detail of HDR content.

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

After calibration, the movie mode on the TCL C69B / C655 television improves in quality. The greatest improvement can be seen in tonal quality, and the white balance presents itself much better – with no major errors. We will no longer see an excessive dominance of cool tones. Gamma has also been improved, leading to a more stable representation of brightness and contrast. However, due to limitations in the form of the television's average colour palette, Colour Checker tests for 4K materials did not achieve remarkable results. Despite these technological limitations, the image has become more authentic, positively affecting the reception of film content.

After calibration, the white balance for HD and 4K content has significantly improved. Although we have not achieved a perfectly flat characteristic, the effect is definitely better than before. The picture on the television no longer appears artificially warm or excessively 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, responsible for brightness in 4K HDR material, has been stabilised, eliminating problems with excessive dimming of the image. In the colour palette test, some imperfections can still be noticed due to average coverage of the wide colour gamut, which is a limitation of the equipment itself. Nevertheless, the final effect is clearly better than before calibration – the image looks more natural and approaches the expectations of the Filmmaker mode.

The "Gradual Smoothing" function works very well on the TCL C69B television and, surprisingly, does not remove desirable effects such as film grain – unlike some solutions from other manufacturers. When it comes to image scaling, unfortunately, it looks poor. The television artificially sharpens the image, causing the edges of objects to be quite jagged. This state of affairs may appeal to some users who prefer a more "hard" look to the image, but it is not an ideal solution for those who value naturalness and fluidity of details.

The television offers a "Distortion Reduction" feature that effectively improves the gradation of tonal transitions, especially when set to the minimum level. Unfortunately, this comes at a cost – the feature simultaneously smooths out details such as the texture of materials. On the positive side, it is worth noting that the operation of this option does not negatively affect 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 certain elements, such as branches or fine details, which can lower the quality of reception. Despite these minor imperfections, the overall experience of scaling is satisfactory.

The TCL C69B / C655 television in its smallest variants offers decent, though not perfect, results in terms of motion smoothness. For films, the television features a "Flicker Reduction" function that allows adjustment of motion smoothness on a scale from 1 to 10. With this option, we can tailor the appearance of the image to our cinematic or more theatrical preferences (with either lower or higher speed).

The 60 Hz panel in the Philips PUS8209 is mainly suitable for watching films, but there is still a sense of something missing. The television does not offer any motion smoother that would allow users to adjust the fluidity of the picture to their individual preferences, which can be disappointing for some users.

The TCL C69B / C655 television in its smallest variants offers a range of features dedicated to gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the television to low latency mode, improving responsiveness and minimising delays in control. VRR allows the screen refresh rate to synchronise with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay. Dolby Vision for gamers ensures better colour and contrast reproduction in games that support this format, resulting in enhanced picture quality. Meanwhile, Game Bar provides quick access to game settings and monitors key parameters such as input lag.

However, the television has certain limitations that may affect gaming comfort. The 60 Hz panel does not allow for displaying signals with higher refresh rates, which may impact the smoothness of the image in fast-paced games. The lack of support for G-Sync technology for PCs may also be noticeable when gaming on a computer, especially in demanding, fast-paced titles.

The Philips PUS8209 offers basic features 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 smoothness and image precision. 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.
