Philips PUS8359 (VA) vs Philips PUS8209

The Philips PUS8359 has low brightness levels; however, dynamic tone mapping works surprisingly well, making it worth praising!

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 best factory mode for fidelity to the source material was the "Film" mode, which we used during our tests. As with all factory modes in televisions, it has flaws, and we’ll now examine what went wrong in both SDR and HDR materials. In both cases, the white balance showed an excessive dominance of green and red, resulting in a yellowish tint across the entire image. This caused issues such as yellowed whites and problems with skin tones. This was clearly illustrated on the "ColourChecker" palette, where each tested sample shifted towards warmer equivalents. The foundation of the image lies in contrast and black levels, represented by gamma charts and the EOTF curve. Looking at the gamma chart, we saw a real rollercoaster, with both elevated and lowered gamma. The elevated gamma caused visibility issues in blacks, while the lowered gamma led to a dramatic drop in contrast. In this context, the EOTF curve performed significantly better, as it only mildly brightened the image.

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.

Philips offers a wide range of image calibration tools in its higher-end and more affordable models. We used these tools, but the process was not as straightforward as many might expect. While we adjusted the white balance, significantly improved the gamma, and refined the EOTF curve in both SDR and HDR content, the deltaE errors remained extremely high. Several factors contribute to this situation, including the limited coverage of the DCI-P3 colour gamut and the unit's maximum brightness in HDR materials.

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.

In this paragraph, we will take a look at two functionalities. We will once again look at the function responsible for tonal transitions, but we will also check how the television handles image scaling. The option responsible for smooth gradation is called "Distortion Reduction." As we have established, it quite effectively smooths out imperfections. However, we need to point out two things: we cannot enable it for HDR material and it blurs details in films.

The tested television cannot boast the best image scaling. There is a noticeable overall blurriness of the image, but what is worse, it blurs details. This is particularly visible on the branches and the model's hair. Additionally, a characteristic white halo can often be seen surrounding characters.

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 Philips PUS8359 is not the best choice for watching sports. This is primarily due to the absence of even a basic motion smoothing feature, which given the price point, is not entirely surprising. Additionally, the television uses a VA panel, which, while offering high contrast, is not known for its sharpness or fast response times. As demonstrated in our analysis, fast-moving scenes often result in noticeable blurring, a common issue with this type of panel.

Although it is not an ideal option, the TV can be used for sports viewing with some compromises, particularly regarding motion sharpness. It's also worth noting that films are prone to stuttering since the TV lacks any form of motion smoothing, even the most basic functionality.

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.

Unsurprisingly the Philips PUS8359/12 offers only the most basic support for consoles. When connecting a console, users can rely on features like VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). VRR is particularly commendable, as even some higher-end models can struggle with this functionality.

A noteworthy addition is the implementation of a dedicated GameBar, which allows for on-the-fly adjustments without needing to exit the game, minimising unnecessary distractions. This feature also provides options to tailor gameplay for individuals with disabilities, making it a highly commendable inclusion.

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.
