Philips PUS8359 (IPS) vs Philips PUS8209

The quality of the HDR effect on the Philips PUS8359/12 television is also not impressive. A brightness level of 280 nits is too low, resembling standard SDR more than true HDR, which is clearly evident on the five tested test cards. Additionally, the television does not impress in terms of colour gamut coverage – just 76% DCI-P3 is a result that can be considered poor, especially compared to other models in a similar price range.

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.

The most faithful factory mode in terms of compliance with the source material turned out to be "Film," which was used in our tests. However, like other factory modes, it also had its drawbacks. Both in SDR and HDR materials, we noticed issues with white balance, where the dominance of green and red resulted in a yellowish hue. This effect was particularly evident in the form of yellowed whites and unnatural skin tones. The "ColourChecker" palette test showed that each colour was shifted towards warmer tones, which affected the accuracy of colour reproduction. A key aspect of the image is also contrast and brightness, which can be assessed by analysing the gamma charts and the EOTF curve. In the gamma chart, we observed significant deviations – both excessively high values that caused loss of detail in the shadows and excessively low values, which led to a drastic drop in contrast. Compared to gamma, the EOTF curve performed better, only slightly brightening the image, which had a less negative impact on overall quality.

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.

Philips, in both its cheaper and more expensive models, offers a wide range of tools for image calibration. We used them to improve the quality of the displayed image, although it was not as straightforward as it might seem. We managed to adjust the white balance, improve the gamma, and fine-tune the EOTF curve; however, despite these efforts, the deltaE errors remained at a very high level. The main causes were limited coverage of the DCI-P3 palette and low maximum brightness, which significantly affected the final outcome. While the overall presentation is much improved, the design features of the television did not allow us to achieve spectacular results.

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.

In this paragraph, we'll take a look at two functionalities. We'll once again examine the function responsible for tonal transitions, but we'll also check how the television handles image scaling. The option responsible for smooth gradation is called "Distortion Reduction". As we've established, it does a pretty good job of smoothing out inconsistencies. However, we must point out two things: we are unable to enable it for HDR content, and it blurs details in films.

The television being tested cannot boast the best image scaling. There is a noticeable overall blurriness in the image, but worse still, it blurs details. This is particularly evident on the branches and the model's hair. A characteristic white halo around the figures is also visible.

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.

Philips PUS8359 is not the best choice for watching sports. The lack of even basic motion smoothing features means that the picture in dynamic scenes isn't sharp enough. Despite using an IPS panel (43 and 55'), which theoretically should provide better clarity than VA panel variants, there’s no noticeable improvement in terms of motion blur. In photos of fast movement, it’s clear that the figure of the little green man is distinctly blurry, indicating that the TV struggles to maintain sharpness in dynamic shots.

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.

In terms of console compatibility, Philips PUS8359 is mainly suitable for casual gamers. Although the TV is equipped with an HDMI 2.0 port, it offers features such as Automatic Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and Game Bar. ALLM automatically switches the TV to low-latency mode, making quicker reactions during gaming easier, while VRR smoothly adjusts the refresh rate, eliminating screen tearing issues. The Game Bar provides quick access to game settings and ongoing parameter monitoring; however, in our opinion, it performs worse compared to competitors' solutions.

However, more demanding gamers may feel disappointed. Philips PUS8359 does not support advanced HDR formats in games or higher refresh rates, which is due to the use of a 60 Hz panel. These shortcomings limit the TV’s ability to deliver smooth and detailed experiences during fast-paced, dynamic gameplay.

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.
