Philips PUS7009 (IPS) vs Philips PUS8359 (IPS)

In terms of HDR quality, PUS7009 (IPS) performs very poorly. A brightness level of 250 nits doesn't allow for enjoyment of HDR effects, and the image resembles more of a standard SDR. There’s no talk of dynamic effects or vivid bursts of light. The coverage of the DCI-P3 colour gamut is only 75%, which is definitely insufficient. The lack of full colour coverage means that the colours are not as vibrant as they should be, resulting in a flat and unimpressive image. There are no aspects to commend this model in the context of HDR.

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.

The television was tested in movie mode, which – despite its name – does not provide correct image display. The white balance in both 4K HDR and HD/SDR content is characterised by drops in red, making the image cooler and the colours lose their natural warmth. The gamma brightness characteristics and EOTF curve confirm that the television has issues maintaining appropriate brightness – it boosts it significantly, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where everything looks as if it has a milky filter applied. Additionally, the limited coverage of a wide colour gamut also does not promote quality – colour checker attempts indicate significant colour variations, making it difficult to achieve faithful image reproduction.

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.

After calibration, the picture has significantly improved, especially in terms of white balance, which is now more stable, and the shades have taken on a natural quality, eliminating the earlier impression of a rather cool picture. The calibration has brought noticeable benefits in terms of tonality – the shadows and midtones are now more realistic, and the whole seems more harmonious. Unfortunately, hardware limitations still affect the quality of the image. The brightness characteristic remains problematic, despite our efforts, and due to poor coverage of the DCI-P3 and BT.2020 colour gamut, delta E errors are still at a high level. Although calibration has improved some aspects, the television still does not allow for complete satisfaction.

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.

If we talk about tonal transitions in low-quality material, the feature called "Distortion Reduction" (set to "minimum") effectively improves the gradation, eliminating undesirable tonal transitions. However, this setting on Philips TVs is quite aggressive – while it doesn't blur grain or high-quality material, it may introduce unwanted effects and blur elements that should remain sharp with poorer signals.

In terms of image scaling, Philips PUS7009 performs reasonably well. A significant advantage is the absence of cropped edges, meaning no overscan, which allows for displaying the full frame without loss. The image is noticeably improved, making characters and backgrounds, such as the model or branches in the background, look fairly detailed and natural, even with lower quality signals. Although the scaling is not perfect, as it can remove desired details in the distance, the results are good enough to satisfy most users.

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.

Philips PUS7009 does not have any motion smoothing features in films, which means we cannot choose whether the picture should be more choppy or more cinematic. These features could improve more dynamic scenes. As for motion blur, despite using a 60Hz IPS panel, the situation looks quite good. The response time between pixels is better than in versions with a VA panel, which keeps motion blur at an acceptable level and does not significantly affect the viewing comfort of dynamic scenes.

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.

In terms of compatibility with consoles, Philips PUS7009 is suitable for casual gamers. Despite using HDMI 2.0, the TV offers access to features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Game Bar. ALLM automatically switches the TV to low latency mode, allowing for faster responses while gaming, while VRR dynamically adjusts the refresh rate to reduce screen tearing. The Game Bar is a tool that provides quick access to game settings and real-time parameter monitoring - although we believe it looks the weakest compared to competing Game Bars.

Unfortunately, more demanding gamers may be disappointed. The Philips PUS7009 does not support advanced HDR formats in games or high refresh rates, due to the use of a 60 Hz panel. The lack of support for these features limits the TV's ability to deliver smooth and fully detailed experiences during fast-paced gameplay.

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.
