Philips PUS8359 (VA) vs Philips PUS7009 (VA)

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

In terms of HDR effect quality, Philips PUS7009 performs very poorly. A brightness level of 250 nits does not allow enjoyment of HDR effects, and the image resembles more of a standard SDR. There is no talk of dynamic effects or vivid light bursts. The coverage of the DCI-P3 color palette is only 75%, which is definitely insufficient. The lack of full color coverage means that the colors are not as vibrant as they should be, resulting in a flat and unconvincing image. There are no aspects to praise this model in the context of HDR.

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.

The TV 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 characterized by drops in red color, causing the image to appear cooler and colors to lose their natural warmth. The gamma brightness characteristics and EOTF curve confirm that the TV has trouble maintaining appropriate brightness – it boosts it significantly, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where the overall appearance looks as if covered with a milky filter. Additionally, limited coverage of a wide color gamut also does not favor quality – color checker tests indicate significant color fluctuations, making it difficult to achieve faithful image reproduction.

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 image has significantly improved, especially in terms of white balance, which is now more stable, and the shades have gained naturalness, eliminating the previous impression of an excessively cool image. The calibration has brought noticeable benefits in terms of tonality – shadows and midtones are now more realistic, and the overall picture appears more harmonious. Unfortunately, hardware limitations still affect the quality of the image. The brightness characteristics remain problematic despite our efforts, and due to the poor coverage of the DCI-P3 and BT.2020 color 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.

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.

When it comes to tonal transitions in low-quality material, the function called "Distortion Reduction" (setting "minimum") effectively improves gradation, eliminating ugly tonal transitions. However, this setting on Philips televisions is quite aggressive – it does not blur grain or good quality material, but with a poorer signal, it can introduce unwanted effects and blur elements that should remain sharp.

In terms of image scaling, Philips PUS7009 performs decently. A major advantage is the absence of cropped image edges, meaning no overscan, which allows for displaying the full frame without loss. The image is noticeably improved, making characters and backgrounds, such as models or branches in the background, look quite 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 for most users to be satisfied.

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.

Philips PUS7009 does not have motion smoothing features, which means there is no option to adjust the image for a more choppy or smoother, cinematic effect. Such features could positively influence the reception of dynamic scenes. As for motion blur, this model is equipped with a 60 Hz VA panel, which produces slightly worse results than the IPS panel variant. The VA panel introduces a minimally greater motion blur, although the differences are not significant and should not pose a problem for most viewers.

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.

In terms of compatibility with consoles, Philips PUS7009 is likely to satisfy casual gamers. Although equipped with HDMI 2.0, it offers features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Game Bar. ALLM automatically switches the TV to low-latency mode, which speeds up reactions during gameplay, while VRR adjusts the refresh rate to minimize screen tearing. The Game Bar allows quick access to game settings and monitoring of key parameters, although it visually falls short compared to competing solutions. However, more demanding gamers may feel a sense of dissatisfaction. Philips PUS7009 does not support advanced HDR formats in games, and the 60 Hz panel limits the ability to display smooth and detailed images in dynamic scenes, which may not satisfy fans of fast-paced action games.
