Philips PUS8359 (IPS) vs Panasonic Z95A

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.

Panasonic Z95A shows class when it comes to HDR performance. In luminance tests, it achieves a level of 1800 nits, which has a real impact on movie watching. Scenes from Life of Pi or Gemini Man look fantastic – the television effortlessly reproduces details and the intensity of bright spots, making a strong impression with its power. In more demanding moments, like the final scene from The Meg, you can see how bright light floods the screen. In such moments, brightness drops, which is typical for organic panels. Nevertheless, a result around 1000 nits can still be considered excellent, still providing very good picture quality. Additionally, the television offers great coverage of wide colour gamuts – up to 98.6% for DCI-P3 and 74.5% for BT.2020. This means that colours are not only vibrant but also deeply saturated, allowing full appreciation of the richness of details, especially in HDR scenes. Such coverage makes colours look more realistic, and the HDR effect gains intensity and accuracy. All this impressive HDR effect is thanks to MLA technology, which enables such high luminance and excellent image detail. With it, the Panasonic Z95A offers HDR at a level that truly makes a difference.

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.

The best picture mode on the Panasonic Z95A is undoubtedly the Filmmaker mode. This mode offers quite good image reproduction, but it is not without certain flaws that need addressing. Primarily, the white balance, for both 4K and HD content, tends to be dominated by red and blue hues. This leads to a slight pink tint in the image, particularly noticeable in bright, white scenes. Such discrepancies can be seen in the comparative image below, which illustrates the issue well. The Colour Checker test also confirms these inaccuracies, showing slight shifts of dots towards the mentioned shades.

In terms of gamma brightness characteristics, it performs very well, with only minor issues when brightening small details. A greater challenge arises with the EOTF curve, which is responsible for controlling brightness in 4K HDR content. Here, there is a slight boost in brightness above the reference value, which sometimes makes the image overly bright, especially in more demanding scenes. While the Filmmaker mode is definitely the best choice on the Z95A, these aspects require refinement to fully harness the television's potential.

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, Panasonic Z95A showcases its full potential, delivering an almost perfect image. The television offers extensive adjustment capabilities, which we have fully utilised. The white balance post-calibration is absolutely flawless, and the errors in SDR content at 0.5 are at an exceptionally reference standard. The same goes for 4K HDR content – the screen tint has been completely eliminated, and the white balance is now exemplary.

The colour palette and Colour Checker test confirm the excellence of the calibration. Errors below 2 are a result that will satisfy both professional calibrators and cinema-quality image enthusiasts. Significant changes have also occurred in the brightness characteristics – the EOTF curve has been aligned, eliminating previous issues with excessive brightness. Additionally, a small error in gamma has been reduced.

Before calibration, the image was acceptable, but now it's in a completely different league. It's a true feast for the eyes, and the quality is hard to compare to anything else. Once fine-tuned, the Panasonic Z95A becomes a true master of colour reproduction.

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.

In the case of lower quality materials, the "Gradation Smoothing" function is responsible for smoothing tonal transitions. The best results are achieved with an intermediate setting – while they are not spectacular, the function works correctly and does not introduce unwanted effects into the image. It can be evaluated as average, but sufficient for improving the quality of tonal transitions.

As for digital processing, or upscaling, the picture looks surprisingly good. It is flexible and pleasant to the eye, which makes lower quality content, such as standard television or YouTube, look quite decent. However, minor issues can be observed, such as "aliasing" on edges, e.g. branches in the background. Nevertheless, this does not significantly affect the overall viewing experience, and the television handles these materials in an acceptable manner.

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.

Panasonic Z95A, with a 144 Hz panel, offers excellent image smoothness. For movies, there is an "Intelligent Frame Creation" feature that allows for improved smoothness and reduction of blurring. Users have two sliders at their disposal: "Motion Blur Reduction" – responsible for clearer and sharper details in fast-moving scenes. "Film Smoothness" – adds smoothness by creating additional frames between the originals, making motion appear more fluid and natural with the effect of "soap opera"

As a result, viewers can adjust the settings to their own preferences. Movies and less dynamic content look smooth and natural, which should satisfy most users.

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.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in support for gamers. The television offers practically everything you can expect from a device in this range. Support for ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate) ensures smoothness and no tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and the additional support for resolutions other than 4K provides greater flexibility, which is a big plus for gamers using various configurations.

Also noteworthy is the unique and rather specific "Game Bar." Its bubble interface stands out from the competition and allows quick adjustment of key settings such as VRR, brightness level, or picture mode, without the need to interrupt gameplay.

However, in this class of devices, there has been a slight disappointment – Panasonic Z95A only offers two HDMI 2.1 ports instead of four. This is definitely too few for a premium television, especially in times when many people have more than one device requiring full HDMI 2.1 support, such as a next-gen console or a high-end computer. In this category, it's hard to accept, especially given the high aspirations of this model. Despite this, the television is an excellent choice for gamers, offering versatility and functionality at the highest level.
