Philips PUS8359 (IPS) vs Panasonic W95B

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

The Panasonic W95B is truly a bright screen, capable of achieving a peak luminance of around 1400 nits. In brighter, well-lit film scenes, this value translates to spectacular HDR effects that can make a big impression. However, knowing our test setup, you can probably see that in very demanding shots – such as the moon in the distance or the lights of a helicopter in the scene from Sicario 2 – the television does not impress. In such situations, brightness drops to around 200 nits, which makes the HDR effect much less noticeable. This happens because Panasonic prioritises maintaining deep blacks, not illuminating the background – for many users, this shouldn't be a cause for concern. However, it is important to remember that in these moments the image begins to resemble SDR content. The coverage of the colour palette also deserves praise, as it reaches about 93% of the DCI-P3 space thanks to the use of a PFS filter (also known from QLED technology). As a result, most films look very good in terms of saturation and colours, preserving the cinematic character of the image.

The most faithful factory mode in terms of compliance with the source material turned out to be "Film", which was used in our tests. Nevertheless, like other factory modes, it also had its flaws. In both SDR and HDR materials, we noticed issues with white balance, where the dominance of green and red resulted in a yellowish tint. This effect was particularly noticeable in the form of yellowed whites and unnatural skin tones. The "ColourChecker" palette test showed that every colour had shifted to warmer tones, affecting colour reproduction accuracy. A key aspect of the image is also contrast and brightness, which can be assessed by analysing gamma charts and the EOTF curve. On the gamma chart, we noticed significant deviations – both excessively high values, which 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.

In Filmmaker mode, the Panasonic W95B offers an image with quite accurate colour reproduction, although it is not without minor imperfections. The white balance slightly veers towards red, which may cause a subtle warming of the image, and the gamma curve is slightly elevated, making the screen appear a bit brighter. It is good that the manufacturer included this mode – even in factory configuration, it provides a reasonably natural appearance for films. However, knowing how susceptible Panasonic televisions are to calibration, we decided to see how much the image could be improved after professional tuning.

Philips, both in 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, but despite these efforts, the deltaE errors were still 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 result. Although the overall presentation is much better, the design features of the television did not allow us to achieve spectacular results.

After professional calibration, the Panasonic W95B shows what it is truly capable of. Colour errors have mostly dropped below values of 2–3, making them practically invisible to the human eye. It was also possible to correct the excess red in the white balance, which has resulted in the image no longer having a slight pink tint, and details in dark areas are no longer lost due to excessive dimming in the gamma. In HDR content, the improvement is also noticeable – colour saturation is now more stable and does not shift so markedly towards blue as it did before. This is truly an excellent television for watching films and series in the highest possible quality. While we know that Mini LED screens are not always perfect for this, the W95B is a perfect example that with proper fine-tuning, an effect close to OLEDs can be achieved.

In this paragraph, we will take a look at two functionalities. Once again, we will examine the feature 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 irregularities. However, we must point out two things: we are unable to enable it for HDR materials, and that it blurs details in films.

The tested television cannot boast the best image scaling. The overall blurriness of the image is quite noticeable, 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 terms of image processing, the Panasonic W95B performs excellently. The proprietary processor responsible for digital image processing effectively upscales lower resolution content to 4K, preserving a great deal of detail and a natural appearance of contours. The final effect is impressive – the upscaling here is at a truly high level, and Full HD content can look surprisingly good. The way the television smooths tonal transitions in low-quality materials is also noteworthy. The algorithm does not operate as aggressively as in some competing models, but as a result, it does not cause a loss of detail or blur film grain.

Philips PUS8359 is not the best choice for watching sport. The lack of even basic motion smoothing functionality means that the image during fast-moving scenes is not adequately clear. Despite the use of an IPS panel (43 and 55'), which theoretically should offer better sharpness than VA panel variants, there is no noticeable improvement regarding blurring. In pictures with fast movement, the figure of the alien is clearly blurry, indicating that the television struggles to maintain sharpness in dynamic shots.

The 144 Hz panel used in the Panasonic W95B offers excellent fluidity, although in practice, due to the appearance of television content or the limitations of new generation consoles, it is worth observing its performance at a refresh rate of 120 Hz. In this mode, the television performs superbly – despite being a VA panel, which is not known for the fastest pixel response times, motion blur here is minimal and difficult to detect with the naked eye.

In terms of compatibility with consoles, Philips PUS8359 is mainly suited for occasional gamers. Although the television is equipped with an HDMI 2.0 port, it offers features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and Game Bar. ALLM automatically switches the television to low latency mode, making quicker reactions easier during gameplay, while VRR smoothly adjusts the refresh rate, eliminating screen tearing issues. The Game Bar provides quick access to game settings and real-time monitoring of parameters; however, in our opinion, it performs worse compared to the competition's solutions.

However, more demanding gamers may feel unsatisfied. 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 television's capabilities in delivering smooth and detailed experiences during fast, dynamic gameplay.

Aside from the previously mentioned drawback related to the VRR mode, in which local dimming does not work, the Panasonic W95B is a true gaming monster. The television offers practically everything that gamers can expect – perhaps except for four HDMI 2.1 ports, as there are only two available. Onboard, we find an auto low latency mode (ALLM), properly implemented HDR modes for gamers, including HGiG, as well as support for Dolby Vision in games. It is all complemented by an interestingly designed Game Bar, presented in the form of circles. While it may not be the most visually attractive, it serves its purpose – allowing quick access to key game parameters and adjusting settings without entering the system menu.
