Philips PUS8079 vs Panasonic Z85A

The Philips PUS8079 has a maximum brightness of just 202 nits in content with a wide tonal range, which is very low and makes it unsuitable for streaming movies and series in the highest quality. Additionally, using HDR with dynamic metadata doesn’t improve the situation, as the only HDR format available on this model is HDR10+, which is rare and has limited content support. The TV also uses WLED backlighting, which is not optimal and results in only 80% coverage of the DCI-P3 wide colour gamut. This limits the intensity of colours in HDR content.

The Panasonic Z85A is an OLED television, so you can expect great effects in movies right away. And indeed – our tests show that the WOLED panel can achieve around 800 nits of peak brightness in optimal conditions. This is a solid result that performs well in most demanding HDR scenes, allowing you to enjoy a dynamic and detailed image. However, like every OLED, the Z85A has its limits. In very bright scenes that cover the entire screen – like the final sequence from the movie The Meg – the television reduces brightness to about 400 nits. This is standard behavior for this technology, so if someone plans to watch movies in a brightly lit living room, it's worth keeping this in mind. The coverage of the DCI-P3 color gamut at 98% also deserves a big plus. As a result, the television delivers a wide range of colors that stand out with vibrancy and depth, and details in HDR scenes are sharp and precise. In short – the Panasonic Z85A provides a solid HDR effect that will satisfy any movie enthusiast.

The best factory mode for colour reproduction and fidelity to the director's vision on the Philips PUS8079 was the "Film" mode. However, this setting displayed significant discrepancies between the filmmaker's intent and the actual output. In both SDR and HDR materials (with HDR being less affected), the white balance was off, showing a blue tint similar to store displays, rather than pure whites. When it came to SDR materials, gamma was notably lowered, cutting into the already limited contrast and brightening the overall image. The EOTF curve in HDR content also showed a significant drop below the reference line, making HDR materials appear even darker. The colour accuracy in both SDR and HDR modes was poor, with high deltaE values indicating that the colours were far from their intended representation.

The Panasonic Z85A offers many picture modes, but the Filmmaker mode definitely stands out from the rest. It is rare for a television to be so well-tuned straight out of the box, and the unit we had the opportunity to test really impressed us positively.

However, there were some minor shortcomings. In the SDR signal, we noticed a slight deficiency in red and blue colors, which made the image have a cooler shade than it should. This is particularly evident in the comparative photo. Conversely, in 4K HDR materials, the situation was the opposite – the excess of red made the image seem warmer than the creators intended. In terms of brightness characteristics (gamma) and maintaining the appropriate EOTF curve, it is hard to find fault. There are some minor deviations, but they are so minimal that the average viewer is unlikely to notice them.

It is also worth emphasizing that our observations pertain to a specific unit of the television. Two identical models can differ from each other due to natural production variations. Nevertheless, the unit we had in hand is really solid and deserves praise. Now it's time for our calibration – we'll see if we can squeeze even more from this screen!

Fortunately, Philips incorporates advanced image correction tools across its televisions. SDR content benefited the most from these adjustments, with significant improvements in deltaE errors, white balance, and gamma. While the image still isn’t perfect, it is much more watchable, making it easier on the eyes during movie or series viewing. HDR content, however, was more challenging due to the television’s low luminance. While the EOTF curve and white balance improved, the corrections weren’t as effective as with SDR materials. It’s important to note that each unit may have different errors, some larger and some smaller, but the adjustments made were a step in the right direction.

The Panasonic Z85A offers truly wide possibilities when it comes to image settings, so we enthusiastically set about calibration. Although we mainly focused on white balance correction, the final effect exceeded our expectations. Both HD and 4K HDR content now present nearly perfect color reproduction, with minimal errors that are difficult to catch with the naked eye. Well-calibrated televisions are rare, and we must admit – it is truly gratifying. Although gamma and EOTF curve did not require drastic adjustments, we managed to further stabilize their characteristics across the entire brightness scale. After calibration, the Panasonic Z85A is a true gem for home cinema enthusiasts. The image is precise, colors are natural, and every scene looks exactly as the director intended.

Let us revisit the topic of tonal transitions, this time in the context of overall image quality enhancement. As shown in the photo on the left, the gradation improvement feature delivers excellent results. It provides multiple settings, each offering noticeable benefits without softening the film grain effect. Once again, it must be emphasised that this feature is the standout advantage of the tested television.

On the other hand, the television’s performance in image scaling leaves much to be desired. Fine details often appear heavily jagged, with a noticeable white halo around figures. Additionally, the significant artificial sharpening detracts from the overall image quality.

Now that we know how the Panasonic Z85A handles tonal transitions in 4K materials, it's time to look at its "Gradation Smoothing" feature. It works, but unfortunately not entirely effectively. Regardless of the selected value – whether low, medium, or high – we were unable to achieve perfectly smooth tonal transitions in our test sequence. We recommend setting this feature to an intermediate level. While it may slightly blur fine details, it at least avoids the problem of losing film grain, which can be crucial for many viewers when watching classic productions.

When it comes to image scaling, the television performs quite well. It is evident that the image is slightly sharpened, and thin lines can sometimes appear somewhat jagged. However, this is standard in most televisions and fortunately, it can be adjusted using the sharpness slider. This gives us full control – we can achieve a more plastic, blurred image or a clearer one, though more "harsh" and artificially sharp. It all depends on the user’s preferences and the type of content we are watching. Overall, the scaling is at a solid level and should satisfy most users who are using lower resolution materials.

This paragraph will be notably brief due to the absence of even basic motion-smoothing functionality, which is unsurprising given the device's budget-oriented nature. The VA panel used here is not known for exceptional sharpness and is instead associated with high contrast and slower response times, as confirmed by the matrix analysis results. Photos captured during fast motion reveal typical motion blur for this type of panel. While not ideal, the television could be conditionally suitable for watching sports, though viewers should expect less-than-optimal motion clarity. Additionally, films may exhibit noticeable stuttering due to the lack of any motion-smoothing features, even basic ones.

The Panasonic Z85A has a 120 Hz panel, which will surely please both gamers and sports fans. Sure, it's not 144 Hz like some gaming TVs, but in practice, the difference is really hard to notice. In games, the image is stable and clear, and during fast action, there's no sign of any motion blur. The same goes for sports – a quick run by a soccer player or a dynamic car maneuver looks smooth and natural. The TV also has an "Intelligent Frame Creation" feature, which is a motion smoother. There are two sliders – one for reducing motion blur and the other for motion smoothness. With these, you can adjust the picture to your personal preferences – whether you prefer a more cinematic effect with gentle transitions between frames or a maximally smooth image perfect for watching sports.

The Philips PUS8079 provides only basic gaming features, including ALLM, VRR, and a Game Bar. The key highlight is the inclusion of dynamic frequency adjustment, which ensures a smooth image with minimal screen tearing—an impressive offering for this price range.

A notable benefit for gamers is the presence of the Game Bar, allowing adjustments to be made "on the fly" without needing to exit the game. Importantly, this feature retains options found in higher-end models, such as shadow enhancement for improved visibility in darker areas and a colour filter designed to assist gamers with visual impairments.

Panasonic is mainly associated with home cinema televisions, but the Z85A shows that it can also enter the gaming world with a really strong punch. This is equipment that can easily be called a gaming beast - it has everything needed for comfortable gameplay.

Even though we only have two HDMI 2.1 ports, both operate at full bandwidth, so we can easily connect both a next-gen console and a gaming PC. All key features are supported: ALLM automatically switches the TV to game mode, VRR ensures smooth images without stuttering and tearing, and with properly implemented HGIG and Dolby Vision, HDR games look really good - colors are vivid, details clear, and dark scenes readable. There is also a Game Bar in the form of a clear, circular menu. It may not look as impressive as with the competition, but it is intuitive and contains all the most important settings that we would like to have at hand during gaming.

In summary - the Panasonic Z85A is equipment that really surprises with its gaming capabilities. It is a television where both console gamers and PC gamers will feel at home. It's smooth, dynamic, and simply good.
