Panasonic Z85A vs Philips OLED910

The Panasonic Z85A is an OLED television, so you can immediately expect excellent effects in films. And indeed – our tests showed that the WOLED panel can achieve around 800 nits of peak brightness in optimal conditions. This is a solid result, performing well in most demanding HDR scenes, allowing viewers to enjoy a dynamic and detailed picture. However, like every OLED, the Z85A also has its limits. In very bright scenes that fill the entire screen – like the final sequence from the movie The Meg – the television reduces brightness to around 400 nits. This is standard behaviour for this technology, so if someone plans to watch films in a heavily sunlit living room, it is worth keeping this in mind. The coverage of the DCI-P3 colour gamut at 98% also deserves high praise. This allows the television to reproduce a wide range of colours that stand out with vibrancy and depth, while details in HDR scenes are sharp and precise. In short – the Panasonic Z85A delivers a solid HDR effect that will satisfy any film enthusiast.

OLED910 is simply an absurdly bright television for an OLED. All thanks to the new panel from LG Display, the Tandem RGB OLED, which Philips has branded as "META OLED". It is this panel that allows for over 2000 nits of brightness in films, which not long ago was completely unachievable in OLEDs. The way the television handles full-screen scenes flooded with bright light also deserves high praise. Usually, in OLEDs, brightness drops significantly, but here it remains at a great level – around 1400 nits. These values are almost reference-level, and combined with excellent colour reproduction at 99% DCI P3 and 82% BT.2020, it gives us an HDR effect that can confidently be called one of the best in the world.

The Panasonic Z85A offers many picture modes, but the Filmmaker mode definitely stands out from the rest. It's rare for a TV straight out of the box to be so well calibrated, and the unit we had the opportunity to test truly impressed us.

However, there were some minor shortcomings. In the SDR signal, we noticed a slight deficit of red and blue, which made the picture appear cooler than it should have been. This is particularly evident in the comparison image. In contrast, with 4K HDR material, the situation was the opposite – the surplus of red made the image seem warmer than intended by the creators. In terms of brightness characteristics (gamma) and maintaining an appropriate EOTF curve, it's hard to find faults. There are slight deviations, but they are so minimal that the average viewer is unlikely to notice them.

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

Unfortunately, when it comes to colour reproduction straight out of the box, the Filmmaker mode on the OLED910 really falls short. The television overemphasises the blue colour and at times it looks almost like a shop mode. It gives the impression that the manufacturer hasn't quite calibrated the device properly. The result is that colours appear unnatural, and the overall look resembles a slightly exaggerated display from a store showcase. HDR content looks much better, where apart from a slight loss of detail in blacks, there’s hardly anything to complain about. The problem is that in everyday viewing, it’s actually SDR materials that matter the most – and on the OLED910, they just look poor and significantly deviate from what we would expect from a television of this class.

The Panasonic Z85A offers truly wide-ranging capabilities when it comes to picture settings, so we eagerly set about calibrating it. Although we mainly focused on adjusting the white balance, the final effect exceeded our expectations. Both HD and 4K HDR content now showcases nearly perfect colour reproduction, with minimal errors that are hard to catch with the naked eye. Well-calibrated TVs are a rarity, and we must admit – it’s truly satisfying. While the gamma and EOTF curve didn't require drastic adjustments, we managed to further stabilise their characteristics across the entire brightness scale. After calibration, the Panasonic Z85A is a true gem for home cinema enthusiasts. The picture is precise, the colours are natural, and every scene looks exactly as the director intended.

Fortunately, it quickly turned out that it wasn't the panel causing the problems, but the way Philips factory-tuned the OLED910. After calibration, the television showcased its full potential, and only then could we see what the new panels from LG Display were truly capable of. We primarily corrected the white balance and brightness characteristics, successfully taming the excessive blue and giving the image a natural look. The final effect can be described as excellent. Errors on the Color Checker palette rarely exceeded a value of 3, which in practice means an image close to ideal and colours presented in line with the creators' intent. In SDR content, the effect was stunning, and in HDR, the improvement was even more noticeable – gradients became cleaner, and colours fuller and more accurate. After calibration, the OLED910 transformed from a disappointing television into equipment that can be confidently referred to as reference-grade in terms of colour accuracy.

Now that we know how the Panasonic Z85A handles tonal transitions in 4K material, it’s time to take a look at its "Gradation Smoothing" function. It works, but unfortunately not entirely effectively. Regardless of the chosen value – whether it’s low, medium, or high level – we couldn’t achieve perfectly smooth tonal transitions in our test sequence. We recommend setting this function to an intermediate level. While this may slightly blur fine details, at least it 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 TV performs quite well. It’s noticeable that the image is slightly sharpened, and thin lines can sometimes appear a bit jagged. However, this is standard for most TVs, and fortunately, it can be adjusted using the sharpness slider. This gives us full control – we can achieve a more vivid, blurred image or a clearer one, although it may appear more "harsh" and artificially sharp. It all depends on the user's preferences and the type of content we’re watching. Overall, the scaling is at a solid level and should satisfy most users who are using lower resolution material.

The previously visible colour connections can be largely mitigated thanks to a feature called "distortion reduction." Similar to the OLED820, it’s best to set it to medium level, as it then provides quite decent results – smoothing unwanted tonal transitions while not taking away too many details from the image. Although at times the effect may be a bit too aggressive, in everyday viewing, this function can be considered useful.

When it comes to image scaling, the OLED910 performs really well. The test material with the model showcased a characteristic soft look typical of Philips – at times almost too soft – but at any moment this can be adjusted with the sharpness slider to tailor the image to your own preferences. It’s also a plus that the television has no issues with overscan, which still occurs in some competitors' models. It’s a minor detail, but it’s pleasing as it means that all content, even the oldest, is displayed as it should be.

The Panasonic Z85A features 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 picture is stable and sharp, and during fast action, there’s no sign of any blurring. The same goes for sports – a player’s quick run or a car’s dynamic maneuver looks smooth and natural. The TV also has an “Intelligent Frame Creation” feature, which is a motion smoother. There are two sliders here – one controls motion blur reduction, while the other adjusts motion smoothness. With these, you can tailor the picture to your own preferences – whether you prefer a more cinematic effect with gentle transitions between frames or a maximally smooth image ideal for watching sport.

OLED910 is a TV with a refresh rate of 144 Hz. It’s a bit of a shame that Philips didn’t opt for 165 Hz, as we know that the matrix used in it is capable of that. On the other hand, such a bonus will mainly benefit PC gamers, as for everyday use, the most important thing is the 120 Hz refresh rate, which is fully sufficient. Combined with the advantages of the OLED matrix – lightning-fast pixel response times and the absence of motion blur, the picture is impeccably sharp and fast, even in dynamic action scenes. The traditional motion smoother from Philips called “Motion Style” also deserves praise. We can easily adjust it to our own preferences: the “Smoothness” slider is for movies and allows you to choose between a more “framey,” cinematic character and a smooth, theatrical image. Meanwhile, the “Motion Blur Reduction” slider is intended for sports; here, it’s worth setting it to the maximum value so that the image is clear and sharp during very fast shots.

Panasonic is mainly associated with home cinema televisions, but the Z85A shows that it can also step into the gaming world with a truly strong punch. It's a device that can easily be called a gaming beast – it has everything needed for comfortable gameplay.

Even though it has only 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 the key features are supported: ALLM automatically switches the television into game mode, VRR provides smooth visuals without stuttering and tearing, and with properly implemented HGIG and Dolby Vision, HDR games look really good – colours are vivid, details are sharp, and dark scenes are clear. We also find a Game Bar in the form of a transparent, circular menu. It may not look as impressive as the competition's, but it's intuitive and includes all the most important settings we’d want at hand during gameplay.

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

The OLED910 is fantastic for gaming. It supports 144 Hz, so if someone has a powerful PC, they'll easily make the most of that potential. For consoles, the most important thing is still 120 Hz, and everything works smoothly here. It has VRR, an automatic game mode, and even Dolby Vision in games along with HGiG mode, so we pretty much get a full package of gaming features. Philips also added a Game Bar, which is like a quick menu that shows basic information and allows you to enable a few handy features. It might not look as modern as the competition, but it works and does its job. The only downside is the number of HDMI 2.1 ports. There are only two, which can be quite disappointing in this class of television. If someone connects two consoles and something extra to the eARC - like a soundbar (which doesn't really make sense in this model, but more on that in the sound section), they'll have to do a bit more figuring around. Other than that, though, the OLED910 has everything we expect from a gaming TV.
