Panasonic Z85A vs Philips OLED910

The Panasonic Z85A is an OLED television, so one can immediately expect great effects in films. And indeed – our tests have shown 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 viewers to enjoy a dynamic and detail-rich image. However, like any OLED, the Z85A has its limits. In very bright scenes covering the entire screen – such as the final sequence from the film 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 brightly sunlit living room, it is worth keeping this in mind. The coverage of the DCI-P3 colour gamut at 98% also deserves high praise. Thanks to this, the television reproduces a wide range of colours that stand out with vibrancy and depth, and details in HDR scenes are sharp and precise. In short – the Panasonic Z85A delivers a solid HDR effect that will satisfy any film enthusiast.

The 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 dubbed its "META OLED." It is this panel that allows for over 2000 nits of brightness in films, which not long ago was completely unattainable in OLEDs. The television also deserves high praise for how it handles full-screen scenes drenched in bright light. Generally, in OLEDs, brightness drops significantly during such scenes, but here it remains at an excellent level – around 1400 nits. These are almost reference values, and combined with the 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 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 surprised us positively.

However, there were a few minor shortcomings. In the SDR signal, we noticed a slight deficit of red and blue, which resulted in the image having a cooler hue than it should have. This is especially noticeable in the comparative photo. Conversely, in 4K HDR content, the situation was the opposite – an excess of red made the image appear warmer than the creators intended. In terms of brightness characteristics (gamma) and the maintenance of the appropriate EOTF curve, it's hard to find fault. There are slight deviations, but they are so minimal that the average viewer is unlikely to notice them.

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

Unfortunately, when it comes to colour reproduction straight out of the box, the Filmmaker mode on the OLED910 performs really poorly. The television overemphasises the blue colour, and at times it looks almost like a shop display mode. This gives the impression that the manufacturer hasn’t quite tuned the device properly. The effect is that the colours look unnatural, and the whole thing resembles a somewhat exaggerated display from a market exhibition. HDR content is presented much better, where, apart from a slight loss of detail in the blacks, there’s not much to complain about. The problem is that in everyday viewing, it’s the SDR materials that matter the most – and on the OLED910, they simply look poor and fall well short of what we would expect from a television of this class.

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

Fortunately, it quickly turned out that it was not the panel causing the problems, but rather the way Philips factory-calibrated the OLED910. After calibration, the television displayed its full potential, and only then could we see what the new panels produced by LG Display were truly capable of. We primarily adjusted the white balance and brightness characteristics, successfully taming the excessive blue and giving the image a natural appearance. 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 perfection and colours presented in accordance with the creators' intent. In SDR content, the effect was outstanding, 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 confidently be referred to as a reference in terms of colour quality.

Now that we know how the Panasonic Z85A performs with tonal transitions in 4K content, it’s time to take a look at its "Gradation Smoothing" feature. It works, but unfortunately not entirely effectively. Regardless of the chosen value – whether it’s 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. Although it may slightly blur fine details, at least the issue of film grain loss does not occur, which for many viewers can be crucial when watching classic productions.

As for image scaling, the television performs quite well. It’s noticeable that the image is slightly sharpened, and slim lines may at times appear a bit jagged. However, this is standard in most TVs, and fortunately, it can be adjusted using the sharpness slider. This gives us complete control – we can achieve a more plastic, blurred image or a clearer one, although it may be more “harsh” and artificially sharp. It all depends on user preference 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.

The previously visible colour banding can largely be mitigated thanks to a feature called "distortion reduction." Like in the OLED820, it is best set to a medium level, as it then produces fairly decent results – smoothing out unwanted tonal transitions while not taking away too much detail from the image. Although at times the effect may be slightly too aggressive, this function can be considered useful for everyday viewing.

As for image scaling, the OLED910 performs really well. The test material featuring a model had a soft look characteristic of Philips – at times almost too soft – but this can be easily corrected with the sharpness slider, allowing you to adjust the image to your own preferences. It's also worth noting that the television has no issues with overscan, which still occurs in some competitor models. It's a small detail, but it's pleasing because it means that all content, even the oldest, is displayed as it should be.

The Panasonic Z85A features a 120 Hz panel, which will certainly please both gamers and sports fans. Admittedly, it is 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 is no sign of any blurring. The same applies to sports – a fast-running footballer or a dynamic car manoeuvre looks smooth and natural. The TV also has the “Intelligent Frame Creation” function, which is a motion smoother. There are two sliders here – one is for reducing blur, and the other is for motion smoothness. With these, you can adjust the image to your own preferences – whether it be more of a cinematic effect with gentle transitions between frames, or a maximally smooth image ideal for watching sports.

OLED910 is a television 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 panel used is capable of that. On the other hand, such a bonus would mainly benefit PC gamers, as in everyday use, the most important refresh rate is 120 Hz, which is fully sufficient. Combined with the advantages of the OLED panel – lightning-fast pixel response time and the absence of motion blur, the image is impeccably sharp and quick, even in dynamic action scenes. The traditional motion smoother from Philips, called “Motion Style,” also deserves praise. We can easily adjust it to our preferences: the “Fluidity” slider is responsible for films and allows you to choose between a more “filmy,” cinematic character and a smooth, theatrical image. Meanwhile, the “Motion Blur Reduction” slider is intended for sports, where it’s worth setting it to the maximum value to ensure that the image is clear and distinct during very fast shots.

Panasonic is mainly associated with home cinema televisions, but the Z85A demonstrates that it can also step into the gaming world with a really strong impact. This hardware can easily be called a gaming beast – it has everything needed for comfortable gameplay.

Although there are 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 key features are supported: ALLM automatically switches the television to game mode, VRR ensures smooth images without stuttering or tearing, and with correctly 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 clear, circular menu. It may not look as impressive as the competition's, but it is intuitive and contains all the important settings we would like to have at hand during gameplay.

In summary – the Panasonic Z85A is equipment that truly surprises with its gaming capabilities. It is a television on which both console gamers and PC players will feel at home. It is smooth, dynamic, and simply good.

The OLED910 is fantastic for gaming. It supports 144 Hz, so if someone has a powerful PC, they can comfortably utilise that potential. On consoles, the most important thing is still 120 Hz, and everything works perfectly here. There's VRR, an automatic gaming mode, and even Dolby Vision in games and HGiG mode, so we really get a full package of gaming features. Philips has also added a Game Bar, which is a quick menu that displays basic information and allows you to enable a few useful things. It may not look as modern as the competition, but it works and fulfils its purpose. The only downside is the number of HDMI 2.1 ports. There are only two, which can be quite disappointing for a TV in this class. If someone connects two consoles and something additional through eARC - like a soundbar (which doesn't make much sense in this model but I'll discuss that in the paragraph about sound) - they'll have to do some adjustments. Other than that, the OLED910 has everything we expect from a gaming television.
