Philips OLED909 vs Panasonic Z85A

Philips OLED909 impresses with its HDR quality, achieving up to 1500 nits of peak brightness in tested scenes. This is an excellent result, placing this television among the best OLED models on the market. The MLA panel, also used in models such as the Panasonic Z95A and LG G4, plays a key role here, allowing for exceptionally bright and detailed reproduction of dynamic scenes. However, it is worth noting that in the most demanding scene from the film The Meg, brightness drops to around 700 nits. This is a typical phenomenon in OLED technology, where intensely bright full-screen images cause a limitation in luminance. Nevertheless, the HDR effect still looks very good, and the television performs better than most of the competition under similar conditions. The wide colour gamut coverage also deserves praise. The OLED909 offers 95% coverage of DCI-P3, ensuring that the television can display vibrant and realistic colours.

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.

Just like with other televisions, the Philips OLED909 has been tested for colour reproduction in factory modes. The best mode turned out to be Filmmaker Mode, however, despite its name, it is not without flaws.

The biggest problem is the white balance. In both HD and 4K HDR content, there is a noticeable dominance of green and red hues, which causes a distinct yellowing of the screen. This effect is particularly evident in test materials, for instance in a scene with Tom Cruise in the foreground, where the difference compared to a calibrated image is very apparent.

As for brightness characteristics, in HD material the gamma was overly boosted – it was below the reference value of 2.4, which gave the image a “milky” filter and affected overall clarity. In the case of 4K HDR content, we noticed the opposite phenomenon – at the beginning of the EOTF curve, there is a noticeable drop, indicating problems with reproducing the smallest details in dark scenes. Although Filmmaker Mode offers acceptable quality, noticeable errors in white balance and brightness characteristics show that the television requires additional calibration to fully demonstrate its potential in colour reproduction.

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!

Philips OLED909 offers tools for image calibration, which significantly improves its quality. After calibrating the Filmmaker Mode, the television presents a much more natural colour representation. The white balance after calibration looks very good. Although we noticed slight deviations in the blue tint in HD content, the errors are within acceptable limits, and the image gives a much better impression than in the factory settings. The brightness characteristics, including gamma and EOTF, have also been clearly improved. The television no longer has issues with excessive brightening or darkening of the image. Both dark and bright details are now rendered correctly, making the image look very good in every scene. After calibration, the Filmmaker Mode in the Philips OLED909 offers excellent image quality that will meet the expectations of even the more demanding users. Calibration fully utilises the potential of this model.

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.

The Philips OLED909 offers a distortion reduction feature aimed at smoothing tonal transitions. Unfortunately, the effectiveness of this function leaves much to be desired. Setting it to the "Medium" level brings certain effects, but it comes with the risk of blurring important details in the image. For this reason, we do not recommend using this option unless we are keen on mitigating visible artifacts at the cost of detail.

As for image scaling, the television presents a very plastic image, which may appeal to viewers who prefer a softer picture. Those expecting clearer sharpness will also find a solution, as image scaling can be adjusted according to individual preferences in the settings.

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 Philips OLED909 with a 144 Hz panel offers excellent motion smoothness, which should satisfy both film enthusiasts and gamers. Additionally, the television is equipped with a motion smoothing feature called "Motion Style", which allows for precise adjustment of motion fluidity to personal preferences. In the settings, we find two sliders: "Smoothness", responsible for regulating motion fluidity in films, and "Blur Reduction", which helps eliminate minor artifacts and distortions in dynamic scenes. This feature works well, ensuring that even rapid movements on the screen are clear and readable.

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.

The Philips OLED909 is a television that meets practically all the requirements of gamers. Equipped with ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and support for Dolby Vision, it guarantees an excellent gaming experience. Additionally, the television offers very low input lag, ensuring that reactions to player movements are instantaneous, which will be particularly appreciated by fans of fast-paced games.

The television handles any resolution at 120 Hz without any issues, and even supports higher refresh rates. The HGiG feature, responsible for accurately displaying HDR content in games, works as it should, making the image in game mode balanced and aligned with the guidelines of console manufacturers.

The OLED909 is also equipped with the Game Bar feature, which allows for quick preview and adjustment of game-related settings. Although the interface of this solution appears less visually appealing than that of competitors, it serves its purpose well, offering all the essential options in one place.

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.
