Panasonic Z85A vs Samsung S85F OLED

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.

For an OLED, the Samsung S85F can truly shine – literally. Under favourable conditions, it is capable of generating brightness exceeding 750 nits. This is hugely significant, as most films are created with displays reaching around 1000 nits in mind. In practice, this means that in scenes with moderately large, bright elements, the image can look simply fantastic. However, it's not always so rosy. When there is a huge amount of light on the screen – whether it's an expansive, bright background or a whole frame filled with white – the S85F has to tone it down. In such scenes, brightness can drop by even four times. This limitation is well-known to essentially every OLED in this price segment, so we do not consider it a particular shortcoming. However, something that deserves praise and sets this model apart from the competition is its colour gamut coverage. Thanks to the QD-OLED panel, our colourimeter recorded values exceeding 100% DCI-P3 coverage and as much as 86% for the ultra-wide BT.2020 gamut. Such results are hard to find even in televisions costing several times more.

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!

Samsung, as befits a manufacturer with ambitions, has equipped the S85F with a mode called Filmmaker. Its task is simple: to ensure that the colours on the newly purchased television are as true to what the director intended as possible. Sounds great… but, as is often the case, a theory that sounds great does not always translate into perfect practice.

In the tested unit, it quickly became apparent that the image – due to an excess of blue and red – looked as though someone had overdone the saturation a bit. As a result, quite significant colour errors occurred, particularly in 4K content. Moreover, there was a problem with brightness – the S85F could brighten most scenes more than it should, taking away their intended mood.

Fortunately, Samsung televisions, including the S85F, offer an impressive number of settings for advanced calibrators. This means that we could test what this panel is truly capable of when placed in the right hands.

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.

Thanks to the vast number of settings in the menu, we managed to bring the S85F to nearly an ideal level. The white balance in SDR content? Literally perfect – deviations do not exceed the value of “1”. So we can confidently say that in materials with not very high dynamics, we have an image close to reference here.

In HDR content, slight issues have arisen, but they are not significant in practice – most errors fall below the threshold of perceptibility, which is the value of “3”. We also managed to tame the S85F when it comes to brightness management – the EOTF curve, even in movies, holds an almost perfect line. This is one of those cases where after calibration, you can comfortably forget about the settings and simply enjoy films and series at the highest level.

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 tonal transition smoothing function in the S85F works really effectively – it can completely eliminate the problem of visible banding in very poor quality materials, such as those from YouTube. Unfortunately, even the lowest level of this option comes with compromises. Noise reduction is aggressive enough that it can smooth out the film grain that many of us consider a key element of the cinematic experience. At the "Standard" level, we did not notice that this function removed anything significant from the image, so we can recommend this setting. On the other hand, the "High" level is a different story – it can smooth out not only noise but also subtle, desirable details such as the texture of objects.

As for image scaling, the S85F performs very well. The material looks sharp, and the only minor imperfection is slightly visible aliasing of contours. And there’s still the persistent issue with Samsung televisions – overscan. This can cause the frame to be slightly cropped in certain scenes, which is worth keeping in mind when watching very old content.

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 S85F is a mind-blowingly fast television – and this is not just an empty phrase for effect. Thanks to the 120 Hz OLED panel, dynamic scenes, whether in games or while watching a live match, look exactly as they should – smoothly, sharply, and without the feeling that something is “slipping away” from the frame. The lightning-fast pixel response time, typical of OLEDs, plays its part here. Transitions between frames are virtually instantaneous, and the picture remains clear even during the fastest camera movements. A ball flying across half the pitch? A car racing in a chase scene? Here, everything is clear and free from the characteristic “trail” of LCDs.

This is exactly what we expect from a good OLED – no compromises when it comes to motion fluidity. The S85F gives the impression that regardless of the pace of the action, we can focus on what is happening on the screen, rather than the imperfections of the image.

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.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.

The S85F has practically everything on board to become the dream screen for gaming. Four full-fledged HDMI 2.1 ports with a bandwidth of 48 Gb/s, support for VRR, ALLM, a super-detailed Game Bar that clearly shows all parameters – and on top of that, a gem in the form of Game Motion Plus. This motion smoother makes animation in games more enjoyable, while input lag only increases slightly. This is a rare combination, and it’s a big plus for Samsung. Now comes the moment when we need to complain a little. The lack of Dolby Vision in Samsung televisions has become standard, so there’s no point in hoping (unless something changes in a few years) – but the disappearance of HGiG after the software update is something hard to explain. HGiG (which stands for HDR Gaming Interest Group) is a mode that allows for precise reproduction of brightness in HDR games, in accordance with the creators' intentions. Without it, HDR calibration on a console becomes less precise, so we can end up with an image that is too dark in the shadows or excessively overexposed. Perhaps Samsung will fix this in the next update – and we have high hopes for that. Because if HGiG returns, the S85F will become nearly the perfect television for gamers.
