Panasonic Z85A vs Samsung S85F OLED

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.

As an OLED, the Samsung S85F can shine – literally. In favourable conditions, it can generate brightness exceeding 750 nits. This is significant because most films are created with displays aiming for around 1000 nits. In practice, this means that in scenes with moderately large, bright elements, the picture can look absolutely stunning. However, it's not always so rosy. When an enormous amount of light appears on the screen – whether it's an expansive, bright background or an entire frame filled with white – the S85F must tone it down. Brightness can drop by even four times in such scenes. This limitation is well-known to anyone familiar with OLEDs in this price segment, so we don't view it as a particular fail. However, something that deserves praise is what sets this model apart from the competition – colour gamut coverage. Thanks to the QD-OLED panel, our colour meter indicated values exceeding 100% coverage of DCI-P3 and an impressive 86% for the ultra-wide BT.2020 palette. Such results are hard to find even in televisions that cost several times more.

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!

Samsung, as befits a manufacturer with ambitions, has equipped the S85F with a mode called Filmmaker. Its task is simple: to make the colours on the newly purchased television as faithful as possible to what the director intended to show us. Sounds great… but, as is often the case, a theory that sounds wonderful doesn’t 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 if someone had gone a bit overboard with the saturation. As a result, there were quite significant colour errors, particularly in 4K content. On top of that, there was an issue with brightness – the S85F could brighten most scenes more than it should, stripping them of the intended mood.

Fortunately, Samsung televisions, including the S85F, offer an impressive number of settings for advanced calibrators. This means that we could see what this panel is really capable of when it gets into the right hands.

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.

Thanks to the huge number of settings in the menu, we managed to bring the S85F almost to perfection. White balance in SDR content? Literally perfect – deviations do not exceed a value of "1". So we can confidently say that in materials with not too high dynamics, we have an image that's close to reference.

In HDR content, minor issues appeared, but they don't have much significance in practice – most errors fall below the threshold of perception, which is a value of "3". We also managed to tame the S85F when it comes to brightness management – the EOTF curve, even in films, holds nearly perfect straight line. This is one of those cases where after calibration, you can comfortably forget about the settings and simply watch movies and series at the highest level.

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 tone transition smoothing function in the S85F works really effectively – it can completely eliminate the problem of visible banding in very poor quality material, such as from YouTube. Unfortunately, even the lowest level of this option comes with compromises. The noise reduction is so aggressive that it can smooth out film grain, which many of us consider to be an element of the cinematic atmosphere. At the “Standard” level, we didn’t notice this function removing 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 just noise, but also small, desirable details like, for example, the texture of objects.

When it comes to image scaling, the S85F performs very well. The material looks sharp, and the only slight imperfection is the barely noticeable aliasing of edges. And there’s the ongoing issue with Samsung televisions – overscan. This can cause some scenes to be slightly cropped, which is worth noting when watching very old content.

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.

S85F is an incredibly fast television – and that’s not just empty hype. Thanks to the 120 Hz OLED panel, dynamic scenes, whether in games or while watching a live match, look just as they should – smooth, sharp, and without the feeling that something is "slipping" out of frame. The lightning-fast pixel response time, typical of OLEDs, plays a big role here. Transitions between frames are virtually instantaneous, and the image remains clear even during the fastest camera movements. A ball flying across half the field? A car speeding in a chase scene? Everything here is clear and free of the typical "trail" associated with LCDs.

This is exactly what we expect from a good OLED – zero compromises when it comes to motion smoothness. The S85F gives the impression that regardless of the pace of action, we can focus on what’s happening on the screen, rather than on the imperfections of the image.

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.

[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.

S85F has practically everything on board to become the dream screen for gaming. Four full 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 – plus a gem in the form of Game Motion Plus. This motion smoother makes animation in games more enjoyable, while input lag increases slightly. It's a rare combination, and that’s a big plus for Samsung. Perhaps Samsung will fix this in the next update – and we have high hopes for that. Because if HGiG comes back, the S85F will become nearly the perfect TV for gamers.
