Samsung Neo QLED QN85D / QNX1D vs Panasonic Z85A

Samsung QN85D leaves us with mixed feelings regarding HDR quality. It can shine in synthetic luminance tests, reaching even 1000 nits – which makes scenes like those from 'The Meg' or the start of 'Life of Pi', where the screen is all bright, look truly impressive. However, in practice, the device has its limitations – especially when smaller bright elements appear on the screen. In such moments, brightness noticeably drops, and the HDR effect loses its punch. At brightness levels around 200-300 nits, the magic of HDR simply fades away, not delivering spectacular effects. However, it’s not that the television completely disappoints – coverage of the DCI-P3 colour gamut at 95% is quite decent, although it doesn’t stand out against the best competitors. Colours are well-rendered, but it's clear that HDR could make a bigger impression if brightness could be better controlled.

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.

Samsung QN85D TV has been tested in the best available mode – Filmmaker. While one might expect its name suggests a mode perfectly suited for films, unfortunately, it has several significant issues.

When it comes to white balance for HD content, there is a noticeable dominance of red and blue, which makes the entire image take on pinkish hues – this is also confirmed by Colour Checker tests. This effect disturbs the naturalness of skin tones and many other elements, which is particularly evident in more demanding scenes. Initially, the white balance for 4K HDR content seems correct, but at the end of the graph, there is a significant spike in blue hues, affecting the final image quality and making the colours appear unnatural.

The gamma brightness characteristic is also not ideal – although it generally stays close to the reference value, there is a slight drop below 2.4, which can impact the perceived depth of shadows. The EOTF curve responsible for 4K content does not perform any better. There is a clear boost compared to the reference curve, leading to excessive brightness in some areas, thus losing the cinematic quality that the Filmmaker mode should provide. While it might initially seem that the effect is cinematic, unfortunately, the number of errors in colour and brightness reproduction is too significant to call it flawless.

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!

After professional calibration of the Filmmaker mode on the Samsung QN85D television, a significant improvement is noticeable, especially for HD/SDR content. The white balance has been completely free of major errors, and the brightness characteristics for this type of content have been significantly adjusted, allowing for a more natural and realistic image. Television, YouTube films, and other HD materials now look much better, with appropriately balanced colours and without the exaggerated hues that previously marred the experience.

However, the biggest issues arise with 4K HDR content. Despite the calibration, it's hard to speak of significant improvement in white balance here – the differences are cosmetic rather than essential. Brightness, governed by the EOTF curve, seems to be set according to the reference level in synthetic tests at first glance, but has its limitations during actual viewing in films. When analysing the EOTF curve in real film scenes, it becomes clear that the television struggles to maintain consistency in brightness. The effect is that mixed scenes still have their darkest elements boosted, leading to exaggerated contrasts, and completely dark scenes remain too dark, which negatively affects the visibility of details.

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.

When checking the fluidity of tonal transitions in low-resolution materials on the Samsung QN85D television, it’s worth noting the noise reduction feature, which significantly improves problematic tonal transitions. On the other hand, this feature also has its downsides – it removes film grain, which is an important element of many productions, giving them authenticity, and it can also soften the image. This may appeal to those who prefer a smoother picture; however, for lovers of the authentic look of films, using this feature should be considered carefully.

Regarding image scaling, the television performs very well. The model's figure is presented correctly, without noticeable distortions, and the branches in the background do not have excessive artificial sharpness, which is often a problem when scaling lower resolution materials. The high capabilities of the image processor are evident here, which can effectively process lower quality materials, ensuring good final quality.

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.

Samsung QN85D TV is equipped with a 120 Hz refresh rate panel, which should satisfy both gamers and sports enthusiasts by offering a smooth and dynamic image. There are options to enhance fluidity, such as the blur and judder reduction feature, which allows precise motion fluidity adjustments on a 10-point scale. The blur reduction increases the sharpness of fast-moving objects, making action scenes more readable, while judder reduction smooths out motion, eliminating the “judder” effect. Ghosting is generally well controlled, though minor imperfections can be visible in more demanding scenes, especially when an object moves against a dark background. Additionally, the TV offers a BFI (Black Frame Insertion) feature at a 60 Hz refresh rate, which can significantly improve motion fluidity experience, although at the cost of image flicker, which might be bothersome for some users.

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.

The Samsung QN85D television is an excellent choice for gamers, offering a wide range of features that enhance the gaming experience and make it even more exciting. With a 120 Hz refresh rate panel, the image is incredibly smooth, which is crucial during dynamic scenes in action games. The television also boasts low input lag, allowing for nearly instant reactions to player commands, which translates into better control over characters and events on the screen.

In addition, the QN85D Samsung supports VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) technologies, which optimise image smoothness and reduce delays by automatically adjusting the television to the needs of gamers. Moreover, the Xbox app allows for cloud gaming without the need for a console, which is a big plus for those who want to enjoy their favourite titles without additional hardware – a feature that sets Samsung televisions apart.

The Auto Motion Plus Game feature is another aspect worth highlighting. This motion smoothing technology creates the illusion of more frames per second – as a result, games at 30 fps appear smoother, resembling gameplay at 45 fps, while games at 60 Hz come closer to 90 Hz. Most importantly, this feature does not introduce significant lag, ensuring that gaming comfort is not compromised. This allows gamers to enjoy a smoother image without compromising responsiveness.

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.
