Samsung DU8002 (IPS) vs Panasonic Z85A

The HDR effect on the DU8002 television leaves much to be desired. A brightness level of 300 nits cannot provide a true high dynamic range experience, which makes the viewed content resemble more of a standard SDR than impressive HDR. Scenes that should dazzle with brilliance and detail appear muted and lacking in depth. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 colour gamut at 92%. This means that colours are vivid and saturated, which may satisfy viewers who prefer rich tones, even if the HDR effect does not fully meet expectations.

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 DU8002 offers a Filmmaker mode, which is intended to provide an authentic image reproduction in line with the creators' vision. Unfortunately, despite the promising name, the results are far from ideal. The white balance in this mode shows significant drops in blue, leading to a noticeable yellowing of the image, as seen in our comparison photo. Colour Checker tests confirm these errors. As for brightness, the gamma characteristic is too low compared to the reference line of 2.4, resulting in excessive screen brightness. A similar issue occurs with 4K content – the EOTF responsible for brightness in 4K material shows significant increases above the reference line, leading to excessively bright small light elements. As a result, the Filmmaker mode in the DU8002 does not meet expectations and instead of offering high quality, presents an image full of tonal and colour inaccuracies.

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 is one of those companies that offers advanced tools for improving picture quality in its televisions, including a 20-point white balance adjustment. Even in the budget model DU8002, with the right adjustments, surprisingly good results can be achieved. The white balance, especially for HD content, is really good – tests on the Colour Checker palette confirm accuracy levels of 2–1.5, which speaks to this television's considerable capabilities in colour reproduction. In 4K content, although not as perfect as in lower quality materials, the overall picture looks significantly better.

The gamma brightness has also been heavily adjusted, meaning the picture is not overly bright and looks more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it is clear that the television, due to its low contrast matrix, struggles. The EOTF also drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where calibration is worth investing in. Although construction flaws, such as the type of backlighting, cannot be completely eliminated, colour accuracy is surprisingly good, especially given its price.

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.

Smoothing tonal transitions on the DU8002 television leaves a mixed impression. Although the menu features an option for smoothing tonal transitions, in practice it yields no results and may even generate unwanted side effects.

Nevertheless, the television performs excellently with upscaling, or digital image processing. The test pattern with the model looked really good – the image is not excessively jagged, and the overall presentation is decent and pleasant to the eye. This is definitely good news for those planning to watch traditional television on this model.

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 DU8002 with a 60 Hz panel is a television that performs better for watching films than for intense gaming. The motion smoothing feature acts as a fluidizer, smoothing out movement and giving scenes a more fluid appearance, which is helpful for movie screenings. In the context of gaming, this model is more suited for casual entertainment.

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.

DU8002 is a television that is primarily suitable for casual gamers. The 60 Hz panel does not provide the highest motion smoothness, so in dynamic games, there may be a lack of that extra fluidity in the picture. On the plus side, it features ALLM and HGiG functions, which automatically adjust the picture settings for HDR gaming, enhancing the gaming experience. Unfortunately, the television is equipped only with HDMI 2.0 ports, so we will have to forget about more advanced features like VRR or support for 4K at 120 Hz. With this equipment, we will have to settle for less if we expect a full set of gaming features.

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.
