Samsung DU7192 (IPS) vs Panasonic Z95A

The maximum luminance in HDR materials is 245 nits, which is often surpassed by even lower results. Such values will definitely not be sufficient for comfortable viewing of HDR materials due to the lack of appropriate image dynamics and colour inaccuracies caused by the low brightness of the unit. Although the manufacturer has equipped its device with HDR format offering dynamic metadata, HDR10+, which is what we are referring to, is very rarely used compared to Dolby Vision, which Samsung has not yet introduced in its televisions. It is also worth mentioning that Samsung DU7192 offers only 82% coverage of the wide DCI-P3 colour gamut, which is another reason we should not supply a signal in wide dynamic range, as colour losses will be very noticeable. Samsung DU7192 provides high-quality images that will satisfy most users.

Panasonic Z95A showcases class when it comes to HDR performance. In luminance tests, it achieves a level of 1800 nits, which has a real impact on movie watching. Scenes from Life of Pi or Gemini Man look fantastic – the television effortlessly renders details and intensity of bright spots, impressing with its power. In more demanding moments, like the final scene from The Meg, one can see how bright light floods the screen. In such moments, brightness drops, which is typical for organic matrices. Nevertheless, a result around 1000 nits can still be considered excellent, still providing very good image quality. Additionally, the television offers excellent coverage of wide colour palettes – as much as 98.6% for DCI-P3 and 74.5% for BT.2020. Thanks to this, colours are not only vivid but also deeply saturated, allowing for a full appreciation of the richness of details, especially in HDR scenes. Such coverage makes the hues look more realistic, and the HDR effect gains in intensity and accuracy. All this impressive HDR effect is thanks to MLA technology, which enables achieving such high luminance and excellent image detail. Because of this, the Panasonic Z95A offers HDR at a level that truly makes a difference.

The best factory mode we used throughout the testing process was "Filmmaker". This, like the vast majority of modes, had its drawbacks. Starting with the most basic chart, which is the white balance, we can notice a pronounced dominance of red, both in SDR and HDR modes. Although there was also some green in the latter, it did not significantly affect the overall impression. A chart with such results, in both cases, gives us an image characterised by strong yellowing, clearly visible on whites and on the faces of the actors. Another important chart, if not more important, is gamma. This, which is meant to control contrast in materials with a standard colour palette, was quite good in factory mode with one caveat regarding the low end. In the darkest scenes, it was significantly lowered, which led to strong brightening, resulting in the film lacking contrast and all suspense. As we mentioned, HDR materials in terms of white balance remained at a similar level. The main change is the EOTF curve chart. At the very beginning, we can observe a bulge, which, just like in the case of gamma, significantly brightened the darkest scenes. However, the chart then changed its characteristics significantly and the measured result dipped below the reference line, causing the film to lose even more dynamics.

The best picture mode on the Panasonic Z95A is undoubtedly the Filmmaker mode. It offers quite a good image reproduction, but it is not free from certain issues that require improvement. Firstly, the white balance, for both 4K and HD content, tends to have a dominance of red and blue hues. This causes a slight pinkish tint to the image, particularly noticeable in bright, white scenes. Such deviations can be seen in the comparative photo below, which illustrates this issue well. The Colour Checker test also confirms these discrepancies, showing slight shifts in the dots towards the mentioned shades.

In terms of gamma brightness characteristics, it performs very well, with only minor problems when brightening small details. A greater challenge is posed by the EOTF curve, which is responsible for controlling brightness in 4K HDR content. Here, there is a slight boost in brightness above the reference value, which sometimes makes the image too bright, especially in more demanding scenes. Although the Filmmaker mode is definitely the best choice on the Z95A, these aspects require refinement to fully utilise the television's potential.

Samsung has equipped even its lowest-end televisions with advanced tools for the calibration process. So we got to work, and the results of our efforts are more than satisfactory. The white balance, which previously had a strong yellow tint in both scenarios, now looks much, much better, even if there are slight deviations from the norm. The image will still look significantly cleaner than it did before the calibration process. We managed to model the gamma in SDR materials very well, ensuring that the image will be as contrasty as the television allows. The EOTF curve has also changed its face and no longer brightens or darkens the image in such a drastic way. However, it's worth mentioning that in the case of HDR materials, deltaE errors are still very high, but this is due to the insufficient brightness of the unit.

After calibration, Panasonic Z95A shows its full potential, offering an almost perfect picture. The television provides immense adjustment capabilities, which we have fully utilised. The white balance after calibration is positively perfect, and errors in SDR content at the level of 0.5 place it in an absolutely reference standard. The same is true for 4K HDR content – the screen tint has been completely eliminated, and the white balance is now exemplary.

The colour palette and Colour Checker test confirm the excellence of the calibration. Errors below 2 are a result that will satisfy both professional calibrators and enthusiasts of cinematic picture quality. Significant changes have also occurred in the brightness characteristic – the EOTF curve has been flattened, eliminating previous issues with excessive brightness. And a small gamma error has been reduced.

Before calibration, the picture was decent, but now it's an entirely different league. It's a real feast for the eyes, the quality of which is hard to compare to anything else. Panasonic Z95A, after fine-tuning the settings, becomes a true master of colour reproduction.

Let's return for a moment to the feature of smoothing tonal transitions. We can set it in only two ways - off and auto. As one can easily guess, the former causes significant problems with gradation. However, if we set the latter, both films and series will offer us smooth transitions of colours. It is worth mentioning, though, that this feature has its drawbacks. It greatly interferes with the director's intent, softens the film grain effect, and, what’s worse, often misinterprets small details, also blurring them. In light of this, we conclude that the feature does not exist and do not recommend using it, as this is exactly how the tests of smoothness of tonal transitions were conducted on the tested display.

The next thing we will check in this paragraph is the image scaling process, which is extremely important when watching materials in a lower resolution. Unfortunately, as this is the manufacturer's lowest model, this function does not work very well. All details are heavily blurred, and a characteristic white halo surrounds the characters.

In the case of lower quality materials, the function "Gradation Smoothing" is responsible for smoothing tonal transitions. The best results are achieved with an intermediate setting – although they are not spectacular, the function works correctly and does not introduce unwanted effects into the image. It can be rated as average, but sufficient to improve the quality of tonal transitions.

As for digital processing, or upscaling, the image looks surprisingly good. It is vivid and pleasant to the eye, which makes lower quality content, such as standard television or YouTube, look quite decent. However, minor issues can be noted, such as "jagged" edges, for example, branches in the background. Nevertheless, this does not significantly affect the overall viewing experience, and the television handles these materials in an acceptable manner.

Despite the fact that Samsung DU7192 is the lowest model in the manufacturer's portfolio, it has been implemented with a motion smoothing system. Although it is quite limited in features compared to higher models, its existence is a considerable advantage in the context of competition from similar price ranges. The maximum refresh rate we will provide to the tested television is 60 Hz, which is entirely sufficient for movies and series, although not for sports. In the motion smoothing menu, we find two functions responsible for improving fluidity. These are "Motion Blur Reduction" and "Clear Motion (LED)". We will discuss the latter a bit later. Let us focus on the former, as it is quite puzzling. Unfortunately, despite its presence, we did not find any usefulness. On each of the settings, the image looked the same, with the characteristic judder known from materials recorded at 24 fps.

The matrix of Samsung DU7192 features an average response time. It is worth mentioning that due to this particular type of matrix, it is better than VA matrices in a similar price range. Therefore, it can be exceptionally said that it will not be the worst in the context of watching sports.

Panasonic Z95A, thanks to its 144 Hz panel, offers excellent image fluidity. For films, there is an "Intelligent Frame Creation" feature that enhances fluidity and reduces motion blur. The user has two sliders at their disposal: "Motion Blur Reduction" – responsible for clearer and sharper details in rapidly moving scenes. "Film Smoothness" – adds fluidity by creating additional frames between the originals, making motion appear smoother and more natural with a "soap opera" effect.

Thanks to this, viewers can adjust the settings to their own preferences. Films and less dynamic material look smooth and natural, which should satisfy most users.

The Samsung DU7192 television is equipped only with HDMI 2.0 ports, which is not surprising given the price of the device and its consumer profile. Therefore, it’s also logical that we won’t achieve maximum quality on the latest generation consoles. Thus, it only has the most basic feature for gamers, which is ALLM. It's a pity that the manufacturer didn’t implement at least GameBar, as it is currently a standard, even in lower-end televisions, and could introduce significant conveniences regarding quick changes to settings.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in terms of support for gamers. The television offers virtually everything one could expect from a device in this bracket. Support for ALLM (automatic low latency mode) and VRR (variable refresh rate) ensures smoothness and eliminates tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and additional support for resolutions other than 4K provides greater flexibility, which is a significant advantage for gamers using various configurations.

A unique and quite specific feature is the "Game Bar." Its ball-shaped interface stands out from the competition and allows for quick adjustments of key settings such as VRR, brightness level, or picture mode, without having to interrupt gameplay.

However, in this class of device, there is a minor disappointment – the Panasonic Z95A offers only two HDMI 2.1 ports, instead of four. This is definitely too few for a premium television, especially at a time when many people own more than one device requiring full HDMI 2.1 support, such as a next-gen console or an advanced computer. In this category, it's hard to accept this limitation, especially given the high aspirations of this model. Nevertheless, the television is an excellent choice for gamers, offering versatility and functionality at the highest level.
