Samsung DU7192 (IPS) vs Panasonic Z95A

The maximum luminance for HDR content on the Samsung DU7192 is 245 nits, but is often exceeded by even lower results. Such values are insufficient for comfortable viewing of HDR material due to the lack of appropriate image dynamics and the colour distortions caused by the device's low brightness. While the manufacturer has equipped the device with an HDR format featuring dynamic metadata, specifically HDR10+, it is rarely used compared to Dolby Vision, which Samsung has yet to introduce in its televisions. It is also worth noting that the Samsung DU7192 only covers 82% of the wide colour gamut DCI-P3, meaning that sending signals in a wide dynamic range should be avoided, as significant colour loss will be evident.

Overall, the Samsung DU7192 delivers high-quality images that will satisfy most users. The television stands out particularly for its vivid colours and decent contrast. Thanks to UHD technology, the image on the screen is sharp and clear, even during fast-moving scenes. The DU7192 also supports HDR, allowing for better reproduction of details in bright and dark areas of the image.

Panasonic Z95A demonstrates class when it comes to HDR performance. In brightness tests, it reaches a level of 1800 nits, which has a real impact on watching movies. Scenes from Life of Pi or Gemini Man look great – the television effortlessly reproduces details and the 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. Nonetheless, a result around 1000 nits can still be considered excellent, still providing very good picture quality. Additionally, the television offers excellent coverage of wide color gamuts – up to 98.6% for DCI-P3 and 74.5% for BT.2020. This ensures that colors are not only vibrant but also deeply saturated, allowing full appreciation of the richness of details, especially in HDR scenes. Such coverage makes colors appear 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. Thanks to 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." However, like most modes, it had its drawbacks. Starting with the most basic chart, the white balance, we observed a pronounced dominance of red in SDR and HDR modes. Although green also appeared in HDR mode, it did not significantly affect the overall perception. This resulted in an image with a noticeable yellow tint, particularly evident on the whites and the faces of the actors.

Another important chart, arguably more significant, is gamma, which controls contrast in materials with a standard colour palette. In factory mode it performed reasonably well, but with one notable issue regarding the darkest scenes. Here, it was significantly lowered, resulting in excessive brightening, which robbed the film of its contrast and suspense.

As for HDR content, the white balance remained similar. The main change occurred in the EOTF curve chart. Initially, we saw a bulge that, like the gamma curve, brightened the darkest scenes considerably. However, the curve then drastically changed, and the measured result dropped below the reference line, diminishing the dynamism of the film even further.

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

In terms of gamma brightness characteristics, it performs very well, with only minor issues when lightening small details. The EOTF curve, which is responsible for controlling brightness in 4K HDR content, poses greater difficulty. Here, a slight boost in brightness above the reference value can be observed, making the image sometimes too bright, especially in more demanding scenes. Although the Filmmaker mode is definitely the best choice in the Z95A, these aspects require refinement to fully exploit the potential of the television.

Samsung even with its entry-level televisions, provides advanced tools for calibration, and we put these to work. The results of our efforts were more than satisfying. The white balance, which previously had a strong yellowish tint in both scenarios, now looks much improved, although slight deviations from the ideal are still noticeable. Nevertheless, the image is significantly cleaner than before the calibration process. We were able to model the gamma well for SDR materials, achieving as much contrast as the television can provide. The EOTF curve has also been adjusted, preventing the image from becoming excessively lightened or darkened. However, it is worth noting that for HDR materials, the deltaE errors remain quite high, with the primary issue being the unit's insufficient brightness.

After calibration, Panasonic Z95A shows its full potential, offering an almost perfect image. The television provides great adjustment capabilities, which we have fully utilized. The white balance after calibration is presented almost perfectly, and errors in SDR content at the level of 0.5 fall within an absolutely reference standard. The same is true for 4K HDR content – any pink tint on the screen has been completely eliminated, and the white balance is now exemplary.

The color palette and Colour Checker test confirm the excellence of the calibration. Errors below 2 is a result that will satisfy both professional calibrators and enthusiasts of cinema-quality images. Significant changes have also occurred in brightness characteristics – the EOTF curve has been leveled, eliminating previous issues with excessive image brightness. And the small error in gamma has been reduced.

Before calibration, the image was acceptable, but now it is a completely different league. It is a true 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 color reproduction.

Let’s revisit the smoothing of tonal transitions function. It can be set to either "off" or "auto." As expected, setting it to "off" results in significant gradation issues. On the other hand, when set to "auto," both movies and TV shows offer smoother colour transitions. However, this function has notable drawbacks: it interferes with the director’s intent by softening the effect of film grain and, more concerning, it often blurs small details, misinterpreting them in the process. For this reason, we consider this feature ineffective and do not recommend using it, as the tests for tonal transition smoothness were conducted with this function turned off.

Next, we assessed the image scaling, which is crucial for watching lower-resolution materials. Unfortunately, as this is one of the manufacturer’s lower-end models, the scaling function does not perform well. The result is heavily blurred details, and a noticeable white halo forms around characters, detracting from the viewing experience.

In the case of lower quality materials, the "Gradient Smoothing" function 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 vibrant and pleasant to the eye, making lower quality content, such as standard television or YouTube, look quite decent. However, minor issues can be noticed, such as "jaggies" on edges, e.g. branches in the background. Nevertheless, this does not significantly impact the overall viewing experience, and the television handles this material in an acceptable manner.

Although the Samsung DU7192 is the entry-level model in the manufacturer’s range, it does come equipped with motion smoothing technology. While this feature is somewhat limited in comparison to higher-end models, its inclusion is a notable advantage in its price category. The maximum refresh rate available on the TV is 60 Hz, which is adequate for movies and TV shows but falls short for fast-moving content like sports.

Within the motion smoothing settings, there are two features aimed at improving fluidity: "Motion Blur Reduction" and "Clear Motion (LED)." We’ll discuss the latter later, but first, let’s focus on the former. Unfortunately, despite being present, we found no noticeable difference when adjusting this setting. Regardless of the chosen option, the picture maintained the same stuttering effect typically associated with 24 fps content.

The Samsung DU7192 uses a panel with an average response time. However, it is worth noting that this type of panel outperforms VA panels in a similar price range, making it a more suitable option for watching sports compared to other budget models.

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

As a result, viewers can adjust the settings to their own preferences. Films and less dynamic materials appear smooth and natural, which should satisfy most users.

The Samsung DU7192 is equipped only with HDMI 2.0 ports, which is to be expected given the device's price point and its target consumer market. As a result, it does not support the highest resolutions or frame rates available on the latest generation consoles. It does, however, feature the basic gaming functionality of ALLM (Auto Low Latency Mode). Unfortunately, it is disappointing that the manufacturer did not include GameBar, a feature that has become a standard even in lower-end TVs. GameBar would have provided significant convenience by allowing gamers to easily adjust settings quickly during gameplay.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in terms of support for gamers. The television offers practically everything one could expect from a device in this category. Support for ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate) ensures smoothness and no tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and the additional support for resolutions other than 4K provides greater flexibility, which is a significant plus for gamers using various setups.

Attention should also be paid to the unique and somewhat specific "Game Bar." Its intuitive interface stands out from the competition and allows quick adjustments to key settings such as VRR, brightness level, or picture mode without interrupting gameplay.

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