Hisense A6N vs Samsung DU7192 (IPS)

Unfortunately, the quality of HDR effect on A6N is not impressive. A peak brightness of 250 nits does not allow for spectacular effects, and HDR is rather pale, resembling more of a regular SDR. This state of affairs will not satisfy more demanding users who want to enjoy high-quality film materials. Additionally, the color gamut coverage is also not very impressive – DCI-P3 at 82% is an average result that does not fully allow for enjoying vibrant colors in HDR materials.

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.

In the category of color reproduction, the Hisense A6N model in Filmmaker Mode leaves a lot to be desired. Although the name of the mode suggests that we should expect faithful reproduction of cinematic colors, the reality is different – the television has significant problems with image quality. The issue with white balance is particularly noticeable, both for HD and 4K content, which is heavily skewed by the dominance of blue. This results in artificial, cold tones, as clearly seen in the comparative photo below. The Colour Checker test additionally confirms these errors, which are exacerbated by low color gamut coverage. The gamma brightness characteristic shows a serious problem with maintaining a level of 2.4 – the graph is significantly below the reference value, leading to excessive brightness and washed-out blacks. The EOTF curve for 4K content also indicates brightness issues – at the beginning, there is a substantial peak due to the TV's excessive brightness, which negatively impacts image quality. Such image characteristics do not allow for full enjoyment of watching films and require manual adjustment.

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.

Hisense A6N offers options and tools in its settings for correcting numerous image settings that we have utilized. When it comes to white balance, we managed to eliminate the excess blue color – this effect is clearly visible in the comparison photo below, where the boy in the image almost "comes to life." A significant improvement can also be observed in the gamma brightness characteristics – the TV no longer has serious issues with overly brightening the entire image. Unfortunately, the same cannot be said for 4K content, where the EOTF curve could not be fully corrected due to the exceptionally low brightness of this model. For HDR content, we use dynamic tone mapping, which allows for the recovery of many details despite the boosting of mid-tones in the image. In the case of this TV, it provides more benefits than drawbacks. The errors that are still visible in the color palette test and Colour Checker for 4K materials stem from low color gamut coverage and are difficult to eliminate due to the characteristics of the television. Nevertheless, the tonal quality of the image is significantly better, which is why we recommend calibrating the factory settings that are far from ideal.

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.

Let's check how the A6N handles low-quality materials. When it comes to smoothing tonal transitions, the lack of posterization reduction or smoothing of tonal transitions in low-quality materials, such as television or DVD, may be noticeable for more demanding viewers. As for digital processing, the model was presented correctly, and the branches were free of characteristic jaggedness – the image is very plastic and soft, which may appeal to people who prefer this kind of image style.

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.

The 60 Hz panel in the Hisense A6N will likely please those who enjoy watching movies, as the TV offers an "ultra motion smoother," allowing us to adjust the motion blur – either more choppy or smoother, theatrical. As for trailing, it performs quite average – noticeable trailing can be seen, especially on dark backgrounds, which is a rather typical feature in this tier of TVs.

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.

The Hisense A6N is a television that will likely appeal to casual gamers, primarily due to its 60 Hz panel, which may not satisfy more demanding users. Nevertheless, it offers several conveniences that can enhance the gaming experience. The television supports features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Dolby Vision, allowing for better image quality and smoother motion in games that support these technologies. Furthermore, the low input lag ensures quick responses in-game, which is crucial, especially in dynamic titles. With these features, although the television is not the ideal choice for demanding gamers, it provides solid support for those who value comfortable gaming without complicated settings. It is an ideal solution for individuals who want to enjoy gaming without high hardware requirements while still having access to modern technologies that improve the gaming experience.

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.
