Samsung DU7192 (IPS) vs Hisense A7NQ

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.

We checked how the Hisense A7NQ performs with HDR, and there are no surprises here. The luminance chart showed a maximum brightness of 370 nits. The result? Exactly what one could expect – average. At a brightness of around 350 nits, HDR does not stand out particularly compared to SDR. Yes, a subtle difference can be seen in more brightly lit scenes, but it’s not a jaw-dropping effect. As for the coverage of the wide color gamut, the result was 92% for DCI-P3 and 70.2% for BT.2020. These are decent values for a TV in this class that uses an PFS coating – the same one that is sometimes promoted as QLED. Colors look good, but let’s not expect anything that competes with the best screens on the market. HDR on the Hisense A7NQ is more of an addition than a "game changer." For those looking for solid picture quality on a moderate budget – absolutely acceptable. However, if we expect full HDR capabilities, it is worth looking at higher-end models.

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.

When testing the Hisense A7NQ in Filmmaker mode, we hoped for compliance with the manufacturer's assumptions, but unfortunately, reality looks different. The main issue, as with most TVs, is the white balance. In the case of the A7NQ, we noticed a clear dominance of blue, which affected both lower quality materials and 4K HDR content. The Color Checker test results confirm this, and the comparison images speak for themselves – the main actress appears cool and pale in "factory" mode. It looks as if she has been stripped of life.

Regarding brightness characteristics, both gamma and the EOTF curve show that the image is excessively bright. As a result, everything seems flat, lacking depth and contrast. This state of affairs definitely does not work in favor of the A7NQ and makes the viewing experience in factory mode leave much to be desired. If we expect natural color reproduction and appropriate image depth, the A7NQ in Filmmaker mode is unlikely to impress us. It is a TV that requires significant adjustment to extract its potential.

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.

The Hisense A7NQ offers several tools that allow you to improve image quality, so we decided to take matters into our own hands and "dig around" in the settings a bit. Thanks to professional tools and measurements, we managed to correct the white balance, eliminating the excessive dominance of blue color in both HD and 4K materials. This is a significant step forward, as in the Color Checker test, color reproduction errors in lower quality content dropped to a much more acceptable level. Unfortunately, 4K materials are still far from ideal – color distortions are considerable and stem from the limitations of the television.

As for gamma, we managed to set it at the correct level, which significantly reduced excessive brightness of the image. However, the issue with brightness characteristics in 4K content remains unresolved – the EOTF curve still shows excessive illumination of the entire screen. It is possible that a proper implementation of dynamic tone mapping could help here, but as we mentioned earlier, this feature on the Hisense A7NQ works rather poorly instead of being helpful. Nevertheless, calibration significantly improved the overall image perception. The director's vision is now much better conveyed than in the factory settings, which more demanding viewers will certainly appreciate.

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 Hisense A7NQ impresses with smooth tonal transitions in 4K materials, but unfortunately, there is no feature here that would improve this aspect in older materials of lower quality. In such cases, color merging becomes more visible, which can somewhat spoil the viewing experience, especially in scenes with a lot of gradients.

When it comes to upscaling, the TV performs surprisingly well. The image is clearly improved, although it does come with some compromises. One can notice that the TV adds a bit of artificial sharpness, and elements in the background, such as branches, tend to exhibit slight "jagginess." These are details, however, that will mainly catch the eye of those who pay attention to such nuances.

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 A7NQ is equipped with a 60 Hz matrix, which means that dynamic scenes – for example, in sports or games – are somewhat average here. This is standard for this class of equipment, but it must be admitted that watching more intense, fast-moving content can leave a lot to be desired. However, when it comes to movies, the TV offers a motion smoothing feature that operates on a 10-level scale. The "motion blur reduction" option allows you to adjust the fluidity of the image to your own preferences. At the lowest setting, you get a natural film frame rate, which will please cinema purists. On the other hand, the maximum setting provides a very smooth, theatrical image that may appeal to those who prefer a more "smoothed out" motion.

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.

Hisense A7NQ is a device that can pleasantly surprise gamers, although it is not without its faults. The fact that we have a 60 Hz panel immediately suggests that the TV is not designed for the most demanding gaming scenarios. The motion blur we described earlier can also be a hindrance, especially in dynamic games.

However, there are several things worth praising. The TV supports ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), which are not always standard in this price range. The biggest surprise, however, is that the A7NQ can display images at 120 Hz – although only in Full HD resolution, it is still a significant nod to gamers. This allows a choice between smoothness and resolution, which is not obvious in TVs at this price point.

A nice addition is the Game Bar, which is clear and practical – all the main features are at hand without digging through the settings. However, there is a lack of support for HGiG, which may be disappointing for gamers looking for perfect HDR in games.
