Samsung DU7192 (IPS) vs Hisense A7NQ

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 distortions caused by the low brightness of the unit. Although the manufacturer has equipped its device with an HDR format offering dynamic metadata, HDR10+, which is what we're talking about, is very rarely used compared to Dolby Vision, which Samsung has not yet introduced in its televisions. It’s also worth mentioning that Samsung DU7192 offers only 82% coverage of the wide DCI-P3 colour gamut, which is another reason we shouldn't provide a signal in a wide dynamic range, as colour losses will be very noticeable. Samsung DU7192 delivers high-quality image that will satisfy most users.

We checked how the Hisense A7NQ performs with HDR, and there's no surprise here. The luminance chart showed a maximum brightness of 370 nits. The result? Exactly what one could expect – average. At around 350 nits, HDR doesn’t stand out much compared to SDR. Sure, there’s a subtle difference in more brightly lit scenes, but it’s not a show-stopping effect. In terms of wide colour gamut coverage, the result was 92% for DCI-P3 and 70.2% for BT.2020. These are decent values for a TV in this class, which uses a PFS coating – the same one that’s sometimes promoted as QLED. The colours look alright, but don’t expect something that competes with the best screens on the market. HDR on the Hisense A7NQ is more of an add-on than a "game changer". For those looking for solid image quality on a moderate budget – it’s definitely acceptable. However, if we expect full HDR capabilities, it’s worth looking at models from the higher price range.

The best factory mode we used throughout the testing process was "Filmmaker". This, like the vast majority of modes, had its flaws. Starting with the most basic graph, which is white balance, we can notice a significant dominance of red colour, both in SDR mode and HDR. Although in the latter there was also some green, which didn’t have a major impact on the overall perception. A graph 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 graph, if not more important, is gamma. This, which is supposed to control contrast in materials with a standard colour palette, was quite good in factory mode with one "but" regarding the beginning. In the darkest scenes, it was significantly lowered, resulting in strong brightening, which left the film lacking contrast and suspense overall. As we mentioned, HDR materials regarding white balance remained at a similar level. The main change is the EOTF curve graph. At the very beginning, we can observe a bulge, which, just like in the case of gamma, strongly brightened the darkest scenes. However, after that, the graph significantly changed its characteristics and the measured result dived below the reference line, causing the film to lose even more dynamism.

When testing the Hisense A7NQ in Filmmaker mode, we hoped for alignment with the manufacturer's intentions, 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 comparative images speak for themselves – the lead actress in "factory" mode looks cool and pale. It appears as though she has been stripped of life.

As for brightness characteristics, both gamma and the EOTF curve show that the image is overly bright. As a result, everything seems flat, lacking depth and contrast. This state of affairs certainly does not work in favour of the A7NQ and makes the image reception in factory mode leave much to be desired. If we expect natural colour reproduction and appropriate image depth, the A7NQ in Filmmaker mode is unlikely to impress us. It’s a TV that requires significant adjustment to bring out its potential.

Samsung has equipped even its lowest-end TVs with advanced tools for carrying out 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 picture will still look significantly cleaner than it did before the calibration process. We managed to model the gamma in SDR materials very well, allowing the image to be as contrasty as the TV permits. The EOTF curve has also changed its face and doesn’t brighten or darken the image in such a drastic manner. However, it is worth mentioning that in the case of HDR materials, the deltaE errors are still very high, but this is due to the unit's insufficient brightness.

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

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

Let's return for a moment to the tonal transition smoothing function. We can set it in only two ways - off and auto. As you can easily guess, the first of these causes significant issues with gradation. However, if we set the second option, both movies and series will offer us smooth colour transitions. It is worth mentioning, though, that this function has its drawbacks. It heavily interferes with the director's intent, softens the film grain effect, and worse, often misinterprets small details, blurring them as well. Consequently, we consider that this function does not exist and do not recommend using it, as this is how the smoothness of tonal transitions was tested on the tested display.

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

The Hisense A7NQ impresses with its smooth tonal transitions in 4K content, but unfortunately, we won't find any features here that improve this aspect in older, lower-quality materials. In such cases, colour transitions become more noticeable, which can slightly detract from the overall picture quality, especially in scenes with a lot of gradients.

When it comes to upscaling, the television performs surprisingly well. The image is clearly improved, though it comes with certain compromises. It can be seen that the TV adds a touch of artificial sharpness, and background elements, like branches, tend to exhibit slight "jaggies." However, these are details that will mainly catch the eye of those who pay attention to such nuances.

Despite the fact that Samsung DU7192 is the lowest model in the manufacturer's portfolio, it has implemented a motion smoothing system. Although it is quite limited in features compared to higher models, its very existence is a significant plus in the context of competition in a similar price range. The maximum refresh rate that we will give to the tested television is 60 Hz, which is entirely sufficient for films and series, although not when it comes to sports. In the motion smoothing menu, we find two functions responsible for improving smoothness. These are "Motion Blur Reduction" and "Clear Motion (LED)". We'll discuss the latter a bit later. Let's focus on the former, as it is quite mysterious. Unfortunately, despite its presence, we did not find any usefulness. At each of the settings, the picture looked the same, characterised by the typical judder known from materials recorded at 24 fps.

The panel Samsung DU7192 features an average response time. It's worth mentioning that due to this specific type of panel, it is better than VA panels in a similar price range. Therefore, it can be said that it won't be the worst in terms of watching sports.

The Hisense A7NQ is equipped with a 60 Hz panel, which means that dynamic scenes – for example in sports or gaming – come across as rather average here. This is standard in this class of equipment, but it's worth noting 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 works on a 10-point scale. The "judder reduction" option allows you to adjust the smoothness of the image to your own preferences. At the lowest setting, you get a natural film frame rate, which will appeal to cinema purists. Conversely, the maximum setting provides a very smooth, theatrical image, which may be appreciated by those who prefer a more "smeared" motion.

The Samsung DU7192 television is equipped only with HDMI 2.0 ports, which isn’t surprising considering the device’s price and its consumer profile. Therefore, it’s also logical that we won’t achieve maximum quality on the latest generation consoles. That’s why it only features the most basic options for gamers, namely ALLM. It’s a pity the manufacturer didn’t implement at least a GameBar, as this is now standard, even in lower-end TVs, and could offer significant conveniences in terms of quickly changing settings.

Hisense A7NQ is a piece of gear that may pleasantly surprise gamers, although it's not without its flaws. The fact that it has a 60 Hz panel immediately suggests that the TV is not designed for the most demanding gaming scenarios. The motion blur we mentioned earlier can also be a drawback, especially in fast-paced games.

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

A nice addition is the Game Bar, which is clear and practical – all the essential features are at hand without having to dig through the settings. However, it lacks support for HGiG, which could be a disappointment for gamers seeking perfect HDR in games.
