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 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.

We checked how the Hisense A7NQ performs with HDR, and there are no surprises here. The luminance graph showed a maximum brightness level of 370 nits. The result? Exactly what one could expect – average. At around 350 nits, HDR does not particularly stand out compared to SDR. Indeed, there is a subtle difference in more brightly lit scenes, but it is not an effect that leaves you stunned. As for the coverage of the wide colour gamut, 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 is sometimes promoted as QLED. Colours look good, but we shouldn’t expect something 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 image quality on a moderate budget – quite acceptable. However, if we expect full HDR capabilities, it is 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 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.

When testing the Hisense A7NQ in Filmmaker mode, we were hoping for compliance with the manufacturer's assumptions, but unfortunately, reality looks different. The main issue, as with most televisions, is 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 results of the Color Checker tests confirm this, and the comparative images speak for themselves – the leading actress in "factory" mode appears cool and pale. It looks as if she has been drained of life.

As for brightness characteristics, both gamma and the EOTF curve show that the image is excessively bright. As a result, everything appears flat, lacking depth and contrast. This state of affairs definitely does not work in favour of the A7NQ and makes the viewing experience 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 is a television that requires considerable adjustment to bring out its 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.

Hisense A7NQ offers several tools that allow for improved 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 colour in both HD and 4K materials. This is a significant step forward, as in the Color Checker test, the colour reproduction errors in lower quality content dropped to a much more acceptable level. Unfortunately, the 4K materials still fall short of perfection – the colour inaccuracies are considerable 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 brightness characteristics in 4K content remains unresolved – the EOTF curve still shows excessive brightness across the entire screen. It’s possible that correct implementation of dynamic tone mapping could help here, but as we mentioned earlier, this feature in the Hisense A7NQ works rather poorly, rather than being helpful. Nevertheless, the calibration has significantly improved the overall image reception. The director's vision is now much better represented than in the factory settings, which will certainly be appreciated by more demanding viewers.

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.

The Hisense A7NQ impresses with the smoothness of tonal transitions in 4K content, but unfortunately, there is no feature here to improve this aspect in older materials of lower quality. In such cases, colour transitions become more visible, which can slightly detract from the overall image, especially in scenes with a lot of gradients.

When it comes to upscaling, the television performs surprisingly well. The image is noticeably improved, although there are some compromises. It can be seen that the television adds a bit of artificial sharpness, and background elements, such as branches, display slight "jaggies." However, these are details that will primarily 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 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.

The Hisense A7NQ is equipped with a 60 Hz panel, which means that dynamic scenes – for example in sports or games – perform rather averagely here. This is standard for this class of equipment, but it must be acknowledged that watching more intense, fast-moving content can leave a lot to be desired. However, when it comes to films, the television offers a motion smoothing feature that operates on a 10-point scale. The "judder reduction" option allows you to tailor the smoothness of the image to your own preferences. At the lowest setting, we get a natural film frame rate, which will please cinema purists. Meanwhile, the maximum setting provides a very smooth, theatrical image that may appeal to those who prefer a more "smoothed" motion.

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.

Hisense A7NQ is a piece of equipment that can pleasantly surprise gamers, although it is not without its flaws. The fact that we have a 60 Hz panel here immediately suggests that the television is not designed for the most demanding gaming scenarios. The motion blur that we described earlier can also be an obstacle, especially in dynamic games.

However, there are a few things that are worth praising. The television supports ALLM (automatic game 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 images at 120 Hz – albeit only in Full HD resolution, but nevertheless, it's a significant nod to gamers. This provides the option to choose between smoothness and resolution, which is not obvious in televisions at this price.

A nice addition is the Game Bar, which is clear and practical – all the most important functions are at hand, without digging through the settings. However, it lacks support for HGiG, which may be a disappointment for gamers looking for perfect HDR in games.
