Samsung DU7192 (IPS) vs Hisense E7Q PRO / E79Q PRO

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.

When it comes to HDR effect quality, the E7Q PRO unfortunately is not a television that impresses with brightness alone. In real film materials, we measured around 250–300 nits, which is simply not enough for HDR to look spectacular. There's a lack of that "spark" in bright details, flashes, and light effects, and in many HDR scenes, it can resemble more of a good SDR than true cinematic HDR. The silver lining in all this is the colours. We managed to confirm that the E7Q PRO is a PFS type television, which means it has an additional filter that improves colour gamut coverage. Because of this, even if the brightness doesn't deliver, the colours in HDR content can be properly saturated and pleasing to the eye, without the impression of a "washed-out" image.

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.

In terms of colour reproduction, we tested the Hisense E7Q Pro in Movie mode, which undoubtedly turned out to be the best built-in preset. It is this mode, unlike the Eco, Standard, or Dynamic settings, that offers the most natural colours straight out of the box. While no factory mode is completely free of flaws, the E7Q Pro deserves high praise for its colour rendition in standard SDR content. The colour palette has been very well tuned, and errors in the Color Checker tests often did not exceed a value of 3, which is an outstanding result rarely seen in such affordable TVs. The only drawback we noted in SDR is the tendency to darken certain elements of the image, as indicated by a slightly raised gamma curve. The TV performs slightly worse with colours in HDR mode. Here, colour errors become noticeable to the naked eye, mainly due to a deficiency of blue in the white balance. This causes the colours on screen to appear too warm, and for some viewers, they may seem almost "too cinematic." Of course, to improve these parameters, we proceeded with professional calibration.

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.

In the case of materials with standard dynamic range (SDR), our actions in Filmmaker mode turned out to be largely cosmetic 😉. We mainly focused on a subtle adjustment of the white balance and equalising the gamma curve, which allowed us to recover details in the darker areas of the image that previously tended to get lost. However, it's worth noting that the E7Q Pro unit we tested happened to be exceptionally well-made from the factory. We remind you that these parameters depend on the specific unit – with mass production, factory calibration can be random, so your unit may require slightly different adjustments. The biggest beneficiary of professional calibration was undoubtedly HDR mode. This is where we did the most work, which brought spectacular results. We successfully tamed the excessive warmth of the image, caused by a factory shortfall in blue colour. After calibration, colour errors were reduced to a significantly lower level, which will certainly please those watching a lot of streaming content in HDR format, expecting faithful reproduction.

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.

When it comes to upscaling and digital image processing, the E7Q PRO deserves praise. The scaling performs really well here and doesn't fall dramatically short of much more expensive, advanced TVs. Lower quality materials can look clear and reasonable, without the impression that the image is artificially "overdrawn." The smoothing function, however, presents a bit worse. Yes, it can be effective and improve tonal transitions in low-quality materials, but at the same time, it can introduce unwanted effects. Sometimes it removes film grain or adds unwanted artifacts, giving the image a more "digital" character. Therefore, we mainly recommend it to those who prefer a smoother, less cinematic image style.

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.

In the category of motion blur and fluidity, the E7Q PRO has one very strong argument. At this price, Hisense has added a 120 Hz panel, and in PC mode, it can even operate at 144 Hz. This immediately provides greater possibilities in motion settings, as more options for smoothing the image appear in the menu. Among other things, we have frame interpolation options, allowing us to adjust the fluidity for sports or movies, depending on whether we prefer a more cinematic character or a "theatrical" smoothness.

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.

E7Q PRO is a phenomenal screen for gamers. Besides the typical "issue" with Hisense, which is the lack of support for the HGiG format due to constantly active tone mapping, we get practically everything one could expect from a TV that is supposed to have a gaming tag. There are two HDMI 2.1 ports, along with a full set of key features. We have variable refresh rate, automatic switching to game mode, and support for 4K at 120 Hz. On top of that, all the important settings are at hand in the clear Game Bar. This tool not only looks modern, but it also has a typically "gaming" edge and actually makes life easier while gaming.
