Samsung DU7192 (IPS) vs Hisense E7Q / E79Q

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.

The Hisense E7Q / E79Q is a television with average brightness, with a peak luminance level of around 350-380 nits. This is an absolute minimum that allows for HDR content to be viewed in a way that is close to the creators' intentions, although without a distinct "wow" effect. Synthetic test results on white screens have been confirmed in practice – in film scenes, the bright parts of the image are stable and quite uniform, but it's hard to speak of a true "light punch." In everyday use, for example, when watching Netflix or YouTube, the HDR effect is acceptable and is perfectly sufficient for most users. However, it must be stated clearly – this is not the level of top-end screens, and one should not expect that in this price range. Fortunately, the Hisense E7Q / E79Q has an advantage that allows it to gain quite a few points: it features a PFS LED QLED panel, utilising an additional phosphor layer that improves colour reproduction. The measured range of the DCI-P3 colour gamut is about 92%, which means that colours in most scenes are vibrant, well-saturated, and pleasant to the eye, particularly for this price bracket.

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.

In Filmmaker mode, the Hisense E7Q / E79Q television was truly impressive. After the first measurements, it became clear that the white balance was quite well tuned, with the only minor deviation being a slight tendency towards a purple tone, which we mentioned earlier. However, this did not significantly impact the overall character of the image – it remained coherent and pleasant to view. A much larger issue turned out to be the brightness characteristics (gamma) in SDR content and the EOTF curve in HDR films. The television noticeably brightened the image, flattening the contrast and diminishing its depth. Gamma values could drop from the reference 2.4 to around 1.9, making the image look as if it were covered with a thin, milky layer. Fortunately, this is a problem that can be relatively easily corrected through calibration.

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.

The biggest beneficiary of calibration in the case of the Hisense E7Q / E79Q was undoubtedly the SDR mode. It managed to achieve an almost perfect image – most errors in the Color Checker test dropped below a value of 3, and often even 2, which is an outstanding result for this class of equipment. The greatest improvement came from equalising the brightness characteristic (gamma), which meant the image no longer appeared washed out and regained its natural depth. In HDR content, it was also possible to improve colours and eliminate the purple tint mentioned earlier, but errors in the Color Checker measurements were still noticeable. This is due to the fact that – as is often the case with Hisense televisions – the screen manipulates brightness quite heavily, overemphasising some colours. This was also indicated by the EOTF curve, which was slightly above the reference values, suggesting these minor issues with excessive brightness. Despite this drawback and the design limitations that emerge with HDR content, the Hisense E7Q / E79Q gained quite a lot after calibration. In everyday use, the television presents a consistent, natural, and pleasant image, and the difference compared to the factory settings is enormous.

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.

In the case of the Hisense E7Q / E79Q, upscaling and digital image processing are not the strongest aspects of this television. It is evident that the manufacturer has opted more for simplicity rather than advanced image processing algorithms. The television does not offer any features to smooth tonal transitions or systems to improve image clarity, resulting in lower resolution materials looking simply very raw. On the screen, you can notice subtle compression edges that better processors in other models can effectively hide.

During the HD material tests, we noticed that the E7Q tries to artificially enhance detail, which sometimes works, and at other times has the opposite effect – the image becomes soft, slightly blurred, at times even “watery.” There is no aggressive sharpening that ruins naturalness, but there is also no finesse in the detail integration that better image converters offer.

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.

Hisense E7Q / E79Q is a television with a 60 Hz screen, so fans of 4K sports may feel a slight disappointment – we simply won’t see such smooth images here as in more expensive models with higher refresh rates. Fortunately, the situation is much better for films. Cinematic materials recorded at 24 frames per second can be displayed here using a motion smoothing feature, allowing the user to tailor the picture to their own preferences – either more cinematic with visible frames or smoother, in a theatrical style.

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 E7Q / E79Q is truly a successful television for gamers, even though it does not support 4K signal at 120 Hz. The manufacturer, however, has ensured a set of features that until recently could only be found in more expensive models. There is ALLM, meaning automatic switching to low latency mode, allowing the television to activate game mode with very low input lag by itself. We also have VRR, functioning up to 60 Hz – while this may not look impressive on paper, in practice it is fully sufficient, as most games on consoles do not exceed this limit. All these settings can be quickly found in the Game Bar panel, a convenient menu created specifically for gamers. From this interface, one can change picture modes, enable a frame counter, or even... an on-screen reticle – humorously named "target point" in the Vidaa system, which is a result of awkward translation from the Chinese manufacturer.

Special praise should be given to the ability to play in 1080p at 120 Hz, which significantly improves the fluidity and responsiveness of the image. Therefore, if someone wants to play a few titles at a higher refresh rate, they can simply lower the resolution and enjoy much smoother motion. Despite the lack of 4K@120Hz, the Hisense E7Q / E79Q performs really well as a gaming television – especially for those who are not looking for perfection but rather a solid and fast screen for everyday gaming.
