Hisense E7Q PRO / E79Q PRO vs Dreame S100

When it comes to the quality of the HDR effect, the E7Q PRO is unfortunately not a television that can impress with brightness alone. In real film materials, we measured around 250–300 nits, which is simply too little for HDR to look spectacular. There is a lack of that "spark" in bright details, highlights, and light effects, and in many HDR scenes, it can resemble good SDR more than true cinematic HDR. The consolation in all this is the colours. We managed to confirm that the E7Q PRO is a PFS-type television, meaning it has an additional filter that improves colour gamut coverage. As a result, even if the brightness does not deliver, the colours in HDR content can be appropriately saturated and pleasing to the eye, without the feeling of a "washed-out" image.

The Dreame S100 is a relatively bright television. In movie mode, the brightness we measured reached around 600 nits. This is a really good result, although not the highest when considering the competition at this price point. In fullscreen scenes, it is evident that the television can produce an image that impresses with its brightness. Unfortunately, when more complex scenes appeared on the screen, the local dimming algorithm in this model primarily focused on maintaining the deepest blacks. However, this came at the expense of HDR performance – and in a drastic manner. In such scenes, the brightness of bright elements dropped below 100 nits, which is a frankly tragic result, far from any HDR effect. One can improve this aspect, but not without a "however." It is simply necessary to change the local dimming setting in the television's menu, but then the blacks in such scenes simply become grey. It's a pity that Dreame couldn't better refine the local dimming algorithms, and the S100 is another example that the sheer number of local dimming zones does not always translate to a better image. As a consolation, it is worth adding that the Dreame S100 is advertised as a "QLED" type television, although in reality it uses a PFS LED filter. As a result, the colours are appropriately saturated, and the colour gamut coverage of DCI-P3 we measured exceeded 94%.

In terms of colour reproduction, we tested the Hisense E7Q Pro in Movie mode, which turned out to be the best built-in preset without a doubt. This mode, unlike the Eco, Standard or Dynamic settings, offers the most natural colours straight out of the box. Although no factory mode is completely free of flaws, the E7Q Pro deserves high praise for its colour rendering in standard SDR content. The colour palette is very well tuned here, and the errors in the Color Checker tests often did not exceed a value of 3, which is an outstanding result rarely seen in such affordable televisions. The only drawback we noted in SDR is the tendency to darken some elements of the image, as indicated by the slightly raised gamma graph. The television performs slightly worse with colours in HDR mode. Here, colour errors become noticeable to the naked eye, mainly due to a lack of blue in the white balance. This causes the colours on the screen to be too warm, and for some viewers, they may even seem “too cinematic.” Of course, to improve these parameters, we proceeded with professional calibration.

We tested the Dreame S100 in 'movie' mode and we definitely recommend using this setting for watching all types of content. Interestingly, within the deeper settings of the television, we also find a dedicated 'Filmmaker' mode, which is now available from almost every manufacturer. However, in the case of the Dreame S100, we do not recommend using it – it blocks all settings related to the picture and does not allow for any configuration in the menu - even motion smoothing. So, how do the factory colours of the S100 fare? Not too badly, but also not the best. The television itself was quite heavily tinted with blue components, which is clearly visible in our white balance measurements. This made the picture artificially brightened, and the colours had a slight bluish tint. This is confirmed by the Color Checker palette, which showed how the colour samples tend to drift towards blue, generating quite significant colour errors. The picture in HDR mode looked definitely better, where the colour errors were not as prominent, although they still fell far from perfection. Here, the white balance was also shifted too much towards blue, causing considerable errors in colour reproduction.

In the case of materials with a 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 is worth noting that the E7Q Pro unit we tested was exceptionally well-made at 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 intervention. The biggest beneficiary of professional calibration was undoubtedly HDR mode. This is where we did the most work, which brought spectacular results. We managed to effectively tame the excessive warmth of the image, caused by a factory deficiency in blue colour. After calibration, the colour errors were reduced to a significantly lower level, which will certainly please those who watch a lot of streaming content in HDR format, expecting faithful reproduction.

The Dreame S100 has proven to be a device very amenable to professional calibration. In its menu, we found a plethora of advanced options that allowed us to effectively correct factory errors. Thanks to advanced white balance correction – both in SDR and HDR content – we completely eliminated the excess blue components. The image immediately became much more natural and pleasant to the eye. After fully tuning the colours, the errors in the Color Checker test dropped below Delta E values of 2-3. For the average viewer, this means that any colour distortions have become nearly impossible to perceive with the naked eye. This is truly a pleasant surprise, as new brands in the television market often encounter significant issues with the correct implementation and functioning of sliders in the calibration menu. Here, everything worked as it should. The only thing we must criticise is the way the television manages its brightness in HDR. Due to the specific nature of the local dimming algorithms, anomalies can be seen on the EOTF curve we measured. Where high highlights should appear, there is a slight boosting of the curve above the reference line. In practice, this causes an unnatural brightening of some of the brightest elements in films or games. Despite this minor flaw, professional calibration brings about a huge, very positive change in this model.

When it comes to upscaling and digital image processing, the E7Q PRO deserves praise. The scaling performs really well and does not dramatically fall behind much more expensive, advanced televisions. Lower-quality materials can look clean and sensible, without the impression that the image is artificially "enhanced." However, the smoothing function presents a bit worse. Indeed, it can be effective and improve tonal transitions in poor quality materials, but at the same time, it can introduce undesirable effects. It sometimes removes grain or adds unwanted artefacts, giving the image a more "digital" character. Therefore, we mainly recommend it to those who prefer a smoother, less cinematic style of image.

For scaling and digital processing in the Dreame S100, the technology that the manufacturer proudly calls Dreamind™ Pro AI is responsible. However, it must be clearly stated that this is not a proprietary processor, but merely a marketing name for a chip made by MediaTek – more precisely, the MT5889 model. Unfortunately, we are talking about a rather outdated unit, from a time when MediaTek lagged significantly behind the competition in terms of performance. This unfortunately has a direct impact on the image as that is what this chip also deals with. The upscaling in the S100 is quite mediocre, and the processor has a tendency to heavily and artificially sharpen edges (fortunately, this can be somewhat tempered with the sharpness slider in the menu). In the options, we also find the "Contour Smoothing" feature, which theoretically is supposed to improve tonal transitions. In practice, it offers almost no improvement – setting it to any level rarely eliminates visible banding of colours, but it can unnecessarily blur elements of the image that should remain sharp.

A separate issue is the phenomenon of overscan (cropping the edges of the frame), which is noticeable here practically all the time. Although there is an option to set the screen to display the full frame in low-resolution materials, this requires activating the previously mentioned Filmmaker mode. And as you know, this mode completely blocks the adjustment of any other sliders in the picture menu. In our test tables, we marked that the television offers an option to disable overscan, as technically such a function exists in the system – however, in everyday use, when maintaining sensible image settings, you will not be able to take advantage of it.

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

When it comes to motion fluidity, the Dreame S100 performs really well. It features a panel with a refresh rate of 144 Hz, although in reality, the vast majority of people using it in a traditional way will still be limited to 120 Hz (as this is the maximum supported by today's equipment apart from PCs). Thanks to the high refresh rate, the image in motion remains really sharp, largely thanks to the well-functioning MEMC smoother. In the menu, we find predefined modes that allow the television to efficiently generate artificial frames, which effectively improves the fluidity of dynamic sports scenes, but also eliminates image stuttering in film and series materials recorded at 24 frames.

The E7Q PRO is a phenomenal screen for gamers. Aside from the typical "ache" of Hisense, which is the lack of support for the HGiG format due to permanently active tone mapping, we get practically everything one can expect from a television that is to have a gaming label. There are two HDMI 2.1 ports, along with a full set of key features. We have variable refresh rates, automatic switching to game mode, and support for 4K at 120 Hz. Additionally, all the most important settings are at hand in a clear Game Bar. This tool not only looks modern but also has a typically "gaming" edge and truly makes life easier while gaming.

The Dreame S100 seems almost like the perfect screen for a gamer. The television is equipped with 2 HDMI 2.1 ports with a bandwidth of 40 Gbps, which means that functions like automatic game mode (ALLM) and variable refresh rate (VRR) ranging from 48 to 144 Hz work seamlessly on consoles. It also features a well-designed gaming panel (Game Bar), allowing users to continuously monitor important parameters—from active picture modes to the number of frames rendered by the console, and even the option to add a crosshair in the middle of the screen. All of this looks great on paper; however, the biggest problem with the S100 is the implementation of HDR mode in games. The television does not have the HGiG format implemented correctly. As a result, an unsuspecting user may incorrectly configure the console when first using the screen. Poor configuration can lead to an image that is too dark or too washed out (as a guideline: we suggest setting the brightness in the Xbox console menu to around 600 nits, and in the PS5 to 12 clicks). The Dolby Vision format also proves problematic, as it often would not activate at all between the XBOX and Dreame S100. And when it was finally managed to be activated, playing was not possible due to a very high input lag often exceeding 100ms. If the manufacturer can improve the HDR issue in games via an update, the S100 will be truly excellent hardware for gamers. For now, however, compromises need to be accepted.
