Hisense S7NQ CanvasTV vs Dreame S100

When it comes to the brightness of the television and how it handles bright elements while watching films, it is simply average – similar to the case with contrast. The average brightness level of the Hisense S7NQ is around 500 nits. This is a value that allows one to feel the beginnings of true HDR, but it is definitely too little to speak of remarkable effects. However, the television should be praised for its colour gamut coverage – films look very colourful and vibrant. Thanks to the use of PFS LED (QLED) coating, the device is capable of covering over 90% of the DCI-P3 colour palette and over 72% of the wider BT.2020 palette. For a television of this class – these are really very good results.

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%.

Let's now check how the Hisense S7NQ CanvasTV performs in colour reproduction in the best factory mode, which is Filmmaker. Right from the start, it is clear that it is decidedly better than in dynamic or standard modes, but there are still a few things to nitpick. Regarding image quality from an HD signal, the colours are slightly inaccurate – there is a dominance of cooler shades of blue and a lack of red. This makes the image appear somewhat too cool.

A similar effect can also be observed with 4K content, but there it is much more noticeable. The excessive exposure of blue tones and the lack of red result in the image appearing distinctly cold. However, the biggest problem with this television is not the colours themselves but the way brightness is managed. The tested unit slightly boosted brightness compared to the reference value. While this results in better visibility of details, it comes at the cost of significantly brightened blacks – causing the entire image to seem more "flat".

A similar phenomenon was noticed in the 4K signal – the slightly elevated curve at the beginning of the EOTF chart shows that the television has a tendency to overexpose certain scenes. Fortunately, this effect can be improved with professional calibration, which we will discuss in the next point.

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.

The results we achieved after calibrating the Hisense S7NQ are really very good. Thanks to the calibration, we managed to eliminate the excessive exposure of blue tones and deficiencies in red with HD signal. A similar, albeit slightly weaker effect was also achieved with 4K HDR content. Managing brightness in HD material has also been improved – the television no longer has issues with brightening the image "across the board."

However, there are things that cannot be bypassed. The characteristic of the EOTF curve has practically not changed, and the lack of local dimming means that the smallest elements on the screen will always be slightly overexposed. One simply has to come to terms with this when choosing a television with a similar type of backlighting. Despite this, the final effect is very good and should fully satisfy the vast majority of users.

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.

Equally important is how the television handles tonal transitions on a poor signal – for example, in older films, television, or on YouTube. Unfortunately, despite the presence of the "Smooth and Gradient Picture" feature, which was supposedly meant to improve this aspect, its performance is truly poor. It's barely noticeable that it has any real impact on the visibility of colour transitions.

The image scaling is also lacking. Yes, it can be observed that the television tries to "enhance" the quality, but the end result is far from ideal. The image often appears slightly jagged, which is particularly noticeable in the example of tree branches in the background. Additionally, the Hisense S7NQ has a clear tendency to crop the image at lower resolutions, causing subtitles in news items or finer details in the image to be missed.

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.

When it comes to motion fluidity, the television performs remarkably well. Although the S7NQ was designed primarily for displaying static elements – such as images – the manufacturer has implemented a 144 Hz refresh rate matrix. As a result, sports and games look really good on it.

For materials that are not recorded at a high frame rate, the manufacturer has provided two features that allow you to adjust the picture to your own preferences. "Motion blur reduction" and "judder reduction" operate on a 10-point scale, allowing you to choose between a more cinematic image – with characteristic frame jumps – and a smooth effect reminiscent of a "soap opera". How to set this up? That’s a personal matter – we leave the decision to you.

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.

Although the S7NQ is a "picture" type television, it can indeed be used for gaming. Really. Here you can find almost everything (except for the HGiG mode) that a modern gaming television needs. The 144 Hz panel and two full-fledged HDMI 2.1 ports allow for the hassle-free connection of two consoles, such as the PlayStation 5 or Xbox Series X/S.

The television supports Automatic Low Latency Mode (ALLM) and Variable Refresh Rate (VRR), with no stuttering or issues. It also handles displaying high frame rates at lower resolutions without any trouble. Hisense deserves praise for a very attractive Game Bar – it displays all available picture options, and additionally, we have the ability to enlarge the minimap or turn on the crosshair (because sometimes someone might actually want to "aim" 😉).

The only missing element – as we mentioned earlier – is the lack of a proper implementation of the HGiG mode. It is specifically responsible for automatically adjusting the picture in games as the creators intended. It's a shame, because that’s the only thing preventing the Hisense S7NQ from being a full-fledged gaming "beast".

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.
