Hisense U7Q PRO vs Dreame S100

U7Q PRO is truly a bright television. In synthetic tests, it achieved over 1500 nits, which is an outstanding result for this price range. Such brightness – at least in theory – allows for displaying HDR content as intended by creators, even in more demanding scenes with strong light. In practice, it can be very good, but not always perfect. In bright scenes with a large surface area – such as the test screen with intense sunlight from the movie "Pan" – U7Q PRO makes a huge impression. It can almost blind with light, which is definitely an advantage in the context of HDR content. Unfortunately, this is not always maintainable when a lot of small bright details appear on a dark background. In such moments, local dimming algorithms decide to dim some bright elements to maintain good black levels – and the side effect is that some details simply disappear from the frame. This is a classic compromise in mini-LED televisions – and U7Q PRO is no exception. However, with such a large number of dimming zones, one could expect a somewhat more mature algorithm responsible for controlling them. Fortunately, the overall reception of HDR content is very positive. U7Q PRO is not only bright but also colorful; thanks to the PFS LED (QLED) coating, the coverage of the DCI-P3 color palette is at 95%, and BT.2020 is around 73%.

The Dreame S100 is a relatively bright television. In movie mode, the brightness we measured reached about 600 nits. This is a really good result, although not the highest, considering the capabilities of the competition in this price range. In fullscreen scenes, it is evident that the television can generate an image that strikes with brightness. Unfortunately, when more complex scenes appeared on the screen, the local dimming algorithm in this model tried above all to maintain the deepest blacks. However, this came at the expense of HDR effect – and in a drastic way. In such scenes, the brightness of bright elements dropped below 100 nits, which is a truly tragic result, far from any HDR effect. This aspect can be improved, though not without any "buts." It is enough to change the local dimming setting in the television's menu, but then the blacks in such scenes simply turn gray. It’s a pity that Dreame could not refine the local dimming algorithms better, and the S100 is another example that the mere number of local dimming zones does not always translate into better image quality. As a consolation, it is worth adding that the Dreame S100 is advertised as a "QLED" television, although in reality it utilizes a PFS LED filter. As a result, the colors are appropriately saturated, and the color gamut coverage we measured exceeded 94% of the DCI-P3 palette.

We tested the U7Q PRO in the best possible picture mode that this model offers – Filmmaker Mode. And indeed, it is this mode that performs best in terms of color reproduction. But that doesn't mean it's perfect. In our test unit, both in SDR and HDR content, the image had a slightly cooled tone. The white balance was shifted towards blue, which made the overall impression feel a bit "cooler." It's not glaring, but definitely noticeable – especially on white backgrounds that, instead of neutral, appeared slightly bluish. Additionally – as we mentioned earlier – the television tends to slightly brighten and oversaturate the image, which is also confirmed by the gamma and EOTF charts. All of this together means that without calibration the image may seem a bit unnatural – too cool, with slightly exaggerated dynamics. That's why we decided to conduct our own calibration – and its effects and charts can be seen below.

We tested the Dreame S100 in "movie" mode and definitely recommend using this setting for watching all kinds of content. Interestingly, in the deeper settings of the TV, we also find a dedicated "Filmmaker" mode, which is available today from almost every manufacturer. However, in the case of the Dreame S100, we do not recommend using it – it blocks all image-related settings and does not allow any configuration in the menu - not even motion smoothing. So how do the factory colors perform on the S100? Not too bad, but also not great. The TV itself was quite heavily tinted with blue components, which is clearly visible in our white balance measurements. This caused the image to be artificially brightened, and the colors had a slight bluish tint. This is confirmed by the Color Checker palette, which showed how color samples leaned towards blue, generating quite significant color errors. The image in HDR mode looked definitely better, where color errors were not as prominently visible, though they still fell far from ideal. Here, the white balance was also too heavily skewed towards the blue color, which caused quite significant errors in color reproduction.

Thanks to calibration, we managed to tame the white balance in both SDR and HDR content. For SDR materials, the effect is really very good – the image becomes neutral, consistent, and simply pleasant to view. Everything looks as it should.

The performance in HDR is a bit worse. Although the white balance looks correct and overall the image gains in naturalness, unfortunately, delta E errors remain noticeable. Why? Because Hisense does not give us full control over how the U7Q PRO manages brightness in HDR mode. This is where the limitation appears. When we look at the EOTF curve for HDR content, we can clearly see what we mentioned earlier – at the beginning of the graph, there is a noticeable drop, meaning the television dims the smallest sections more than it should. On the other hand, the brightest elements can be illuminated a bit too much. As a result, some details are lost, others are too aggressive, and overall control over brightness does not always align with what we are trying to achieve during calibration.

Does the image look better after calibration? Definitely yes, in terms of color. But when it comes to managing brightness in HDR, we have to accept that the Hisense U7Q PRO will do it its own way.

The Dreame S100 turned out to be a device very susceptible to professional calibration. In its menu, we found a whole array 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 excess blue components. The image immediately became much more natural and pleasant to view. After fully tuning the colors, errors in the Color Checker test dropped below Delta E values of 2-3. For the average viewer, this means that any color distortions have become nearly impossible to notice with the naked eye. This is a really nice surprise, as often new brands in the television market have significant problems with proper implementation and functioning of sliders in the calibration menu. Here, everything worked as it should. The only thing we need to criticize is the way the television manages its brightness in HDR. Due to the specific nature of the local dimming algorithms, we observed anomalies in the EOTF curve we measured. In the areas where high highlights should appear, there is a slight uplift of the curve above the reference line. In practice, this results in unnatural brightening of some of the brightest elements in movies or games. Despite this minor flaw, professional calibration brings a huge, very positive change to this model.

If someone happens to come across older materials where the issue of color banding appears – Hisense has a solution for that. In the U7Q PRO, we find a feature called "Smooth and Gradient Picture." Set to the "Medium" level, it works really well – it eliminates most of the gradation issues while not smoothing out the entire image, like blur in Photoshop. 😉 Film grain remains, details do not disappear – this is exactly how it should work. Kudos for the implementation!

As for scaling weaker materials, it’s just good. It’s not at the level of the most expensive TVs with advanced upscaling, but older content looks good. There is some mild aliasing at very low resolutions, but that’s completely normal and hard to avoid. On the plus side – even with the oldest materials, there is no overscan effect; the image is not cropped or artificially stretched.

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

A separate problem is the phenomenon of overscan (clipping the edges of the frame), which is almost always visible here. Although there is an option to set the screen to display the full frame in low-resolution materials, it requires activating the aforementioned Filmmaker mode. And as you already know, this mode completely blocks any other adjustments in the image menu. In our test tables, we noted that the television offers the option to disable overscan, as technically such a feature exists in the system – however, in everyday use, with reasonable image settings, you will not be able to take advantage of it.

“Speed” – this word was mentioned most frequently during our tests of the U7Q PRO. The television is equipped with a 165 Hz panel, which is impressive in itself – especially since we are talking about a model in the mid-price range. Of course, PC gamers will benefit the most from its full capabilities, but even during everyday viewing, it is evident that this is a fast and efficient panel. Like most modern televisions, the U7Q PRO can also enhance the smoothness of movies that are primarily shot in 24 frames. In the menu, there is a slider that allows you to adjust the effect to your preferences – from a more cinematic feel, with subtle motion, to stronger smoothing with the characteristic “soap opera effect.”

When it comes to motion fluidity, the Dreame S100 performs really well. It features a panel with a 144 Hz refresh rate, although in reality, the vast majority of users using it in a traditional way will still be limited to 120 Hz (because today's equipment, apart from PCs, only allows for such values). Thanks to the high refresh rate, the image in motion remains really sharp, largely due to the well-functioning MEMC fluidity enhancer. In the menu, we find predefined modes that allow the TV to efficiently add artificial frames, which effectively improves the fluidity of dynamic sports shots, but also helps get rid of image stuttering in film and series materials recorded at 24 frames.

The Hisense U7Q PRO is a television that seems almost designed for gamers. It has practically everything you could expect from a gaming screen: variable refresh rate (VRR), automatic mode (ALLM), and as many as four HDMI 2.1b ports with full bandwidth of 48 Gb/s. Additionally, there is a clear and quite functional Game Bar, as well as a well-implemented Dolby Vision GAMING mode that works seamlessly with Xbox Series S and X consoles.

Sounds like perfection? Well, almost. Unfortunately, Hisense has yet to implement the HGiG feature, which is the system's limit on tone mapping on the TV's side. This means that when configuring HDR brightness on the console, we do it "by eye" or look for settings in online guides because the screen doesn't show the real range of its brightness. It's a pity - because HGiG makes it easier to match the console to the TV and helps avoid clipping or overly dark scenes in HDR games.

Fortunately, the other elements work very well. Signal delay (input lag) is low, responsiveness is excellent, and the handling of other functions is flawless. And although not everything worked perfectly, the U7Q PRO can still be recommended to gamers without hesitation.

The Dreame S100 seems almost like the perfect screen for gamers. The TV is equipped with 2 HDMI 2.1 ports with a bandwidth of 40 Gbps, which means that features such as Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) synchronization in the range of 48-144 Hz work seamlessly on consoles. It also has a well-designed game panel (Game Bar) that allows you to continuously check the most important parameters – from active picture modes to the number of frames rendered by the console, and even the ability to add a crosshair in the center of the screen. All of this looks great on paper, but the biggest issue with the S100 is the implementation of HDR mode in games. The TV does not have a properly implemented HGiG format. As a result, an unsuspecting user may incorrectly configure the console during the initial setup of the display. A wrong configuration can lead to a picture that is too dark or too bright (as a guideline: we suggest setting the brightness in the Xbox console menu to about 600 nits, and in the PS5 to 12 clicks). The Dolby Vision format is also problematic; it often just would not activate at all when using the XBOX – Dreame S100 line. And when it was managed to be activated, gaming was impossible due to a very high input lag that often exceeded 100ms. If the manufacturer can improve the HDR issue in games through an update, the S100 will be truly excellent equipment for gamers. For now, however, one must reckon with compromises.
