Samsung Q7F vs Dreame S100

Unfortunately, the Samsung Q7F is not one of the brighter televisions, and this has a direct impact on the quality of HDR films. The peak brightness of the panel is just around 250 nits, which is definitely too low to speak of true cinematic experiences. In practice, the image in HDR content does not differ significantly from classic SDR, making it difficult to talk about any "wow effect" that usually accompanies us when watching such films. During tests of film scenes, the image simply looked dark, and the brightness almost always hovered around the aforementioned 250 nits. The worst performances were with shots that included small, intensely shining elements – the global dimming technique used reacted very aggressively in these cases, dimming the entire screen to maintain the effect of black. However, it is worth noting the presence of the QLED coating that expands the colour palette. For a budget QLED model, the Q7F performs quite decently here: the coverage of the DCI-P3 palette is about 93%, and BT.2020 reaches 70%. This means that, despite the low brightness, the colours can still look quite vivid and attractive.

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%.

The factory colour accuracy of the Samsung Q7F is certainly not one of its strong points. In Filmmaker mode, which theoretically should be the closest to neutral, the issue with white balance immediately stands out. There is too much red on the screen, while blue is lacking. The consequences of this are very easy to notice – white, instead of being neutral, takes on warm, almost slightly orange tones. In the long run, this makes the entire image look somewhat unnatural, and bright areas of the scene may seem unrealistic. The problems become even more evident in HDR content. The graphs show that the television has significant errors in the Color Checker palette, which translates to visible inaccuracies in the actual image. Practically, this means that the colours are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, losing their cinematic quality, while bright parts may appear dimmed. As a result, the image seems flattened, and contrast, instead of helping to bring out details, only highlights its own limitations. This is particularly frustrating in HDR material, where every detail matters. In scenes where there should be a subtle play of light and shadow, the Q7F either oversteps by brightening too much or conversely – suppresses elements that should draw the eye. This causes the image to lose its depth, and instead of cinematic realism, we have a rather simplified effect.

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.

After professional calibration, we managed to bring the Q7F into order – at least in terms of SDR content. The picture in this mode looks really good: the white balance has been set correctly, the colours appear natural, and errors in the colour palette have dropped to levels that are practically invisible to the eye. Gamma behaves exemplary, and the only minor drawback is a slight lightening of smaller elements, which results from the lack of local dimming. For everyday watching of television or films in standard quality, the Q7F performs surprisingly well.

It was significantly harder to tame HDR content. Despite adjusting the white balance, the television still heavily manipulates brightness, causing scenes to sometimes look unnatural – what should be subtly darker can be overly brightened, and bright areas of the picture can occasionally appear dimmed. The end result is better than in factory settings, but it is evident that the structural limitations of the Q7F do not allow for the full potential of HDR materials to be fully realised.

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.

Upscaling and digital image processing on the Q7F is a bit of a sine wave. On one hand, we have really nice upscaling – weaker sources look better than one might expect. The image becomes clearer, sharper, and even older films or terrestrial television perform adequately. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… there are some issues. The television has a problem with overscan – part of the image is simply cut off, and it doesn't look very elegant. Additionally, we were let down by a feature called "noise reduction", which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it makes practically no difference – the banding in gradients is still there. It's a bit of a shame, as one could have expected more from a model that is aimed at users looking for a display for SDR content.

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.

Ghosting and motion smoothness in the Q7F are probably the most budget-friendly elements of this television. The 60 Hz panel makes itself known, with noticeable ghosting, especially in dynamic scenes, and it's rather difficult to regard this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, a long trail was left behind, similarly to how a ball in a football match would leave streaks.

On the plus side, the presence of motion smoothing must be acknowledged. In films, it actually makes a difference – especially since most material is recorded at 24 frames per second. Here we can decide whether we prefer a more "cinematic" image, with slight judder typical of cinema, or a smoother, more "television" approach. This part works quite well and helps to improve the viewing experience for series and films.

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 features for gamers in the Samsung Q7F is a topic that evokes a lot of mixed emotions. On one hand – no sensible person expected miracles here, after all, it is a 60 Hz television and it was clear from the start that this would not be hardware for squeezing the maximum out of a console or PC. On the other hand, since the manufacturer promised specific solutions in promotional materials, it is natural that we wanted to see them in practice. Initially, it’s quite good. The automatic game mode (ALLM) works, so there’s no need to manually fiddle with settings; the console switches the television to low-latency mode itself. Additionally, we have the Game Bar, which looks impressive and allows you to check a few basic parameters without leaving the game. And this is where the good news ends.

[UPDATE] We have updated our tests of Samsung televisions from the 2025 model year due to the release of software version 1131, which restored the critical gaming feature HGiG.

The biggest problem with the Q7F is VRR, or rather its absence. Indeed, the relevant icon appears in the menu, it can even be seen in the Game Bar, but throughout the entire test, the function remained inactive and could not be activated in any way. The issue with HGiG is even more painful; this option was actually available at the beginning, but after the software update, it disappeared completely, which is simply irresponsible. Therefore, the Q7F is only suitable for absolute basics. Sure, one can turn on the console, play more relaxed titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television that one buys with gaming in mind, and it’s better to be aware of this before making a purchase.

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.
