SONY BRAVIA 3 vs Dreame S100

Bravia 3 does not hide the fact that it belongs to the group of televisions that are rather modest in terms of brightness. Our measurements showed around 370 nits, which is a value teetering on the edge of where one can still speak of any HDR effect. For some, this is an acceptable level, while for others it is rather typical for SDR content, where spectacular highlights or vivid contrasts are not expected. The impression is that this is not a television for those focused on the highest image quality in demanding cinematic content. However, this does not mean that we cannot find any advantages here. Compared to its predecessor, the X75WL, Bravia 3 has gained an additional PFS filter, which works similarly to solutions known from QLED technology. Thanks to this, the DCI-P3 colour palette has been significantly widened and reaches over 91 percent, which in practice results in more saturated colours and a more pleasing image texture. As a result, even everyday content looks somewhat livelier, and films and series can surprise with vibrant visuals, despite limitations in brightness itself.

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%.

Sony Bravia 3 was primarily tested in film mode, which immediately proved to be the best choice among the factory settings. It is not a perfect picture, but compared to the eco mode that the television offers right out of the box, the difference is clear and positive. In film mode, one can notice a certain problem: the image appears too warm, which results from a lack of blue colour in the white balance. Despite this, in SDR content, the final effect can still be considered quite decent and satisfactory for everyday viewing. Much more serious errors occur in HDR materials. The Color Checker analysis showed considerable deviations, and poor brightness management, combined with limited colour gamut coverage, further exposes the shortcomings of the image in this mode. All of this makes HDR on the Bravia 3 appear unconvincing and can spoil the impression left by the quite decent SDR content setting. Fortunately, this is not an insurmountable situation. Various errors can be somewhat mitigated, and some can even be fully corrected through professional calibration. Therefore, we decided to check how the television would perform after such adjustments.

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 calibration allowed us to extract significantly more from the Bravia 3 than we could have expected at the beginning. Firstly, it managed to compensate for the deficiency of blue, which had previously caused a noticeable warming of the image. After a slight adjustment to the white balance, most of the errors in the Color Checker measurements for SDR content virtually disappeared. The white tones became more natural, and the brightness management in gamma stabilised to an almost ideal level, not exceeding the threshold of human perception. Thus, it can be confidently stated that in SDR content, after a few adjustments to the settings, the Bravia 3 performs remarkably well. Significantly worse, although still definitely better than before calibration, are HDR contents. The white balance was brought into order, however, the limitations of the IPS panel are insurmountable. The lack of local dimming means that even the smallest elements can be overexposed, which immediately stands out. Colour-wise, the effect is also improved, though far from perfect – many errors still exceed the threshold of four or even five delta E units, meaning they remain visible to the human eye. It was already clear earlier that the Bravia 3 is not a television designed to impress with HDR quality. Nevertheless, it is gratifying that in SDR content, after calibration, the image can look truly excellent, and in this category, the television pleasantly surprised us.

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.

Bravia 3 brings something more to the Sony TV family than just a shared name. It stands out primarily for its ability to enhance the quality of weaker materials thanks to the processor used. Of course, we won’t find the advanced XR chip known from more expensive models here, but even so, it must be admitted that the image in lower resolutions looked surprisingly good. The scaling worked effectively, and most parts of the screen were free from the typical excessive edge tearing found in budget constructions.

Attention should also be paid to the function that improves the smoothness of tonal transitions. In the high setting, it works really well, effectively masking gradation imperfections without significant detail loss. It does happen, however, that the algorithm overly smooths elements that should remain sharp – for example, faces – but overall, the effect is beneficial. The best results were achieved precisely at the highest setting, and this option could be recommended to those watching lower quality 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.

The fluidity of motion has never been a strong point of televisions equipped with 60 Hz panels, and the Bravia 3 is no exception. Nevertheless, Sony has added something that may appeal to those more sensitive to the way images are displayed. We are talking about the proprietary motion smoother, Motion Flow, which offers users a considerable range of adjustment options. Thanks to it, one can make the image smoother, even theatrical, or stick to a more cinematic style with the characteristic judder that many simply associate with the filmic atmosphere. These functions work with content at lower frame rates, such as films and series recorded at 24 or 30 frames per second, which are the materials we encounter on a daily basis. It is here that the motion smoother proves to be one of the most important features in everyday use of the television, and this is where the Bravia 3 performs quite well.

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.

Bravia 3 is not equipment for e-sports enthusiasts or fans of night marathons with a controller in hand. The lack of 120 Hz refresh rate and HDMI 2.1 ports closes the topic before it even has a chance to develop. This is a television for casual gamers who will play FIFA or racing games after work, not for someone who measures every frame in a spreadsheet. Nevertheless, Sony has added a few nice extras to ensure it’s not too sparse. ALLM works as it should, automatically switching the television to game mode (low latency). There’s even a simple Game Bar, which is clear. However, the biggest novelty here is the PlayStation Portal app. Thanks to it, you can launch PS5 games wirelessly and view them immediately on the television screen. It sounds great, but just a few minutes is enough to feel significant lag. In our opinion, it’s more of a showcase of capabilities than something that can be used every day. If someone really wants to play, it’s better to connect the console via HDMI cable and forget about wireless issues.

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.
