Philips PUS8209 vs Dreame S100

Unfortunately, this is where the problems start. A maximum brightness of 280 nits is definitely too low to experience the true effect of HDR. In practice, the image resembles standard SDR more, so it's hard to talk about deeper visual experiences. On the plus side, the colour gamut coverage is 91.4% DCI-P3, which will be sufficient for most films. It's also worth noting that the image is stable and there are no issues with sudden brightness or colour changes. Overall, HDR on this television is more of a formality than an actual added value. If we're looking for genuine HDR emotions, this model may not meet expectations.

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 considering the competition in this price range. In full-screen scenes, it's clear that the television can generate an image that hits the mark in terms of 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 the HDR effect – and in a drastic way. In such scenes, the brightness of the bright elements fell below 100 nits, which is a downright tragic result, far from any HDR effect. This aspect can be improved, but there are caveats. You just need to change the local dimming setting in the television's menu; however, then the blacks in such scenes simply turn grey. It's a pity that Dreame wasn't able to refine the local dimming algorithms better, and the S100 is another example that the number of local dimming zones doesn't always translate into a better picture. As a consolation, it's worth noting that the Dreame S100 is marketed as a 'QLED' type television, although it actually uses a PFS LED filter. As a result, the colours are appropriately saturated, and our measured DCI-P3 colour gamut coverage exceeded 94%.

Philips PUS8209 offers many picture modes, but the best of them, without a doubt, is the Filmmaker mode. Despite its proud name, it has its distinct problems. For HD content, the white balance is characterised by a strong dominance of red, causing the image to be significantly warmer than it should be in reality. The brightness characteristic (gamma), although correct in mid-tones, has serious issues at the beginning and end of the graph. Drops in shadows result in a loss of detail in dark areas, and spikes in bright areas make some elements look unnatural.

For high-quality content in 4K HDR, the situation reverses. In this case, blue dominates, leading to an artificial image boost effect, reminiscent of unnatural retail settings. Such an image looks unappealing and does not align with the creators' intentions. An additional problem is the EOTF curve, responsible for brightness in HDR materials. It deviates significantly from the reference graph, causing the image to appear too dark, stripping depth and detail from HDR content.

Against this backdrop, the errors in the Color Checker test and deviations in colour palette reproduction are exceptionally large, which further negatively affects the overall image quality. The Filmmaker mode, while the best among those available, requires substantial corrections to truly convey the full vision of the director.

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 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 - not even a motion smoother. So how do the factory colours fare in the S100? Not too bad, but not great either. The TV itself had a noticeable blue tint, which is clearly evident in our white balance measurements. As a result, the picture was artificially brightened, and the colours had a slight bluish tint. This is also confirmed by the Color Checker palette, which showed how the colour samples leaned towards blue, generating quite significant colour errors. On the other hand, the picture looked definitely better in HDR mode, where the colour errors were not as prominent, although they were still far from ideal. Here, the white balance was also too heavily skewed towards blue, causing quite significant errors in color reproduction.

After calibration, the white balance for HD and 4K content has significantly improved. While we haven't achieved a perfectly flat characteristic, the result is definitely better than before. The image on the television no longer appears either artificially warm or overly cold, which significantly enhances the naturalness of the displayed content. The brightness characteristic (gamma) has also been adjusted – the most significant issues at the beginning and end of the graph have been mitigated. The EOTF curve, which is responsible for brightness in 4K HDR materials, has been stabilised, eliminating problems with excessive dimming of the image. In the colour palette test, some imperfections can still be seen due to the average coverage of the wide colour gamut, which is a limitation of the hardware itself. Nevertheless, the final result is clearly better than pre-calibration – the image looks more natural and approaches the expectations for Filmmaker mode.

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 the advanced white balance correction – both in SDR and HDR content – we completely eliminated excess blue components. The image instantly became much more natural and pleasant to view. After fully tuning the colours, the errors in the Color Checker test dropped below a Delta E value of 2-3. For the average viewer, this means that any colour distortions became almost impossible to see with the naked eye. It's really a nice surprise, as often new brands in the TV market have significant problems with the correct implementation and functioning of sliders in the calibration menu. Here, everything worked as it should. The only thing we need to criticise is the way the TV manages its brightness in HDR. Due to the specific nature of the local dimming algorithms, our measured EOTF curve shows anomalies. In places where high highlights should appear, there is a slight bump in the curve above the reference line. In practice, this results in unnatural brightening of certain, the brightest elements in movies or games. Despite this minor flaw, professional calibration brings a huge, very positive change to this model.

The television offers a “Distortion Reduction” feature that effectively improves the gradation of tonal transitions, particularly when set to the minimum level. Unfortunately, this comes at a cost – the feature also smooths out details like material textures. On the plus side, it’s worth noting that the operation of this option does not negatively affect the film grain, which remains intact.

As for image scaling (upscaling), the television generates a plastic, soft image that generally looks pleasant. However, in the background, issues with aliasing of certain elements, such as branches or small details, can sometimes be noticed, which may decrease the quality of the reception. Despite these minor imperfections, the overall experience of scaling is satisfactory.

For scaling and digital processing in the Dreame S100, the technology used is proudly called Dreamind™ Pro AI by the manufacturer. However, it must be clearly stated that this is not a proprietary processor but rather a marketing term for a chip from MediaTek – specifically, the model MT5889. 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 this chip also handles that. The upscaling in the S100 is fairly average, and the processor has a tendency to artificially over-sharpen edges (fortunately, this can be somewhat tempered with the sharpness slider in the menu). In the options, we also find a feature called "Contour Smoothing," which theoretically is supposed to improve tonal transitions. In practice, it contributes almost no improvement – setting it to any level rarely eliminates visible colour banding, but it can unnecessarily blur elements of the image that should remain sharp.

Another issue is the phenomenon of overscan (cropping the edges of the frame), which is practically visible all the time. Although there is the possibility to set the screen to display the full frame in low-resolution materials, it requires activating the aforementioned Filmmaker mode. And as you may know, this mode completely blocks any changes to other sliders in the picture menu. In our test tables, we noted that the television offers an option to disable overscan, as such a function technically exists in the system – however, in everyday use, while maintaining reasonable picture settings, you will not be able to take advantage of it.

The 60 Hz panel in the Philips PUS8209 is mainly suited for watching movies, but here you can also feel a certain shortcoming. The television does not offer any motion smoothing that would allow you to adjust the fluidity of the picture to individual preferences, which for some users may be disappointing.

When it comes to motion fluidity, the Dreame S100 performs really well. It features a 144 Hz refresh rate panel, although in reality, the vast majority of people using it in a conventional way will still be limited to 120 Hz (as this is what today's hardware allows aside from PCs). Thanks to the high refresh rate, the image in motion remains really sharp, largely due to the well-functioning MEMC motion smoother. In the menu, we find predefined modes that enable the TV to efficiently generate artificial frames, which effectively enhances the fluidity of dynamic sports shots, but also helps eliminate motion judder in film and TV series material recorded at 24 frames.

Philips PUS8209 offers basic features useful for gamers, such as variable refresh rate (VRR), automatic low latency mode (ALLM), and Game Bar, which makes managing settings easier.

Unfortunately, due to the 60 Hz panel, the TV will not meet the expectations of more demanding gamers who are looking for higher fluidity and precision of image. Additionally, this model does not support any HDR mode dedicated to gaming, such as HGiG or Dolby Vision, which further limits its capabilities in this regard.

The Dreame S100 seems almost like the ideal screen for gamers. The television is equipped with 2 HDMI 2.1 ports with a bandwidth of 40 Gbps, allowing features such as automatic game mode (ALLM) or VRR frame synchronization in the range of 48-144 Hz to work seamlessly on consoles. On board, we also find a well-designed gaming panel (Game Bar). It allows you to continuously preview the most important parameters - from the activated picture modes, to the number of frames rendered by the console, right through to the option of adding a crosshair in the centre of the screen. All of this looks great on paper; however, the biggest issue with the S100 is its implementation of HDR in games. The television does not have a correctly implemented HGiG format. This means a clueless user may misconfigure the console during the initial setup of the screen. Poor configuration can result in an image that is too dark or overexposed (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 did not activate at all on the XBOX – Dreame S100 line. And when it was eventually activated, playing was impossible due to the very high input lag often exceeding 100ms. If the manufacturer manages to improve the HDR gaming experience with an update, the S100 will be truly outstanding hardware for gamers. For now, however, compromises must be accepted.
