PHILIPS PUS9010 (IPS) vs Dreame S100

In the Philips PUS9010 version with an IPS panel, the HDR brightness sadly performs worse than in the previously tested 55-inch variant with a VA panel. The difference reaches about 100 nits, which is noticeably significant given the relatively low values. While the VA version could exceed 500 nits, here the maximum brightness reaches around 400 nits. This level still allows for watching movies and series in HDR, especially on streaming platforms, but the effects are clearly more subdued. Bright elements don't have the same impact, and scenes requiring high luminance are less impressive. On the plus side, the coverage of the DCI-P3 colour gamut is commendable. The IPS version offers about 91%, which is roughly 5% more than the variant with a VA panel. This translates into slightly better colour saturation in HDR content, despite the lower brightness. Colours can appear more vivid and cohesive, especially in colourful scenes.

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%.

We evaluated colour reproduction, as always, on factory settings, focusing on the movie mode, which in the case of Philips usually offers the best starting point. This is also a good moment to show how much the same model of TV can vary depending on the panel used. Looking at the white balance, the overall tendency remains similar to the version with the VA panel. There is still excessive red in the whites, however, in the tested unit with the IPS panel, there are also losses in the blue channel. As a result, the picture has a slightly different colour character, which is well illustrated in the comparative materials. This is a very good example showing why ready-made settings downloaded from the internet do not always work even within the same model.

However, returning to the assessment itself, this unit performs quite well, especially in SDR content. Colour tests show correct saturation and colour consistency, without glaring errors that could hinder everyday viewing. In HDR materials, it is possible to notice slight losses in reds, but these are not flaws that completely spoil the image perception. The biggest limitations do not stem directly from the colours, but rather from the whites and blacks. The use of an IPS panel and slightly lowered gamma means that the image is slightly boosted in brightness, and weak blacks further affect perceived contrast. This makes everything look brighter, but at the same time, it lacks depth, especially during evening viewing.

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 picture has been brought to a really reasonable level. The whole thing looks cohesive and natural, and when it comes to colour reproduction, it's hard to definitively say whether we're dealing with a VA or IPS panel. This is a good sign, showing that the television has a solid foundation for further adjustments. The larger colour gamut in this variant is a plus, as it can subtly enhance the depiction of colourful scenes, especially in HDR content. However, this advantage is largely offset by the boosted blacks resulting from the use of an IPS panel. The limited depth of black affects perceived contrast, particularly when watching in a dark room. As a result, despite noticeable improvement post-calibration, the final rating remains the same as that of the variant with a VA panel. Better colours are not able to fully compensate for the weaker blacks.

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.

In the Philips PUS9010, we find another iteration of the P5 Perfect Picture image processor, which aims to improve the quality of lower-grade materials. One of the components of this system is a distortion reduction function that smooths tonal transitions. It works effectively and actually reduces visible banding. Unfortunately, it does so quite aggressively. In practice, it can mute details such as material textures or film grain. This is a clear compromise, so we wouldn't particularly recommend it for movie sessions. For more casual content, like YouTube or regular television, it performs much better. The P5 processor also handles lower resolution materials quite well. The image is soft, at times even too soft, but it can easily be corrected using the sharpness slider, adjusting the effect to personal preferences. A positive aspect is also the absence of edge cropping in SD materials, which is still not standard in this class of televisions.

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.

Philips PUS9010 has a 4K panel with a refresh rate of 144 Hz, which will be appreciated mainly by sports fans and gamers. This is especially noticeable in dynamic scenes where the motion is sharp, and annoying blur is almost non-existent. When it comes to movies (standard 24 fps), Philips offers us a proven set of settings known from its higher series. Two sliders are used to control motion. “Smoothness” allows you to adjust the picture to your liking: at low settings, it maintains a cinematic character, while moving the slider to the right gives us a perfectly smooth, albeit slightly “theatrical” effect. Meanwhile, “Motion Blur Reduction” is a feature designed for sports – it ensures that fast-moving objects do not lose detail and remain clear.

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 PUS9010 is a solid machine for gaming. It has everything that’s important: VRR, automatic game mode (ALLM), and support for HGiG. The latter is fantastic – it allows you to set HDR in games exactly the way the developers envisioned. The TV handles 120 Hz refresh rates effortlessly at every popular resolution (1080p, 1440p, and 4K). It doesn’t matter if you connect a PS5, Xbox, or a powerful PC – everything runs smoothly and just as it should. Gamers will also appreciate the Game Bar. It’s a quick, clear menu where you can immediately see if the low latency mode is active. This is especially useful when frequently switching between different consoles. The whole experience is enhanced by Ambilight. Evening sessions with this backlighting create a whole different level of atmosphere; the image seems larger, and dynamic scenes are even more impressive. Even if someone isn’t a fan of such “gimmicks,” it’s hard to deny that it makes an impression.

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.
