Philips PML9009 / 9019 / 9059 vs Dreame S100

Philips PML9009 does not really operate at the highest values in HDR content. Most effects with brightness at around 550 nits will not leave us thrilled with the lighting effects, although they are quite stable, which is a plus and will make a considerable difference compared to SDR content. It is worth noting that we can only achieve a good result in one scenario, namely in the film "Gemini", where the flashlight as the only light source can shine. Why in that scene specifically? The answer is quite simple. The scene itself does not contain a large amount of black, and the flashlight is not as large an object as the sun in the first and last scenes. Overall, the brightness measurement results in HDR content do not provide a basis for recommending this television for viewing productions that utilise a wide colour spectrum. Although it is worth noting that this model can cover it to a decent extent of 93% in the case of the DCI-P3 palette.

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 best factory mode used during our tests was "Filmmaker". Here, we will look at both SDR and HDR content. The element that distinguishes them is primarily the EOTF curve in materials with a wide colour gamut and the gamma in those recorded "the old way". Starting with SDR films and series and the most basic thing we can observe, which is white balance, we see a significant dominance of red colour. This led to a yellow tint across the entire image, causing unnaturally looking faces and yellowed whites. This flaw is also evident on the "ColourChecker" palette, where all colours have shifted towards their warmer counterparts. Looking at a more significant graph, that of the gamma responsible for image contrast, we see considerable errors starting from the very beginning. From the left, the value we measured, marked by a connected ellipsis, clearly spiked upwards, causing complete merging of details in the darkest scenes. This state of affairs remained until 10% screen brightness, after which it dipped below the reference orange line, leading to a deterioration in contrast, which, as we know, the Philips PML9009 already lacks. In HDR materials, the white balance issues were very similar to those in SDR content. The discrepancy arises when checking the EOTF curve, which controls the rate of brightness increase and severely limited it, causing the image to appear unnaturally dark. As for the colours themselves, there were more reasons for concern here, as the television's too low luminance caused a huge discrepancy between the actual state and the correct one, which is perfectly visible on the error graph, often exceeding the scale.

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.

Philips PML9009, like most leading manufacturers, has been offering advanced tools for the calibration process for years. Thus, we find 2- and 20-point greyscale adjustment as well as an advanced CMS (Colour Management System). The differences resulting from calibration are evident, and even someone not paying attention to picture quality (although there probably aren't many such here) will notice a positive difference. Both SDR and HDR materials have undergone a significant transformation. The former, as well as the latter, have primarily rid themselves of the unpleasant yellow tint resulting from a red colour dominance in white balance. As for the SDR materials and gamma, although it is not 'lined up' perfectly and still loses dark details, the rest of it is on a more than decent level, and minor errors will not be noticeable. The colours themselves look infinitely better, and thanks to low deltaE errors, they are nearly reference-quality. On the other hand, the HDR materials, due to the low luminance of the unit, were not blended as we would have liked. Although the white balance has been largely normalised, here and there one can notice a slight blue tint. Fortunately, the EOTF curve turned out to be much more accessible and allowed for practically ideal geometry. Unfortunately, due to the screen's insufficient brightness, colour errors are still quite high.

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.

Judging by how PML9009 Philips handled tonal transitions, the image scaling test should perform equally well. This time we are examining the television's algorithms responsible for enhancing the quality of images that have been recorded in lower quality. Such images can be found in various television programmes or older films. In this regard, Philips PML9009 performs quite mediocrely and significantly blurs the image. This is particularly evident in fine branches or the model's hair.

We will take another look at the tonal transitions, which performed remarkably. Within the unit, we find several levels of smoothing. Even the lowest setting can effectively eliminate any non-fluid tonal transition and will work well with the vast majority of content. More importantly, none of the settings for this function softens the effect of film grain, which is extremely important in terms of alignment with the director's vision. However, we note that sometimes it may turn out that fine details will be blurred.

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.

Philips PML9009 is equipped with a panel that has a native refresh rate of 120 Hz. This is the essential minimum for watching all kinds of sports and is recommended for comfortable gaming in favourite titles on consoles or PCs. The manufacturer has prepared an effective system for improving the sharpness of moving images for those who do not like the characteristic stuttering of footage recorded at 24 fps or require a high level of motion fluidity, for example, when watching football matches. In the dedicated tab, we find the "Fluidity" slider, which helps eliminate stuttering, and "Motion Blur Reduction," which aids in increasing the sharpness of dynamic elements. This function works very well and granularly, meaning each setting has a real impact on the perception of motion. With such a set, every user will find their sweet spot. In the picture, we present our choice, which is a slight fluidity enhancement without the soap opera effect.

A matter directly related to motion is the pixel response time of the panel itself. The best in this regard are, of course, OLED panels, followed by IPS and ADS-based units, and finally, VA. Despite the overall good quality of the systems responsible for smoothing the image, the use of a VA panel carries consequences in the form of a black halo behind fast-moving objects. While this will not occur frequently in the tested television, it will be visible here and there.

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.

Philips PML9009, equipped with HDMI 2.1 ports at full bandwidth, supports all features dedicated to gamers. The most basic ones, such as VRR and ALLM, are a given, but G-Sync, FreeSync, and gaming in HDR Dolby Vision with low input lag are not. These features activate without any issues and during the tests conducted, they did not present any problems. Such preparation of the television is certainly a strong point and one can say that it is a unit dedicated to gamers. For more advanced users, we also mention that the PML9009 is equipped with an HGIG mode, which will be particularly felt by gamers, as there are still relatively few games supporting Dolby Vision. This mode primarily allows for the adjustment of HDR effects to the capabilities of the television on a special board, in order to avoid dimming or burning out the image.

The television additionally features a special menu - GameBar. This allows for editing the unit's settings "on the fly", without the need to exit the game. We will also find features such as enabling a crosshair or adjusting black levels for better visibility of opponents in shadows.

In a brief summary of this paragraph, the Philips PML9009 is a unit that will certainly capture the attention of gamers. Thanks to its versatility, it will allow playing any title in the highest quality without compromises. Especially since features such as VRR, ALLM, G-Sync, FreeSync, or gameplay in HDR Dolby Vision will enhance the immersion in the favourite title.

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.
