Samsung QD-OLED S90D / S94D vs Philips PML9009 / 9019 / 9059

In the HDR effect category, the Samsung S90D delivers remarkable performance. On the luminance graph for up to 10% of the window, the television surpasses the 1000 nits mark, which is a notable achievement. However, in the film scenes we tested, these values were slightly lower. In scenes with fullscreen sun glare the brightness drops to about 500 nits, but this is still considered a very good result. It is also worth noting that this model stands out due to its very high colour gamut coverage, thanks to the QD-OLED panel, giving it an edge over televisions with WOLED panels, which cannot achieve such a wide spectrum of colours.

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 Samsung 65" S90D with a QD-OLED panel has been tested in Filmmaker Mode, which the manufacturer has used for years to deliver optimal picture settings. In this mode, the TV offers a very good image, but there are some shortcomings worth noting.

In terms of white balance, viewers may notice a red dominance in HD content, which can make skin tones appear unnatural and create a warm overall scene, potentially affecting immersion. This issue becomes more apparent in scenes where subtle colour differences are important. The same effect can be observed in 4K HDR content, though the red shift is less pronounced. This shift can prevent certain details and colours from being fully realised, diminishing the naturalness of the image.

As for contrast, the gamma performance is decent but still has some issues. The gamma values fall short of the reference level of 2.4, resulting in bright areas of the image appearing washed out and dark areas lacking detail. This limitation can make certain scenes feel less dynamic and impact the depth and richness of the picture. However, the EOTF curve for contrast in 4K HDR content performs well, showing the TV's ability to handle differences in brightness. That said, these values still fall slightly below the ideal range, indicating room for further optimisation.

Overall, the Samsung S90D in Filmmaker Mode offers solid colour reproduction, but some adjustments are needed to fully unlock its potential, particularly with different types of content.

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.

The quality improves more than anticipated after calibrating the S90D television in movie mode. The white balance for HD and 4K HDR content has been fine-tuned to near perfection. While minor imperfections are still noticeable, they are subtle enough not to significantly impact the overall picture quality. Colours have become more cohesive, promoting a natural reproduction of details, particularly in scenes where precise colour representation is essential. It’s important to note that this particular model, in this size, uses a QD-OLED panel, which offers a broader colour gamut compared to other versions of this model equipped with a WOLED panel.

The contrast has also seen a marked improvement. After calibration, the gamma chart is much closer to the expected curve, resulting in a better balance between the bright and dark areas of the image. The EOTF curve, which previously indicated issues with overexposed scenes, now shows significantly better results. This improvement allows for greater preservation of details in the brighter parts of the image, particularly in HDR content.

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 television excels at smoothing tonal transitions, allowing colours to blend seamlessly, resulting in a natural and fluid image. The built-in noise reduction feature can further enhance these transitions, useful in certain situations. However, it is important to note that activating this option may overly smooth out the desired film grain structure, potentially compromising the authenticity and atmosphere of the image. Therefore, caution is advised when using this feature, to maintain the character and depth of the content.

The S90D model handles lower-resolution materials effectively, as demonstrated in the displayed image. The model's silhouette remains sharp and naturally reproduced, with fine details preserved. Additionally, the branches of the trees are well-defined, free from any visible jagged edges that might otherwise degrade the image quality. Thanks to efficient scaling, even lower-resolution content appears attractive on the screen, which is sure to please users who rely on a variety of content sources, such as standard cable or antenna television.

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.

The S90D TV, featuring a 120 Hz refresh rate matrix and up to 144 Hz in the appropriate PC configuration, delivers excellent motion fluidity. Samsung highlights a range of sharpness settings on a ten-point scale, allowing users to fine-tune the display to their preferences. In UFO tests, the OLED matrix showcases its strengths by eliminating any blurring. The ultra-fast pixel response ensures dynamic movements are faithfully reproduced.

Similar results can be seen in other sizes of this model with a WOLED matrix, which also offer outstanding image fluidity. Organic technology, in this case, is considered among the best on the market. The S90D image, regardless of the matrix type, is exceptionally sharp and detailed, making this television perfect for dynamic scenes, whether for gaming or sports broadcasts. Additionally, its refresh rate and sharpness capabilities guarantee that every movement is smooth and natural, satisfying even the most discerning users.

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.

The S90D television is an excellent solution for gamers, offering a range of advanced features that elevate gaming quality to a new level. Equipped with HDMI 2.1 standard, the model supports modern technologies such as VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). Thanks to these solutions, the image is incredibly smooth, and the response to commands is instantaneous, which is crucial in dynamic titles. Additionally, the S90D supports HLG (Hybrid Log-Gamma) as well as G-Sync and FreeSync image synchronisation. This enables a perfect connection with Xbox, PlayStation, or PC, eliminating issues with tearing and stuttering. The built-in operating system offers the Xbox Game Pass app, providing access to a vast library of games directly from the television. This solution makes gaming even more convenient and accessible. The Game Bar feature provides quick access to essential information, such as current settings, performance statistics, and the ability to adjust image options. This allows for on-the-fly display parameter modification, which is extremely useful during intense gameplay. Despite lacking support for Dolby Vision, the S90D still offers excellent HDR image quality, allowing for full utilization of the potential of games and movies. As a result, the S90D represents a unique combination of modern technologies, outstanding image quality, and intuitive features, perfect for any gaming enthusiast.

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.
