Samsung OLED S90D / S94D (WRGB OLED) vs Philips PML8709

In the tested film scenes, the Samsung S90D television achieves impressive brightness results, exceeding the 1000 nit barrier in the first four shots, which can be considered a remarkable outcome. In the case of the last shot, where a full-screen flash of sunlight is visible, the brightness drops to around 500 nit, but it still remains at a very good level. Additionally, the television impresses with a DCI-P3 colour space coverage value of 98%, which guarantees extraordinarily rich and realistic colour reproduction, further enhancing the image quality. This result makes the Samsung S90D an ideal choice for those expecting high-quality images in a variety of lighting conditions.

Looking at the contrast results, we expected that the algorithms responsible for the zones in the Philips PML8709 would be at least decent. However, what we encountered during testing is difficult to explain. The average brightness we managed to achieve was just 350 nits, which is definitely too low to fully enjoy HDR effects. In practice, the TV barely stands out compared to an average SDR. The situation becomes even more surprising in test scenes, such as the second one from the movie Life of Pi or Sicario 2. Small light elements achieve just 120 nits there, making them practically imperceptible. Such a level of brightness is completely below modern HDR standards and significantly diminishes the experience of watching high-quality content. The only bright spot in this category is the very good coverage of wide color gamuts – DCI-P3 at 97% and BT.2020 at 83%. This ensures that colors are saturated and well-reproduced, which can somewhat improve the overall experience of watching HDR materials. However, the lack of adequate brightness means that even this cannot save the Philips PML8709 in this category.

The S90D television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more discerning users. This mode may seem too warm, and users who have switched from Standard mode might experience a slight shock. It’s worth noting that this state of affairs is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue, causing colours to appear warmer than they should. In practice, this means that certain shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma chart indicates slight fluctuations, which may result in the image being minimally darker, especially in the shadows. This can affect the clarity of details in darker scenes. Meanwhile, in 4K HDR materials, the EOTF curve is located above the recommended line, leading to some parts of the image being displayed too brightly, which can cause clipping in the brightest areas. Overall, Samsung S90D delivers a solid picture straight out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

Though theoretically the Filmmaker mode in the Philips PML8709 should provide natural colour reproduction, in reality it resembles a store mode more. In the white balance, both for HD and 4K content, there is a clear dominance of blue. This causes the image to appear washed out and cold, which is particularly noticeable in the comparative image below.

The brightness characteristics also leave much to be desired. Both gamma and the EOTF curve exhibit excessive screen brightness. As a result, there is a loss of detail in both the brighter and darker areas of the image, further diminishing its credibility and naturalness. Bright elements appear unnaturally flat and little varied.

These significant issues with white balance and brightness characteristics lead to noticeable errors in colour reproduction, which can easily be seen in films as well as the Colour Checker test. The colours are inaccurate, affecting the overall image quality and visual experience. The factory settings require significant improvement in order to fully enjoy the potential of this television.

After calibration, the Samsung S90D TV in movie mode looks even better than one might expect. The white balance for both HD and 4K HDR content has been improved almost to perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the picture quality. Colours are more balanced, leading to a natural reproduction of details, especially in scenes that require a precise colour palette. It is worth noting that this model in this size is equipped with a WOLED panel, which has less coverage of a wide colour gamut and does not offer as rich colours as, for example, the 65-inch version, which is equipped with a QD-OLED panel.

The contrast has also seen a significant improvement. The gamma graph after calibration is much closer to the expected line, providing a better balance between bright and dark areas of the image. The EOTF curve, which showed problems with overexposed scenes before calibration, now demonstrates better results. This effect allows for greater detail to be preserved in the bright parts of the image, especially in HDR materials.

Philips offers advanced image calibration tools in its televisions, which we decided to fully utilise. The results? Although we managed to improve many aspects, it wasn't without difficulties. White balance was one of the biggest challenges – despite our efforts, it could be called fighting against windmills. We were able to significantly correct it, so the picture now looks much better than in the factory settings, but it is still far from perfect. Especially in some scenes, a subtle dominance of blue is visible, although not as intense as before. We achieved a significant improvement in brightness characteristics – gamma now appears much more stable. The EOTF curve looks correct at first glance, however, when analysing movie content, it is evident that the television has trouble maintaining the proper characteristics. The algorithms are "struggling", trying to adjust brightness, which may be due to the limited number of dimming zones that do not always handle more complex scenes well. Overall, the picture after calibration looks much more pleasing to the eye – colors are more natural, and colour reproduction errors have been minimised. Although it is still not perfect, the Philips PML8709 now presents itself much better than in the factory settings.

Television S90D handles tonal transitions very well. Thanks to the technology used, transitions between colours are smoother and more natural. You can also use the noise reduction feature, which further smooths out tonal transitions, which can be useful in certain situations. However, it's worth remembering that turning on noise reduction can also lead to the smoothing out of desirable film grain, thereby reducing the cinematic feel of the image. For this reason, caution is advised when using this feature, as it’s better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint and excels in scaling images from lower resolutions. The S90D Samsung TV effectively processes lower resolutions, as seen in the visible image. The outline of the model is clear and accurate and, as a result, looks natural and detailed. Moreover, the branches of the trees are well-represented, showing no significant jaggedness that could degrade image quality. With effective scaling, even materials in lower resolution present attractively on the screen, satisfying users who prefer various sources of content such as regular antenna/cable television.

The distortion reduction feature in the Philips PML8709 smooths tonal transitions, but its effectiveness leaves much to be desired. We recommend setting this option to "Medium" - at this level, the effect is noticeable but not excessive. Unfortunately, compared to other Philips models, the smoothing effect is less effective, meaning that certain tonal transitions may still appear somewhat uneven. An additional drawback is that this feature also smooths other details, such as the textures of materials like shirts, which can affect image sharpness.

As for image scaling, the television performs very well. The image appears smooth and free of noticeable "jaggies". This effect may appeal to many users, although some might prefer a more vivid look. Fortunately, the television allows for adjustment of the sharpness parameter, enabling us to tailor the image to individual preferences.

Samsung S90D TV is equipped with a 120 Hz panel, with the ability to overclock to 144 Hz with the right PC configuration, providing exceptional motion smoothness. For years, Samsung has offered a variety of ten-point settings for image clarity, allowing users to adjust the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there is no sign of any motion blur. The pixel response is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The image is incredibly sharp and detailed, even during fast action, making the S90D an ideal choice for gamers and sports enthusiasts.

Philips PML8709 is one of the few models with mini-LED technology on the market, offering a refresh rate of 60 Hz. While it’s not a panel for the most demanding gamers, it should satisfy those who mainly watch movies. The TV is equipped with a “Motion Style” feature, which is a motion smoother that allows you to adjust the fluidity of motion according to your preferences – from a more “plastic” look to a cinematic aesthetic with clearly visible frames.

The Samsung S90D television is perfectly adapted to the needs of gamers, offering four HDMI 2.1 ports that support key features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). With these technologies, gamers can enjoy smoother and more responsive gameplay, significantly enhancing comfort and performance during intense gaming sessions. An additional advantage of the television is the special Game Bar, which allows for easy management of game settings. This functionality enables quick adjustments of parameters, such as changing the aspect ratio of the television screen, which can be useful in various games and types of gameplay. Users can easily customise their preferences, making the use of the television while gaming even more convenient and enjoyable. As for PC users, the television pleasantly surprises. When connecting a computer, the panel is able to achieve a refresh rate of 144Hz, and users of Nvidia or AMD graphics cards can enjoy features such as G-Sync and FreeSync. However, it should be noted that the television does not support Dolby Vision, which may be a downside – although it is worth considering that Dolby Vision is not as popular in the context of games as it is in films. Nevertheless, the S90D television still offers excellent features for gamers, making it a great choice for gaming enthusiasts looking for outstanding picture quality and modern technological solutions.

Philips PML8709 is a television aimed more at casual gamers, mainly due to the 60 Hz panel, which won’t meet the expectations of the most demanding users. However, for those who appreciate gaming at a more moderate pace, this model may prove sufficient.

The television offers several gamer-friendly features, such as ALLM (automatic switching to game mode) and VRR (variable refresh rate), which help in providing smoother image display without annoying stutters. Furthermore, in terms of HDR, we find the implementation of HGiG, which adjusts the HDR effect to the specifics of games, ensuring a more natural image in appropriately optimised titles. Unfortunately, there is no support for Dolby Vision mode, which may be noticeable in games that utilise this format.

A nice addition is the presence of a basic "Game Bar," which allows for quick previewing and modification of the most important settings related to gaming. It’s a simple but useful touch, especially for those who frequently change their configuration between different types of gameplay. Despite some limitations, the Philips PML8709 offers a solid set of features for less demanding gamers.
