Philips PML8709 vs Samsung OLED S95H (S99H) (QD-OLED)

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.

When it comes to pure brightness, the S99H is an astronomically bright TV. Its peak brightness in film scenes can exceed 2,800 nits. Whatever the scene, you can expect powerful HDR effects that are almost blinding, which is exactly what we want from a top‑tier display. By nature, an OLED panel can't maintain that extreme brightness in very bright, full‑screen frames the way it can with small bright highlights, but the results are still excellent. In a bright scene from The Meg the sun still exceeded 2,200 nits. That means the S99H was able to hold a higher brightness than most Mini LED screens on the market. In terms of brightness the S99H is currently the best OLED TV we've tested.

Colour gamut coverage

The S99H also handles colours exceptionally well, thanks directly to the QD‑OLED panel used here. Whether the test used synthetic test patterns or measurements with film material in the background, the results remained very high. The S99H easily covers almost 100% of the DCI‑P3 gamut, and in the most demanding space, BT.2020 it reaches nearly 90%. That's absolute top‑tier performance. These results match what we saw in the new SQD‑Mini‑LED displays, and in real film scenes they even surpass RGB Mini LED displays.

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.

Samsung offers a whole host of picture modes and features, but we traditionally recommend choosing FILMMAKER mode, especially if you want the most faithful rendering of the creators' intent. Out of the box the TV is tuned very well, though it has minor flaws. These are mainly a slight deviation in white balance in SDR content and a slightly low gamma. As a result, the picture in a dark room can be a little too bright compared with the reference value of 2.4, which is the standard for watching films with the lights off. These are, of course, small issues, because overall colour reproduction remains very good and the errors in ColorChecker measurements are not large. However, we know that for a screen of the S99H's calibre you can and should expect even more, so we subjected it to professional calibration.

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.

After professional calibration, FILMMAKER mode looks practically perfect. Because Samsung offers a rich set of advanced calibration controls, we were able to tune the colours to an almost perfect level. Above all, we managed to even out the white balance and the gamma curve, which resulted in noticeably improved contrast and correct image modelling. In a profile prepared like this there really isn't a single thing to pick apart or call a fault. After calibration, the S99H can deliver an essentially reference-quality picture.

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.

Upscaling and digital image processing are handled by Samsung's proprietary NQ4 Gen3 processor. It copes very well with scaling lower-resolution content to 4K. The picture is clear without looking artificial or overly sharp. The only fairly specific drawback appears with very old material recorded at 480p or lower. In such cases the TV can slightly crop the edges of the image.

The processor also does a decent job with artefacts visible in low-bitrate material, for example in heavily compressed YouTube videos. The noise reduction function effectively smooths the picture and reduces posterisation, but it works quite aggressively. It can remove not only unwanted artefacts but also some fine detail, and even natural film grain. We, wanting to preserve maximum fidelity to the source material, chose not to use it. However, if someone values a clean, as-smooth-as-possible image more than keeping every detail, it may prove useful.

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.

Another major advantage of organic panels is very good motion handling. Thanks to the pixels' near-instant response time, the Samsung S99H shows virtually no smearing. Fast-moving objects don't produce visible halos or trailing artefacts, so the TV performs very well for both sport and gaming. One quirk of OLED screens compared with LCD is the way they render low-frame-rate material. With very slow camera movement the picture can appear noticeably more juddery. This can be quite effectively mitigated using frame interpolation. Samsung lets you adjust judder reduction and motion blur reduction separately, so it's easy to find a compromise between a smoother picture and preserving the cinematic feel of the content.

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.

Samsung S99H is also a top TV for gamers. It offers almost every possible and useful feature... well, perhaps except the obvious lack of Dolby Vision for the Xbox console. It’s equipped with four full-fledged HDMI 2.1 ports with the full 48 Gbps bandwidth. That makes it easy to use frame-rate synchronization VRR or automatic low-latency mode (ALLM). This year Samsung also has no issues with proper HGiG support, so HDR setup on a console is quick and free of unnecessary complications. Samsung is also known for interesting extras in its TVs. In the Game Bar menu you’ll find options to add an on-screen crosshair, enlarge the minimap, or change the aspect ratio of the displayed image (PC).

Particularly noteworthy is Samsung’s feature: Game Motion Plus. It’s Samsung’s proprietary motion-smoothing system that uses interpolation to boost smoothness in games. Input lag then rises to around 40 to 50 ms (depending on the strength of the setting), which, compared with the competition, is an excellent result. The system makes gameplay noticeably smoother. So if someone has their eye on a demanding game (e.g. GTA 6 😉) that runs on a console at only 30 fps, the S99H can display it much more smoothly than competing models.
