Philips PML8709 vs Samsung R85H / R86H

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 brightness, the R85H performs quite well. In most of our test scenes the TV reaches around 800–900 nits, and with larger bright elements it can exceed 1000 nits. These aren't, of course, on the level of the most expensive Mini-LEDs, but they're more than enough for watching films and TV series in HDR and the effect can be quite noticeable. The problem reappears in more demanding scenes, where there's a small bright element on a very dark background. Here the TV can greatly reduce its brightness to avoid lighting up too much of the screen. In our measurements such small highlights fell as low as around 200–250 nits, so it's clear that a limited number of local dimming zones combined with the specific behaviour of the algorithm has consequences here. Fortunately, it doesn't affect viewing all the time. In typical, mixed HDR scenes the R85H looks good and can provide good image dynamics. It's just that with very small points of light you shouldn't expect as strong an effect as on TVs with a much larger number of zones or on OLEDs.

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.

In Filmmaker mode our R85H sample in SDR performed adequately, but a few issues immediately stood out in the measurements. In the white balance, as brightness increased more red was added while blue decreased. As a result, the brighter parts of the image had a slightly too-warm tint. Gamma only held the target value at the start. It then gradually fell, which left most of the image a little too bright. The combination of these two factors also affected the colours, with errors growing particularly in the brighter and more saturated samples. It did not look bad, but for Filmmaker mode we expected a bit more accuracy. Interestingly, our sample fared noticeably better in HDR. The white balance was much more even and the individual components stayed close to one another across most of the range. Only in the brightest parts did red start to be lacking, causing white to shift subtly. The EOTF curve looked very good, tracking the target luminance across almost the entire range. That does not mean HDR colours were perfect. The Colour Checker still shows some deviations, especially for some of the more saturated colours, but the errors are clearly smaller than in SDR.

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 calibration the R85H shows it has really substantial colour reproduction capabilities. SDR performed best: white balance could be brought almost perfectly into line, and gamma stays very close to the target value across most of the range. That also translated into very low errors in the ColorChecker, so there's really little to criticise here. HDR also shows a clear improvement, although some issues can't be corrected as well. At the highest brightness levels the character of the backlight itself becomes apparent and the individual components of the white balance begin to diverge. The same applies to the most saturated colours, which don't always land exactly where they should. Despite these limitations the overall picture is considerably more accurate than factory settings, and the biggest difference is definitely visible in SDR. However, there is one thing calibration can't fix. With heavily saturated elements the colour can slightly bleed onto adjacent bright areas of the image. It's easiest to notice on white, which can pick up a faint tint of a neighbouring hue. It doesn't occur in every scene, but when the material is demanding the effect can be visible. This is more a feature of the way the RGB backlight operates than an issue with picture settings.

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.

In the R85H, image processing is handled by the Micro RGB AI Processor. The name is new, but when it comes to upscaling lower-quality sources, the TV's behaviour is very similar to what Samsung has shown before. And that's not a bad thing, because Samsung has handled this aspect quite well for years. Lower-resolution material is displayed cleanly, edges don't become overly soft, and the TV doesn't try to artificially extract detail at all costs. The result is simply balanced, and for regular TV or older recordings the R85H performs as you'd expect from Samsung at this level. There's still a small downside: overscan, which can't be completely switched off at the lowest resolutions. Another matter is the extra processing applied to low-quality sources. The R85H can smooth posterization and tidy up heavily compressed footage, but it's worth emphasising that it does so relatively aggressively. At stronger noise reduction settings it starts removing not only compression artefacts but also fine detail and the natural film grain. So it's best to use it only when the source actually needs it.

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.

R85H has a 144 Hz panel, so motion handling is really good here. You should remember that the extra hertz above 120 will mainly be used when connected to a computer, so in this category we don't treat them as any particular advantage. For films and TV, what's more important is that the panel is fast enough to provide access to an advanced motion smoothing feature, "Motion Clarity", which lets us set motion from more film-like to very smooth. The panel's response time is a bit worse. Since it's a VA panel, fast-moving objects can leave a slight trail. On a bright background this isn't very noticeable, but the darker the scene, the more noticeable the smearing becomes. This is a typical characteristic of this type of panel and it's easiest to spot in dark scenes.

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 has been steadily expanding its gamer features for several years, and the R85H really doesn't lack anything important. The TV supports 4K at 120 Hz, VRR and ALLM, so it can easily make full use of the PlayStation 5 or Xbox Series X. HGiG also works properly, so when HDR is set correctly on the console, games maintain their intended brightness and you don't unnecessarily lose detail in the brightest parts of the image. The only bigger omission is Dolby Vision Gaming, which Samsung doesn't support on any of its TVs.

The Game Bar is also very useful, a handy menu you can bring up without leaving the game. You can quickly check the frame rate, VRR status or change the key picture settings. Samsung also includes a few less obvious features, like the ability to change the aspect ratio or Game Motion Plus, which can further smooth games running at 30 or 60 fps. Of course this comes at the cost of higher input lag (around 55 ms), but for slower-paced titles it may be an interesting option for some.
