Philips PML8709 vs Panasonic W85

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 hard to explain. The maximum brightness we were able to achieve was only 350 nits, which is definitely too low to fully enjoy HDR effects. In practice, the TV barely stands out against an average SDR. The situation becomes even more surprising in the case of test scenes, such as the second one from the movie Life of Pi or Sicario 2. Small light elements reach only 120 nits there, making them practically invisible. Such a level of brightness is completely inadequate to modern HDR standards and significantly diminishes the viewing experience of high-quality content. The only bright spot in this category is the very good coverage of wide color gamuts – 97% DCI-P3 and 83% BT.2020. This ensures that colors are saturated and well reproduced, which can improve the overall viewing experience of HDR materials, even if just a little. However, the lack of appropriate brightness means that even this cannot save the Philips PML8709 in this category.

Unfortunately, we don't have good news here. The Panasonic W85B is rather dim – its peak brightness does not exceed 300 nits, so it's hard to talk about any true HDR effect. In practice, this means that scenes which on other screens can "shine" and make an impression, here look simply like regular SDR with a slight boost in colors. Our measurements and film tests confirmed this – regardless of the content, the W85B won't extract anything more from HDR. So if someone is looking for a TV specifically for HDR, it's better to look towards other models. As a consolation, the fact remains that in terms of colors, the W85B performs quite well. It's a QLED TV, so its color gamut coverage is wide, and most films and series look natural, without a distinct "washed out" effect. The colors are saturated, so during regular viewing, there is no sense that something is quite wrong.

Although theoretically the Filmmaker mode on the Philips PML8709 should provide natural color 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 makes the image appear washed out and cold, which is particularly noticeable in the comparison picture below.

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

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

While testing the Panasonic W85B, we of course started with the Filmmaker mode, as it is the gold standard today for watching content "as the director intended." The problem is that this TV is quite far from those intentions. The biggest issue turned out to be an excess of red – in both SDR and HDR. The picture often looked overly warm, and in some scenes, it appeared almost "blazing." Additionally, there’s the issue of brightness management. When we looked at the gamma and EOTF charts, it was clear as day that in most scenes, the TV brightens the image more than it should. The effect was easy to predict. Details can get lost, leading to flattening and clipping across the entire screen. Of course, we know how to improve this, but it must be said honestly that it requires quite a bit of work in calibration. Out of the box, the W85B does not provide a reference-level picture – it is rather a TV that will always interpret colors and brightness a bit "its own way" without professional adjustments. Unfortunately, this is to the detriment of the viewer.

Philips offers advanced image calibration tools in its televisions, which we decided to fully utilize. The effects? While we managed to improve many aspects, it was not without difficulties. White balance was one of the biggest challenges – despite our efforts, it can be called a battle against windmills. We managed to correct it significantly, making the image look much better than in the factory settings, but it is still far from perfect. Particularly in some scenes, a subtle dominance of blue is noticeable, though not as intense as before. We achieved significant improvement in brightness characteristics – gamma now presents itself much more stably. The EOTF curve looks correct at first glance; however, when analyzing film content, it becomes evident that the television has difficulty maintaining the appropriate characteristics. The algorithms "struggle" to adjust brightness, which may result from the limited number of dimming zones that do not always cope with more complex scenes. Overall, the image after calibration looks much more pleasant to the eye – colors are more natural, and errors in color reproduction have been minimized. Although it's still not perfect, the Philips PML8709 now presents itself much better than in the factory settings.

Fortunately, calibration made a significant difference for the Panasonic W85B, especially in SDR content. Here, the improvement was really noticeable – we managed to balance the white and reasonably tame the TV's tendency to excessively brighten the entire image. The picture became more coherent, and the colors gained a naturalness that was lacking in the factory settings. Admittedly, the results from the Color Checker are not perfect, as the W85B has visible issues with green saturation, but overall, we assess the post-calibration effect in SDR very positively. The situation with HDR is a bit different. Here, we were also able to limit the tendency to warm up the entire scene, so the image turned out much better than in the factory settings. However, the same problem we mentioned earlier is still evident – the TV interprets the image too "in its own way" and brightens the entire frame. The lack of local dimming only exacerbates this effect. In summary, briefly in SDR content, the W85B performs really well after calibration and is perfectly suitable for everyday viewing. However, in HDR, even after adjustments, it is still hard to unequivocally recommend it for serious viewing sessions.

The distortion reduction function 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 some tonal transitions may still appear slightly uneven. An additional drawback is that this function also smooths other details, such as material textures like shirts, which can affect image sharpness.

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

With native SDR content, the Panasonic W85B performs very well – tonal transitions are smooth and natural, without artificial bands or clear contours. However, the situation looks worse with lower resolution materials. This is where the television has the biggest problem with "beautifying" the image. The lack of any option in the menu that would allow for improving gradation means that with older films or materials from YouTube, one can sometimes notice slight issues with color blending.

Fortunately, upscaling, or increasing the quality of lower resolution content, performs much better. This is definitely a strong point of this model – the image is scaled cleanly and in detail, and the television handles this better than one might expect from such an affordable device. This is thanks to the HCX processor, which Panasonic has been developing for years, and it shows that even in the lower series, it can do a good job.

Philips PML8709 is one of the few models with mini-LED technology on the market that offers a refresh rate of 60 Hz. Although it is not a panel for the most demanding gamers, it should satisfy those who mainly watch movies. The television is equipped with the "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" appearance to a cinematic aesthetic with clearly visible frames.

At first glance, everything looks good – the Panasonic W85B has a 120 Hz panel and even a 144 Hz mode, so it seems that it should handle smooth motion well. The problem begins when we look into the settings. The options for improving fluidity are supposedly present in the menu, but in practice… they change nothing. No matter what we choose, the image looks the same. On top of that, there's a lack of BFI, which is the black frame insertion mode that helps sharpen motion in many TVs. And suddenly, it turns out that despite having a strong panel, the W85B doesn't give us any real tools to adjust that motion to our needs. It only works well when the source itself operates at a higher frequency – for example, games at 120 Hz. But when it comes to movies or sports, we just have to take what the TV shows us, because there's nothing more we can do about it.

Philips PML8709 is a television aimed more at occasional gamers, mainly due to its 60 Hz panel, which does not meet the expectations of the most demanding users. However, for those who appreciate gameplay at a more measured 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 displaying images more smoothly without annoying stutters. Moreover, in terms of HDR, we find here the implementation of HGiG, which adjusts the HDR effect to the specifics of games, providing a more natural image in appropriately optimized titles. Unfortunately, there is no support for Dolby Vision mode, which may be felt in games that utilize this format.

A nice addition is the presence of a basic "Game Bar," which allows for quick preview and modification of key settings related to gaming. It's a simple yet helpful feature, especially for those who often change their setup between different types of gameplay. Despite certain limitations, the Philips PML8709 offers a solid set of features for less demanding gamers.

On paper, the Panasonic W85B looks really solid. Here we have two full HDMI 2.1 ports, support for ALLM, variable refresh rate, Dolby Vision in games, and of course, a high refresh rate for the panel itself. Additionally, there’s the characteristic Panasonic game bar that allows you to check key parameters with one click and quickly change them if necessary. Sounds great, but the problem arises when we activate HDR. Here, the W85B significantly falters because it lacks proper HGiG implementation – the TV manages brightness poorly, and instead of faithful image rendering, we get scenes that are too bright, sometimes even blown out. The solution? The simplest – turn off HDR in the console settings and leave everything in SDR. And here it gets really interesting, because in this scenario, the W85B shows its better side. Low input lag, high smoothness thanks to 120 Hz – all of this makes gaming look phenomenal. Yes, HDR can be sacrificed, but if responsiveness and smooth gameplay are priorities, the W85B provides a lot of fun.
