Philips PML8709 vs Samsung Q7F

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.

Unfortunately, the Samsung Q7F is not one of the bright televisions, which directly impacts the quality of HDR films. The peak brightness of the panel is only around 250 nits, which is definitely insufficient for claiming a true cinematic experience. In practice, the HDR content does not differ significantly from classic SDR, making it difficult to talk about any "wow effect" that usually accompanies us when watching such films. During testing of film scenes, the image simply looked dark, and the brightness almost always hovered around the aforementioned 250 nits. The worst performance came from shots with small, intensely glowing elements – the global dimming technique used reacted very aggressively in those cases, dimming the entire screen to maintain the black effect. However, it is worth noting the presence of a QLED coating that broadens the colour spectrum. For a budget QLED model, the Q7F performs quite decently here: the DCI-P3 colour gamut coverage is around 93%, and BT.2020 reaches 70%. This means that despite the low brightness, the colours can still look quite vivid and attractive.

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.

The reproduction of factory colours in the Samsung Q7F is definitely not one of its strong points. In Filmmaker mode, which theoretically should be closest to neutral, the white balance issue is immediately noticeable. There’s too much red on the screen, while blue is lacking. The effects are very easy to notice – white, instead of being neutral, takes on warm, almost slightly orange tones. In the long run, this makes the entire image appear a bit unnatural, while bright areas of the scene can seem unrealistic. The problems are even more evident in HDR content. The charts show that the TV has significant errors in the Color Checker palette, which results in visible inaccuracies in the real image. In practice, this means that colours are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, causing them to lose their cinematic feel, while bright parts can be dimmed. This makes the image seem flattened, and contrast, instead of helping to bring out details, only highlights its own limitations. In HDR materials, this is particularly frustrating because every detail matters. In scenes where a subtle play of light and shadow should be felt, the Q7F either overdoes the lighting or, conversely, suppresses elements that should attract the eye. This causes the image to lose its depth, and instead of cinematic realism, we have a rather simplified effect.

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, we managed to bring the Q7F to order – at least in terms of SDR content. The image in this mode looks really good: the white balance has been set correctly, the colours appear natural, and the errors in the colour palette have dropped to levels practically invisible to the eye. Gamma behaves exemplary, and the only minor flaw remains a slight lightening of smaller elements, which stems from the lack of local dimming. For everyday watching of television or films in standard quality, the Q7F performs surprisingly well.

It was significantly more challenging to tame HDR content. Despite adjusting the white balance, the television still heavily manipulates brightness, causing scenes to appear unnatural – what was meant to be subtly darker can sometimes be overly bright, and the bright parts of the image can occasionally be dimmed. The final effect is better than in factory settings, but it’s clear that the construction limitations of the Q7F do not allow for fully utilising the potential of HDR materials.

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 in the Q7F is a bit of a rollercoaster. On one hand, we have really nice upscaling – weaker sources look better than you might expect. The image becomes clearer, sharper, and even older films or free-to-air TV hold up well. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… things start to get tricky. The TV has a problem with overscan – part of the image is simply cut off, and it doesn't look very elegant. Additionally, we were let down by a feature called "noise reduction," which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it practically makes no difference – the banding in gradients is still there. It's a bit of a shame because we expected more from a model that is aimed at users looking for a display for SDR content.

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.

Motion blur and motion fluidity in the Q7F is probably the most budget-friendly aspect of this television. The 60 Hz panel makes the motion blur quite noticeable, especially in dynamic scenes, and it's rather hard to consider this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, there was a long trail, similarly, the ball in a football match would leave behind streaks.

On the positive side, the presence of motion smoothing is worth noting. In films, it really makes a difference – especially since most materials are recorded in 24 frames. Here we can decide whether we prefer a more "cinematic" image, with a slight judder typically found in cinema, or a smoother, more “TV-like” one. This actually works quite well and helps improve the viewing comfort for series or movies.

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.

The features for gamers on the Samsung Q7F is a topic that stirs up quite a few mixed emotions. On one hand – no reasonable person was expecting miracles here, after all, it’s a 60 Hz television and it was clear from the get-go that this wouldn’t be equipment to squeeze the maximum from a console or PC. On the other hand, since the manufacturer promised specific solutions in promotional materials, it is only natural that we wanted to see them in practice. At the start, it’s looking pretty good. The automatic game mode (ALLM) works, so there’s no need to manually fiddle with the settings; the console switches the TV to low latency mode by itself. Plus, we have the Game Bar, which looks impressive and allows you to check a few basic parameters without leaving the game. And this is where the good news ends.

The biggest problem with the Q7F is VRR, or rather its absence. Indeed, the appropriate icon appears in the menu, you can even see it in the Game Bar, but throughout the entire test, the function remained dead and could not be activated in any way. Even more disappointing is the matter of HGiG; this option was actually available in the beginning, but after a software update, it disappeared completely, which is just unprofessional. Therefore, the Q7F is only suitable for absolute basics. Sure, you can turn on the console, play calmer titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television one buys with gaming in mind, and it’s better to be aware of this before purchasing.
