Sony Bravia 8 (XR80) vs Philips PML8709

The Sony Bravia 8 performs commendably in terms of HDR brightness, reaching a peak of 880 nits. This level is sufficient to render lighting effects effectively in most scenes. In tested clips from Life of Pi and Sicario 2, the television demonstrated vibrant, detailed imagery that captured the atmosphere of these films beautifully.

However, challenges arise in scenes with consistently high brightness, such as in The Meg, where the display's limitations become apparent. In these situations, OLED technology can struggle, with brightness levels dropping to around 450 nits, which can be less satisfying when intense illumination is needed throughout a scene. Despite this, the Sony Bravia 8 remains a strong contender, offering excellent DCI-P3 colour gamut coverage and 74% BT.2020 coverage. These attributes result in rich, accurate colours and fine details, enhancing HDR content and providing an enjoyable viewing experience.

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.

The best factory mode on the Sony Bravia 8 television is IMAX Enhanced, offering the most cinematic experience, though it isn't perfectly calibrated. The TV attempts to replicate cinematic settings as accurately as possible, but some issues are evident. Starting with white balance, both for SDR and 4K content, there is a noticeable blue dominance, making the image appear too cold and lacking in natural warmth. Colour Checker tests reveal a shift towards cooler tones, affecting colour accuracy and making the image feel less lifelike.

Regarding brightness and contrast, the gamma shows a significant drop towards the end of the spectrum, meaning dark details may become too shadowed, and bright areas too intense, causing a loss of subtlety and detail. This is particularly noticeable in the sky, as seen in the comparison image. Additionally, the EOTF curve is considerably above the reference value, making bright elements overly intense. As a result, users may experience an unnatural image, with bright parts losing detail and negatively impacting the overall viewing quality.

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.

The calibration process of the Sony Bravia 8 television resulted in significant improvements in image quality. The white balance was notably enhanced for both SDR and 4K HDR content, with minimal errors in the middle section of the graph. Gamma calibration was one of the biggest improvements, eliminating previous dips that had impacted brightness stability and the reproduction of detail in dark areas. The EOTF curve was also corrected, making bright elements appear more natural and improving the overall tonal balance.

However, the most attention should be given to colour reproduction, where some issues persist despite calibration. Sony has omitted the CMS system in this model, which would allow for more precise colour control. As a result, the Colour Checker test for 4K content still reveals significant colour inaccuracies. Despite these limitations, calibration is still recommended, as the improvements in brightness and contrast are noticeable and greatly enhance the overall image quality.

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.

The fluidity of tonal transitions in lower-quality materials on the Bravia 8 is lacking. Unfortunately, the gentle gradation function, which was available in previous models, is missing, which is a significant drawback. The digital noise reduction feature can improve tonal transitions, but it often removes fine details, such as clouds in scenes from The Martian, which may not be to everyone's taste. On the other hand, the digital processing in the Sony XR80 is quite effective. In test scenes, it performed well without noticeable flaws, and the branches in the background remained smooth without jagged edges. This indicates that the Bravia 8 is capable of handling complex low-resolution image details with relative ease.

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.

The Sony Bravia 8 offers a maximum refresh rate of 120 Hz, ensuring smooth viewing of dynamic content such as sports and games, with sharp and fluid motion. For more demanding users, the Sony XR80 features an advanced motion smoothing system, divided into three settings: Smoothness (Film), Smoothness (Camera), and Clarity. The first two settings adjust the level of blur and smoothness, while the Clarity setting will be discussed in more detail below. Each of these parameters can be customised to suit individual preferences, allowing users to fine-tune the settings for the optimal viewing experience.

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.

The Sony Bravia 8 has greatly improved its compatibility with consoles compared to earlier models. It supports variable refresh rate (VRR), which eliminates screen tearing and can sync with graphics cards for smooth visuals. The Auto Low Latency Mode (ALLM) reduces input lag, a crucial feature for fast-paced games. Additionally, Dolby Vision with low latency enhances HDR effects, offering stunning visuals during gameplay.

The Sony XR80 also includes a Game Bar, which provides quick access to settings and monitoring tools during gaming. A notable feature is the option to enable a virtual crosshair on the screen, giving players a potential advantage in shooter games.

However, there are some drawbacks. The TV lacks support for 1440p@120Hz resolution, which would benefit users with less powerful graphics cards. Furthermore, the Sony XR80 has only two HDMI 2.1 ports, one of which is typically used for connecting an audio system via eARC, limiting the number of available ports for next-gen consoles.

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.
