Hisense U8NQ vs Philips PML8709

Hisense U8NQ demonstrates its capabilities in HDR, achieving a luminance score on the chart exceeding 2000 nits. In the first, third, and fifth scenes where the screen is covered in light, the television showcased very high brightness, which is impressive and allows you to enjoy the full effect of HDR. Unfortunately, in the second and fourth scenes, such as those from the film "Sicario 2," the television encounters issues maintaining brightness, resulting in disappointing scores around 250 nits. Although the large number of dimming zones should theoretically help, the algorithm responsible for their control does not always work perfectly—bright, small elements like the moon or helicopter lights are too dimmed, which takes away from the typical HDR effect. Instead of blinding brilliance, we receive a more subdued light that does not convey the full potential of HDR. Nevertheless, the television deserves commendation for its very good coverage of the DCI-P3 colour gamut at 97%. This makes colours vibrant, and most movie scenes look really good, significantly enhancing the viewing quality.

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.

The Filmmaker mode on the Hisense U8NQ television can be described as the most accurate mode present in this model. Despite its accuracy, it has significant errors in reproducing the reference image, which we will describe now. In the case of HD content, the white balance shows a distinct dominance of red, causing the image to appear overly pinkish and warm. In the comparison photo below, you can see how this effect impacts the presentation of content. The brightness characteristic also leaves much to be desired—a too low gamma causes the screen to be excessively brightened, and blacks appear washed out, making the overall image seem cooler than it should be.

For 4K HDR content, the problem is the opposite—the white balance shows too much dominance of blue, making the image take on an artificial quality and seem unnaturally sharp. All these deviations for both HD and 4K HDR content can be confirmed using the Colour Checker test, which clearly shows how the colours deviate from the correct patterns.

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 white balance for both 4K and HD content has been heavily adjusted, significantly improving the image quality. While some errors are still visible, they are not large enough to greatly affect the perception of the image. A notable improvement can also be seen in the gamma brightness characteristic — the image is no longer excessively bright, resulting in more natural blacks and better contrast.

However, like with many other Hisense models, there are noticeable issues with the EOTF curve, which is responsible for managing brightness in high-quality materials. Although it may seem correct at first glance, when the filter is applied to the "EOTF in films" chart, it is evident that the TV is somewhat "playing around" with 4K content. It is clear that the EOTF curve is significantly below the reference level, leading to an overall dimming of the image compared to the reference. We noticed this effect in previously tested scenes from the films "Pan" and "Billy Lynn." While it is not a serious issue, it is worth paying attention to. It could be significant for those seeking a display with the most faithful image reproduction. Despite this error, the image will be more enjoyable for most. Colours are represented better, and the overall image quality is significantly improved.

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.

In the context of smoothing tonal transitions, the Hisense U8NQ unfortunately struggles. The "Smooth and Gradient Picture" feature does not yield noticeable effects — there is no improvement in any setting, which is disappointing, especially in demanding scenes with a lot of subtle tonal transitions.

As for the digital processing, or so-called upscaling, the scene with the model is rendered correctly — her outline is clear, without significant cropping. Similarly, thin lines, like tree branches, have slight jaggedness, but the overall image looks plastically and softly, providing a good impression. Unfortunately, there is also an issue with so-called overscan, which results in cropping of the image at the edges. This can be annoying when watching content such as news, where the bottom information bars may be partially invisible.

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.

Hisense U8NQ is equipped with a 144 Hz panel, making it an excellent choice for both sports and gaming. The TV will also satisfy movie fans, as it features a built-in "Ultra Motion Smoothness" enhancer that allows users to control the smoothness of the image — you can choose whether you prefer a more "framey" picture or a smoother, cinematic effect. This provides great flexibility in adjusting the motion quality to individual viewer preferences.

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.

Hisense U8NQ offers everything a player might need for comfortable gameplay. The television supports a refresh rate of 144 Hz, ensuring an incredibly smooth image, especially in dynamic action games. The VRR (variable refresh rate) feature allows the image to adjust to variable frames per second, eliminating stuttering and tearing, translating to exceptionally smooth gaming. Additionally, the television is equipped with the ALLM (auto low latency mode) feature, which automatically switches the TV to game mode, minimising input lag. This means players can enjoy responsive gameplay without needing to manually adjust settings.

Hisense U8NQ also supports Dolby Vision, which is important for gamers who value high image quality, high contrast, and deep colours in games that support this format. The television also features a "Game Bar" — a function that allows quick access to essential settings during gameplay, significantly enhancing user convenience.

However, it is worth noting that despite its rich set of features, the Hisense U8NQ does not offer support for the HGiG standard, which is a popular HDR format in gaming. This may be disappointing for players expecting optimal detail reproduction in HDR scenes. Nonetheless, the other features of the television make the Hisense U8NQ a solid choice for console gaming enthusiasts, offering fluidity, high contrast, and user convenience.

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.
