Philips PML8709 vs Hisense E7Q / E79Q

Looking at the results of the contrast, we expected that the algorithms responsible for the operation of 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 only 350 nits, which is definitely too little to fully enjoy the effects of HDR. In practice, the television barely stands out against the backdrop of an average SDR. The situation becomes even more surprising for test scenes, such as the second one from the film Life of Pi or Sicario 2. Small light elements reach only 120 nits there, making them practically imperceptible. Such a level of brightness is completely at odds with contemporary 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 colour gamuts – DCI-P3 at 97% and BT.2020 at 83%. This means that the colours are saturated and well-reproduced, which may improve the overall experience of watching HDR materials, if only a little. However, the lack of adequate brightness means that even this cannot save the Philips PML8709 in this category.

The Hisense E7Q / E79Q is a television with average brightness, with a peak luminance level of around 350-380 nits. This is an absolute minimum that allows for HDR content to be viewed in a way that is close to the creators' intentions, although without a distinct "wow" effect. Synthetic test results on white screens have been confirmed in practice – in film scenes, the bright parts of the image are stable and quite uniform, but it's hard to speak of a true "light punch." In everyday use, for example, when watching Netflix or YouTube, the HDR effect is acceptable and is perfectly sufficient for most users. However, it must be stated clearly – this is not the level of top-end screens, and one should not expect that in this price range. Fortunately, the Hisense E7Q / E79Q has an advantage that allows it to gain quite a few points: it features a PFS LED QLED panel, utilising an additional phosphor layer that improves colour reproduction. The measured range of the DCI-P3 colour gamut is about 92%, which means that colours in most scenes are vibrant, well-saturated, and pleasant to the eye, particularly for this price bracket.

Although theoretically the Filmmaker mode on the Philips PML8709 should provide natural colour reproduction, in reality it resembles store mode more closely. In the white balance, both for HD and 4K content, there is a clear dominance of the blue colour. This causes the image to appear washed out and cold, which is particularly noticeable in the comparative photo below.

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

These significant issues in white balance and brightness characteristics lead to noticeable errors in colour reproduction, which can be easily seen in films as well as in the Colour Checker test. The colours are inaccurate, impacting 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, the Hisense E7Q / E79Q television was truly impressive. After the first measurements, it became clear that the white balance was quite well tuned, with the only minor deviation being a slight tendency towards a purple tone, which we mentioned earlier. However, this did not significantly impact the overall character of the image – it remained coherent and pleasant to view. A much larger issue turned out to be the brightness characteristics (gamma) in SDR content and the EOTF curve in HDR films. The television noticeably brightened the image, flattening the contrast and diminishing its depth. Gamma values could drop from the reference 2.4 to around 1.9, making the image look as if it were covered with a thin, milky layer. Fortunately, this is a problem that can be relatively easily corrected through calibration.

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 was not without difficulties. White balance was one of the biggest challenges – despite our efforts, this can be described as a fight against windmills. We managed to correct it significantly, resulting in the image now looking much better than in the factory settings, but it is still far from perfect. Particularly in some scenes, a subtle dominance of blue is visible, although not as intense as before. We achieved a substantial improvement in brightness characteristics – gamma now appears much more stable. The EOTF curve initially looks correct, however, when analysing film content, it is evident that the television struggles to maintain the appropriate characteristics. The algorithms are "battling," trying to adjust brightness, which may stem from the limited number of dimming zones that do not always cope with more complex scenes. Overall, the image after calibration looks much more pleasing to the eye – colours are more natural, and errors in colour reproduction have been minimised. Although it is still not perfect, the Philips PML8709 now performs significantly better than in the factory settings.

The biggest beneficiary of calibration in the case of the Hisense E7Q / E79Q was undoubtedly the SDR mode. It managed to achieve an almost perfect image – most errors in the Color Checker test dropped below a value of 3, and often even 2, which is an outstanding result for this class of equipment. The greatest improvement came from equalising the brightness characteristic (gamma), which meant the image no longer appeared washed out and regained its natural depth. In HDR content, it was also possible to improve colours and eliminate the purple tint mentioned earlier, but errors in the Color Checker measurements were still noticeable. This is due to the fact that – as is often the case with Hisense televisions – the screen manipulates brightness quite heavily, overemphasising some colours. This was also indicated by the EOTF curve, which was slightly above the reference values, suggesting these minor issues with excessive brightness. Despite this drawback and the design limitations that emerge with HDR content, the Hisense E7Q / E79Q gained quite a lot after calibration. In everyday use, the television presents a consistent, natural, and pleasant image, and the difference compared to the factory settings is enormous.

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, which means that certain tonal transitions may still appear a bit uneven. An additional drawback is that this function also smooths out other details, such as the textures of materials like a shirt, which can affect the sharpness of the image.

When it comes to image scaling, the television performs very well. The image appears plastic and free of noticeable "jaggedness." This effect may appeal to many users, although some may prefer a more pronounced appearance. Fortunately, the television allows for sharpness adjustment, and this enables us to tailor the image to individual preferences.

In the case of the Hisense E7Q / E79Q, upscaling and digital image processing are not the strongest aspects of this television. It is evident that the manufacturer has opted more for simplicity rather than advanced image processing algorithms. The television does not offer any features to smooth tonal transitions or systems to improve image clarity, resulting in lower resolution materials looking simply very raw. On the screen, you can notice subtle compression edges that better processors in other models can effectively hide.

During the HD material tests, we noticed that the E7Q tries to artificially enhance detail, which sometimes works, and at other times has the opposite effect – the image becomes soft, slightly blurred, at times even “watery.” There is no aggressive sharpening that ruins naturalness, but there is also no finesse in the detail integration that better image converters offer.

The Philips PML8709 is one of the few models with mini-LED technology on the market, offering a refresh rate of 60 Hz. Although it is not a panel for the most demanding gamers, it should satisfy those who mainly watch films. The television is equipped with the "Motion Style" function, which is a motion smoother that allows you to adjust the smoothness of motion according to preferences – from a more "plastic" look to a cinematic aesthetic with clearly visible frames.

Hisense E7Q / E79Q is a television with a 60 Hz screen, so fans of 4K sports may feel a slight disappointment – we simply won’t see such smooth images here as in more expensive models with higher refresh rates. Fortunately, the situation is much better for films. Cinematic materials recorded at 24 frames per second can be displayed here using a motion smoothing feature, allowing the user to tailor the picture to their own preferences – either more cinematic with visible frames or smoother, in a theatrical style.

Philips PML8709 is a television aimed more at casual gamers, primarily due to its 60 Hz panel, which may not meet the expectations of the most demanding users. However, for those who appreciate gaming 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 deliver smoother visuals without annoying stutters. Furthermore, in terms of HDR, it includes an HGiG implementation that adjusts HDR effects to the specifics of games, providing a more natural image in properly optimised titles. Unfortunately, it lacks 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 viewing and modification of the most important gaming-related settings. This is a simple but useful feature, especially for those who often switch configurations between different types of gameplay. Despite some limitations, Philips PML8709 offers a solid set of features for less demanding gamers.

Hisense E7Q / E79Q is truly a successful television for gamers, even though it does not support 4K signal at 120 Hz. The manufacturer, however, has ensured a set of features that until recently could only be found in more expensive models. There is ALLM, meaning automatic switching to low latency mode, allowing the television to activate game mode with very low input lag by itself. We also have VRR, functioning up to 60 Hz – while this may not look impressive on paper, in practice it is fully sufficient, as most games on consoles do not exceed this limit. All these settings can be quickly found in the Game Bar panel, a convenient menu created specifically for gamers. From this interface, one can change picture modes, enable a frame counter, or even... an on-screen reticle – humorously named "target point" in the Vidaa system, which is a result of awkward translation from the Chinese manufacturer.

Special praise should be given to the ability to play in 1080p at 120 Hz, which significantly improves the fluidity and responsiveness of the image. Therefore, if someone wants to play a few titles at a higher refresh rate, they can simply lower the resolution and enjoy much smoother motion. Despite the lack of 4K@120Hz, the Hisense E7Q / E79Q performs really well as a gaming television – especially for those who are not looking for perfection but rather a solid and fast screen for everyday gaming.
