Philips PUS8079 vs Hisense E7Q / E79Q

The maximum brightness in content with a wide tonal range at a level of 202 nits is extremely low and, in practice, does not allow for watching films and series on streaming platforms in the highest quality. It is worth mentioning that in this case, the use of the HDR format equipped with dynamic metadata will not help either. Why won't it help? Because the only such format implemented in the television is HDR10+, which is extremely unpopular, and films recorded in this format are scarce. It is also worth noting that PUS8079 utilises WLED backlighting, which unfortunately is not the best solution, resulting in a coverage of the wide DCI-P3 colour gamut of only 80%. The result of this situation is significantly less intense colours in HDR content.

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.

The best factory mode in terms of colour reproduction and fidelity to the director's vision was "Film". Admittedly, it was the best among the pre-defined modes, although it had significant discrepancies between what the film's author wanted to convey and what the tested television displayed. Both in SDR and HDR materials (though to a lesser extent in the latter), the white balance, which is the most fundamental element responsible for image purity, turned out to be somewhat of a repeat of the vivid mode, with the blue tint known from displays on shop shelves. Moving directly to SDR materials and what is responsible for contrast, namely gamma, we see that it is significantly reduced. This leads to cutting down on an already limited contrast range and brightening the entire image. In the EOTF curve, which is responsible for the increase in brightness pace in HDR materials, we observe a sharp drop below the reference line, which, given the limited light output of the television, had a significant impact on the perception of these contents, which were even darker. We will not separate the assessments of the colours themselves, as in both cases they achieved astronomical deltaE values, being simply completely different from what they should be.

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.

Fortunately, Philips implements advanced image correction tools in all its televisions. SDR materials benefited the most here, and the enormous deltaE errors were significantly corrected, both white balance and gamma underwent considerable reshaping. Although one cannot speak of a reference image here, it is definitely better, and films or series can be watched without causing headaches, and above all, eye strain. Naturally, HDR materials, due to the very low luminance of the television, could not be corrected to the same extent as those with a standard colour palette; however, the EOTF curve and white balance were roughly straightened out. Unfortunately, that was all we managed to squeeze out of our unit, although it should be noted that each unit is different and has completely different errors, smaller or larger.

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.

We will return once more to the issue of tonal transitions but in the context of the overall improvement of image quality. As we can observe in the photograph on the left side, the enhancement function for gradation works brilliantly. Moreover, it offers several settings, and each of them, even the lowest one, provides beneficial effects, and what’s more, it does not soften the effect of film grain. We will reiterate that this function is the greatest advantage of the tested television.

Next, we will take a look at image scaling. Here, the tested television performed worse. We can primarily notice severely jagged fine details and a characteristic white halo around the figures. One must not forget about the considerable artificial sharpening of the image.

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.

This paragraph, unlike the others, will be extremely short. The reason for this state of affairs is the lack of implementation of even the most basic motion smoothing function, which was to be expected, considering the price of the device. We also note that we are dealing with a VA panel, which in itself will not have the best sharpness under the sun. This type of panel is primarily associated with high contrast, which goes hand in hand with quite slow response times, as we can clearly read from the matrix analysis results. As you can see, from the photos taken in quick motion, the image is typically blurred for this type of panel. Although it will not be the ideal option, it can conditionally be used for watching sports, keeping in mind the less than optimal sharpness in motion. It is worth mentioning that movies will be characterised by judder, as the television does not have any, even the simplest, motion smoother.

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 PUS8079 offers only the most basic support for gaming in the form of ALLM, VRR, and a Game Bar. The most important information is that thanks to the implementation of the feature responsible for dynamic frequency changing, the picture is actually quite smooth for this price range and does not suffer from tearing.

A slightly greater nod towards gamers is the introduction of the Game Bar, allowing for real-time editing of settings. This means we won't have to exit the game to make any changes to the picture. Importantly, it has not been stripped of options known from higher models. Thus, we will find features such as shadow enhancement for better visibility in dark areas and a colour filter for players with visual impairments.

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.
