Philips PUS7009 (IPS) vs Philips PUS8079

In terms of HDR effect quality, PUS7009 (IPS) performs very poorly. A brightness level of 250 nits does not allow for enjoyment of HDR effects, and the image resembles a more standard SDR. There is no talk of dynamic effects or vivid bursts of light. The coverage of the DCI-P3 colour gamut is only 75%, which is decidedly insufficient. The lack of full colour coverage means that the colours are not as vibrant as they should be, resulting in a flat and unconvincing image. There are no aspects for which this model could be praised in the context of HDR.

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 television was tested in film mode, which – despite its name – does not provide accurate image display. The white balance in both 4K HDR and HD/SDR content is characterised by drops in red, causing the image to appear cooler and the colours to lose their natural warmth. The gamma brightness characteristics and the EOTF curve confirm that the television has issues maintaining appropriate brightness – it heavily boosts it, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where the entire image appears as if it has a milky filter applied. Additionally, the limited coverage of a wide colour gamut also does not favour quality – colour checker tests indicate significant colour variations, making it difficult to achieve faithful image reproduction.

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.

After calibration, the picture has significantly improved, especially in terms of white balance, which is now more stable, and the shades have taken on a natural quality, eliminating the previous impression of a picture that was too cool. Calibration has brought noticeable benefits in terms of tonality – shadows and midtones are now more realistic, and the overall effect seems more harmonious. Unfortunately, hardware limitations still affect the quality of the image. The brightness characteristics remain problematic, despite our efforts, and due to the poor coverage of the DCI-P3 and BT.2020 colour gamut, delta E errors are still at a high level. Although calibration has improved some aspects, the television still does not allow for complete satisfaction.

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.

When it comes to tonal transitions in low-quality material, a feature named "Distortion Reduction" (set to "minimum") effectively improves gradation, eliminating ugly tonal transitions. However, this setting on Philips televisions is quite aggressive – while it does not blur the grain or good-quality material, it can introduce undesirable effects and blur elements that should remain sharp when the signal is poorer.

In terms of image scaling, Philips PUS7009 performs reasonably well. A significant advantage is the absence of cropped image edges, meaning no overscan, which allows for the display of the full frame without loss. The image is noticeably enhanced, making characters and backgrounds, such as the model or branches in the background, appear quite detailed and natural, even with lower quality signals. Although scaling is not perfect, as it can remove desirable details in the distance, the results are good enough to satisfy most users.

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.

Philips PUS7009 does not have any motion smoothing features for films, which means we cannot choose whether the picture should be more choppy or more cinematic. These features could improve more dynamic scenes. As for motion blur, despite using a 60Hz IPS panel, the situation looks quite good. The response time between pixels is better than in versions with a VA panel, which keeps motion blur at an acceptable level and does not significantly affect the comfort of watching dynamic scenes.

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.

In terms of compatibility with consoles, Philips PUS7009 is suitable for casual gamers. Despite the use of HDMI 2.0, the television offers access to features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Game Bar. ALLM automatically switches the television to low latency mode, allowing for quicker response times during gameplay, while VRR dynamically adjusts the refresh rate to reduce the tearing effect. Game Bar is a tool that provides quick access to game settings and real-time monitoring of parameters - although we believe it appears the weakest compared to competing Game Bars.

Unfortunately, more demanding gamers may be disappointed. The Philips PUS7009 does not support advanced HDR formats in games or high refresh rates, due to the use of a 60 Hz panel. The lack of support for these features limits the television's ability to deliver smooth and fully detailed experiences during dynamic gameplay.

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.
