Philips PUS8079 vs Samsung DU8002 (IPS)

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 HDR effect on the DU8002 television leaves much to be desired. A brightness level of 300 nits cannot provide a true high dynamic range experience, which makes the viewed content resemble more of a standard SDR than impressive HDR. Scenes that should dazzle with brilliance and detail appear muted and lacking in depth. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 colour gamut at 92%. This means that colours are vivid and saturated, which may satisfy viewers who prefer rich tones, even if the HDR effect does not fully meet expectations.

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.

The DU8002 offers a Filmmaker mode, which is intended to provide an authentic image reproduction in line with the creators' vision. Unfortunately, despite the promising name, the results are far from ideal. The white balance in this mode shows significant drops in blue, leading to a noticeable yellowing of the image, as seen in our comparison photo. Colour Checker tests confirm these errors. As for brightness, the gamma characteristic is too low compared to the reference line of 2.4, resulting in excessive screen brightness. A similar issue occurs with 4K content – the EOTF responsible for brightness in 4K material shows significant increases above the reference line, leading to excessively bright small light elements. As a result, the Filmmaker mode in the DU8002 does not meet expectations and instead of offering high quality, presents an image full of tonal and colour inaccuracies.

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.

Samsung is one of those companies that offers advanced tools for improving picture quality in its televisions, including a 20-point white balance adjustment. Even in the budget model DU8002, with the right adjustments, surprisingly good results can be achieved. The white balance, especially for HD content, is really good – tests on the Colour Checker palette confirm accuracy levels of 2–1.5, which speaks to this television's considerable capabilities in colour reproduction. In 4K content, although not as perfect as in lower quality materials, the overall picture looks significantly better.

The gamma brightness has also been heavily adjusted, meaning the picture is not overly bright and looks more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it is clear that the television, due to its low contrast matrix, struggles. The EOTF also drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where calibration is worth investing in. Although construction flaws, such as the type of backlighting, cannot be completely eliminated, colour accuracy is surprisingly good, especially given its price.

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.

Smoothing tonal transitions on the DU8002 television leaves a mixed impression. Although the menu features an option for smoothing tonal transitions, in practice it yields no results and may even generate unwanted side effects.

Nevertheless, the television performs excellently with upscaling, or digital image processing. The test pattern with the model looked really good – the image is not excessively jagged, and the overall presentation is decent and pleasant to the eye. This is definitely good news for those planning to watch traditional television on this model.

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.

The DU8002 with a 60 Hz panel is a television that performs better for watching films than for intense gaming. The motion smoothing feature acts as a fluidizer, smoothing out movement and giving scenes a more fluid appearance, which is helpful for movie screenings. In the context of gaming, this model is more suited for casual entertainment.

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.

DU8002 is a television that is primarily suitable for casual gamers. The 60 Hz panel does not provide the highest motion smoothness, so in dynamic games, there may be a lack of that extra fluidity in the picture. On the plus side, it features ALLM and HGiG functions, which automatically adjust the picture settings for HDR gaming, enhancing the gaming experience. Unfortunately, the television is equipped only with HDMI 2.0 ports, so we will have to forget about more advanced features like VRR or support for 4K at 120 Hz. With this equipment, we will have to settle for less if we expect a full set of gaming features.
