Samsung DU7192 (IPS) vs Philips PUS7009 (VA)

The maximum luminance in HDR materials is 245 nits, which is often surpassed by even lower results. Such values will definitely not be sufficient for comfortable viewing of HDR materials, due to the lack of appropriate image dynamics and colour distortions caused by the low brightness of the unit. Although the manufacturer has equipped its device with an HDR format offering dynamic metadata, HDR10+, which is what we're talking about, is very rarely used compared to Dolby Vision, which Samsung has not yet introduced in its televisions. It’s also worth mentioning that Samsung DU7192 offers only 82% coverage of the wide DCI-P3 colour gamut, which is another reason we shouldn't provide a signal in a wide dynamic range, as colour losses will be very noticeable. Samsung DU7192 delivers high-quality image that will satisfy most users.

In terms of HDR effect quality, Philips PUS7009 performs very poorly. A brightness level of 250 nits does not allow for an enjoyable HDR experience, and the image resembles more of a standard SDR. There’s no mention of dynamic effects or vivid bursts of light. The coverage of the DCI-P3 colour gamut is only 75%, which is definitely 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 of this model that could be praised in the context of HDR.

The best factory mode we used throughout the testing process was "Filmmaker". This, like the vast majority of modes, had its flaws. Starting with the most basic graph, which is white balance, we can notice a significant dominance of red colour, both in SDR mode and HDR. Although in the latter there was also some green, which didn’t have a major impact on the overall perception. A graph with such results, in both cases, gives us an image characterised by strong yellowing, clearly visible on whites and on the faces of the actors. Another important graph, if not more important, is gamma. This, which is supposed to control contrast in materials with a standard colour palette, was quite good in factory mode with one "but" regarding the beginning. In the darkest scenes, it was significantly lowered, resulting in strong brightening, which left the film lacking contrast and suspense overall. As we mentioned, HDR materials regarding white balance remained at a similar level. The main change is the EOTF curve graph. At the very beginning, we can observe a bulge, which, just like in the case of gamma, strongly brightened the darkest scenes. However, after that, the graph significantly changed its characteristics and the measured result dived below the reference line, causing the film to lose even more dynamism.

The television was tested in movie mode, which - despite its name - does not provide correct image display. The white balance in both 4K HDR and HD/SDR content shows drops in the red color, making the image cooler and the colors lose their natural warmth. The gamma brightness characteristic and EOTF curve confirm that the television struggles to maintain appropriate brightness - it excessively boosts it, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where everything looks as if a milky filter has been applied. Additionally, the limited coverage of a wide color gamut does not contribute positively to quality - color checker tests indicate significant color fluctuations, making it difficult to achieve faithful image reproduction.

Samsung has equipped even its lowest-end TVs with advanced tools for carrying out the calibration process. So we got to work, and the results of our efforts are more than satisfactory. The white balance, which previously had a strong yellow tint in both scenarios, now looks much, much better, even if there are slight deviations from the norm. The picture will still look significantly cleaner than it did before the calibration process. We managed to model the gamma in SDR materials very well, allowing the image to be as contrasty as the TV permits. The EOTF curve has also changed its face and doesn’t brighten or darken the image in such a drastic manner. However, it is worth mentioning that in the case of HDR materials, the deltaE errors are still very high, but this is due to the unit's insufficient brightness.

After calibration, the image significantly improved, especially in terms of white balance, which is now more stable, and the hues have gained a natural quality, eliminating the previous impression of an overly cool image. The calibration brought noticeable benefits in tonal quality – shadows and midtones are now more realistic, and the overall appearance seems more harmonious. Unfortunately, hardware limitations still affect image quality. Brightness characteristics remain problematic, despite our efforts, and due to poor coverage of the DCI-P3 and BT.2020 colour gamut, delta E errors are still at a high level. Although calibration improved some aspects, the television still does not provide full satisfaction.

Let's return for a moment to the tonal transition smoothing function. We can set it in only two ways - off and auto. As you can easily guess, the first of these causes significant issues with gradation. However, if we set the second option, both movies and series will offer us smooth colour transitions. It is worth mentioning, though, that this function has its drawbacks. It heavily interferes with the director's intent, softens the film grain effect, and worse, often misinterprets small details, blurring them as well. Consequently, we consider that this function does not exist and do not recommend using it, as this is how the smoothness of tonal transitions was tested on the tested display.

The next thing we will check in this paragraph is the image scaling process, which is extremely important when watching material in lower resolution. Unfortunately, as this is the manufacturer's lowest model, this function doesn't work very well. All details are heavily blurred, and a characteristic white halo forms around the characters.

When it comes to tonal transitions in low-quality material, the function called "Distortion Reduction" (setting “minimum”) effectively improves the gradation, eliminating unsightly tonal transitions. However, this setting on Philips televisions is quite aggressive – while it does not blur grain or good quality material, it can introduce unwanted effects and blur elements that should remain clear with a poorer signal.

In terms of image scaling, Philips PUS7009 performs reasonably well. A major advantage is the lack of cropped edges of the image, meaning no overscan, which allows for displaying the full frame without losses. 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 desired details in the distance, the results are good enough to satisfy most users.

Despite the fact that Samsung DU7192 is the lowest model in the manufacturer's portfolio, it has implemented a motion smoothing system. Although it is quite limited in features compared to higher models, its very existence is a significant plus in the context of competition in a similar price range. The maximum refresh rate that we will give to the tested television is 60 Hz, which is entirely sufficient for films and series, although not when it comes to sports. In the motion smoothing menu, we find two functions responsible for improving smoothness. These are "Motion Blur Reduction" and "Clear Motion (LED)". We'll discuss the latter a bit later. Let's focus on the former, as it is quite mysterious. Unfortunately, despite its presence, we did not find any usefulness. At each of the settings, the picture looked the same, characterised by the typical judder known from materials recorded at 24 fps.

The panel Samsung DU7192 features an average response time. It's worth mentioning that due to this specific type of panel, it is better than VA panels in a similar price range. Therefore, it can be said that it won't be the worst in terms of watching sports.

Philips PUS7009 does not have motion smoothing features, which means there's no option to adjust the picture for a choppier or smoother, theatrical effect. Such features could positively affect the viewing of dynamic scenes. In terms of motion blur, this model is equipped with a 60 Hz VA panel, which delivers slightly worse results than the IPS panel variant. The VA panel introduces minimally greater motion blur, although the differences are not significant and should not pose a problem for most viewers.

The Samsung DU7192 television is equipped only with HDMI 2.0 ports, which isn’t surprising considering the device’s price and its consumer profile. Therefore, it’s also logical that we won’t achieve maximum quality on the latest generation consoles. That’s why it only features the most basic options for gamers, namely ALLM. It’s a pity the manufacturer didn’t implement at least a GameBar, as this is now standard, even in lower-end TVs, and could offer significant conveniences in terms of quickly changing settings.

In terms of compatibility with consoles, Philips PUS7009 is likely to satisfy casual gamers. Although equipped with HDMI 2.0, it offers features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Game Bar. ALLM automatically switches the TV to low latency mode, which speeds up responses during gaming, and VRR adjusts the refresh rate to minimise screen tearing. The Game Bar provides quick access to game settings and monitors key parameters, although visually it falls short compared to competing solutions. However, more demanding gamers may feel underwhelmed. Philips PUS7009 does not support advanced HDR formats in games, and the 60 Hz panel limits its ability to display smooth and detailed images in dynamic scenes, which may not satisfy fans of fast-paced action games.
