Samsung DU7192 (VA) vs Philips PUS7009 (VA)

In the luminance charts, the peak brightness of the television is around 280 nits. Unfortunately, this value is too low to fully enjoy HDR effects, which require significantly higher luminance. In the tested materials, such as The Meg and Gemini Man, the lack of adequate brightness severely limits the magic of HDR, and the details in the brighter parts of the image are not sufficiently highlighted. For users primarily consuming SDR content, this level of quality may be acceptable, but it is definitely not enough when it comes to HDR. Additionally, the coverage of the DCI-P3 colour palette at 82% does not favour presenting HDR content in its full glory. The limited colour gamut makes it difficult for the television to reproduce vibrant and diverse colours, which is crucial for achieving a cinema-like experience.

In terms of HDR effect quality, Philips PUS7009 performs very poorly. A brightness level of 250 nits does not allow one to enjoy HDR effects, and the image resembles more of a standard SDR. There is no question of dynamic effects or vivid light bursts. 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 for which this model could be praised in the context of HDR.

The best factory mode we relied on during testing turned out to be "Filmmaker". Although this mode is the closest to the creators' intent for films, it is not without certain imperfections. The white balance chart in both SDR and HDR clearly shows a dominance of red, resulting in significant yellowing, particularly noticeable in whites and on actors' faces. In HDR mode, there is also a slight dominance of green, which, however, does not have as much impact on the perception of the image. The gamma, which is responsible for brightness in SDR materials, performed quite well, but with one serious caveat. In the darkest parts of the image, it was too low, causing excessive brightness in those scenes, depriving the film of drama and contrast. For HDR, the white balance remains at a similar level; however, the EOTF curve chart draws attention. At the beginning, the curve clearly bulges, leading to a strong brightness in the darkest scenes. Then the result suddenly drops below the reference line, resulting in an overly dark image and a loss of dynamics in the brighter parts.

In summary, the "Filmmaker" mode, despite its advantages, requires refinement – especially regarding white balance and proper management of brightness in the darkest and brightest parts of the image. In its current form, it may be acceptable for less demanding users, but for viewers expecting precise image reproduction, it may leave much to be desired.

The television was tested in movie mode, which – despite its name – does not provide accurate image display. The white balance in both 4K HDR and HD/SDR content shows 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 struggles to maintain appropriate brightness – it boosts it significantly, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where everything looks as if it has a milky filter applied. Additionally, the limited coverage of a wide colour palette also does not favour quality – color checker tests indicate significant colour variations, making it difficult to achieve faithful image reproduction.

Even for its lower models, Samsung offers advanced image calibration tools, which allow for significant improvement of the factory settings. We undertook this task, and the results turned out to be more than satisfying. The white balance, which previously exhibited a strong yellowish tint in both SDR and HDR, was significantly improved. Although slight deviations from the norm can be noticed, the overall effect is much cleaner and more natural than before calibration. As a result, whites and skin tones look much better. We also managed to properly shape the gamma in SDR materials, which allows for achieving the maximum contrast that this television can offer. The EOTF curve, responsible for HDR materials, was also improved – the image is no longer brightened or darkened as drastically as it was before calibration. Despite these successes, HDR materials still struggle with high deltaE error values. The main reason lies in the limited brightness of the television, which does not allow for a complete representation of the dynamics of HDR content. Nevertheless, after calibration, the image is clearly better and more aligned with the creators' intentions. For users seeking the best possible quality in this class of equipment, calibration is definitely recommended.

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

The tonal smoothing function operates in two modes – "off" and "auto". Turning it off causes gradation issues, while the "auto" mode ensures smooth transitions, but at the cost of grain and detail, which are often blurred. Due to these limitations, we do not recommend using this feature, as confirmed by our tests conducted with it turned off.

Scaling of lower resolution materials in this model is not impressive. Details are blurred, and the edges of objects may contain artifacts. This limitation makes the television perform better with higher resolution content.

When it comes to tonal transitions in low-quality material, the function called "Distortion Reduction" (the "minimum" setting) effectively improves gradation, eliminating unattractive tonal transitions. However, this setting on Philips televisions is quite aggressive – while it does not blur 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 decently. 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, look quite detailed and natural, even with lower quality signals. Although scaling is not perfect, as it can remove desired details in the distance, the effects are good enough for most users to be satisfied.

Although the Samsung DU7192 is the lowest model in the manufacturer's range, it is equipped with motion smoothing technology. While the functionality of this solution is significantly limited compared to more expensive models, its presence alone distinguishes the television amidst competitors in this price bracket. The TV supports a maximum refresh rate of 60 Hz, which is sufficient for comfortable viewing of films and series, but may be inadequate for dynamic content such as sports. In the motion smoothing menu, we can find, among other things, the "Judder Reduction" feature. Unfortunately, its performance leaves much to be desired – regardless of the setting, the picture exhibits the characteristic stutter known from materials recorded at 24 frames per second, making this feature practically ineffective.

Philips PUS7009 does not have motion smoothing capabilities, which means there is no option to adjust the image for a more choppy or smoother, cinematic effect. Such features could positively influence the reception of dynamic scenes. In terms of motion blur, this model is equipped with a 60 Hz VA panel, which offers slightly worse results than the variant with an IPS panel. The VA panel introduces minimally greater motion blur, although the differences are not significant and should not pose a problem for most viewers.

Samsung DU7192 is equipped with HDMI 2.0 ports, which is expected in this price range. This limitation means there is no support for the full capabilities of the latest generation consoles, such as VRR technologies. The television only offers a basic feature for gamers – automatic switching to low latency mode (ALLM), and support for basic HDR for games in the HGiG standard. HGiG allows for the display of HDR content in games according to manufacturers' guidelines; however, the limited brightness of the television does not allow for full enjoyment of the effects that this standard offers. Unfortunately, there is a lack of conveniences such as GameBar, which is increasingly found even in cheaper models and greatly facilitates quick adjustment of settings for games. The presence of this feature could significantly enhance user comfort, especially for those who frequently change display modes.

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 television to low latency mode, which speeds up responses during gaming, while VRR adjusts the refresh rate to minimise screen tearing. Game Bar provides quick access to gaming settings and monitors key parameters, although it visually 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 the ability to display smooth and detailed images in dynamic scenes, which may not satisfy fans of fast-paced action games.
