Samsung DU7192 (VA) vs Philips PUS8209

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

Unfortunately, this is where the problems begin. A maximum brightness of 280 nits is definitely too low to feel the true HDR effect. In practice, the image resembles standard SDR more, so it's hard to speak of deeper visual experiences. On the plus side, the color gamut coverage is commendable – 91.4% DCI-P3 is a result that will be sufficient for most films. It must also be noted that the image is stable and there are no issues with sudden changes in brightness or colors. Looking at the overall picture, HDR on this TV is more of a formality than an actual added value. If we are looking for true HDR emotions, this model may not meet expectations.

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

To summarize, the "Filmmaker" mode, despite its advantages, requires refinement – especially regarding white balance and proper management of brightness in the darkest and brightest areas 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.

Philips PUS8209 offers many picture modes, but the best among them, without a doubt, is the Filmmaker mode. Despite its proud name, it has its clear issues. In the case of HD content, the white balance is characterized by a strong dominance of red, causing the image to be significantly warmer than it should be in reality. The brightness characteristic (gamma), although correct in the midtones, has serious problems at the beginning and end of the graph. Drops in the shadows lead to a loss of details in dark areas, and highlights in bright areas make some elements look unnatural.

For high-quality 4K HDR content, the situation reverses. In this case, blue dominates, leading to an effect of artificial image enhancement, reminiscent of unnatural store settings. Such an image looks unappealing and inconsistent with the creators' intentions. An additional problem is the EOTF curve, responsible for brightness in HDR materials. It deviates significantly from the reference chart, making the image appear too dark, robbing the depth and detail of HDR content.

Against this background, the errors in the Color Checker test and deviations in color palette reproduction are exceptionally large, which negatively impacts the overall image quality. The Filmmaker mode, although the best among the available options, requires significant corrections to fully deliver the director's vision.

Even with its lower models, Samsung offers extensive tools for image calibration, allowing for significant improvement of factory settings. We undertook this task, and the results proved to be more than satisfactory. The white balance, which previously exhibited strong yellowing in both SDR and HDR, has been significantly improved. Although minor deviations from the norm can be observed, 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 appropriately model the gamma in SDR materials, allowing for maximum contrast that this television can offer. The EOTF curve, responsible for HDR materials, has also been 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 cause lies in the limited brightness of the television, which does not allow for a full representation of HDR content dynamics. Nevertheless, after calibration, the picture is clearly better and more aligned with the creators' intent. For users seeking the best possible quality in this class of equipment, calibration is definitely recommended.

After calibration, the white balance for HD and 4K content has improved significantly. Although we did not achieve a perfectly flat characteristic, the effect is definitely better than before. The image on the television no longer appears artificially warm or overly cold, which significantly enhances the naturalness of the displayed content. The brightness characteristic (gamma) has also been adjusted - the biggest issues at the beginning and end of the graph have been mitigated. The EOTF curve, which is responsible for brightness in 4K HDR material, has been stabilized, eliminating problems with excessive dimming of the image. In the color palette test, some imperfections can still be seen due to average coverage of a wide color gamut, which is a limitation of the hardware itself. Nevertheless, the final effect is clearly better than before calibration - the image looks more natural and approaches the expectations for the Filmmaker mode.

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

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

The television offers a "Distortion Reduction" feature that effectively improves the gradation of tonal transitions, especially when set to the minimum level. Unfortunately, it comes at a price – the feature also smooths out details like the texture of materials. On the plus side, the operation of this option does not negatively affect the film grain, which remains intact.

As for image scaling (upscaling), the television generates a plastic, soft image that generally looks pleasant. However, in the background, one can sometimes notice issues with aliasing on some elements, such as branches or fine details, which can lower the quality of the reception. Despite these minor imperfections, the overall experience of scaling is satisfactory.

Although the Samsung DU7192 is the lowest model in the manufacturer's offer, it is equipped with a motion smoothing system. While the functionality of this solution is significantly limited compared to more expensive models, its mere presence distinguishes the television from competitors in this price range. The television supports a maximum refresh rate of 60 Hz, which is sufficient for comfortable viewing of movies and series, but may be inadequate for dynamic content such as sports. In the motion smoothing menu, we find, among others, the "Motion Blur Reduction" function. Unfortunately, its performance leaves much to be desired – regardless of the setting, the image exhibits characteristic stuttering known from material recorded at 24 frames per second, which makes this function practically fail to fulfill its role.

The 60 Hz panel in the Philips PUS8209 is mainly suited for watching movies, but there is also a certain sense of dissatisfaction here. The TV does not offer any motion smoothing feature that would allow adjusting the smoothness of the picture to individual preferences, which may be disappointing for some users.

The Samsung DU7192 is equipped with HDMI 2.0 ports, which is expected in this price range. This limitation means a lack of support for the full capabilities of the latest generation consoles, such as VRR technologies. The television only offers basic features for gamers – automatic switching to low latency mode (ALLM) and support for basic HDR for games in the HGiG standard. HGiG allows for displaying HDR content in games according to manufacturers' guidelines; however, the limited brightness of the television does not allow for fully enjoying 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 adjustments of settings for games. The presence of this feature could significantly enhance user comfort, especially among those who frequently change display modes.

The Philips PUS8209 offers basic functions useful for gamers, such as variable refresh rate (VRR), automatic low latency mode (ALLM), and a Game Bar that makes managing settings easier.

Unfortunately, due to the 60 Hz panel, the television will not meet the expectations of more demanding gamers who are counting on higher fluidity and precision of the image. Additionally, this model does not support any HDR mode dedicated to games, such as HGiG or Dolby Vision, which further limits its capabilities in this regard.
