Samsung DU7192 (VA) vs Philips PUS7000

On the luminance charts, the peak brightness of the television is around 280 nits. Unfortunately, such a 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 severely limits the magic of HDR, and details in the brighter parts of the image are not sufficiently highlighted. For users primarily consuming SDR content, this quality level might be acceptable but it is definitely not enough when it comes to HDR. Additionally, a DCI-P3 colour gamut coverage of 82% does not favour presenting HDR content in its full glory. The limited colour range makes it difficult for the television to reproduce vibrant and diverse hues, which is crucial for achieving a cinematic experience.

Unfortunately, the PUS7000 is not suitable for watching HDR content. This screen is simply too dark. A brightness level of 200 nits is insufficient to display this format correctly. Even if a HDR signal message appears on the screen, the image will resemble a standard SDR recording. Therefore, it’s better to stick with the latter format to avoid errors in displaying bright scenes, as you will read below. The situation is worsened by the fact that this is a classic LCD model without additional layers that improve colours, such as QLED or PFS. As a result, colours in HDR may seem washed out. Ultimately, this provides a worse effect than in the standard SDR format, which is simply better suited to the capabilities of this panel.

The best factory mode we relied on during testing turned out to be "Filmmaker." Although it is the mode that most closely aligns with the creators' intent, it still has some imperfections. In the white balance graph for both SDR and HDR, there is a clear 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 large an impact on the perception of the image. The gamma, responsible for brightness in SDR materials, performed quite well, but with one serious reservation. In the darkest parts of the image, it was too low, causing excessive brightening of those scenes, depriving the film of drama and contrast. In the case of HDR, the white balance remains at a similar level, but the EOTF curve graph draws attention. At the beginning, the curve noticeably bulges, leading to strong brightening of the darkest scenes. Then, the result sharply 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, needs 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.

We tested the television in movie mode, which theoretically should provide the best and most natural colours. And indeed, this mode is quite correct; however, when we connected the calibration equipment, its biggest flaw became apparent. The PUS7000 has significant shortcomings in displaying reds. Poorly tuned white balance and too low saturation of this colour cause the image to appear too cool. As a result, one might get the impression that the displayed content lacks vibrant colours. The situation is worsened by the fact that both SDR and HDR content are excessively brightened. This is confirmed by the gamma curve and EOTF graphs, which show that the television displays the image brighter than it should. This causes scenes to lose their depth and can make them seem slightly washed out. Fortunately, in the Philips menu, we find plenty of features to improve these aspects, so we immediately proceeded to calibration to see what we could extract from this screen.

Even with its lower models, Samsung offers advanced image calibration tools, which allow for significant improvement of factory settings. We took on this task, and the results turned out to be more than satisfactory. The white balance, which previously exhibited a strong yellow tint 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 were also able to properly model the gamma in SDR content, allowing for maximum contrast that this television can offer. The EOTF curve, responsible for HDR content, has also been improved – the image is no longer brightened or darkened as drastically as it was before calibration. Despite these successes, HDR content still struggles with high deltaE error values. The main reason lies in the limited brightness of the television, which does not allow for a full representation of the dynamics of HDR content. Nonetheless, after calibration, the image is clearly better and much closer to the creators' intent. For users seeking the best possible quality in this class of equipment, calibration is definitely recommended.

After professional calibration, it’s evident that the PUS7000 responds well to image adjustments. In this price range, that’s not a given. The effects are best evaluated in two scenarios, depending on the content we plan to watch. SDR performs the best. After our adjustments, the image looks really good. Most colour errors have dropped below level 3, which is the threshold at which discrepancies usually become visible to the naked eye. Movies, series, sports, and regular television present naturally, without unpleasant deviations. If someone mainly watches classic channels or streams in HD quality, the difference after calibration will be noticeable straight away. However, it must be said clearly that the PUS7000 is still not a television suited for proper HDR, and calibration doesn't change much in this regard. The reason lies in the hardware: colours remain too unsaturated. The television lacks solutions that widen the colour gamut, such as PFS filters or a quantum dot layer, so the panel simply cannot display the intense colours required by HDR. This is most evident in reds, which still look washed out. This limitation cannot be circumvented through menu settings, as it stems from the design of the backlighting and the panel itself.

The tonal transition smoothing feature works in two modes – 'off' and 'auto'. Turning it off causes gradation issues, while the 'auto' mode provides smooth transitions, but at the cost of grain effect and details, 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 lower resolution materials in this model is not impressive. Details are blurry, and the edges of objects may contain artifacts. This limitation means the television performs better with higher resolution content.

The PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths unwanted tonal transitions even at a low setting. However, it has its downside: with too aggressive operation, it can introduce undesirable artifacts on the screen. It would be a good idea to experiment with this setting to find the golden mean between a smooth image and the clarity of details.

The upscaling, or enhancing the quality of lower materials to 4K, is decent. The image after processing is very "soft," which is typical of almost all Philips TVs. The edges are plastic and smooth, making the image look cohesive. If someone finds it too soft, it can always be adjusted with the sharpness slider in the menu for a more pronounced effect.

Even though Samsung DU7192 is the lowest model in the manufacturer's range, 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 makes the TV stand out against the competition in this price bracket. The TV 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 sport. In the motion smoothing menu, we find, among other things, a "Vibration Reduction" feature. Unfortunately, its performance leaves much to be desired – regardless of the setting, the image retains the characteristic stutter known from material recorded at 24 frames per second, which means that this feature practically fails to fulfil its purpose.

In this regard, we actually have no good news. It might seem that the biggest downside is the lack of a 120 Hz panel, but in this price range, that's actually the norm, and it's hard to expect more. However, the worst part is that the television has no motion smoothing features. There are no supporting systems in place for either movies or sports. We have to come to terms with the fact that the image on the PUS7000 is processed "raw." This means that during dynamic scenes or fast camera movements, motion can appear choppy or unclear. We have no option to enable any smoothers that could alleviate this effect.

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

Even though the PUS7000 isn’t marketed as a gaming TV, it doesn't perform as poorly in this category as one might expect. True, it doesn't support 120 Hz refresh rates, which is understandable at this price point, but the manufacturer has included several important features that significantly improve the console gaming experience. The most important of these are VRR and ALLM technologies. VRR is responsible for synchronising the screen with the number of frames generated by the console. This means the image doesn't "tear" and remains consistent even during sudden drops in frame rates while playing. On the other hand, ALLM is a solution that automatically switches the TV to a mode with the lowest latency immediately after detecting a signal from the console. All these parameters are easily accessible thanks to the Game Bar feature. This is a special control panel for gamers that can be brought up on the screen at any time. It allows for a quick view of current settings and connection status without interrupting gameplay, which is a very convenient solution.
