Samsung S90D / S94D 48" (WRGB OLED) vs Philips PUS7000

In the tested film scenes, the television Samsung OLED 48 S90D achieves impressive brightness results, surpassing 800 nits in the first four shots, which can be considered a very good result. In the case of the final shot, where a fullscreen flash of sunlight is visible, the brightness drops to around 400 nits, but still remains at an acceptable level. However, it's worth noting that this model in larger sizes offers higher values, exceeding the "barrier" of 1000 nits. Additionally, speaking of the DCI-P3 colour space coverage at 97% is an excellent result, which guarantees extremely rich and realistic colour reproduction, further enhancing image quality. However, once again it should be remembered that the panel in the 65' variant equipped with a QD-OLED panel will be even better in this aspect. For those hesitating in choosing the size of the S90D model, it is worth mentioning that the larger versions of this television offer better HDR effects, and consequently, higher scores in our tests.

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

The S90D Samsung television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more demanding users. This mode can seem overly warm, and users switching from Standard mode may experience a slight shock. It's worth noting that this state of affairs is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue, causing colours to become warmer than they should be. In practice, this means that some shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma graph indicates slight fluctuations, causing the image to be minimally darker, especially in shadows. This may affect less distinct details in darker scenes. Conversely, in 4K HDR materials, the EOTF curve is situated above the recommended line, leading to some parts of the image being displayed too brightly, which can cause clipping in the brightest areas. Overall, the Samsung S90D presents a solid image right out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

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, after connecting the calibration equipment, its biggest flaw came to light. The PUS7000 has significant shortcomings in displaying red. Poorly tuned white balance and overly low saturation of this colour cause the image to appear too cool. As a result, one may get the impression that the displayed content is simply lacking in 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 may appear somewhat washed out. Fortunately, in the Philips menu, we find quite a few functions to improve these aspects, so we immediately proceeded to calibration to see what could be squeezed out of this screen.

After calibration, the television Samsung OLED 48 S90D in film mode looks even better than one could have presumed. The white balance, for both HD and 4K HDR content, has been improved to nearly perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the quality of the image. The colours are more balanced, which translates to a natural representation of details, particularly in scenes requiring a precise colour palette. It is worth adding that this model in the 48' size is equipped with a WOLED panel that has a different characteristic compared to larger sizes and has a smaller coverage of a wide colour gamut, not offering such rich colours as, for example, the 65-inch version, which is fitted with a QD-OLED panel.

The contrast has also undergone significant improvement. The gamma graph after calibration is much closer to the expected line, providing a better balance between the bright and dark parts of the image. The EOTF curve, which before calibration showed issues with overexposed scenes, now displays better results. This effect allows for greater detail preservation in the bright parts of the image, especially in HDR material.

After professional calibration, it is evident that the PUS7000 responds well to image adjustments. In this price range, this is not at all a given. The effects should be evaluated in two scenarios, depending on what content we plan to watch. SDR performs the best. After our adjustments, the picture looks really good. Most colour errors have fallen below level 3, which is the threshold at which distortions usually begin to be visible to the naked eye in measurements. Films, series, sports, and regular television look natural, without unpleasant deviations. If someone mainly watches classic channels or streams in HD quality, the difference after calibration will be noticeable immediately. However, it must be clearly stated that the PUS7000 is still not a television suited for reasonable HDR, and calibration changes very little in this regard. The reason lies in the hardware: the colours remain too unsaturated. The television lacks solutions to expand 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 apparent in reds, which still look pale. This limitation cannot be bypassed with menu settings, as it stems from the design of the backlighting and the panel itself.

The Samsung OLED 48 S90D television performs very well in smoothing tonal transitions. Thanks to the applied technology, the transitions between colours are more fluid and natural. There is also the option to use the noise reduction function, which further smooths tonal transitions, which can be useful in certain situations. However, it is worth remembering that enabling noise reduction can also lead to the smoothing of desired film grain, which in turn can reduce the cinematic atmosphere of the image. For this reason, caution is advised when using this function, as it is better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint and excels at scaling images from lower resolutions. The S90D OLED 48 Samsung television effectively processes lower resolutions, as seen in the visible image. The outline of the model is clear and correct, looking natural and detailed as a result. Moreover, the branches of trees are well replicated, showing no strong jaggedness that could detract from the quality of the image. Thanks to effective scaling, even lower resolution materials look attractive on the screen, satisfying users who prefer a variety of content sources such as regular aerial/cable television.

The PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths out unwanted tonal transitions even at low settings. However, it has a drawback: if applied too aggressively, it can introduce undesirable artifacts on the screen. Therefore, it would be a good idea to experiment with this setting to find a happy medium between a smooth image and detail clarity.

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

The S90D television is equipped with a 120 Hz panel, with the possibility of "overclocking" to 144 Hz with the appropriate PC configuration, ensuring exceptional motion fluidity. For years, Samsung has offered a variety of image sharpness settings on a ten-point scale, allowing users to customise the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there is no sign of any blurring. The pixel response is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The image is incredibly sharp and detailed, even during fast action, making the S90D OLED 48 Samsung television an ideal choice for gamers and sports enthusiasts.

In this respect, 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 is actually the norm, and it is hard to expect anything more. However, the worst part is that the television does not have any features to improve motion smoothness. There is a lack of any supporting systems, both in films and in sports. We must 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, the motion can appear choppy or unclear. We do not have the option to enable any smoothers that would reduce this effect.

The Samsung OLED 48 S90D television is excellently tailored to the needs of gamers, offering four HDMI 2.1 ports that support features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HGIG (HDR Gaming Interest Group). With these technologies, gamers can enjoy smoother gameplay and faster screen responsiveness, significantly enhancing comfort during long gaming sessions. Additionally, the Game Bar feature allows for easy adjustments of settings such as screen ratios, which can be particularly useful in various types of games. For PC users, the television offers an impressive refresh rate of 144Hz, and Nvidia and AMD graphics cards support G-Sync and FreeSync, further improving image fluidity. Although the lack of Dolby Vision support may be a downside, it is worth noting that this technology is not as widely used in games as it is in films. Nevertheless, the S90D still offers excellent features for gamers, making it an outstanding choice for those seeking high-quality visuals and advanced gaming technologies.

Although the PUS7000 is not marketed as a gaming television, it does not perform as poorly in this category as one might expect. While it is true that we won’t find support for 120 Hz refresh rates, which is understandable at this price point, the manufacturer has ensured several important features that genuinely enhance the gaming experience on consoles. The most important of these are the VRR and ALLM technologies. VRR is responsible for synchronising the screen with the number of frames generated by the console. This prevents the image from tearing and keeps it consistent even during sudden drops in frame rate while gaming. In contrast, ALLM is a solution that automatically switches the television to the lowest latency mode as soon as it detects 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 summoned on screen at any time. It allows for a quick preview of the current settings and connection status without interrupting gameplay, which is a very convenient solution.
