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

The Samsung S90D demonstrates impressive brightness performance in the tested film scenes, surpassing the 1000 nits mark in the first four shots—an outstanding result for an OLED display. In the final shot, which features a fullscreen flash of sunlight, the brightness dips to around 500 nits. While this is a decrease, it remains within a very good range, ensuring visibility and detail retention even in bright scenes.

Another key highlight of the Samsung S90D is its remarkable colour coverage, achieving 98% of the DCI-P3 colour space. This means the TV can reproduce an exceptionally wide range of colours, contributing to vivid and lifelike images that are particularly beneficial for films, high-quality video, and HDR content. The high colour accuracy and impressive brightness capabilities, makes the S90D an ideal choice for users seeking premium image quality across various lighting environments, whether in darker rooms or bright, sunlit spaces.

Unfortunately, the PUS7000 is not suitable for watching HDR content. This screen is simply too dark. A brightness level of 200 nits is not enough to correctly display such a format. Even if a HDR signal message appears on the screen, the image will resemble a regular SDR recording. Therefore, it's better to stick with the latter format to avoid issues in displaying bright scenes, which you can read about below. The situation is not improved by the fact that this is a classic LCD model without additional layers to enhance colors, such as QLED or PFS. As a result, colors 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 was tested in Filmmaker mode, which provides good colour reproduction, albeit with some imperfections that may be noticeable to more discerning users. This mode might appear overly warm, and those switching from Standard mode could find the change somewhat jarring. It is important to note that this issue stems from suboptimal settings, such as the white balance, rather than the Filmmaker mode.

In both SDR and HDR content, the device shows a drop in blue tones, resulting in colours appearing warmer than intended. In practice, this means that certain shades, such as sky blue or skin tones, may seem less natural, with a slight pink or yellow tint. The Colour Checker test confirms these deviations, indicating a shift towards warmer hues. In SDR content, the gamma chart reveals slight inconsistencies that make the image appear marginally darker, particularly in shadowed areas, which may obscure finer details in darker scenes.

In 4K HDR content, the EOTF curve exceeds the recommended level, leading to an overly bright display in some parts of the image, which can cause highlights to appear blown out. Overall, the Samsung S90D delivers a solid image straight out of the box, but for the best performance, further calibration is advised, especially with more demanding content.

We tested the television in movie mode, which theoretically should provide the best and most natural colors. And indeed, this mode is quite correct; however, after connecting the calibration equipment, its biggest flaw became apparent. The PUS7000 has significant deficiencies in displaying red. Poorly tuned white balance and too low saturation of this color cause the image to appear too cool. As a result, one might get the impression that the displayed content is simply lacking in vibrant colors. The situation is exacerbated 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, the Philips menu offers many functions to improve these aspects, so we immediately proceeded to calibration to see what could be squeezed out of this screen.

After calibration, the Samsung S90D in movie mode exceeds expectations. The white balance for HD and 4K HDR content has been refined to near perfection. While minor imperfections remain, they are so subtle that they don’t significantly impact the overall image quality. The colours are now more balanced, resulting in a natural reproduction of details, particularly in scenes requiring an accurate colour palette. It’s important to note that this model, in this size, uses a WOLED panel, which has a smaller wide colour gamut coverage and doesn't deliver the same vibrant colours as the 65-inch version with its QD-OLED panel.

The contrast has also seen notable improvements. Following calibration, the gamma curve now closely aligns with the expected line, achieving a better balance between the bright and dark areas of the image. The EOTF curve, which previously exhibited issues with overexposed scenes, now produces more accurate results, allowing for improved detail retention in the brighter parts of the image, especially in HDR content.

After professional calibration, it is clear that the PUS7000 responds well to image adjustments. In this price range, this is not a given. The effects should be assessed in two scenarios, depending on what content we plan to watch. SDR performs the best. After our corrections, the image looks really good. Most color errors fell below level 3, which is the threshold at which distortions typically become visible to the naked eye in measurements. Movies, series, sports, and regular television present themselves naturally, without unpleasant deviations. If someone primarily watches classic channels or streaming in HD quality, the difference after calibration will be noticeable immediately. However, it must be made clear that the PUS7000 is still not a television suitable for sensible HDR, and calibration does not change much here. The reason lies in the hardware: colors remain too undersaturated. The television lacks solutions that expand the color gamut, such as PFS filters or a quantum dot layer, so the panel simply cannot show the intense colors required by HDR. This is most evident in reds, which still look pale. This limitation cannot be bypassed with menu settings, as it results from the design of the backlighting and the panel itself.

The S90D TV handles tonal transitions exceptionally well. Thanks to advanced technology, the transitions between colours are smooth and natural. The noise reduction function can further enhance the smoothness of tonal shifts, which is particularly useful in certain situations. However, it's important to note that enabling noise reduction can also blur the natural film grain, diminishing the cinematic quality of the image. For this reason, it’s advisable to use this function with caution, as preserving the natural grain can enhance the character and authenticity of the content being watched.

As always, Samsung excels in image scaling from lower resolutions. The S90D effectively processes lower-resolution content, delivering a clear and accurate picture. The model’s outline is crisp, ensuring the image looks natural and detailed. Even the finer details, such as tree branches, are well-rendered without visible jagged edges that could degrade image quality. Thanks to its effective scaling, the S90D ensures that even lower-resolution content looks appealing, satisfying users who enjoy a wide range of content sources, such as regular broadcast or cable TV.

The PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths out unwanted tonal transitions even at a low setting. However, it has a flaw: if the action is too aggressive, it can introduce undesirable artifacts on the screen. It’s a good idea to experiment with this setting to find the sweet spot between a smooth image and detail clarity.

The upscaling, which is the enhancement of lower quality materials to 4K, is adequate. The image after processing is very "soft," which is typical for almost all Philips televisions. 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 to achieve a more pronounced effect.

The Samsung S90D television features a 120 Hz panel, with the option to "overclock" to 144 Hz when connected to a compatible PC, offering exceptional motion smoothness. Samsung has long provided a range of image sharpness settings on a ten-point scale, allowing users to tailor the display to their preferences. In the UFO test, the OLED panel shows no signs of blurring, with pixel response instantaneous and effectively capturing dynamic movements. OLED technology is renowned for its performance in this regard, making it one of the best options on the market. The image remains incredibly sharp and detailed, even during fast-paced action, making the S90D an excellent choice for gamers and sports enthusiasts alike.

In this regard, we don't really have any 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 standard, and it's hard to expect more. However, the worst part is that the TV does not have any motion smoothing features. There are no supporting systems for either movies or sports. We have to accept that the image on the PUS7000 is processed "raw." This means that during dynamic scenes or fast camera movements, the motion may appear choppy or unclear. We have no way to enable any smoother that would soften this effect.

The Samsung S90D is an ideal choice for gamers, featuring four HDMI 2.1 ports that support key gaming technologies such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). These features ensure smoother and more responsive gameplay, greatly enhancing performance during intense gaming sessions. The TV also includes a dedicated Game Bar, which makes managing game settings easy. This functionality allows users to quickly adjust parameters like the aspect ratio offering flexibility for different games and gameplay styles. Customising preferences is straightforward, further enhancing the convenience and enjoyment of gaming.

For PC users, the TV impresses by supporting a refresh rate of 144Hz when connected to a computer. Users with Nvidia or AMD graphics cards can also use G-Sync and FreeSync for a smoother gaming experience. However, it’s important to note that the TV does not support Dolby Vision, which may be a drawback for some. That said, Dolby Vision is not as widely adopted in gaming as in film, so this may not be a significant concern for most gamers. Overall, the S90D offers exceptional features for gamers, making it an excellent choice for those seeking outstanding image quality and modern technological solutions.

Although the PUS7000 is not marketed as a gaming TV, it does not perform as poorly in this category as one might expect. While there is no support for 120 Hz refresh rates, which is understandable at this price point, the manufacturer has included several important features that genuinely improve the comfort of playing on a console. The most significant of these are VRR and ALLM technologies. VRR is responsible for synchronizing the screen with the number of frames generated by the console. This prevents the image from "tearing" and keeps it consistent even during sudden frame drops in the game. In turn, ALLM is a solution that automatically switches the TV to the lowest latency mode right after detecting a signal from the console. All of 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 overview of current settings and connection status without interrupting gameplay, which is a very convenient solution.
