Samsung S90F QD-OLED vs Philips OLED950

The biggest difference between the 65-inch S90F and the other versions is brightness. The QD-OLED panel can reach up to 1700 nits in laboratory tests, which is over 500 nits more than the variant with a WOLED matrix. This translates to a decidedly stronger and more engaging HDR effect. In most scenes, bright parts of the image look fantastic, and we must admit that we were positively surprised, as we expected results more similar to the WOLED version, but we got an effect that makes a great impression even in films. Just like with every OLED, there are moments when the panel needs to limit its brightness a bit. This mainly refers to full-screen, very demanding scenes – for example, in the last test frame from the film "The Meg," the brightness drops to around 800 nits. However, it is hard to consider this a disadvantage, as it is still an excellent result, unprecedented in OLED televisions in this price range. Everything suggests that the 65-inch S90F could be one of the best choices this year for those looking for a strong OLED at a reasonable price. Another advantage of the QD-OLED matrix in HDR content is its colour gamut coverage. Thanks to quantum dots, the television achieves almost a full 100% of the DCI-P3 colour space and nearly 90% of the BT.2020 colour space. These values place it alongside much more expensive models and make it exceptional in its class.

The OLED950 is a phenomenal television for consuming content in HDR format, primarily thanks to the innovative Tandem OLED panel. With this technology, the screen can generate astronomical brightness levels, reaching over 2000 nits in film scenes (on test patterns). This is an exceptional result that places the OLED950 among the world’s top displays available on the market. However, it is important to note a specific characteristic of this solution – at moments when full-screen bursts of light appear on the screen, brightness can drop by as much as half. It is worth emphasising, though, that values above 1000 nits on a full screen are still an outstanding result. This allows for the HDR image to be displayed exactly as filmmakers would wish, maintaining the dynamics and impact of bright scenes.

The use of the Tandem OLED panel has also brought tangible benefits in terms of colour reproduction, improving elements that traditional WOLED panels struggled with compared to their QD-OLED competition. For the OLED950, the colour gamut coverage is broader than in classic WOLED panels, reaching nearly 100% of the DCI-P3 colour space and a solid 82% of the demanding BT.2020 palette. Although these results still do not match the high standards of QD-OLED panels, the difference diminishes during real-world use. We cannot deny that in the vast majority of films, colours look simply fantastic on this model – they are saturated, vibrant, and full of depth.

Samsung S90F, like most modern televisions, offers several picture modes, but in line with our tradition, we tested it in the most important one, which is Filmmaker. This setting makes the image look much more natural than in the default, often overly saturated modes. It is neither excessively vivid nor artificially subdued – just closer to what one should actually see. However, this does not mean it is perfect. The S90F had noticeable shortcomings in white balance, mainly in the blue range, which gave a slightly yellowish filter effect on most scenes. One might argue that it looks more "filmic" because it is warmer, but let’s not kid ourselves – George Lucas didn't shoot Star Wars in sepia 😉 (a comparison with the scene can be found, as always, below). In HDR materials, there was also an issue with brightness management. The EOTF curve clearly showed that the television brightens the picture more than it should, leading to some effects appearing too intense and deviating from the reference. Fortunately, a large part of these shortcomings can be eliminated through professional calibration – we will discuss the effects of this procedure further on in the test.

We tested the OLED950 model in Film mode. Although it is theoretically the best and most faithful preset on this television, in practice it proved not to be free from flaws. Interestingly, in the unit we tested, the biggest challenge was not the white balance itself – although it did show a slight tendency to give the image a pinkish hue. The main issue lay in the way the television managed brightness, both in everyday SDR content and in demanding HDR scenes. The analysis of the gamma graph and the EOTF curve leads to one key conclusion: the television excessively exposes brightness in the lower registers. This results in the image appearing less contrasty than the panel technology allows. Details in dark areas that should remain perfectly black (characteristic of "OLED black") are simply unnecessarily highlighted and brightened. Fortunately, these errors can be corrected using the appropriate tools, which is why – as always – we proceeded with professional calibration.

Calibration quickly revealed that the S90F has a significant margin of capability. The image in SDR immediately gained a natural quality – classic films no longer looked as if someone had applied a yellowish filter to them, and the colours regained their proper character. It is a return to the atmosphere of the original, without the impression that someone tried to "age" it forcefully. In HDR content, the difference was even more pronounced. The EOTF curve was managed almost to a reference level, and any deviations are so subtle that most viewers won't even notice them. In practice, the S90F shows an image very close to perfection after calibration. Compared to the WOLED version, it performs even better – mainly due to the wider colour gamut coverage, which makes the colours appear fuller and more intense.

As can be seen, the OLED950, after a professional calibration process, transforms into an absolutely phenomenal display that, without a shadow of a doubt, can be placed alongside the best televisions currently available in the world. This equipment only needed a professional touch to show its full potential and eliminate factory shortcomings. The minimal errors in reproduction in the Color Checker tests and the fidelity of the colour palette speak for themselves. We are dealing with an almost perfect device here. A true window to the world, offering image quality of the highest order.

The S90F performs really well here, although there are some comments that recur with most Samsung televisions. The noise reduction feature can effectively smooth out unwanted colour transitions in poorer materials, such as television or YouTube, making them simply look better. However, it should be noted that it operates quite aggressively and can also soften elements we wouldn't want to touch, like facial details. Therefore, if we want to use it, it’s best to set it to 'medium' and be aware of the compromise it entails. The upscaling itself is at a high level – low-quality materials are upscaled towards a 4K-like image. The only caveat is that the S90F can still struggle with so-called overscan, meaning it slightly trims edges with very poor materials like 576p and lower.

Upscaling

In terms of the image upscaling, the proprietary P5 processor performs just as well as in most models from this manufacturer. Low-resolution content takes on a very soft and plastic character. This kind of presentation will certainly appeal to many people. However, if you prefer sharper contours, you can lightly enhance them with the appropriate slider in the television's menu. It's really hard to find fault in this aspect. The image simply looks very good and additionally there is no issue with the phenomenon of overscan.

Smoothing and Distortion Reduction

The function for smoothing tonal transitions performs somewhat worse. In the settings, we find an option called "Distortion Reduction." This allows for three levels of adjustment of the processor's interference. Unfortunately, the Minimum setting works poorly and the smoothing effects are negligible. The Medium level gives a decent result, but it also starts to smooth out actors' skin details. On the other hand, the Maximum setting works too aggressively. It definitely removes too much detail from the faces and background elements, and can even take away the film grain. To achieve the optimal effect, it's worth experimenting with these settings at home and adjusting them to your preference. It may seem that the Medium option is the best compromise here.

S90F is an OLED with a refresh rate of 144 Hz, but in practice, it primarily indicates how it performs at 120 Hz, as this frequency is most significant when watching sports. The QD-OLED panel is no different in this regard from WOLED panels – the response of the pixels is nearly instantaneous, so motion is rendered with surgical precision. The result is predictable. The image is virtually devoid of motion blur, making gaming on consoles, matches, or other sports broadcasts incredibly enjoyable on the S90F.

Fans of films and series have not been overlooked either. Like every Samsung television with a refresh rate of 120 Hz and above, the S90F features a proprietary motion smoothing technology called "Image Clarity." Here, we find two sliders – blur reduction and judder reduction – which allow for improved fluidity of materials recorded at 24 frames and tailoring the effect to personal preferences.

The motion reproduction in the OLED950 model is virtually perfect. This is typical for screens of this type (OLED 120Hz+), as the panel shows no blurring at all. This allows us to enjoy perfect sharpness in practically any conditions. Much of this is thanks not only to the specifics of organic technology. Equally important work is done by the smoothing systems implemented by the manufacturer.

The S90F is a television that truly brings a lot of joy when gaming. To start, we have four full-fledged HDMI 2.1 ports, which means you can connect all consoles and PCs without worrying about which device has priority. This is a convenient and practical solution that is by no means a given with other manufacturers. Additionally, there are key features such as automatic game mode (ALLM), which automatically switches the screen to low-latency settings, and VRR frame synchronization that operates in a wide range from 48 to 144 Hz. As a result, the picture remains smooth regardless of whether we're playing fast-paced online shooters or more leisurely narrative titles. The Game Bar also deserves a mention – a panel that allows quick access to several useful additions. For example, you can enable an additional crosshair in the centre of the screen, enlarge the minimap, or, in the case of PC, change the aspect ratio. Lastly, there is also the unique Game Motion Plus mode from Samsung. Its purpose is to smooth out older or poorly optimized titles, and it actually works pretty well. Thanks to this mode, even less polished games can look better and provide a more enjoyable gaming experience than on other televisions that theoretically offer the same technical specifications.

The OLED950 is nearly the perfect television for gamers. This is not only due to the unique atmosphere created by the Ambilight system during gameplay. The most important aspect here is the robust hardware support. You will find literally everything you should expect from a modern gaming display. The manufacturer has implemented two HDMI 2.1 ports with full bandwidth of 48 Gb/s. This gives us access to gaming in 4K resolution at 120 frames per second. Of course, support for VRR technology and the automatic ALLM game mode is also included. The device handles any HDR signal without difficulty, whether we are using Dolby Vision or the HGiG standard.

Access to all settings is available from one place thanks to the special Game Bar overlay. Although this interface may not be the most visually appealing on the market, it fully accomplishes its purpose. It displays all the important signal parameters and offers useful extras. Gamers can take advantage of the minimap zoom feature or add a permanent crosshair on the screen, which can be seen as a small aid in online competition. The contrast range adjustment also proves to be useful, as it allows you to brighten shadows and gain better visibility of enemies hidden in dark corners of the map.
