Samsung QN900F vs Philips OLED950

QN900F is really a bright TV – it can generate nearly 2000 nits, which is a value that remains unattainable for most models available on the market. But the mere ability to achieve such brightness is not everything – it also matters whether the TV can use it well. And this is not always perfect. Our tests on movie scenes showed that in scenes such as those from Life of Pi or The Meg, the QN900F can truly shine – literally and figuratively. In such moments, its greatest advantage, which is brightness, makes a huge impression. However, in more challenging scenes, the issues begin – similar to assessing contrast. When smaller, bright elements appear on the screen, the TV often struggles with the decision: whether to highlight them at the expense of black levels, or perhaps maintain deep black but tone down the brightness. The result of this is situations where, for example, in the movie Sicario 2, the brightness dropped to just 200 nits, making details barely visible. The dimming algorithms could definitely be better for a TV of this class.

OLED950 is a phenomenal TV for consuming HDR content, which is primarily due to the use of innovative Tandem OLED technology. With this technology, the screen is capable of generating astronomical brightness values, reaching over 2000 nits in movie scenes (on test screens). This is an outstanding result, placing the OLED950 model among the very top displays available on the market. However, it should be noted that there is a specific characteristic of this solution – at moments when full-screen bursts of light appear on the screen, the brightness can drop by as much as half. Nevertheless, it is worth emphasizing that values above 1000 nits on a full screen are still an outstanding result. This allows for HDR images to be displayed exactly as filmmakers would wish, maintaining the dynamics and impact of light scenes.

The use of Tandem OLED technology has also brought measurable benefits in terms of color reproduction, improving elements where traditional WOLED panels have had difficulties compared to QD-OLED competitors. In the case of the OLED950, the color gamut coverage is broader than in classic WOLED panels, reaching nearly 100% of the DCI-P3 space and a solid 82% of the demanding BT.2020 palette. Although these results still do not match the high achievements of QD-OLED panels, the difference diminishes during real-world usage. We cannot deny that in the vast majority of films, colors look simply fantastic on this model – they are saturated, vibrant, and full of depth.

Testing the QN900F in Filmmaker mode, one quickly noticed the characteristic features of the image despite the fact that this mode is designed to reflect the director's vision. The white balance was not perfect – the television had noticeable deficiencies in blue color. This made the entire scene take on a warmer tone, as if someone had applied a subtle filter in shades of yellow and orange. In movies where bright shots dominate – for example, scenes in the snow or in strong daylight – this created a slight warming effect, which does not always convey the director's intent. The second noticeable element was brightness management. The QN900F sometimes managed to brighten the image more than necessary. It looked as if the exposure had been slightly "pulled up," causing the scene to lose its naturalness. Shadows were sometimes too shallow, and contrast was slightly weakened. These are not disqualifying errors, but for a television in this price range, it is evident that Filmmaker mode has not been perfected one hundred percent. This is particularly evident when comparing its image to what was visible after screen calibration.

We tested the OLED950 model in Movie mode. Although it is theoretically the best and most faithful preset on this television, in practice, it proved to be not without flaws. Interestingly, in the unit we tested, the biggest challenge wasn't the white balance itself – although it did have a slight tendency to give the image a pinkish tint. The main problem lay in the way the television managed brightness, both in everyday SDR content and in demanding HDR scenes. Analysis of the gamma chart and EOTF curve leads to one key conclusion: the television excessively highlights brightness in the lower registers. This results in the image appearing less contrasty than the panel technology would allow. 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, so – as always – we proceeded with professional calibration.

After calibration, we were able to eliminate the errors in white balance and adjust them to a level that can be considered acceptable. It's not perfect, but definitely better than the factory settings. Most color errors are now within the deltaE 2–3 range, so in practice they shouldn't be noticeable during everyday viewing. The biggest improvement is seen in how the television manages brightness in SDR content. Shadows and details are no longer flattened, giving the image depth and naturalness. When it comes to 4K HDR materials, colors themselves are no longer an issue, but some imperfections of the Mini-LED technology can still be observed. The QN900F tends to dim the smallest bright elements too much, causing them to sometimes disappear from view. However, it should be added that this is a much better solution than boosting the entire screen, which would spoil the contrast. It's more of a characteristic of this technology than a typical flaw, but it's worth keeping in mind. The effects of calibration are really very good.

As can be seen, the OLED950 transforms into an absolutely phenomenal display after a professional calibration process, which without a shadow of a doubt can be placed in the same category as 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 Color Checker tests and the fidelity of the color palette speak for themselves. We are dealing with an almost perfect device here. A true window to the world, offering top-notch image quality.

If we would like to eliminate non-fluid tonal transitions that can be annoying, for example while watching YouTube, we can use a feature called noise reduction. It works really effectively – it removes the issues with color blending when we set it to Standard level. However, as with most Samsung televisions, this comes with compromises. Although we did not notice that this feature significantly affects the structure of objects in the image, it unfortunately reacts rather aggressively to film grain. Most people will appreciate this effect – the noise is simply removed – but if someone is looking for an image as close as possible to reference settings, then we definitely recommend turning off this option.

As for scaling, which means handling very low-quality content, the QN900F performs really well. On the test screen with the model, the image looked clear, with only slight aliasing that should not bother most viewers. However, it is worth mentioning one issue – the television has problems with so-called overscan, which can cause older content to be slightly cropped. This can manifest itself, for example, with subtitles disappearing from the bottom of the screen.

Upscaling

In terms of image scaling, the proprietary P5 processor performs just as well as in most models from this manufacturer. Lower resolution content takes on a very soft and plastic character. Such a presentation will certainly appeal to many. However, if you prefer sharper contours, you can gently enhance them with the appropriate slider in the TV menu. In this aspect, it's really hard to pick on anything. The image simply looks very good and additionally there is no problem with the phenomenon of overscan.

Smoothing and Distortion Reduction

The tonal transition smoothing feature fares a bit worse. In the settings, we find an option called “Distortion Reduction.” This allows for three levels of processor intervention adjustment. 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 the skin details of actors. On the other hand, the Maximum setting works too aggressively. It removes definitely too many details from the face and background elements or can even take away the film grain. To achieve the optimal effect, it's worth playing around with these settings at home and adjusting them to your preferences. It might seem that the Medium option represents the best compromise here.

There really isn't anything to complain about here – the QN900F looks very good when it comes to motion. Thanks to the 165 Hz panel in 4K, one can confidently say that this TV is suitable for both watching sports and gaming. The motion smoothness feature plays a key role here. It works remarkably well – not only during sports broadcasts, where it can eliminate blurring and image jitter, but also in games, where the animation becomes clearer and smoother. And of course, if someone likes to experiment with movies – they also have that option. At lower settings, there's a slight graininess and filmic character, while at higher settings, it reaches soap opera effect territory. So everyone can adjust the picture to their preferences, and the TV has the power to handle it.

The motion representation in the OLED950 model is virtually perfect. This is typical for screens of this type (OLED 120Hz+), as the matrix shows no blurring at all. Thanks to this, we can enjoy flawless sharpness in practically any conditions. A big part of this is not only due to the specifics of organic technology. Equally important work is done by the smoothing systems implemented by the manufacturer.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.

It is really nice here. The QN900F offers a full set of features that we would expect from a top-tier gaming television – we have VRR, ALLM, Game Bar, and also cloud gaming applications. However, the biggest highlight is the proprietary motion smoothing, which also works in games and – importantly – does not add noticeable delays. This is something we won't find in its other competitors. Unfortunately, there is also something concerning. This year, Samsung has apparently messed something up with its televisions. During the test of the QN900F before its update, it had the HGIG feature, which allowed for perfect adjustment of HDR settings for the console. However, according to our procedures, we always update the equipment to the latest version – to give the manufacturer a chance to fix any shortcomings. And here… it turned out the opposite. After the update, the HGIG feature disappeared from the menu, making the proper configuration of the console for HDR practically impossible. It was supposed to be complete – 165Hz, four HDMI 2.1 ports, a full gaming package… but unfortunately, it turned out to be a little blunder. Such a shame.

OLED950 is almost the perfect TV for gamers. This is not only due to the unique atmosphere that the Ambilight system creates during gameplay. The most important aspect here is the solid hardware support. We find literally everything that one should expect from a modern gaming screen today. 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 ALLM automatic game mode is also included. The device handles any HDR signal effortlessly, 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 graphically attractive on the market, it fully serves its purpose. It displays all the most important signal parameters and offers useful additions. Gamers can take advantage of the mini-map zoom function or add a permanent crosshair on the screen, which can be seen as a small aid in online competition. Adjusting the contrast range also proves useful. It allows for brightening shadows and achieving better visibility of enemies hidden in the dark corners of the map.
