Samsung QN900F vs SAMSUNG OLED S95F (QD-OLED)

QN900F is a seriously bright TV – it can generate nearly 2000 nits, which is a level that remains unattainable for most models on the market. But the ability to achieve such brightness isn’t everything – it also matters whether the TV can make good use of it. And here it’s not always perfect. Our tests on cinematic scenes showed that in scenes like those from Life of Pi or The Meg, the QN900F can really shine – both literally and figuratively. In such moments, its greatest advantage, which is brightness, makes a huge impression. However, in more demanding scenes, things start to get tricky – similar to assessing contrast. When smaller, bright elements appear on the screen, the TV often struggles with the decision of whether to highlight them at the cost of black levels or perhaps maintain deep blacks but tone down the brightness. The result 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, considering the class of this television.

The new generation of QD-OLED panels in Samsung's S95F showcases its full potential, and the brightness results are simply astounding. In test film scenes, such as “Life of Pi” or “Sicario 2”, where smaller light elements appear – stars, the moon, or spotlights – the television managed to achieve over 2000 nits of brightness. This is a result that surpasses even most top Mini-LED models.

The secret lies in the technology itself – instead of a limited number of dimming zones like in Mini-LED televisions, here we have millions of glowing pixels, allowing the television to fully demonstrate its power without technological compromises. Of course, since it is still an organic panel, in scenes that are full-screen and flooded with white – like in the final sequence from The Meg – brightness drops to around 1400 nits. Nevertheless, the result remains excellent and definitely exceeds what any OLEDs, both QD-OLED and WOLED, have offered so far. The colour reproduction is also particularly noteworthy. Thanks to QD-OLED technology, the television achieves almost 100% coverage of the DCI-P3 colour space and around 80% in BT.2020. These values make HDR images not only dazzling in brightness but also stunning in their range of colours.

Testing the QN900F in Filmmaker mode, the distinct characteristics of the image quickly became apparent, despite this mode being designed to reflect the director's vision. The white balance was not perfect – the television had noticeable deficits in blue. This caused the entire scene to take on a warmer tone, as if someone had applied a subtle filter in shades of yellow and orange to the image. In films where bright shots dominate – for example, scenes in the snow or under strong daylight – this gave an impression of a slight warmth that does not always convey the director's intention. The second noticeable element was the management of brightness. The QN900F sometimes brightened the image more than necessary. It looked as if the exposure had been slightly "pushed up," which caused the scene to lose some naturalness. Shadows could be too shallow, and contrast slightly weakened. These are not disqualifying errors, but for a television in this price range, it is clear that the Filmmaker mode has not been perfected one hundred percent. This is particularly noticeable when we compare its image to what was visible after the screen calibration.

The best picture mode straight out of the box is undoubtedly Filmmaker Mode – a mode that Samsung has been using for several years and which is intended to faithfully convey the creators' vision. In SDR content, its implementation is not bad, although some imperfections can be noticed. The image is slightly dimmed, and the screen has a subtle pinkish hue resulting from an excess of red and blue in the white balance. Colour errors remained at a level of 3–4 ΔE units – and for the uninitiated: a value above 3 is the threshold where the average human eye starts to notice differences.

Much bigger problems arise in HDR content, however. Here, the white balance was not as much of an issue – a slight excess of blue did not significantly hinder things. The problem became brightness management. In practice, the TV "blows out" the image too much, causing details in the blacks to completely disappear. The final effect was far from what was expected, and the colour errors in this mode became quite significant. It’s hard to say why such a design decision was made, but it was clear that the factory HDR settings do not allow this TV to showcase its full potential.

After calibration, we managed to reduce 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 colour errors now fall within the deltaE 2–3 range, so in practice, they shouldn't be noticeable during everyday viewing. The biggest improvement is evident in how the television handles brightness in SDR content. Shadows and details are no longer flattened, giving the image depth and naturalness. As for 4K HDR materials – colours themselves are no longer an issue, but one can still notice some imperfections in Mini-LED technology. The QN900F tends to excessively dim the smallest bright elements, causing them to sometimes disappear from view. However, it's worth noting that this is a much better solution than boosting the entire screen, which would ruin the contrast. This is more of a characteristic of the technology rather than a typical flaw, but it's worth keeping in mind. The effects of the calibration are really very good.

After calibration, it was possible to make subtle adjustments to the white balance and significantly improve the image characteristics. In SDR content, the quality has become practically reference-level – most colour errors have dropped below a ΔE value of 1, which is the level at which the human eye can no longer perceive differences. This is a result that places the S95F among the absolute top TV models available on the market.

In HDR material, calibration also brought a significant improvement. The tendency of the TV to blow out the image was managed, as confirmed by the analysis of the EOTF curve. There is still a slight tendency to brighten the entire scene or occasional loss of detail in the blacks, but this does not significantly affect the overall perception. After calibration, the S95F shows its full potential and can be regarded as one of the best TVs on the market!

If we want to get rid of awkward tonal transitions that can be annoying, for example, while watching YouTube, we can use a feature called noise reduction. It works really effectively – it eliminates issues with colour blending when set to Standard level. However, as with most Samsung TVs, this comes with some compromises. Although we didn't notice this feature having a significant impact on the structure of objects in the image, it unfortunately reacts quite aggressively to film grain. Most people will likely appreciate this effect – the noise is simply removed – but if someone is looking for an image as close as possible to reference settings, we definitely recommend turning this option off.

When it comes to upscaling, or dealing with very low-quality content, the QN900F performs really well. On the test pattern with a model, the image looked clear, with only slight jaggedness that shouldn't bother most viewers. However, it’s worth mentioning one issue – the TV sometimes struggles with so-called overscan, which means older content may be slightly cut off. This can manifest, for example, with disappearing subtitles at the bottom of the screen.

Samsung S95F offers a noise reduction feature that smooths tonal transitions. It works very effectively, but in practice, it can be too aggressive. Materials of lower quality – e.g. older recordings or videos from YouTube – become soft and plastic when it is enabled, resembling an image digitally smoothed in graphic software. Unfortunately, the natural film grain, which often adds authenticity to the image, disappears in the process. Fortunately, the television does not lose too much fine detail, e.g. in skin textures or environmental elements. Therefore, this feature is best used judiciously – depending on preferences, one can achieve a smooth but less natural image or one that is truer to the original. In our opinion, the most universal choice is the “Standard” setting.

Image scaling performs significantly better. The television handles lower resolution materials well – even 576p content looks quite decent, though slight blockiness can be observed. Overall, the effect is very good, although it slightly trails behind what Sony Bravia 8 (II) or LG G5 can achieve. It’s also worth mentioning a small imperfection of the S95F – in older materials, overscan may occur, causing a slight trimming of the left edge of the image.

There’s really nothing to nitpick here – the QN900F looks great when it comes to motion. Thanks to its 165 Hz panel in 4K, you can confidently say that this TV is suited for both watching sports and gaming. The motion smoother plays a key role here. It works brilliantly – not just with sports broadcasts, where it can eliminate blurring and image judder, but also in games, where animation becomes clearer and more fluid. And of course, if someone likes to experiment with movies – they have that option as well. At lower settings, you can see a slight graininess and a filmic quality, while higher settings introduce a soap opera effect. So everyone can tailor the picture to their preferences, and the TV has the power to handle it.

The Samsung S95F excels in motion fluidity, presenting phenomenal performance. The panel operates at a native resolution of 4K with a refresh rate of up to 165 Hz, and when combined with QD-OLED organic technology, it delivers incredible results. Sports and games look sensational – the picture is fast, dynamic, and very natural. Additionally, the built-in motion smoother and blur reduction system allow you to customise the character of the image to your own preferences. You can opt for a more 'framey' effect with visible film texture or a smooth, cinematic spectacle. Every viewer will find a setting that suits them.

It's really good here. The QN900F offers a full set of features that we would expect from a top-notch gaming TV – we have VRR, ALLM, Game Bar, as well as cloud gaming apps. However, the biggest standout is its proprietary motion smoother, which also works in games and – importantly – does not add noticeable input lag. This is something we won't find in other competitors.

Unfortunately, there is also something concerning. This year, Samsung has clearly messed up something with its TVs. During the testing of the QN900F before its update, it had the HGIG feature, which allowed for perfect adjustment of HDR settings for consoles. However, according to our procedures, we always update the hardware to the latest version – to give the manufacturer a chance to fix any issues. And here… it went the other way.

After the update, the HGIG feature disappeared from the menu, making 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 mishap. What a shame.

The same advantages of low motion blur and excellent motion fluidity characteristic of OLED panels are just the beginning, as the Samsung S95F has been designed with gamers in mind. The manufacturer has equipped it with four HDMI 2.1 ports – though limited to a bandwidth of 40 Gb/s, in practice, this has no impact on compatibility with consoles or PCs. We get a full package of gaming features: variable refresh rate (VRR), automatic game mode (ALLM), as well as a very well-implemented HGiG standard, ensuring that HDR titles look as the creators intended. This is complemented by Game Bar – a clear settings hub, where with one motion, we can preview and change all key image parameters. The proprietary motion smoother Game Motion Plus also deserves praise, as it can smooth out animation, which is especially useful in productions running at 60 frames, where stability is not always exemplary. While there is no support for Dolby Vision in games, it’s hard to consider this a serious drawback – Samsung compensates with other solutions. This is one of the best, if not the best, gaming TVs available on the market today.
