Samsung QN900F vs Samsung OLED S95H (S99H) (QD-OLED)

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.

When it comes to brightness alone, the S99H is an astronomically bright TV. Its peak brightness in movie scenes can exceed 2800 nits! Regardless of the scene, you can count on powerful HDR effects that practically blind you, and that's exactly what we expect from a top-tier screen. It's inherent to OLED panels that in very bright, full-screen shots they won't sustain as high a brightness as they do with small highlights, but the results are still excellent. In a bright scene from the film The Meg, the sun still exceeded 2200 nits. That means the S99H was able to maintain higher brightness than most Mini LED screens on the market. In terms of brightness, the S99H is currently the best OLED TV we've tested.

Color gamut coverage

The S99H also handles color exceptionally well, which is a direct result of the QD-OLED panel used here. Regardless of the test scenario, whether synthetic test patterns or measurements with film material in the background, the results stayed at a very high level. The S99H easily covers almost 100% of the DCI-P3 gamut, and for the most demanding color space it reaches nearly 90% of BT.2020. That's top-tier performance on the market. These results match what we saw in the new SQD-Mini-LED screens, and in real movie scenes they even outperform RGB Mini LED displays.

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.

Samsung offers a whole host of picture modes and features, but as usual we recommend choosing Filmmaker Mode, especially if you want the most faithful rendering of the creators' intent. Out of the box the TV is tuned very well, though it has minor shortcomings. This mainly concerns a slight drift in white balance in SDR content and a slightly low gamma. As a result, in a darker room the image can be a bit too bright relative to the reference gamma of 2.4, which is the standard for watching films with the lights off. These are of course small issues, since overall color reproduction remains very good and the errors in ColorChecker measurements are small. However, we know that from a screen of the S99H's class you can and should expect even more, so we had it professionally calibrated.

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.

After professional calibration, FILMMAKER mode looks virtually perfect. Because Samsung offers a rich set of advanced calibration features, we were able to tune the colors to an almost perfect level. Most importantly, we were able to even out the white balance and the gamma curve, which resulted in noticeably better contrast and a more natural image dimensionality. With a profile prepared like this, there's really nothing to nitpick or call a flaw. After calibration, the S99H is capable of delivering an essentially reference-quality image.

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.

The proprietary Samsung NQ4 Gen3 processor handles upscaling and digital image processing. It does a very good job scaling lower-resolution material to 4K. The picture is sharp but doesn't look artificial or overly sharpened. The only fairly specific drawback appears with very old footage shot at 480p or lower. In those cases the TV can slightly crop the edges of the image.

The processor also copes quite well with artifacts visible in low-bitrate material, for example heavily compressed YouTube videos. The noise reduction feature effectively smooths the image and reduces posterization, but it works rather aggressively. It can remove not only unwanted artifacts but also some fine details and even natural film grain. We, wanting to preserve maximum fidelity to the source material, chose not to use it. However, if someone values a clean, as-smooth-as-possible image over keeping every detail, it can be useful.

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.

Another major advantage of OLED panels is excellent motion reproduction. Thanks to the pixels' near instant response time, the Samsung S99H practically produces no smearing. Fast-moving objects don't show noticeable halos or trailing artifacts, so the TV performs very well for both watching sports and gaming. One quirk of OLED screens compared with LCDs is how they render low frame rate material. With very slow camera movement the image can appear noticeably more stuttery. This can be quite effectively mitigated using a frame interpolation system. Samsung lets you adjust judder reduction and blur reduction separately, making it easy to find a compromise between smoother motion and preserving the cinematic character of the content.

[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.

Samsung S99H is also an excellent TV for gamers. It offers almost every useful feature... well, maybe except the obvious lack of Dolby Vision for Xbox consoles. It's equipped with four fully functional HDMI 2.1 ports with the full 48 Gbps bandwidth. Thanks to that we can easily use frame-rate synchronization VRR and automatic low-latency mode (ALLM). This year Samsung also has no issues with proper HGiG support, so HDR setup on a console is quick and without unnecessary complications. Samsung is also known for interesting extras in its TVs. In the Game Bar menu you'll find options to add an on-screen crosshair, enlarge the mini-map, or change the aspect ratio of the displayed image (PC).

Particularly noteworthy is Samsung's feature: Game Motion Plus. It's Samsung's proprietary motion-smoothing system that uses interpolation to increase smoothness in games. Input lag then rises to around 40 to 50 ms (depending on the strength of the setting), which is an excellent result compared to the competition. The system makes gameplay noticeably smoother. So if someone has their eye on a demanding game (e.g., GTA 6 😉) that runs at only 30 frames per second on console, the S99H can display it much more smoothly than competing models.
