Samsung S85F OLED vs Samsung QN90F / QN92F

As an OLED, the Samsung S85F can shine – literally. In favourable conditions, it can generate brightness exceeding 750 nits. This is significant because most films are created with displays aiming for around 1000 nits. In practice, this means that in scenes with moderately large, bright elements, the picture can look absolutely stunning. However, it's not always so rosy. When an enormous amount of light appears on the screen – whether it's an expansive, bright background or an entire frame filled with white – the S85F must tone it down. Brightness can drop by even four times in such scenes. This limitation is well-known to anyone familiar with OLEDs in this price segment, so we don't view it as a particular fail. However, something that deserves praise is what sets this model apart from the competition – colour gamut coverage. Thanks to the QD-OLED panel, our colour meter indicated values exceeding 100% coverage of DCI-P3 and an impressive 86% for the ultra-wide BT.2020 palette. Such results are hard to find even in televisions that cost several times more.

Samsung QN90F can really shine with brightness. In our measurements, it reached even over 2200 nits, which directly translates to the viewing experience. In practice, this means that when a very bright scene appears in a film – for example, a sunrise in The Meg – the screen looks as if natural light is actually shining on us. This isn't just a number from a table, but a real sense of image intensity! However, the TV can't always deliver its full power. With smaller details, such as spotlights or lamps, brightness drops to 500–700 nits. This is a deliberate decision by the algorithms – by doing this, the contrast between large and small elements is better controlled, and the image doesn't lose balance. Importantly, this is still a huge improvement compared to last year's QN90D, where similar details were almost invisible, shining at just 200 nits. Here, the HDR effect is much more cohesive and credible. The only downside is the colours. The coverage of the DCI-P3 spectrum has plateaued at 91%, which can be considered a rather average result in this price range.

Samsung, as befits a manufacturer with ambitions, has equipped the S85F with a mode called Filmmaker. Its task is simple: to make the colours on the newly purchased television as faithful as possible to what the director intended to show us. Sounds great… but, as is often the case, a theory that sounds wonderful doesn’t always translate into perfect practice.

In the tested unit, it quickly became apparent that the image – due to an excess of blue and red – looked as if someone had gone a bit overboard with the saturation. As a result, there were quite significant colour errors, particularly in 4K content. On top of that, there was an issue with brightness – the S85F could brighten most scenes more than it should, stripping them of the intended mood.

Fortunately, Samsung televisions, including the S85F, offer an impressive number of settings for advanced calibrators. This means that we could see what this panel is really capable of when it gets into the right hands.

The colour reproduction in the QN90F was tested in Filmmaker mode and, as is usually the case with Samsung TVs, this mode proves to be the best starting point straight out of the box. However, this does not mean that we are dealing with an image free of flaws. The white balance in SDR and HDR content was surprisingly good – colours didn't drift in any direction and even in its factory settings it looked solid. However, a problem arose with the gamma and EOTF curves, which determine how the TV manages brightness. Here, the QN90F significantly brightened the entire image, causing the black levels and colours to lose their intensity, and the overall effect resembled that of an applied milky filter. Fortunately, Samsung, unlike many competitors in the miniLED world, provides users with plenty of tools to control settings that we won't find in other manufacturers, such as Chinese brands. Therefore, we decided to see if we could squeeze the full potential out of the QN90F because we know that such a high series is capable of much more.

Thanks to the huge number of settings in the menu, we managed to bring the S85F almost to perfection. White balance in SDR content? Literally perfect – deviations do not exceed a value of "1". So we can confidently say that in materials with not too high dynamics, we have an image that's close to reference.

In HDR content, minor issues appeared, but they don't have much significance in practice – most errors fall below the threshold of perception, which is a value of "3". We also managed to tame the S85F when it comes to brightness management – the EOTF curve, even in films, holds nearly perfect straight line. This is one of those cases where after calibration, you can comfortably forget about the settings and simply watch movies and series at the highest level.

After our adjustment of the settings, the QN90F showed what it’s really capable of – and we have to admit, it’s one of the best images we’ve seen on a miniLED screen this year. As we mentioned earlier, the white balance wasn’t a big issue even in the factory settings, but it was only after gamma calibration that we were able to get close to reference values. The same goes for HDR content, where the EOTF curve post-adjustment presents mature and consistent results. Indeed, in some films, you can notice that the smallest elements of the image are slightly brightened, and with a limited number of local dimming zones, there's still a risk of halo effect. However, it’s important to remember that such phenomena are characteristic of all miniLED TVs and it’s difficult to expect miracles even from the QN90F. The most important thing is that after calibration, the television displays an image that confidently competes with many OLED screens available on the market in terms of expressing the director's vision.

The tone transition smoothing function in the S85F works really effectively – it can completely eliminate the problem of visible banding in very poor quality material, such as from YouTube. Unfortunately, even the lowest level of this option comes with compromises. The noise reduction is so aggressive that it can smooth out film grain, which many of us consider to be an element of the cinematic atmosphere. At the “Standard” level, we didn’t notice this function removing anything significant from the image, so we can recommend this setting. On the other hand, the “High” level is a different story – it can smooth out not just noise, but also small, desirable details like, for example, the texture of objects.

When it comes to image scaling, the S85F performs very well. The material looks sharp, and the only slight imperfection is the barely noticeable aliasing of edges. And there’s the ongoing issue with Samsung televisions – overscan. This can cause some scenes to be slightly cropped, which is worth noting when watching very old content.

QN90F handles upscaling very well. Materials in lower resolutions, even SD, are enhanced to a clear and sharp image, where a lot of background detail can be seen. This is a big advantage, as the TV makes older content or everyday television look significantly better than on most budget screens. However, the issue of overscan remains, which is the cropping of the screen edges that cannot be turned off on Samsungs. This can cause some subtitles on the screen to disappear or Auntie's face from the wedding on a VHS tape to be slightly cropped. 😉

The digital image processing also performs well. In the menu, we find a feature called "noise reduction," which can smooth tonal transitions and improve the viewing of lower quality materials, such as those from YouTube. In the medium setting, the effect is most beneficial – it doesn't heavily interfere with details while simultaneously eliminating the problem of "banding" in colours. However, it's worth noting that the feature can be quite aggressive and removes natural film grain in older movies, so it's best to use it sparingly.

S85F is an incredibly fast television – and that’s not just empty hype. Thanks to the 120 Hz OLED panel, dynamic scenes, whether in games or while watching a live match, look just as they should – smooth, sharp, and without the feeling that something is "slipping" out of frame. The lightning-fast pixel response time, typical of OLEDs, plays a big role here. Transitions between frames are virtually instantaneous, and the image remains clear even during the fastest camera movements. A ball flying across half the field? A car speeding in a chase scene? Everything here is clear and free of the typical "trail" associated with LCDs.

This is exactly what we expect from a good OLED – zero compromises when it comes to motion smoothness. The S85F gives the impression that regardless of the pace of action, we can focus on what’s happening on the screen, rather than on the imperfections of the image.

QN90F has been equipped with a panel that has a maximum refresh rate of 165 Hz, and while this advantage will mainly be appreciated by PC gamers, it’s still worth highlighting. In movies or sports broadcasts, we are limited to the classic 120 Hz, but this is not a cause for concern. In practice, the additional motion smoother is more significant here. Thanks to the "Motion Clarity" setting, we can adjust the picture to our own preferences. The blur reduction option is responsible for fluidity and ghosting in sports. Meanwhile, the "judder reduction" function improves motion fluidity in productions recorded at 24 frames, namely films and series. If we set it high, the film looks smoother and more fluid than it was actually shot. Lower values, on the other hand, preserve its cinematic "rawness" with the visible film frame.

[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.

S85F has practically everything on board to become the dream screen for gaming. Four full HDMI 2.1 ports with a bandwidth of 48 Gb/s, support for VRR, ALLM, a super-detailed Game Bar that clearly shows all parameters – plus a gem in the form of Game Motion Plus. This motion smoother makes animation in games more enjoyable, while input lag increases slightly. It's a rare combination, and that’s a big plus for Samsung. Perhaps Samsung will fix this in the next update – and we have high hopes for that. Because if HGiG comes back, the S85F will become nearly the perfect TV for gamers.

QN90F has almost everything to become the perfect TV for gamers. Things like four HDMI ports, VRR, ALLM, or refresh rates reaching up to 165 Hz need no reminder. The Game Motion Plus mode deserves a big thumbs up, which is the proprietary motion smoothing technology for games. With it, you can add a few 'artificial' frames and make the image generated from the console look smoother than it should. This is a very unique solution in the world of TVs – competing systems usually do not offer this – and that's why Samsung has had a strong selling point among gamers for years, even despite the lack of support for the still niche Dolby Vision in games.

[UPDATE] We have updated our tests of Samsung TVs from the 2025 range due to the release of firmware version 1131, which restored the crucial HGiG feature for gamers.

So why do we refer to it as an 'almost' perfect screen? Unfortunately, just like in recent Samsung models, we've noticed a problem with the lack of HGiG functionality. This is a solution that allows the TV to leave control over tone mapping to the console, so that games look exactly as the creators intended. Worse still, this feature was previously present and disappeared after software updates. Instead of minor fixes, we got a step backward. It's a shame, because if it weren't for this lack, the QN90F could have been a truly ideal choice for gamers in the miniLED category.
