Samsung S85F OLED vs Samsung R85H / R86H

For an OLED, the Samsung S85F can truly shine – literally. Under favourable conditions, it is capable of generating brightness exceeding 750 nits. This is hugely significant, as most films are created with displays reaching around 1000 nits in mind. In practice, this means that in scenes with moderately large, bright elements, the image can look simply fantastic. However, it's not always so rosy. When there is a huge amount of light on the screen – whether it's an expansive, bright background or a whole frame filled with white – the S85F has to tone it down. In such scenes, brightness can drop by even four times. This limitation is well-known to essentially every OLED in this price segment, so we do not consider it a particular shortcoming. However, something that deserves praise and sets this model apart from the competition is its colour gamut coverage. Thanks to the QD-OLED panel, our colourimeter recorded values exceeding 100% DCI-P3 coverage and as much as 86% for the ultra-wide BT.2020 gamut. Such results are hard to find even in televisions costing several times more.

When it comes to brightness, the R85H performs really respectably. In most of our test scenes the TV reaches around 800 to 900 nits, and with larger bright elements it can exceed 1000 nits. These are not, of course, levels on a par with the pricier Mini-LEDs, but they are more than enough for watching films and TV shows in HDR, and the effect can already be quite noticeable. The problem reappears in more demanding scenes where there is a small bright element on a very dark background. Here the TV can significantly limit its brightness so as not to light up too large a portion of the screen. In our measurements such small highlights fell even to around 200 to 250 nits, so it is clear that a small number of zones combined with the particular behaviour of the algorithm has consequences here. Fortunately, this is not something that disturbs viewing all the time. In typical mixed HDR scenes the R85H looks good and can deliver appropriate image dynamics. It's just that with very small points of light you shouldn't expect an effect as strong as on TVs with many more zones or on OLEDs.

Samsung, as befits a manufacturer with ambitions, has equipped the S85F with a mode called Filmmaker. Its task is simple: to ensure that the colours on the newly purchased television are as true to what the director intended as possible. Sounds great… but, as is often the case, a theory that sounds great does not 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 though someone had overdone the saturation a bit. As a result, quite significant colour errors occurred, particularly in 4K content. Moreover, there was a problem with brightness – the S85F could brighten most scenes more than it should, taking away their intended mood.

Fortunately, Samsung televisions, including the S85F, offer an impressive number of settings for advanced calibrators. This means that we could test what this panel is truly capable of when placed in the right hands.

In Filmmaker mode our R85H sample performed acceptably in SDR, but a few things stood out immediately in the measurements. In the white balance red increased with rising brightness while blue decreased. As a result the brighter parts of the picture had a slightly too warm tint. Gamma only held to the target value at the start. It then gradually fell, which left most of the image a little too bright. The combination of these two effects also showed up in the colours, with errors growing particularly in the brighter and more saturated samples. It did not look bad, but for Filmmaker mode we had expected a bit more accuracy. Interestingly, in HDR our sample fared noticeably better. The white balance was much more even and, over most of the range, the individual components stayed close together. Only in the very brightest areas did red start to be lacking, causing white to shift subtly. The EOTF curve, by contrast, looked very good and followed the target luminance levels across almost the entire range. That does not mean HDR colours were perfect. The Colour Checker still showed some deviations, especially for some of the more saturated hues, but the errors were clearly smaller than in SDR.

Thanks to the vast number of settings in the menu, we managed to bring the S85F to nearly an ideal level. The white balance in SDR content? Literally perfect – deviations do not exceed the value of “1”. So we can confidently say that in materials with not very high dynamics, we have an image close to reference here.

In HDR content, slight issues have arisen, but they are not significant in practice – most errors fall below the threshold of perceptibility, which is the value of “3”. We also managed to tame the S85F when it comes to brightness management – the EOTF curve, even in movies, holds an almost perfect line. This is one of those cases where after calibration, you can comfortably forget about the settings and simply enjoy films and series at the highest level.

After calibration the R85H shows it has genuinely substantial capabilities in colour reproduction. It performed best in SDR, where the white balance could be brought almost perfectly into line and the gamma stays very close to the target value across most of the range. This also translated into very low errors on the Colour Checker, so there is really little to pick fault with. HDR also shows a clear improvement, although some things can no longer be corrected as well. At the highest brightness levels the character of the backlight begins to make itself felt and the individual components of the white balance start to drift apart. The same applies to the most saturated colours, which do not always land exactly where they should. Despite these limitations the overall image is much more accurate than with the factory settings, and the biggest difference is definitely seen in SDR. There is, however, one thing calibration cannot fix. With heavily saturated elements the colour can slightly bleed onto adjacent bright areas of the image. It is easiest to notice this on white, which can pick up a faint tint of a neighbouring colour. It does not appear in every scene, but when the material is demanding the effect can be visible. This is more a characteristic of the way the RGB backlight works than a matter of picture settings.

The tonal transition smoothing function in the S85F works really effectively – it can completely eliminate the problem of visible banding in very poor quality materials, such as those from YouTube. Unfortunately, even the lowest level of this option comes with compromises. Noise reduction is aggressive enough that it can smooth out the film grain that many of us consider a key element of the cinematic experience. At the "Standard" level, we did not notice that this function removed 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 only noise but also subtle, desirable details such as the texture of objects.

As for image scaling, the S85F performs very well. The material looks sharp, and the only minor imperfection is slightly visible aliasing of contours. And there’s still the persistent issue with Samsung televisions – overscan. This can cause the frame to be slightly cropped in certain scenes, which is worth keeping in mind when watching very old content.

In the R85H image processing is handled by the Micro RGB AI Processor. The name is new, but when it comes to upscaling lower-quality material the TV’s behaviour is very similar to what Samsung has shown before. And that’s not a bad thing, because the manufacturer has dealt with this aspect quite well for years. Lower-resolution content is displayed cleanly, edges do not become excessively soft, and the TV does not try to artificially extract details at any cost. The result is simply well balanced, and with regular broadcasts or older recordings the R85H performs as you would expect from a Samsung in this class. There remains only a minor drawback in the form of overscan, which cannot be completely turned off at the lowest resolutions. A separate matter is the additional processing of weaker sources. The R85H can smooth posterisation and somewhat tidy up heavily compressed footage, but it is worth emphasising that it does this relatively aggressively. At stronger noise reduction settings it begins to remove not only compression artefacts but also fine details and the natural film grain. It is therefore best used only when the material truly needs it.

The S85F is a mind-blowingly fast television – and this is not just an empty phrase for effect. Thanks to the 120 Hz OLED panel, dynamic scenes, whether in games or while watching a live match, look exactly as they should – smoothly, sharply, and without the feeling that something is “slipping away” from the frame. The lightning-fast pixel response time, typical of OLEDs, plays its part here. Transitions between frames are virtually instantaneous, and the picture remains clear even during the fastest camera movements. A ball flying across half the pitch? A car racing in a chase scene? Here, everything is clear and free from the characteristic “trail” of LCDs.

This is exactly what we expect from a good OLED – no compromises when it comes to motion fluidity. The S85F gives the impression that regardless of the pace of the action, we can focus on what is happening on the screen, rather than the imperfections of the image.

The R85H has a 144 Hz panel, so motion is really smooth here. Just bear in mind that the extra hertz above 120 are mainly used when connected to a PC, so in this category we don't treat them as any particular advantage. For films and TV, what's more important is that the panel is fast enough to provide access to an advanced motion-smoothing feature, "Motion Clarity", which lets you set motion anywhere from more film-like to very smooth. The panel's response time is a bit worse. Because it's a VA panel, fast-moving objects can leave a slight trail. On bright backgrounds this isn't very noticeable, but the darker the scene, the more pronounced the smearing becomes. This is a typical trait of this type of panel and it's easiest to notice in dark shots.

[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.

The S85F has practically everything on board to become the dream screen for gaming. Four full-fledged 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 – and on top of that, a gem in the form of Game Motion Plus. This motion smoother makes animation in games more enjoyable, while input lag only increases slightly. This is a rare combination, and it’s a big plus for Samsung. Now comes the moment when we need to complain a little. The lack of Dolby Vision in Samsung televisions has become standard, so there’s no point in hoping (unless something changes in a few years) – but the disappearance of HGiG after the software update is something hard to explain. HGiG (which stands for HDR Gaming Interest Group) is a mode that allows for precise reproduction of brightness in HDR games, in accordance with the creators' intentions. Without it, HDR calibration on a console becomes less precise, so we can end up with an image that is too dark in the shadows or excessively overexposed. Perhaps Samsung will fix this in the next update – and we have high hopes for that. Because if HGiG returns, the S85F will become nearly the perfect television for gamers.

Samsung has been steadily expanding its gaming features for several years, and the R85H really doesn't miss anything important here. The TV supports 4K at 120 Hz, VRR and ALLM, so we can easily take advantage of the PlayStation 5 or Xbox Series X. HGiG also works correctly, so with HDR properly set on the console, games retain the correct brightness and we don't unnecessarily lose detail in the brightest parts of the picture. The only major omission is Dolby Vision Gaming, which Samsung does not support on any of its TVs. The Game Bar is also very useful — a handy menu you can bring up without leaving the game. We can quickly check the frame rate, VRR status or change key picture settings. Samsung also adds a few less obvious features, such as the ability to change the aspect ratio and Game Motion Plus, which can further smooth games running at 30 or 60 frames per second. Of course this comes at the cost of higher input lag (around 55 ms), but for slower-paced titles it may be an interesting addition for some people.
