Samsung OLED S85F / S84F (QD-OLED) vs Samsung R85H / R86H

As an OLED, the Samsung S85F can really shine – literally. Under favorable conditions, it can generate brightness exceeding 750 nits. This is hugely significant because most movies are created with displays 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 massive amount of light on the screen – whether it's a vast bright background or an entire screen filled with white – the S85F must tone it down. The brightness can drop by even four times in such scenes. This limitation is known to basically every OLED in this price range, so we don't consider it a particular failing. However, something that deserves praise is what sets this model apart from the competition – color gamut coverage. Thanks to the QD-OLED panel, our colorimeter showed values exceeding 100% DCI-P3 coverage and as high as 86% for the ultra-wide BT.2020 palette. Such results are hard to find even in televisions that cost several times more.

If it’s about brightness, the R85H performs really well. In most of our test scenes the TV reaches around 800 to 900 nits, and with larger bright elements it can break 1000 nits. These aren't, of course, levels on par with the most expensive Mini-LEDs, but they're more than enough for watching movies and TV series in HDR, and the effect can be quite noticeable. The problem shows up again in more demanding scenes where there's a small bright element on a very dark background. Here the TV can significantly reduce its brightness so it doesn't illuminate too much of the screen. In our measurements such small highlights dropped to around 200 to 250 nits, so you can see that a limited number of local dimming zones combined with the specific behavior of the algorithm has its consequences. Fortunately, it's not something that bothers you all the time. In typical mixed HDR scenes the R85H looks good and can deliver appropriate image dynamics. You just can't expect the same punch from very small points of light as you get with TVs that have many more zones or with OLEDs.

Samsung, as befits a manufacturer with ambitions, equipped the S85F with a mode called Filmmaker. Its task is simple: to make the colors on the newly purchased television as true to what the director wanted us to see as possible. Sounds great… but, as often happens, a great-sounding theory 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 overdone the saturation a bit. As a result, quite significant color errors appeared, particularly in 4K content. To make matters worse, there was a brightness issue – 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 we could check what this panel is truly capable of when it gets into the right hands.

In Filmmaker mode our R85H sample performed adequately in SDR, but a few things immediately showed up in the measurements. In the white balance, as brightness increased more red crept in while blue decreased. As a result, the brighter parts of the image had a slightly too warm tint. On top of that, gamma only held to the target value at the start. It then gradually fell, making most of the image a bit too bright. The combination of the two also affected colors — errors grew especially in the brighter, more saturated samples. It didn’t look bad, but for Filmmaker mode we expected a bit more accuracy. Interestingly, in HDR our unit handled things noticeably better. White balance was much more even and, for most of the range, the individual RGB components stayed close together. Only in the brightest areas did red begin to fall short, causing the white point to shift slightly. The EOTF curve looked very good, tracking the target luminance values across almost the entire range. That doesn’t mean HDR colors were perfect. The ColorChecker still shows some deviations, particularly in some of the more saturated hues, but the errors are clearly smaller than in SDR.

Thanks to the vast 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". Thus, it can be confidently said that in materials with not very high dynamics, we have an image close to reference.

In HDR content, minor issues did arise, but they are of little significance in practice – most errors fall below the threshold of perception, which is a value of "3". We also managed to tame the S85F regarding brightness management – the EOTF curve, even in films, adheres to an almost perfect line. This is one of those cases where after calibration, you can comfortably forget about the settings and simply enjoy movies and series at the highest level.

After calibration the R85H shows it has impressive color reproduction capabilities. It performed best in SDR, where the white balance was brought almost perfectly into line and the gamma stays very close to the target across most of the range. That also translated into very low errors in the ColorChecker, so there's really little to fault here. HDR also shows a clear improvement, although some issues can't be corrected as well. At peak brightness the character of the backlight itself starts to show and the individual components of the white balance begin to diverge. The same goes for the most saturated colors, which don't always land exactly where they should. Despite these limitations, overall the image is significantly more accurate than on the factory settings, and the biggest difference is clearly in SDR. However, there's one thing calibration can't fix. With highly saturated elements, color can subtly bleed onto adjacent bright parts of the image. It's easiest to notice this on white, which can pick up a slight tint from a neighboring hue. It doesn't occur in every scene, but when the content is demanding the effect can be visible. This is more a characteristic of the way the RGB backlight works than an issue with picture settings.

The tone transition smoothing feature in the S85F works really well – it can completely eliminate the problem of visible bands in very poor quality materials, even from YouTube. Unfortunately, even the lowest level of this option comes with compromises. Noise reduction is aggressive enough that it can smooth out film grain, which many of us consider an element of the cinematic atmosphere. At the "Standard" level, we did not notice that this feature 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 not only noise but also fine, desirable details such as the texture of objects.

When it comes to image scaling, the S85F performs very well. The material looks sharp, and the only minor imperfection is slightly visible contour jaggedness. And there’s the ongoing issue with Samsung televisions – overscan. This can cause some scenes to have their frames slightly trimmed, 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 in terms of upscaling lower-quality content, the TV’s behavior remains very similar to what Samsung has shown before. And that’s not a bad thing, since the company has handled this aspect quite well for years. Low-resolution material is displayed cleanly, edges don’t become overly soft, and the TV doesn’t try to artificially extract details at any cost. The result is simply balanced, and with regular TV or older recordings the R85H performs as you would expect from a Samsung at this level. The only minor drawback is overscan, which can’t be completely turned off at the lowest resolutions. A separate issue is the additional processing of weaker sources. The R85H can smooth posterization and tidy up heavily compressed footage a bit, but it’s worth stressing that it does so relatively aggressively. At stronger "noise reduction" settings it starts removing not only compression artifacts but also fine details and natural film grain. It’s best to use it only when the material actually needs it.

S85F is a hellishly fast television – and this is not just an empty catchphrase 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 "escaping" from the frame. The lightning-fast pixel response time, typical of OLEDs, plays a crucial role here. Transitions between frames are practically instantaneous, and the image remains clear even during the fastest camera movements. A ball flying across half the field? A car racing in a chase scene? Everything here is clear and free of the characteristic "trail" found in LCDs.

This is exactly what we expect from a good OLED – zero compromises in motion fluidity. The S85F gives the feeling that regardless of the pace of the action, we can focus on what is happening on the screen, rather than on the imperfections of the image.

R85H has a 144 Hz panel, so motion is really smooth here. Just remember that the extra hertz above 120 will mainly be used when connected to a PC, so in this category we don't treat them as a particular advantage. For movies 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 us set motion from more film-like to very smooth. The panel's response time is a bit weaker. Because this is a VA panel, fast-moving objects can leave a slight trail. On bright backgrounds that's not very noticeable, but the darker the scene, the more visible the smearing becomes. That's a typical characteristic of this type of panel, and it's easiest to spot in dark scenes.

[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 it needs to become the dream screen for gaming. Four fully-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 is a motion interpolator that makes animation in games more enjoyable, with only a slight increase in input lag. This is a rare combination, and Samsung deserves a big plus for it. Now comes the moment where we have to complain a bit. The lack of Dolby Vision in Samsung TVs is already 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 that’s hard to explain. HGiG (which stands for HDR Gaming Interest Group) is a mode that allows for precise reproduction of brightness in HDR games, according to the creators' intention. Without it, HDR calibration on the console becomes less precise, so we might end up with an image that's too dark in the shadows or overly bright. Perhaps Samsung will fix this in the next update – and we have high hopes for that. Because if HGiG returns, the S85F will become almost the perfect TV for gamers.

Samsung has been steadily expanding its gamer-focused features for several years, and the R85H really lacks nothing important in that area. The TV supports 4K at 120 Hz, VRR and ALLM, so you can easily take advantage of the capabilities of the PlayStation 5 or Xbox Series X. HGiG also works correctly, so with the right HDR settings on the console games retain proper brightness and you don't unnecessarily lose detail in the brightest parts of the image. The only major omission is Dolby Vision Gaming, which Samsung doesn't support on any of its TVs.

Game Bar is also very useful, a handy menu you can bring up without leaving the game. You can quickly check the frame rate, VRR operation, or change the most important picture-related settings. Samsung also adds a few less obvious features, such as the ability to change the aspect ratio or Game Motion Plus, which can further smooth games running at 30 or 60 fps. Of course, this comes at the cost of higher input lag (around 55 ms), but for slower-paced titles it may be an interesting option for some players.
