Samsung S85D vs Samsung QN90F / QN92F

Brightness is an important factor in televisions, and the S85D offers a level similar to older OLED models. While it’s not outstanding in this area, it comes at a very competitive price. With peak brightness at 600 nits, HDR content looks sharp, delivering a hint of cinematic quality at home. Like many budget OLEDs, though, very bright, full-screen scenes—such as the final shot in The Meg—may cause the brightness to drop by nearly half, which is noticeable compared to pricier models. However, with 99% DCI-P3 colour coverage, the S85D delivers vibrant, accurate colours.

The Samsung QN90F can truly shine in brightness. In our measurements, it achieved over 2200 nits, which directly translates to the viewing experience. Practically, this means that when a very bright scene appears in a movie – for example, the sunrise in The Meg – the screen looks as if natural light is actually shining on us. This isn’t just a number from a chart, but a real sense of image intensity! However, the TV cannot always deliver that full power. With smaller details, such as headlights or lamps, the brightness drops to 500–700 nits. This is a conscious decision by the algorithms – this way, the contrast between large and small elements is better controlled, and the image does not 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 consistent and credible. The only downside is the colors. The coverage of the DCI-P3 palette stopped at 91%, which can be considered a rather average result in this price range.

The Filmmaker mode on the Samsung S85D offers the best factory settings, but it is not free from flaws, particularly noticeable in colour reproduction. The white balance chart for HD and HDR content shows clear issues – both red and blue are significantly weakened, leading to a dominance of green. The result is an unnatural yellowish glow that can affect the perception of realistic scenes. The Colour Checker test also highlights issues, with colour samples deviating from expected values – for HD materials, colours tend to be too saturated, with a noticeable shift towards green, as seen in the white balance chart. In contrast, for 4K HDR content, colours appear too dull and lack depth, diminishing the attractiveness and naturalness of the image. This effect is particularly noticeable in delicate scenes where colour precision plays a key role, which can be disappointing for discerning viewers who expect faithful reproduction of details and colour intensity.

When it comes to brightness, the gamma chart for HD content produces positives, but there is a noticeable spike at the end, exceeding a value of 2.4. Although this is not a major problem in most scenes, in more demanding sequences it can affect the clarity of bright details. For 4K content, the problematic aspect is the EOTF curve, responsible for delivering brightness. The initial part of the chart shows a small spike. This phenomenon can result in excessive boosting of brightness in the brightest areas of the image, leading to loss of detail in very bright scenes.

Although the Samsung S85D’s factory settings are reasonable, especially in Filmmaker mode, it is worth considering a manual adjustment of settings to improve some imperfections, particularly in colour reproduction.

We tested color reproduction in the QN90F in Filmmaker mode, and as usual with Samsung TVs, this mode proves to be the best starting point right out of the box. However, this does not mean that the image is free from flaws. The white balance in SDR and HDR content was surprisingly good – the colors didn’t shift in any direction, and even in the factory setting, it looked solid. However, a problem arose with the gamma and EOTF curves, which are responsible for how the TV manages brightness. Here, the QN90F significantly brightened the entire image, causing black levels and colors to lose their intensity, and the overall effect resembled a milky filter being applied. Fortunately, Samsung, unlike many competitors in the miniLED world, provides users with a lot of tools to control the settings that we don’t find with other manufacturers, such as Chinese brands. Therefore, we decided to check if it was possible to extract the full potential of the QN90F because we know that such a high series can deliver much more.

After calibration, Filmmaker mode on the Samsung S85D truly stands out. White balance adjustments across all content types yield significantly more natural colour reproduction. In the Colour Checker test, colour reproduction errors are minimal and well within acceptable limits, reflecting precise and true-to-life hues. Factory settings fell short in this regard, but now colours appear realistic, as though accurately rendered according to the creators’ intent. This marks a substantial improvement over previous generations, where colours often appeared distorted or overly saturated.

Brightness also benefits from calibration, becoming sharper and more refined. The Gamma, already fairly consistent, is now even more stable, delivering a deeper and more natural image. Adjustments to the EOTF curve enhance detail visibility in darker areas and improve contrast balance. With these refinements, the television provides a nearly reference-quality image, greatly enriching the experience of movies and HDR content.

After our adjustment of the settings, the QN90F showed what it is really capable of – and it must be admitted that it has one of the best images we have seen on a miniLED screen this year. As we mentioned earlier, the white balance was not a major issue even in its factory version, but only after the gamma calibration were we able to get close to nearly reference values. The same is true for HDR content, where the EOTF curve after correction presents mature and consistent results. Indeed, in some films, it can be noticed that the smallest elements of the image are slightly brightened, and with a limited number of dimming zones, there is still a risk of the halo effect. It should be remembered, however, that such phenomena are characteristic of all miniLED televisions, and it's hard to expect miracles even from the QN90F. The most important thing is that after calibration, the television shows an image that, in terms of conveying the director's vision, confidently competes even with many OLED screens available on the market.

Samsung S85D performs excellently in image scaling and smoothing tonal transitions. Like other Samsung models, the TV offers three noise reduction modes: off, standard, and high. While it improves gradation well, it unfortunately also removes film grain, which many viewers desire to give the image a cinematic character. Grain often adds authenticity and a certain rawness to films, which is lost after smoothing. Removing grain can make the image look too sterile and smoothed out, which takes away some of the charm of the original film material. As for image scaling, the Samsung S85D handles lower resolution content perfectly – the model in the photo and the branches in the background are shown correctly, without significant jagged edge issues. The only noticeable drawback is the presence of overscan, which can sometimes cut off parts of the image, which may not be to everyone's taste.

QN90F handles upscaling very well. Materials in lower resolution, even SD, are boosted to a clear and sharp image, showcasing plenty of details in the background. This is a significant advantage because the television makes older content or everyday TV look much better than on most budget screens. However, the issue of overscan remains, which is the trimming of the edges of the screen that cannot be turned off in Samsungs. This can cause some subtitles on the screen to disappear or a relative's face from a wedding on a VHS tape to be slightly cropped. 😉

The digital image processing also works well. In the menu, we find a feature called "noise reduction," which can smooth out tonal transitions and improve the reception of lower-quality materials, such as from YouTube. In medium setting, the effect is the most beneficial – it does not heavily interfere with details while eliminating the "stair-stepping" problem in colors. However, it is important to remember that the feature can be quite aggressive and can also remove natural grain in older films, so it's best to use it in moderation.

As expected from an OLED television, the Samsung S85D offers excellent motion fluidity. Equipped with a 120 Hz panel and a fast response time, the television delivers very smooth playback of dynamic scenes without visible blurring. For movie enthusiasts, there is a feature called "Image Clarity Settings," which allows you to adjust motion fluidity to individual preferences on a 10-point scale. Motion blur reduction increases the sharpness of fast-moving objects, while judder reduction smooths out motion, eliminating the "stuttering" effect. This allows every user to set the appropriate level of clarity that best suits their taste, from a more cinematic effect to clearer, smoother movements.

The QN90F is equipped with a panel that has a maximum refresh rate of 165 Hz, and while primarily PC gamers will appreciate this advantage, it is 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 plays a more significant role here. With the "Motion Clarity" setting, we can adjust the image to our own preferences. The blur reduction option is responsible for smoothness and trailing in sports. Meanwhile, the "judder reduction" function improves motion smoothness in productions recorded at 24 frames, such as movies and series. If we set it high, the film looks smoother and more fluid than it was actually filmed. Lower values, on the other hand, maintain its cinematic "rawness" with the visible film frame.

The Samsung S85D is an excellent choice for gamers due to its many modern features that facilitate and enhance gameplay. The TV has four full-bandwidth HDMI 2.1 ports, allowing you to connect the latest consoles without worrying about image quality or frame rate limitations. This means support for 4K resolution at 120 Hz, which is ideal for modern titles. Additionally, the Samsung S85D has an ALLM (Auto Low Latency Mode) function that automatically switches to low latency mode when it detects a gaming device. This way, you don't have to manually switch settings—the TV takes care of ensuring a quick response time, which is crucial in games where every second counts.

The VRR (Variable Refresh Rate) feature and G-Sync support are further elements that make gameplay smoother. VRR adjusts the refresh rate to match the frame rate generated by the console or PC, eliminating screen tearing and stuttering. This is particularly useful in dynamic games where the frame rate can fluctuate. Auto Motion Plus Game is a feature that Samsung has introduced with gamers in mind, and it's worth appreciating. Thanks to it, the image in games becomes smoother—30 frames per second looks like 45, and 60 Hz gains fluidity, approximating a 90 Hz effect. Meanwhile, there is no significant increase in input lag, which remains below 25 ms, distinguishing this feature from others available on the market. Gamers can enjoy smoother visuals without worrying about a decline in responsiveness.

Samsung has also taken care of something extra—the TV has a built-in Xbox Game Pass app, which means you can play in the cloud without the need for a console. This is a great solution for those who want to enjoy gaming without investing in additional hardware. All you need is internet access, and you have a vast library of games at your fingertips. This makes the Samsung S85D a great choice for both casual gamers and more advanced ones.

QN90F has nearly everything to become the perfect television for gamers. Things like four HDMI ports, VRR, ALLM, and refresh rates reaching up to 165 Hz are probably well-known. It deserves high praise for the Game Motion Plus mode, which is a proprietary motion smoothing technology for games. Thanks to this, it 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 televisions – competitive systems usually do not offer this – which is why Samsung has had a strong bargaining chip 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 televisions from the 2025 model year due to the release of software version 1131, which restored the crucial gaming feature HGiG.

So why are we writing about a “nearly” perfect screen? Unfortunately, similar to recent Samsung models, we noticed an issue with the lack of the HGiG feature. This solution allows the television 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 it disappeared after software updates. Instead of minor tweaks, we received a step back. It’s a shame because if it weren't for this absence, the QN90F could truly be the perfect choice for gamers in the miniLED category.
