Samsung OLED S90F (QD-OLED) vs Samsung R95H Micro RGB

The biggest difference between the 65-inch S90F and the other versions is brightness. The QD-OLED panel can achieve up to 1700 nits in laboratory tests, which is over 500 nits more than the variant with the WOLED panel. This translates to a significantly stronger and more engaging HDR effect. In most scenes, bright parts of the image look fantastic, and we have to admit we were pleasantly surprised because we expected results closer to the WOLED version, but we got an effect that makes a big impression even in movies. As with any OLED, there are moments when the panel has to limit brightness somewhat. This mainly concerns full-screen, very demanding scenes – for example, in the last test frame from the movie "The Meg," brightness drops to around 800 nits. However, it's hard to consider this a flaw since it’s still an excellent result, unprecedented in OLED TVs in this price range. All signs indicate that the 65-inch S90F could be one of the best choices this year for those looking for a strong OLED at a reasonable price. Another advantage of the QD-OLED panel in HDR content is its color gamut coverage. Thanks to quantum dots, the television achieves almost full 100% of the DCI-P3 color gamut and nearly 90% of the BT.2020 gamut. These values place it alongside much more expensive models and make it exceptional in its class.

In terms of brightness the Samsung R95H shows that we’re still dealing with a top-tier TV, although the results aren’t always as spectacular as you might expect from a flagship Micro RGB model. In synthetic tests the TV can exceed 2,400 nits, so it definitely has plenty of headroom. Importantly, it can sustain high brightness even when bright elements occupy a larger portion of the screen. In real movie scenes the situation is a bit more complex. The R95H most often reaches around 1,000 to 1,400 nits, which still delivers a very good, strong HDR effect. Bright sunlight, reflections, or lights can look truly impressive, and the TV has enough power for HDR to be clearly distinguishable from regular SDR.

The problem appears mainly in very dark scenes with single, small light sources. Here the local dimming algorithm favors deep blacks and reducing the halo over maximizing the brightness of such elements. As a result, small lights can be noticeably dimmed. Overall HDR performs well, but not without limitations. The R95H has huge brightness headroom, especially in larger and brighter parts of the image, but in difficult, dark scenes its capabilities are mainly limited by how the local dimming operates.

Colors

Colors were meant to be the biggest revolution enabled by the RGB backlight, and the R95H does show considerable potential here. The assessment is not, however, as simple as synthetic measurements might suggest. On test charts the TV performs superbly. BT.2020 coverage reaches almost 94%, and DCI-P3 98%, so especially strongly saturated reds and greens can look really impressive. The picture changes a bit when, instead of test charts, we start measuring real movie scenes. Then BT.2020 coverage drops to about 87% and DCI-P3 to 93%. It seems that with more complex imagery the RGB zones are not always able to maintain the same high color saturation as on simple charts. They are still saturated, but the advantage of the new backlight is no longer as large as the manufacturer's numbers might suggest.

Samsung S90F, like most modern televisions, offers several picture modes, but in keeping with our tradition, we checked it in the most important one, which is Filmmaker. This setting makes the picture look much more natural than in the default, often oversaturated modes. It is neither overly saturated nor artificially subdued – just closer to what you should actually see. However, that doesn't mean it's perfect. The S90F had noticeable shortcomings in white balance, primarily in the blue range, which created a slightly yellowish filter effect on most scenes. One might argue that it looks more "cinematic" because it's warmer, but let's not kid ourselves – George Lucas didn't shoot Star Wars in sepia 😉 (you'll find a comparison with a scene below as always). In HDR materials, there was also a problem with brightness management. The EOTF curve clearly showed that the television brightens the picture more than it should, which led to some effects looking too intense and deviating from the reference. Fortunately, many of these shortcomings can be eliminated through professional calibration – we will discuss the effects of this procedure further in the test.

To assess factory color reproduction, we of course chose Filmmaker mode, the setting that's supposed to be closest to how the creators intended the image to look. Unfortunately, the R95H does not fully exploit the potential of its panel. The biggest issue in SDR is the gamma. The image is noticeably brightened across almost the entire range, which robs it of some depth and makes it look flatter than it should. The white balance isn't ideal either, as increasing brightness brings a red bias and a lack of blue, making the image too warm. This is especially visible in bright elements and skin tones, which can appear redder than they should.

It's similar in HDR. The EOTF curve sits above the reference value for much of the range, so the R95H again brightens the image compared with how it should look. Combined with the inaccurate white balance, this means colors here are not as precise as we'd expect from a TV of this class. The factory Filmmaker setup is therefore not one of the R95H's strengths. At first glance the picture may look impressive because it's bright and highly saturated, but in terms of fidelity to the source material there is still plenty of room for improvement.

Calibration quickly showed that the S90F has a substantial reserve of capabilities. The image in SDR immediately gained a natural quality – classic films stopped looking as if someone had applied a yellowish filter to them, and the colors regained their true character. It’s a return to the atmosphere of the original, without the impression that someone tried to "age" it artificially. In HDR content, the difference was even more pronounced. The EOTF curve was managed almost to a reference level, and any deviations are so subtle that most viewers won't even notice them. In practice, the S90F after calibration displays an image very close to perfection. Compared to the WOLED version, it performs even better – mainly due to the wider color gamut coverage, which makes the colors look fuller and more vibrant.

R95H responds very well to calibration. In SDR we were able to set the white balance and gamma almost perfectly, and color errors dropped to very low levels. The difference compared with the factory settings is therefore considerable, and after calibration the picture looks much more natural. In HDR we can also improve a lot, especially regarding white balance and overall color accuracy. The issue of managing brightness and color saturation looks a bit different. Here, at some point we run into limitations resulting from the way RGB backlighting and local dimming work. Individual zones have to control both brightness and the color of the light at the same time, so in more demanding scenes it is not always possible to achieve exactly the same saturation and brightness that the TV shows on simple test patterns. Calibration simply can't completely overcome that. Despite this, after calibration the R95H delivers accurate image reproduction, and most of the errors we saw in the factory settings can be effectively eliminated.

The S90F performs really well here, although there are some comments that are repeated in the case of most Samsung TVs. The noise reduction feature can effectively smooth out unwanted color transitions in lower-quality materials, such as television or YouTube, making them simply look better. However, it should be noted that it operates quite aggressively and can also soften elements that we wouldn't want to touch, like facial details. Therefore, if we want to use it, it’s best to use it in the "medium" setting and be aware of the compromise it brings. The upscaling itself is at a high level – low-quality materials are enhanced towards a 4K-like image. The only caveat is that the S90F can still have problems with so-called overscan, which is slight trimming of the edges in very poor materials like 576p and lower.

Samsung R95H uses the new Micro RGB AI Processor, but in practice we didn't notice a big leap compared to the NQ4 AI Gen2 or Gen3 chips found in the manufacturer's other TVs. The upscaling itself still performs very well. The image is appropriately smoothed, yet retains plenty of sharpness and doesn't look overly soft. That's definitely one of Samsung's strengths. It's just a shame that with very low-resolution content you still can't completely turn off overscan.

The processor also handles gradients well and can effectively smooth unwanted posterization. The noise reduction feature works very effectively, but you need to use it judiciously. At higher settings it can noticeably interfere with the image and even remove natural film grain. So it's best to use it only when the source material is actually heavily compressed.

S90F is an OLED with a refresh rate of 144 Hz, but in practice, what matters most is how it performs at 120 Hz, as this frequency is the most significant when watching sports. The QD-OLED panel is no different in this regard from WOLED panels—the pixel response is almost instantaneous, allowing motion to be rendered with surgical precision. The effect is easy to predict. The image is practically free of ghosting, making gaming on consoles, matches, or other sports broadcasts a great pleasure on the S90F.

Fans of movies and series are not forgotten either. Like every Samsung TV with a refresh rate of 120 Hz and above, the S90F is equipped with a proprietary motion smoother called "Image Clarity." Here, we find two sliders—motion blur reduction and judder reduction—that allow you to improve the fluidity of materials recorded at 24 frames and adjust the effect to your personal preferences.

The Samsung R95H has a 165 Hz panel, so its motion handling is excellent. At 120 Hz, like when gaming on a console or watching sports, motion blur is minimal, and when connected to a PC you can use the full 165 Hz to further improve motion clarity. However, keep in mind that it’s still a VA panel, so it doesn’t respond as instantly as OLED. You may sometimes notice a faint trail behind moving objects, but from a normal viewing distance this shouldn’t be distracting. For movies and series you can also use the adjustable motion smoothing. You can keep the more cinematic 24 fps look or gradually smooth the motion if you prefer a smoother image. Samsung gives you plenty of freedom here, and it’s easy to choose a setting that matches your preferences.

S90F is a television that truly brings a lot of joy when gaming. Right off the bat, we get four full-fledged HDMI 2.1 ports, which means you can connect all consoles and PCs without having to figure out which device takes priority. This is a convenient and practical solution that is not a given with other manufacturers. Additionally, there are key features such as the automatic game mode (ALLM), which switches the screen to low-latency settings, and VRR frame synchronization working over a wide range from 48 to 144 Hz. This ensures that the picture remains smooth regardless of whether we are playing fast-paced online shooters or calmer story-driven titles. Another noteworthy feature is the Game Bar – a panel that allows quick access to several useful additions. For example, you can turn on an additional crosshair in the center of the screen, enlarge the minimap, or, in the case of a PC, change the aspect ratio. Finally, there is also the unique Game Motion Plus mode exclusive to Samsung. Its purpose is to smooth out older or less optimized titles, and it actually works quite well. Thanks to this mode, even less polished games can look better and provide more enjoyment than on other televisions that theoretically offer the same technical specifications.

When it comes to gaming the Samsung R95H is almost a complete TV. When you connect a PS5 or Xbox Series X you can use 4K at 120 Hz, VRR and ALLM, and the TV also works properly with HGiG. The only major omission is Dolby Vision Gaming, which Samsung, like with its other TVs, simply does not support. There's also the Game Bar, familiar from other Samsung models, which lets you quickly check frame rate, VRR status or the HDR format and change the most important settings without leaving the game. You can also brighten darker parts of the image or change the screen aspect ratio.

Samsung also offers Game Motion Plus, a motion smoothing feature designed specifically for games. It makes the most sense for games running at 30 fps, where it can noticeably improve smoothness and make camera movement look much nicer. Just remember this comes at the cost of higher input lag (about 60 ms), so it's not the best choice for online or faster paced games. It's also worth noting Gaming Hub, which lets you run some games directly from the cloud without connecting a console. In terms of features for gamers, it's hard to find any major omissions in the R95H.
