Samsung 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 reach up to 1700 nits in laboratory tests, which is over 500 nits more than the variant with a WOLED matrix. This translates to a decidedly stronger and more engaging HDR effect. In most scenes, bright parts of the image look fantastic, and we must admit that we were positively surprised, as we expected results more similar to the WOLED version, but we got an effect that makes a great impression even in films. Just like with every OLED, there are moments when the panel needs to limit its brightness a bit. This mainly refers to full-screen, very demanding scenes – for example, in the last test frame from the film "The Meg," the brightness drops to around 800 nits. However, it is hard to consider this a disadvantage, as it is still an excellent result, unprecedented in OLED televisions in this price range. Everything suggests 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 matrix in HDR content is its colour gamut coverage. Thanks to quantum dots, the television achieves almost a full 100% of the DCI-P3 colour space and nearly 90% of the BT.2020 colour space. 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 it is still a high-end TV, although the results are not always as spectacular as one might expect from a flagship Micro RGB model. In synthetic tests the TV can exceed 2400 nits, so it clearly has plenty of headroom. Crucially, it can maintain high brightness even when bright elements occupy a larger portion of the screen. In real cinematic scenes the situation is a little more complex. The R95H most often reaches around 1000–1400 nits, which still delivers a very good, powerful HDR effect. Bright sun, reflections or lights can look genuinely impressive, and the TV has enough power for HDR to be clearly distinguishable from standard SDR.

The problem appears mainly in very dark scenes with single, small light sources. Here the local dimming algorithm prioritises deep black and reducing halo over maximising the brightness of such elements. As a result, small highlights can be noticeably dimmed. Overall HDR therefore 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 primarily limited by the way local dimming operates.

Colours

Colours were supposed to be the biggest revolution brought by RGB backlighting, and indeed the R95H shows considerable potential here. The assessment is not, however, as simple as synthetic measurements alone might suggest. On test patterns the TV performs superbly – BT.2020 coverage reaches almost 94%, and DCI-P3 98%, so particularly strongly saturated reds and greens can look truly impressive. The situation shifts somewhat when, instead of test patterns, we start measuring real film scenes. Then BT.2020 coverage falls to about 87%, and DCI-P3 to 93%. It seems that with more complex images the RGB zones are not always able to maintain the same high colour saturation as on simple charts. They remain saturated, but the advantage of the new backlight is no longer as large as the manufacturer’s figures might suggest.

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

For assessing factory colour reproduction we naturally chose the Filmmaker mode, the setting that is supposed to be closest to how the picture was intended by the creators. Here, unfortunately, the R95H does not fully exploit the potential of its panel. The biggest problem in SDR concerns the gamma. The image is noticeably brightened across almost the entire range, which makes it lose some depth and look flatter than it should. The white balance itself is also not ideal; as brightness increases there is 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 look more "reddish" than they should.

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

Calibration quickly revealed that the S90F has a significant margin of capability. The image in SDR immediately gained a natural quality – classic films no longer looked as if someone had applied a yellowish filter to them, and the colours regained their proper character. It is a return to the atmosphere of the original, without the impression that someone tried to "age" it forcefully. 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 shows an image very close to perfection after calibration. Compared to the WOLED version, it performs even better – mainly due to the wider colour gamut coverage, which makes the colours appear fuller and more intense.

The R95H responds very well to calibration. In SDR we managed to set the white balance and gamma almost perfectly, and colour errors fell to a very low level. The difference compared with the factory settings is therefore substantial and after calibration the picture looks noticeably more natural. In HDR we can also make considerable improvements, particularly in terms of white balance and overall colour accuracy. The issue of managing brightness and colour saturation is somewhat different, though. At a certain point we run up against limitations inherent in the RGB backlight and local dimming. Individual zones must control both the brightness and the colour of the light simultaneously, 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 cannot completely overcome that. Despite this, after calibration the R95H delivers accurate image reproduction, and most of the errors we saw on the factory settings can be effectively eliminated.

The S90F performs really well here, although there are some comments that recur with most Samsung televisions. The noise reduction feature can effectively smooth out unwanted colour transitions in poorer 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 we wouldn't want to touch, like facial details. Therefore, if we want to use it, it’s best to set it to 'medium' and be aware of the compromise it entails. The upscaling itself is at a high level – low-quality materials are upscaled towards a 4K-like image. The only caveat is that the S90F can still struggle with so-called overscan, meaning it slightly trims edges with very poor materials like 576p and lower.

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

The processor also handles colour gradation well and can effectively smooth unwanted posterization. The noise reduction function is really effective, but you need to use it with care. At higher settings it can start to interfere quite heavily with the image and even remove natural film grain. For that reason it's best used only when the source material is actually heavily compressed.

S90F is an OLED with a refresh rate of 144 Hz, but in practice, it primarily indicates how it performs at 120 Hz, as this frequency is most significant when watching sports. The QD-OLED panel is no different in this regard from WOLED panels – the response of the pixels is nearly instantaneous, so motion is rendered with surgical precision. The result is predictable. The image is virtually devoid of motion blur, making gaming on consoles, matches, or other sports broadcasts incredibly enjoyable on the S90F.

Fans of films and series have not been overlooked either. Like every Samsung television with a refresh rate of 120 Hz and above, the S90F features a proprietary motion smoothing technology called "Image Clarity." Here, we find two sliders – blur reduction and judder reduction – which allow for improved fluidity of materials recorded at 24 frames and tailoring the effect to personal preferences.

Samsung R95H has a 165 Hz panel, so its motion handling is really good. At 120 Hz, for example when gaming on a console or watching sport, motion blur is minimal, and when connected to a PC you can use the full 165 Hz and further improve motion clarity. However, bear in mind it is still a VA panel, so it does not respond as instantly as OLED. You may sometimes notice a faint trail behind a moving object, but from a normal viewing distance this is unlikely to be bothersome. For films and TV shows 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 picture. Samsung gives plenty of flexibility here, so you can easily choose a setting to suit your own preferences.

The S90F is a television that truly brings a lot of joy when gaming. To start, we have four full-fledged HDMI 2.1 ports, which means you can connect all consoles and PCs without worrying about which device has priority. This is a convenient and practical solution that is by no means a given with other manufacturers. Additionally, there are key features such as automatic game mode (ALLM), which automatically switches the screen to low-latency settings, and VRR frame synchronization that operates in a wide range from 48 to 144 Hz. As a result, the picture remains smooth regardless of whether we're playing fast-paced online shooters or more leisurely narrative titles. The Game Bar also deserves a mention – a panel that allows quick access to several useful additions. For example, you can enable an additional crosshair in the centre of the screen, enlarge the minimap, or, in the case of PC, change the aspect ratio. Lastly, there is also the unique Game Motion Plus mode from Samsung. Its purpose is to smooth out older or poorly optimized titles, and it actually works pretty well. Thanks to this mode, even less polished games can look better and provide a more enjoyable gaming experience than on other televisions that theoretically offer the same technical specifications.

In terms of 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 correctly with HGiG. The only larger omission is Dolby Vision Gaming, which Samsung simply does not support, as with its other televisions. There is also the Game Bar, already seen on other Samsung models, which lets you quickly check the frame rate, VRR status or HDR format and change the most important settings without leaving the game. You can also brighten darker parts of the picture or change the screen aspect ratio.

Samsung also offers Game Motion Plus, a motion-smoothing function developed specifically for games. It makes most sense in titles running at 30 fps, where it can noticeably improve smoothness and make camera movement feel much more pleasant. You should remember, though, that this comes at the cost of higher input lag (about 60 ms), so it is probably not the best choice for online or more fast-paced games. It's also worth mentioning the Gaming Hub, which lets you run some games directly from the cloud without connecting a console. In terms of gamer-focused features, it is therefore hard to find any major shortcomings in the R95H.
