SAMSUNG OLED S95F (QD-OLED) vs Samsung OLED S90F (QD-OLED)

The new generation of QD-OLED panels in the Samsung S95F shows its full potential, and the brightness results are absolutely stunning. In test film scenes, such as "Life of Pi" or "Sicario 2," where smaller light elements appear – stars, the moon, or headlights – the TV was able to achieve over 2000 nits of brightness. This is a result that surpasses even most top Mini-LED models.

The secret lies in the technology itself – instead of a limited number of dimming zones like in Mini-LED TVs, we have millions of glowing pixels here, allowing the TV to fully showcase its power without technological compromises. Of course, since it is still an organic panel, in full-screen scenes flooded with white – like in the final sequence of the film The Meg – the brightness drops to around 1400 nits. Nevertheless, the result remains excellent and definitely exceeds what any OLEDs, both QD-OLED and WOLED, have offered so far. The color reproduction also deserves special attention. Thanks to QD-OLED technology, the TV achieves almost 100% coverage of the DCI-P3 color palette and about 80% in BT.2020. These values make the HDR image not only dazzling with brightness but also captivating with a richness of colors.

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.

The best picture mode right out of the box is undoubtedly Filmmaker Mode – a mode that Samsung has been using for several years, designed to faithfully represent the creators' intentions. In SDR content, its implementation is not bad, although some imperfections can be noticed. The picture is slightly dimmed, and the screen has a slight pinkish tint resulting from the predominance of red and blue in the white balance. Color errors remained at a level of 3–4 ΔE units – and for the uninitiated: a value above 3 is the threshold where the average human eye begins to notice differences.

However, much larger problems arise in HDR content. Here, the white balance was not such a significant issue – a slight excess of blue did not cause major problems. The issue became managing brightness. In practice, the TV "overexposed" the image too much, causing details in the blacks to completely disappear. The final effect was far from what was expected, and the color errors in this mode became really large. It's hard to say why such a design decision was made, but it was clear that the factory HDR settings did not allow this TV to showcase its full potential.

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.

After calibrating, it was possible to make subtle adjustments in white balance and significantly improve the image characteristics. In SDR content, the quality has become practically reference-level—most color errors have fallen below a ΔE value of 1, which is the level at which the human eye can no longer detect differences. This is a result that places the S95F among the absolute top televisions available on the market.

In HDR materials, calibration also brought significant improvement. The tendency of the television to overexpose the image was successfully controlled, as confirmed by the analysis of the EOTF curve. A slight tendency to brighten the entire scene or occasional loss of details in the blacks can still be observed; however, it does not significantly impact the overall perception. After calibration, the S95F showcases its full potential and can be described as one of the best televisions on the market!

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.

The Samsung S95F offers a noise reduction feature that smooths tonal transitions. It works very effectively, but in practice, it can be too aggressive. Materials of lower quality – such as older recordings or videos from YouTube – become soft and plastic when this feature is turned on, resembling an image digitally smoothed in a graphics program. Unfortunately, this also causes the natural film grain, which often adds authenticity to the image, to disappear. Fortunately, the TV does not lose too many fine details, such as in skin textures or elements of the surroundings. Therefore, this feature is best used with caution – depending on preferences, one can achieve a smooth image, but less natural, or one that is more faithful to the original. In our opinion, the most universal choice is the “Standard” setting.

The image scaling performs significantly better. The TV handles lower resolution materials well – even 576p content looks quite decent, although a slight blockiness can be noticed. Overall, the effect is very good, although it is somewhat inferior to what Sony Bravia 8 (II) or LG G5 can achieve. It's also worth mentioning a small imperfection of the S95F – in older materials, overscan may occur, causing a slight cropping of the left edge of the image.

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.

The Samsung S95F demonstrates phenomenal motion fluidity. The panel itself operates at a native 4K resolution with a refresh rate of up to 165 Hz, and combined with QD-OLED organic technology, it delivers incredible results. Sports and games look amazing – the image is fast, dynamic, and very natural. Additionally, the built-in motion smoother and motion blur reduction system allow you to adjust the character of the image to your preferences. You can opt for a more "frame" effect with visible film structure or a smooth, theatrical performance. Every viewer will find a setting that suits them.

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 same advantages of low motion blur and excellent motion fluidity characteristic of OLED panels are just the beginning, as the Samsung S95F was designed with gamers in mind. The manufacturer has equipped it with four HDMI 2.1 ports – although limited to a bandwidth of 40 Gb/s, in practice, this has no impact on compatibility with consoles or PCs. We get a complete set of gaming features: variable refresh rate (VRR), automatic game mode (ALLM), as well as a very well-implemented HGiG standard, which allows HDR titles to appear as their creators intended. The whole thing is complemented by the Game Bar – a clear settings hub where we can preview and change all key picture parameters with one movement. The proprietary motion smoother Game Motion Plus also deserves praise, as it can smooth out animation, which is particularly useful in productions running at 60 frames, where stability is not always exemplary. Although support for Dolby Vision in games is lacking, it is hard to consider this a serious drawback – Samsung compensates for it with other solutions. This is one of the best, if not the best, gaming TVs available today on the market.

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.
