Samsung OLED S95D vs Samsung OLED S90F (QD-OLED)

Samsung S95D offers excellent HDR performance, providing uniform effects across all scenes exceeding 1500 nits, except for the fifth scene, where brightness drops to 800 nits. Despite this, the television maintains a high level of image quality. A significant advantage of QD-OLED technology is its ability to retain high brightness even in the smallest elements on a black background, which is uncommon in LCD and mini LED televisions. This ensures that every scene captivates with strong light effects, regardless of the size of the illuminated surface. Only in the brightest scenes with large light areas does brightness slightly decrease, which is typical even for standard LG-produced OLEDs. Additionally, the quantum dot coating has allowed for unprecedented high coverage of the BT.2020 colour gamut at 88%.

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 Samsung S95D’s Filmmaker mode excels in colour accuracy, making it ideal for true-to-life viewing and closely reflecting the intent of content creators. We rely on this mode for all testing, as it presents significantly more detail than the often oversaturated standard or dynamic modes. Initially, viewers may find the image slightly warmer in Filmmaker mode, but it brings out a more authentic, balanced display. Despite being in the premium segment, the factory settings aren’t perfect. For example, there is a dip in red tones in the white balance for both HD and HDR content, with Colour Checker tests showing a cooler colour bias that shifts the image towards blue, impacting the natural appearance of scenes. In the sample photo, the boy appears in cooler tones, which diminishes realism.

Brightness performance for HD content is generally on point, though minor inconsistencies appear. However, the more noticeable issue arises with 4K HDR content. While the EOTF curve seems accurate in test patterns, real scenes sometimes reveal fluctuations, where some areas are overly brightened or darkened. Although the S95D offers reasonably good out-of-the-box colour reproduction, calibration is recommended to achieve a more precise, natural, and immersive picture, maximising the television’s 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.

Calibration can significantly elevate a television's image quality, enhancing both accuracy and overall viewing experience. For the Samsung S95D, calibration has notably refined the white balance, removing major colour inaccuracies to produce more natural and balanced tones, which allows for a closer representation of the filmmakers’ vision. The adjustments bring subtle improvements to contrast and gamma, with more pronounced distinctions between light and dark areas, adding depth and revealing finer details in both shadows and highlights. This creates a richer, more lifelike image with enhanced detail, particularly in darker scenes where shadows now hold greater clarity, while bright areas appear well-balanced rather than overly intense.

Despite these improvements, the EOTF curve remains slightly below ideal, which might influence the handling of dynamic scenes. However, the enhanced tonal transitions and boosted contrast post-calibration make the S95D an excellent choice for film and high-definition content, bringing it closer to reference-level quality. This calibration enables the television to deliver a more immersive, accurate visual experience in line with industry standards, ultimately offering a more rewarding viewing experience.

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 S95D handles tonal transitions in lower-quality materials exceptionally well. In tests featuring a screen with a light bulb, there are virtually unnoticeable transitions between shades of grey, positioning it among the best televisions we have evaluated in this aspect.

Regarding digital processing, the S95D excels in rendering the entire image—whether it's branches or figures—without any jagged edges or overly pronounced contours. However, one point to note is that the image appears slightly trimmed. Despite this minor issue, the television still performs admirably, ensuring that details in lower-quality materials remain noticeable and well-defined. This ability to maintain clarity and depth in various content types further solidifies the S95D's reputation for delivering a high-quality viewing experience.

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 S95D TV, featuring a refresh rate of 120 Hz (and even 144 Hz when configured correctly for PC use), guarantees exceptional motion smoothness. Samsung provides a range of image sharpness settings on a ten-point scale, enabling users to customise the display according to their preferences— favouring a more cinematic look or a smoother, theatrical feel.

In UFO tests, the OLED panel demonstrates its strengths by effectively eliminating any blurring. The rapid pixel response ensures that dynamic movements are replicated with remarkable precision, resulting in a fluid viewing experience that enhances fast-paced content, such as action films or competitive gaming. This combination of high refresh rates and superior pixel response makes the S95D an outstanding choice for those seeking crisp, clear motion in their visual media.

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 S95D TV is expertly designed to meet the needs of gamers, featuring four HDMI 2.1 ports that support essential functionalities like Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). While the HDMI 2.1 ports do not offer the full 48Gb bandwidth, they are still adequate for achieving the desired resolution and smooth performance.

These technologies enable players to experience smoother and more responsive gameplay, significantly enhancing comfort and performance during intense gaming sessions. A standout feature is the Xbox app, which facilitates cloud gaming without requiring a console. This allows gamers to access an extensive range of titles directly on the TV, enjoying high image quality and fluid gameplay.

Additionally, the S95D includes a Game Bar feature, making it easy to manage game settings with quick adjustments, such as changing the screen ratio—an extremely useful function for various games and gameplay modes. The support for G-Sync and FreeSync is another advantage, particularly for Nvidia and AMD graphics card users.

Although the S95D lacks support for Dolby Vision, it still provides an impressive array of features, making it an ideal choice for console gaming enthusiasts. Overall, the S95D combines cutting-edge technology with exceptional picture quality, creating a comprehensive package for any gamer seeking an immersive experience.

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.
