Samsung S90D / S94D 48" (WRGB OLED) vs Samsung U8000F (VA)

In the tested movie scenes, the Samsung S90D delivers impressive brightness levels, exceeding 800 nits in the first four shots—a very strong result. In the final shot, featuring a full-screen burst of sunlight, brightness drops to approximately 400 nits, which is still acceptable. Notably, larger versions of this model exceed 1,000 nits, offering even more impressive performance. Additionally, the colour space coverage of DCI-P3 at 97% ensures rich and realistic colour reproduction, greatly enhancing image quality. For those considering the size of the S90D, it is worth noting that larger variants with QD-OLED panels deliver even better HDR performance, making them an excellent choice for those seeking optimal visual fidelity.

While the U8000F with a VA panel can still be praised for decent blacks, there are no longer any reasons to be impressed regarding brightness – especially in HDR scenes. The television reaches a maximum of just under 250 nits, which is simply too little to talk about any impressive light effects. Bright elements come off as pale, and scenes that should shine look rather flat. An interesting situation was observed during the test of a scene from the movie Sicario 2 – the screen noticeably darkened, as if the television were trying to hide its limitations in displaying blacks. One might get the impression that the device artificially darkens the image to improve contrast, but in practice, the effect doesn't make much of a difference, other than that we see less on the screen. Additionally, there's the issue of colors – the U8000F does not support a wide color gamut, so don't expect vibrant, saturated shades known from better models. The HDR image here resembles slightly brightened SDR and… maybe that’s even a good thing. For this model, it's not worth setting expectations for cinematic experiences – it's better to treat HDR as a modest addition.

The Samsung S90D television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more demanding users. This mode may seem too warm, and users who switched from Standard mode may experience a slight shock. It is worth noting that this state of affairs is caused by poor settings, for example, in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue colour, causing colours to become warmer than they should be. In practice, this means that some shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma graph indicates slight fluctuations, causing the image to be minimally darker, especially in shadows. This may affect less distinct details in darker scenes. Meanwhile, in 4K HDR materials, the EOTF curve is above the recommended line, which leads to some parts of the image being displayed too brightly, potentially causing clipping in the brightest areas. Overall, the Samsung S90D presents a solid picture straight out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

The Samsung U8000F has been tested by us in the best picture mode available out of the box – namely, Filmmaker Mode. This profile is supposed to provide a neutral, cinematic image, free of unnecessary enhancements and artificial beautifications. In the case of SDR content – mainly in HD or SD resolution – the television performed surprisingly well right out of the box. The only noticeable imperfection was brightness management. The gamma chart showed some deviations – slight brightening or dimming of certain tones – but in practice, it did not significantly affect the viewing experience. For a television in this segment, it performs quite well.

However, the situation is considerably weaker in HDR mode. Although white balance was still acceptable, color errors were very pronounced. In the Color Checker test, almost every sample was outside the target point, and the image itself looked unnatural – colors were shifted, sometimes too cool, at other times simply dull and lifeless. The main problem lies in the hardware limitations – the U8000F does not support the wide color gamut of DCI-P3, so it is physically unable to reproduce the colors anticipated by the HDR standard. And unfortunately, this is evident in almost every more demanding scene.

After calibration, the S90D TV delivers an even more impressive performance in movie mode. The white balance for both HD and 4K HDR content is now nearly perfect. While there are still some minor imperfections, they are so subtle that they don't significantly impact the overall image quality. The colours are more balanced, offering a natural depiction of details, especially in scenes that require precise colour accuracy.

It's important to note that the 48-inch model features a WOLED panel, which differs from the larger sizes. This results in a smaller coverage of the wide colour gamut, meaning it doesn't offer the same rich colours as the 65-inch version, which is equipped with a QD-OLED panel.

Contrast has also seen a substantial improvement. The gamma curve after calibration is much closer to the ideal line, achieving a better balance between bright and dark areas of the image. The EOTF curve, which previously showed issues with overly bright scenes, now performs much better, retaining more detail in the bright sections of the image, especially in HDR content.

Right out of the box, the U8000F offered quite a decent picture in SDR for its price range. However, we managed to slightly enhance it – we reduced a subtle purple tint and improved the gamma characteristics, giving it a more natural curve. Despite these adjustments, the TV still tends to brighten the brightest details a bit too aggressively – the gamma graph shows a clear dip that cannot be fully corrected.

On the other hand, in HDR mode, it is noticeably weaker. It's hard to talk about any significant improvement here – despite attempts to tweak the settings, the picture still presents considerable color errors. A Delta E exceeding 7 means noticeable deviations that couldn't be effectively reduced. Unfortunately, this is a limitation of the design itself – the U8000F was simply not designed for serious HDR. In everyday SDR viewing, it performs quite well, but when it comes to HDR content... it's best not to have too high expectations.

The S90D TV excels in smoothing tonal transitions, offering natural and seamless colour shifts. Thanks to its advanced technology, it ensures a smoother visual experience overall. The noise reduction feature can further enhance tonal transitions, making it beneficial in certain situations. However, it’s important to note that enabling noise reduction may also smooth out the film grain, which can detract from the cinematic feel. For this reason, it's advisable to use the feature sparingly, preserving the natural grain that adds depth and authenticity to the content.

Samsung continues to impress with its scaling capabilities, with the S90D effectively processing lower-resolution content. The image is sharp and clear, maintaining proper outlines and presenting details accurately. For example, tree branches are rendered well, with no noticeable jagged edges that would compromise image quality. Thanks to the effective scaling, even lower-resolution materials are displayed attractively, making it a great choice for users who enjoy content from diverse sources, such as regular antenna or cable television.

When it comes to how the Samsung U8000F handles lower quality materials, we must admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same position in the lineup. This year's model is equipped with a feature for improving the fluidity of tonal transitions, which has been implemented much better than last year. Yes, the TV still uses quite strong algorithms that can distort details or remove film grain, but despite that – it can be confidently said that it works effectively. However, not everything went perfectly. The U8000F has noticeable issues with slight image stuttering when watching very old content in very low resolution. If someone plans to play their old VHS tape, they should be prepared for the image to appear slightly "choppy."

The S90D TV features a 120 Hz panel, which can be "overclocked" to 144 Hz with the appropriate PC setup, delivering exceptional motion fluidity. Samsung has long offered a range of image clarity settings on a ten-point scale, allowing users to fine-tune the display to their liking. In the UFO test, the OLED panel ensures no ghosting, with pixel response being instantaneous and perfectly capturing dynamic movements. OLED technology, in this regard, is considered one of the best on the market. The image remains incredibly sharp and detailed, even during fast-paced action, making the S90D TV a top choice for gamers and sports fans alike.

The Samsung U8000F is equipped with a 60 Hz panel, so right from the start, it's clear that we shouldn't expect miracles. This is simply standard in this class – sufficient for everyday viewing but without any frills. The TV offers one motion enhancement slider – a feature called "Motion Blur Reduction," which allows us to adjust the smoothness of the image in movies. Higher settings give a more "theatrical" and smoothed effect, while lower settings help maintain the original character of the film with a slight 24p effect. An interesting feature is "Clear Motion LED," which is a BFI mode – inserting black frames between image frames to improve motion sharpness. However, in practice, the screen flickers heavily when it's activated, and it should be treated more as an experiment than something that genuinely improves gaming comfort.

The S90D TV is perfectly designed with gamers in mind, offering four HDMI 2.1 ports that support features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HGIG (HDR Gaming Interest Group). These technologies ensure smoother gameplay and faster screen response, enhancing comfort during extended gaming sessions. The Game Bar feature also provides convenient access to settings like aspect ratio, which can be particularly useful for different game types. For PC users, the television offers an impressive refresh rate of 144Hz, with Nvidia and AMD graphics cards supporting G-Sync and FreeSync, further boosting image smoothness. While the lack of Dolby Vision support may be a limitation, it’s worth noting that this technology is less commonly used in gaming compared to movies. Nevertheless, the S90D still provides excellent features for gamers, making it a top choice for those seeking high-quality visuals and advanced gaming technologies.

Samsung U8000F offers a basic set of features for gamers, which nonetheless may be sufficient for less demanding users. It has an automatic game mode – when a game is launched on the console, the TV automatically switches to low latency mode, significantly improving response time. It also includes a VRR feature, or variable refresh rate, which operates in the range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce a "tearing" effect on the screen – as long as we stay within this range.

And unfortunately, that's about it when it comes to advantages. Additions like Game Bar or higher refresh rates are reserved for higher models of Samsung from the 2025 line. In theory, the TV also supports the HGiG function, which should adjust the HDR image to the intentions of game developers. Unfortunately – even though this feature appears in brochures and marketing materials – its configuration on the Xbox console turned out to be... impossible in practice.
