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

In the tested movie scenes, the Samsung OLED 48 S90D television achieves impressive brightness results, exceeding 800 nits in the first four shots, which can be considered a very good outcome. In the case of the last shot, where a full-screen burst of sunlight is visible, the brightness drops to around 400 nits but still remains at an acceptable level. However, it is worth noting that this model in larger sizes offers higher values, exceeding the "barrier" of 1000 nits. Additionally, speaking of the DCI-P3 colour space coverage value of 97% is an excellent result, which guarantees extremely rich and realistic colour reproduction, further enhancing the picture quality. However, once again it should be remembered that the panel in the 65' variant equipped with a QD-OLED panel will be even better in this aspect. For those hesitating about the size of the S90D model, it is worth noting that larger versions of this television offer a better HDR effect, and consequently, a higher score in our tests.

While the U8000F with its VA panel can still be praised for decent blacks, there are no such accolades when it comes to brightness—particularly in HDR scenes. The television only achieves a maximum of just under 250 nits, which is simply too low to talk about any impressive light effects. Bright elements appear washed out, and scenes that should shine look rather flat. An interesting situation occurred during our testing of a scene from the movie Sicario 2— the screen noticeably darkened, as if the television was 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 difference, apart from the fact that we see less on the screen. Additionally, there’s the issue of colours—the U8000F doesn’t support a wide colour gamut, so one shouldn’t expect vibrant, saturated hues known from better models. The HDR image here resembles a slightly brightened SDR and... maybe that’s not such a bad thing. For this model, it’s not worth expecting a cinematic experience—better to treat HDR as a modest addition.

The S90D Samsung TV 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 a bit too warm, and users who switched from Standard mode may experience a slight shock. It's worth considering that this state of affairs is caused by poor settings, such as white balance, rather than the Filmmaker mode itself. Both in SDR and HDR content, the device exhibits drops in blue, causing colours to appear warmer than they should. In practice, this means that some shades, like sky blue or skin tones, may seem less natural and take on a pinkish or yellowish tint. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma chart indicates minor fluctuations, resulting in a slightly darker image, especially in the shadows. This may affect the clarity of details in darker scenes. Conversely, in 4K HDR materials, the EOTF curve is above the recommended line, leading to some portions of the image being too bright, which can cause clipping in the brightest areas. Overall, the Samsung S90D presents a solid image straight out of the box, but for the best results, particularly with more demanding content, additional calibration is recommended.

Samsung U8000F has been tested by us in the best picture mode it offers out of the box – that is, Filmmaker Mode. This profile is supposed to theoretically 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 already presented itself surprisingly reasonably 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, this did not significantly affect the viewing experience. For a television in this segment, it performs quite well.

However, the situation in HDR mode looks significantly weaker. Although white balance was still acceptable, colour errors were very evident. In the Color Checker test, almost every sample was outside the target point, and the image itself appeared unnatural – colours were skewed, sometimes too cool, and at other times simply dull and lifeless. The main issue lies in hardware limitations – the U8000F does not support the wide colour gamut of DCI-P3, so it is physically unable to reproduce the colours that the HDR standard intends. Unfortunately, this is evident in almost every more demanding scene.

After calibration, the Samsung OLED 48 S90D in movie mode looks even better than one might have assumed. The white balance, for both HD and 4K HDR content, has been improved to near perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the picture quality. Colours are more balanced, which translates into a natural reproduction of details, especially in scenes requiring a precise colour palette. It’s worth noting that this model in the 48' size is equipped with a WOLED panel that has different characteristics compared to larger sizes and has a smaller coverage of a wide colour gamut, not offering as rich colours as, for example, the 65-inch version, which is equipped with a QD-OLED panel.

Contrast has also seen significant improvement. The gamma chart after calibration is much closer to the expected line, providing better balance between the bright and dark portions of the image. The EOTF curve, which showed issues with overexposed scenes before calibration, now shows better results. This effect allows for greater detail retention in bright parts of the image, particularly in HDR material.

Right out of the box, the U8000F offered a pretty decent picture in SDR for its price range. We managed to tweak it a bit further – we reduced a slight purple tint and improved the gamma characteristics, giving it a more natural curve. Despite these adjustments, the TV still has a tendency to overly brighten the brightest details – the gamma chart shows a clear break that cannot be fully corrected.

On the other hand, in HDR mode, it’s noticeably weaker. It's hard to talk about any significant improvement – despite attempts to fine-tune the settings, the picture still presents considerable colour errors. A Delta E exceeding 7 indicates noticeable deviations that we couldn’t effectively reduce. Unfortunately, this is a limitation of the construction itself – the U8000F simply wasn't designed for serious HDR. In daily SDR viewing, it performs quite well, but for HDR content... it’s best not to have overly high expectations.

The Samsung OLED 48 S90D television performs exceptionally well in smoothing tonal transitions. Thanks to the technology used, the transitions between colours are more fluid and natural. It is also possible to utilise the noise reduction feature, which further smooths tonal transitions, which can be useful in some situations. However, it's worth remembering that turning on noise reduction can also lead to the smoothing of desired film grain, which may reduce the cinematic feel of the picture. For this reason, caution is advised when using this feature, as it's better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint, and in terms of scaling images from lower resolutions, it performs excellently. The S90D OLED 48 Samsung television effectively processes lower resolutions, as seen in the visible photo. The outline of the model is clear and correct, making it look natural and detailed. Furthermore, the branches of the trees are well reproduced, showing no significant jaggedness that could detract from the image quality. Thanks to effective scaling, even lower resolution materials look attractive on the screen, satisfying users who prefer diverse content sources such as regular antenna/cable television.

When it comes to how the Samsung U8000F handles lower-quality materials, we have to admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same place in the lineup. This year’s model is equipped with a feature that improves the smoothness of tonal transitions, which has been implemented much better than last year. Yes, the television still uses quite strong algorithms that can distort details or remove film grain, but still – it can be confidently said that it works effectively. However, not everything has gone 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 must be prepared for the image to look slightly “choppy”.

The S90D television is equipped with a 120 Hz panel, with the ability to "overclock" to 144 Hz with the right PC configuration, providing exceptional motion smoothness. Samsung has been offering a variety of image clarity settings on a ten-point scale for years, allowing users to customise the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there's no question of any ghosting. The response time of the pixels is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The picture is extremely sharp and detailed, even during fast action, making the S90D OLED 48 Samsung television the perfect choice for gamers and sports enthusiasts.

The Samsung U8000F comes with a 60 Hz panel, so right from the start, it's clear that you can't expect miracles. It's simply the standard in this class – sufficient for everyday viewing, but without any fireworks. The TV offers one motion smoothing slider – a function called "Motion Blur Reduction", which allows us to adjust the smoothness of the image in films. Higher settings provide a more "theatrical" and smoothed effect, while lower settings maintain the original character of the film with a slight 24p effect. Interestingly, there is the "LED Clear Motion" feature, or BFI mode – which inserts black frames between the frames of the image to improve motion sharpness. However, in practice, the screen flickers significantly when this is activated, and it's best to treat this as more of an experiment rather than something that genuinely improves the gaming experience.

The Samsung OLED 48 S90D television is well-suited to the needs of gamers, 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). With these technologies, gamers can enjoy smoother gameplay and faster on-screen response, significantly enhancing comfort during long gaming sessions. Additionally, the Game Bar feature allows for easy adjustment of settings, such as aspect ratios, which can be particularly useful in different types of games. For PC users, the television offers an impressive refresh rate of 144Hz, and Nvidia and AMD graphics cards support G-Sync and FreeSync, further improving image smoothness. Although the lack of Dolby Vision support may be a drawback, it's worth noting that in gaming, this technology is not as widely used as in films. Nevertheless, the S90D still offers excellent features for gamers, making it a great choice for those seeking high-quality visuals and advanced gaming technologies.

Samsung U8000F offers a basic set of features for gamers, which can still prove sufficient for less demanding users. Here we have an automatic gaming mode – when a game is launched on the console, the TV switches to low-latency mode by itself, significantly improving response time. We also find the 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 the 'tearing' effect on the screen – as long as we stay within this range.

Unfortunately, that's about it when it comes to advantages. Add-ons 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 feature, which should adjust the HDR image to the intentions of game developers. Unfortunately – despite this feature appearing in advertising brochures and store materials – its setup on the Xbox console turned out, in practice, to be... impossible.
