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

In the tested film scenes, the television Samsung OLED 48 S90D achieves impressive brightness results, surpassing 800 nits in the first four shots, which can be considered a very good result. In the case of the final shot, where a fullscreen flash of sunlight is visible, the brightness drops to around 400 nits, but still remains at an acceptable level. However, it's 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 at 97% is an excellent result, which guarantees extremely rich and realistic colour reproduction, further enhancing image 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 in choosing the size of the S90D model, it is worth mentioning that the larger versions of this television offer better HDR effects, and consequently, higher scores in our tests.

While the U8000F with a VA panel can still be praised for decent blacks, there is no longer any reason to be enthusiastic about brightness – especially in HDR scenes. The television achieves a maximum of just under 250 nits, which is simply too low to speak of any impressive light effects. Bright elements appear pale, and scenes that should sparkle look rather flat. We observed an interesting situation during the test of a scene from the film Sicario 2 – the screen became noticeably darker, 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 enhance contrast, but in practice, the effect makes very little difference, other than the fact that we see less on the screen. Furthermore, there is the issue of colours – the U8000F does not support a wide colour gamut, so one cannot count on the vibrant, saturated hues known from better models. The HDR image here resembles slightly brightened SDR and... perhaps that is even a good thing. With this model, it is not worth expecting a cinematic experience – it is better to treat HDR as a modest addition.

The S90D Samsung 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 can seem overly warm, and users switching from Standard mode may experience a slight shock. It's worth noting that this state of affairs is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue, 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. Conversely, in 4K HDR materials, the EOTF curve is situated above the recommended line, leading to some parts of the image being displayed too brightly, which can cause clipping in the brightest areas. Overall, the Samsung S90D presents a solid image right 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 it offers out of the box – the Filmmaker Mode. This profile is theoretically meant to provide a neutral, cinematic image devoid of unnecessary enhancements and artificial beautifications. In the case of SDR content – primarily in HD or SD resolution – the television performed surprisingly decently right out of the box. The only noticeable flaw 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. Considering the television's segment, it performs quite well.

However, the situation is much weaker in HDR mode. While the white balance was still acceptable, the colour inaccuracies were very apparent. In the Color Checker test, almost every sample was outside the target point, and the image itself appeared unnatural – the colours were shifted, sometimes too cool, other times simply dull and lifeless. The main problem lies in the hardware limitations – the U8000F does not support the wide colour gamut of DCI-P3, so it is physically incapable of reproducing the colours that the HDR standard anticipates. Unfortunately, this is evident in almost every more demanding scene.

After calibration, the television Samsung OLED 48 S90D in film mode looks even better than one could have presumed. The white balance, for both HD and 4K HDR content, has been improved to nearly perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the quality of the image. The colours are more balanced, which translates to a natural representation of details, particularly in scenes requiring a precise colour palette. It is worth adding that this model in the 48' size is equipped with a WOLED panel that has a different characteristic compared to larger sizes and has a smaller coverage of a wide colour gamut, not offering such rich colours as, for example, the 65-inch version, which is fitted with a QD-OLED panel.

The contrast has also undergone significant improvement. The gamma graph after calibration is much closer to the expected line, providing a better balance between the bright and dark parts of the image. The EOTF curve, which before calibration showed issues with overexposed scenes, now displays better results. This effect allows for greater detail preservation in the bright parts of the image, especially in HDR material.

Right out of the box, the U8000F offered quite a decent image in SDR for its price class. However, we managed to enhance it slightly – we reduced a subtle purple tint and improved the gamma characteristics, giving it a more natural curve. Despite these adjustments, the television still tends to overly brighten the brightest details – the gamma chart shows a clear inflection that cannot be completely corrected.

In HDR mode, however, it is noticeably weaker. It is hard to speak of any significant improvement here – despite attempts to adjust the settings, the image still presents considerable colour inaccuracies. A Delta E exceeding 7 signifies noticeable deviations that could not be effectively reduced. Unfortunately, this is a limitation of the construction itself – the U8000F simply was not designed for serious HDR. In everyday viewing in SDR, it performs quite well, but when it comes to HDR content... it's best not to have overly high expectations.

The Samsung OLED 48 S90D television performs very well in smoothing tonal transitions. Thanks to the applied technology, the transitions between colours are more fluid and natural. There is also the option to use the noise reduction function, which further smooths tonal transitions, which can be useful in certain situations. However, it is worth remembering that enabling noise reduction can also lead to the smoothing of desired film grain, which in turn can reduce the cinematic atmosphere of the image. For this reason, caution is advised when using this function, as it is better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint and excels at scaling images from lower resolutions. The S90D OLED 48 Samsung television effectively processes lower resolutions, as seen in the visible image. The outline of the model is clear and correct, looking natural and detailed as a result. Moreover, the branches of trees are well replicated, showing no strong jaggedness that could detract from the quality of the image. Thanks to effective scaling, even lower resolution materials look attractive on the screen, satisfying users who prefer a variety of content sources such as regular aerial/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 has been equipped with a feature to improve the fluidity of tone transitions, which has been implemented much better than last year. Indeed, the television still utilizes quite strong algorithms that can distort details or remove film grain, but nonetheless – it can confidently be said that it works effectively. However, not everything has gone perfectly. The U8000F has noticeable issues with slightly cutting the image when watching very old content in very low resolution. If someone plans to play their old VHS tape, they must reckon with the fact that the image may appear slightly "cut off".

The S90D television is equipped with a 120 Hz panel, with the possibility of "overclocking" to 144 Hz with the appropriate PC configuration, ensuring exceptional motion fluidity. For years, Samsung has offered a variety of image sharpness settings on a ten-point scale, allowing users to customise the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there is no sign of any blurring. The pixel response is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The image is incredibly sharp and detailed, even during fast action, making the S90D OLED 48 Samsung television an ideal choice for gamers and sports enthusiasts.

The Samsung U8000F is equipped with a 60 Hz panel, so it's clear right from the start that one shouldn't expect miracles. This is simply the standard in this class – adequate for everyday viewing, but without any fireworks. The television offers a single motion smoothing slider – a feature called "Motion Blur Reduction," which allows us to adjust the smoothness of the image in films. Higher settings produce a more "theatrical" and smoothed effect, while lower settings help retain the film's original character with a slight 24p effect. An interesting feature is "Clear Motion LED," which is the BFI mode – inserting black frames between image frames to improve motion clarity. In practice, however, the screen flickers heavily when this feature is activated and should rather be considered an experiment than something that genuinely enhances gaming comfort.

The Samsung OLED 48 S90D television is excellently tailored 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 screen responsiveness, significantly enhancing comfort during long gaming sessions. Additionally, the Game Bar feature allows for easy adjustments of settings such as screen ratios, which can be particularly useful in various 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 fluidity. Although the lack of Dolby Vision support may be a downside, it is worth noting that this technology is not as widely used in games as it is in films. Nevertheless, the S90D still offers excellent features for gamers, making it an outstanding choice for those seeking high-quality visuals and advanced gaming technologies.

Samsung U8000F offers a basic set of features for gamers, which may still be sufficient for less demanding users. It includes an automatic game mode – when a game is launched on the console, the television automatically switches to low latency mode, significantly improving response times. There is also 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 the "tearing" effect – as long as we stay within this range.

Unfortunately, that’s about it for the advantages. Additions like Game Bar or higher refresh rates are reserved for higher-end Samsung models from the 2025 line. In theory, the television also supports the HGiG feature, which should adjust HDR imagery to the creators' intentions. Unfortunately – despite the fact that this feature appears in brochures and promotional materials – its configuration on the Xbox console turned out to be... impossible in practice.
