Samsung U8000F (VA) vs Samsung S90H (WOLED)

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.

Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price bracket, although compared with the QD-OLED version it is slightly dimmer. The difference is not as significant as in last year’s F series, where the gap could reach as much as 500 nits. Here the parameters of both panels are very similar, and differences in peak brightness are only in the order of 100–150 nits. In small-area measurements the S90H on the WOLED panel easily reaches levels close to 1500 nits. Such a reserve of power allows HDR dynamics to be reproduced phenomenally; all highlights, light reflections and explosions have the necessary punch, exactly as the creators intended in the editing studio. As with most OLED displays, when a very bright scene fills the whole screen protection systems activate and brightness naturally falls to around 700 nits. It is worth emphasising that this is still an excellent result on the market. Often noticeably better than many Mini LED screens in the same segment.

Colour gamut coverage

The biggest difference between the two S90H variants lies in colour reproduction and saturation. This results directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a consequence, colours at very high brightness do not reach the same intense saturation, and the volume of the wide gamut is somewhat more limited than in QD-OLED. That does not change the fact that in everyday use these differences will be hard for most viewers to spot. The DCI-P3 space we measured reaches nearly 99% on the WOLED panel, which means that in the vast majority of real film scenes both variants will present an almost identical picture. The true distance only reveals itself in rarer, exceptionally demanding productions that use the ultra-wide BT.2020 gamut. Due to the specifics of the WOLED panel’s construction, coverage of that standard is about 15% lower compared with the S90HAT with a QD-OLED panel, so the brightest, heavily lit colours in HDR may appear slightly less vivid.

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.

In Filmmaker mode, which we strongly recommend switching on straight out of the box, the S90H offers very good factory colour tuning. Colours are natural and faithful to the creators' intent, without the irritating oversaturation found in more aggressive presets. However, as is often the case without full calibration, no two units are identical. In our test the white balance was slightly lacking in blue, causing the image to lean a little towards warmer, yellowish tones. This was most noticeable in bright scenes, such as the snowy sequences from Star Wars. Additionally, the gamma curve was slightly low at 2.2, which produced a minor lift in shadow detail. In HDR mode the tuning was somewhat better, showing only a slight undersaturation in the red region.

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.

After a full calibration it’s fair to say the S90H in WOLED guise looks almost perfect. In SDR mode colour inaccuracies drop to ultra-low levels and Delta E values very rarely exceed 2. That’s a phenomenal result, so if you care about perfectly faithful colour reproduction it’s definitely worth considering calibration. The calibrated HDR mode also performs very well, with the white balance stabilised and earlier deviations eliminated. After professional fine-tuning it’s really hard to find anything to criticise, because the TV delivers an image with almost reference-level naturalness and three-dimensionality. The slightly lower score in this category compared with the QD-OLED variant is solely due to the aforementioned limitation in saturation in extremely bright scenes; the tuning options and colour fidelity themselves are at the highest level.

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".

In terms of posterisation reduction itself, Samsung has kept the solutions known from last year’s models. The dedicated gradient-smoothing function performs quite well and can effectively mask unwanted tonal banding, which is useful on a WOLED panel that is slightly more prone to banding. However, you should be aware of its aggressive behaviour. This mechanism, alongside the artefacts themselves, can clean up fine film grain and gently soften detail. Ultimately it is a matter of compromise, but if you want an absolutely faithful reproduction, it is safer to leave this option off.

Similarly, in the area of scaling it is difficult to call this a breakthrough. The S90H uses the same NQ4 Gen3 processor as its predecessor, so the upscaling quality was almost identical. The chip sharpens lower-resolution material very well, extracting a satisfying level of detail. Samsung still has not dealt with the longstanding overscan issue, though. With some older recordings or archive footage the edges of the image can be slightly cropped. It’s a minor flaw, but it’s a pity the manufacturer still hasn’t eliminated it.

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.

In terms of motion handling, the S90H is simply excellent. This year's panel offers a boosted refresh rate of up to 165 Hz, though in practice the benefit will mainly be for gamers connecting a high-end PC. For films, series or sports broadcasts such a high refresh rate makes no difference and the picture looks exactly the same as at the standard 120 Hz. Regardless of the source, however, the OLED panel's lightning-fast response time does its job, so motion is clean and the ghosting or smearing familiar from LCD screens simply does not occur here.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.

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.

Players should feel at home with the S90H, because Samsung has left few reasons to complain in that respect. The TV has four HDMI 2.1 ports, each of which supports VRR, ALLM and high refresh rates. There’s also the Game Bar, a handy menu that lets you quickly check key parameters and change settings without leaving the game. Importantly, Samsung has also improved HGiG mode. In last year’s models it could cause problems when used with a console, but on the S90H it now works as it should. What really stands out against the competition is the Game Motion Plus feature. It’s a special motion smoothing mode for games that works best with titles running at 30 or 60 fps. Motion becomes noticeably smoother, while latency remains at a reasonable level. In our measurements it was under 50 ms, so gaming is still comfortable. That’s important, because on many TVs enabling a similar smoothing feature causes such a large increase in input lag that controls become noticeably sluggish. Samsung has managed to find a good compromise here. There’s still no Dolby Vision Gaming, but in practice Game Motion Plus may prove to be a much more useful feature.
