Samsung S85F OLED vs Hisense U8Q

For an OLED, the Samsung S85F can truly shine – literally. Under favourable conditions, it is capable of generating brightness exceeding 750 nits. This is hugely significant, as most films are created with displays reaching around 1000 nits in mind. In practice, this means that in scenes with moderately large, bright elements, the image can look simply fantastic. However, it's not always so rosy. When there is a huge amount of light on the screen – whether it's an expansive, bright background or a whole frame filled with white – the S85F has to tone it down. In such scenes, brightness can drop by even four times. This limitation is well-known to essentially every OLED in this price segment, so we do not consider it a particular shortcoming. However, something that deserves praise and sets this model apart from the competition is its colour gamut coverage. Thanks to the QD-OLED panel, our colourimeter recorded values exceeding 100% DCI-P3 coverage and as much as 86% for the ultra-wide BT.2020 gamut. Such results are hard to find even in televisions costing several times more.

When it comes to HDR, the Hisense U8Q shows its claws. On paper, that is, in synthetic measurement tests, the television can achieve nearly 4000 nits of peak brightness. This is a value that most models can only envy. In practice, this translates to very strong light effects in films – in some scenes, we managed to measure a real brightness of between 1500 and 2000 nits, which is a level typically reserved for the absolute top tier of televisions on the market.

Of course, it's not always perfect. In small, pinpoint elements, brightness can drop – a good example is scene number 4 from the film Sicario 2, where instead of thousands of nits, we get around 500. But it’s worth noting that the effect does not disappear completely – the light is still visible, and the image does not seem artificially dimmed. This is a typical issue with Mini LEDs, so it's difficult to consider this a major downside.

On the other hand, the colour reproduction is a huge plus. Thanks to additional coatings that enhance colour saturation, the U8Q nearly covers the entire DCI-P3 colour space (98%), and for the wider BT.2020 range, it achieved over 80%. This is an excellent result that makes HDR films look rich, vivid, and simply very cinematic.

Samsung, as befits a manufacturer with ambitions, has equipped the S85F with a mode called Filmmaker. Its task is simple: to ensure that the colours on the newly purchased television are as true to what the director intended as possible. Sounds great… but, as is often the case, a theory that sounds great does not always translate into perfect practice.

In the tested unit, it quickly became apparent that the image – due to an excess of blue and red – looked as though someone had overdone the saturation a bit. As a result, quite significant colour errors occurred, particularly in 4K content. Moreover, there was a problem with brightness – the S85F could brighten most scenes more than it should, taking away their intended mood.

Fortunately, Samsung televisions, including the S85F, offer an impressive number of settings for advanced calibrators. This means that we could test what this panel is truly capable of when placed in the right hands.

We must admit that when the U8Q arrived at our editorial office, we were slightly surprised… and positively so. Usually, in televisions, the white balance immediately requires adjustment – it can be too warm or too cold, which immediately leads to strange colour mistakes. Meanwhile, here the situation looks really good straight out of the box. Of course, we are talking about our unit, so there is no guarantee that every model will be equally well calibrated, but in our case, the first impressions were very positive. The only more apparent issue concerned the way the television manages brightness. Looking at the EOTF graph, it is clear that the U8Q tends to brighten small elements on the screen. This, in turn, caused what we mentioned earlier – slight overexposure and the impression that the entire scene can be a bit too bright. However, this is not a flaw that undermines the picture, rather an effect characteristic of this model.

Thanks to the vast number of settings in the menu, we managed to bring the S85F to nearly an ideal level. The white balance in SDR content? Literally perfect – deviations do not exceed the value of “1”. So we can confidently say that in materials with not very high dynamics, we have an image close to reference here.

In HDR content, slight issues have arisen, but they are not significant in practice – most errors fall below the threshold of perceptibility, which is the value of “3”. We also managed to tame the S85F when it comes to brightness management – the EOTF curve, even in movies, holds an almost perfect line. This is one of those cases where after calibration, you can comfortably forget about the settings and simply enjoy films and series at the highest level.

Of course, we wouldn’t be ourselves if we didn’t make adjustments to the white balance. After calibration, we managed to equalise the SDR signal to practically perfection – older films, YouTube content, and classic television looked almost ideal on the U8Q. This is truly an exceptional level that shows this model can do a lot if given a bit of help. Unfortunately, the situation is different with HDR content. The colours themselves don’t pose many problems, but the U8Q’s biggest issue remains the EOTF brightness characteristics. In practice, the television tends to “over-expose” beyond how the image should look in its original form. It’s that slight "bleeding" that we noticed earlier in comparisons with the best screens on the market. It’s a bit of a shame that this characteristic can’t be fully tamed – if we could maintain equally good control over brightness in HDR as in SDR, we would be dealing with an absolutely reference-quality image.

The tonal transition smoothing function in the S85F works really effectively – it can completely eliminate the problem of visible banding in very poor quality materials, such as those from YouTube. Unfortunately, even the lowest level of this option comes with compromises. Noise reduction is aggressive enough that it can smooth out the film grain that many of us consider a key element of the cinematic experience. At the "Standard" level, we did not notice that this function removed anything significant from the image, so we can recommend this setting. On the other hand, the "High" level is a different story – it can smooth out not only noise but also subtle, desirable details such as the texture of objects.

As for image scaling, the S85F performs very well. The material looks sharp, and the only minor imperfection is slightly visible aliasing of contours. And there’s still the persistent issue with Samsung televisions – overscan. This can cause the frame to be slightly cropped in certain scenes, which is worth keeping in mind when watching very old content.

Hisense U8Q handles lower quality materials quite well. The television can smooth out tonal transitions thanks to the "Smooth and Gradient Picture" feature – it works best when set to Medium. At this setting, it nicely dims unwanted bands and unevenness in the picture, but importantly, it does not remove the film grain or fine details.

The upscaling itself is also at a good level. Images from lower resolutions appear smooth and soft, sometimes even overly so – we get a plastic effect that may not appeal to everyone. Fortunately, this can be easily corrected with the sharpness slider, allowing the picture to be adjusted to personal preferences.

The S85F is a mind-blowingly fast television – and this is not just an empty phrase for effect. Thanks to the 120 Hz OLED panel, dynamic scenes, whether in games or while watching a live match, look exactly as they should – smoothly, sharply, and without the feeling that something is “slipping away” from the frame. The lightning-fast pixel response time, typical of OLEDs, plays its part here. Transitions between frames are virtually instantaneous, and the picture remains clear even during the fastest camera movements. A ball flying across half the pitch? A car racing in a chase scene? Here, everything is clear and free from the characteristic “trail” of LCDs.

This is exactly what we expect from a good OLED – no compromises when it comes to motion fluidity. The S85F gives the impression that regardless of the pace of the action, we can focus on what is happening on the screen, rather than the imperfections of the image.

Hisense U8Q features a panel that can refresh the image up to 165 Hz in 4K resolution. In practice, this will primarily be utilised by PC gamers, but as the saying goes – it’s better to have it than not 😊. For films and series, we have a built-in smoothness enhancer called Ultra Motion Smoothness. In the settings, it can be easily adjusted to suit personal preferences – whether we want a more “cinematic” frame rate or a smooth, theatrical spectacle.

[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.

The S85F has practically everything on board to become the dream screen for gaming. Four full-fledged HDMI 2.1 ports with a bandwidth of 48 Gb/s, support for VRR, ALLM, a super-detailed Game Bar that clearly shows all parameters – and on top of that, a gem in the form of Game Motion Plus. This motion smoother makes animation in games more enjoyable, while input lag only increases slightly. This is a rare combination, and it’s a big plus for Samsung. Now comes the moment when we need to complain a little. The lack of Dolby Vision in Samsung televisions has become standard, so there’s no point in hoping (unless something changes in a few years) – but the disappearance of HGiG after the software update is something hard to explain. HGiG (which stands for HDR Gaming Interest Group) is a mode that allows for precise reproduction of brightness in HDR games, in accordance with the creators' intentions. Without it, HDR calibration on a console becomes less precise, so we can end up with an image that is too dark in the shadows or excessively overexposed. Perhaps Samsung will fix this in the next update – and we have high hopes for that. Because if HGiG returns, the S85F will become nearly the perfect television for gamers.

In terms of features, the Hisense U8Q has practically everything one could expect from a modern gaming television. Thanks to the new processor, the manufacturer managed to implement as many as three HDMI 2.1 ports, so there is no problem connecting several consoles or a computer. On top of that, it includes all the key technologies – Game Bar with parameter preview, variable refresh rate (VRR), automatic low latency mode (ALLM)… in a word, a complete set.

But as is often the case with Hisense, it fell a bit short of perfection. The biggest drawback remains the lack of support for the HGiG format, which allows the brightness of the television to be adjusted to the console and maximises HDR in games. It’s a shame, because if this element were included, we would have a device practically made for gamers. As it stands, the U8Q remains “only” a very good choice 😉
