Hisense U8Q vs Samsung S85F (WOLED)

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.

For the majority of the time, let's say in 90% of film scenes, viewers will see virtually no difference between the versions of the S85F. When small, but very bright light points appear on the screen – a lantern in a dark alley, an explosion, the sun breaking through the clouds – this WOLED panel (similar to the smaller S85F) performs exceptionally well. Our measurements indicated a peak brightness of around 750 nits. We can state with full confidence: this is a great result that guarantees fantastic HDR effects. The problem arises in a very specific, uncomfortable situation for any OLED. We're talking about the moment when the entire screen must light up at full power brightly. Examples include a scene with a white background, a skiing scene, or our test sequences (5) from the film The Meg. And here, unfortunately, the results diverge significantly to the detriment of the variant with the WOLED panel. Our measurement equipment was able to register a maximum brightness of around 250 to 300 nits in such conditions. To be clear: the same model with a QD-OLED panel in the same test is nearly twice as bright. The second matter: colours. And here, we also have to be honest – QD-OLED has a structural advantage. Why? It's simple. QD-OLED generates colours from three components (red, green, and blue) and does not require an additional white subpixel. The WOLED panel we are testing here uses that white subpixel mainly to boost overall brightness. The effect is that QD-OLED is able to show a slightly wider colour palette and the colours are somewhat "purer". But to be clear: it's not that the colours on this WOLED panel are bad! On the contrary, they are really very good. The coverage of the DCI-P3 film palette at 97% and 71% for the broader BT.2020 palette is still high-end. We just need to honestly admit that this few percentage points of advantage in colour coverage lies with QD-OLED technology and may be noticeable in very specific moments.

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.

When it comes to factory colour reproduction, our test sample in SDR mode suffered from a slight deficit of red and yellow colours. This resulted in a faint yellowish tint visible in shades of white. However, this is not the biggest problem with the S85F. As with the variant with a QD-OLED panel, the main issue with this model is the way it presents HDR content. When we look at the EOTF curve chart, it is easy to see that the television has quite significant problems with strong image clipping. Such behaviour causes the final image in many scenes to become very unnatural.

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.

After conducting calibration in Filmmaker mode, we managed to eliminate most of the unwanted effects. In SDR content, the television performs excellently, with its colour reproduction errors not exceeding a value of 2, which is an outstanding result. HDR content looks slightly worse, though still very good. Although we were able to eliminate the significant unnaturalness of the image caused by the excessively high EOTF curve, the most discerning observers may notice that it is not perfectly aligned. It runs slightly below the reference curve, which would suggest that the S85F has minor difficulties in showcasing all the details in the image. We must emphasise here that it is very unlikely that the average viewer will notice any shortcomings in the image. The final effect after calibration is evaluated as exemplary.

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 processing of tonal transitions (gradients) in the S85F is at a high level. The television effectively handles posterisation (the "banding" effect of colours), even with heavily compressed content, e.g., from streaming services. However, using this feature requires a certain compromise. We noticed that the noise reduction algorithm is quite aggressive – even at the lowest setting, it can eliminate natural film grain, which for many viewers is part of the film's aesthetics. The "Standard" setting seems to be a happy medium, not causing a noticeable loss of important details, which is why we can recommend it. However, we advise against using the "High" level, which, in addition to noise, also removes desirable details such as texture or structure of objects on the screen.

The upscaling process of lower resolution content works very well in the S85F. The image is sharpened and clear. The only minor imperfection we managed to observe is occasional, subtle aliasing on the edges. The television still exhibits characteristics typical of this manufacturer, namely active "overscan" (slight image enlargement). It is worth keeping this in mind, especially when watching older content, as it may result in minimal clipping of the original frame.

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.

S85F is a model with impressive speed. The use of a 120 Hz OLED panel ensures that dynamic scenes, both in games and during sports broadcasts, meet expectations: smoothly, sharply, and without loss of clarity. A key role here is played by the instant response time of the pixels, which is a natural advantage of OLED technology. Frame transitions are instantaneous, and the image remains clear even during the fastest camera movements. Moving objects, such as a ball on the pitch or a car in a chase scene, are clear and devoid of the characteristic motion blur associated with LCD panels (the so-called "ghosting").

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 😉

The 85F has practically everything on board to become the dream screen for gaming. It features four full-fledged HDMI 2.1 ports with a bandwidth of 48 Gb/s, support for VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). Additionally, there's a super-detailed Game Bar, which clearly displays all the key parameters. However, the real gem is the Game Motion Plus feature. This motion smoother dedicated to games makes animations more pleasant to the eye while only slightly increasing input lag. This is a rare and well-working combination, for which Samsung deserves great applause.

Now for the moment where we have to complain a bit. The lack of Dolby Vision in Samsung TVs is already a standard, so there's no point in holding out hope (unless something changes in the future). Unfortunately, it's much harder to explain the disappearance of support for HGiG after one of the software updates. HGiG (HDR Gaming Interest Group) is a key mode that allows for precise brightness representation in HDR games, according to the creators' intent. Without it, HDR calibration on consoles becomes less precise, potentially leaving us with images that are too dark in the shadows or excessively blown out in the bright areas. Perhaps Samsung will fix this in the next update – we have high hopes for that. Because if HGiG returns, the S85F will become nearly the perfect TV for gamers.

[UPDATE] We have updated our tests of Samsung TVs from the 2025 model year due to the release of software version 1131, which has restored the HGiG feature essential for gamers.
