Sony Bravia 8 MK2 vs Samsung S90H (QD-OLED)

Thanks to the new QD-OLED panel, the Sony Bravia 8 II can achieve astronomically high brightness levels of around 2000 nits, translating into nearly reference-quality for films and series recorded in HDR format. In test materials such as Life of Pi and Sicario 2, the effect is truly captivating – details in bright areas of the image remain perfectly visible, and night scenes enchant with depth and contrast. However, it is not perfect. Compared to its fiercest competitors, the Bravia 8 II shows a noticeable drop in brightness during full-screen, very bright scenes. When comparing maximum peak luminance with 100% white brightness in HDR mode, the Bravia 8 II appears even two or three times dimmer than LG G5 or Samsung S95F models. This was especially evident in a scene from the film The Meg – the screen became noticeably darker than in competing televisions. Despite this shortcoming, the results of the Bravia 8 II still place it among the top of the market. It deserves praise for its absolutely top-tier colour gamut coverage – nearly 100% DCI-P3 and close to 90% BT.2020. These parameters allow for fully extracting the potential of HDR content and providing experiences akin to those in a cinema within the comfort of home.

The Samsung S90H is a genuinely bright TV for the mid-range OLED segment. In synthetic tests its peak brightness reached around 1650 nits. That’s an impressive result in this class, roughly 50% higher than what we have seen from previous models in this price bracket. Most importantly, these tests translate directly to real video material. In four out of five film clips we tested, the S90H’s brightness ranged between 1300 and 1500 nits. That headroom allows it to reproduce most HDR films with very high dynamic range and without obvious compromises, especially in material mastered to 1000–1500 nits. In practice light effects, reflections and explosions have the appropriate punch, and the picture does not appear dimmed. Of course, on full-screen very bright scenes the result is naturally lower and drops to around 900 nits. This is a direct result of the OLED panel’s protection systems working to prevent overload. Even in this scenario there is little to complain about. Those 900 nits across the whole screen is still a very high level, ensuring excellent dynamic range in HDR content.

Colour has always been a major strength of QD-OLED TVs, and the S90H is no exception. The DCI-P3 colour space we measured reached a full 100% (actually 99.9%), while coverage of the much wider BT.2020 gamut hit about 89%. That’s an excellent result, enabling very saturated and vivid colours in HDR content. It’s worth emphasising that QD-OLED’s advantage over WOLED panels is not limited to palette coverage alone. In practice it’s mainly visible in the higher brightness of saturated colours, that is in a greater colour volume. As a result, intense reds, greens and blues in HDR look more vibrant and more striking.

Straight out of the box, the Bravia 8 II performs quite well. In the best IMAX® Enhanced mode, the television is able to render colours in a pleasant and natural way, although “good” doesn’t mean “best in class” here. The white balance definitely needs adjustment – skin tones tend to lean towards slightly pink/cool hues, both in SDR and HDR materials. We also noticed that the characteristic of the EOTF curve reveals a certain tendency to brighten the darkest parts of the image. This is probably due to the manufacturer’s desire to highlight as many details as possible even in deep shadows. Is this a good approach? It’s hard to say definitively, but we know one thing – it is not an ideal solution.

The next stage of the test was to check how the S90H handles colour reproduction without any calibration. As always, we carried out the measurements in Filmmaker Mode, the best factory picture preset. And here Samsung really deserves praise. The factory tuning is at a very high level, and a few years ago this was not one of its strong points. The average colour error (Delta E) remained around 3, which is below the level at which most people can notice any inaccuracies. Only in the brightest shades of grey did the values slightly approach 4, but even then it's hard to regard this as a real problem while watching. For out-of-the-box settings, the result is simply excellent.

After calibration, the excessive cooling of the image caused by an overly strong boost of the blue colour was mainly eliminated. The reds have become deeper, and skin tones have taken on a natural, healthy appearance. The actors, who previously seemed "cold," now look much livelier and more convincing on screen. However, one thing has not changed – the analysis of the EOTF curve still shows that the Bravia 8 II has a tendency to brighten the darkest areas of the image. It is difficult to determine whether this is a deliberate method used by the manufacturer or a result of the panel and software design. In practice, this means that scenes which the creators intended to leave in deep darkness can reveal more details than anticipated. Despite this, the image quality after calibration is clearly improved – warm, natural colours and realistic skin tones make viewing on the Bravia 8 II simply more pleasant to the eye.

All right, but you know we wouldn't be ourselves if we didn't also check how far we could push the S90H after professional calibration. And there was no big surprise. Since the factory settings were already very good, there wasn't much room for improvement. Even so, we managed to refine the picture to near perfection. After calibration the mean colour reproduction errors fell below the threshold of perception, with Delta E values under 2 for both SDR and HDR material. We also improved the brightness response, so the image more faithfully reflects the creators' intent and maintains appropriate tonality across the whole luminance range. After professional calibration the S90H therefore becomes a display very close to reference.

Will the difference be spectacular for everyone? Not necessarily. The factory settings already deliver a very high level, so in everyday viewing some people may not notice a dramatic jump. Much also depends on the individual unit. Our sample was very well tuned straight out of the box, but that doesn't mean every S90H will perform at the same level. Even identical models can differ from each other in terms of factory calibration. That's exactly why professional calibration makes sense: it allows a specific unit to be brought to the highest possible accuracy, rather than relying on a bit of luck when buying.

Upscaling and digital image processing are a true showcase of the capabilities of the Bravia 8 II. Sony has long been regarded as a master in this field, and here it only reaffirms its reputation. The proprietary XR processor can extract nearly the maximum from lower-resolution materials – whether it's television or an old DVD film, the image appears clearer, with more detail and better depth. Of course, if we feed it exceptionally low-quality material (like our archival photo with the Model), it won't work wonders, but in everyday viewing, it's hard to find fault with it.

The gentle gradation feature also performs excellently. In the "Medium" setting, it effectively smooths tonal transitions, eliminating banding in coloured and grey gradients, while not destroying the film grain or fine details in the image. It is this balance between subtlety and effectiveness that keeps Sony televisions among the best on the market in this category.

In this respect Samsung has changed practically nothing compared with last year’s model, which is actually quite good news. The feature responsible for smoothing tonal transitions still very effectively limits the posterisation effect. However, you should remember that it works rather aggressively, because besides the artefacts themselves it can also remove film grain and slightly soften fine image detail. As always, this is therefore a matter of compromise and personal preference. If you want the most faithful reproduction of the source material possible, we recommend leaving this function turned off.

There is also little to be said about upscaling in terms of revolution. The S90H uses the same proprietary NQ4 Gen3 image processor as its predecessor, so scaling quality has remained practically unchanged. The TV handles lower-resolution material well, effectively improving its sharpness. However, the overscan problem has still not been solved. With some older material, especially archival recordings, it may happen that a portion of the image at the edges is cropped. It’s a minor flaw, but a shame Samsung has left this issue unchanged for another year running.

The smoothness of motion is practically a closed topic in the case of the Bravia 8 II. The OLED with a refresh rate of 120 Hz naturally provides a very clear, sharp image in dynamic scenes, so it's hard to complain about anything here. However, one of the best motion smoothing systems on the market truly deserves special praise. They allow precise adjustment of film smoothness to one’s own preferences – from gentle smoothing to almost a “theatrical” effect – without the risk of artificial jumps, tearing of the image, or annoying artifacts. This is one of those features that will be appreciated both during movie screenings and while watching sports.

In terms of motion handling the S90H delivers a very high level. A new feature here is a panel with a refresh rate of up to 165 Hz, although in practice that will mainly benefit PC gamers. Films, series and sports broadcasts do not use such high refresh rates, so when watching them the difference compared with the standard 120 Hz will not be noticeable. That said, thanks to the OLED panel's lightning-fast response time motion is very clean and the picture does not suffer from the motion blur typical of many LCDs. Samsung has equipped the television with extensive motion-smoothness settings. You get two sliders: judder reduction and blur reduction, which let you easily tailor the picture's character to your own preferences. You can easily achieve a very smooth image when watching sport, but you can just as well preserve a more cinematic feel at the typical 24 frames per second. It all depends on which effect you prefer.

Sony has really learnt its lessons from previous years and in the Bravia 8 II has prepared a package of features for gamers that is hard to describe in any other way than "almost perfect". We have everything you'd expect from equipment of this class – VRR, ALLM, Dolby Vision Gaming mode, HGiG, and even a handy Game Bar that allows you to quickly preview parameters and change settings without leaving the game. It's also worth noting how smoothly and seamlessly these features work – no delays, no strange stutters. You simply start the game, and everything looks as it should. Unfortunately, there are a few "buts". The manufacturer still only provides us with two full-bandwidth HDMI ports, so if someone has a console, PC, and another device such as a soundbar connected via eARC, it becomes a hassle of switching cables. It is also surprising that there is no support for 1440p resolution at 120 Hz – particularly important for Xbox gamers. Overall, however – this is one of those televisions that can easily be placed in the centre of a gaming lounge and enjoyed without significant compromises.

From the outset the Samsung S90H feels like a TV designed with gamers in mind, and it's easy to see why. The manufacturer has equipped it with almost everything you could expect from a modern gaming screen. You get as many as four full-bandwidth HDMI 2.1 ports, support for ALLM and VRR, and very high refresh rates. There's also a clear Game Bar that lets you instantly check key picture parameters or change settings without leaving the game. Another very welcome improvement is the HGiG behaviour. Last year it could cause quite a few problems, but on the S90H it works exactly as it should.

Samsung's ace up its sleeve remains its proprietary Game Motion Plus mode. The feature works similarly to the motion smoothing used for films: it improves animation smoothness in games while keeping input lag at a very reasonable level. For titles running at 30 or 60 fps, with the right settings input lag did not exceed 40 ms in our tests. That's a very good result, especially since with many manufacturers enabling similar features results in delays several times higher. Game Motion Plus does not, of course, replace Dolby Vision Gaming, as it's a completely different type of feature, but overall it's a gaming addition that many players may find more noticeable. Smoother motion in 30/60 fps games often makes a bigger difference than HDR itself (which, incidentally, is often poorly implemented in games).
