Samsung S90H (QD-OLED) vs SONY Bravia 9 II XR95M2

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.

The real showcase of the new backlight architecture and Sony’s processor is HDR material reproduction. At the official launch Sony engineers said (not officially 😉) that the brightness of the Bravia 9 II should be almost identical to their professional director’s monitor BVM-HX3110, which is priced at astronomical sums. Our lab tests confirmed those were not empty promises. During synthetic measurements on the L20 test pattern the TV effortlessly exceeded the 4000 nits peak brightness barrier. Most importantly, these spectacular results translate directly to real film scenes. In most of the demanding shots we tested the screen easily maintained brightness around 2500–3000 nits. Regardless of the scene’s character, whether the light was small and pinpoint or flooded almost across the entire screen, the HDR effect was incredibly intense.

Colours

Colours are another key pillar of RGB Mini LED technology (Sony’s True RGB implementation). Specifically for testing these kinds of displays we have permanently introduced a new research section to examine how TVs handle colours in real-world conditions. Traditional tests using synthetic patterns are no longer enough to determine actual colour-gamut coverage. From now on we also measure colour saturation directly in selected film scenes by overlaying measurement points on them. So how do the colours perform?

In synthetic tests the Bravia 9 II achieves excellent results. For the popular DCI-P3 space used for HDR content the colour gamut coverage reached almost 98%, while for the extremely wide and demanding BT.2020 space measurements indicated nearly 90%. However, in real, varied scenes those values fall by a few percentage points. This is a direct result of the nature of zoned RGB backlighting. When differently coloured elements or bright white highlights appear side by side, light from adjacent zones starts to bleed together, producing a slight whitish glow. That naturally affects colour saturation, reducing it slightly. It shows that despite Sony’s brilliant algorithm for controlling the RGB LEDs, the number of zones is still too small to eliminate this effect entirely.

Is that something to complain about? Of course not. The Bravia 9 II’s final colour coverage is ultimately the same as that of a very good QLED TV, and the most important point is this: the vast majority of HDR films and series are distributed in the DCI-P3 colour space. In that standard Sony easily maintains very high colour saturation, regardless of the scene.

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.

Contrary to appearances and high expectations, the Bravia 9 II we tested showed some issues with its factory calibration straight out of the box. Looking at the white balance charts, it’s clear it wasn’t perfect. In SDR content the red component was noticeably lacking, so the image leaned toward cooler, bluish tones. In HDR, however, the white balance in that respect was considerably better. So where do the visible errors in image reproduction come from? They result from unexpected tuning of the gamma and the EOTF curve. In both cases the Bravia 9 II straight from the factory showed a marked deviation from reference standards. In SDR material the gamma was significantly too high — at extremes it hovered very close to 2.8 instead of the target 2.4. In practice this meant the image looked artificially darkened and seemed washed of colour, with details in darker areas (the shadows) disappearing entirely. The opposite happened with HDR material, where brightness reproduction is governed by the EOTF. That curve was pushed too high above the correct value, causing the image to be artificially brightened across most luminance ranges. As with every TV we test, we subjected this unit to professional calibration. You can see the results and how we managed to correct these factory errors below.

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.

Fortunately, with professional calibration, most of the Bravia 9 II’s factory missteps can be effectively eliminated. We managed to precisely correct, above all, the white balance and the gamma curve and EOTF. After these procedures, in everyday use and during film viewings the television looks worlds better. The picture gained proper depth and modelling, the cool tint to whites disappeared, and shadow detail that previously vanished because of an overly high gamma finally became perfectly visible. Although we ultimately rate colour accuracy as very good, as specialists we must point out one fairly serious design flaw in this model. The Bravia 9 II could look even better if it were not for the complete lack of an advanced colour management system in the television’s menu.

While a basic white balance correction can be carried out here without difficulty, the settings lack options for adjusting specific colours. We tried to tackle this issue in every possible way, both with the traditional method from the remote and via dedicated calibration software for Bravia televisions. Unfortunately, that function has been completely locked. We suspect this may stem from the specifics of the new RGB architecture, which imposes its own limitations. It’s a great shame, because without it you cannot push colour reproduction to perfection. A skewed red still catches the eye. One can only hope that Sony will fix this shortcoming in time via an update.

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.

Digital processing and upscaling have long been Sony’s hallmark, and after testing the Bravia 9 II we can confidently say that nothing has changed in that respect. Sony remains at the forefront of the market. Their proprietary XR image processor, which in this model works alongside the main MediaTek Pentonic 1000 chip, deserves the highest praise. That combination delivers excellent results. The upscaling of lower-resolution material itself is extremely effective and precise. However, what most deserves applause in the XR processor’s operation is its tonal transition smoothing function. The system can reduce posterization in heavily compressed material to virtually zero. Crucially, the algorithm does this in a very intelligent way. It removes only the annoying digital “steps” in gradients without blurring fine texture details or creating an artificial, “plastic” look stripped of film grain. The picture remains sharp, natural and cinematic.

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.

In the Sony Bravia 9 II specification you won't find very high screen refresh rates above 120 Hz, which some more demanding PC gamers may regard as a drawback. However, in everyday use, whether during movie viewing, console gaming or watching sport, it's really hard to have any complaints about motion smoothness. The VA-type panel used here does show slight smearing, natural for this panel type, but the excellent Motionflow motion smoothing algorithms come to the rescue. In the system menu you'll find sliders for blur reduction and smoothing that let you precisely tailor the motion characteristics to your own preferences.

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).

Aside from a fairly serious design misstep in limiting the platform to just two full HDMI 2.1 ports, the Bravia 9 II offers almost all the key gaming features available on the market. Sony has already accustomed us to such a rich feature set in its previous models. The list of supported technologies is extensive. It includes automatic low-latency mode (ALLM), variable refresh rate (VRR), and a fully correct implementation of the HGIG standard and the Dolby Vision format tailored for gamers.
