Samsung QN990F vs SONY Bravia 9 II XR95M2

The Samsung QN990F belongs to the bright televisions category, and this is immediately evident in tests. In measurements, it achieved around 1300 nits, which in practice allows for enjoying films as their creators intended. Bright scenes have the right intensity, lights shine, and the experience is truly cinematic. In standard test patterns, sequences number 1, 3, and 5 performed best – there, brightness maintained around 800-1000 nits, and the image looked very natural. In more challenging segments, it could drop to around 600 nits, but even so, the level remained sufficient for details to be clearly visible. However, it should be added that in highly contrasting shots, the halo effect returns – the same one we mentioned regarding black levels. Bright elements can leave a halo on dark backgrounds, and this stands out immediately. Since we are dealing with a QLED, the colour palette is expanded, and the colours appear striking. The problem is that with such a flagship model, we expected better numbers. 91% DCI-P3 coverage and about 67% BT.2020 are results that can be considered solid, but not outstanding. This gives a vibrant and appealing image, yet the competition in this and lower price tiers can showcase even more.

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.

We tested the QN990F in Filmmaker mode, which is the best available right out of the box. Right from the start, we noticed several significant errors. The biggest issue concerned white balance. Due to too little blue, and also improper ratios between red and blue, the image – especially in scenes with a lot of white – appeared too yellow, and at times even orange. On the Color Checker palette, these errors didn't look dramatic as they hovered around a value of 4, but in everyday viewing, especially with strong whites, they were most noticeable. We also observed issues with brightness management – the television struggled to maintain detail in the smallest parts of the image, mainly due to the way it controls the backlighting zones. Fortunately, Samsung offers a lot of room for adjustment when it comes to calibration settings. We know that with the right calibration, much more can be extracted from this screen.

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.

After completing the calibration, we managed to bring the white balance back to order and eliminate the previous shortcomings in the shades of blue. As a result, the image no longer looked as if it had a slightly yellowish filter applied – the whites are purer, and the overall presentation is much more natural. We also managed, to some extent, to tame the brightness characteristics in HDR content. The television now handles detail retention in blacks significantly better and does not lose them to the same degree as before. However, when we look at the EOTF curve and the way the QN990F reproduces brightness in films, it is evident that it still tends to accentuate details in dark areas more strongly. This is a characteristic feature of Mini-LED technology and, more specifically, the way it is managed by the QN990F, which is practically impossible to completely eliminate. Despite this, after calibration, the image appears much more natural, mainly due to the correct exposure of white light. The final effect is definitely more pleasant to perceive and closer to what we expect from a flagship television.

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.

The biggest praise for the QN990F should be given for its upscaling. The processor responsible for "lifting" classic television to 8K resolution does quite well. While watching material in 576p signal, we had no illusions that we would suddenly see a miracle in advertising style, where the image magically transforms into crystal-clear 8K. Nevertheless, the end result was surprisingly good; the image looked clean and sharp. It’s just a shame that the television, like most Samsung models, has an overscan issue, slightly cropping the edges of the screen from the left side.

When it comes to image processing, Samsung offers a feature called "noise reduction," which in theory should improve tonal transitions in older materials, where they are usually more visible. Unfortunately, we felt quite disappointed here. The feature performs poorly – it does not handle unwanted stripes and can introduce its own artifacts. On the plus side, the television does not remove film grain when using this feature, but in practice, that is a poor consolation since the noise reduction itself proves to be virtually useless.

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.

QN990F can comfortably be called one of the fastest televisions in the world. In 4K mode, it is capable of displaying images at a frequency of up to 240 Hz, which until now has been more associated with gaming monitors than with televisions in the living room. However, in everyday viewing, what matters more is how it handles the 8K signal at 120 Hz – and here it performs very well too. Motion remains smooth, and the television manages without a hitch even with the most demanding content. Additionally, there is the motion smoother, i.e. "Picture Clarity". Thanks to it, one can adjust the image to their own preferences – leaving a slightly cinematic judder or switching to maximum fluidity, which works exceptionally well, for example, in sports broadcasts.

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.

It must be said outright – the QN990F is one of those televisions that practically scream that they were designed with gamers in mind. Samsung has been developing its gaming solutions for years, but here we have a truly comprehensive set. Sure, it lacks Dolby Vision support in games, which is a downside that will always come up in discussions. However, aside from that, the list of features is impressively extensive. To begin with, we have the Game Bar – a handy menu that allows you to quickly check and change gaming-related settings. You can see, for example, the enabled VRR, frame rate, or aspect ratio settings. It’s like a little “dashboard,” making it unnecessary to dig deep into the menu to make adjustments. Speaking of VRR: yes, variable refresh rate is present here and works flawlessly. And there's ALLM, which automatically switches the television to game mode as soon as the console is powered on. These may seem like small details, but together they make using the QN990F simply comfortable and hassle-free.

However, the most impressive aspect is the number of ports. Four wireless HDMI 2.1 ports are already great news, as there is no need to choose whether to connect the console, the amplifier, or perhaps even a PC. There’s ample space for everything here. And if we add another micro HDMI (which we recommend connecting directly to the console), hidden in the casing, we practically have five inputs in full 2.1 standard. Let’s also add support for high refresh rates – 120 Hz at 8K and even 240 Hz at 4K – and we get a television that not only keeps up with the new consoles but also feels ready for consoles that are not yet available.

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.
