Samsung QN900F vs Sony BRAVIA 2 II (S25M2)

QN900F is a seriously bright TV – it can generate nearly 2000 nits, which is a level that remains unattainable for most models on the market. But the ability to achieve such brightness isn’t everything – it also matters whether the TV can make good use of it. And here it’s not always perfect. Our tests on cinematic scenes showed that in scenes like those from Life of Pi or The Meg, the QN900F can really shine – both literally and figuratively. In such moments, its greatest advantage, which is brightness, makes a huge impression. However, in more demanding scenes, things start to get tricky – similar to assessing contrast. When smaller, bright elements appear on the screen, the TV often struggles with the decision of whether to highlight them at the cost of black levels or perhaps maintain deep blacks but tone down the brightness. The result is situations where, for example, in the movie Sicario 2, the brightness dropped to just 200 nits, making details barely visible. The dimming algorithms could definitely be better, considering the class of this television.

Sony Bravia 2 II isn't a particularly bright TV and unfortunately that's immediately obvious in HDR. In our measurements brightness stayed around 300 to 330 nits, which is far too low for the brightest parts of the image to look truly impactful. In practice HDR here doesn't differ that much from regular SDR. Bright highlights, the sun or lamps are of course visible, but they lack the intensity you'd expect from HDR content. The Bravia 2 II is therefore much better suited to standard SDR material, where its limited brightness will be least noticeable.

Colour gamut coverage

The Sony Bravia 2 II also doesn't impress when it comes to colour. The TV doesn't use any extra gamut-expanding filter, such as the quantum dots found in QLED sets or a PFS phosphor layer. In our measurements it covered about 78% of the DCI-P3 gamut and roughly 57% of the very wide BT.2020. That's definitely too little to deliver truly saturated colours in HDR material. More intense reds, greens or turquoises will simply be less striking than on TVs with an expanded colour gamut. The Bravia 2 II is much better matched to the standard Rec.709 gamut used for films, series and SDR broadcast.

Testing the QN900F in Filmmaker mode, the distinct characteristics of the image quickly became apparent, despite this mode being designed to reflect the director's vision. The white balance was not perfect – the television had noticeable deficits in blue. This caused the entire scene to take on a warmer tone, as if someone had applied a subtle filter in shades of yellow and orange to the image. In films where bright shots dominate – for example, scenes in the snow or under strong daylight – this gave an impression of a slight warmth that does not always convey the director's intention. The second noticeable element was the management of brightness. The QN900F sometimes brightened the image more than necessary. It looked as if the exposure had been slightly "pushed up," which caused the scene to lose some naturalness. Shadows could be too shallow, and contrast slightly weakened. These are not disqualifying errors, but for a television in this price range, it is clear that the Filmmaker mode has not been perfected one hundred percent. This is particularly noticeable when we compare its image to what was visible after the screen calibration.

The out-of-the-box colour reproduction in Kino mode was really quite good, at least for ordinary SDR material. The Bravia 2 II had a slight tendency to boost reds, which made some colours lean a bit warmer, at times with a faint pinkish tint. That wasn't a major fault and during normal viewing the picture still looked fairly natural. There was a bit more going on with image brightness. Looking at the gamma curve, Sony doesn't stick perfectly to the reference value. The darkest areas are slightly lifted, while as brightness increases the gamma gradually rises and a large part of the image becomes darker than it should. However, the difference isn't big enough to seriously bother during everyday watching. Overall, SDR straight out of the box performs quite decently.

The situation is much worse in HDR. We've already mentioned the limited colour gamut, but on top of that the Bravia 2 II quite aggressively manipulates image brightness. The EOTF curve sits below the reference for much of the range, which means the TV renders most mid and brighter parts of the scene darker than the source material intends. Only towards the very end of the range does the curve flatten out, as the panel reaches the limits of its capabilities. Combined with a peak brightness of around 300 nits, this gives HDR that not only lacks much punch but can simply look too dark.

After calibration, we managed to reduce the errors in white balance and adjust them to a level that can be considered acceptable. It's not perfect, but definitely better than the factory settings. Most colour errors now fall within the deltaE 2–3 range, so in practice, they shouldn't be noticeable during everyday viewing. The biggest improvement is evident in how the television handles brightness in SDR content. Shadows and details are no longer flattened, giving the image depth and naturalness. As for 4K HDR materials – colours themselves are no longer an issue, but one can still notice some imperfections in Mini-LED technology. The QN900F tends to excessively dim the smallest bright elements, causing them to sometimes disappear from view. However, it's worth noting that this is a much better solution than boosting the entire screen, which would ruin the contrast. This is more of a characteristic of the technology rather than a typical flaw, but it's worth keeping in mind. The effects of the calibration are really very good.

Calibration did a lot for the Bravia 2 II, especially with SDR content. Above all, we managed to even out the white balance and tidy up the gamma, which now stays much closer to the reference value. As a result, the image no longer has the earlier pink cast, and the brightness across different areas is much better organised. You can also see it in the colour errors, which after calibration dropped to a very low level (with only minor issues in the most saturated reds).

We also partly managed to rein in the Bravia 2 II in HDR, especially in the way the TV handles image brightness. However, there is one thing no calibration can fix: the panel's capabilities. A narrow colour gamut means the TV physically can't reproduce the most saturated colours recorded in HDR content. On top of that, the low contrast of the IPS panel causes darker scenes to be covered in a grey haze, which robs colours of some of their depth. So we can improve how the Bravia 2 II uses its capabilities, but we can't overcome the panel's inherent limitations.

If we want to get rid of awkward tonal transitions that can be annoying, for example, while watching YouTube, we can use a feature called noise reduction. It works really effectively – it eliminates issues with colour blending when set to Standard level. However, as with most Samsung TVs, this comes with some compromises. Although we didn't notice this feature having a significant impact on the structure of objects in the image, it unfortunately reacts quite aggressively to film grain. Most people will likely appreciate this effect – the noise is simply removed – but if someone is looking for an image as close as possible to reference settings, we definitely recommend turning this option off.

When it comes to upscaling, or dealing with very low-quality content, the QN900F performs really well. On the test pattern with a model, the image looked clear, with only slight jaggedness that shouldn't bother most viewers. However, it’s worth mentioning one issue – the TV sometimes struggles with so-called overscan, which means older content may be slightly cut off. This can manifest, for example, with disappearing subtitles at the bottom of the screen.

Upscaling on the Bravia 2 II performs quite well and the TV maintains the standard we've come to expect from Sony. Lower-resolution material is sensibly upscaled to 4K, and the image is slightly smoothed without excessive edge sharpening. It's less successful at dealing with content that shows visible compression artefacts. That's down to the "Digital Noise Reduction" function, which on the "High" setting can smooth some ugly banding. The problem is it does so quite aggressively and, along with the imperfections, removes a lot of fine detail, including natural film grain. What's more, when there's more motion on screen its effectiveness drops considerably and the improvement is minimal. For that reason we generally didn't use this feature for everyday viewing.

There’s really nothing to nitpick here – the QN900F looks great when it comes to motion. Thanks to its 165 Hz panel in 4K, you can confidently say that this TV is suited for both watching sports and gaming. The motion smoother plays a key role here. It works brilliantly – not just with sports broadcasts, where it can eliminate blurring and image judder, but also in games, where animation becomes clearer and more fluid. And of course, if someone likes to experiment with movies – they have that option as well. At lower settings, you can see a slight graininess and a filmic quality, while higher settings introduce a soap opera effect. So everyone can tailor the picture to their preferences, and the TV has the power to handle it.

Bravia 2 II uses a 60 Hz panel and, for what it is, handles motion quite well. However, bear in mind it’s an entry-level panel and its limitations are especially noticeable with sports. The TV can’t interpolate 50/60 fps material to a higher refresh rate, so it can’t further improve the sharpness of fast-moving objects. For films and series there’s a conventional motion-smoothing feature that can reduce the judder typical of 24 fps material.

[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.

It's really good here. The QN900F offers a full set of features that we would expect from a top-notch gaming TV – we have VRR, ALLM, Game Bar, as well as cloud gaming apps. However, the biggest standout is its proprietary motion smoother, which also works in games and – importantly – does not add noticeable input lag. This is something we won't find in other competitors. Unfortunately, there is also something concerning. This year, Samsung has clearly messed up something with its TVs. During the testing of the QN900F before its update, it had the HGIG feature, which allowed for perfect adjustment of HDR settings for consoles. However, according to our procedures, we always update the hardware to the latest version – to give the manufacturer a chance to fix any issues. And here… it went the other way.After the update, the HGIG feature disappeared from the menu, making proper configuration of the console for HDR practically impossible. It was supposed to be complete – 165Hz, four HDMI 2.1 ports, a full gaming package… but unfortunately, it turned out to be a little mishap. What a shame.

The Bravia 2 II isn’t a TV that’s particularly suited to gaming, and the feature list makes that clear pretty quickly. You basically only get automatic low-latency ALLM and a simple Game Bar where you can view basic signal info and change a few settings. That’s where the positives end. The TV doesn’t support VRR or 120 Hz (not even at lower resolutions) and on top of that it has problems correctly implementing HDR HGIG. It’s fine for occasional console play and, thanks to low input lag, the controls remain responsive, but if you’re after a TV primarily for gaming the Bravia 2 II is a significantly limited choice.
