Samsung QN900F vs Hisense U7S Pro

QN900F is really a bright TV – it can generate nearly 2000 nits, which is a value that remains unattainable for most models available on the market. But the mere ability to achieve such brightness is not everything – it also matters whether the TV can use it well. And this is not always perfect. Our tests on movie scenes showed that in scenes such as those from Life of Pi or The Meg, the QN900F can truly shine – literally and figuratively. In such moments, its greatest advantage, which is brightness, makes a huge impression. However, in more challenging scenes, the issues begin – similar to assessing contrast. When smaller, bright elements appear on the screen, the TV often struggles with the decision: whether to highlight them at the expense of black levels, or perhaps maintain deep black but tone down the brightness. The result of this 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 for a TV of this class.

Let’s start by saying that the U7S Pro is an impressively bright television – in calibrated mode, our measuring equipment indicated a staggering 2200 nits of peak brightness! This is an impressive result, considering that this model is positioned as mid-range.

However, as we know, peak brightness on test patterns is one thing, and actual movie scenes are another. Unfortunately, in real video materials, the backlight power clearly drops. While in the most demanding moments the television can still exceed the 1000 nit barrier – which is still a great result, perfectly fitting the mastering standards of most HDR films – the truly challenging aspect turns out to be the aggressively tuned local dimming algorithms. Because of them, small, bright details, such as stars or the moon in the night sky, are noticeably dimmed. The television tries at all costs to maintain deep black levels, which is of course understandable, but unfortunately, this comes at the cost of dynamics and the brilliance of the HDR effect itself.

The color reproduction is worth praising. The new U7S Pro is a QLED construction that provides very wide color gamut coverage. Unlike last year's model (U7Q Pro), this year's variant is now a “true” QLED, rather than a solution based on a PFS filter. As a result, color saturation has noticeably increased, and coverage of the most demanding BT.2020 space has exceeded the 81% barrier.

Testing the QN900F in Filmmaker mode, one quickly noticed the characteristic features of the image despite the fact that this mode is designed to reflect the director's vision. The white balance was not perfect – the television had noticeable deficiencies in blue color. This made the entire scene take on a warmer tone, as if someone had applied a subtle filter in shades of yellow and orange. In movies where bright shots dominate – for example, scenes in the snow or in strong daylight – this created a slight warming effect, which does not always convey the director's intent. The second noticeable element was brightness management. The QN900F sometimes managed to brighten the image more than necessary. It looked as if the exposure had been slightly "pulled up," causing the scene to lose its naturalness. Shadows were sometimes too shallow, and contrast was slightly weakened. These are not disqualifying errors, but for a television in this price range, it is evident that Filmmaker mode has not been perfected one hundred percent. This is particularly evident when comparing its image to what was visible after screen calibration.

We tested the U7S Pro model – as always – in the best factory-tuned picture mode, which is Filmmaker Mode. We can evaluate the displayed colors in two ways. The most disappointing was the profile intended for watching SDR content, such as traditional television, YouTube, and other less demanding materials. The picture was clearly too yellow, which turned out to be a direct consequence of a poorly set white balance. As our graphs show, there is a huge deficiency of the blue component here, which drastically affected the overall color temperature. This is clearly evident on the ColorChecker charts and the graphs of the color palette itself, where most samples veered toward yellow. Fortunately, the factory HDR mode performed significantly better – there, the color errors hovered around a Delta E value of 3, which is already a really solid result.

After calibration, we were able to eliminate 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 color errors are now within the deltaE 2–3 range, so in practice they shouldn't be noticeable during everyday viewing. The biggest improvement is seen in how the television manages brightness in SDR content. Shadows and details are no longer flattened, giving the image depth and naturalness. When it comes to 4K HDR materials, colors themselves are no longer an issue, but some imperfections of the Mini-LED technology can still be observed. The QN900F tends to dim the smallest bright elements too much, causing them to sometimes disappear from view. However, it should be added that this is a much better solution than boosting the entire screen, which would spoil the contrast. It's more of a characteristic of this technology than a typical flaw, but it's worth keeping in mind. The effects of calibration are really very good.

However, we know that the Hisense company can do much more – as previous generations have proven – which is why we simply couldn't leave the factory flaws of the U7S Pro model in everyday content. As always in such cases, we subjected the television to professional calibration. The conclusions? This process brought about a colossal change. After manually adjusting the white balance and compensating for the deficiencies in the blue component, the annoying yellow tint disappeared like magic. The white became naturally pure, and skin tones gained the proper, healthy hue. Importantly, the calibration not only tamed the capricious SDR mode but also allowed us to squeeze the maximum from the panel's potential, reducing the average color reproduction errors to values almost imperceptible to the human eye. The only thing we have to nitpick after the entire process is the very nature of the Mini-LED backlighting and its specific cooperation with the HDR signal. The aggressively tuned local dimming algorithms significantly interfere with the EOTF brightness curve. As a result, the backlighting does not always work perfectly with the creator's intent – depending on the scene being viewed, the curve can noticeably run either above or below the reference, which at times disrupts the perfect dynamics of HDR image.

If we would like to eliminate non-fluid tonal transitions that can be annoying, for example while watching YouTube, we can use a feature called noise reduction. It works really effectively – it removes the issues with color blending when we set it to Standard level. However, as with most Samsung televisions, this comes with compromises. Although we did not notice that this feature significantly affects the structure of objects in the image, it unfortunately reacts rather aggressively to film grain. Most people will appreciate this effect – the noise is simply removed – but if someone is looking for an image as close as possible to reference settings, then we definitely recommend turning off this option.

As for scaling, which means handling very low-quality content, the QN900F performs really well. On the test screen with the model, the image looked clear, with only slight aliasing that should not bother most viewers. However, it is worth mentioning one issue – the television has problems with so-called overscan, which can cause older content to be slightly cropped. This can manifest itself, for example, with subtitles disappearing from the bottom of the screen.

The digital processing of lower quality signals is at a very high level here, thanks to the MediaTek Pentonic 800 processor utilized in the U7S Pro. The upscaling itself, which is the TV's ability to enhance lower resolution signals to 4K, is also performing well. We did not notice any unnatural, sharp edges on the screen, and our test image with the model looked simply attractive.

There really isn't anything to complain about here – the QN900F looks very good when it comes to motion. Thanks to the 165 Hz panel in 4K, one can confidently say that this TV is suitable for both watching sports and gaming. The motion smoothness feature plays a key role here. It works remarkably well – not only during sports broadcasts, where it can eliminate blurring and image jitter, but also in games, where the animation becomes clearer and smoother. And of course, if someone likes to experiment with movies – they also have that option. At lower settings, there's a slight graininess and filmic character, while at higher settings, it reaches soap opera effect territory. So everyone can adjust the picture to their preferences, and the TV has the power to handle it.

The Hisense U7S Pro features a panel with a maximum refresh rate of 165 Hz in 4K, and in game mode, it can reach up to 330 Hz at Full HD resolution. However, it's important to note that these highest numbers have little significance in everyday use, as most content supports a maximum of 120 Hz (e.g., while gaming on a console). Nevertheless, the TV handles motion quite well and performs really decently for an LCD construction.

There's hardly anything to complain about regarding fluidity. In the menu, we find a motion smoothness enhancer called "Motion Enhancement," which hides two sliders: blur reduction and judder reduction. They allow for manual configuration of the smoothness enhancer, which works well for both movies and sports, effectively improving the raw television signal.

[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 is really nice here. The QN900F offers a full set of features that we would expect from a top-tier gaming television – we have VRR, ALLM, Game Bar, and also cloud gaming applications. However, the biggest highlight is the proprietary motion smoothing, which also works in games and – importantly – does not add noticeable delays. This is something we won't find in its other competitors. Unfortunately, there is also something concerning. This year, Samsung has apparently messed something up with its televisions. During the test of the QN900F before its update, it had the HGIG feature, which allowed for perfect adjustment of HDR settings for the console. However, according to our procedures, we always update the equipment to the latest version – to give the manufacturer a chance to fix any shortcomings. And here… it turned out the opposite. After the update, the HGIG feature disappeared from the menu, making the 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 blunder. Such a shame.

If you plan to connect a console or PC to the U7S Pro, you will be more than satisfied – this television is excellent equipment for gamers. Hisense didn't spare any expense and included 4 HDMI 2.1 ports with full bandwidth of 48 Gbps. You won't need to juggle cables, as each port will handle the full package of features. We have an automatic game mode (ALLM) and VRR, which works over a wide range from 48 Hz to a cosmic 330 Hz. Of course, those 330 Hz are currently just a gimmick for owners of powerful PCs, as consoles will still be limited to 120 Hz, but it's good to have that reserve for the future. The Game Bar also works very well during gaming. It's a handy menu bar for gamers, where you can quickly change the picture mode, turn on a crosshair in the center of the screen, and even change the aspect ratio to ultra-wide without going into the main settings of the television, which PC simulator fans will appreciate. The only downside worth noting is the incorrect implementation of the HGiG format in games. This means that the television ignores the instructions from the console regarding the image generated in HDR10 and constantly meddles with the image it produces, trying to "enhance" it in its own way. Because of this, the correct configuration of HDR in the console menu (where brightness is set on the logo/checkerboard) is somewhat complicated.
