Samsung QN900F vs Samsung Q7F

QN900F is truly a bright television – it can generate nearly 2000 nits, a figure 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 television can make good use of it. And here, it is not always perfect. Our tests on cinematic test patterns showed that in scenes such as those from Life of Pi or The Meg, the QN900F can truly shine – literally and metaphorically. In such moments, its greatest advantage, which is brightness, makes a huge impression. However, in more demanding scenes, challenges arise – similar to when assessing contrast. When smaller, bright elements appear on screen, the television often struggles with the decision: should it highlight them at the expense of black levels, or perhaps maintain deep blacks while toning down brightness. The result is situations where, for example, in the film Sicario 2, brightness dropped to just 200 nits, making details barely visible. Dimming algorithms could definitely be better for a television of this class.

Unfortunately, the Samsung Q7F is not one of the brighter televisions, and this has a direct impact on the quality of HDR films. The peak brightness of the panel is just around 250 nits, which is definitely too low to speak of true cinematic experiences. In practice, the image in HDR content does not differ significantly from classic SDR, making it difficult to talk about any "wow effect" that usually accompanies us when watching such films. During tests of film scenes, the image simply looked dark, and the brightness almost always hovered around the aforementioned 250 nits. The worst performances were with shots that included small, intensely shining elements – the global dimming technique used reacted very aggressively in these cases, dimming the entire screen to maintain the effect of black. However, it is worth noting the presence of the QLED coating that expands the colour palette. For a budget QLED model, the Q7F performs quite decently here: the coverage of the DCI-P3 palette is about 93%, and BT.2020 reaches 70%. This means that, despite the low brightness, the colours can still look quite vivid and attractive.

Testing the QN900F in Filmmaker mode, the characteristic features of the image were quickly noticeable, even though this mode is designed to reflect the director’s vision. The white balance was not perfect – the television displayed distinct deficiencies in the blue colour. 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 films where bright shots dominate – for example, scenes in the snow or in strong daylight – this gave the impression of slight warmth that did not always convey the director's intent. The second noticeable element was the management of brightness. The QN900F could sometimes brighten the image more than necessary. It looked as though the exposure had been slightly 'pulled up', causing the scene to lose its naturalness. Shadows were sometimes too shallow, and the contrast 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 noticeable when we compare its image with what was seen after the screen calibration.

The factory colour accuracy of the Samsung Q7F is certainly not one of its strong points. In Filmmaker mode, which theoretically should be the closest to neutral, the issue with white balance immediately stands out. There is too much red on the screen, while blue is lacking. The consequences of this are very easy to notice – white, instead of being neutral, takes on warm, almost slightly orange tones. In the long run, this makes the entire image look somewhat unnatural, and bright areas of the scene may seem unrealistic. The problems become even more evident in HDR content. The graphs show that the television has significant errors in the Color Checker palette, which translates to visible inaccuracies in the actual image. Practically, this means that the colours are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, losing their cinematic quality, while bright parts may appear dimmed. As a result, the image seems flattened, and contrast, instead of helping to bring out details, only highlights its own limitations. This is particularly frustrating in HDR material, where every detail matters. In scenes where there should be a subtle play of light and shadow, the Q7F either oversteps by brightening too much or conversely – suppresses elements that should draw the eye. This causes the image to lose its depth, and instead of cinematic realism, we have a rather simplified effect.

After calibration, we managed to eliminate errors in white balance and adjust them to a level that can be considered acceptable. It is not perfect, but it is definitely better than the factory settings. Most colour errors now lie within the deltaE 2–3 range, so in practice, they should not be noticeable during everyday viewing. However, the most significant improvement is evident in how the television manages brightness in SDR content. Shadows and details are no longer flattened, which gives the image depth and naturalness. As for 4K HDR material – colours themselves are no longer an issue, but some imperfections of 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 noted that this is a much better solution than boosting the entire screen, which would spoil the contrast. This is more of a characteristic of this technology than a typical flaw, but it is worth keeping in mind. The effects of calibration are truly very good.

After professional calibration, we managed to bring the Q7F into order – at least in terms of SDR content. The picture in this mode looks really good: the white balance has been set correctly, the colours appear natural, and errors in the colour palette have dropped to levels that are practically invisible to the eye. Gamma behaves exemplary, and the only minor drawback is a slight lightening of smaller elements, which results from the lack of local dimming. For everyday watching of television or films in standard quality, the Q7F performs surprisingly well.

It was significantly harder to tame HDR content. Despite adjusting the white balance, the television still heavily manipulates brightness, causing scenes to sometimes look unnatural – what should be subtly darker can be overly brightened, and bright areas of the picture can occasionally appear dimmed. The end result is better than in factory settings, but it is evident that the structural limitations of the Q7F do not allow for the full potential of HDR materials to be fully realised.

If we want to eliminate jarring tonal transitions that can be irritating, for example, while watching YouTube, we can use a feature called noise reduction. It works really effectively – it removes issues with colour blending when we set it to Standard level. However, as with most Samsung televisions, this does involve some compromises. Although we did not notice this feature significantly affecting 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 scaling, or dealing with very low-quality content, the QN900F performs really well. On the test card with the model, the image appeared clear, with only slight aliasing that shouldn't bother most viewers. However, it is worth mentioning one issue – the television sometimes has problems with so-called overscan, which can cause older content to be slightly cropped. This might manifest, for example, in subtitles disappearing from the bottom of the screen.

Upscaling and digital image processing on the Q7F is a bit of a sine wave. On one hand, we have really nice upscaling – weaker sources look better than one might expect. The image becomes clearer, sharper, and even older films or terrestrial television perform adequately. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… there are some issues. The television has a problem with overscan – part of the image is simply cut off, and it doesn't look very elegant. Additionally, we were let down by a feature called "noise reduction", which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it makes practically no difference – the banding in gradients is still there. It's a bit of a shame, as one could have expected more from a model that is aimed at users looking for a display for SDR content.

There really is nothing to complain about here – the QN900F looks very good in terms of motion. With a 165 Hz panel in 4K, it can confidently be said that this television is suitable for both watching sports and gaming. The motion enhancer plays a key role here. It works brilliantly – not only during sports broadcasts, where it can eliminate blurring and image shaking, but also in games, where the animation becomes clearer and smoother. And of course, if someone likes to experiment with films – they also have that option. At lower settings, a slight graininess and cinematic character can be seen, while at higher settings, it takes on a soap opera effect. In other words, everyone can adjust the picture to their preferences, and the television has the power to handle it.

Ghosting and motion smoothness in the Q7F are probably the most budget-friendly elements of this television. The 60 Hz panel makes itself known, with noticeable ghosting, especially in dynamic scenes, and it's rather difficult to regard this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, a long trail was left behind, similarly to how a ball in a football match would leave streaks.

On the plus side, the presence of motion smoothing must be acknowledged. In films, it actually makes a difference – especially since most material is recorded at 24 frames per second. Here we can decide whether we prefer a more "cinematic" image, with slight judder typical of cinema, or a smoother, more "television" approach. This part works quite well and helps to improve the viewing experience for series and films.

It really is nice here. The QN900F offers a full set of features that we would expect from a top-end gaming television – we have VRR, ALLM, Game Bar, and also cloud gaming applications. However, the biggest standout is the proprietary motion smoother, which also works in games and – importantly – does not introduce noticeable lag. This is something we won't find with its other competitors.

Unfortunately, there is also something concerning. This year, Samsung has evidently messed something up with its televisions. During the testing 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 – in order 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 correct 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 small blunder. What a shame.

Features for gamers in the Samsung Q7F is a topic that evokes quite a lot of mixed feelings. On the one hand – no sensible person expected miracles here, as it is after all a 60 Hz television and it was clear from the start that it would not be a device for squeezing the maximum out of a console or PC. On the other hand, since the manufacturer promised specific solutions in promotional materials, it is natural that we wanted to see them in practice. At the outset, it’s quite decent. The automatic game mode (ALLM) works, so there’s no need to manually fiddle with the settings; the console automatically switches the television to low-latency mode. Additionally, we have the Game Bar, which looks impressive and allows you to check a few basic parameters without leaving the game. And this is where the good news ends.

The biggest problem with the Q7F is VRR, or rather its absence. Yes, an appropriate icon appears in the menu, and you can even see it in the Game Bar, but throughout the entire test, the feature remained inactive and could not be enabled in any way. The situation with HGiG is even more painful; this option was indeed available at the beginning, but after a software update, it completely vanished, which is simply unprofessional. Therefore, the Q7F is only suited for the absolute basics. Of course, you can turn on the console, play some calmer titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television to buy with gaming in mind, and it's better to be aware of that before making a purchase.
