Samsung Q8F vs Samsung QN90F / QN92F

In terms of brightness, the Samsung Q8F performs surprisingly well for a television without local dimming. It measures up to 500 nits, which practically means that most movie and series scenes look pleasant, and it definitely cannot be accused of lacking the "HDR effect." In films like Life of Pi or The Meg, the screen was able to glow and deliver light effects at a satisfying level. It struggles more during challenging moments—with dark frames containing single bright points. The global dimming used causes the television to darken the image to maintain deep blacks, but at the cost of detail brightness. This is clearly visible in the scene from Sicario 2, where the helicopter lights dropped to around 200 nits. This is a conscious design decision that gives the impression of deeper blacks but somewhat takes away from the brilliance of individual elements, and this should simply be kept in mind. When it comes to color reproduction, the Q8F utilizes quantum dot technology, which broadens the color range. A DCI-P3 coverage of 91% can be considered a decent result, although it is not a record-breaking achievement compared to other QLEDs.

The Samsung QN90F can truly shine in brightness. In our measurements, it achieved over 2200 nits, which directly translates to the viewing experience. Practically, this means that when a very bright scene appears in a movie – for example, the sunrise in The Meg – the screen looks as if natural light is actually shining on us. This isn’t just a number from a chart, but a real sense of image intensity! However, the TV cannot always deliver that full power. With smaller details, such as headlights or lamps, the brightness drops to 500–700 nits. This is a conscious decision by the algorithms – this way, the contrast between large and small elements is better controlled, and the image does not lose balance. Importantly, this is still a huge improvement compared to last year's QN90D, where similar details were almost invisible, shining at just 200 nits. Here, the HDR effect is much more consistent and credible. The only downside is the colors. The coverage of the DCI-P3 palette stopped at 91%, which can be considered a rather average result in this price range.

We decided to check the Filmmaker mode because it provided us with the best picture right out of the box. However, this does not mean it was perfect. The white balance had too much blue and red tint, causing the white to take on a slight purple-pink hue. Such an imbalance affected the visibility of practically all colors, as can be seen in the comparison photo below. The brightness characteristic in SDR content was quite well adjusted, although in HDR materials, we noticed that the television did not always manage its global dimming—at times, the screen was too dim, while at other times it suddenly brightened. Fortunately, issues related to colors can be effectively corrected with calibration tools, so we decided to get to work.

We tested color reproduction in the QN90F in Filmmaker mode, and as usual with Samsung TVs, this mode proves to be the best starting point right out of the box. However, this does not mean that the image is free from flaws. The white balance in SDR and HDR content was surprisingly good – the colors didn’t shift in any direction, and even in the factory setting, it looked solid. However, a problem arose with the gamma and EOTF curves, which are responsible for how the TV manages brightness. Here, the QN90F significantly brightened the entire image, causing black levels and colors to lose their intensity, and the overall effect resembled a milky filter being applied. Fortunately, Samsung, unlike many competitors in the miniLED world, provides users with a lot of tools to control the settings that we don’t find with other manufacturers, such as Chinese brands. Therefore, we decided to check if it was possible to extract the full potential of the QN90F because we know that such a high series can deliver much more.

After calibration, we managed to correct the white balance almost to perfection. Older SDR content looks stunning — most errors are within a threshold of 2, which is definitely below the human eye's perception limit. In HDR, we also brought the white balance to the correct level, but a different problem arises here. So why are there still relatively large errors in color reproduction? This is mainly due to the limited color palette and the way the television manages brightness. The applied global dimming technique does not give the user control in the settings, so when analyzing the EOTF curve in HDR films, it is clear that the Q8F can independently modify luminance. This can be considered a certain limitation, but despite this, the image after calibration is still much more enjoyable than in the factory version.

After our adjustment of the settings, the QN90F showed what it is really capable of – and it must be admitted that it has one of the best images we have seen on a miniLED screen this year. As we mentioned earlier, the white balance was not a major issue even in its factory version, but only after the gamma calibration were we able to get close to nearly reference values. The same is true for HDR content, where the EOTF curve after correction presents mature and consistent results. Indeed, in some films, it can be noticed that the smallest elements of the image are slightly brightened, and with a limited number of dimming zones, there is still a risk of the halo effect. It should be remembered, however, that such phenomena are characteristic of all miniLED televisions, and it's hard to expect miracles even from the QN90F. The most important thing is that after calibration, the television shows an image that, in terms of conveying the director's vision, confidently competes even with many OLED screens available on the market.

Let's see how the Q8F handles older content, which often has poor quality. Let's start with the positives: the upscaling, which means raising the image to a higher resolution, works really well. The TV handles both classic television and materials from YouTube without giving the impression that we are dealing with something completely unattractive. Materials in very low resolutions, such as 576p, perform worse — the image can be cropped, and unfortunately, the overscan phenomenon cannot be turned off. However, the digital processing itself looks worse too. The noise reduction function, instead of removing unwanted interference, smooths out almost everything: film grain (which is desirable for many viewers) disappears along with the texture of the image, and the faces of the actors begin to resemble characters from cheap Turkish soap operas. It is therefore hard to consider this option useful — it's best to leave it completely turned off. Perhaps Samsung will refine the operation of this feature in updates, but for now, it’s difficult to regard it as anything other than an unnecessary addition.

QN90F handles upscaling very well. Materials in lower resolution, even SD, are boosted to a clear and sharp image, showcasing plenty of details in the background. This is a significant advantage because the television makes older content or everyday TV look much better than on most budget screens. However, the issue of overscan remains, which is the trimming of the edges of the screen that cannot be turned off in Samsungs. This can cause some subtitles on the screen to disappear or a relative's face from a wedding on a VHS tape to be slightly cropped. 😉

The digital image processing also works well. In the menu, we find a feature called "noise reduction," which can smooth out tonal transitions and improve the reception of lower-quality materials, such as from YouTube. In medium setting, the effect is the most beneficial – it does not heavily interfere with details while eliminating the "stair-stepping" problem in colors. However, it is important to remember that the feature can be quite aggressive and can also remove natural grain in older films, so it's best to use it in moderation.

Due to the 60 Hz panel, it's hard to call the Q8F a television made for gaming or watching sports. The panel isn't particularly fast, making motion blur clearly visible. If you were counting on spectacular, almost "stadium-like" experiences during broadcasts, you might feel a slight disappointment. Fortunately, in the case of movies and series, Samsung has not abandoned motion smoothing features. This is nothing other than a motion smoother that allows improving the fluidity of productions recorded at 24 or 30 frames per second. Thanks to this, one can decide whether they prefer a smoother, "television" image or to maintain a cinematic quality. It all depends on the viewer's preferences, and the ability to adjust this parameter is undoubtedly a plus.

The QN90F is equipped with a panel that has a maximum refresh rate of 165 Hz, and while primarily PC gamers will appreciate this advantage, it is still worth highlighting. In movies or sports broadcasts, we are limited to the classic 120 Hz, but this is not a cause for concern. In practice, the additional motion smoother plays a more significant role here. With the "Motion Clarity" setting, we can adjust the image to our own preferences. The blur reduction option is responsible for smoothness and trailing in sports. Meanwhile, the "judder reduction" function improves motion smoothness in productions recorded at 24 frames, such as movies and series. If we set it high, the film looks smoother and more fluid than it was actually filmed. Lower values, on the other hand, maintain its cinematic "rawness" with the visible film frame.

[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 not entirely clear what Samsung has mixed up this year with its televisions, but the Q8F is not free from all the confusion with updates and shortcomings. While its older cousin, the Q67D, could still be recommended to casual gamers with a clear conscience, it's hard to find a reason to do so here. Aside from the automatic game mode and the attractively designed Game Bar, we practically get nothing that could attract gamers. The lack of proper HGiG implementation is a big problem, especially since function simply disappeared after the 1126 update. The issue with VRR is even worse. Although it is featured in the manufacturer's brochures and appears in the Game Bar, we couldn't activate it. The Xbox Series X console did not allow it to be activated at all, and the option remained grayed out and inactive. It's hard to praise such a television even to casual gamers, which is a shame because Samsung has had a strong bargaining chip in the gaming segment for years.

QN90F has nearly everything to become the perfect television for gamers. Things like four HDMI ports, VRR, ALLM, and refresh rates reaching up to 165 Hz are probably well-known. It deserves high praise for the Game Motion Plus mode, which is a proprietary motion smoothing technology for games. Thanks to this, it can add a few “artificial” frames and make the image generated from the console look smoother than it should. This is a very unique solution in the world of televisions – competitive systems usually do not offer this – which is why Samsung has had a strong bargaining chip among gamers for years, even despite the lack of support for the still niche Dolby Vision in games.

[UPDATE] We have updated our tests of Samsung televisions from the 2025 model year due to the release of software version 1131, which restored the crucial gaming feature HGiG.

So why are we writing about a “nearly” perfect screen? Unfortunately, similar to recent Samsung models, we noticed an issue with the lack of the HGiG feature. This solution allows the television to leave control over tone mapping to the console, so that games look exactly as the creators intended. Worse still, this feature was previously present, and it disappeared after software updates. Instead of minor tweaks, we received a step back. It’s a shame because if it weren't for this absence, the QN90F could truly be the perfect choice for gamers in the miniLED category.
