Samsung QN90F / QN92F vs Blaupunkt UGC5500S

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.

Here, we won't beat around the bush either – if you're looking for a TV strictly for cinematic HDR experiences, you've come to the wrong address. The Blaupunkt UGC5500S unfortunately is not a machine designed for such challenges. This is primarily due to its very low brightness, which we measured during our tests. A result of around 250 nits on film screens speaks for itself. It's simply too little to even talk about any real HDR effect. To be honest, everything displayed here in this format can best be considered a slightly "boosted" SDR mode. We expected this because practically every device in this price range fails in this regard, but we feel obligated to warn you. Manufacturers love to boast about HDR compatibility stickers on the boxes, but in reality, this format simply doesn't exist here – it lacks the "fuel" of brightness.

The situation is made all the more difficult for Blaupunkt because we have a panel with a very basic DCI-P3 color gamut coverage of just around 80%. You won't find any advanced coatings that enhance these capabilities (like quantum dots), making scenes that are supposed to burst with richly saturated colors appear simply desaturated on this screen. Therefore, we have a concrete piece of advice for you: do not push the HDR mode on this model. If you have the option in the streaming app settings – just turn it off. Sticking with the classic SDR mode will ensure that the TV won't try to "enhance" something that it can't handle hardware-wise.

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.

We also took a close look at how Blaupunkt handles colors in movie mode, and here the situation is, to put it briefly, twofold. We must clearly separate what we see in the standard SDR format from what happens when HDR is turned on, as these are two completely different worlds. Let’s start with the better side of the coin. If you plan to watch classic television, YouTube, or older movies on this TV, you can count on really well-tuned colors. In our test sample, the white balance in movie mode was exceptionally accurate, which honestly surprised us. Of course, to not make it too rosy, we noticed some flaws. Looking at the gamma charts, we observed that the processor struggles with properly dimming the image in its brightest parts. Additionally, there is quite strong, at times too aggressive, red saturation, which resulted in noticeable errors in reproducing certain shades. Nevertheless, in general terms, the image in SDR is simply solid and watchable without a grimace on your face. Unfortunately, the magic fades when we re-enter the world of HDR. Here, Blaupunkt behaves as if we suddenly switched it to store mode, and in its worst form. The excess blue in the white balance is so overwhelming that it literally clashes with the eyes, ruining any realism of the scene. Furthermore, the TV interprets brightness very loosely, which, when analyzing the EOTF curve, clearly showed that for most of the time the colors appear simply washed out and lacking depth. This is, by the way, perfectly visible in the color errors that become evident in this mode. Once again, we are left with the same conclusion: Blaupunkt in SDR mode looks significantly better and more natural than in HDR, which feels forced and not properly refined.

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.

It may sound like a joke – pulling out professional measurement equipment for a television costing around a thousand zlotys / 250 dollars – but we wouldn't be ourselves if we didn't check it out. The question is: does such cheap equipment give us any room for calibration? To your surprise, the answer is yes, and absolutely so. In the Blaupunkt UGC5500S menu, we found surprisingly many options that allowed us to really work on the picture. These are not just empty sliders; they are concrete tools that enabled us to make use of our measurement sensors and software. In SDR mode, the effects were noticeable to the naked eye. We successfully eliminated the issue we mentioned earlier – that excessive, almost artificial saturation of reds. We also fixed the problem of incorrect dimming of the brightest parts of the image. After calibration, the standard format picture became much more balanced and simply correct. As for HDR, the situation was again more complicated. Although we managed to "tame" that aggressive blue tint in the white balance, it was evident that we were fighting a bit in vain. Even after changing the settings, the television still tried to intervene in the image in its own way, as if the electronics knew better than we did how the scene should look. Additionally, there's a hardware barrier that no slider can overcome – colors in HDR still remain unsaturated. This simply results from the quality of the panel itself; it physically cannot produce the most vibrant colors. To summarize this point: if any of you ask whether it’s possible to calibrate a television for "a thousand," we respond with full conviction: it is possible.

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.

If you expect that the processor in this model will magically "fix" the poor quality signal from cable TV or old films from YouTube, we must disappoint you. The capabilities of this television end with absolutely basic upscaling, which is simply stretching the image to a higher resolution. It does this correctly in that the image is not blurry, but there is no talk of any intelligent sharpening or adding details. Worse still, Blaupunkt is completely devoid of any functions that reduce unwanted tonal transitions. If the material being viewed has so-called banding (ugly "steps" instead of a smooth transition of colors, e.g., in the sky), this television will display them in all their glory. Additionally, the television tends to slightly crop the edges of the image. Instead of displaying 100% of what the source sends, Blaupunkt slightly enlarges the frame, causing us to lose details located at the very edges of the screen. In summary: in the category of digital "enhancement" of the image, Blaupunkt simply performs poorly. We receive a raw, unprocessed signal with all its flaws.

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.

When it comes to motion fluidity, Blaupunkt has nothing to defend itself with. A 60 Hz panel at this price is standard, so none of us expected a perfectly sharp image during fast action scenes or while watching a game. However, the biggest drawback of this model is that you won't find any digital smoothers in the menu. The manufacturer did not give us any room to maneuver – there's no way to smooth anything out or adjust the image to our preferences. The image is always "raw" and we receive it exactly as the source transmits it. For fans of cinematic "motion jump," this might be fine, but everyone else just has to get used to the absence of any motion support.

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.

When it comes to gaming on the Blaupunkt, we didn’t expect miracles and indeed – the list of features is not very long. However, there are two interesting points worth mentioning, as they may be significant for some of you at this price. The first advantage is that the TV quite efficiently detects the connected console. Thanks to the ALLM (Auto Low Latency Mode) feature, the device automatically knows when you start gaming and switches to low latency mode. This is convenient because you don’t have to fiddle with the settings every time to prevent input lag from ruining the fun. The second point is a real curiosity that surprised us. Even though it’s a 60 Hz panel, the Blaupunkt can display images at 120 Hz at Full HD resolution. Sure, we lose 4K details then, but for those playing more dynamic, online shooters where fluidity is more important than resolution, it’s a really nice and unexpected addition in such an inexpensive piece of equipment. Besides these two points, however, you won’t find anything else here. There are no advanced systems for improving fluidity for gamers or extensive gaming menu bars. It’s a simple screen for occasional gaming.
