Blaupunkt UGC5500S vs Samsung S90H (WOLED)

We won’t beat around the bush here – if you’re looking for a TV strictly for cinematic HDR experiences, then you’ve come to the wrong place. Unfortunately, the Blaupunkt UGC5500S is not a machine built 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 movie screens speaks for itself. It’s simply too little to even consider any real HDR effect. To be honest, everything displayed in this format can confidently be seen as a somewhat “enhanced” SDR mode. We expected this, as practically every device in this price range falls short in this area, but we feel it’s our duty to warn you. Manufacturers love to brag about HDR compatibility on the boxes, but in reality, this format simply doesn’t exist here – it lacks the “fuel” in the form of brightness.

The situation is further complicated for Blaupunkt, as we’re dealing with a panel that has very basic coverage of the DCI-P3 colour gamut, reaching only about 80%. You won’t find any advanced coatings to expand these capabilities (like quantum dots), which means scenes that are supposed to burst with richly saturated colours appear simply underwhelming on this screen. Therefore, we have a particular piece of advice for you: don’t force HDR mode on this model. If you have the option in the streaming app settings – just turn it off. By sticking to the classic SDR mode, you’ll be sure that the TV won’t try to “enhance” something that it can’t handle hardware-wise.

The Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price bracket, although it is slightly dimmer compared with the QD-OLED version. That difference is not as pronounced as in last year’s F series, where gaps sometimes reached 500 nits. Here the parameters of both panels are very similar, with differences in peak brightness of only about 100–150 nits. In small-window measurements the S90H with the WOLED panel easily reaches close to 1,500 nits. That headroom lets it phenomenally convey the dynamics of HDR effects — blooms, light reflections and explosions have the right punch, exactly as intended by the studio creators. As with most OLED displays, when a very bright scene fills the entire screen, panel protection systems kick in and brightness naturally falls to around 700 nits. It’s worth stressing that this is still an excellent result on the market, often noticeably better than many Mini LED screens in the same segment.

Colour gamut coverage

The biggest difference between the two S90H variants lies in colour reproduction and saturation. This stems directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a result, very high-brightness colours don’t achieve quite the same saturation, and the wide-colour volume is slightly more limited than with QD-OLED. That said, in everyday use these differences will be hard for most viewers to notice. Our measured DCI-P3 coverage on the WOLED panel reaches almost 99%, meaning that for the vast majority of real film scenes both variants will present an almost identical image. The real gap only appears in rarer, especially demanding productions that use the ultra-wide BT.2020 gamut. Because of the WOLED panel’s construction, coverage of that standard is roughly 15% lower compared with the S90HAT with a QD-OLED panel, so the brightest, heavily lit HDR colours may appear a touch less vivid.

We also took a close look at how Blaupunkt handles colours in movie mode, and here the matter is, to put it simply, twofold. We must once again clearly separate what we see in the standard SDR format from what happens when HDR is switched on, as they are two completely different worlds. Let's start with the better side of the coin. If you're planning to watch traditional TV, YouTube, or older films on this television, you can count on really well-tuned colours. In our test sample, the white balance in movie mode performed exceptionally well, which honestly surprised us. Of course, to avoid being too rosy, we noticed some drawbacks. Looking at the gamma charts, we observed that the processor struggles with properly dimming the image in its brightest areas. Additionally, there is quite a strong, at times overly aggressive, red saturation, which resulted in visible errors in reproducing certain shades. Despite this, overall, 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 rendition. The excess blue in the white balance is so significant that it’s glaring, ruining any realism in the scene. Furthermore, the television interprets brightness very loosely, which, upon analysing the EOTF curve, clearly showed that for most of the time, colours simply appear washed out and lacking depth. This is also perfectly evident in the colour errors that become apparent 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 seems to be forcefully added without proper refinement.

In Filmmaker mode, which we strongly recommend switching on straight out of the box, the S90H offers very good factory colour tuning. Colours are natural and faithful to the creators' intent, without the annoying oversaturation seen in more aggressive profiles. However, as is often the case without full calibration, there is unit-to-unit variation. In our test the white balance was a little deficient in the blue component, so the image leaned slightly towards warmer, yellowish tones. This was most noticeable in bright scenes, such as the snowy sequences from Star Wars. Additionally, the gamma curve was slightly low at around 2.2, which caused a small lift in shadow detail. In HDR mode the tuning was a bit better, showing only a slight undersaturation in the red region.

It may sound like a joke – pulling out professional measuring equipment for a TV that costs around a thousand złoty / 250 dollars, but we wouldn’t be ourselves if we didn’t check it. The question is: does such cheap gear give us any leeway in terms of calibration? To your surprise, the answer is: yes, absolutely. In the Blaupunkt UGC5500S menu, we found surprisingly many options that allowed us to effectively work on the picture. These aren't just empty sliders; these are concrete tools that enabled us to make use of our measurement sensors and software. In SDR mode, the effects were visible to the naked eye. We successfully eliminated the problem we mentioned earlier – that excessive, almost artificial saturation of reds. We also fixed the issue with the incorrect dimming of the brightest parts of the image. After calibration, the picture in standard format became significantly more balanced and simply correct. When it comes to HDR, the situation was more complicated again. While we managed to “tame” that aggressive blue tint in the white balance, it was clear that we were fighting a bit of a losing battle. Even after changing the settings, the TV still tried to interfere with the picture in its own way, as if the electronics knew better than we did how the scene should look. To top it off, there's the hardware barrier that no slider can overcome – colours in HDR still remain undersaturated. This simply results from the quality of the panel itself; it physically cannot produce the most vivid colours. To summarise this point: if any of you ask whether it’s possible to calibrate a TV for “a grand”, we respond with complete conviction: it is possible.

After full calibration, you can safely say the S90H in the WOLED version looks almost perfect. In SDR mode colour errors fall to ultra-low levels and Delta E values very rarely exceed 2. That's a phenomenal result, so if perfectly faithful colour reproduction matters to you, it's definitely worth getting it calibrated. The calibrated HDR mode also performs very well, where the white balance was stabilised and previous deviations eliminated. After professional tuning it's really hard to fault anything, because the TV delivers an image with almost exemplary naturalness and three-dimensionality. The slightly lower score in this category compared with the QD-OLED variant is solely due to the saturation limitation in extremely bright scenes, while the tuning potential and colour fidelity are at the highest level.

If you're hoping that the processor in this model will magically "fix" the poor quality signal from your cable TV or old movies from YouTube, we must disappoint you. The capabilities of this television end at 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 mention of any intelligent sharpening or adding details. Worse still, Blaupunkt is completely devoid of any functions to reduce unwanted tonal transitions. If the material being viewed shows what is known as banding (ugly "steps" instead of a smooth transition of colours, e.g., in the sky), this television will display them in all their glory. Additionally, the television has a tendency to slightly crop the edges of the image. Instead of displaying 100% of what the source sends, Blaupunkt slightly zooms in on the frame, causing us to lose details that are 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.

When it comes to banding reduction itself, Samsung has kept the same solutions known from last year’s models. The dedicated gradient-smoothing function works quite well and can effectively mask unwanted tonal transitions, which can be useful on a WOLED panel that’s somewhat more prone to banding. However, it’s important to remember it acts aggressively. This mechanism, aside from the artefacts themselves, can remove fine film grain and subtly soften detail. Ultimately it’s a trade-off, but if you want perfectly faithful image reproduction, it’s safer to leave this option off.

There’s also no breakthrough in scaling. The S90H uses the same NQ4 Gen3 processor as its predecessor, so upscaling quality was almost identical. The chip sharpens lower-resolution material very well, pulling a satisfying level of detail out of it. However, Samsung still hasn’t solved the old overscan problem. For some older recordings or archival footage the edges of the image can be slightly cropped. It’s a minor drawback, but it’s a shame the manufacturer still hasn’t fixed it.

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 in fast action scenes or during a match. However, the biggest drawback of this model is that you won’t find any digital motion smoothers in the menu. The manufacturer hasn’t given us any room for manoeuvre – nothing can be smoothed out or the image adjusted to our personal preferences. The picture is always "raw" and we receive it exactly as it is transmitted by the source. For fans of cinematic "jumping" images, this might be good, but the rest simply has to get used to the lack of any motion enhancement.

When it comes to motion handling the S90H is simply excellent. This year's panel offers its refresh rate boosted to 165 Hz, although in practice the benefit will mainly be for gamers connecting a powerful PC. For movies, TV series or sports broadcasts such a high refresh rate makes no difference and the picture looks exactly the same as at the standard 120 Hz. Regardless of the source, the OLED panel's lightning-fast response time does the job. Motion is clean, and the ghosting or smearing seen on LCDs simply doesn't occur here.

When it comes to gaming on the Blaupunkt, we weren’t expecting miracles and indeed – the list of features isn’t very long. However, there are two interesting points worth mentioning, as they might be significant for some of you at this price. The first advantage is that the TV quite smoothly detects the connected console. Thanks to the ALLM (Auto Low Latency Mode) feature, the device knows when you start gaming and automatically switches to low latency mode. This is convenient because you don’t have to fiddle with settings every time to ensure input lag doesn’t spoil the fun. The second point is a real curiosity that surprised us. Despite it being a 60 Hz panel, the Blaupunkt can display a 120 Hz image at Full HD resolution. Sure, we lose 4K details, but for those playing more dynamic, online shooters where smoothness is more important than resolution, this is a really nice and unexpected addition in such an affordable device. Other than these two points, you won’t find anything more here. There are no advanced smoothness enhancement systems for gamers or extensive gaming menu bars. It’s a simple screen for occasional gaming.

Gamers should feel right at home with the S90H, because Samsung has left few reasons to complain in this area. The TV has four HDMI 2.1 ports, each supporting VRR, ALLM and high refresh rates. There's also the Game Bar, a handy menu that lets you quickly check key parameters and change settings without leaving the game. Importantly, Samsung has also improved HGiG. In last year's models it could cause issues when used with a console, but on the S90H it now works as it should. What really stands out against the competition is Game Motion Plus. It's a specialised motion-smoothing mode for games that works best with titles running at 30 or 60 frames per second. Motion becomes noticeably smoother and latency remains at a reasonable level. In our measurements it was under 50 ms, so gaming is still comfortable. That's important, because on many TVs enabling a similar smoothing feature causes such a big increase in input lag that controls become noticeably sluggish. Samsung has managed to find a good compromise here. There's still no Dolby Vision Gaming, but in practice Game Motion Plus may prove to be the more useful feature.
