Blaupunkt UGC5500S vs Samsung S90H (WOLED)

Here, too, we will not mince words – if you are looking for a television strictly for cinematic experiences in HDR, you have come to the wrong place. The Blaupunkt UGC5500S is unfortunately 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 scenes speaks for itself. It is simply too little to even talk about any real HDR effect. Quite frankly, everything displayed here in this format can be confidently regarded as a somewhat “enhanced” SDR mode. We expected this, as virtually every device in this price range falters in this area, but we feel obliged to warn you about it. Manufacturers love to boast about HDR compatibility with stickers on their boxes, but in reality, this format simply does not exist here – it lacks the “fuel” of brightness.

The situation is particularly difficult for Blaupunkt, as we are dealing with a panel that has a very basic coverage of the DCI-P3 colour palette, reaching only about 80%. You will not find any advanced coatings to extend these capabilities (such as quantum dots), which means that scenes that should ideally burst with richly saturated colours appear simply under-saturated on this screen. Therefore, we have a specific piece of advice for you: do not force the HDR mode on this model. If you have the option in the streaming app settings – simply turn it off. By sticking to the classic SDR mode, you can be sure that the television will not attempt to “enhance” something that it cannot handle hardware-wise.

Samsung S90H in the WOLED variant is still an exceptionally bright TV for its price bracket, although compared with the QD-OLED version it is slightly dimmer. The difference is not as significant as in last year’s F series, where the gap could reach as much as 500 nits. Here the parameters of both panels are very similar, and differences in peak brightness are only in the order of 100–150 nits. In small-area measurements the S90H on the WOLED panel easily reaches levels close to 1500 nits. Such a reserve of power allows HDR dynamics to be reproduced phenomenally; all highlights, light reflections and explosions have the necessary punch, exactly as the creators intended in the editing studio. As with most OLED displays, when a very bright scene fills the whole screen protection systems activate and brightness naturally falls to around 700 nits. It is worth emphasising 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 results directly from the different construction of the WOLED panel, which uses an additional white subpixel. As a consequence, colours at very high brightness do not reach the same intense saturation, and the volume of the wide gamut is somewhat more limited than in QD-OLED. That does not change the fact that in everyday use these differences will be hard for most viewers to spot. The DCI-P3 space we measured reaches nearly 99% on the WOLED panel, which means that in the vast majority of real film scenes both variants will present an almost identical picture. The true distance only reveals itself in rarer, exceptionally demanding productions that use the ultra-wide BT.2020 gamut. Due to the specifics of the WOLED panel’s construction, coverage of that standard is about 15% lower compared with the S90HAT with a QD-OLED panel, so the brightest, heavily lit colours in HDR may appear slightly less vivid.

We also took a close look at how Blaupunkt handles colours in movie mode, and here the matter is, in short, twofold. Once again, we need to clearly separate what we see in standard SDR format from what happens when HDR is turned on, as these are two entirely different worlds. Let’s start with the better side of the coin. If you plan to watch classic television, YouTube, or older films on this television, you can count on really reasonably well-tuned colours. In our test unit, the white balance in movie mode performed exceptionally well, which honestly surprised us. Of course, to avoid being overly optimistic, we did notice some shortcomings. Looking at the gamma charts, we observed that the processor struggles with appropriately dimming the image in its brightest areas. Additionally, there is quite a strong, at times excessively aggressive red saturation, which resulted in visible errors in reproducing certain shades. Nevertheless, in general terms, the image in SDR is simply solid and can be watched without a grimace on one’s face. Unfortunately, the charm disappears the moment we again enter the HDR world. Here, Blaupunkt behaves as if we suddenly switched it to shop mode, and in its worst version. The excess blue in the white balance is so significant that it is almost blinding, ruining any realism of the scene. Moreover, the television interprets brightness very loosely, which, when analysing the EOTF curve, clearly showed that for most of the time, the colours appear simply washed out and lacking in depth. This is, by the way, perfectly visible through the colour 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 lacking appropriate 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 irritating oversaturation found in more aggressive presets. However, as is often the case without full calibration, no two units are identical. In our test the white balance was slightly lacking in blue, causing the image to lean a little 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 2.2, which produced a minor lift in shadow detail. In HDR mode the tuning was somewhat better, showing only a slight undersaturation in the red region.

It may sound like a joke – pulling out professional measuring equipment for a television costing around a thousand złotys / 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 manoeuvre when it comes to calibration? To your surprise, the answer is: yes, and very much 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 specific tools that we could utilise using our measuring 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 red saturation. We also fixed the issue of improper dimming in the brightest parts of the image. After calibration, the standard format image became significantly more balanced and simply correct. When it came to HDR, the situation was again more complicated. While we managed to 'tame' that aggressive blue tint in the white balance, it was clear that we were fighting somewhat in vain. Even after adjusting the settings, the television still tried to interfere with the image in its own way, as if the electronics knew better than us how the scene should look. Additionally, there is a hardware barrier that no slider can overcome – colours in HDR still remain under-saturated. This is simply due to the quality of the panel itself; it physically cannot produce the most vibrant colours. To sum up this topic: if any of you ask whether it is possible to calibrate a television for a 'thousand', we answer with full conviction: it is possible.

After a full calibration it’s fair to say the S90H in WOLED guise looks almost perfect. In SDR mode colour inaccuracies drop to ultra-low levels and Delta E values very rarely exceed 2. That’s a phenomenal result, so if you care about perfectly faithful colour reproduction it’s definitely worth considering calibration. The calibrated HDR mode also performs very well, with the white balance stabilised and earlier deviations eliminated. After professional fine-tuning it’s really hard to find anything to criticise, because the TV delivers an image with almost reference-level naturalness and three-dimensionality. The slightly lower score in this category compared with the QD-OLED variant is solely due to the aforementioned limitation in saturation in extremely bright scenes; the tuning options and colour fidelity themselves are at the highest level.

If you expect the processor in this model to magically "fix" the poor-quality signal from cable TV or old films 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 adequately in that the image is not blurry, but there's no mention of any intelligent sharpening or adding details here. Worse still, Blaupunkt is completely devoid of any features for reducing unwanted tonal transitions. If the material being watched has what is known as banding (that is, ugly "steps" instead of a smooth transition of colours, e.g., in the sky), this television will display it in all its 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 enlarges the frame, causing us to lose details at the very edges of the screen. In summary: in the category of digital "enhancing" of images, Blaupunkt simply performs poorly. We receive a raw, unprocessed signal, with all its flaws.

In terms of posterisation reduction itself, Samsung has kept the solutions known from last year’s models. The dedicated gradient-smoothing function performs quite well and can effectively mask unwanted tonal banding, which is useful on a WOLED panel that is slightly more prone to banding. However, you should be aware of its aggressive behaviour. This mechanism, alongside the artefacts themselves, can clean up fine film grain and gently soften detail. Ultimately it is a matter of compromise, but if you want an absolutely faithful reproduction, it is safer to leave this option off.

Similarly, in the area of scaling it is difficult to call this a breakthrough. The S90H uses the same NQ4 Gen3 processor as its predecessor, so the upscaling quality was almost identical. The chip sharpens lower-resolution material very well, extracting a satisfying level of detail. Samsung still has not dealt with the longstanding overscan issue, though. With some older recordings or archive footage the edges of the image can be slightly cropped. It’s a minor flaw, but it’s a pity the manufacturer still hasn’t eliminated 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 were expecting an impeccably 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 has not given us any room for manoeuvre – nothing can be smoothed out or adjusted to our personal preferences. The image is always "raw," and we receive it exactly as the source transmits it. For fans of cinematic "jumping" of the image, this might be good, but the rest of us simply have to get used to the lack of any motion enhancement.

In terms of motion handling, the S90H is simply excellent. This year's panel offers a boosted refresh rate of up to 165 Hz, though in practice the benefit will mainly be for gamers connecting a high-end PC. For films, 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, however, the OLED panel's lightning-fast response time does its job, so motion is clean and the ghosting or smearing familiar from LCD screens simply does not occur here.

When it comes to gaming on the Blaupunkt, we weren't expecting miracles, and indeed – the list of features is not very long. However, there are two interesting points worth mentioning, as they might be significant for some of you at this price. The first plus is that the TV quickly 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 each time to prevent input lag from ruining the fun. The second point is a genuine surprise that caught us off guard. Although it has a 60 Hz panel, the Blaupunkt can display images at 120 Hz at Full HD resolution. Sure, you lose the details of 4K, 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 inexpensive device. Besides these two points, you won't find anything more here. There are no advanced smoothness enhancement systems for gamers or extensive gaming menu bars. This is a simple screen for occasional gaming.

Players should feel at home with the S90H, because Samsung has left few reasons to complain in that respect. The TV has four HDMI 2.1 ports, each of which supports 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 mode. In last year’s models it could cause problems when used with a console, but on the S90H it now works as it should. What really stands out against the competition is the Game Motion Plus feature. It’s a special motion smoothing mode for games that works best with titles running at 30 or 60 fps. Motion becomes noticeably smoother, while 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 large 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 a much more useful feature.
