Samsung S90D / S94D 48" (WRGB OLED) vs Blaupunkt UGC5500S

In the tested film scenes, the television Samsung OLED 48 S90D achieves impressive brightness results, surpassing 800 nits in the first four shots, which can be considered a very good result. In the case of the final shot, where a fullscreen flash of sunlight is visible, the brightness drops to around 400 nits, but still remains at an acceptable level. However, it's worth noting that this model in larger sizes offers higher values, exceeding the "barrier" of 1000 nits. Additionally, speaking of the DCI-P3 colour space coverage at 97% is an excellent result, which guarantees extremely rich and realistic colour reproduction, further enhancing image quality. However, once again it should be remembered that the panel in the 65' variant equipped with a QD-OLED panel will be even better in this aspect. For those hesitating in choosing the size of the S90D model, it is worth mentioning that the larger versions of this television offer better HDR effects, and consequently, higher scores in our tests.

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.

The S90D Samsung television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more demanding users. This mode can seem overly warm, and users switching from Standard mode may experience a slight shock. It's worth noting that this state of affairs is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue, causing colours to become warmer than they should be. In practice, this means that some shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma graph indicates slight fluctuations, causing the image to be minimally darker, especially in shadows. This may affect less distinct details in darker scenes. Conversely, in 4K HDR materials, the EOTF curve is situated above the recommended line, leading to some parts of the image being displayed too brightly, which can cause clipping in the brightest areas. Overall, the Samsung S90D presents a solid image right out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

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.

After calibration, the television Samsung OLED 48 S90D in film mode looks even better than one could have presumed. The white balance, for both HD and 4K HDR content, has been improved to nearly perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the quality of the image. The colours are more balanced, which translates to a natural representation of details, particularly in scenes requiring a precise colour palette. It is worth adding that this model in the 48' size is equipped with a WOLED panel that has a different characteristic compared to larger sizes and has a smaller coverage of a wide colour gamut, not offering such rich colours as, for example, the 65-inch version, which is fitted with a QD-OLED panel.

The contrast has also undergone significant improvement. The gamma graph after calibration is much closer to the expected line, providing a better balance between the bright and dark parts of the image. The EOTF curve, which before calibration showed issues with overexposed scenes, now displays better results. This effect allows for greater detail preservation in the bright parts of the image, especially in HDR material.

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.

The Samsung OLED 48 S90D television performs very well in smoothing tonal transitions. Thanks to the applied technology, the transitions between colours are more fluid and natural. There is also the option to use the noise reduction function, which further smooths tonal transitions, which can be useful in certain situations. However, it is worth remembering that enabling noise reduction can also lead to the smoothing of desired film grain, which in turn can reduce the cinematic atmosphere of the image. For this reason, caution is advised when using this function, as it is better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint and excels at scaling images from lower resolutions. The S90D OLED 48 Samsung television effectively processes lower resolutions, as seen in the visible image. The outline of the model is clear and correct, looking natural and detailed as a result. Moreover, the branches of trees are well replicated, showing no strong jaggedness that could detract from the quality of the image. Thanks to effective scaling, even lower resolution materials look attractive on the screen, satisfying users who prefer a variety of content sources such as regular aerial/cable television.

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.

The S90D television is equipped with a 120 Hz panel, with the possibility of "overclocking" to 144 Hz with the appropriate PC configuration, ensuring exceptional motion fluidity. For years, Samsung has offered a variety of image sharpness settings on a ten-point scale, allowing users to customise the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there is no sign of any blurring. The pixel response is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The image is incredibly sharp and detailed, even during fast action, making the S90D OLED 48 Samsung television an ideal choice for gamers and sports enthusiasts.

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.

The Samsung OLED 48 S90D television is excellently tailored to the needs of gamers, offering four HDMI 2.1 ports that support features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HGIG (HDR Gaming Interest Group). With these technologies, gamers can enjoy smoother gameplay and faster screen responsiveness, significantly enhancing comfort during long gaming sessions. Additionally, the Game Bar feature allows for easy adjustments of settings such as screen ratios, which can be particularly useful in various types of games. For PC users, the television offers an impressive refresh rate of 144Hz, and Nvidia and AMD graphics cards support G-Sync and FreeSync, further improving image fluidity. Although the lack of Dolby Vision support may be a downside, it is worth noting that this technology is not as widely used in games as it is in films. Nevertheless, the S90D still offers excellent features for gamers, making it an outstanding choice for those seeking high-quality visuals and advanced gaming technologies.

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.
