Samsung QLED Q70D / Q74D / Q77D vs Blaupunkt UGC5500S

The brightness that the Samsung Q70D can offer is at a fairly average level, although it cannot be said that the HDR effect will be unnoticeable. Any brightness above 400 nits allows for a clear distinction between SDR and HDR materials. As was the case in the paragraph about contrast and black levels, this time we can observe that the first scene, featuring a bright sun and a dark foreground, possesses the lowest luminance among the measured ones. The result, which can be considered very good for this price range and class of display, is the latter. In a scene where we see a large light source filling a significant part of the frame, the brightness of the television is at its highest, reaching nearly 500 nits. It is worth noting the quite low coverage of the wide DCI-P3 colour gamut, which occasionally results in noticeable gaps in the colour palette. Additionally, users can enjoy rich colours and high precision in shade reproduction, making movie screenings a special experience. It is also worth noting that the Q70D Samsung panel performs excellently in eliminating blur during dynamic action scenes, which enhances the viewing comfort of sports broadcasts or games.

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 best factory mode on the Samsung Q70D is "Filmmaker," and it was this mode that we used during all our tests. Before calibration, it had several flaws that effectively prevented it from conveying the director's intentions. In both SDR and HDR materials, the white balance was dominated by red and green. As a result, there was a characteristic yellow tint on the image, causing white to appear yellowed and resulting in skin tones that were noticeably too warm. The lowered gamma in standard colour gamut materials resulted in a significant drop in contrast, which was already not the highest. This caused detail in the blacks to be accentuated but also led to overexposure in brighter scenes. The EOTF curve, in this case, proved to be much better and only brightened those scenes with relatively low luminance. This was perfectly evident in the section where we measured the television's maximum brightness in HDR materials. At that point, the frame from the film "Billy Lynn" was unnaturally bright and lacking in depth.

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.

Fortunately, Samsung provides a wide range of calibration tools in all its televisions, including 2-point and 20-point grey scale adjustment as well as advanced CMS. This allowed us to significantly improve the quality of SDR and HDR content. The vast majority of errors have been corrected, and the image that the Samsung Q70D now generates is definitely closer to the reference. Higher deltaE errors in wide dynamic range content are primarily due to the display's insufficient luminance.

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 function responsible for improving gradation has been named "Noise Reduction" in the menu. As we have confirmed, it is worth enabling, as it has a positive effect on tonal transitions. More importantly, it does not negatively affect the film grain or the fine details, which the competition sometimes "blesses" us with.

The image scaling on Samsung Q70D should be rated as average. The manufacturer does not intend to artificially sharpen the image, but rather to leave it naturally softened.

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.

Samsung Q70D is the first model in the manufacturer's portfolio featuring a 120Hz panel. Consequently, its motion smoothing functions are more advanced than those in lower-tier models. Within the menu, we find three functions responsible for improving smoothness: "Motion Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." We will discuss the third one later. The first function is responsible for sharpness in motion, while the second adjusts the level of smoothing. The smoother in Samsung Q70D performs satisfactorily, and each setting brings noticeable changes. Therefore, those who dislike the characteristic juddering in films or are avid sports viewers will be able to achieve a personalised level of smoothing. In the picture, we present a setting with slight smoothing, without the soap opera effect.

The panel used in Samsung Q70D features a fairly good response time for this type of display. Of course, it won't be as sharp as a proverbial razor, but at this price, it is a recommendable choice for all kinds of sports.

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 tested television is equipped with four HDMI 2.1 ports. Interestingly, all of them have a bandwidth of 40 Gbps; however, during the conducted tests, we did not find any negative effects related to this state of affairs. Moreover, and more importantly, Samsung Q70D supports all functions resulting from the aforementioned standard. This news will surely please all gamers, as it means that whether using a console or a PC, we can count on the highest possible comfort during gameplay. Given the typical absence of HDR Dolby Vision for this manufacturer, it is significant that the HGIG mode has been correctly implemented and there is no issue with setting the calibration checkerboard. We particularly note that Samsung, as the only manufacturer, allows gameplay with the smoothener turned on, without significant degradation. This means that titles running at 30 fps will be perceived like those with native 60 frames per second.

Samsung, as one of the first manufacturers, introduced the Game Bar to its televisions, which it has consistently refined since then. It contains all the necessary information regarding gameplay parameters that we can change "on the fly".

To summarise: Samsung Q70D performs excellently both with a console and a computer. All functions worked perfectly and there were no issues with them. The ability to enable the smoothener without a significant increase in input lag is a true game changer.

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.
