Blaupunkt UGC5500S vs TCL C8L / QM8L

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.

When it comes to HDR, the TCL C8L turns out to be a hellishly bright television – and I mean that literally. On a synthetic test pattern of 5%, our measuring equipment indicated a result exceeding 4500 nits. That's an almost cosmic result, considering that reference director's monitors, which we often refer to in our materials, usually operate around 4000 nits. Does this mean the C8L breaks barriers and climbs to the technological peak of Mini-LED? Not quite. Dry synthetic tests are one thing, and real film images are another. In real, varied scenes, the C8L hits around 1600 nits at its peak. That's still a very good result, ensuring a very high level of HDR dynamics, but it's clearly lower than what the manufacturer boasts in the specifications. The trouble begins with very small bursts of light – then the brightness can drastically drop to around 600 nits. The algorithm does everything it can to maintain deep blacks and minimise halo effect, but it does so at the cost of HDR impact. This is ideal evidence that laboratory test patterns rarely correlate with what we ultimately see on the screen.

Huge applause is due for colour reproduction, all thanks to the new generation of SQD (Super Quantum Dot) quantum dots. The coverage of the DCI-P3 palette reaches 97%, but the jaw-dropping measurements come from the notoriously demanding BT.2020 space. The C8L achieves an impressive 90% in this area, placing it alongside today’s top screens that feature RGB backlighting. Importantly, unlike some screens with Micro/Mini RGB backlighting, this effect is stable regardless of the scene being displayed. Of course, it’s important to remember that content mastered for such a wide gamut in films or series is still a rarity. However, the very fact that the panel has such a "reserve of colours" deserves huge admiration.

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.

We tested the TCL C8L in the best factory mode available in the TV's menu for picture fidelity. I’m of course talking about Filmmaker Mode, which was introduced into this brand’s software relatively recently (a year ago in the K series). Thanks to it, the average user can get pretty good colour reproduction straight out of the box, although it’s certainly not perfectly tuned. Looking at the factory white balance of our unit, in both SDR and HDR content, there was a clear lack of the red component, which made the picture noticeably cooler and slightly shifted towards bluish‑green hues. The issue of brightness management is also ambiguous, as we mentioned earlier. While in SDR content the linearity of the gamma parameter is really good and consistently holds the reference value of 2.4, things are much worse in HDR. Tracking the EOTF curve clearly shows the TV’s brightness is considerably boosted across the range, which can make the final image overly bright and inconsistent with the creators’ intent, and that is in a mode that by definition should avoid this. Of course, like every unit in our lab, this one was also subjected to professional calibration, and you can find the results below.

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.

As you can see, the results of a professional calibration of the TCL C8L are genuinely promising, thanks to the extensive adjustment tools the manufacturer made available in the menu. Most importantly, we were able to fully correct the white balance, eliminating a lack of red so the image finally stopped drifting into unwanted, cool tones. After this step, errors in the ColorChecker test fell to near-reference values, regularly sitting below a Delta E threshold of 2, which is under the level noticeable to the human eye.

Since the test patterns look so perfect, you might ask: why then the lower final score in this category? The answer lies in the brightness management discussed earlier. Although the menu includes sliders that let you precisely straighten the EOTF curve on synthetic signals, when confronted with real film material (I recommend turning the EOTF filter on when watching films), it becomes clear that the TV in most scenarios still responds to HDR metadata in its own way. As a result, the image can be a touch too bright and not in line with the creators' intent, and it was precisely for this lack of repeatability with real-world films that we had to dock the C8L a few points.

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.

This year the C8 series and the higher-end models have probably received the biggest and most eagerly awaited upgrade in TCL's history, and it's to do with digital image processing. The C8L is the entry-level model in the manufacturer's line-up to be fitted with the latest flagship MediaTek Pentonic 800 chipset (shown in the menu as MT9655). It is thanks to its processing power that the feature called "Gradual Smoothing" finally works the way it should. The algorithm effectively removes unwanted posterization (ugly tonal transitions / colour banding) from the picture, doing so intelligently enough that it does not degrade the sharpness of other details.

The processor also handles upscaling lower-resolution content to 4K very well. Although judging this element can be purely academic, because the differences between today's TVs in this class are very subtle. The most important point is that TCL finally has nothing to be ashamed of compared with the competition.

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.

The TCL C8L is equipped with a fast panel with a native 144 Hz refresh rate. That spec will be most appreciated by demanding PC gamers, while most users, relying on consoles or TV broadcasts, will use a steady 120 Hz. And it is at 120 Hz that the motion-processing algorithms take care of image processing for films, series and sports. In the TV's menu you'll find a "Motion Clarity" option that lets you customise the motion smoothing to your preferences. The algorithms handle both cinematic productions at 24 or 30 frames per second and fast-paced sports broadcasts at 50 or 60 frames per second, maintaining the right level of smoothness.

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.

For gamers – especially for owners of powerful PCs and multiple consoles simultaneously – the TCL C8L is a true beast. This is the first model in this manufacturer's lineup that is equipped with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This is directly due to the use of the new Pentonic 800 processor, which we've mentioned before. Additionally, the TV seamlessly supports practically every gaming feature. It has an automatic game mode (ALLM) that reduces latency to minimal levels, as well as full variable refresh rate (VRR) operating in an impressive range of up to 288 Hz. It also supports standards such as G-Sync and FreeSync from Nvidia and AMD. When it comes to image display standards, there are no compromises either: the C8L offers complete support for HDR formats in gaming, including gaming Dolby Vision and the HGiG profile. We can conveniently manage all these features from a very readable gamer bar (Game Bar), which we can customise according to our own preferences. From a purely gaming perspective, the C8L really has no flaws – well, maybe apart from the previously mentioned slight ghosting. But other than that? It’s a no-nonsense machine for gamers.
