Blaupunkt UGC5500S vs TCL C8L / QM8L

Here, we won't beat around the bush either – if you're looking for a TV strictly for cinematic HDR experiences, you've come to the wrong address. The Blaupunkt UGC5500S unfortunately is 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 screens speaks for itself. It's simply too little to even talk about any real HDR effect. To be honest, everything displayed here in this format can best be considered a slightly "boosted" SDR mode. We expected this because practically every device in this price range fails in this regard, but we feel obligated to warn you. Manufacturers love to boast about HDR compatibility stickers on the boxes, but in reality, this format simply doesn't exist here – it lacks the "fuel" of brightness.

The situation is made all the more difficult for Blaupunkt because we have a panel with a very basic DCI-P3 color gamut coverage of just around 80%. You won't find any advanced coatings that enhance these capabilities (like quantum dots), making scenes that are supposed to burst with richly saturated colors appear simply desaturated on this screen. Therefore, we have a concrete piece of advice for you: do not push the HDR mode on this model. If you have the option in the streaming app settings – just turn it off. Sticking with the classic SDR mode will ensure that the TV won't try to "enhance" something that it can't handle hardware-wise.

In terms of HDR, the TCL C8L turns out to be a hellishly bright television – and I mean literally. On a synthetic chart of 5%, our measuring equipment indicated a result exceeding 4500 nits. This is a result that is downright cosmic, considering that reference director monitors, which we often refer to in our materials, typically operate around 4000 nits. Does this mean that the C8L breaks barriers and climbs to the technological peak of Mini-LED? Not exactly. Dry synthetic tests are one thing, and real movie images are another. In real, varied scenes, the C8L achieves a peak of around 1600 nits. This is still a very good result, ensuring a very high level of HDR dynamics, but also clearly lower than what the manufacturer boasts in the specifications. The trouble starts with very small flashes of light – then brightness can drastically drop to around 600 nits. The algorithm tries at all costs to maintain deep black and minimize halo effect, but it does so at the expense of HDR impact. This is perfect evidence that laboratory charts rarely correspond to what we ultimately see on the screen.

Huge applause is due for color 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 true jaw-dropper is the measurement of the extremely demanding BT.2020 space. The C8L achieves as much as 90% in it, placing it alongside today's top screens that boast RGB backlighting. Importantly, unlike some screens with Micro/Mini RGB backlighting, this effect is stable regardless of the scene displayed. Of course, one must remember that content mastered for such a wide gamut in films or series is still a rarity. However, the mere fact that the panel has such a "color reserve" deserves immense admiration.

We also took a close look at how Blaupunkt handles colors in movie mode, and here the situation is, to put it briefly, twofold. We must clearly separate what we see in the standard SDR format from what happens when HDR is turned on, as these are two completely different worlds. Let’s start with the better side of the coin. If you plan to watch classic television, YouTube, or older movies on this TV, you can count on really well-tuned colors. In our test sample, the white balance in movie mode was exceptionally accurate, which honestly surprised us. Of course, to not make it too rosy, we noticed some flaws. Looking at the gamma charts, we observed that the processor struggles with properly dimming the image in its brightest parts. Additionally, there is quite strong, at times too aggressive, red saturation, which resulted in noticeable errors in reproducing certain shades. Nevertheless, in general terms, 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 form. The excess blue in the white balance is so overwhelming that it literally clashes with the eyes, ruining any realism of the scene. Furthermore, the TV interprets brightness very loosely, which, when analyzing the EOTF curve, clearly showed that for most of the time the colors appear simply washed out and lacking depth. This is, by the way, perfectly visible in the color 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 not properly refined.

We tested the TCL C8L in the best factory picture mode available in this TV’s menu for image fidelity. That, of course, is Filmmaker Mode, which appeared in this brand’s software relatively recently (a year ago in the "K" series). Thanks to it, an average user can get a pretty good color reproduction straight out of the box, although it is certainly not a perfectly tuned mode. Looking at the factory white balance of our unit, both in SDR and HDR material, the red component was clearly lacking, which made the image noticeably cooler and caused a slight shift toward bluish-green tints. The issue of brightness management is also ambiguous, as we mentioned earlier. While for SDR content the gamma linearity is actually correct and holds steadily at the reference value of 2.4, in HDR things look much worse. Tracking the EOTF curve clearly shows the TV has a significantly boosted brightness across the range, which can make the final image overly bright and inconsistent with the creators’ intent, and that in a mode that by definition should avoid that. Of course, like every sample in our lab, this one also underwent professional calibration, and its results are shown below.

It may sound like a joke – pulling out professional measurement equipment for a television costing around a thousand zlotys / 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 calibration? To your surprise, the answer is yes, and absolutely 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 concrete tools that enabled us to make use of our measurement sensors and software. In SDR mode, the effects were noticeable to the naked eye. We successfully eliminated the issue we mentioned earlier – that excessive, almost artificial saturation of reds. We also fixed the problem of incorrect dimming of the brightest parts of the image. After calibration, the standard format picture became much more balanced and simply correct. As for HDR, the situation was again more complicated. Although we managed to "tame" that aggressive blue tint in the white balance, it was evident that we were fighting a bit in vain. Even after changing the settings, the television still tried to intervene in the image in its own way, as if the electronics knew better than we did how the scene should look. Additionally, there's a hardware barrier that no slider can overcome – colors in HDR still remain unsaturated. This simply results from the quality of the panel itself; it physically cannot produce the most vibrant colors. To summarize this point: if any of you ask whether it’s possible to calibrate a television for "a thousand," we respond with full conviction: it is possible.

As you can see, the results of a professional calibration of the TCL C8L are really promising, thanks to the extensive adjustment tools the manufacturer put at our disposal in the menu. Above all, we were able to completely correct the white balance — we eliminated the red deficiency, so the image finally stopped drifting toward unwanted cool tones. After that adjustment, errors in the ColorChecker test fell to near-reference levels, regularly landing below a Delta E of 2, which is below the threshold of human perception.

If the test patterns look this 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 actual movie material (I recommend enabling the EOTF filter when watching movies), you can see that in most scenarios the TV still reacts to HDR metadata its own way. As a result, the picture can be slightly over-brightened and not faithful to the creators' intent, and it was precisely this lack of consistency with real films that cost the C8L a few points.

If you expect that the processor in this model will magically "fix" the poor quality signal from cable TV or old films from YouTube, we must disappoint you. The capabilities of this television end with 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 talk of any intelligent sharpening or adding details. Worse still, Blaupunkt is completely devoid of any functions that reduce unwanted tonal transitions. If the material being viewed has so-called banding (ugly "steps" instead of a smooth transition of colors, e.g., in the sky), this television will display them in all their glory. Additionally, the television tends 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 located 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 higher models received probably the biggest and most anticipated upgrade in TCL’s history, and it specifically concerns digital image processing. The C8L is the lowest-end model in the manufacturer's lineup to be equipped with the latest flagship chip, the MediaTek Pentonic 800 (listed in the menu as MT9655). Thanks to its processing power, the feature called "Gradual Smoothing" finally works as it should. The algorithm effectively eliminates unwanted posterization (ugly tonal transitions/color banding), 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 evaluating this element can be mostly academic, because the differences between today's TVs in this class are very subtle. The most important takeaway is that TCL finally has nothing to be ashamed of compared to 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 during fast action scenes or while watching a game. However, the biggest drawback of this model is that you won't find any digital smoothers in the menu. The manufacturer did not give us any room to maneuver – there's no way to smooth anything out or adjust the image to our preferences. The image is always "raw" and we receive it exactly as the source transmits it. For fans of cinematic "motion jump," this might be fine, but everyone else just has to get used to the absence of any motion support.

The TCL C8L is equipped with a fast panel that has a native 144 Hz refresh rate. That spec will be most appreciated by demanding PC gamers, while most users, who rely on consoles or TV broadcasts, will use a steady 120 Hz. It is at 120 Hz that motion processing algorithms handle image rendering for movies, series, and sports. In the TV’s menu you’ll find a "Motion Clarity" option that lets you adjust the motion smoothing to your preferences. The algorithms handle cinematic material at 24 or 30 frames per second (fps) as well as dynamic sports broadcasts at 50 or 60 fps, maintaining appropriate smoothness.

When it comes to gaming on the Blaupunkt, we didn’t expect miracles and indeed – the list of features is not very long. However, there are two interesting points worth mentioning, as they may be significant for some of you at this price. The first advantage is that the TV quite efficiently detects the connected console. Thanks to the ALLM (Auto Low Latency Mode) feature, the device automatically knows when you start gaming and switches to low latency mode. This is convenient because you don’t have to fiddle with the settings every time to prevent input lag from ruining the fun. The second point is a real curiosity that surprised us. Even though it’s a 60 Hz panel, the Blaupunkt can display images at 120 Hz at Full HD resolution. Sure, we lose 4K details then, but for those playing more dynamic, online shooters where fluidity is more important than resolution, it’s a really nice and unexpected addition in such an inexpensive piece of equipment. Besides these two points, however, you won’t find anything else here. There are no advanced systems for improving fluidity for gamers or extensive gaming menu bars. It’s a simple screen for occasional gaming.

For gamers – especially for those with powerful PCs and several consoles at the same time – the TCL C8L is a true beast. It’s the first model in the manufacturer’s lineup equipped with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This is directly thanks to the new Pentonic 800 processor we wrote about earlier. Additionally, the TV seamlessly supports virtually every gaming feature. It has an automatic game mode (ALLM) that reduces latency to minimal levels and full frame synchronization (VRR) operating in an impressive range of up to 288 Hz. We’re also talking about standards like G-Sync or FreeSync from Nvidia and AMD. When it comes to image display standards, there are also no compromises: the C8L offers complete support for HDR formats in games, including gaming Dolby Vision and the HGiG profile. All of these features can be conveniently managed from a very readable game bar (Game Bar), which we can customize according to our preferences. From a purely gaming perspective, there really isn’t anything to complain about in the C8L – well, maybe aside from the previously mentioned slight ghosting. But other than that? It’s an unflawed machine for gamers.
