Blaupunkt UGC5500S vs TCL C6KS / C69KS / Q6CS

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.

And what about HDR? Here the C6KS performs quite well and – as is becoming the theme of this review – just like in the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect and generally, video materials look good here. However, it's important to keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g. stars) appear on a dark background, the television can quite significantly dim them. The goal is simple: to eliminate blooming and maintain the best possible black. It's a reasonable compromise. Most viewers will definitely appreciate deep, “true black” more than additional microscopic details, the display of which could cause the screen to appear greyed out. Such is the nature of local dimming technology in this price range, and one must be aware of this. It’s also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the QLED technology slogan. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92%.

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.

In contrast to the more expensive C6K model, in the tested C6KS we don't find an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests showed that in practice, in terms of colour reproduction, the lack of this specific label makes virtually no difference. The best available Film/Cinema mode here offers an almost identical picture profile to the aforementioned Filmmaker in the more expensive model. So we get a very similar image, just under a different name. Therefore, if you were wondering whether paying extra for the C6K would give you better colours – the answer is: no, in both cases the base is the same and requires slight adjustments.

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.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, leading to a very good final effect. After calibration, we will no longer see excessive warmth in SDR scenes or overly cool tones in HDR. However, it is worth noting the brightness characteristic. In SDR content, there are hardly any objections – the image looks very good, especially in older films, TV shows, or YouTube materials. Evaluating the television's performance in HDR is much more difficult. Analysis of the EOTF curve suggests correct behaviour, but its practical variant shows certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times it can dim the entire scene. Calibration has therefore brought clear benefits in terms of colour, but certain limitations resulting from local dimming and the way it is controlled by the C69KS cannot be avoided, which we also observed in the C6K test.

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.

The C69KS handles upscaling quite well. The tested 576p content looks surprisingly decent – a considerable amount of detail is preserved, and the algorithm adds a subtle ‘rounding’ effect to sharp edges, making the image appear more cohesive. However, it doesn't perform as well when it comes to smoothing tonal transitions. The television practically cannot improve them, leaving the image in a rather raw state. With older materials, this can be simply exhausting, as the lack of additional processing highlights all imperfections.

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.

C69KS offers a simplified motion enhancement panel in movies, allowing users to adjust the intensity of the effect using a slider. This makes it easy to tailor the smoothness to personal preferences. It also deserves credit for the ability to utilise higher refresh rates – even though the panel operates natively in 4K at 60 Hz, by lowering the resolution to 1440p, modes of 120 and 144 Hz can be enabled, on both consoles and PC. This sounds like great news, however, in practice, the image at these settings trails exceptionally badly. The effect is so pronounced that the overall experience simply appears mediocre and loses its appeal in everyday use.

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.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS is impressive in how well it performs for gaming. You get everything you would expect from a gaming TV: Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), Dolby Vision Gaming mode, and a consistently functioning HGiG. The TV can also operate at 120 or even 144 Hz at lower resolutions, making gameplay on console or PC smoother. Additionally, there's a clear Game Bar that allows you to quickly check key settings while gaming. As a result — despite a few limitations — the C69KS can be a genuinely successful screen for gamers.
