TCL C655 Pro vs Blaupunkt UGC5500S

In the HDR effect quality category, the television TCL 655 PRO demonstrates decent capabilities, achieving a peak brightness of 550 nits. This allows for enjoyment of the HDR effects, which is particularly evident in scenes such as the first from the film Life of Pi or the last frame from The Meg. Nevertheless, the limited number of dimming zones causes some issues. While in bright scenes the television performs better than its lower model, in more demanding scenes, such as the second and fourth scenes from Sicario 2, it struggles. The dimming algorithm aims to achieve deep blacks, but at the cost of brightness – resulting in a drop in brightness of even half during those moments. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles more of an SDR. Regardless, the colour gamut coverage deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

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.

Each of our television tests is conducted in film mode, which usually offers the best colour reproduction. Nonetheless, even this mode is not free from issues, as we noted in the model TCL 655 PRO.

In the case of HD content, the white balance distinctly shifts towards red, and this effect becomes particularly noticeable in a scene from Star Wars, where the white elements of the scenery take on a pink hue. For 4K HDR material, the situation is better, but there is a noticeable tendency to excessively emphasise the colour blue. As a result, the picture may appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristics also leave much to be desired. The Gamma graph indicates serious difficulties with excessive brightening, causing the overall presentation to appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we detailed in the paragraph concerning HDR effects.

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 calibrating the television TCL 655 PRO, a noticeable improvement in white balance is evident, where the tendency for the screen to have an excessive pink hue has been completely eliminated, which was previously visible in the factory mode. The image has taken on more natural tones, especially in white and light elements, positively affecting the overall perception of the picture. Regarding brightness characteristics, the Gamma chart has also improved – the screen is no longer overly bright, which previously made the image appear washed out. However, there are still some issues with the EOTF curve, which are difficult to eliminate due to the design of the television and its limited number of backlight zones. These limitations prevent achieving perfect results in this regard. Nevertheless, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high picture quality and very good colour reproduction.

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 TCL 655 PRO television performs quite well with tonal transitions in lower quality materials. The "Gradual Smoothing" function at a low setting effectively smooths out tonal transitions, but this comes at the expense of losing some important details, such as the texture of objects. One positive aspect is that it does not negatively affect film grain, which helps maintain the natural appearance of the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a more vivid image. However, those who like a softer, subtler look may find this a drawback. Additionally, a downside is the cropping of the image due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - for example, news tickers.

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 TCL C655 PRO television is equipped with a 4K panel with a refresh rate of 60 Hz, making it best suited for watching films. Additionally, the "Flicker Reduction" feature allows users to adjust the smoothness of the image, giving them the choice between a smoother motion and a cinematic, frame-by-frame effect. Moreover, the television performs well with lower resolution materials, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy a smoother picture at the expense of lower resolution.

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 TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all the key technologies that significantly enhance the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in improved responsiveness and minimal signal delay – particularly important in dynamic titles. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and thus guaranteeing smoother gameplay.

Support for Dolby Vision in gaming mode allows for more detailed colour and contrast reproduction in games that support this format, while the Game Bar provides quick access to essential settings such as response time and latency level. Unfortunately, the model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those willing to forgo 4K, support for Full HD and 2K at 120 Hz delivers exceptionally smooth visuals, presenting an attractive alternative for enthusiasts of higher refresh rates.

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.
