TCL C855 vs Blaupunkt UGC5500S

The TCL C855 delivers a highly varied HDR effect. At times, the television truly excels, while at other moments, it appears reminiscent of a low-end model equipped with FALD backlighting. Inconsistency is frequently found with this brand, so it didn’t come as a surprise. The first and last scenes, which feature large light elements, are nothing short of spectacular, boasting brightness levels of 1470 and 1820 nits, respectively. Such brightness can make viewers squint their eyes, allowing them to feel the extraordinary dynamism of the scene. It genuinely immerses the audience, creating a sensation of being inside the movie itself. However, the situation shifts dramatically when small or subtle elements with high luminance appear against a dark background. In these instances, the TCL C855 significantly reduces brightness to levels as low as 240 nits to mitigate halo effects. This reduction is disappointing, as it can make the movie appear as if it was not filmed in HDR. Despite these shortcomings, the HDR effect on the TCL C855 enhances the viewing experience during dynamic scenes, making it feel more engaging and allowing the viewer to feel part of the action. Even with smaller high-luminance elements, the television retains details without excessive dimming. Additionally, the TCL C855 adjusts image brightness according to scenes with rich detail, further enhancing viewing comfort.

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.

The best factory mode for the TCL C855 is the "Film" setting, and all our tests were conducted using this mode. However, like many predefined modes, it has flaws that should be addressed to achieve an image closer to the producer's original vision. In our examination of the colour characteristics for both SDR and HDR materials, issues were found.

Focusing first on SDR content, there is a noticeable dominance of green in the white balance, which leads to an unpleasant greenish tint across the entire image. The gamma chart, crucial for image contrast, shows a significant deviation from the reference line marked at 2.4. Initially, there is a pronounced spike in the measured value, resulting in an over-contrasted image where details can merge into a dark blob. This condition persists for nearly 20% of the chart before it dips below the reference line, causing the image to brighten and resulting in a substantial drop in contrast.

In HDR materials, the factory mode performs somewhat better; the white balance appears more balanced overall, although the green tint resurfaces in the latter half of the spectrum. When we look at the Electro-Optical Transfer Function (EOTF) curve—unlike gamma, which reflects contrast—we identify two main errors: the darkest scenes are too dark, while the brightest ones become overexposed. This discrepancy was evident in our review of the scene from the movie "Pan," further illustrating the TCL C855's HDR performance issues.

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.

TCL, like most manufacturers, offers advanced calibration tools within its televisions. These include both 2-point and 20-point adjustments for grayscale, as well as a comprehensive colour management system. As a result, we achieved impressive results in SDR materials, bringing the image significantly closer to the reference standard. We successfully eliminated both the green tint and the gamma issue, although a slight "kink" at the very beginning of the gamma curve still persists.

In contrast, the situation with HDR materials was less favourable, as the TCL C855 did not allow for precise modelling. We were only able to make minor adjustments to the EOTF curve while significantly enhancing the overall colour accuracy. This limitation suggests that while calibration tools are effective, they may require further refinement for optimal HDR performance.

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.

Once again, we will take a look at the function of smoothing tonal transitions, but this time also image scaling. The latter is particularly important when watching materials of lower quality, such as some television programs or older films. We will focus on the function responsible for tonal transitions. Interestingly, just like in the scenes from the previous test where it performed excellently and smoothed out practically all the inconsistencies, here it had issues. Using the menu responsible for the operation of this function, we found that no setting—even the strongest—was helpful.

Image scaling in TCL C855 is defined as one of the best we have had the opportunity to test so far. The image is sharp, but in a way that could be described as natural to our eye. Even small, fine branches do not have jagged edges, and there is no white halo around figures, a characteristic of weaker scaling systems.

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.

The maximum refresh rate you can set on the TCL C855 is 144 Hz. Naturally, this is only possible after connecting the TCL C855 TV to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we want to watch primarily sports or materials with a lot of motion dynamics. For those who require high image fluidity, the manufacturer has implemented a multi-stage motion smoother. It is divided into two separate sliders which control the sharpness of moving images (Motion Blur Reduction) and flicker (Flicker Reduction). Both sliders can be adjusted from 0 to 10, with each level affecting the degree of fluidity, so everyone can find their sweet spot. We present a setting that allows for slight smoothing without the soap opera effect. The matrix of the TCL C855 features a very good response time. This is particularly important since VA panels often struggle with the so-called ghosting effect, where a black halo can be observed behind a fast-moving object. where a black halo can be observed behind a fast-moving object.

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 C855 TV has fully-featured HDMI 2.1 ports, boasting a full bandwidth of 48 Gb/s. During our testing, we confirmed the seamless operation of all functions included in this connection standard. As highlighted, all checkboxes are illuminated in green, a feature that will undoubtedly be appreciated by gamers, whether on consoles or those using the TV as a computer monitor. Additionally, the TCL C855 supports both AMD FreeSync and NVIDIA's G-Sync, which can be easily activated in the graphics card settings. Those with powerful configurations can feed a 144 Hz signal to the C855, which handles this effortlessly. It is also worth noting the implementation of the HGIG mode, which can be excessively bright due to the shortcomings of the "Game" mode, making proper configuration on the screen challenging. Fortunately, the TV excels with the Dolby Vision format.

TCL, as one of the pioneering manufacturers, has equipped its televisions with a special GameBar, allowing for extensive adjustment of settings "on the fly" without the need to exit the game. This feature includes options like an additional crosshair grid, black level correction, and settings designed for individuals with disabilities. The image showcases the next generation of this solution.

In summary, the TCL C855 TV is an ideal choice for those seeking a screen for all forms of electronic gaming. With comprehensive features supporting such entertainment, it provides an extremely engaging experience. It is also important to emphasise that it maintains very low input lag, regardless of the selected settings, including when using the Dolby Vision HDR format.

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.
