Compare: TCL C7K / QM7K vs Blaupunkt UGC5500S

There are TVs that come for testing, and you immediately think: "oh, just another average one, probably like many others." And essentially... that's true. The TCL C7K doesn't try to dethrone OLEDs, nor does it scream "revolution!" from the box. And yet, after a few days of testing, it's hard not to think: "wow, this is really good gear." And that's exactly what the C7K is. The biggest advantage of the C7K is the decent picture at a reasonable price – MiniLED and quantum dots do their job here. The colours are vibrant, the brightness is satisfactory, the contrast impresses, and with the right settings, you can truly enjoy viewing in the best quality. The second strong point is motion smoothness – both in sports and gaming. Support for HDMI 2.1, variable refresh rate, 144 Hz, and a whole heap of other features makes gaming on this TV a pure pleasure. On top of that, there's Google TV, which – despite some minor shortcomings – offers access to almost an endless library of apps. Voice control, quick access to YouTube, Netflix, AirPlay support – it has everything you need for daily use. Are there downsides? Of course. The Google TV system can have moments of "hesitation," and MiniLED – like any MiniLED – can stumble on very challenging movie scenes. But these are details. After all, the C7K is a mid-range model – and in this class, it performs remarkably well. So if you’re looking for a reasonably priced, modern TV with Google TV that looks good, works well, and sounds pretty decent without breaking the bank – the TCL C7K definitely deserves your attention.

Blaupunkt UGC5500S is a textbook example of a very cheap television that has primarily two major advantages: the Google TV system and an extremely low price. It is these two elements that make it an attractive option for many people. During testing, we also found it has another great use, which is working with a computer. Thanks to exemplary font readability and good viewing angles of the IPS panel, Blaupunkt surprisingly performs well as a budget monitor. However, one must be aware that this device is typically budget-oriented, and that savings are reflected in the image quality. The panel is simply dark, making it difficult to perform well in tougher lighting conditions, not to mention creating any real HDR effect. Additionally, despite the good viewing angles, the black levels on this model leave much to be desired – in the evenings, it will tend to appear dark grey, which is a typical characteristic of the IPS technology used here. From a price perspective, this is a device that aims to compete in the market not on image quality, but rather on the amount on the receipt. Blaupunkt UGC5500S is perfectly suited as a secondary television in the home, equipment for the holiday house, or for a less important room, where the image just needs to be there, and we want to enjoy all the benefits and applications that Google TV offers.

The 50-inch TCL C7K we tested surprised us right from the start – it's the smallest model in the series, yet it's equipped with a VA panel with MiniLED backlighting and – get this – as many as 336 dimming zones. By comparison, many far larger TVs from higher tiers would be happy to boast such a number. Here we have it in a 50-inch version. Sounds promising, right? So how does this translate into real viewing experiences? In the overwhelming majority of tested scenes – very well. The contrast was high enough that in measurements it reached even six-figure values, which in practice means very deep blacks and well-separated highlights. In scenes from films like The Revenant or Oblivion, the effect was impressive, matching the best LCD screens in this class.

Not everything, however, went perfectly. Despite the impressive number of zones, managing them wasn't always exemplary. In more complex scenes, where small light sources or a high level of detail appear, the TV had issues with the so-called halo effect (a glowing aura around bright objects) or overly aggressive dimming of the image. In such situations, contrast could either collapse due to overexposure of some zones or, conversely – details in bright areas vanished because the zones were suppressing light too much. Nevertheless, it's worth emphasising that in the vast majority of scenes the contrast was more than satisfactory. And considering the size of the TV and the price, the final effect will satisfy not only average users.

To put it bluntly: when it comes to black levels, it's just very poor. Our measurements on test patterns only confirmed what we could see with the naked eye – a result around 1000:1 is, these days, even in this price range, a disappointing outcome. In movie conditions, that "black" simply doesn't exist. To avoid being all talk, we fired up one of our favourite test scenes – the helicopter flight in "Sicario 2" (you can actually see it in the video we've linked below). Instead of inky, deep night, we got an image that is... navy blue. Everything on the screen that should be dark and mysterious actually glows a dark blue. This is the price we pay for using an IPS panel. On one hand, we get quite decent viewing angles, so if you're watching TV with the whole family from different angles, the picture doesn't lose much in saturation. On the other hand, if you're planning evening screenings with the lights off, this lack of contrast is going to sting your eyes from the very first minute.

TCL C7K is one of the brightest MiniLED TVs in its price class. Under optimal testing conditions, the screen can achieve over 1200 nits, resulting in impressive, at times dazzlingly bright scenes. And most importantly – this isn’t just a theory from measurements. In practice, even the brightest moments in movies can shine with true cinematic grandeur. Home HDR cinema fans should be really pleased.

The impression is fantastic, especially in scenes with large areas of brightness – a white sky, explosions, sun reflections, or magical sunsets can surprise with an intensity of light that rarely appears in this price range.

However, things get a bit worse when more challenging scenarios appear on the screen, previously described in terms of contrast – that is, images full of details, with small bright elements on a dark background. In such cases, the C7K often opts to preserve black at the expense of brightness. An example? Scenes from movies like Sicario 2 or Life of Pi, where small light sources (like a distant lantern) may become less visible, and details in the lights are simply dimmed or blend into the background.

For many viewers, this may be an acceptable compromise – as we achieve deep blacks and pleasant image depth. Nevertheless, it’s important to recognise that the visibility of small details in bright areas is not this model's strong suit. It’s simply a technological limitation that still exists – even with over 300 zones.

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.

A new feature in TCL televisions for 2025 is the long-awaited Filmmaker mode, which until now has been found in most competing brands. This is great news, as this mode is considered the most faithful to the original vision of the creators and is often recommended by enthusiasts of quality visuals. Unfortunately – as is often the case – the mere presence of it does not guarantee perfection. The Filmmaker mode in the TCL C7K is not without its faults. There are issues with inaccurate white balance, particularly a slight blue tint that resulted in cool, somewhat greyish skin tones. But that wasn’t the biggest problem. The main complaint was excessive brightness exposure, which is clearly visible on gamma and EOTF charts. The image was simply too bright, at times even blown out, which affected not only the texture of scenes but also the overall viewing experience. Some details were just lost, and the entire image looked as if someone had overdone the brightness slider. As always, we decided to see what could be squeezed out of it after calibration. And this is where things started to get really interesting…

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.

After calibration, the TCL C7K showed itself in a really good light, especially when it comes to SDR content. We managed to precisely tune the white balance, colour gamut, and brightness characteristics so that the colour errors on the ColorChecker palette fell below a value of 2. For the uninitiated – this is nearly a perfect result, which means that the image is very close to what the creators intended. Unfortunately, it was a different story with 4K HDR content. While we were able to slightly calm down the white balance and correct its earlier errors, it was still evident that the TV has some "MiniLED traits", particularly in brightness management. When we checked how the C7K handled the EOTF curve on real film scenes, rather than just on synthetic test patterns, it turned out that the screen still had a tendency to slightly brighten the entire image. This affects the overall experience – the black loses some depth, and the image becomes less contrasty than it should be. Despite these minor issues with HDR content, the overall reception of materials – especially in SDR – is really very good. After calibration, the C7K can display an image that can successfully compete with much more expensive models. Good colour tuning, natural skin tones, and pleasant brightness make movie watching and everyday content viewing more than satisfactory.

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.

The TCL C7K performs very well with colour gradation – in most of the scenes tested, tonal transitions were smooth, and colours blended together without visible outlines or the artificial effect of "blotches". In everyday use, it's hard to find any faults – the picture looks natural, without jarring transitions or digital artifacts. Certain limitations only appear in very dark tones – especially in a heavily muted grey palette, where the television may struggle to reproduce the ideal gradation. But that’s absolutely understandable, as even many significantly more expensive models in this range simply can't cope. Fortunately, these situations are rare and don’t really affect the overall perception.

Looking at our test photographs, it’s really hard to pick at anything. Most of the colours in the attached images blend together almost perfectly, creating smooth gradients without noticeable "jaggies". And indeed, in most scenes where we took these shots, it looked surprisingly good. However, the problem arises when we stop analysing still frames and start simply watching the films. In motion, the situation changes dramatically. During dynamic scenes on screen, artefacts begin to pop up, which are a direct result of simply having a poor image processor here. Unfortunately, a static photo can't capture that "tearing" of colours, but you have to take our word for it: what looks clean and smooth in the photo can really stand out and simply irritate during viewing. This is where our rather low rating in this category comes from.

TCL C7K has a feature that, according to the manufacturer, is meant to smooth out undesirable colour transitions – something like a rescue for less successful tonal shifts. It's called "Gradual Smoothing," and... well, it sounds ambitious, but in practice, it works very poorly. Regardless of whether we set it to low or high, the difference is minimal. Worse still – the feature can cut out elements from the image that should remain. Fortunately, film grain remains untouched, so at least it doesn't smooth everything indiscriminately, but even so – it's better to simply turn this option off.

When it comes to upscaling lower resolution content, it's already better. SD and HD materials look quite decent, although at times we had the impression that the image loses sharpness and becomes too soft – as if something took away its clarity. Fortunately, with very low sources (e.g., 576p), there was no overscan effect, meaning the image wasn't artificially cropped – everything fit on the screen as it should.

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.

TCL C7K handles motion fluidity really well. The panel it uses offers a refresh rate of 144 Hz, which suggests that this TV is more than just a standard "60 Hz" panel. Furthermore, if we connect the C7K to a computer and set the resolution to Full HD. But we will write more about this in the paragraph on gamers and PC compatibility. Returning to everyday use – both sports and movies look very good here. Thanks to the fast panel and the well-functioning motion smoother, the C7K is great for watching matches, but also for movie screenings. In the menu, we find two sliders – motion blur reduction and flicker reduction – that allow you to adjust the fluidity effect to your own preferences. At lower settings, we get a more cinematic effect, with slight judder. At higher settings – the image becomes more theatrical, fluid to the point of excess. Whatever your preference – everyone can set it their own way.

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.

TCL C7K is a television that on paper looks like the perfect equipment for gamers – and most importantly, it performs well in practice too. Here's some good news: we have two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, using all their capabilities. The panel itself supports a refresh rate of 144 Hz, which provides a significant advantage in dynamic games. Additionally, it comes with a full set of gaming features: VRR (variable refresh rate), ALLM (automatic low latency mode), and support for Dolby Vision in games. There's also an HGiG mode that allows for HDR effects that align with the creators' intentions. GameBar, which is an information bar for gamers. It operates quickly, looks clear (like a Nintendo console👌), and shows what's most important: the current frame rate, VRR status, and even HDR parameters.

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.

When it comes to delays, the C7K gives no reasons to complain. In games at 120 Hz, the input lag is around 10 ms, which means that the TV responds really quickly. Interestingly, even in Dolby Vision mode, the result is very similar, which isn't always the case. Good job, TCL. At 60 Hz, the lag does increase a bit, but that's completely normal and applies to pretty much every TV with a refresh rate of 120Hz and above. The most important thing is that everything still runs smoothly and there's no feeling that something isn't responding to our actions.

An important point for every gamer is, of course, input lag, which is how quickly the television responds to our movements on the controller. Here, Blaupunkt has something to boast about, although the results are quite specific. At 4K resolution, the lag is only 12 ms. That's an excellent result. With such a lag, gaming is simply phenomenal, and the response is almost instantaneous. However, it's a bit disappointing that the situation changes when switching to 1080p. Here, the input lag increases to around 30 ms. Just to be clear: that's still not a terrible result. For most people, it will be "more than acceptable," and during casual gaming, you probably won't even notice it. Nevertheless, it's a pity that such good parameters couldn't be maintained as we saw with full 4K. Nonetheless, in the overall assessment, as a budget screen for console gaming, Blaupunkt really performs admirably in this regard.

If we plan to connect the C7K to a computer – especially for gaming – there's definitely a lot to play with. We have 4K at 144 Hz, which already sounds great, but if we drop the resolution, the TV can even display 280 Hz. In e-sports, where every split second counts, this really makes a difference. On top of that, it supports G-Sync and FreeSync, so no matter what graphics card we have – the image will be smooth, with no stuttering or tearing.

But if we plan to put the C7K on a desk and use it like a monitor, it's a bit less "rosy." Sure, it supports chroma 4:4:4, so fonts should be sharp, but with very dark letters, you can notice slight blurriness and edge dimming. It's not something that immediately stands out during gaming or watching, but when working with text – it can be distracting. In everyday use – relatively worry-free, but if we plan to have a 50-inch screen a metre from our face, it's worth keeping this in mind.

If you're planning to connect a computer to this television, it's absolutely crucial to find and enable the PC compatibility option in the menu. Once you do this, magic happens – the implementation of Chroma 4:4:4 and font readability jump to an exemplary level. The readability of text is simply excellent here. Of course, our editorial diligence wouldn't let us pass this equipment without taking a look "under the hood." In very specific tests with thin, dark text, we noticed that the horizontal and vertical matrix masks differ slightly in brightness levels. However, we want to reassure you: this phenomenon is so subtle that, during normal use, writing emails or browsing the web, you won't be able to notice it with the naked eye. We maintain our opinion that as a monitor strictly for dynamic gaming on PC, it isn't the ideal choice (as we mentioned in the context of the 60 Hz refresh rate), but if any of you are wondering whether you can comfortably work on such a Blaupunkt – we say: yes, it absolutely can be done.

There's no surprise here – the C7K has classic viewing angles for a VA panel. That is: we sit directly in front – it's excellent. Colours look good, contrast is strong, everything is in place. But just shifting slightly to the side starts to make things worse – the image loses saturation, the blacks turn grey, and the overall impression diminishes a bit. So if we plan to watch together with a few people or have a sofa that takes up half the lounge – it’s worth seating everyone more centrally. You can watch from the side, but don’t expect miracles – it’s simply a characteristic of the VA panel.

Here it's really very good. Whether we were sitting straight on or on the edge of the couch, the colours didn't lose their saturation. This is a big plus if you're planning to watch matches or movies with a larger group – no one will complain that the picture looks worse for them. Although IPS panels are known for their good viewing angles, in this particular model, when viewed from a sharp angle, the picture noticeably loses brightness. Interestingly, the colour saturation still remains in place, but the screen simply becomes darker. It's not something that disqualifies this television, but it's worth knowing.

Luckily, the TCL C7K performs quite well in bright rooms. The applied panel has a satin finish that effectively reduces reflections, so even on sunny days we don't have to worry about reflections from lamps or windows. Importantly, the colours maintain their intensity and don't wash out, as can happen with weaker matte panels. As for brightness, the average for content like YouTube or regular television reaches just below 500 nits. It's not a record result – for example, the MQLED85 (C765) performs better in this regard. However, for everyday viewing during the day, it should work without major issues, as long as we don't plan to place it opposite a south-facing window without curtains.

In terms of daytime performance, Blaupunkt is simply average. It all comes down to the low brightness of the panel, which – as we mentioned, hovers around 250 nits. That’s definitely too low for the screen to comfortably "cut through" the strong light coming into the living room. As a result, in bright sunlight, the image loses its clarity and appears somewhat washed out. However, there is one bright spot in this category: the satin coating of the panel. Thanks to this, we don't have to deal with the mirror effect, which often means instead of watching a movie, we're seeing our own couch reflected. The satin nicely diffuses reflections, which somewhat saves the situation. Nevertheless, we can’t cheat physics: while the coating bravely fights against reflections, the low brightness ultimately capitulates in the face of the sun's rays. If you plan to watch something in the middle of the day in a very bright room, prepare yourself for the necessity of drawing the curtains.

SmartTV: GoogleTV

The biggest strength of the TCL C7K in everyday use is undoubtedly the Google TV system. It is thanks to this that we have access to an almost endless library of applications, including some more niche ones that are often unavailable on other platforms. The built-in Google Assistant understands Polish, so we can easily ask what is on TV, what the weather is like, and even give a few voice commands to control the television. The presence of Chromecast and AirPlay, which work smoothly and make life easier, is also a plus.

Usability Features

However, the traditional functions are a bit lacking. Of course, we have the basics – teletext, EPG, or the ability to connect headphones – but that’s pretty much where it ends. There's a lack of USB recording features or picture-in-picture (PiP) mode, which can still be found among competitors. It's also worth remembering that Google TV in the TCL version sometimes has strangely translated menu sections or minor interface errors. These aren’t issues that hinder daily use, but detail-oriented individuals may notice them.

In terms of Smart TV functionality, the Blaupunkt UGC5500S is a classic example of a device where the system is both its biggest asset and its greatest flaw. On one hand, we have full Google TV, which is a huge plus at this price point. We gain access to a massive library of apps and basically all the functionality we know from brands using this software. Nothing has been cut out forcefully, which is really refreshing in such an inexpensive TV. Unfortunately, it must be honestly admitted that in the case of Blaupunkt, this system operates quite clumsily. This is a typical issue with low-budget TVs running Google TV – the processor barely keeps up with the software. Navigating through the menu isn’t as smooth as we would like, and the remote can react with noticeable delays, giving the impression of being "dull." Of course, once you launch a specific app and start a movie, everything works steadily, but just browsing through the interface requires a bit of patience.

When it comes to classic TV features, Blaupunkt offers nothing extraordinary. It’s a simple device for basic tasks. The remote is a plus, featuring a traditional numeric keypad, which is just convenient for hopping through cable channels. We also have Bluetooth, so you can easily connect wireless headphones or a speaker. The TV also has a physical mini-jack headphone output. At a time when manufacturers are mass-eliminating this connection, the presence of a "jack" is a nod to those with older audio equipment or simply those who prefer classic wired headphones. It’s a small thing, but it’s appreciated.

The built-in file player in the TCL C7K performs really well. It supports most popular audio and video formats, so if we want to quickly plug in something from a USB drive and get it going – there shouldn't be any problem. Of course, as is often the case, you can find some minor shortcomings – not every exotic codec will work (Apple's HEIC), not all subtitles will be perfectly synchronised (txt.). However, the biggest advantage of this television comes to the rescue, which is Google TV. With access to the Google Play Store, we can easily install an alternative player, such as VLC, and then no files will frighten us.

In terms of playing files from USB, Blaupunkt performs quite solidly. We tested several of the most popular formats and basically everything that matters worked without any fuss on the factory player. So you're not forced to immediately download additional software right after pulling the TV out of the box, because the equipment is simply self-sufficient ‘out of the box’. Nevertheless, taking advantage of the charms of Google TV, we still recommend installing some external software, like VLC or Kodi. The factory player is adequate, but it's in those external applications where you'll find the most configuration options, better subtitle support, or just a more convenient interface. Since the system gives you that freedom, it's worth taking advantage of it to get as much as you can out of your multimedia.

To be honest, we didn't expect much from the sound of the 50-inch version of the C7K model. Usually, in such sizes, it's hard to find anything more than thin, flat sound. But here – a pleasant surprise. The sound turned out to be really enjoyable, with good clarity and even a subtly noticeable bass. This is probably linked to TCL's new collaboration with the Bang & Olufsen brand, which is a novelty for 2025. Whether the C7K actually contains original drivers from the Danish premium brand – we can't confirm that. But the end result still deserves a thumbs up. For a TV without a soundbar – it sounds quite nice.

In terms of audio, Blaupunkt performs really well, especially considering it's a typical budget television. You can see, or rather hear, that the brand hasn't forgotten its roots and for such an inexpensive build, the sound is actually superb. Of course, there's a noticeable lack of bass, but overall it's loud, and surprisingly clear. What matters most to us – even at higher volumes, the sound isn't heavily distorted, which is rare and a pleasant surprise at this price point.
