TCL C7K / QM7K vs Sony Bravia 3 50' (VA)

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.

Interestingly, in the 50-inch version, the Bravia 3 performs slightly better in terms of brightness than its larger variants. In measurements, it achieved around 370 nits, which still aren’t values that can compete with top-tier TVs, but are sufficient to speak of a semblance of HDR effect. For some users, this level will be acceptable; others will consider it typical for SDR content, where striking highlights or strong contrasts are not expected. So it must be clearly stated that the Bravia 3 is not a TV for those who want to squeeze maximum quality from the most challenging film materials.

However, this doesn’t mean that everything is average. Sony has equipped this model with an additional PFS filter, which works similarly to the solutions used in QLED TVs. As a result, the coverage of the DCI-P3 colour gamut has increased to over 91 percent. In everyday use, this means livelier, more saturated colours and a more pleasant image quality. Even if it lacks strong lighting effects, movies and series can look significantly more appealing than in its predecessor, the X75WL.

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…

Sony Bravia 3 was primarily tested in movie mode, which immediately turned out to be the best choice among the factory settings. It's not a perfect picture, but compared to the eco mode that the TV suggests right out of the box, the difference is clear and positive. In movie mode, one can notice a certain issue: the image appears too warm, which stems from a lack of blue in the white balance. Nevertheless, in SDR content, the final effect can still be considered quite decent and satisfactory for everyday viewing. Much more serious errors emerge in HDR materials. The Color Checker analysis showed significant deviations, and poor brightness management combined with limited colour gamut coverage further exposes the shortcomings of the picture in this mode. All of this makes HDR on the Bravia 3 seem unconvincing and can spoil the impression left by the quite decent SDR content settings. Fortunately, this is not a hopeless situation. Various errors can be somewhat mitigated, and some can even be completely corrected through professional calibration. That's why we decided to check how the TV would perform after such adjustments.

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.

The calibration allowed us to extract significantly more from the ChooseTV 3 than we could have expected at the beginning. Firstly, we managed to correct the deficiency of blue, which previously caused a noticeable warming of the image. After a slight adjustment in the white balance, most of the errors in the Color Checker measurements for SDR content practically disappeared. The shades of white gained a natural quality, and brightness management in gamma stabilised to an almost ideal level, not exceeding the threshold of human eye perception. Therefore, it can be confidently said that in SDR content, after a few tweaks in the settings, ChooseTV 3 performs really remarkably. Much worse, although still decidedly better than before calibration, are HDR contents. The white balance was managed to be sorted out, however, the limitations of the IPS panel are insurmountable. The lack of local dimming means that even the smallest elements can be overexposed, which is immediately noticeable. Colour-wise, the effect has also improved, although it is far from perfect – many errors still exceed the threshold of four, and even five delta E units, which means they remain visible to the human eye. It was already clear earlier that ChooseTV 3 is not a television designed to impress with HDR quality. Nevertheless, it is pleasing that in SDR content, after calibration, the image can look really great, and in this category, the television has positively surprised us.

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.

Bravia 3 brings more to the Sony TV family than just a shared name. It stands out primarily with its ability to enhance the quality of weaker materials thanks to the processor used. Of course, we won't find the advanced XR chip known from more expensive models here, but even so, it's fair to say that the image in lower resolutions looked surprisingly good. Scaling worked effectively, and most parts of the screen were devoid of the typical excessive edge tearing found in budget constructions. The feature that improves the fluidity of tonal transitions is also noteworthy. At the high setting, it performs quite well, effectively masking gradient imperfections without a significant loss of detail. It does occasionally happen that the algorithm smoothingly blurs elements that should remain sharp – for example, faces – however, in the overall assessment, the effect is beneficial. The best results were achieved precisely at the highest setting, and this option could be recommended to those watching lower quality content.

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.

The fluidity of motion has never been a strong point of televisions equipped with 60 Hz panels, and the Bravia 3 is no exception. Nevertheless, Sony has added something that might appeal to those who are more sensitive to the way images are displayed. This refers to the proprietary motion smoother, Motion Flow, which offers users a lot of adjustment options. With it, you can make the picture smoother, almost theatrical, or stick to a more cinematic style with the characteristic judder, which many people simply associate with a filmic vibe. These functions work for content with lower frame rates, such as movies and series recorded at 24 or 30 frames per second, which is the type of material we encounter on a daily basis. It is precisely in this area that the motion smoother proves to be one of the most important features for everyday use of the television, and here the Bravia 3 performs really well.

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.

Bravia 3 isn't gear for eSports enthusiasts or fans of late-night marathons with a controller in hand. The lack of 120 Hz refresh rate and HDMI 2.1 ports closes the topic before it even has a chance to develop. This is a TV for the casual gamer who, after work, fires up FIFA or racing games, not for someone who measures every frame in a spreadsheet. Nonetheless, Sony has added a few nice extras to ensure it’s not too bare. ALLM works as it should, automatically switching the TV to game mode (low latency). We even find a simple Game Bar here, which is clear and straightforward. However, the biggest curiosity is the PlayStation Portal app. Thanks to it, you can launch games from your PS5 wirelessly and see them on the TV screen straight away. Sounds great, but it only takes a few minutes to feel significant delays. In our opinion, it’s more of a showcase of capabilities than something that can be used on a daily basis. If someone really wants to play, it’s better to plug the console in with an HDMI cable and forget about wireless issues.
