TCL C7K / QM7K 50" vs SONY BRAVIA 3 II (XR35M2)

TCL C7K is one of the brightest MiniLED televisions in its price range. Under the best test conditions, the screen was able to achieve over 1200 nits, resulting in impressive, and at times blindingly bright scenes. And most importantly – this is not just a theoretical measurement. In practice, the brightest parts of movies can shine with true cinematic grandeur. Home HDR cinema fans should be truly pleased.

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

However, things get a bit worse when more challenging scenarios appear on the screen, which have been described in terms of contrast – meaning images full of details, with small bright elements against a dark background. In such cases, the C7K often chooses to retain black at the expense of brightness. An example? Scenes from the movies Sicario 2 or Life of Pi, where small light sources (like a distant lantern) can be 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 texture. Nevertheless, it is worth being aware that the visibility of small details in bright areas is not the strongest suit of this model. It is simply a technological limitation that still exists – even with over 300 zones.

Bravia 3 II is certainly not a TV that tries to impress with brightness. In our measurements it reached about 450 nits, so it's far from the strongest designs on the market. That said, HDR here is not just a paper feature. Compared with regular SDR material, the brightest parts of the image can already punch through, and reflections, highlights, or stronger exposures have a bit more energy and stand out better from the rest of the scene. You can see this best in simpler shots where many bright elements appear on screen. Then the Bravia 3 II can give a hint of a higher-dynamic-range picture. The problem only starts with more demanding content, where much greater brightness headroom is needed. There the TV quickly shows its limits and instead of strong, striking HDR we get only a correctly rendered picture.

Colors

Bravia 3 II uses a QLED-type panel, although technically it does not use a traditional quantum-dot layer. Instead Sony applied a PFS phosphor-based solution that serves a very similar role: it allows for more saturated reds and greens and thus lets the TV display a much wider color gamut. Measurements showed about 94% coverage of the DCI-P3 gamut and about 74.4% of the very wide BT.2020. Those are good results for this class of hardware, meaning the Bravia 3 II has no problem showing adequately saturated colors in HDR content. Colors don't look washed out, and the more intense shades can look really attractive.

A new feature in TCL televisions for 2025 is the long-awaited Filmmaker mode, which until now could be found in most competitive brands. This is great news because this mode is considered the truest to the original vision of the creators and is often recommended by enthusiasts of good image quality. Unfortunately – as is often the case – the mere presence of this feature does not guarantee perfection. The Filmmaker mode in the TCL C7K is not free of flaws. One could point out the incorrect white balance, particularly the slight dominance of blue, which caused cool, somewhat grayish skin tones. But that was not the biggest problem. The main complaint was excessive brightness exposure, which is clearly visible on the gamma and EOTF graphs. The image was simply too bright, at times even blown out, which affected not only the plasticity of the scenes but also the overall viewing experience. Some details simply got lost, and the whole image looked as if someone had overdone it with the brightness slider. As always – we decided to see what could be squeezed out of it after calibration. And this is where things got really interesting...

In Professional mode the Bravia 3 II, straight out of the box, delivers a fairly good level of color reproduction. In SDR the most noticeable issue is a slightly low gamma, which makes the midtone areas a bit brighter. White balance is not perfect either; as brightness increases there is a slight lack of blue and red, so whites can sometimes take on a slightly warmer, mildly greenish tint. However, these are not errors that immediately stand out while watching a movie. Average error values hover around 3, so the factory preset can be considered quite good. The situation is similar in HDR. Here again there is a slight deficiency in the blue component, so the image is a touch warmer than the reference, but the difference is not large enough to be significantly distracting during normal viewing.

After calibration, the TCL C7K showed itself in a really good light, especially when it comes to SDR content. We managed to fine-tune the white balance, color gamut, and brightness characteristics so precisely that color errors on the ColorChecker palette dropped below a value of 2. For the uninitiated – this is an almost perfect result, meaning that the image is very close to what the creators intended. Unfortunately, it was less impressive with 4K HDR content. Although we managed to slightly calm the white balance and correct its earlier errors, it is still evident that the TV has certain "MiniLED traits," especially in managing brightness. When we checked how the C7K performed with the EOTF curve on real movie scenes rather than just synthetic test patterns, it turned out that the screen still has 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 shortcomings in 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 color tuning, natural skin tones, and pleasant brightness make movie sessions and everyday content viewing more than satisfactory.

After calibration you can get a lot out of SDR content. The white balance was set almost perfectly, gamma practically matches the reference value, and average color errors fell from around 3 to about 1. That's a level at which differences from the reference image are, in practice, very hard to detect. The Bravia 3 II therefore shows that despite its position in Sony's lineup it has quite a lot of potential for precise picture tuning. Improvements are also visible in HDR, although here you can no longer work around all of the TV's limitations. After equalizing the colors it's easier to notice that the EOTF curve in film material runs slightly below the reference value in places, meaning the Bravia 3 II slightly darkens part of the image. That's not ideal from a reference standpoint, but in this particular TV it also has an advantage. With no local dimming and average black levels, this behavior slightly reduces the visibility of the backlight in darker scenes and helps maintain a greater sense of contrast. So you could say Sony partially masks the limits of the panel that way, rather than trying at all costs to stick to the reference luminance.

The TCL C7K features a function that, according to the manufacturer, is supposed to smooth out unwanted color 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. What's worse – the function can remove elements from the image that should remain. Fortunately, film grain remains untouched, so at least it doesn't smooth everything indiscriminately, but still – it's better to just turn this option off.

As for scaling lower-resolution content, it's already better. SD and HD materials look quite decent, though sometimes we had the impression that the image loses sharpness and becomes too soft – as if something took away its clarity. Fortunately, at very low sources (e.g., 576p), there was no overscan effect, meaning the image was not artificially cropped – everything fit on the screen as it should.

The Bravia 3 II is Sony’s first TV to use the new MediaTek Pentonic 800 chipset, and you can see a few changes in image processing. Starting with the basics: upscaling is solid. The TV can sensibly upscale lower-resolution material and doesn’t have a strong tendency to overemphasize jagged edges or other source imperfections. With regular broadcast TV or lower-quality streaming the picture remains quite pleasing. We have more reservations about the digital image processing. In this model Sony replaced the well-known "Smooth Gradation" feature with a new setting called "Digital Noise Reduction." Its role is essentially the same: to smooth unpleasant tonal transitions and artifacts caused by heavy compression. Unfortunately, this feature performs noticeably worse than before. At the "Large" setting — the only one that noticeably affected the picture — the TV can smooth away too many image elements at once, causing film grain to disappear and surface textures or even character skin to start looking unnatural. Worse, the effect is not very consistent. When a scene contains more motion the function’s effect weakens significantly and at times it looks as if the TV stops intervening in the image altogether. For everyday viewing we therefore don’t recommend using it at a high level. It can help on a static shot, but the price is often too much loss of detail.

TCL C7K handles motion smoothness really very well. The matrix used in it offers a refresh rate of 144 Hz, which already suggests that this TV is something more than just an ordinary "60 Hz" panel. Moreover – 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 about gamers and PC cooperation. Returning to everyday use – both sports and movies look very good here. Thanks to the fast panel and well-functioning motion smoother, the C7K is perfect for watching matches, but also for movie screenings. In the menu, we will find two sliders – blur reduction and flicker reduction – which allow us to adjust the motion smoothness effect to our own preferences. At lower settings, we get a more cinematic effect, with slight frame motion. At higher settings – the image becomes more theatrical, smooth to the point of exaggeration. Everyone can set it to their liking.

Motion handling is definitely one of the Bravia 3 II's strongest points. The TV uses a 120 Hz VA panel, a solution that by nature, despite the high refresh rate, doesn't always cope well with motion blur. Here Sony has managed to get that problem very well under control. Fast-moving objects remain sharp, and the characteristic trails and blurring are reduced to a very low level, if not to zero. It's one of the least smearing LCD TVs we've had the chance to test. Interestingly, in this respect the Bravia 3 II can even outperform the much more expensive flagship True RGB series: the Bravia 9 II.

TCL C7K is a TV that looks like the dream equipment for gamers on paper – and most importantly, it also performs well in practice. First, the good news: we have two HDMI 2.1 ports with full bandwidth, so we can easily connect both a console and a computer, taking full advantage of their capabilities. The panel itself supports 144 Hz refresh rate, which provides a significant advantage in dynamic games. Additionally, it comes with a full package of gaming features: VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), and Dolby Vision support in games. There is also an HGiG mode, which 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 count, VRR status, and even HDR parameters.

Sony Bravia 3 II is a very good TV for gamers, although not everything has been handled the way we'd like. The biggest change concerns the connections. For the first time in a Sony TV we get four full HDMI 2.1 ports with 48 Gb/s bandwidth, thanks to the new MediaTek Pentonic 800 chipset. That removes one of the long-standing issues that has plagued the manufacturer's TVs. You can connect several devices at once and use each input's full capabilities, including VRR and ALLM. There's also a simple Game Bar that lets you check key signal parameters and change a few useful settings, such as black level, when you want to improve visibility in darker parts of a game.

There are, however, two limitations worth knowing. The first is the lack of support for 1440p at 120 Hz. This won't be a problem for everyone, but people using that resolution on a console or PC, for example to get higher frame rates in certain games, will have to choose 1080p. We have more reservations about HGiG support. Sony does not allow disabling tone mapping on the Bravia 3 II, so the TV continuously processes HDR content even when you would prefer to leave that task to the console. You can most easily notice this during HDR setup. The checkerboard pattern does not disappear at the point corresponding to the TV's actual capabilities. That doesn't mean HDR in games will look bad. You just need to approach the setup a bit differently and, instead of relying on the pattern, manually set the peak brightness to about 450 nits. The issue can be worked around, but you should know about it before you start configuring your console.
