TCL C7K / QM7K vs Sony BRAVIA 7 II

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.

Sony Bravia 7 II handles HDR very well and, above all, is simply a bright television. In the correct viewing mode for watching, Professional, we measured about 2,000 nits of peak brightness, so the panel’s capabilities are truly large. Of course, in Mini-LED sets a test-pattern result is only part of the story, because much still depends on how the TV controls the backlight in real scenes. Here Sony’s algorithms perform really well. Depending on the scene, the brightness we measured in films ranged from about 1,100 to as much as 1,700 nits. That’s a level at which HDR has proper punch and bright highlights can be genuinely impressive. It’s not perfect in every situation. With small bright elements on a very dark background, the Bravia 7 II clearly prioritises maintaining good black levels, so their brightness can fall to around 500 nits. It still looks good, but it’s clear the TV doesn’t always manage this without compromise.

Colours

The second thing that has a huge impact on HDR is, of course, colour. And this is where True RGB was meant to deliver one of the biggest changes. Looking at the panel’s capabilities alone, the Bravia 7 II performs very well. We measured roughly 98% DCI-P3 coverage and 88% BT.2020, so the potential for showing highly saturated colours is substantial. In RGB TVs the matter is a bit more complex. When we repeated the same measurements with a film-like background applied, gamut coverage dropped to about 92% DCI-P3 and 78% BT.2020. Those are still good numbers, especially for an RGB Mini-LED TV, but they show that the final result largely depends on how the algorithms drive the three backlight colours. In most scenes the Bravia 7 II handles this well and colours retain strong saturation. The biggest differences are visible in blue shades, where samples start to deviate more noticeably from the reference values and coverage is weaker than for the other primaries. True RGB therefore offers genuinely greater potential, but, as with brightness, a lot depends on what’s actually happening on screen.

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…

To evaluate the factory colours we chose the Professional mode, because it performs best among the available presets. It's not perfect. In SDR the white balance is slightly biased toward magenta, so some scenes look a little warmer and less neutral than they should. A bigger issue is the gamma, which sits closer to 2.5 than 2.4. As a result the image is a bit too dark in places, especially in the mid-tones. In HDR the situation is better. As brightness increases there's a little too much red, but it isn't something that really jumps out while watching. Overall the Professional mode is a good starting point, though you can get a bit more out of it with calibration.

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.

After calibration the Bravia 7 II can look significantly better. First and foremost, we managed to set the white balance very well in both SDR and HDR. Gamma can also be improved, and after correction it runs very close to the reference value. For most users those changes will have the biggest impact on the picture. There is, however, a limitation with the colours themselves. On the Bravia 7 II Sony does not provide access to a traditional CMS that would let us adjust individual hues separately. Much is left to the algorithms controlling the True RGB backlight. If the TV reproduces a specific colour inaccurately, we are not always able to do anything about it. In our measurements this is most apparent in parts of the reds and blues, where errors can still be quite large. That does not, however, undermine the value of calibration. Correctly setting the white point and gamma strongly affects the whole picture, so even without the ability to precisely correct every colour the difference from the factory settings is noticeable.

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.

Scaling and digital processing are among the strongest points of the Bravia 7 II and one of Sony's biggest advantages over the competition. Sony has for years excelled at digital image processing, and it's clear here too. Above all, the 'Smooth Gradation' function works very well, smoothing weaker tonal transitions in poorer-quality content. The safest setting is low, but we'd comfortably recommend medium as well. The effect is stronger, and the TV still handles fine detail very delicately. Some minor details may be slightly smoothed, but Sony does it much more subtly than many other brands. Upscaling is also very good. Lower-resolution content is nicely upscaled to 4K; the image looks clean and retains a lot of detail. Of course the TV won't magically turn native HD into true 4K, but the Bravia 7 II does very well with what can be pulled from such a source.

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 Bravia 7 II uses a 120 Hz panel, so in terms of motion handling it delivers everything you'd expect from a TV of this class. With sport or games at 120 fps the picture is suitably smooth, and for films Sony provides an advanced motion interpolation system. You can therefore adjust the level of interpolation separately and choose whether to retain a more cinematic motion or achieve noticeably greater smoothness. Motion blur itself is a bit worse. The VA panel used isn't among the fastest, and moving objects can show a slight trailing, especially against darker backgrounds. It's not at a level that will seriously disturb normal viewing, but last year's Bravia 7 was better in this regard and had a noticeably faster panel.

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 7 II has pretty much everything you'd want from a good console TV today. It supports 4K at 120 Hz, VRR from 48 to 120 Hz and ALLM, so when you start a game the TV automatically switches to low-latency mode. HGiG works correctly, so once you configure HDR on the console the TV won't try to brighten the image on its own. Just remember to turn off tone mapping in the TV's menu. Another plus is Dolby Vision in game mode, which will be especially useful for Xbox owners. Sony also includes its own Game Menu, where you can quickly view key signal info, check VRR or change gaming settings without digging through the full TV menu. The only thing missing from the feature list is support for 1440p at 120 Hz. Our biggest complaint is not really about the features but the connectors. The Bravia 7 II has four HDMI ports, but only two of them support full HDMI 2.1 with 48 Gbps bandwidth. One of those is also the eARC port. So if you connect a soundbar or AV receiver via HDMI, in practice you only have one full HDMI 2.1 left for a console or PC. With a single console that's fine, but with a PS5, an Xbox and an audio setup it starts to feel cramped. That's hard to justify from Sony. In cheaper TVs two HDMI 2.1 ports can still be accepted, but in a model of this class, especially in 2026, we'd expect all four ports to be HDMI 2.1.
