TCL A300W NXTVision vs TCL C7K / QM7K 55"-85"

When it comes to brightness, the TCL A300W is definitely the dimmest TV among all frame-style models, such as Samsung The Frame or Hisense CanvasTV – and unfortunately, you can see that right away. In our measurements, peak luminance reached only around 400 nits, and on test movie screens, this value dropped to 350 nits. That’s definitely too little to feel the real "magic" of bright HDR effects. As a consolation – the TV is equipped with a PFS LED coating (which is something like QLED), which provides very good coverage of a wide colour gamut, both DCI-P3 and BT.2020. In addition, there is full support for all popular HDR formats – HDR10, HDR10+, HLG, and Dolby Vision – which somewhat compensates for the shortcomings in brightness and helps improve the overall experience of materials in this quality.

In terms of brightness, the models ranging from 55 to 85 inches in the C7K series are truly impressive. Under optimal testing conditions, the 65-inch screen exceeded 1200 nits, which in practice means that the brightest scenes can dazzle with almost cinematic brilliance. These are not just dry figures from measurements – during screenings, bright skies, explosions, or reflections of light on water looked incredibly striking, often giving the impression that the television exceeds its price range. This is particularly effective in scenes with large areas of illumination, where the screen fills with intense brightness – for instance, in sun-drenched shots or during dynamic action sequences. Viewers looking for strong HDR will definitely be satisfied.

However, scenes that require precise backlight control – with tiny points of light against a dark background – prove to be more challenging. Here, the C7K, despite having over a thousand zones, can still dim brightness to maintain deep blacks. The effect is that in films like Sicario 2 or LIFE of Pi, some details, such as a distant lighthouse or single reflections, may appear less distinct or blend into the surroundings. This is a compromise inherent in MiniLED technology – it provides excellent image depth and blacks at a level not offered by standard LCDs, but this comes at the cost of limited visibility of the tiniest lights.

TCL A300 offers several picture modes, but without a doubt, the movie mode performs the best. Unfortunately, even though it is the best option available, it is not free from errors. Both in HD and HDR content, the image has a noticeably too warm hue – it has a slight pink tint, which is particularly noticeable in snowy scenes. Instead of pure white, we get a pinkish coating that spoils the natural perception of colours.

The management of brightness is also lacking. In the case of older HD materials, the image often seems too dark – confirmed by an elevated gamma value. Conversely, with HDR content, the effect is the opposite – the image is overly bright, as we observed in scenes from the film Pan. Such a lack of consistency also affects colour accuracy – a test with a ColorChecker showed that many samples clearly deviate from reference values.

Fortunately, TCL allows for manual adjustment of settings, so we decided to check how the television would perform after our professional calibration. The effects of this adjustment are described below.

The new feature in TCL TVs 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 regarded as the one that best represents the original vision of the creators and is often recommended by enthusiasts of good picture quality. 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 flaws. One could critique the incorrect white balance, particularly the slight dominance of blue, which caused cool, slightly greyish skin tones. But that was not the biggest issue. The main complaint was the excessive brightness exposure, which is clearly visible on the gamma and EOTF graphs. The picture was simply too bright, at times even blown out, which affected not only the richness of the scenes but also the overall viewing experience. Some details were simply lost, and the whole image looked as if someone had overdone the brightness slider a bit. As always – we decided to see what could be squeezed out of this after calibration. And that’s where it started to get really interesting…

After our professional calibration, the TCL A300 has literally been given a new lease on life. The image has stopped being too warm, and the colours finally look as they should – as confirmed by the ColorChecker test, where the colour samples finally started hitting their marks, at least to some reasonable degree. It was also possible to partially correct the brightness management – the image is now more balanced and less "wobbly" between different types of content. Of course, certain limitations can't be bypassed – a slightly visible blooming effect still occurs, but that's a characteristic of the technology, not something that can be eliminated even after professional settings.

Generally: after calibration, the A300 looks significantly better and gains a whole new quality.

After calibration, the TCL C7K put on a really good show, especially when it comes to SDR content. We managed to precisely tune the white balance, colour gamut, and brightness characteristics, resulting in colour errors on the ColorChecker palette dropping below a value of 2. For the uninitiated – this is an almost perfect score, meaning the image is very close to what the creators intended. Unfortunately, things didn’t look as good with 4K HDR content. While we managed to slightly calm down the white balance and correct its previous errors, it still shows that the TV has some "MiniLED traits," especially in brightness management. When we checked how the C7K handles the EOTF curve on actual 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 – blacks lose 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 tuning of colours, natural skin tones, and pleasant brightness make movie sessions and everyday content viewing more than satisfying.

TCL A300 handles tonal transitions in high-quality films very well, but the question arises – how does it perform with weaker materials? The TV is equipped with a tonal smoothing feature; however, its effectiveness can be described in one word: “random”. In one scene, it may work and improve the gradation, but when turned off… the effect remains the same. There is a lack of consistency and predictability here.

Image scaling is also not one of A300's strong points. On the test pattern, the main character actually looked better than on the raw signal, but with thin lines – like fonts or background details – there was noticeable jaggedness and aliasing. On the plus side, the TV does not cut off the image and has no issues with overscan, but the overall quality of scaling is rather average.

TCL C7K comes with a feature that, according to the manufacturer, aims to smooth out unwanted colour transitions – something like a rescue for less successful tonal changes. 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. And worse still – the feature can cut out elements from the image that should remain. Fortunately, film grain is left untouched, so at least it doesn't smooth everything indiscriminately, but even so – it's best to just 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 felt that the image loses sharpness and becomes too soft – as if something had taken 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.

TCL A300 is equipped with a 144 Hz panel, which should instantly satisfy virtually everyone - both gamers and sports fans. Motion is fluid and the image is clear even during fast scenes. Additionally, the television offers a motion enhancement feature called "Motion," where we find two sliders on a 10-point scale. These allow you to adjust the effect to your own preferences - from a classic, filmic look with visible frames to a very smooth (though already unnatural) image reminiscent of a soap opera effect. This way, everyone can find a setting that suits them.

TCL C7K handles motion smoothness really well. The panel used in it offers a refresh rate of 144 Hz, which alone suggests that this TV is more than just a regular "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 section for gamers and PC compatibility. Returning to everyday use – both sports and movies look very good here. Thanks to the quick panel and the well-functioning motion smoothening feature, the C7K is great for watching matches as well as for movie screenings. In the menu, we find two sliders – blur reduction and flicker reduction – that allow adjusting the smoothness effect to personal preferences. At lower settings, we get a more cinematic effect, with a slight judder. At higher settings – the image becomes more theatrical, smoothly even to excess. Whatever your taste, everyone can set it to their liking.

The TCL A300 is a television designed not only to transport us to a digital art museum but also into the full-fledged world of gaming. It offers practically everything you can expect from gaming hardware: two full-bandwidth HDMI 2.1 ports, 144 Hz refresh rate, support for VRR and ALLM.

It also deserves credit for the proper implementation of the HGIG mode – something that competing Hisense sometimes struggles with. The television handles lower resolutions (e.g., Full HD) with ease while maintaining high refresh rates, which will be appreciated by owners of older consoles or PCs.

Additionally, there's an attractive and clear GameBar that facilitates quick access to settings for gamers. The A300 is indeed well-prepared for gaming at the highest level – it’s just a shame that issues with ghosting somewhat detract from its overall appeal as a gaming device.

TCL C7K is a TV that on paper looks like the dream gear for a gamer – and most importantly, it also holds up 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, making use of all their capabilities. The panel itself supports a refresh rate of 144 Hz, which gives a considerable advantage in fast-paced games. On top of that, it comes with a full suite of gaming features: VRR (variable refresh rate), ALLM (automatic low latency mode), and Dolby Vision support in games. There’s also an HGiG mode that provides an HDR effect aligned with the creators' intentions. GameBar, which is an information bar for gamers. It operates quickly, looks clear (like a Nintendo console👌), and displays what matters most: the current frame rate, VRR status, and even HDR parameters.
