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

When it comes to brightness, the TCL A300W is definitely the darkest TV among all frame-style models, such as Samsung The Frame or Hisense CanvasTV – and unfortunately, this is immediately noticeable. In our measurements, the peak luminance reached only about 400 nits, and on test film screens, this value dropped to 350 nits. This is definitely too little to feel the true "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 color palette, both DCI-P3 and BT.2020. Additionally, 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 perception of materials in this quality.

In terms of brightness, the models from 55 to 85 inches in the C7K series are truly impressive. In the best testing conditions, the 65-inch screen achieved over 1200 nits, which practically means that the brightest scenes can dazzle with almost cinematic brilliance. These are not just dry numbers from measurements – during screenings, white skies, explosions, or light reflections on water looked incredibly striking, often giving the impression that the television exceeds its price class. This is particularly effective in scenes with a large area of illumination, where the screen is filled with intense brightness – such as in sun-drenched shots or during dynamic action sequences. Viewers looking for strong HDR will definitely be satisfied.

However, scenes requiring precise control of backlighting – with small points of light on a dark background – are 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 lantern or single reflections, can be less defined or blend in with the surroundings. This is a compromise inherent to MiniLED technology – it provides excellent image depth and blacks at a level that ordinary LCDs do not offer, but this comes at the cost of limited visibility of the smallest lights.

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

The brightness management doesn't perform well either. For older HD materials, the image often seems too dark – as confirmed by the inflated gamma value. Conversely, with HDR content, the effect is reversed – the image is overly brightened, which we observed in scenes from the movie Pan. This lack of consistency also affects color reproduction accuracy – a test with the ColorChecker showed that many samples deviate significantly from the reference values.

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

The novelty 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 most faithful to 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 this mode does not guarantee perfection. The Filmmaker mode in the TCL C7K is not free from flaws. One could point out the incorrect white balance, particularly the slight dominance of blue, which led to cool, somewhat grayish skin tones. But that was not the biggest problem. The main complaint was excessive brightness exposure, which is clearly visible in the gamma and EOTF charts. The image was simply too bright, at times almost blown out, which affected not only the depth of scenes but also the overall viewing experience. Some details were simply lost, and the whole image looked as if someone had slightly overdone the brightness slider. As always – we decided to see what could be squeezed out of this after calibration. And that’s when things started to get really interesting…

After our professional calibration, the TCL A300 literally got a new lease on life. The image is no longer too warm, and the colors finally look the way they should – which was confirmed by the ColorChecker test, where the color 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 cannot be overcome – a slightly noticeable 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 completely new quality.

After calibration, the TCL C7K showed itself in a really good light, especially when it comes to SDR content. We managed to 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 almost a perfect result, which means that the image is very close to what the creators intended. Unfortunately, it looked worse with 4K HDR content. Although we were able to slightly calm the white balance and correct its previous errors, it is still evident that the television has some "MiniLED traits," especially in brightness management. When we checked how the C7K handles the EOTF curve on actual film scenes, and not just on synthetic test patterns, it turned out that the screen still tends to slightly brighten the entire image. This affects the overall experience – black loses some depth, and the image becomes less contrastive 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.

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

Image scaling is also not one of the A300's strong suits. In 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 television does not cut off the image and has no issues with overscan, but the overall quality of scaling is rather average.

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 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. Worse still – the function 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 still – it's better to just turn this option off.

When it comes to scaling lower-resolution content, it's already better. SD and HD materials look quite decent, although sometimes we felt 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 was not artificially cropped – everything fit on the screen as it should.

The TCL A300 is equipped with a 144 Hz panel, which should immediately satisfy practically everyone – both gamers and sports fans. The motion is smooth, and the picture is clear even in fast scenes. Additionally, the television offers a motion enhancement feature called "Motion," where we can find two sliders on a 10-point scale. These allow for adjusting the effect to personal preferences – from a classic, cinematic look with visible frames to a very smooth (though already unnatural) image reminiscent of a soap opera effect. Thanks to this, everyone can find a setting that suits them.

The TCL C7K handles motion fluency really well. The panel used in it offers a refresh rate of 144 Hz, which in itself 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'll write more about that in the paragraph about gamers and PC collaboration. Back to everyday use – both sports and movies look very good here. Thanks to the fast panel and well-functioning motion smoother, the C7K is great for watching matches, but also for movie screenings. In the menu, we find two sliders – blur reduction and flicker reduction – which allow you to tailor the smoothness effect to your own preferences. At lower settings, we get a more cinematic effect, with a slight stutter in motion. At higher settings – the image becomes more theatrical, smooth to the point of exaggeration. Everyone can set it up according to their liking.

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

The correct implementation of the HGIG mode is also a plus – something that competing Hisense sometimes struggles with. The television easily handles lower resolutions (e.g., Full HD) while maintaining high refresh rates, which will be appreciated by owners of older consoles or PCs.

In addition, there’s an attractive and clear GameBar that facilitates quick access to settings for gamers. The A300 is truly well-prepared for gaming at the highest level – it's just a shame that issues with motion blur slightly tarnish its overall image as a gaming device.

TCL C7K is a television that on paper looks like the dream equipment for gamers – and most importantly, it holds up well in practice. First, the good news: we have two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, taking full advantage of 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 suite 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 consistent with the creators' intentions. GameBar, which is an informative bar for the gamer. It operates quickly, looks clear (like the Nintendo console👌), and shows what’s most important: the current frame count, VRR status, and even HDR parameters.
