LG NANO82T6B vs TCL C7K / QM7K

The brightness of NANO82T, to be honest, is quite average, especially when compared to alternatives in a similar price range. With a maximum brightness of around 280 nits, it is not among the highest and may affect the overall viewing experience of HDR content. While many TVs in this price class offer brightness above 400-500 nits, LG NANO82T may seem less impressive. As a result, details in bright areas of the image may be less distinct, and the HDR effect is not as spectacular as one might expect.

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.

The colour reproduction in LG NANO82T in Filmmaker mode, which is the best mode available from the factory settings, is not without its flaws. The primary issue is the white balance, where the graph shows dips in the blue colour level. This phenomenon results in a shift of colours towards yellow shades, causing the image to appear warmer than it should. Such deviation means that the colours on the screen are not naturally reproduced, which can be particularly noticeable in scenes with white or neutral backgrounds. For example, the image below from the movie "Star Wars," where there are a lot of elements that should be white. The Color Checker test confirms that some colours are "shifting" into other shades, indicating that the TV does not display colours accurately.

In terms of contrast, the gamma graph analysis showed drops to a level of 2.1, while the optimal value should be 2.4. This means that the TV might display darker areas of the image brighter in certain scenes, reducing their depth and dynamism. Additionally, on the EOTF curve, which is responsible for brightness reproduction, a slight spike was noticed at the beginning. This phenomenon may result in excessive boosting of brightness in the brightest parts of the image, leading to a loss of detail in very bright scenes.

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…

After calibration, the colour reproduction in SDR content on LG NANO82T is very good. The white balance has been effectively improved, resulting in natural and balanced hues across various scenes. The gamma has also been adjusted, providing more precise detail representation in both shadow and highlight areas of the image. Thanks to these corrections, the television performs excellently in everyday use, offering solid colour quality and clear, well-balanced images in SDR mode.

However, in the case of HDR content, the situation is not as good. The television does not support a wide colour gamut, limiting the depth and richness of colours that HDR can offer. The EOTF curve diverges from the ideal, leading to excessive highlighting of details in the bright areas of the image. Unfortunately, this approach results in significant colour reproduction errors, as confirmed by tests on Colour Checker. The low brightness level of the panel further negatively impacts HDR image quality, causing the dynamic range effects to not be fully realised, and colours appear washed out.

The television significantly improved after calibration, especially in SDR content. The improvement in white balance and gamma has greatly enhanced image quality, providing a more natural and consistent colour reproduction. Compared to the state before calibration, the difference is clear, and the television now offers better performance in daily use, particularly in standard dynamic range.

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.

If it comes to gradation in very low-quality materials, LG NANO82T gives us the option of a feature called "Smooth Gradation". In the "Low" setting, this feature slightly improves the most problematic tonal transitions, which is noticeable and useful for such content. In the "High" setting, it works even more effectively, enhancing tonal transitions, but at the cost of smoothing out details that shouldn't be smoothed. This is a compromise that not all users will appreciate.

When it comes to image scaling, NANO82T is not without certain limitations, particularly when playing content at lower resolutions. The television applies a gentle, artificial sharpness boost, making the image appear sharper. This effect mainly results from the overlay of artificial contours. For some users, this may be beneficial, as they prefer more pronounced and highlighted details. However, for those who value the naturalness of the image, this effect may be less attractive and too artificial. It’s a subjective issue that can impact viewers differently, depending on their visual preferences.

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.

LG televisions, including the NANO82T, offer an interesting motion smoothing feature called TruMotion, which will satisfy most users who value control over the quality of the films they watch. The TruMotion function allows users to adjust the smoothness of the displayed films according to their preferences on a 10-point scale, enabling a personalised visual experience.

However, in the case of more dynamic scenes, such as games or action films, the television performs worse. The 60Hz panel and relatively slow pixel response times mean that motion clarity isn't ideal. The result is noticeable blurring and less smooth playback of fast scenes.

Overall, the LG NANO82T should satisfy those who primarily watch films and prefer more subdued content. However, for those who value dynamic, fast motion, we recommend looking for an alternative.

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.

While gaming on the console, LG NANO82T offers a range of features that can significantly impact the gaming experience, though it also has some limitations. Among the advantages, it is worth mentioning the ALLM (Auto Low Latency Mode) feature, which automatically adjusts picture settings by switching the TV to low latency mode. This is particularly beneficial for gamers who need a quick response to their actions. Another plus is the support for HGiG (HDR Gaming Interest Group), as HDR games are displayed according to the creators' intentions, providing realistic and vivid visual effects. These features make the LG NANO82T offer a good gaming experience, although some aspects could be better, especially in dynamic scenes. Unfortunately, LG NANO82T has its limitations when it comes to gaming features. It lacks support for variable refresh rate (VRR), which can affect the smoothness of gameplay, especially in more dynamic games. The TV has a 60Hz panel, preventing the use of higher refresh rates. This is a significant drawback for gamers who expect smoother gameplay at higher resolutions. Additionally, the lack of G-Sync support limits image synchronization capabilities, which can lead to tearing and stuttering in games.

These shortcomings may mean that the LG NANO82T does not meet the expectations of the most demanding gamers who are looking for advanced features and the highest image smoothness.

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.
