LG NANO82T6B vs TCL C7K / QM7K 50"

The brightness of the LG NANO82T is rather average, especially compared to other TVs in a similar price range. With a peak brightness of approximately 280 nits, it falls short of many competitors offering levels exceeding 400-500 nits. This limitation impacts the viewing experience, particularly for HDR content. Bright areas of the image may lack definition, and the HDR effect fails to deliver the dramatic impact expected from higher-end displays, making the overall image less striking in well-lit scenes.

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.

The colour reproduction in the LG NANO82T in Filmmaker mode, while the best factory setting available, does have flaws. The primary issue lies in white balance, where measurements reveal a drop in the level of blue. This shifts towards yellow hues, making the image warmer than intended. Such deviations prevent natural colour reproduction, especially in scenes with white or neutral backgrounds. For instance, in Star Wars, where numerous elements should appear white, the colours deviate noticeably. The Color Checker test corroborates this, showing some shades "escaping" into others, further highlighting the lack of accurate colour rendering.

In terms of contrast, the gamma graph analysis showed a drop to 2.1, falling short of the optimal 2.4. This leads to darker parts of the image appearing brighter, reducing depth and dynamism. Additionally, the EOTF curve, which governs brightness reproduction, shows a slight spike at the start. This can result in an excessive brightness boost in the brightest areas, causing 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 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...

After calibration, the colour reproduction in SDR content on the LG NANO82T is impressive. The white balance has been effectively corrected, resulting in natural, balanced tones across various scenes. Gamma adjustments ensure more precise rendering of details in shadows and bright areas, enhancing the viewing experience. These improvements allow the television to perform well in everyday use, delivering solid colour accuracy and well-balanced images in SDR mode.

Unfortunately, the situation with HDR content is less satisfactory. The TV lacks support for a wide colour gamut, limiting the depth and richness that HDR can achieve. The EOTF curve deviates from the ideal, leading to overemphasis on details in brighter areas. This causes noticeable colour reproduction errors, as confirmed by Colour Checker tests. Additionally, the panel's low brightness further hampers HDR image quality, diminishing dynamic range effects and causing colours to appear washed out.

Overall, the TV significantly improves after calibration, particularly in SDR mode. The enhancements to white balance and gamma elevate image quality, offering more natural and cohesive colour reproduction. Compared to its pre-calibration state, the difference is evident, and the television now performs noticeably better in standard dynamic range scenarios.

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.

The LG NANO82T features a "Smooth Gradation" option for handling tonal transitions in low-quality materials. The "Low" setting improves the most problematic transitions, providing a noticeable and helpful enhancement. However, the "High" setting, while further smoothing tonal transitions, sacrifices some detail in the process. This can be a compromise that not all viewers will appreciate.

The image scaling on the LG NANO82T has some limitations, particularly when displaying lower-resolution content. The TV applies a subtle artificial sharpening, which makes the image appear sharper, but this effect is mainly due to artificial contours. Some users may find this beneficial, as it highlights details more prominently, but for others who prefer a more natural image, it may appear overly processed and artificial. This is a subjective preference that varies from viewer to viewer.

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.

LG televisions, including the NANO82T, come with an interesting motion smoother called TruMotion providing users with control over the quality of films they watch. The TruMotion feature allows adjustment of the motion fluidity on a 10-point scale, offering a personalised visual experience.

However, when it comes to more dynamic content, such as games or action films, the performance falls short. With its 60Hz panel and relatively slow pixel response, motion fluidity is less than ideal. This results in noticeable trailing and less smooth playback during fast-paced scenes.

Overall, the LG NANO82T is a good option for those who primarily watch movies and prefer more subdued content. Viewers who prioritise fast, dynamic motion, may prefer an alternative model.

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.

When playing on the console, the LG NANO82T offers several features that can enhance the gaming experience, though it also has some limitations. Notably, the ALLM (Auto Low Latency Mode) feature stands out, automatically adjusting picture settings to switch the television to low latency mode, which is especially beneficial for gamers requiring quick reactions. Another advantage is the support for HGiG (HDR Gaming Interest Group), ensuring HDR games are displayed as intended by the creators and providing vibrant and realistic visuals. These features contribute to a solid gaming experience, but there are some drawbacks, particularly in fast-paced scenes.

The LG NANO82T has limitations when it comes to advanced gaming features. It lacks support for variable refresh rate (VRR), which affects gameplay smoothness, especially in more dynamic games. The TV's 60Hz panel restricts the ability to use higher refresh rates, a significant downside for gamers seeking smoother gameplay at higher resolutions. Additionally, the absence of G-Sync technology limits image synchronisation, potentially leading to tearing and stuttering during gameplay.

These limitations mean that while the LG NANO82T offers a good gaming experience for casual gamers, it may not meet the expectations of more demanding players seeking advanced features and maximum image fluidity.

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

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.
