LG NANO82T6B vs TCL C75B

The brightness of NANO82T, to be honest, is quite average, especially compared to alternatives at a similar price. The maximum brightness of around 280 nits is not among the highest and may affect the overall viewing experience of HDR content. While many televisions in this price range 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 defined, and the HDR effect is not as spectacular as one might expect.

During our test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. They can be considered average – the television does not perform poorly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, these results are better than those of budget models, which can achieve almost half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the positive side, it's worth mentioning the DCI-P3 colour gamut coverage of 95%. This is a very good result that easily suffices to enjoy a wide range of colours in content available on popular streaming platforms. Vivid and rich colours are definitely a strong point of this model.

The colour reproduction in LG NANO82T in Filmmaker mode, which although is the best mode available from factory settings, is not without flaws. First and foremost, the issue lies with the white balance, where a drop in blue colour levels was noted on the graph. This phenomenon results in a shift in colours towards yellow shades, causing the image to appear warmer than it should. Such a deviation means that the colours on the screen are not naturally reproduced, and this can be particularly noticeable in scenes with a white or neutral background. For example, the image below from the film "Star Wars," where there is a large amount of elements that should be white. The Color Checker test confirms that some colours are "shifting" to other shades, which means that the television is not displaying colours accurately.

Regarding 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 television may display darker areas of the image brighter in some scenes, reducing their depth and dynamics. Additionally, on the EOTF curve, which is responsible for brightness reproduction, a slight spike was noted at the beginning. This phenomenon may result in excessive brightness boosting in the brightest parts of the image, leading to a loss of detail in very bright scenes.

TCL C75B offers several picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the television struggles with some colour reproduction issues. In our tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered accurate. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit for this phenomenon turned out to be the white balance, characterised by an excessive amount of blue and red in both HD and 4K HDR materials.

An additional problem was the way brightness was rendered. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, disappearing into complete blackness (e.g., the lower part of the screen in the comparison photo - around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that we might encounter a similar problem in 4K HDR content.

Thanks to our experience and the right tools, we decided to take matters into our own hands and see how much we could extract from this model after professional calibration. We describe the details in the next section.

After calibration, the colour reproduction in SDR content on the LG NANO82T is very good. The white balance has been effectively improved, resulting in natural and balanced shades across various scenes. The gamma has also been adjusted, providing a more precise rendering of details both in shadows and bright parts of the image. Thanks to these adjustments, 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 worse. The television does not support a wide colour gamut, limiting the depth and richness of colours that HDR can offer. The EOTF curve deviates from the ideal, leading to excessive accentuation of details in bright parts of the image. Unfortunately, this results in significant colour reproduction errors, as confirmed by tests on the Colour Checker. The low brightness level of the panel further negatively impacts the quality of HDR images, causing dynamic range effects to not be fully realised, and colours to appear washed out.

The television has 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 coherent colour reproduction. Compared to the pre-calibration state, the difference is noticeable, and the television now offers better performance in everyday use, particularly in the standard dynamic range.

After calibrating the TCL C75B, it has clearly improved in terms of colour reproduction. Although the television does not offer many options for adjusting the white balance, we managed to enhance its settings quite significantly. As a result, the image is no longer excessively pink, and the colours now look much more natural and harmonious.

The gamma jump, which was previously an issue, has not completely disappeared, but we have managed to reduce it considerably. This has made details in dark scenes more visible – both in HD and 4K HDR materials.

Unfortunately, the lack of local dimming is still noticeable. The "blooming black" effect remains, but that is a limitation of the display itself. Nevertheless, the colours after calibration look far better, and the image is much more enjoyable to watch.

When it comes to gradation in very low-quality materials, LG NANO82T offers us the option of a feature called "Smooth Gradation". In the "Low" setting, this function slightly improves the most problematic tonal transitions, which is noticeable and useful for such content. In the "High" setting, it works even more effectively, improving tonal transitions, but at the expense of smoothing out those details that should not be smoothed. It is a compromise that may not please all users.

As for image scaling, NANO82T is not without certain limitations, especially when playing content with a lower resolution. The television applies a subtle, artificial sharpness boost, which makes 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 turn out to be less appealing and too artificial. It's a subjective matter that may affect viewers differently, depending on their visual preferences.

TCL C75B has a tone transition smoothing function, but unfortunately, we cannot commend it. Regardless of the selected level – low or high – tone transitions in older materials remained visible, as if the function wasn't working at all. It's hard to say anything positive about it, as in practice it seems completely useless.

The image scaling is better. The television performs quite decently, although on thinner elements, like branches in the background, you can notice slight jaggedness. However, this is not something that significantly interferes with daily viewing.

Unfortunately, a bigger problem turned out to be overscan, which is cutting off the edges of the image. In our tests, there were instances where news tickers or other elements near the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the television for watching news programmes or content with text on the screen.

LG televisions, including the NANO82T, offer an interesting motion smoother called TruMotion, which will satisfy most users who value control over the quality of the films they watch. The TruMotion feature allows users to adjust the fluidity of the displayed films on a 10-point scale, enabling the personalisation of visual experiences.

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 result in less than ideal motion smoothness. The effect is visible blurring and less smooth display of fast scenes.

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

The TCL C75B definitely has something to offer gamers. The television is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really impressive results, especially for a model from the entry-level range.

In addition, there are features for improving fluidity and reducing motion blur in films. The "Motion" option allows precise adjustment of the effect on a 10-point scale, which offers great personalisation possibilities - everyone can set the fluidity as they like.

While gaming on the console, LG NANO82T offers a range of features that can significantly impact the gaming experience, although it also has some limitations. Among the advantages, it's worth mentioning the ALLM (Auto Low Latency Mode) feature, which automatically adjusts the picture settings by switching the television to low latency mode. This is particularly beneficial for gamers who need quick responses to their actions. Another plus is the support for HGiG (HDR Gaming Interest Group), as HDR games are displayed as intended by the developers, 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, the 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, particularly in more dynamic games. The television 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 technology support limits image synchronisation capabilities, which may 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 fluidity.

The TCL C75B is undoubtedly a television designed with gamers in mind. It offers nearly everything that even the most demanding console users could need. With the implementation of fully capable HDMI 2.1, the television supports features like ALLM (Automatic Low Latency Mode) and VRR (Variable Refresh Rate) – operating within the full potential of the television, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, allowing for even better detail reproduction in HDR-optimised games. The C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where all key parameters such as refresh rate, input lag, and image settings can be checked – all within a single click.

In a nutshell: the C75B is a great choice for gamers, offering a wide range of features that allow users to fully enjoy the capabilities of modern consoles and games.
