LG NANO82T6B vs TCL C75B

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.

During our brightness test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the TV performs decently in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the coverage of the DCI-P3 colour gamut at 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 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.

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

An additional problem was the way brightness was reproduced. 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 black (e.g., the bottom part of the screen in the comparison image - the area around the actress's ear). The situation was similar on the EOTF curve, which was below the correct value, suggesting that a similar issue may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and check how much could be extracted from this model after professional calibration. The details are described in the next section.

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, TCL C75B has clearly improved when it comes to colour reproduction. Although the TV doesn't offer too many options for adjusting the white balance, we managed to improve its settings quite a bit. As a result, the image is no longer overly pink, and the colours now look much more natural and harmonious.

The gamma jump that was previously an issue hasn't completely disappeared, but we were able to significantly reduce it. This has made details in dark scenes more visible – both in HD and 4K HDR content.

Unfortunately, the lack of local dimming is still noticeable. The 'blooming black' effect remains, but that's a limitation of the display itself. Still, the colours post-calibration look significantly better, and the image is much more pleasant to watch.

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

Image scaling is better. The TV handles it quite decently, although on thinner elements, like branches in the background, you can see slight jaggedness. However, this is not something that significantly hinders everyday viewing.

Unfortunately, a bigger problem turned out to be overscan, or cropping of the image edges. In our tests, it happened that news ticker or other elements close to the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the TV for watching news programs or content with text on the screen.

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 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 budget range.

On top of that, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-point scale, providing significant personalisation possibilities – everyone can set the smoothness to their liking.

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 C75B is undoubtedly a television designed with gamers in mind. It has almost everything needed for even the most demanding console users. With the implementation of full bandwidth HDMI 2.1, the TV supports features like ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating within the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detailing in HDR-optimised games. C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where you can check all key parameters such as refresh rate, input lag, or picture settings – all just a click away.

In one sentence: C75B is a great choice for gamers, offering a wide range of features that fully enable enjoyment of the capabilities of modern consoles and games.
