LG NANO82T6B vs TCL C655 / C69B (43" - 50")

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.

The quality of the HDR effect in the TCL C69B / C655 television is quite average. With a brightness level of 350 nits, although not the worst, it still doesn't allow for a full enjoyment of HDR effects, which require higher luminance to showcase their power. Additionally, despite the application of a quantum dot coating (QLED), the television offers an average coverage of the wide DCI-P3 colour gamut at 91%, which may limit its richness of colours in HDR content.

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.

The television TCL C69B / C655, tested in movie mode, unfortunately does not meet expectations in terms of colour accuracy. Although movie mode suggests better representation, it has almost nothing in common with film. There are many errors evident, particularly in white balance – for both HD and 4K HDR content – where the dominance of the blue colour is very noticeable. For the viewer, this means that the image becomes unnaturally cool, affecting the overall perception of colours and the visual impression. The colour checker confirms these errors, showing that colours shift towards cooler shades.

As for brightness characteristics and the related contrast, gamma is very unstable for the material, which can make the image slightly darker. The EOTF curve for the 4K material shows some errors, with significant deviations towards the end of the graph, which negatively impacts the reception of darker parts of the image.

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 calibration, the movie mode on the TCL C69B / C655 television improves in quality. The greatest improvement can be seen in tonal quality, and the white balance presents itself much better – with no major errors. We will no longer see an excessive dominance of cool tones. Gamma has also been improved, leading to a more stable representation of brightness and contrast. However, due to limitations in the form of the television's average colour palette, Colour Checker tests for 4K materials did not achieve remarkable results. Despite these technological limitations, the image has become more authentic, positively affecting the reception of film content.

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.

The "Gradual Smoothing" function works very well on the TCL C69B television and, surprisingly, does not remove desirable effects such as film grain – unlike some solutions from other manufacturers. When it comes to image scaling, unfortunately, it looks poor. The television artificially sharpens the image, causing the edges of objects to be quite jagged. This state of affairs may appeal to some users who prefer a more "hard" look to the image, but it is not an ideal solution for those who value naturalness and fluidity of details.

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 C69B / C655 television in its smallest variants offers decent, though not perfect, results in terms of motion smoothness. For films, the television features a "Flicker Reduction" function that allows adjustment of motion smoothness on a scale from 1 to 10. With this option, we can tailor the appearance of the image to our cinematic or more theatrical preferences (with either lower or higher speed).

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 C69B / C655 television in its smallest variants offers a range of features dedicated to gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the television to low latency mode, improving responsiveness and minimising delays in control. VRR allows the screen refresh rate to synchronise with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay. Dolby Vision for gamers ensures better colour and contrast reproduction in games that support this format, resulting in enhanced picture quality. Meanwhile, Game Bar provides quick access to game settings and monitors key parameters such as input lag.

However, the television has certain limitations that may affect gaming comfort. The 60 Hz panel does not allow for displaying signals with higher refresh rates, which may impact the smoothness of the image in fast-paced games. The lack of support for G-Sync technology for PCs may also be noticeable when gaming on a computer, especially in demanding, fast-paced titles.
