LG NANO82T6B vs Sony X90L

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.

HDR on the Sony X90L TV looks promising. The luminance chart showed that the television has a solid power reserve, reaching a maximum of 1000 nits in synthetic tests. However, how does this perform in real-world scenarios? In scenes such as the opening of Life of Pi or the final sequence from The Meg, the TV is able to deliver this power on HDR content, reaching about 800 nits. Unfortunately, displaying small light elements on a black background, as seen in the scene from Sicario 2, poses greater challenges for the X90L – here the results drop to around 600 nits. Despite this, when compared to competing models with mini-LED technology, the effect looks very good and can shine just enough to impress us. Notably, the colour gamut coverage is commendable, with a score of 96% for DCI-P3 and 76% for BT.2020, indicating good colour reproduction 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 best mode in Sony televisions is the IMAX Enhanced mode. Although IMAX is mainly associated with the cinematic experience, here the colour reproduction out of the box is average. In the case of lower quality content, such as HD – regular television or YouTube – it is worth paying attention to the white balance. It is characterised by a deficiency in red and an excessive dominance of blue, which gives the image a pinkish hue. The brightness characteristic, or gamma, for HD content is quite decent, but a slight boost could make the image appear washed out and look as if it is behind a light fog.

In 4K HDR content, the situation looks somewhat different. The white balance shows a significant boost in blue, which causes the image to become unnaturally sharp and seem artificial. Such an exaggeration in colour reproduction may not appeal to everyone, especially if one prefers more realistic shades. Additionally, the EOTF curve in Sony X90L appears quite correct at first glance. However, at the end of the graph, some fluctuations can be seen, suggesting that the television is trying to maintain appropriate brightness to avoid overexposing larger elements.

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.

Sony offers a range of tools for improving image quality, including two additional picture modes that we decided to utilise during testing and to apply calibration to. This solution significantly facilitates the calibration process and is very effective, provided the appropriate tools are available. In the case of HD content, the white balance was almost perfectly aligned – only one shade of grey exceeds the error value of "1", which is an excellent result. The same can be said for the brightness characteristic (gamma), which presents itself nearly perfectly, with microscopic deviations on the order of 0.01.

In the case of 4K HDR content, the situation is not quite so ideal. Although the white balance has been greatly improved, it has not been possible to completely eliminate the dominance of blue colour. Nevertheless, the errors on the Colour Checker test only occasionally exceed the value of "2", which means that image distortions are practically imperceptible. As for the EOTF curve, it is worth activating the filter in the top right corner "EOTF in Films" – the graph looks correct, but the television encounters difficulties when illuminating very small elements, which is due to the limited number of dimming zones. Despite these minor errors, it is thanks to the calibration that the IMAX Enhanced mode on the Sony X90L makes watching films feel like a true cinema experience.

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 Sony X90L television features a tone transition smoothing function known as Soft Gradation, which is extremely effective. Even at the "low" option, the effects are satisfactory, but at the "medium" setting, it works like a dream – we recommend using this option for the best results. The image scaling on the Sony X90L is simply excellent. The image is not overly sharpened, which provides a natural effect and ensures that everything looks cohesive. It's clear that the engineers really focused on this aspect, creating a solution that is impressive and performs well in daily use. Because of this, even when watching content such as regular television or YouTube, where the image is not inherently stunning, one can enjoy a smooth, cohesive, and visually pleasing experience.

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.

Sony X90L with a 120 Hz panel is an excellent choice for both gamers and cinema enthusiasts. The television is equipped with the Motion Flow smoothing feature, which allows for adjusting motion fluidity using two sliders: "smoothness" and "clarity." The "smoothness" slider controls the level of fluidity in motion, which helps reduce image stuttering, while "clarity" is used to minimize blur and enhance motion sharpness, which is particularly useful in dynamic scenes.

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.

Sony X90L is a television that performs well in terms of compatibility with consoles and features for gamers. Its 120 Hz panel and two HDMI 2.1 ports with a bandwidth of 48 Gb/s allow for smooth playback of high-resolution games at a high frame rate. Gamers can also take advantage of the ALLM feature, which automatically switches the television to low latency mode, and VRR, which ensures smooth gameplay without image stuttering. The Game Bar is an additional advantage – an intuitive tool that provides quick access to the most important gaming settings and features, facilitating control over gameplay.

Unfortunately, when it comes to HDR in games, the Sony X90L has its limitations. There is a lack of support for HGiG, a standard that many gamers consider crucial for precise HDR reproduction in games. While the television supports Dolby Vision, which could theoretically improve image quality in games, the practical application of this feature is problematic. Dolby Vision in game mode is associated with very high input lag, making gameplay less comfortable and precise movements more difficult. Additionally, it is not possible to enable Dolby Vision alongside VRR. This means that despite its numerous advantages, gamers seeking the ideal HDR in games may feel a sense of disappointment.
