LG UR781 vs LG NANO82T6B

In HDR mode, LG UR781 unfortunately does not impress with its brightness. In tests on five screens, the television achieved only around 200 nits, which is quite a low value for HDR standards. This brightness is comparable to levels typical for SDR, which means that HDR effects are not sufficiently vivid, and the picture may look less impressive, especially in dynamic, bright scenes. In HDR mode, it has certain limitations in colour reproduction. This means that colours may not be as intense and rich as in televisions that handle a wider colour gamut better. In practice, this can make the image less vibrant and dynamic, and HDR effects may not be as spectacular as one might expect. Additionally, UR781 LG has some issues with accurate colour representation in HDR mode, which makes content look less lively.

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.

Colour reproduction in LG UR781 in Filmmaker Mode, which although it is the best mode available from factory settings, is not without its flaws. First and foremost, the issue is with white balance, where the graph shows dips in the blue colour level. This phenomenon results in a shift towards yellow hues, making the image warmer than it should be. Such deviation means that the colours on the screen are not reproduced naturally, which may be particularly noticeable in scenes with white or neutral backgrounds. This can be confirmed by the Color Checker Test, which showed that some colours "escape" into other shades, indicating that the LG UR781 TV does not display colours accurately. This distortion can affect visual experiences, making film scenes seem less realistic and details may be displayed in incorrect colours, negatively impacting overall picture quality.

In terms of contrast, analysis of the gamma graph revealed drops to a level of 2.0, while the optimal value should be 2.4. This means that the TV may display darker parts of the image brighter in some scenes, reducing their depth and dynamism. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural spike was noticed at the beginning. This phenomenon may result in excessive brightness boosting in the brightest parts of the image, leading to a loss of details in very bright scenes.

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.

After calibration, colour reproduction in SDR content is quite good. The white balance has been effectively improved, resulting in natural, balanced hues across different scenes. The gamma has also been adjusted, providing a more precise representation of details in the shadows and bright areas of the image. As a result, the LG UR781 TV performs well in everyday use, offering solid colour quality and clear, well-balanced images in SDR mode.

However, the situation is less favourable for HDR content. The LG UR781 TV does not support a wide colour gamut, which limits the depth and richness of colours that HDR can provide. The EOTF curve deviates 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 the Colour Checker. Additionally, the low brightness level of the panel further negatively impacts HDR image quality, causing the effects of dynamic range to not be fully realised and colours to appear washed out.

Despite some shortcomings in HDR mode, the TV has significantly improved after calibration, especially in SDR content. The enhancement of white balance and gamma has notably increased image quality, providing a more natural and cohesive colour reproduction. Compared to its pre-calibration state, the difference is clear, and the LG UR781 TV now offers better performance in everyday use, particularly in standard dynamic range.

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.

Let's now address the function of smoothing tonal transitions and its impact on overall picture quality. As illustrated by the photo on the left, this function performs exceptionally mediocre; we chose the "low" level, which does not enhance quality but also does not blur the film grain. There is a possibility to increase the strength of this function, which could soften this gradation, but one must consider that the image will be too softened in certain scenes.

On the other hand, regarding image scaling, the television does not perform outstandingly, which may be particularly noticeable with lower resolution content. The LG UR781 television applies a slight, artificial sharpening boost, making the image appear sharper; however, this mainly results from the application of artificial contours. For some users, this may be an advantage, as they prefer more vivid, pronounced details. However, this is a subjective matter—such an effect may not appeal to everyone, especially if they desire a more natural appearance of the image.

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.

The LG UR781 TV offers quite decent smoothness for movies, thanks to the "True Motion" option, which allows users to adjust the motion smoothing level on a scale from 0 to 10. Users can choose whether they want to maintain a more traditional, cinematic effect with a slight stutter (lower settings) or prefer a smoother image with a theatrical quality, which, although slightly deviating from the cinematic standard, may appeal to many.

In dynamic sports content and gaming, the LG UR781 TV performs worse. The TV has a 60Hz panel, which limits its interpolation capabilities to these values; therefore, smoothness can be improved in films, but motion blur cannot be reduced. Additionally, the lack of support for 120 Hz and BFI (Black Frame Insertion) technology means that fast-moving objects become blurred, and the panel's response time is too slow, negatively affecting clarity in fast scenes. As a result, the TV may not meet the expectations of gamers and sports fans who are counting on a smooth, clear image without motion blur.

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.

When playing on a console, the LG UR781 TV offers several significant features that can affect the gaming experience, but it also has some limitations. On the plus side, it includes ALLM (Auto Low Latency Mode), which automatically optimises the picture settings by switching the LG UR781 TV to low latency mode, which is beneficial for gamers. The TV also supports correct implementation of HGiG, meaning HDR games look as intended by the creators.

Unfortunately, it lacks support for Variable Refresh Rate (VRR), which can result in worse gameplay smoothness, especially in more dynamic games. It also does not support Dolby Vision mode for gaming, which limits HDR picture quality in games using this format. The TV has a 60Hz panel, so it does not support higher frequencies at other resolutions, such as 1080p@120Hz, 1440p@120Hz, or 4K@120Hz, which is a significant downside for gamers expecting smoother gameplay at higher resolutions. There is also no support for G-Sync technology, which limits image synchronisation in games.

On the positive side, the presence of a Game Bar feature allows for quick access to settings for gamers and makes it easier to adjust picture parameters during gameplay.

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.
