Samsung QLED Q80D vs LG NANO82T6B

In the context of HDR, the Samsung Q80D television, as expected, achieves very positive brightness results in the tested movie scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing for a great juiciness of the image. Such results enable the user to feel the difference between HDR and SDR quality. Unfortunately, problems arise in situations where small light effects occur against a dark background. In such cases (e.g., the 4th test screen from the film Sicario 2), a noticeable drop in brightness is observed, which is caused by the large size of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements on a dark background. At that point, we may experience an undesired lack of brightness, and the HDR effect resembles that of SDR.

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.

In "Filmmaker" mode, which is the best choice right out of the box, the Samsung Q80D television shows solid colour reproduction. For SDR content, a noticeable drop at the start of the gamma curve suggests that details in dark scenes may be less clear, affecting the overall viewing experience. Regarding white balance in SDR content, while generally correct, significant drops in blue at screen coverage above 70% can result in less natural shades in both bright and dark scenes. Users may notice that some blue elements in the image may appear less vibrant, and the overall colour will have a warmer hue.

In HDR content, the EOTF curve being above the reference line for most of the time indicates that the television may struggle to accurately reproduce brightness and details in the brighter parts of the image, which can be detrimental for the viewer. It is also worth noting the significant drop at the start of this chart, indicating that the television has difficulty reproducing brightness in the darker parts of the image, as seen in the contrast and black test, where several scenes were unable to show the full capabilities of the television’s brightness. In terms of its white balance, the initially good performance on the graph is promising, but the steep decline in red, coupled with a significant increase in blue, can lead to inaccuracies in reproducing some skin tones and other key colours. This phenomenon may be noticeable to viewers in scenes where colour details are crucial.

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.

The movie mode after calibration looks significantly better than the one you see right out of the box. Samsung offers an advanced range of calibration tools in its televisions. Among them are 2- and 20-point greyscale adjustment and CMS (Color Management System). Both in HDR and SDR mode, white balance has improved significantly, although there are slight errors at the end of the graph for HDR content. Contrast has also been greatly improved, and the gamma curve responsible for SDR shows better results. However, when it comes to HDR, the EOTF curve on the television appears to be at an ideal level at first glance. However, when we dig a bit deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. You could even say that the television is "cheating" when playing film material. Such a situation, where the EOTF curve is above the reference line, causes the screen – although it may appear brighter, which some users might find appealing – to lose detail in the darker parts of the image. In practice, this means that in scenes with a lot of shadows or dark elements, the television is unable to accurately render the details that should be visible.

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.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle gradation, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes it to blur elements that shouldn't be smoothed, such as film grain. For those who prioritise a plastic, smooth image, this can be seen as a significant advantage, especially with lower-quality content.

In terms of image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing the viewing comfort. The TV handles the conversion of lower-resolution materials, improving their quality and details. For example, in the attached image featuring a model, there are no visible artefacts or excessive fraying of branches, which demonstrates advanced image processing technology.

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 Samsung Q80D television stands out very positively in terms of motion fluidity and minimizing blur, mainly due to the 120Hz panel and above-average panel response time. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustments in a 10-step scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of fast-moving objects. In the UFO test, there is no blurring behind the moving object, and the image is not cloned forward, indicating the absence of an overshoot effect.

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.

The Samsung Q80D TV is a real gem for gamers. It is equipped with four HDMI 2.1 ports, which is a rarity, especially in this price range. This allows users to enjoy features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and 120Hz at 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The TV also supports HGIG (HDR Gaming Interest Group), enabling optimal HDR content display in games. Additionally, it comes with a Game Bar, providing quick access to gaming settings. Users with Nvidia graphics cards will also be pleased with the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision, which may be disappointing for users looking for that HDR format. It's also worth mentioning that since 2022, thanks to the collaboration with Microsoft, Samsung TVs offer the Xbox Game Pass app, allowing for cloud gaming. This is an added bonus for gamers who want to take advantage of a wide library of games without needing a console.

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.
