Samsung QLED Q80D vs LG NANO82T6B

In the context of HDR, the Samsung Q80D television achieves very positive brightness results in the tested film scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing the user to experience a great juiciness of the image. Such results allow 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. test pattern 4 from the film Sicario 2), a noticeable drop in brightness can be observed, caused by the large sizes of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements against a dark background. At that point, we may perceive an unwanted lack of brightness, and the HDR effect resembles that of SDR.

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.

In "Filmmaker" mode, which is the best choice out of the box, the Samsung Q80D TV shows solid colour reproduction. For SDR content, a visible drop at the beginning of the gamma curve suggests that details in dark scenes may be less pronounced, impacting the overall viewing experience. Regarding white balance in SDR content, while it is generally accurate, significant drops in blue colour when screen coverage exceeds 70% can result in less natural hues in bright and dark scenes. Users may notice that some blue elements in the image may appear less intense, and the overall colour will have a warmer tint.

In contrast, for HDR content, the EOTF curve being above the reference line for most of the time indicates that the TV may struggle with accurately reproducing brightness and details in the brighter areas of the image, which may be disadvantageous for the viewer. It is also worth noting the substantial drop at the beginning of this graph, indicating that the TV has difficulties reproducing brightness in the darker areas of the image, as seen in the contrast and black tests, where several scenes were unable to showcase the full capabilities of the TV's brightness. In terms of its white balance, the initially good results on the graph are promising, but the sharp drop in red colour, which significantly falls down, combined with a large increase in blue colour, may lead to inaccuracies in reproducing certain 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 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 film mode after calibration looks significantly better than the one you can see when taken 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 (Colour Management System). Both in HDR and SDR mode, the white balance has improved significantly, although there are minor errors at the end of the graph in the case of HDR content. The 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 in the television seems to be at an ideal level at first glance. Yet, when we delve deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. One could even say that the television is "cheating" when playing film materials. Such a situation, where the EOTF curve is above the reference line, makes the screen – although it may seem brighter, which some users may find attractive – 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 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.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle grading, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes elements that should not be smoothed, such as film grain, to become blurred. For those who value a pliable, smoothed image more, this can be seen as a significant advantage, especially for lower-quality content.

When it comes to image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing viewing comfort. The television handles the conversion of lower-resolution materials well, improving their quality and detail. For example, in the attached image with the model, there are no visible artifacts or excessive fraying of branches, which attests to the advanced image processing technology.

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 Samsung Q80D television stands out very positively in terms of motion fluidity and motion blur reduction, primarily due to the applied 120Hz panel and above-average response time of the panel. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustment of smoothness on a 10-point scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of rapidly moving objects. In the UFO test, no motion blur is visible behind the moving object, and the image is not cloned forward, indicating a lack of overshoot effect.

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 Samsung Q80D television is a true 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 in 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The television also supports HGIG (HDR Gaming Interest Group), enabling optimal display of HDR content in games. Additionally, it is equipped with a Game Bar that allows quick access to gaming settings. Users of Nvidia graphics cards will also be pleased thanks to the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision mode, which may be disappointing for users looking for this HDR format. It is also worth mentioning that since 2022, thanks to a partnership with Microsoft, Samsung televisions offer the Xbox Game Pass application, allowing for cloud gaming. This is an additional advantage for gamers who want to access a wide library of games without the need for a console.

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.
