Samsung DU7192 (IPS) vs LG NANO82T6B

The maximum luminance for HDR content on the Samsung DU7192 is 245 nits, but is often exceeded by even lower results. Such values are insufficient for comfortable viewing of HDR material due to the lack of appropriate image dynamics and the colour distortions caused by the device's low brightness. While the manufacturer has equipped the device with an HDR format featuring dynamic metadata, specifically HDR10+, it is rarely used compared to Dolby Vision, which Samsung has yet to introduce in its televisions. It is also worth noting that the Samsung DU7192 only covers 82% of the wide colour gamut DCI-P3, meaning that sending signals in a wide dynamic range should be avoided, as significant colour loss will be evident.

Overall, the Samsung DU7192 delivers high-quality images that will satisfy most users. The television stands out particularly for its vivid colours and decent contrast. Thanks to UHD technology, the image on the screen is sharp and clear, even during fast-moving scenes. The DU7192 also supports HDR, allowing for better reproduction of details in bright and dark areas of the image.

The brightness of the LG NANO82T is rather average, especially compared to other TVs in a similar price range. With a peak brightness of approximately 280 nits, it falls short of many competitors offering levels exceeding 400-500 nits. This limitation impacts the viewing experience, particularly for HDR content. Bright areas of the image may lack definition, and the HDR effect fails to deliver the dramatic impact expected from higher-end displays, making the overall image less striking in well-lit scenes.

The best factory mode we used throughout the testing process was "Filmmaker." However, like most modes, it had its drawbacks. Starting with the most basic chart, the white balance, we observed a pronounced dominance of red in SDR and HDR modes. Although green also appeared in HDR mode, it did not significantly affect the overall perception. This resulted in an image with a noticeable yellow tint, particularly evident on the whites and the faces of the actors.

Another important chart, arguably more significant, is gamma, which controls contrast in materials with a standard colour palette. In factory mode it performed reasonably well, but with one notable issue regarding the darkest scenes. Here, it was significantly lowered, resulting in excessive brightening, which robbed the film of its contrast and suspense.

As for HDR content, the white balance remained similar. The main change occurred in the EOTF curve chart. Initially, we saw a bulge that, like the gamma curve, brightened the darkest scenes considerably. However, the curve then drastically changed, and the measured result dropped below the reference line, diminishing the dynamism of the film even further.

The colour reproduction in the LG NANO82T in Filmmaker mode, while the best factory setting available, does have flaws. The primary issue lies in white balance, where measurements reveal a drop in the level of blue. This shifts towards yellow hues, making the image warmer than intended. Such deviations prevent natural colour reproduction, especially in scenes with white or neutral backgrounds. For instance, in Star Wars, where numerous elements should appear white, the colours deviate noticeably. The Color Checker test corroborates this, showing some shades "escaping" into others, further highlighting the lack of accurate colour rendering.

In terms of contrast, the gamma graph analysis showed a drop to 2.1, falling short of the optimal 2.4. This leads to darker parts of the image appearing brighter, reducing depth and dynamism. Additionally, the EOTF curve, which governs brightness reproduction, shows a slight spike at the start. This can result in an excessive brightness boost in the brightest areas, causing a loss of detail in very bright scenes.

Samsung even with its entry-level televisions, provides advanced tools for calibration, and we put these to work. The results of our efforts were more than satisfying. The white balance, which previously had a strong yellowish tint in both scenarios, now looks much improved, although slight deviations from the ideal are still noticeable. Nevertheless, the image is significantly cleaner than before the calibration process. We were able to model the gamma well for SDR materials, achieving as much contrast as the television can provide. The EOTF curve has also been adjusted, preventing the image from becoming excessively lightened or darkened. However, it is worth noting that for HDR materials, the deltaE errors remain quite high, with the primary issue being the unit's insufficient brightness.

After calibration, the colour reproduction in SDR content on the LG NANO82T is impressive. The white balance has been effectively corrected, resulting in natural, balanced tones across various scenes. Gamma adjustments ensure more precise rendering of details in shadows and bright areas, enhancing the viewing experience. These improvements allow the television to perform well in everyday use, delivering solid colour accuracy and well-balanced images in SDR mode.

Unfortunately, the situation with HDR content is less satisfactory. The TV lacks support for a wide colour gamut, limiting the depth and richness that HDR can achieve. The EOTF curve deviates from the ideal, leading to overemphasis on details in brighter areas. This causes noticeable colour reproduction errors, as confirmed by Colour Checker tests. Additionally, the panel's low brightness further hampers HDR image quality, diminishing dynamic range effects and causing colours to appear washed out.

Overall, the TV significantly improves after calibration, particularly in SDR mode. The enhancements to white balance and gamma elevate image quality, offering more natural and cohesive colour reproduction. Compared to its pre-calibration state, the difference is evident, and the television now performs noticeably better in standard dynamic range scenarios.

Let’s revisit the smoothing of tonal transitions function. It can be set to either "off" or "auto." As expected, setting it to "off" results in significant gradation issues. On the other hand, when set to "auto," both movies and TV shows offer smoother colour transitions. However, this function has notable drawbacks: it interferes with the director’s intent by softening the effect of film grain and, more concerning, it often blurs small details, misinterpreting them in the process. For this reason, we consider this feature ineffective and do not recommend using it, as the tests for tonal transition smoothness were conducted with this function turned off.

Next, we assessed the image scaling, which is crucial for watching lower-resolution materials. Unfortunately, as this is one of the manufacturer’s lower-end models, the scaling function does not perform well. The result is heavily blurred details, and a noticeable white halo forms around characters, detracting from the viewing experience.

The LG NANO82T features a "Smooth Gradation" option for handling tonal transitions in low-quality materials. The "Low" setting improves the most problematic transitions, providing a noticeable and helpful enhancement. However, the "High" setting, while further smoothing tonal transitions, sacrifices some detail in the process. This can be a compromise that not all viewers will appreciate.

The image scaling on the LG NANO82T has some limitations, particularly when displaying lower-resolution content. The TV applies a subtle artificial sharpening, which makes the image appear sharper, but this effect is mainly due to artificial contours. Some users may find this beneficial, as it highlights details more prominently, but for others who prefer a more natural image, it may appear overly processed and artificial. This is a subjective preference that varies from viewer to viewer.

Although the Samsung DU7192 is the entry-level model in the manufacturer’s range, it does come equipped with motion smoothing technology. While this feature is somewhat limited in comparison to higher-end models, its inclusion is a notable advantage in its price category. The maximum refresh rate available on the TV is 60 Hz, which is adequate for movies and TV shows but falls short for fast-moving content like sports.

Within the motion smoothing settings, there are two features aimed at improving fluidity: "Motion Blur Reduction" and "Clear Motion (LED)." We’ll discuss the latter later, but first, let’s focus on the former. Unfortunately, despite being present, we found no noticeable difference when adjusting this setting. Regardless of the chosen option, the picture maintained the same stuttering effect typically associated with 24 fps content.

The Samsung DU7192 uses a panel with an average response time. However, it is worth noting that this type of panel outperforms VA panels in a similar price range, making it a more suitable option for watching sports compared to other budget models.

LG televisions, including the NANO82T, come with an interesting motion smoother called TruMotion providing users with control over the quality of films they watch. The TruMotion feature allows adjustment of the motion fluidity on a 10-point scale, offering a personalised visual experience.

However, when it comes to more dynamic content, such as games or action films, the performance falls short. With its 60Hz panel and relatively slow pixel response, motion fluidity is less than ideal. This results in noticeable trailing and less smooth playback during fast-paced scenes.

Overall, the LG NANO82T is a good option for those who primarily watch movies and prefer more subdued content. Viewers who prioritise fast, dynamic motion, may prefer an alternative model.

The Samsung DU7192 is equipped only with HDMI 2.0 ports, which is to be expected given the device's price point and its target consumer market. As a result, it does not support the highest resolutions or frame rates available on the latest generation consoles. It does, however, feature the basic gaming functionality of ALLM (Auto Low Latency Mode). Unfortunately, it is disappointing that the manufacturer did not include GameBar, a feature that has become a standard even in lower-end TVs. GameBar would have provided significant convenience by allowing gamers to easily adjust settings quickly during gameplay.

When playing on the console, the LG NANO82T offers several features that can enhance the gaming experience, though it also has some limitations. Notably, the ALLM (Auto Low Latency Mode) feature stands out, automatically adjusting picture settings to switch the television to low latency mode, which is especially beneficial for gamers requiring quick reactions. Another advantage is the support for HGiG (HDR Gaming Interest Group), ensuring HDR games are displayed as intended by the creators and providing vibrant and realistic visuals. These features contribute to a solid gaming experience, but there are some drawbacks, particularly in fast-paced scenes.

The LG NANO82T has limitations when it comes to advanced gaming features. It lacks support for variable refresh rate (VRR), which affects gameplay smoothness, especially in more dynamic games. The TV's 60Hz panel restricts the ability to use higher refresh rates, a significant downside for gamers seeking smoother gameplay at higher resolutions. Additionally, the absence of G-Sync technology limits image synchronisation, potentially leading to tearing and stuttering during gameplay.

These limitations mean that while the LG NANO82T offers a good gaming experience for casual gamers, it may not meet the expectations of more demanding players seeking advanced features and maximum image fluidity.

These shortcomings may mean that the LG NANO82T does not meet the expectations of the most demanding gamers looking for advanced features and the highest image fluidity.
