Samsung S90D / S94D 48" (WRGB OLED) vs LG NANO82T6B

In the tested movie scenes, the Samsung S90D delivers impressive brightness levels, exceeding 800 nits in the first four shots—a very strong result. In the final shot, featuring a full-screen burst of sunlight, brightness drops to approximately 400 nits, which is still acceptable. Notably, larger versions of this model exceed 1,000 nits, offering even more impressive performance. Additionally, the colour space coverage of DCI-P3 at 97% ensures rich and realistic colour reproduction, greatly enhancing image quality. For those considering the size of the S90D, it is worth noting that larger variants with QD-OLED panels deliver even better HDR performance, making them an excellent choice for those seeking optimal visual fidelity.

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 Samsung S90D television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more demanding users. This mode may seem too warm, and users who switched from Standard mode may experience a slight shock. It is worth noting that this state of affairs is caused by poor settings, for example, in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue colour, causing colours to become warmer than they should be. In practice, this means that some shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma graph indicates slight fluctuations, causing the image to be minimally darker, especially in shadows. This may affect less distinct details in darker scenes. Meanwhile, in 4K HDR materials, the EOTF curve is above the recommended line, which leads to some parts of the image being displayed too brightly, potentially causing clipping in the brightest areas. Overall, the Samsung S90D presents a solid picture straight out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

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.

After calibration, the S90D TV delivers an even more impressive performance in movie mode. The white balance for both HD and 4K HDR content is now nearly perfect. While there are still some minor imperfections, they are so subtle that they don't significantly impact the overall image quality. The colours are more balanced, offering a natural depiction of details, especially in scenes that require precise colour accuracy.

It's important to note that the 48-inch model features a WOLED panel, which differs from the larger sizes. This results in a smaller coverage of the wide colour gamut, meaning it doesn't offer the same rich colours as the 65-inch version, which is equipped with a QD-OLED panel.

Contrast has also seen a substantial improvement. The gamma curve after calibration is much closer to the ideal line, achieving a better balance between bright and dark areas of the image. The EOTF curve, which previously showed issues with overly bright scenes, now performs much better, retaining more detail in the bright sections of the image, especially in HDR content.

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.

The S90D TV excels in smoothing tonal transitions, offering natural and seamless colour shifts. Thanks to its advanced technology, it ensures a smoother visual experience overall. The noise reduction feature can further enhance tonal transitions, making it beneficial in certain situations. However, it’s important to note that enabling noise reduction may also smooth out the film grain, which can detract from the cinematic feel. For this reason, it's advisable to use the feature sparingly, preserving the natural grain that adds depth and authenticity to the content.

Samsung continues to impress with its scaling capabilities, with the S90D effectively processing lower-resolution content. The image is sharp and clear, maintaining proper outlines and presenting details accurately. For example, tree branches are rendered well, with no noticeable jagged edges that would compromise image quality. Thanks to the effective scaling, even lower-resolution materials are displayed attractively, making it a great choice for users who enjoy content from diverse sources, such as regular antenna or cable television.

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.

The S90D TV features a 120 Hz panel, which can be "overclocked" to 144 Hz with the appropriate PC setup, delivering exceptional motion fluidity. Samsung has long offered a range of image clarity settings on a ten-point scale, allowing users to fine-tune the display to their liking. In the UFO test, the OLED panel ensures no ghosting, with pixel response being instantaneous and perfectly capturing dynamic movements. OLED technology, in this regard, is considered one of the best on the market. The image remains incredibly sharp and detailed, even during fast-paced action, making the S90D TV a top choice for gamers and sports fans alike.

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 S90D TV is perfectly designed with gamers in mind, offering four HDMI 2.1 ports that support features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HGIG (HDR Gaming Interest Group). These technologies ensure smoother gameplay and faster screen response, enhancing comfort during extended gaming sessions. The Game Bar feature also provides convenient access to settings like aspect ratio, which can be particularly useful for different game types. For PC users, the television offers an impressive refresh rate of 144Hz, with Nvidia and AMD graphics cards supporting G-Sync and FreeSync, further boosting image smoothness. While the lack of Dolby Vision support may be a limitation, it’s worth noting that this technology is less commonly used in gaming compared to movies. Nevertheless, the S90D still provides excellent features for gamers, making it a top choice for those seeking high-quality visuals and advanced gaming technologies.
