The LG 85QNED92AUA 85″ and the LG 86QNED9MAUA 86″ share several similarities in their display characteristics, but there are key differences. Both models feature a 4K (UHD) resolution of 3840 x 2160 px, a 10-bit bit depth, and a color range of 1070 million colors, ensuring vibrant and accurate visuals. The display types are also similar, with both utilizing a combination of Mini-LED, LCD, and LED-backlit technologies. However, the 86QNED9MAUA is slightly larger, with an 86.4″ screen size, compared to the 85QNED92AUA's 84.5″ screen size. This results in a slightly lower pixel density of 51 ppi for the 86QNED9MAUA, compared to the 52 ppi on the 85QNED92AUA.
In terms of refresh rate, the 86QNED9MAUA offers a higher 144Hz refresh rate, while the 85QNED92AUA supports 120Hz. This makes the 86QNED9MAUA potentially more suitable for high-motion content. Both models support HDR10 and Dolby Vision, but neither supports HDR10+, and both feature HLG. The adaptive synchronization technologies also differ slightly: the 85QNED92AUA supports both AMD FreeSync and AMD FreeSync Premium, while the 86QNED9MAUA only supports AMD FreeSync. This might offer a slightly more optimized experience for gaming on the 85QNED92AUA.
Both models have the same maximum viewing angles, with 178º horizontally and vertically, as well as similar additional features such as anti-reflection coating and ambient light sensors. Overall, while the differences in screen size, refresh rate, and adaptive synchronization may influence specific use cases, the overall display quality is quite similar across both models.
