The LG 86UT8000AUA uses an 85.6″ LED-backlit LCD panel with a 4K (UHD) resolution of 3840 x 2160 pixels at 51 ppi, processed through a 10-bit colour pipeline capable of displaying up to 1,070 million colours.

The panel includes an anti-reflection coating and an ambient light sensor, and offers 178° viewing angles both horizontally and vertically.
