Our Verdict
Sony X85J
LG NANO85 2021
The Sony X85J is better than the LG NANO85 2021, but they have different panels, each with strengths and weaknesses. The Sony delivers better picture quality because it has a higher contrast ratio, gets much brighter, and has significantly better black uniformity. However, the LG has wider viewing angles, so the image remains accurate from the sides.
