Our Verdict

Sony X80J

LG NANO75 2021

The Sony X80J is better than the LG NANO75 2021. The Sony is a lot brighter, the unit we bought has better uniformity, and it has a faster response time. The Sony is also flicker-free, which is great, as the relatively low flicker frequency of the LG can bother some people and cause duplications in motion. The LG can remove judder from the native apps and 24p sources, whereas the Sony can only remove judder from 24p sources.
