If its still under warrant, I'd take it back. If not, more info is needed.

The manufactured date was 2009, I just got it from a friend and I’m the 2nd user.

That is a strange one.
Check all connections are snug.
Consider attaching a second dual monitor to see if same issue.

Sorry, I found your description confusing. Pls try again with Monitor A as "new LG" one and Monitor B as the borrowed one.
