Thanks

Just to mention it: A previous version of this post referenced to the Multiple Monitor Panels Extension, which isn't working properly in 18.04.
In Ubuntu 18.04 there is an inbuilt setting for replicating Doc (EDIT: this answer dosen't answer the asked questions but would like to help people in replicating doc for multiple monitors so just kept it here):
