Can't set separate background on Antergos external monitor
 

Can't find a way to set different, separate background image on external monitor in Antergos Gnome. It seems that it is like Windows, one size fits all. ChaletOS allows me to set one for external monitor and another for the laptops', so why can't Antergos Gnome?

it is up to the background setter to do that, and up to the window manager to provide functionality to enable that.
in gnome, both are probably part of the "DE".

also depends HOW you set up those dual monitors.

all i can say, other window managers / background setters are perfectly capable of doing that.

Okay. Maybe i'll try a fresh install and see if there's something different that can be done.

(dual boot on Windows 10).
