Manages monitor positions
You may also consider installing xrandr along with arandr to assist with monitor positions, resolution and more.
sudo pacman -S xorg-xrandr
sudo pacman -S arandr
then run arandr
Find the perfect sweet spot, then create you xrandr command.
seperate each monitor with —output, and after each —output, list the specifications.
My example looks like this:
xrandr --output DP-1 --mode 1920x1080 --pos 0x0 --rotate normal --output HDMI-1 --mode 2560x1080 --pos 1920x0 --rotate normal -- output DVI-D-1 --mode 1920x1080 --pos 4480x0 --rotate normal
Put it before you start the wm in .xinitrc
