I can only recommend you to try out i3 on a dual screen if possible. It opens up a different world.

You can assign workspace 1-5 to monitor 1 and 6-10 to monitor 2. That creates a great workflow.

We figure out the name and resolution with xrandr. We can use this name in the ~/.config/i3/config.

There is more info on the i3wm.org website. Learn all about it there.

There is also arandr which is then graphical.

Then we set our variables and organize the workspaces.
