-->While options 1 and 2 will find the matching free or proprietary video-drivers for your hardware automatically, option 3 will let you choose manually exactly which driver you would like to install.

Typical use case would be when you want to create your own manjaro-architect install media as explained in detail in @Chrysostomus' tutorial.
