Those names are not meaningless, it is just that you do not find them
helpful. The names describe the hardware port used to attach the
monitor:

Why guess ? Read the documentation for `display-monitor-attributes-list'
which describes the meaning of the list elements in great detail.
Note that you will need to take note of the `workarea' element of the
list which describes the usuable space on a given monitor (which
excludes space for toolbars etc that are not available to display a
frame).
