The DIP switches tell the Mac the resolution of the screen. Some
settings are fixed resolutions, and some indicate a multi-resolution
monitor. If you choose a multi-resolution setting, you will be able to
select the resolution in the control panel.

Some really old Macs only support fixed sizes, so you'd need the adapter
with DIP switches if you were using a late 1980s or early 1990s era Mac.
I seem to recall that the original Mac LC (1990) falls into this camp. A
more modern Mac like a Quadra or PowerMac should be fine with multiscan,
and I'd expect the unswitched adapter to work.
