Sun uses combined H+V sync.  SGI (and DEC, and maybe others) used sync
on green.  Unless you have both, sync on green is not a requirement.
That said, nearly all current monitors support separate, combined, and
sync on green.

If your converter does not set a sense bit to tell OBP what type of
monitor you have, you will probably need to fiddle with the
output-device OBP property to achieve the desired resolution and
refresh rate.  Consult appropriate manuals to determine the OBP syntax
and supported graphics modes.  Hint: setenv output-device
screen:rXXXXxYYYYxRR normally works.

Also, UPA is not an external connector type, it is the system
communications protocol used in early ultras and for graphics devices
in nearly all ultras.  Many systems have one or more UPA slots
internally, but attempting to connect a monitor to one would be
plainly impractical.  It stands for Ultra Port Architecture.
