If you have a card that outputs sync-on-green you can connect the green
output to green and the 1 or 2 separate sync inputs.  The levels should be
correct.  The only problem is that each input is probably terminated so the
green driver will see a 37.5 or 25 ohm load instead of 75 ohm unless you
can disable the termination on the monitor somehow.  Do the daisy chaining
at the monitor end of the cable, not the card end, and put the terminated
input at the end of the daisy chain if you can.

Some monitors with 4 or 5 inputs will still take sync-on-green inputs.
Some monitors will have switches to control sync and/or termination options
(perhaps internally).  Try taking the cover off to see what's there.

Signature failed Preliminary Design Review.
Feasibility of a new signature is currently being evaluated.
