Curious as to why a Sync Seperator would be useful - the monitor I was using
does handle sync-on-green, and the picture was nicely stable - I interpreted the
"out of range" message to indicate that the micro in the monitor had decided
that
the sync was not within the frequency specifications of the monitor (although the
monitor itself appeared to be handling it perfectly).

Not rgb+s, but I hooked up my ATW800 with
Sync-on-Green to my NEC
LCD ... The ATW800 has BNC connectors, and I just hacked a VGA cable
and put connectors on it ....
The result: It has a gorgeous picture, looks great and would be perfetly
usable except for the large white box covering the middle of the screen
that you
can't get rid of no-how which says "OUT
OF RANGE".
Sounds as if a sync separator would come in handy. There's the
veneered-and-generated LM1881 or you can just set up a couple of one-shots
and some support logic to do the job.
