Hilary,
You may not be done yet. The SONY monitor has a traditional 75 ohm termination
on the composite sync line, just as it has on R, G, & B. The Amiga won't drive
this well enough for the Toaster to gen-lock properly. (With such a low line
level, the Toaster doesn't always detect composite sync; it needs to look at
composite sync in order to close the gen-lock loop.)
Since the 1084 presents an impedance of around 225 ohms on the composite sync
line, I've been recommending a series resistance of 150 ohms. This series
resistance can be put into the cable to save you from hacking on your Amiga or
monitor. (Composite sync is pin 10 on the 23-pin video port.)
Good luck,
