Amiga Maniac's adapter does not seem to be able to resolve this. 
I really wish I would not have thrown that hard drive through the screen of my nice multi-sync DELL Monitor. Of course I was not aiming at the monitor, but that's where it ended up. Sighh....
I'm not sure about the Amiga Manic's unit, but it must outputing composite video. The best way is straight RGB to a 1084 or through a Commodore adapter (RGB to VGA) to a suitable monitor like a Dell ST2023L or a few others (there's a thread on here somewhere). That wasn't the model of your multi-sync was it ;-( ?
