Ok.  I'm sure you have some information I don't but I _know_ this isn't 
true.  I've had multiple monitors that _don't_ support sync-on-green.  
Sun monitors and other large engineering monitors are famous for it.

I'm not sure what you mean here.  All analog VGA is RGB.  Period.  
However as I stated above sync-on-green is a major issue with sun 
cards.  Basically they don't support it.  If the monitor needs it to 
operate then it's not going to work on a Sun system.

Ok.

I'm going to bet that you're not going to get it working because of the 
sync-on-green issue.

9 times out of ten if it uses sync-on-green it's for SGI.  There's a 
whole industry based on converters to supply sync-on-green to work with 
non SGI systems.

There's a blurb about it at the bottom of this page:

Said converters are here:

I'm not trying to be argumentative but I spent way too much time trying 
to get SGI branded Sony GDM model monitors working on Sun systems.  
Without a converter I've had very little success.

My advice is to buy a 13w3 -> VGA adapter and see if it "just works" on 
that connection.  If not then it's most likely a sync-on-green issue.
