Single Sync Woes

[Ryan L. Kitchen]

Of course I've googled and tried, albiet briefly, to find a simple (cheap) 
solution. The biggest problem I have had was basically finding information that 
repeats.  Everyone has a lot of ideas in arcane newsgroups about how you should 
get this very specific GDM-1960/1961 to work with VGA(sync on green apparently 
needs SOMETHING modified to make it work with VGA standards, but nobody agrees 
on what the SOMETHING is.)

Everyone with a business wants to sell "their" p.o.s. card to me. I was hoping 
there was a magical fix so that when I wanted to, I could plug this monitor 
into MY video card and get a display. I'm not worried about dos or game 
windows. I just want a Display in windows, period.

The info I have seen most often is 1280x1024 standard max res. with a refresh 
of 72 hz. With these settings configured, if i plug the monitor in, it doesn't 
work. This has to do with sync incompatibility that can be solved by either a) 
buying a 50 dollar converter, or building one. I would opt for the building 
portion if I could just get a clear answer on exactly how to do it. 

Thanks for the thoughts thus far....
