[G4] G4 450 Sawtooth monitor question

[David Minger NPG Cable]

My current monitor is going periodically zapping out (screen abruptly  
goes black, flashes back on briefly, etc. -- works again for a few  
hours after it "cools off"). So I need a new monitor.

My monitor does not accept the ADC set up -- I need a monitor that  
has a separate power cord and a 14 pin connector to the computer.

Questions:
1. Anyone know the name of the type of monitor connection I'm talking  
about so I can search for it on eBay, etc?
2. Anyone know of a good place to buy such a monitor?

Best,
David M
