I found a Website with the specs on the HP monitor I found.
 Could someone take at look at the specs and tell me if this is standard RGB
 ,
 or is it possibly VGA compatible ? 
It appears that this monitor is VGA compatible, if you get the correct
video cable. You need a cable with HD15 onone end, and 5 BNC connectors
on the other end.
 Monitor Specifications: (From the Website)
                        Input Signal
                             V Frequency : 75 Hz
                             Sync Signal : Separate 
VGA needs separate sync, ie, it needs to use all 5 of the BNC connectors
onteh back of the monitor.
                         Input Connector
                             5 BNC
                        Maximum Resolution
                             Maximum : 1152x870, 75 Hz
