I don't know if this will help, but here's some info I was sent (from HP)
on 98751 monitors in November, 1993 ... maybe it will enable someone
else to give you a good answer!  If you don't get an answer, post the
same question on comp.sys.hp.hpux ... where I got this info in 1993...
 
Timing summary for HP-CCMO monitors
 
All of our monitors for a given resolution (1024 x 768 or 1280 x 1024) use
the same timing.  In addition, the following signal/input specifications are
common to all:
 
1. Input connectors and impedance:  Separate BNC connectors for Red, Green, and
                                    Blue.  75 ohms impedance.
 
2. Signal levels:  Signal levels per EIA standard RS-343A; white positive.
                   Composite sync to be supplied on the Green signal only
                   (Note: horizontal sync pulses need not be supplied during
                    the vertical sync pulse.)
 
3. Timing
 
       All signal timing is +/- 5%.
