What I have done for our GIGI's is to tap in to the ttl levels for
R,G,B and sync then you can use any IBM compatible ttl monitor.
I'll send you an excerpt from the circuit diagram with the required
connections if you wish.

It is however quite simple, the GIGI outputs are "analog RGB" with sync on
Green, it is all done from ttl levels with the required resistive mixing.
