The instruments that you have do not all have the same horizontal sync rates, and they used different monitors.

The 8591C has the same sync rate as the 8591E, which is 15.75 kHz, while the 8591As have a sync rate of 19.2 kHz. So you will need different monitors for each...

The OmniVision monitors you mention are the 15.75 kHz variety and were previously sold by Agilent as part of the 08590-60377 assembly for display replacement.
