Try the system BIOS, it may have a monochrome / EGA-VGA setting.

Additionally, you say that you have the EGA card set for 80 column
monochrome - this won't work properly with a CGA monitor.  Can you set the
card to CGA?

monochrome pinouts

1 ground
2 ground
3 not used
4 not used
5 not used
6 +intensity
7 +video
8 +horizontal
9 +vertical

CGA pinouts

1 ground
2 ground
3 red
4 green
5 blue
6 +intensity
7 reserved
8 +horizontal
9 + vertical

If you plug a CGA monitor in to a monochrome card it doesn't get any
red-green-blue signals.
