We use a CGA LCD screen and had the same problem. I made up a Y cable, and
it worked with an IBM XTs CGA card, but not with the switchable (Herc/CGA)
graphics card (JUKO G7B) that our clones use. If I remember, the signal
wasn't strong enough to drive both monitors. I would expect a Y cable to work
in this case.

                             I think I'll go out and get one!
