Multiple Scan 20 Display: Older Video Cards Incompatible

I have a Macintosh IIfx with an 8-bit video card and a video card for a 21-inch Apple Monitor. Can I use either of these cards with the new Apple Multiple Scan 20 Display?
In this particular case it was not possible to incorporate support for the old video card technology into the new display. So, neither of these cards support the Multiple Scan display.
