Yes, it is very possible to use multi-scan monitors on the ST.  In
fact, if the monitor has sufficient bandwidth you can also use it
to display high-res, and thus get all three ST display resolutions
on a single monitors.

To be specific, for about the past five months I've been using a
Sony CPD-1302 Multi-scan monitor on my ST.  The monitor handles all
three resolutions fine (what few problems I have are caused by my
home-built cable; it's impedance is a little off).

The thing to watch for when interfacing foreign RGB monitors to the ST
is the signal level that the monitors expect.  The ST generates a
one volt peak to peak signal, a typical monitor wants 0.6 volts p-p.
What I did was to stick some resistors in series with each of the video
lines to drop the voltage to what the monitor wants.

For people wanting to try anything with the ST's high-res monochrome output:
The ST is switched into high-res mode by grounding the monochrome detect
line on the video connector.  The actual monochrome output is on a seperate
line.  It looks like a "rgb" output (1 volt peak to peak, etc.).  You can
control the "color" of high res mode by which of the monitor's RGB inputs
it's hooked up to; I just went ahead and connected it to all three to get
a black and white display when in high-res mode.
