	Since the resolution of the Nec Multisync 3D and several others
are around 1024x768 or so, and since this is almost twice the res of
the ST's "mono" mode, this amounts to around two by two pixel groups (a
group is 1 red, 1 green, 1 blue) at the bare minimum.  In reality, just one
pixel group per displayed dot looks bad, so the 1024x768 resolution may have
more in which case there's more than four pixel groups per ST Monochrome dot.
In any case, this is on the same level as the sharpness of a scanline
boundary on the ST's mono monitor, if not better.
	I've seen several Multisync monitors running monochrome modes of
far higher resolution than the ST, and with just as much clarity.  It is
true, however, that because the ST was not "built" to work with another
monitor, impedence mismatches, interference, etc. can and will cause some
problems.  For instance, "ringing" due to impedence mismatch and other
factors seems to cause a shadow effect (I could be wrong about the cause,
this is speculation from knowledge of RF circuitry).  For this reason,
it's very important to pay attention to ground paths, circuitry, etc.

PS: No, I'm not associated with NEC.  I just like their monitors.
