Thanks Mark,

I am indeed running a laptop.  I never attach it to a CRT, the only time I
attach an
external monitor to it is when I do a presentation (maybe once a year) and I
hook it up to a projector.

I've been looking for specs on the monitor, but can't seem to find anything
more specific than stuff on the IBM product sales stuff.  Although maybe my
is only capable of 1400x1050, so maybe I'm OK where I am.

I don't have Windows or Knoppix installed on this machine, so I don't have
access to those tools you speak of.

I'll play with the refresh rates like you describe and see if anything blows
up or smokes :)
