You don't mention which display you are using.  I've used both the 19"
monochrome and the 19" Phillips color.  They both have 60HZ refresh
and both flicker - regardless of the room light in use.  The
difficulty you will find in discussing flicker is that some people see
it and some people don't, or rather everyone can see flicker but not
necessarily the same frequency flicker as everyone else.  I happen to
be extremely sensitive to 60HZ flicker and can see it with almost every
monitor you put in front of me that has 60HZ refresh.  The ones I
don't see it in at that refresh rate probably have longer persistence
phosphors.  

When I got my DS3100 I was told that it could be setup as a greyscale
monitor, which would have allowed me to reduce the flicker by using a
white foreground on a dark grey or black background.  Although, it
simply involved getting the right cable - which is possible because I
saw it done in the Digital sales office - the salesman couldn't get
the warehouse to release the right configuration because it was
'unsupported'.  I put up with the monochrome monitor for a couple of
weeks with the flicker and the unfocused image - which Digital could
NOT do anything about.  They gave me another monochrome monitor that
was as least as bad as the first.  They finally ended up giving me the
Phillip's 19" color, which when set with suitably dark backgrounds
reduces the flicker problem.

I now tolerate this monitor, but it is not very bright or sharp
(because of the color mask), but I at least don't get headaches
anymore.  The Sony 16" is by far the best color monitor I've seen in
terms of sharpness and brightness and non-glare.  (Now, if they could
just get rid of those annoying little support wires at the top and
bottom!)
