Hi,
I notice that much depends on the zoom factor.  At some zooms there is
not much difference between display quality in  ImageJ compared to other
programs.  At other zooms there is a difference.  Here is an example.

For this image at 33.3% the two ImageJ displays are indistinguishable
and are similar to PSP fastest quality.  PSP best quallity is smoother
as is Irfanview.

Here are some links to screenshots of a 33%zoomed image.

By the way, I can't quote a previous message using my Thunderbird email
program.  If I do I get this obnoxious message:

Your posting  to the  IMAGEJ list  has been rejected  because it  only
contains
material in a format disallowed by the list configuration. Even though
the list
is configured  to remove unwanted material  and process the remaining  
text, in
this case there  would be nothing left after removing  the disallowed
material.
You may want to resend your message in plain text, which is always allowed.
