I am not sure.  On a remote Solaris system, I did

   gm display -display foo:0.0

with DISPLAY unset and it did display locally as expected.  As far as 
I am aware, -display simply copies its argument into 
ImageInfo->server_name, so this should be a useful test.  I am unsure 
about ordering requirements.  Perhaps there is a point beyond which 
the value is no longer used?

Permutations of invalid display arguments produce error messages which 
show that this value is being used.  I also tested with the DISPLAY 
environment variable set.

Does the command line -display option work for you?
