Putting (server-start) in your .emacs is most of the time not the same
as using 

emacs -Q -f server-start&

so please try that, and even better, please try what Stefan asked:

  Actually, can you just try it without any emacsclient/server?
  I.e. start Emacs on one of the screens, then do
  M-x make-frame-on-display and specify the other display.

Make sure that you use 

emacs -Q&

when trying the above.

Thanks
