"Primary" and "secondary" monitors are as follows:

(display-monitor-attributes-list) =>

(((name . "Color LCD")
   (geometry 0 0 1280 800)
   (workarea 0 22 1280 714)
   (mm-size 290 180)
   (frames #<frame emacs-devel 0x105044260> #<frame *Backtrace* 
0x1199eca10> #<frame *vc-diff* 0x117dc82b8> #<frame nsterm.m 
0x121c49ad8> #<frame *shell* 0x119adf830> #<frame  *Minibuf-1* 0x119b33030>)
   (source . "NS"))
  ((name . "DELL 2007WFP")
   (geometry -1050 -880 1050 1680)
   (workarea -1050 -880 1050 1680)
   (mm-size 430 270)
   (frames #<frame nsterm.h 0x117c83fd0>)
   (source . "NS")))
