I have a multi-monitor system, but I'm not going to perform experiments
without a clearer recipe. I did try rearranging the physical monitor
layout as follows (which makes it quite easy to lose the position of the
cursor). Things may get more confusing with three or more monitors...
;; Two monitors arranged physically as:
;; +---------+
;; | |
;; | 2 |+---------+
;; | || |
;; +---------+| 1 |
;; | |
;; +---------+
(display-monitor-attributes-list)
;; ==>
(((geometry 0 0 1920 1080)
(workarea 0 0 1920 1050)
(mm-size 677 381)
(name . "\\\\.\\DISPLAY1")
(frames))
((geometry -1680 -646 1680 1050)
(workarea -1680 -646 1680 1050)
(mm-size 593 370)
(name . "\\\\.\\DISPLAY2")
(frames)))
(display-pixel-height) ;; ==> 1726
(display-pixel-width) ;; ==> 3600
(display-mm-height) ;; ==> 609
(display-mm-width) ;; ==> 1269

True, as long as the meaning of geometry/workarea and the coordinate
system are given a little more detail in the docs.
