Use the Xinerama extension:

xdpyinfo -ext XINERAMA

You can query similar information from a program using the functions in
libXinerama.

There's documentation in man pages for libXinerama:
http://cgit.freedesktop.org/xorg/lib/libXinerama/tree/man/Xinerama.man
("man Xinerama" if you have the man page installed)

Hope that helps!
