+With RandR 1.2-enabled drivers, monitor sections may be tied to specific
+outputs of the video card.  Using the name of the output defined by the video
+driver plus the identifier of a monitor section, one associates a monitor
+section with an output by adding an option to the Device section in the
+following format:
+
+.B Option \*qMonitor-outputname\*q \*qmonitorsection\*q
+
+(for example, 
+.B Option \*qMonitor-VGA\*q \*qVGA monitor\*q
 for a VGA output)
 .PP
+In the absence of specific association of monitor sections to outputs, if a
+monitor section is present the server will associate it with an output to
+preserve compatibility for previous single-head configurations.
+.PP
 Specifying video modes is optional because the server will use the DDC or other
 information provided by the monitor to automatically configure the list of
 modes available.
