+# Multi-monitor setup #
+
+If configured to use Xinerama libraries in `congik.mk`, dwm can
+automatically detect configured screen outputs (monitor, overhead
+projector, etc.) and their resolutions and draw the windows in the
+output area accordingly.
+
+## Configuring monitors ##
+
+One of the easiest ways to configure screen outputs is via the *RandR*
+X server extension using the `xrandr` tool. Without arguments it will
+list the current configuration of screen outputs.
+
+ xrandr
+
+For each connected output the supported resolution modes will be
+printed.
+
+## Mirroring two outputs ##
+
+dwm will assume that two outputs should display identical windows and
+tags if
+* one of them is configured to display in the same area as the other
+ (``--same-as` switch)
+* they have the same resolution
+
+After connecting a monitor, this could be an example of a mirroring
+setup
+
+ xrandr --output VGA1 --auto --same-as LVDS1 --mode 1024x768
+ xrandr --output LVDS1 --mode 1024x768
+
+The `--auto` switch enables the output after it was connected.
+
+## Two independent outputs ##
+
+If two screen outputs have different resolutions, dwm assumes that
+they should display different windows and tag sets. It may therefore
+be necessary to instruct the X server via the `xrandr` tool to draw
+the outputs in different areas of the screen, as it may default to
+`--same-as` and the areas would overlap.
+
+After connecting a monitor, this could be an example of such a setup
+
+ xrandr --output VGA1 --auto --right-of LVDS1
+
+In this case the `--auto` switch enables the output after connecting
+and also sets its preferred resolution mode.
