+## 
+# usb_device = "xxxx:xxxx"

+## Specify which input to switch for _all_ DDC monitors.
+## Valid values are:
+## - DisplayPort1
+## - DisplayPort2
+## - Hdmi1
+## - Hdmi2
+## - Dvi1
+## - Dvi2
+## - Vga1
+#  on_usb_connect = "Hdmi1"

+## Commands to run when display connects/disconnects
+# on_usb_connect_execute = "echo connected"
+# on_usb_disconnect_execute = "echo disconnected"
+
+## Specify display specific configution.
+## 
+## monitor_id is a case-insensitive string to search for within the monitor ID.
+##
+## Finding the monitor id is a bit of chore (as it depends on what
+## graphics driver you are using). When display_switch starts it'll
+## log all the monitors it can use including the full name of the
+## display that monitor_id is matched against.
+##
+## eg: 03:37:04 [INFO] Display 'AUS ROG XG27UQ L3LMQS072264' is currently set to DisplayPort1(0xf)
+##
+## hwinfo (avaliable in community/hwinfo) will show the monitor Vendor and Name.
+
+# [monitor1]
+# monitor_id = "aus" # 'AUS' is ASUS's vendor string.
+# on_usb_connect = "DisplayPort1"
+# on_usb_disconnect = "DisplayPort2"
