dpd(8) BSD System Manager's Manual dpd(8)NAMEdpd — Display Port daemon.
SYNOPSISdpdDESCRIPTION
The dpd executable is a daemon intended to listen for Command + F2 on the
iMac to switch to external display input mode upon display port hot-plug.
This feature is known as Target Display Mode. It disables display and
idle sleep while in external display mode and launches an audio tool
called dpaudiothru to capture audio input and route it into the mac unit.
To go back to normal mac mode, unplug the display port or press Command +
F2 again, which will restore all settings.
dpd should only be run via launchd.
