VESA DPMS. There is a delay of 30 seconds before the transition from on-state to power saving
state to avoid unintentionally entering of a power saving state during display resolution and
timing mode changes. During the period of delay, the LED shall indicate green color and OSD will
show “No VGA connection”. Transition from any power saving state to another can be
instantaneous. The recovery from off-state requires no manual power on.
