state of power management shall be activated by the host computer terminating the appropriate sync
signals. Blanking the video must precede termination of the sync signals. The elapsed time counter
shall also be controlled by the host computer. Reactivation of the monitor shall be accomplished from
the host computer by re-establishing the normal sync signal.
