POWER MANAGEMENT
The power saving mode complies with the VESA Display Power Management Signaling standard. Each 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.
