THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF
THERE IS NO VIDEO INPUT SIGNAL. IN ORDER FOR THIS
MONITOR TO OPERATE PROPERLY, THERE MUST BE A VIDEO
INPUT SIGNAL.
This monitor meets the Power Management standards as set by the Video
Electronics Standards Association (VESA) and/or the United States
Environmental Protection Agency (EPA) and The Swedish Confederation
Employees (NUTEK). This feature is designed to conserve electrical energy
by reducing power consumption when there is no video input signal present.
When there is no video input signa, this monitor, following a time-out period,
will automatically switch to an OFF mode. This reduces the monitor's internal
power supply consumption. After the video input signal is restored, full power
is restored and the display is automatically redrawn. The appearance is similar
to a "Screen Saver" feature except the display is completely off. The display
is restored by pressing a key on the keyboard, or clicking the mouse.

Plug & Play DDC1/2B Feature
This monitor is equipped with VESA DDC1/2B capabilities according to the
VESA DDC STANDARD. It allows the monitor to inform the host system of
its identity and, depending on the level of DDC used, communicate additional
information about its display capabilities. The communication channel is
defined in two levels, DDC1 and DDC2B.
The DDC1 is a unidirectional data channel from the display to the host that
continuously transmits EDID information. The DDC2B is a bidirectional data
channel based on the I²C protocol. The host can request EDID information
over the DDC2B channel.
