PLUG AND PLAY
Plug & Play DDC2B Feature
This monitor is equipped with VESA DDC2B 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 DDC2B is a
bidirectional data channel based on the I²C protocol. The host can request EDID information over the
DDC2B channel.
THIS MONITOR WILLAPPEAR 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 Green monitor 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 signal this monitor, following a time-out period, will automatically switch to power saving
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.
