PLUG AND PLAY
Plug & Play DDC1/2B Feature
This monitor is equipped with VESA DDC1/2B capabilities according to the
VESA DDC STANDARD. This allows the monitor to inform the host system of
its identity and, depending on the level of DDC used, to communicate
additional information about its display capabilities. The communication
channel is divided 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.
THIS MONITOR WILLS NOT WORK 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 save 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 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. This 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.
