How To Optimize The DOS-Mode
Plug And Play
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.
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 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 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.
