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 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 I

C protocol. The host can request EDID information over the DDC2B

channel.

THIS MONITO WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL. IN

ORDER FOR THIS MONITOR OT 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.
