HOW TO OPTIMIZE THE DOS-MODE

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 communication channel is defined in two levels, DDC2B.

The DDC2Bis a bidirectional data channel based on the I

C 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.
