IF THERE IS NO VIDEO INPUT SIGNAL OR THE MONITOR CABLE HAS BEEN DISCONNECTED, THE FOLLOWING MESSAGE IS DISPLAYED: NO SIGNAL INPUT OR CABLE DISCONNECTED. This monitor 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. Plug & Play Plug & Play DDC2B Feature This monitor is equipped with VESA DDC2B capability 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.
