The Description For OSD Message Description Auto Config When Analog signal input, if User Press Hot-Key “Auto”, will show this message, and the Please Wait monitor do the auto config function. ne t Item When the Hsync Frequency, Vsync Frequency or Resolution is out of the monitor Supported support range, will show this message. This message will be flying. Cable Not Analog-Only Model: When the video cable is not connected, will show this message.
Logo When the monitor is power on, the LOGO will be showed in the center, and disappear slowly. 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 ne t information about its display capabilities. The DDC2B is a bi-directional data channel based on the I²C protocol.
