OSD (On Screen Display) is a menu that is superimposed on your screen. On the OSD Menu, you will have a listing of the available banks and channels for selection and the currently online status of each channel. You can use it to control the KVM Switch with more convenient and intuitive menu-driven operation. The OSD menu also allows you to rename your computer (up to 9 characters), and to find the specific computer by its name. It also allows you to password-protect your KVM Switch system.
