A multi-monitor configuration involves using two or more computer screens simultaneously to enhance productivity and improve workflow. This setup allows users to extend their desktop space, making it easier to manage multiple applications, documents, or tasks at once. It is commonly used by professionals in fields like graphic design, programming, and finance. Setting up a multi-monitor configuration typically requires a compatible graphics card and the appropriate cables to connect the monitors. Users can customize their display settings through their operating system, choosing to either mirror their screens or extend the desktop across all monitors for a seamless experience.
