A dual monitor setup involves using two computer screens connected to a single computer. This configuration allows users to expand their workspace, making it easier to multitask and manage multiple applications simultaneously. For example, one screen can display a document while the other shows a web browser or a video call. Using dual monitors can enhance productivity, as it reduces the need to switch between tabs or windows. Many professionals, such as graphic designers and software developers, benefit from this setup, as it provides more screen real estate for their work. Additionally, it can improve organization and efficiency in various tasks.
