This functionality allows a computer’s graphical output to be mirrored or extended onto a secondary display. For example, a presentation can be shown on a large projector while the presenter’s notes remain visible on their laptop screen. Different configurations, such as duplicating the primary display or spanning the desktop across multiple monitors, offer flexibility for various use cases.
The ability to utilize multiple displays enhances productivity and offers significant advantages in numerous professional and personal scenarios. From graphic design and video editing to software development and gaming, expanded screen real estate facilitates multitasking, improves workflow, and provides a more immersive visual experience. This capability has evolved alongside advancements in graphics card technology and operating system features, becoming an integral part of modern computing.
