Understanding Screen Mirroring Terminology

Before diving into the specifics, it’s important to clarify some common terms associated with screen mirroring:

Mirroring: This is the most common term and refers to duplicating your laptop screen on another display. Both screens show the exact same content.
Extending: This option allows you to treat the second display as an extension of your primary screen, giving you more desktop space to spread out your windows and applications.
Projecting: While often used interchangeably with mirroring, “projecting” usually implies sharing your screen to a larger display, often a projector, but can also encompass mirroring or extending.
Casting: This term generally refers to wirelessly transmitting content from your laptop to a compatible device, such as a smart TV or a streaming device.

Understanding these terms will help you navigate the settings and options available for displaying your laptop’s screen on another device.
