Understanding the Basics of Screen Duplication
Before we dive into the nitty-gritty of screen duplication, it’s essential to understand the fundamental concepts involved. Screen duplication, also known as screen mirroring or screen extension, is the process of reproducing your computer or mobile device’s screen on an external display, such as a projector. This feature allows you to mirror your screen, extend your desktop, or create a separate display for presentations, videos, or other content.
Types of Screen Duplication
There are three primary types of screen duplication:
- Mirroring: This type of duplication creates an exact replica of your screen on the projector, ideal for presentations, videos, or demonstrations.
- Extending: This type of duplication allows you to use the projector as a secondary screen, giving you more space to work with multiple windows, applications, or files.
- Second Screen Only: This type of duplication sends the video signal to the projector only, turning off the screen on your device. This is useful for presentations or videos where you don’t need to interact with your device.
