On Windows, this is typically found by right-clicking on the desktop and selecting “Display Settings.” On macOS, go to “System Preferences” and then “Displays.” These settings allow you to detect the monitor, adjust resolution, and choose how your desktop is displayed across both screens.
Within the display settings, you can select the arrangement of your monitors (left, right, above, or below) to match their physical placement. This ensures smooth cursor movement between screens. You can also choose whether to duplicate your display (mirror the same image on both screens), extend your display (create a larger desktop spanning both screens), or show the display only on the external monitor.
What is the difference between mirroring and extending the display?
Mirroring, also known as duplicating the display, shows the exact same content on both your laptop screen and the external monitor. This is useful for presentations, where you want everyone to see the same thing simultaneously. It simplifies setup, as there’s no need to manage separate windows or applications on different screens.
Extending the display, on the other hand, creates a larger desktop area that spans across both screens. This allows you to have different applications or windows open on each monitor, increasing your productivity. You can drag and drop items between the screens, effectively doubling your workspace. Extending the display is ideal for multitasking and activities that benefit from having more screen real estate.
