Working with two screens lets you work more efficiently because there’s more visual space; for instance, you don’t have to shift from one window to the other while doing research for a report since you can lay two windows or open pages side by side. Mac users may feel that their options to use a second screen may be limited, but that is not so. Read on to learn how to turn your idiot box into a work tool.

First, check what displays your Mac device supports by doing the following:

  • Click the Apple Menu (located on the left-hand side of the screen). Then click Support > Specifications.

You will then be directed to an Apple web page indicating your device’s technical specifications. Under Graphics and Video Support, you will see some details similar to the following*:

  • Intel HD Graphics 6000
  • Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 3840 by 2160 pixels on an external display, both at millions of colors
  • Thunderbolt digital video output

*This is for a MacBook Air (13-inch, early 2015).

Extended mode versus mirror mode

Connecting to an external display lets you choose between:

  • Extended mode – uses the external display to extend the image displayed on your main Mac device. To activate extended mode:
    • Click Apple menu > System Preferences > Display > Arrangement.
    • Untick the Mirror Displays checkbox.

Note: This may not work on older Mac devices such as early 2015 models or older.

  • Mirror mode – reflects or “mirrors” the exact same image on your main device onto the external screen. To activate video mirroring:
    • Click Apple menu > System Preferences > Displays > Arrangement.
    • Tick the Mirror Displays checkbox.

AirPlay mode

Those who have an Apple TV can use AirPlay to use their TV as a second screen. Apple TV is designed for use with TVs, but it can also be used to connect to HDMI-enabled computer monitors.

To use AirPlay mode as a second display:

  • Turn on your TV and Apple TV.
  • In the menu bar (the topmost bar on the screen), select the AirPlay icon, the one with a rectangle intersected by a triangle.
  • Select your Apple TV and enter the four-digit code appearing on your TV onto your Apple device.

To enable AirPlay to mirror your main Mac device:

  • Click the AirPlay icon and select Mirror Built-in Display.
  • To use your TV as a separate display, click the AirPlay icon, then choose Use As Separate Display.

To turn off AirPlay:

  • Click the AirPlay icon, then select Turn AirPlay Off.
