It’s much more convenient to work when you have two monitors. In case you’re using a Mac computer (a MacBook Pro, MacBook Air, or Mac mini) and want to hook an external monitor to it, we’ve got a few tips for you.
First, check which displays your Mac device supports by doing the following:
- Click the Apple Menu (located on the left-hand side of the screen) then click About This Mac. Then click Support > Specifications (under Mac Resources).
You will then be directed to an Apple web page indicating your device’s technical specifications. Under Display and Video Support, you will see some details similar to the following:
- Retina display
- 13.3-inch (diagonal) LED-backlit display with IPS technology; 2560-by-1600 native resolution at 227 pixels per inch with support for millions of colors
- Supported scaled resolutions:
- 1680 by 1050
- 1440 by 900
- 1024 by 640
- 400 nits brightness
- Wide color (P3)
- True Tone technology
Simultaneously supports full native resolution on the built-in display at millions of colors and:
- One external display with up to 6K resolution at 60Hz
Thunderbolt 3 digital video output
- Native DisplayPort output over USB-C
- VGA, HDMI, DVI, and Thunderbolt 2 output supported using adapters (sold separately)
This is for a 13-inch MacBook Air (M1, 2020) model.
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.
- Make sure the Mirror Displays checkbox is unticked.
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.
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.
- On your Mac in the menu bar (the topmost bar on the screen), click the Control Center icon.
- Click Screen Mirroring then select your Apple TV.
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.
