1. Use Multiple Monitors With Mac.

You can set up multiple monitors for the Mac in a variety of ways. In addition to built-in monitor, you can also connect other monitors on a Mac. If your Mac doesn’t have a built-in monitor, you can add other monitors to the first monitor you connect to. You can also mirror or extend the Mac desktop on HDTV using AirPlay and Apple TV. Below are the methods that can let you connect your Mac to multiple monitors.

This method can make one monitor as an extension of the primary monitor.

  1. Connect multiple monitors and turn on the monitor power.
  2. Click System Preferences from the Apple menu (  ) dropdown list.
  3. Click the Displays icon.
  4. Click Arrangement tab and make sure not check the Mirror Displays checkbox.
  5. As you can see from above picture, there are two monitors for your MacBook. The left one and the right one. The monitor which has a white title bar is the primary monitor. You can drag and drop the top white title bar between the two monitors to setup it as the primary monitor.
  6. Now when you move your mouse pointer to the leftmost of the right monitor, the mouse pointer will jump to the left monitor, when you move your mouse pointer to the rightmost of the left monitor, the mouse pointer will jump to the right monitor. So the mouse pointer can be used across the two monitors.
  7. You can also drag one application window from your primary monitor to other monitor. Suppose the left monitor is the primary monitor, and you open a google chrome web browser in it, if you want to display the google chrome web browser in the right monitor, just click and hold the google chrome web browser’s title bar and move the mouse pointer to the rightmost of the left monitor until you see it in the right monitor. The chrome web browser window will move also during the mouse pointer move.
  8. If you want to move the MacOS dock bar between the monitor left, bottom and right side, just right click the separator in the dock bar, and you can choose where to display the dock bar by select menu Position on Screen —> Left , Bottom, Right.
