As a second monitor using an iPad is an ideal solution for those who only have access to a small-screen laptop like Apple’s 12in MacBook or 11.3in MacBook Air, as it effectively increases and doubles the size of the display, enabling you to be more productive. For your Mac, keep reading on to find out how to utilize your iPad as a second screen.

What will you need?

  • An iPad
  • Lightning to USB cable

  2. Then, Head over to the Duet Display website and download the Duet for Mac/Windows app on your Mac or PC.

  5. Next, remember that by the Duet companion app iPad Pro should be recognized, and your desktop should now extend into two displays. You’re then ready to start!
