The iPad is a versatile device. You can use it as a TV, a notebook, a sketchpad, a gaming console, or a laptop (with the right accessories). But one of its most underrated features is its ability to be used as a second monitor.

With Apple's Sidecar technology, you can wirelessly pair your iPad to your Mac and freely drag apps and windows between both devices. You can also mirror your iPad display for presentations, watching TV, or sharing your screen. It's simple to use, but the setup isn't obvious. Here, I break down all the steps for turning on Sidecar and using an iPad as a second monitor.

Sidecar vs. Universal Control

The iPad continues to run iPadOS while the Mac runs macOS. The benefit is the ability to use a single keyboard, mouse, or trackpad to operate both the Mac and the iPad.

Sidecar, on the other hand, solely turns your iPad into a wireless secondary display. That means you'll have to choose between using macOS or iPadOS. You can either extend the Mac operating system to your iPad or mirror the iPad to your Mac. You can use your mouse to drag apps and windows between devices, and your keyboard to type within those apps. But when mirroring, you can't control the iPad via a mouse—you'll have to use the touchscreen or Apple Pencil.
