tvOS adds new device management capabilities, most of which are already present on iOS. These new features make it easy to configure an Apple TV for use in many common education and enterprise scenarios, from dedicated classroom or conference room AirPlay destinations to kiosks running custom apps in Single App Mode.

Probably the easiest way to hook up an iPad or iPhone to a TV/Projector is to buy a Lightning Digital AV Adapter from the Apple Store. You will need the adapter as well as an HDMI cable. (Apple sells an HDMI cable for $29.95, but Amazon offers a far cheaper option: a basics cable.)

Using a Lightning Digital AV Adapter couldn't be easier.

1. Plug one end of an HDMI cable into the adapter's HDMI port, and the other into a spare HDMI port on the back of your TV/Projector.
2. Connect the adapter to the Lightning port on your iPad and iPhone.
3. Optional: Connect your charger cable to the Lightning port on the Lightning Digital AV Adapter.

Turn on the TV/Projector and ensure it's set to display the video input from the HDMI socket. (You generally use the remote to pick from multiple HDMI inputs on your television.) You will see the iPad or iPhone's home screen appear on the television.

Start playing a video on your iPad or iPhone. Either pick a movie file from the Videos app, or play a clip from Netflix, BBC iPlayer, YouTube, or any other video app. The Home screen will vanish from the TV, and the video will play in full definition. On the iPad you will see a screen that says TV Connected.

Mac users running OS X Yosemite or later and connected to projector can attach the iPad using its Lightning cable. Open QuickTime on Mac and choose the iPad as the camera source. 

Note: When you mirror your screen, it's a great opportunity to use your iPad as a document camera! You'll want to buy or rig up some sort of stand to use iPad as a visualizer. 

Use your iPad as a second display for your Mac with Sidecar

With Sidecar, you can use your iPad as a display that extends or mirrors your Mac desktop.

Extend or mirror your Mac desktop with Sidecar

Follow these steps on a Mac and iPad that meet the Sidecar system requirements. You can use Sidecar wirelessly, but to keep your iPad charged during use, connect it directly to your Mac with the USB charge cable that came with your iPad.

Start a Sidecar session

• If you're using macOS Big Sur, click the Display menu in Control Center or the menu bar, then choose your iPad from the menu.
   

• If you're using macOS Catalina, click the AirPlay icon  in the menu bar, then choose your iPad from the menu. (If you don't see the AirPlay icon, choose Apple menu  > System Preferences, click Displays, and select “Show mirroring options in the menu bar when available”.)

• Or just move a window to your iPad, as described in next section.

• Or connect using the menu in Sidecar preferences.

Move a window to your iPad display

If you hover your pointer over the full-screen button  of a window, you can choose to move that window to or from your iPad display. It's faster than dragging the window, and the window is perfectly resized for your display.
