How To Connect iOS to a big screen
1 Turn on mirroring
Open Control Centre on your iOS device, then tap Screen Mirroring to show a list of receivers you can share your device’s screen with. Select your Apple TV, then type the passcode that appears on your television (if one is set).
2 Connect your keyboard
Go to Settings > Bluetooth on your iOS device and make sure the feature is turned on. If your keyboard has a pairing button, press that now. It should appear under My Devices in the Bluetooth settings – tap its name to connect it.
3 On the big screen
Anything you do on your device will be mirrored on your TV, with your TV essentially functioning as a large display for your iPhone or iPad. Glance at your device as you navigate or start moving things, then back at the TV to complete.
