iPad pro and the best projector for it:
Mirroring an iPhone to a projector can be done with the help of third-party apps like AirServer. AirServer is an app that allows you to mirror any iPhone or iPad screen to your computer. Once launched, you’ll see a video feed of your device on the screen and the controls for AirServer will appear on your computer as well as your device. That way, if you need to do something else other than watch and control everything from one screen, it’s no problem at all.If you’re using a Mac, the setup process is even easier. You need to check AirServer for updates and then just drag your phone from the desktop, tap on “Display Mode” and choose Apple TV. If you have an older device, you can use Google Chromecast instead of Apple TV if that’s what the mirroring option is named in AirServer. It costs $9.99 in the App Store, but it’s well worth it if you plan on mirroring your phone to a projector often (or even occasionally). It supports iOS 8 as well so it should work with most devices out there
