Miracast is a simple and effective wireless standard for screen sharing, e.g. to get an image from a computer to a projector or large screen. Miracast connects directly between compatible devices that are close to each other, and thus does not need to be connected to the Wi-Fi network.
- It is really smart in teaching scenarios, or when guests in a company who have to show a presentation in a meeting room or conference room.

Miracast is built into Windows, and on Mac computers you just need to download a Miracast app.
