The MiracleCast project provides software to connect external monitors to your system via Wi-Fi. It is compatible to the Wifi-Display specification also known as Miracast. MiracleCast implements the Display-Source as well as Display-Sink side.

The Display-Source side allows you to connect external displays to your system and stream local content to the device. A lot of effort is put into making this as easy as connecting external displays via HDMI.

On the other hand, the Display-Sink side allows you to create wifi-capable external displays yourself. You can use it on your embedded devices or even on full desktops to allow other systems to use your device as external display.
