Miracast is based on the peer-to-peer Wi-Fi Direct standard. In 2017, Wi-Fi Alliance stated Miracast as a use for Wi-Fi Direct.

In 2013, Nvidia announced support for Miracast. Adapters became available that may be plugged either into HDMI or USB ports, allowing devices without built-in Miracast support to connect via Miracast. Devices that are Miracast-certified can communicate with each other, regardless of manufacturer. The Wi-Fi Alliance launched the Miracast certification program at the end of 2012. It can roughly be described as ' HDMI over Wi-Fi', replacing the cable from the device to the display. Miracast (also called screen mirroring and wireless display among other names on consumer devices ) is a standard for wireless connections from sending devices (such as laptops, tablets, or smartphones) to display receivers (such as TVs, monitors, or projectors), introduced in 2012 by the Wi-Fi Alliance.

Make sure your device drivers are up to date and the latest firmware is installed for your wireless display or adapter (see the support info on the manufacturer's website for instructions or search Microsoft Store for your manufacturer's app to help you). If it doesn't, you'll need a Miracast adapter (sometimes called a dongle) that plugs into an HDMI port.

Make sure the display you want to project to supports Miracast and that it's turned on. Make sure your Windows device supports Miracast by checking the info that came with it or by going to the manufacturer's website.
