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. If an update is available, follow the instructions to install it. After you're connected, select Firmware on the left side of the navigation pane in the app. The app provides connection instructions. If pressing the Connect button in action center doesn't find your device, try the following: Download now Open the Wireless Display Adapter app and connect to your adapter.
