It's possible to mirror from Windows 10 using the Chromium-based version of Microsoft Edge. This can be particularly useful if your device does not support Miracast (eg. desktop computers without supported Wi-Fi adapters). Microsoft Edge uses Google Cast for screen mirroring.
Casting from Microsoft Edge:
- Open up Microsoft Edge.
- Click the three dots up in the right corner.
- Click on "More tools"
- Click "Cast media to device" and then select AirServer. When clicking this for the first time, it will install a plugin for Microsoft Edge which is required for casting. After installation, you will be required to restart Edge.
- In the same menu, you can press Sources to select whether you want to mirror a tab or your whole desktop.
Please note that this functionality is only available on the newer Chromium-based version of Microsoft Edge.
Alternatively, it's also possible to mirror via Google Chrome.
