I have a Dell XPS 8700 running Windows 10, can I use miracast to send my desktop to my Sony TV (XBR55X810C) running Android TV? The TV support miracast, but not sure if my Dell does. I intend to run a long hdmi cable to the TV from my computer eventually but would like to try out miracast in the mean time.
Second question, can I use my computer as a remote - some sort of virtual remote app on my computer to change channel or launch apps. Does the Android TV OS (or app) have some sort of remote control services?
Windows 10: Settings > Devices > Connected Devices > Add a Device, your WiDi device should be listed, if not ask Dell.
Otherwise Google Cast is inbuilt, so cast tab or whole screen from Chrome.
