A:Answer Yes it uses Miracast and uses your wifi antenna to set up a direct connection rather than across the network. It doesn't have a way to enter in your wifi information for it to connect and offer screen sharing through your network. That means that it should work while you are on a VPN, assuming your VPN client does not lock down the Miracast functions. Corporate VPNs often come other fun "features" that could interfere. Some VPNs don't like your device "sharing" your wifi antenna to do a direct Miracast connection while on the VPN. This will really be a factor of your laptop or phone, not the reciever. Go into a store with your laptop or phone and test the screensharing with one of their display smart tvs. If it works there, it should work with this.
