      My Windows’ firewall or anti-virus software generates a pop-up notification that ScreenBeam is trying to open a port.

      The transmitter requires Windows to temporarily open a port to stream content to your ScreenBeam Receiver. Click "Allow" if the message appears. In some cases the anti-virus software may not pop-up the notification, so you will need to manually disable the anti-virus software.
