How do I share my screen in Video Call? Start by creating video room with a single person or a group. Click the share screen icon in the call bar section during the call. Select the screen you want to share if you're using multiple screens. If you are using chrome browser it may request you to allow camera and microphone extension. Select stop sharing if you wish to finish share screen. Still having trouble? At the bottom right of the Zillable home page is our Help button, which allows quick access to the Zillable Help Center.
