One thing you want to do is setup the projector so it has a fixed IP address. Talk with your techie about that part. <br><br>n either case whether you're using DHCP (dynamic IP assignment) or manual IP assignment, after the projector is setup to talk on the network, go to the projector setup screen on the projector (not in OpenLP) and view what IP address the computer is using after you turn it on. The IP address that you see in the projector setup is what you would use in OpenLP Projector Manager to connect to the projector.<br><br>Also, while in the setup menu, follow your projector settings to make sure that 'PJLink connectivity' is enabled, otherwise OpenLP will not be able to connect to the projector.
