Using Google Cast, there is a drop down arrow by the "Cast To" field. It gives you the opportunity to cast your desktop to TV. I haven't finished setting up openLP yet, however because I'm struggling to import the Bible versions we need for the service as I don't know where to get the Bible file it is requesting. I'm just praying that once I've got it up and running, I'll be able to use the "Cast Desktop" feature. If that doesn't work, can anyoneprovide any other alternatives?
