For administrators and whoever sets up your school’s screens: what the display shows, how to set up a TV with a code, send a link to whoever runs your signage, check that it’s working, make it yours, and turn a screen off.
Someone else runs your screens? Under Settings, TV display, open the screen with Manage and email its link to them: it comes with the steps and this video. They don’t need a Club Hub account, since the link shows your events without signing anyone in.
