Signs look best made at 1920 × 1080 (a normal widescreen TV). Make them in any tool you like and save them as JPG, PNG or MP4.
Open Schedule, press New schedule, pick the playlist, the days and the start and end times. The TVs switch over by themselves. If two blocks overlap on the same screen the calendar marks it Clashes with… — move or shorten one.
iPads don't let apps run in the background, so the app must stay open on screen. If it's closed, your TVs keep playing what they already have, but schedule changes and new content wait until it's open again.
Lock the iPad to the app (strongly recommended)
Nobody can press Home or swipe the app away until you triple-click again and enter the passcode.
Stop surprise updates: Settings → General → Software Update → Automatic Updates → turn off Install iOS Updates, and update when the venue is closed.
Most TVs open the TV app automatically when they're switched on. A few brands — TCL and some other Google TVs — block apps from starting on their own.
Install the free AVHUD Digital Signage Remote from the App Store. It finds your iPad on the Wi-Fi; tap it and press Connect. If you set an access code (Settings → Phone and tablet apps on the dashboard), enter it once.
A TV says "Reconnecting". It has lost touch with the iPad but keeps playing. Check the iPad is on with the app open and both are on the same network.
A TV isn't on the Screens page. In the TV app choose Scan network again, or use Manual entry and type the iPad's address.
The wrong thing is playing. Check the Schedule for overlapping blocks, then open that screen's settings and press Restart the screen.
The iPhone app can't find the iPad. Make sure the phone is on the same Wi-Fi, and allow local network access: iPhone Settings → Privacy & Security → Local Network → AVHUD Digital Signage Remote.
Everything stopped after moving the iPad or changing the router. The iPad probably has a new address. The TV app finds it again by itself; browser screens need the new address.
