  • What version of OpenSong is this?
  • What operating system are you running? which version of the operating system?
  • What is your screen setup? Size, relative position, scaling, settings
  • What are the settings in OpenSong, Presentation Settings, tab Options, box Monitors.
  • Do the screen numbers in the OpenSong settings match the numbers in the operation system setup?

It is very unusual that an error like this would eventually go away just by trying again.

Does this happen when you start OpenSong after the presentation display is connected and ready? It might be an issue with detecting the screen properly when it gets connected while OpenSong is already running.
