You can mirror the main screen, this will display the same image on both screens. Or depending on your hardware you can use extended desktop, which treats the the two screens as one big screen. Take a look in Display pane of System Preferences. Stephen Botting stephen@43south.co.nz https://www.43south.co.nz Reply to this Discussion!
