My Piper computer is up and running (Yeah!) but when I try to use an HDMI screen other than the the Piper screen the Pi goes into perpetual bootup mode where it scrolls all the startup text, then pauses and goes back to red blinky where it starts all over again.
Do I have to have my other monitor set to a particular resolution or is there something else that I am missing? I know others have done this. This is a big issue because I planned to put the output to a Smartboard for the whole class to see.
