OK Hugues, I've reset both screens VGA disconnected & VGA connected to 800x600 by using the Windows Advanced Settings>Adapter>List All Modes in the Display Control Panel. Did you Extend displays or use Duplicate these displays in the Screen Resolution Control Panel. I'm displaying in the 1|2 Multiple Monitors mode
Recalibration done and program is still hanging. I just get the alternating text "PC" & "CVBS" when I use a white card.
You are using a MacBook Pro & Mini DP to VGA adaptor aren't you?
Edit: I looked at the .pdf and it was quite confusing with the Chinese character text and little English, especially to a non Windows type like me.
