I created a new installer that contained three configuarations.
No Default was selected.
iHDMI-C and CRT with CRT a clone of the iHDMI-C
and CRT Only
If I install the driver and then boot with the iHDMI-C (DVI Monitor) Connected and the CRT (VGA Monitor Connected) the clone mode works with no problem. Also the single DVI: UNTIL I boot with only the VGA Connected. After that the only thing that works is the VGA.
Even if I disconnect the VGA and reboot with only DVI I get no signal
