Sorry. I thought, that "primary" is the one, which has property "AAPL,boot-display"I'm not sure what you mean by Primary and Secondary, but if you open the Displays panel from System Preferences, you can rearrange multiple monitors. If you look carefully, one of the monitors in this multi-monitor arrangement page will have a white bar along the top, which is the Menu Bar. You can drag just this white bar to another monitor. Whichever monitor contains the white bar is the "primary".
By the way. My hack boots with only HDMI TV working and there is distorted screen for a while, then it turns black and then it works as usual. If hack goes into sleep mode, then after wake both HDMI and DVI are working.
