We are using a Mac Mini at our church to run Graphics/Videos. The HDMI connection goes into a video switcher, the display port to DVI goes into a projector. When the mini boots, even if we make the projector primary, it's making the HDMI port into the switcher the primary. In fact, unless we pull the display port and plug it back in, the mini doesn't even know the display port is there on reboot. Any thoughts?
