    Is there a way to choose which of your two monitors shows up as the boot monitor? In other words, with multiple monitors connected, only one of the displays shows the Apple logo and would show any of these selected boot or configuration options listed in this article. The other monitor sits dark until the boot is almost finished.

    My Mac Mini has mini-displayport (via thunderbolt combo port with an adapter on it) and HDMI and the mini-dp always defaults as the boot monitor. The problem is that is not the monitor I'm using as my primary monitor (dock is on the HDMI and it's the one sitting directly in front of me). As near as I can tell, there is no way to tell OSX that I want the HDMI output as the default. If I unplug the mini-dp connector, then it appears on that monitor, but as soon as I plug it back in, it goes back to the mini-dp monitor. That monitor is often turned off as I only turn it on when I use it, but that doesn't stop the computer from sensing its presence (actually sits on standby).

    In reality, the primary monitor is DVI (Apple HDMI to DVI adapter included with Mini) and the secondary monitor is HDMI (using a generic Mini-DP to HDMI adapter). I can switch the adapters around so it's HDMI to HDMI and Mini-DP to DVI, but that puts two adapters on one cable and the cable is quite heavy at that point and frankly feels like a good bit of tug on the port which I'd rather avoid. I have no issues with the adapters themselves (both monitors work perfectly fine and it will work fine the other way around other than the weight), but it just seems like there must be a configuration setting somewhere even if only in some shell file that tells the mini which port to use as the boot default.

    Truthfully? I'd put your HDMI monitor on the HDMI port so it doesn't need an adapter and get an inexpensive mDP to DVI adapter. That way one monitor has no adapter and the other has only one adapter.

    Well, that's one way around the issue (I could probably prop the cable up for free if it came down to it for that matter), but either way I'd still like to know how OSX selects a default monitor port. It'd be nice to just be able to select the default port.
