Did you read the articles quoted above? All you need is an adapter to fool the Mini into thinking it's connected to a monitor.

I read the articles, but they use a VGA adapter to fix this. The 2011 version ships with a HDMI-DVI adapter. And that particular adapter does not have the analog signals used in the VGA adapter to fool the mini into thinking it has a monitor connected.
In my case it was way easier to just connect it to a monitor in a 2nd bedroom. And the performance is way better now that it has a head! Way way better.
