I'm having the same issue. I'm fairly sure I have the same Win7 crash report as our Swedish friend up here:

Any sort of switching causes it to crash. It's plugged into an Acer projector via a Monoprice 4x1 switch. I don't think it's the switch, as I was having the problem when it was plugged directly into the projector as well. If I turn off the projector, it reboots once I turn it back on.
I just updated the BIOS to 25 and installed the latest Management Engine. Really hope the HDMI issues are fixed soon, because this is really annoying.
