I'd been assuming that was the HDMI, but maybe not? Maybe the HDMI is simply unrecognized? I'm hoping the welter of information I posted earlier can reveal that (to people who know something about this.) Note that I do get video out of the HDMI port without issue; it's not that the hardware is off.
