I didn't, but I do now.  After trying (and failing) to run it on the
console, I tried in X-Windows (the display of which is miserably
unstable at the moment).

That's one tremendous monitor you've got on DP-7.  :-)

I've got just the one monitor.  I got back:

0: +*HDMI-A-0 1920/521x1080/293+0+0  HDMI-A-0

No, I've got the +0+, too.

I'm convinced this isn't a problem in Linux.  It's something having got
wedged in the motherboard's firmware, seeing as how the blank strip
appears even when going into the BIOS.  I suspect I'm going to have to
reinitialise the CMOS ram, which I really don't want to do, though
Michael doesn't think that's the problem.  We'll see.
