Hi Andreas,

Thank you for taking your time to reply. I've since followed up
having found the problem, and I think it must be one of the DP ports
on the graphics card.

Now, you write:

This leads me to believe that the connector hardware itself could be
at fault. Seriously, is DP *that* finicky and subject to connection
failures? I'd have thought that it being 2016, the industry would
have finally gotten the hang of it, especially after screwing up
HDMI so badly.
