It seems plausible the 1280x1024 display only works because it's using the
analog function of the connector and not the digital.  I suspect that if you
plugged another display in digitally on that port it'd still fail.

How exactly does it fail by the way, just the second display not showing an
image?

If you boot with a 1920x1080 display on the left connector, and plug the right,
what happens?  What about the reverse?  (Just trying to rule out if it's a
problem with a particular connector, or with programming an output without
vbios assistance).
