Yes, I'm not sure why this is the case. The display seems to think the mode is
only 840x1050, it cuts of the edges and does a weired scaling job.
I'm not sure why this is the case as I've never seen something like this
myself.
It could be a sync polarity problem.
Have you tried randr to change the resolution on the external panel?

I took this photo with a cellphone camera to show how badly the external
DVI-D_1 display looks like. The laptop PANEL however (not pictured) looks
good.
As you noted the xorg log suggests DVI-D_1 is trying to display 1920x1200 but
the monitor OSD says it's displaying 840x1050.
