If I read that and my thinking is right, that is what it should be.  I
don't completely understand everything that output is saying.  But, I
technically have three monitors.  I have two in front of me that have
different displays.  Those are DP2 and DP-2.  The third, DP-7, is my TV
that I watch.  It goes to a splitter which goes to a TV in my bedroom
and one in the living room.  I can cook, clean etc while watching TV. 
DP-7 is to the right of DP-2 which may be why it shows something larger. 

Some of this monitor stuff is a bit confusing.

Ahhhhh.  If it does it in the BIOS, it's either a monitor or video card,
or mobo if video is built in, problem.  If a monitor isn't right in the
BIOS screen, odds are it won't be when booted either.  Can you install a
video card and test?  If it works, mobo has a video driver problem.  If
not, could be monitor or cables or something. 

At least we know one thing it isn't.  ;-)
