Another interesting thing. I changed the boot file to only
"video=HDMI-A-1:e" and the monitor on the DVI port complains about the
resolution being to high. I then put the hdmi cable onto my dvi/hdmi
adapter and plug it into the DVI port and wala, a 1920 x 1080 desktop. So I
reboot with it in that configuration and again comes up good connected to
the DVI connector.

I'm still getting the same messages spewed into the kernel log file. So
this looks to me like the kernel is confused. Again, I ask, why do I have 3
HDMIs and 3 DPs but just one VGA.
Something is just not right here. I'm beginning to think it's not me.
