You're quite welcome.

That seems to be common; in the case of the FirePro 7820M in my M6500, 
triple monitor support is only available when using the two displayports 
on the dock; it doesn't work correctly if using the two DVI-D ports or 
the VGA port, at least not with this particular card on CentOS 7 with 
the stock ATI drivers.  I haven't tried with the fglrx driver; it seems 
to be a bit of a problem child on C7 at the moment.  For that matter, 
the nVidia proprietary driver is a bit of a problem child if you have 
any encrypted partitions like I do.

As I don't have anything with higher resolution than 1920x1200 with 
which to test, I can't comment on that, sorry.
