Grub2 booting with dual monitors no display (flickering)

Just finished my first installation of Arch and run a Dell Latitude E6410 at work with a dock and a large external monitor hanging off the VGA port.  When the machine boots up after initial Dell screen, I get mostly a black screen with some lines of colour on the display, eventually after the usual grub timeout I see that it starts booting.  I've messed with the /etc/default/grub file and changed the GRUB_GFXMODE to something in the range of hwinfo --framebuffer with no luck (Im redoing the grub-mkconfig command after changes).

I've recently undocked the laptop and booted in a single screen and grub works perfectly, so there is obviously some issue with what display it should use or that its trying to span it across the whole range.

Can anyone share some advice on where I need to go from here?

Thanks

I've been doing some extra work to try and resolve this and I'm coming up with not many more ideas.  If anyone can point me in the right direction log file of config file, that would be great too!
