I'm pretty sure this is something that would need to be configured in the BIOS/UEFI.

@NathanOsman: Why? I have a similar situation (laptop with external monitor): After boot linux switches to the external monitor. Why shouldn't grub (be able to) do the same. Unless this function is simply not implemented.

Because Grub doesn't interact with the graphics card the same way a Linux desktop does.

First of all I want to clear something
This issue has nothing to do with your graphics card
It is all about the resolution of your displays (Either the laptop or the external display)
For Example - If your laptop screen is set 1360x768
but your external display is 1600x900
In order to show the grub menu or the BIOS of your laptop on the external display
simply set the external display's resolution to match the laptop's display resolution. don't forget to disable the laptop display before a reboot
This worked for me
