Sounds awfully like what I've had to deal with:  GRUB running at the
highest resolution that the graphics card could generate, regardless of
whether the scan/refresh rates were compatible with my monitor (which it
wasn't).

I don't know how you can fix that if you can't, at some stage, get to
see a display.  I was lucky enough that once GRUB had finally booted up
an OS, the OS did run at a suitable rate, and I could edit the
configuration to change GRUB's resolution.  

In the /etc/default/grub file, I added this line:

  GRUB+AF8-GFXMODE+AD0-800x600

Then ran the +ACI-grub2-mkconfig+ACI command to regenerate the config file used
at boot time.

If it's X, itself, running at the wrong resolution, after GRUB has
handed over, and if Xorg hadn't been crippled, years ago, you could have
pressed CTRL ALT +- or - to change resolutions on the fly, until
something worked.
