As per the title, I'm running my display on an older 23" Apple Cinema Display (because I still love it, darn it). I'm pushing it with an ATI Radeon DVI dual-link PCIe card.

It works just fine, except GRUB doesn't seem able to push out the 1920x1200 pixel resolution needed in order to show me a boot menu! So..., I keep a smaller second monitor connected as the primary display so that I can see the boot menu and boot the system (I don't use that display once booted).

This is a goofy work-around, and I'd like to just use my single display exclusively to boot the machine. I found some grub codes for higher resolutions, but not for 1920x1200. Is it capable of this? Did I just miss it?

Thanks in advance!!!
