 I'm guessing that you are using UEFI.
 SCFB uses the GOP mode set by loader (or the default one), on my last
laptop (an HP840G3) if I leave the bios with the default config for
video memory I cannot go higher than 1280x1024, I need to set it to an
higher value and then the UEFI firmware provided multiple GOP mode.
 You can list/change the available mode in loader.efi with the 'gop'
command (gop list, gop get etc ...)
