You could also try with: -g 1800x1080
That seems to provide a bigger screen for the firmware, at least. It does
not seem to work right with a width of 1920, though.

Hi,
For qemu-system-ppc setting e.g. -g 1024x768x32 only affects the initial size of the openbios window. To set the resolution in the guest, use the appropriate tool inside the guest. I believe the available resolutions for the guest are hard-coded in the qemu_vga.ndrv in the pc-bios folder.
See screenshot for available resolutions.
Best,
Howard
