Are you suggesting that I do both of these, or are you questioning 
whether I'm doing both?

This is my /etc/sysconfig/grub:

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
#GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.md.uuid=bde3f430:15091bce:874aaa0e:e48f341a 
rd.md.uuid=921fb4bb:6329d29b:734b1584:7f4d3dba "
GRUB_DISABLE_RECOVERY="true"
GRUB_GFXMODE=800x600
GRUB_GFXPAYLOAD_LINUX=800x600

I added GRUB_GFXPAYLOAD_LINUX when just GRUB_GFXMODE alone didn't work.

I've also edited grub.cfg manually and added "set gfxpayload=640x480":

menuentry 'Fedora (4.0.4-303.fc22.x86_64+debug) 22 (Twenty Two)' --class 
fedora --class gnu-linux --class gnu --class os --unrestricted 
$menuentry_id_option 
'gnulinux-4.0.4-303.fc22.x86_64+debug-advanced-f9576b28-3d0b-425a-9a4b-d371df2216cc' 
{
        load_video
        set gfxpayload=640x480
        insmod gzio
        insmod part_msdos
        insmod part_msdos
        insmod part_msdos
        insmod part_msdos
        ...

> Try commenting out GRUB_TERMINAL_INPUT=console

This made no difference.

> GRUB_COLOR_HIGHLIGHT="green/black"

I'm not using any theme here.

I've included my whole grub.cfg here, in hopes that helps.

Thanks,
Alex
