AFAIK, the default resolution for vesamenu.c32 is 640 x 480.

You should either:
_ use a "splash" file of *that* resolution; or,
_ use the 'MENU RESOLUTION' directive.

For instance, if your "splash" background is 800 x 600, then you 
would use:
MENU RESOLUTION 800 600

and all potential screens where you want to boot with this "splash" 
should support the desired screen resolution.
