Well, the Multiboot protocol has a way to request a specific resolution
screen, and a way to pass that information on to the booted kernel.
What it *doesn't* have is "give us the best supported resolution",
partly because "best supported resolution" is a pretty iffy concept.

There are also a lot of machines on which the sane resolution -- even
the internal screen on laptops -- isn't supported in the BIOS.

So it all depends on what you want to do.  None of this is hard once you
have specified what it is you really want.
