You think only 1% of linux users have more than one monitor or a 4k screen?

I haven't looked specifically, but I don't believe you :-)  You're
telling me the apple boot
splash isn't scaled up on machines with retina displays?  I don't use
OSX (or windows),
so I don't know, but I'd be really surprised.

I'm talking about a situation where you have a dell xps or whatever
with an external
monitor attached.  Each monitor should be able to show the splash
without deforming
it, and without making it huge or microscopic. pretty basic stuff...
