Depends, what you mean by "fullscreen". All too often people say "fullscreen"
when in fact they mean "borderless windowed".
The difference is crucial.
For the latter, you don't do anything short of setting some additional flags
on your window and size it to display resolution.
For the real fullscreen, you'll have to code your own engine dealing with
graphics hardware on OpenGL/DirectX level. And then get complaints from people
with more than one monitor, that they can't use both simultaneously.
