Is there a way to fullscreen over 2 displays?

[andris1]

As a hacky workaround I've been able to extend a borderless window across 2 monitors, but was wondering if there's a better way. I want to do essentially split screen, but using 2 monitors.

True fullscreen across two monitors isn't really possible in the traditional sense, OS fullscreen mode always locks to a single display. But the borderless window approach you're already using is actually the correct solution, not a hack.

This is the approach used by games like BeamNG.drive for example.
