Same problem here, no resolution that I have seen. Plenty of bugs open
in Fedora complaining of this and related issues:
Love to have some attention on this but I can only guess that not
everyone is seeing this. It's the only major usability issue I have
with Fedora these days but it's a big one.
I work around the issue by using the keyboard shortcut to toggle to the
mirrored mode and then once the ext display is up, I can turn off LVDS
and fix the resolution.
In related news, you might find that once this is working, it fails to
wake up after suspend and you have to do the dance again.
