Gotta be something hardware specific to you like the other guy said cause I literally just did a fresh fedora install on a 4K display a few months ago with zero issues, and majority of people I know also use 4K displays for their Fedora workstations, and that has never once been brought up as an issue. Maybe search around for whatever hardware you’re running, otherwise I really have no idea what would cause that.

It’s a fairly large display, it could be that it doesn’t advertise itself as high-DPI? But KDE had no issues with it, we could install Ubuntu easily.

Why don't you just set the resolution manually temporarily for the installer to say 1920x1080 at boot time?

“Why don’t you just” is precisely the Linux thing that irks me the most.

Why don’t they just make it obvious? Why doesn’t the installer just figure it out or ask me when it launches?

I agree that that would help, but it was easier to just install another distro.

I mean it is probably a bug that may have been limited to your specific combination of hardware for all I know, not like they make sure it cannot work.
