I can't reach native 5120x1440

[monkeymachine]

I have a Samsung G9 and 2 hackintoshs. A Mac OS Catalina and a Mac OS Big Sur 11.4. I can only get 5120x1440 with Picture in Picture Mode. With 2 cables. Has anyone been able to get max native res with only one?

Thank you very much.

Did you manage to get this working?
