Different resolutions on login screen on 4K monitor using OpenCore

Hi, first I want to report that I have read here some posts about the issue but they don't give me the solution, I have also tried with UIScale parameters, deleting com.apple.windowserver.plist, etc. I'm using OpenCore running macOS Ventura with a 4K monitor (DisplayPort connection) and the login screen is displayed at 1920x1080 (HiDPI), while my desktop I have it set to 2560x1440 (HiDPI).

I just updated Ventura to version 10.6.9 and when logging in right after it showed the resolution fine (2560x1440 (HiDPI)), but when restarting again it shows at 1920x1080 (HiDPI).

I have tried with all versions of macOS and the problem is still present.

I don't know if the problem comes from OpenCore or from the operating system.

Has anyone been able to find the real solution? To know what is going on to understand why the resolution is different from the desktop.
