Change resolution of the logon screen

Hello everyone. I am currently getting over from Windows to Linux. I choose to dual boot Windows 11 with Debian and KDE as my desktop. The machine I am using is a Lenovo laptop with resolution of 3072x1920. For Grub I already changed the resolution to 1920x1200 to be able to see what is on the screen. However, after selecting Debian I am confronted with the logon screen in the highest possible resolution, e.g 3072x1920. I have been searching the whole day now to see if I can change the resolution of the logon screen to 1920x1200 so I can see whats on there. So far, I have had no success. Is it possible to change the resolution of the logon screen and if yes, how.

Thanks for any help
