BIOS or UEFI settings not working

Upgrade to 19.3 MATE from 19.2 went smooth but the drivers for the NVIDIA GP106 does not work when booting from the normal Grub menu (the result ion is set really low). In the driver mgr the Nvidia-driver-435 is recommended and is also chosen, but when the system starts the resolution is really low and in the monitor preferences the monitor cannot be identified. I have noticed that if I restart and choose system settings instead of the Mint version 19.3 in the boot menu the system stops, restarts, and a question is raised if I want to modify the system settings (BIOS?). One option here is to continue, and if I choose that all is well. So I need to enter system settings and confirm continue and all works. What is wrong here?
