Just installed Focal selecting the option to install 3rd-party drivers during setup process, and after the first boot screen resolution is 800x600. I verified the detected version of NVIDIA driver and I realized it was 440, although correct version is 390. Finally I manually installed proper version (390) and now the graphics are working OK.
