First of all, thank you for your help. My Raspberry Pi 3B+ keeps failing when running the tty2rpi script. At the same time, I don't have permission to modify files under the boot directory, such as config.

I have a Raspberry Pi 3B+ and an 14 inch ultra-wide screen monitor with a resolution of 38401100, but the Raspberry Pi can only display 19201080 and cannot adapt to the aspect ratio.
