I connect to a headless Pi from my Mac. I've set resolution in raspi-config, I've manually edited /boot/config.txt, and when I select Screen Configuration at the desktop (VNC'd in from the Mac) nothing happens. I've done this all in the past, but the new lack of a screen resolution menu item means whatever I used to do no longer works. I'm sure this is a well-known issue, but I can't find any reference to it here.
64-bit Raspberry Pi OS, newly installed. Booting from SATA SSD. I installed Real VNC Server to connect (which I have to manually launch every time I reboot even after setting it up to autoload which is another irritation I need to deal with after I can get more than a postage-stamp-sized screen to work in.)
