Ooh, I know this one! Here's what I did to get it working and set so it survives a reboot:

1. In a terminal, run sudo arandr
2. Set all of the monitors to 1080p
3. Close arandr
4. Go to Settings > Display
5. Rearrange monitors in correct order if necessary
6. Set the each monitor to the correct resolution and frequency, applying the settings after each update
7. All monitors should now work, BUT they will not survive a reboot in Pop-OS 22, because the GDM3 login screen will NOT have this information, and will reset everything. So we must copy the pop-os monitors.xml file to the gdm3 config directory:

sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config/

Note: You may need to do this as sudo -i

8. Reboot, and all 3 monitors should be loaded in the correct positions, at the correct resolution at the login screen

Not 100% sure, but I think your desktop environment is usually responsible for maintaining monitor configuration. I don't use pop os, but maybe look for errors saving config to your home directory or something???

*Dual boot (a duel is with weapons)

Are you on x11? Wayland oftens handles multi-monitor setups more gracefully. If wayland fixes it and you need x11, you would at least know where to start troubleshooting.
