Hi. I've still not tested the Raspberry PI's guide for creating a kiosk, so I can't tell you how to fix the monitor problem. However, there's a few fix you can use to prevent the user from forcing to exit from the kiosk mode.
Generally, there're 2 possible reasons for a kiosk to exit from this mode:
The second can be prevented by clearing the keyboard section in your "/etc/xdg/openbox/lxde-pi-rc.xml" file, while the second can be prevented by intercepting the Chromium hotkeys at the system level and assigning them a new function, as the OS hotkeys have priority compared to those of Chromium.
I've arranged a tutorial a few years ago about this topic: https://peppe8o.com/raspberry-pi-kiosk- ... ive-stand/, you can try if this fixes some of your issues.
