Not related to monitors, but this is how I bricked my old Lenovo Thinkpad W520 4 times. I switched between the Intel and Nvidia GPUs via the BIOS setting enough times to wear out the BIOS chip. I didn't figure out what was going on until my 3rd replacement.

Attempting to switch GPUs from userland, or?

They said "via the BIOS setting", which is definitely not userland switching.
