This is the 2020s equivalent of setting the display resolution beyond what your monitor could handle back in the Win2k days. Back then it did not revert the settings back after 20 seconds!
Yet, things could be worse. Back in the 80s & 90s it was possible to select a resolution/refresh frequency that would permanently damage (e.g. destroy) a CRT (cathode ray tube) monitor.
That reminds me of setting unsupported display resolution back in the mid 90s on Windows 95, resulted in blank screen. Luckily my brother and I knew the UI by heart, rebooted the machine -> opened "Start" menu -> Settings -> Control Panel -> Display -> Move to Settings tab -> Change to working resolution -> Apply -> Reboot - all on the blank screen using keyboard, it worked though!
