Before analog monitors got a builtin delay for changing the video mode, you could intentionally wreck the device by writing a few lines of code in QBasic, and by the time someone had already power cycled the poor machine while troubleshooting, the evidence was long gone.

I'm not sure if its a good idea, but I'm going to link another of my old timer stories here:

Analog monitors didn't get delay for the protection. It's been a side effect of auto-sync feature when monitor spends some time analyzing input sync signals to automatically adjust its timings.
