All modern PC monitors are smart enough to display "signal out-of-range"
messages on the screen. It is the older fixed-sync and analog-multisync
monitors that had problems with smoking and burning up.

When it comes to warnings about that kind of problem, the doc writer is
better safe than sorry, but for the rest of us it's more like ancient
superstition.

Unless you've got an old IBM XT with a "digital RGB" CGA monitor, that is...
