Which monitors? I've not heard of this sort of thing happening for at
least 15 years, and even then it was a bit debatable. Even only
relatively modern monitors just quietly display a "no sync" message or
blink an LED when the sync frequencies are out of range - which are
generally pretty wide anyway, these days.
It's pretty trivial for a manufacturer to construct a monitor which
ignores out-of-range incoming signals, and most do.

Because it's completely meaningless techno-babble.
Just ignore it; there's no black magic involved with horizontal & vertical
scan frequencies, a sync signal, and red, green & blue video inputs.
It really doesn't make any difference if the software producing the
signals is "memory intensive" or "positively pedestrian".
