Most of us will interpret this as "lower frequency" vertical
nad horizontal scanning rates, just in case that's not what was meant.
Most, if not all, modern (post ~1975) computer monitors (not counting
LCDs) use magnetic deflection, like your TV. The deflection coils
also behave as incudtors, and their impeadance is lower at lower
frequencies. Lower impeadance can lead to higher currents from common
drive circuits, which can toast them.

Actually, lower scanning rates, for a given dot clock, increase
the resolution. There is time for more dots in the longer scan period.
(Lower frequency gives longer periods.)
