'Specially with an LCD monitor. I used to have six or seven resolutions,
from 1536x1152 down to ?240x180?, set up in X so I could ctrl-alt-[+-]
through them. (Faster to do switch res than do whatever to magnify
something, and it doesn't affect the apps at all.) But this monitor's specs
are tighter than my last one's, and LCD monitors don't look so good at
non-native resolutions, so now I have only three resolutions defined, all
small-integer-ratio divisors of the native one.

Eh, some people don't perceive flicker. I used to run the aforementioned
CRT at 59.x Hz. Drove my dad crazy. As long as I kept my desktop
reasonably dark, it was OK. Lower res => lower dotclock => less heat from
vid card. IIRC, heat (and power use) is proportional to clock rate squared,
which means it's proportional to refresh rate squared.

Ignorance is bliss. At least in some cases.
