   I knew the NEC Multisync 1 and 2 work (they're listed as such in
the comp.sys.apple2 FAQ) and which is why I said "pretty much all
modern" in reference to monitors. Your average cheapo monitor (or even
a number of 'multisync' ones like my MAG MAX17F (repaired twice,
replaced twice. I'm not gonna buy another) can't hit 15Khz. 

   When things may or may not work, I give lots of details (like
15Khz) so that people who want to check out if a monitor will work can
pull out the manual and check for themselves. [This is why I like
hardware to reliable: if it says it works, it should work 100% of the
time.]
