TTL Monochrome monitors are usually set up to match PC Monochrome scan rates.
You may be able to adjust the monitor either external or internally or may
have to change some component values.

CGA Monitors use normal scan rates and work fine, what they describe sounds
reasonable.  You can also use a Monochrome composite monitor to good effect,
these used to be sold as Apple II Monochrome monitors or as Monochrome
monitors to be used with CGA adapters to get monochrome graphics.

Make sure whatever monitor you get does have a long persistance phospher -
those intended for MDA use will, others might...
