CGA is, I think, strictly speaking 262 lines 60fps, making its timings compatible with NTSC.

To neon_indicator: the multisync monitors we're discussing here are the type which do sync down to 15kHz. They were very popular about 20 years ago as some machines (especially the Amiga and Archimedes) made the transition from TV-type outputs to higher resolutions. NEC and Eizo were the big names I remember. Some time in the mid 90s the term 'multisync' ceased to mean the ability to sync down to TV rates and, as you say, around 30kHz became the minimum line frequency for such monitors.
