Unfortunately, not every NEC Multisync monitor handles 15 kHz. A couple of 
years ago I leeched the website to compile a list of 
possible models that seem to handle at least both 31 kHz VGA and 15 kHz. 
While the information does not necessarily have to be entirely correct, the 
NEC models on that list boiled down to MultiSync II, 3DS (!), 4PG, 6PGPLUS, 
XM29 (XM2950), XM37 (XM3750A) and XP37 (XP3778A). Sony also made a number of 
possible candidate monitors: CDP-1302, 1302A, 1303, 1402E, 9000, GVM-1310, 
1311Q, 2020, PVM-1351Q, 1354Q, 1390, 2030BS, 2530BS.

Of course there also are Commodore's "own" monitors such as 1940, 1942, 
1950, 1960 to consider. I found a reference that AOC CM-314 should be 
identical to the 1950. The list goes on with even more, obscure brands, but 
as I can't vouch for its accuracy it is mostly of academic interest, in 
particular as old CRT monitors now mostly live at the recycling station and 
those with dual or multisync abilities were uncommon already back in the old
