You need a 25khz monitor.   Here's a 
list I've compiled over the years.

25khz 640x400 SOG monitors

HP 98204A (used with 82913A 12" 640x240 
and 82912A 9" 640x240 monitors)
HP 98204B (used with 35721 14" 640x400 
and 35731 12" 640x400 monitors)
HP 98543A (used with 35741 12" 640x400 
RGB monitor)

CRT
- Hitachi CM1587
- Hitachi CM1711

LCD
- NEC LCD1510+ (not tested)

- NEC LCD1810 (LA-1831JMW-1)
   Mac + PC -- fair performance, poor 
scaling.
   HP 300/98543 -- works, but banded 
background cannot be completely
      faded to black (I got rid of my 
1810's for this reason).

- Viewsonic Vp150
   HP300/98543 -- works well, great 
background, colors only fair.

- Viewsonic VP181
   HP 300/98543 -- not perfect but can 
be adjusted ok.
     banded background *can* be faded to 
black.
