One note, because some people quoted, as the requirement
for alternate monitors:

1120x832 pixels, 68Hz non-interlaced frame rate.

Well, those numbers are not the critical numbers.
If you look for monitors in the market citing the above numbers,
I will guarantee you that you will not find any monitor which
matches those numbers.
The key number is 64kHz horizontal scan rate.
Ignore what the pixel resolution says.

SONY GDM-1601, which NeXT has been using currently, is specified
as 1280x1024 pixels 60Hz non-interlaced, if you look at the
spec sheet from SONY.
