According to the October '89 issue of MacUser, in their review of grey-scale
monitors, the Apple Hi-resolution Monochrome monitor is 76 dpi, the
Apple Portrait Display is 80 dpi and the Apple Two-Page Monochrome monitor
is 77 dpi.  Thus, NONE of the Apple grey-scale monitors display images
at "actual" size.

BTW, I wonder why Apple downplays their monitors by calling them
"monochrome" when they're all capable of at least 16 shades of grey
and the Hi-res "monochrome" monitor can display 256 shades of grey
with Apple's card.

And while I'm at it, does anyone know if the built-in video on the
IIci can drive all of the Apple color and grey-scale monitors, and
if so, are the 1- and 2- page monitors still limited to 16 shades
of grey?  Are there any non-Apple monitors that the built-in video
can handle?

Thanks,
