All my magazines are at home.  From memory:

The monitor has four levels of gray, for an effective resolution of
2400x3328, which is just about right for an 8x11 300dpi laser printer
image.  Although I have not seen it personally (yet), I've heard the
quality is excellent (which if it is like any other PGS products I've
worked with, does not need to be said).

Sigma Designs, a California based company, makes a graphics card to drive
this monitor, with 4 levels of gray.  A package price for the card and a
15" monitor is (from memory) $1800, with a 19", $2200.  Card alone: $1200.
[Again:  all prices from memory].  These are "dumb" cards, they simply
memory map parts of the screen, and don't draw primatives (lines, boxes...).

I came >< close to buying one of these packages, but haven't (yet), as I'm
waiting for a desktop cray with 4000x8000x64 planes for < $1000 :-) !

I'm sure there are preview packages out which run on these cards.  We all
know that manufacturers are glad to help with this type of information.

I shouldn't have to say this, but ... I have no connection with either
company except as a satisfied customer.
