The card can only display as many colors as there are pixels on the screen.
As an exercise, here's some basic calculations:

    With 24 bit color, there are 2^24 (16.7 million) colors that can be
    displayed.  For a monitor to display all of these colors, it would need
    to have resolution of 2^12 by 2^12 (assuming for simplicity that the
    monitor is square), which is 4096 by 4096 pixels.

    Now with the "standard" 72 dots per inch, this monitor would have to
    be 56.9 inches by 56.9 inches, or almost five feet square.

    Although it would be nice to have a monitor the size of a drafting
    table, I don't think we will see one soon.

On an unrelated note, I am selling my Mac SE.  It is in perfect condition.
It has a 20MB internal hard drive, one internal 800K floppy drive, 1MB of
memory, and a standard keyboard (and a mouse, of course).  I will also
throw in a copy of Microsoft Works 2.0 and pay shipping and insurance fees
(up to a maximum of $50).  I would like $1700 for it.  Send me mail at any
of the following addresses if you are interested, or call (317) 285-3614 at
any time.
