The Macintosh LC's built-in video supports a maximum video depth
determined by two variables:
- The size of the monitor connected to the Macintosh LC, and
- The amount of video RAM installed in the Macintosh LC.
If the Macintosh LC has 256K of video RAM installed, then the bit depth
for the Macintosh 12-inch RGB display will be 8 bits per pixel, and for
the 13-inch High Resolution RGB Monitor, the depth will be 4 bits per
pixel.
If the Macintosh LC has 512K of video RAM installed, then the bit depth
for the Macintosh 12-inch RGB display will be 16 bits per pixel, and for
the 13-inch High Resolution RGB Monitor, the depth will be 8 bits per
pixel.
Four bits per pixel will give you 16 colors or shades of gray on the
screen at one time. Eight bits will give you 256 colors or shades of
gray. Sixteen bits will give you thousands of colors.
It's possible to achieve 24 bits per pixel on the Macintosh LC through
third-party Macintosh LC PDS video cards.
