- the amount of vram needed for different pixel depths is listed in the
- manual
- as i recall, the name of the book is "Getting Started"
- it's the one that is wirebound
-
- the formula for bit depth / memory should be:
- k = (vertical resultion) * (horizontal resolution) * (bit depth) / 3072
- or
- so a 13" monitor needs
- k = 100 * (bit depth)
- depth colours memory
- 1 b+w 100 k
- 2 4 200 k
- 4 16 400 k
- 8 256 800 k
- 16 65536 1.6 m
- 24 166777216 2.4 m
