Don't forget the color depth. If you go to 8- or 16-bit color rather

can then get the 1152x864 size, but not as many colors. Here is the
video RAM needed for an 1152x864 display:
24-bit: 24MB
16-bit: 15MB
8-bit: 7.5MB
If all you can give is 8MB, you're limited to an 8-bit 1152x864 display
(256 colors). The formula is:
video RAM needed (in MB) = (width x height x number-of-bits)/1048576
Your formula is calculating the amount of memory in Mega _bits_ not Mega
_Bytes_. You have to divide the number by 8. So you get
video RAM needed (in MB) = (width x height x number-of-bits) / 8388608
Doh! Right. My boo-boo. Gotta stop writing messages to the list with
people in my office yelling at me.
