1024 * 1280 = 1310720 pixels.

16 million colours comes from the fact that each pixel has 24 bits of information to store the colour , and 2^24 = 16777216 possible values for the colour.

24 bits = 3 bytes.
since 1 byte=8 bits
Multiplying 1310720 by 3 gives 3932160 bytes. This is approximately 4 MB of video memory.
