Because you see color, technically you do not have a bad "pixel" you have a bad sub-pixel. Three sub pixels, one red, one green and one blue make up a "pixel". BTW I assume your display is 1024 x 768 based on the 786432 number. To get the total sub-pixels on your LCD you need to times this number by three. If it makes you feel any better, your LCD at 1024 x 768 has one bad sub-pixel out of a total of 2,359,296 sub-pixels.
