Yes, there will be overlap. If I were to split the screen and fill the top half with color 1 and the bottom half with color 15 (ala Videosoft "Color Bar Generator"), I'd get something that looks like this: (where each "*" represents a dot that is the same exact color of yellow) (and exaggerating the horizontal spacing between pixels to show the phase shift....it's quite visible on a real display) * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * -Chris On Wed, 13 Jul 2005, C.
