Mary Lou indicated 205 ppi in b&w vs 120 ppi in color. This is entirely consistent with square pixels of 3 colors, since (205*205)/(120*120) ~= 3. There is apparently some color in the black and white mode, and this might indicate that the screen isn't actually being driven at 205 ppi. As pdurrant indicated, the effective resolution of the color mode may be higher than 120 ppi anyway.
