Hexagonal packing is a more "natural" packing pattern than square packing. Are there any reasons beyond the obvious that modern display screens use the latter?
For example, the rasterization of a horizontal or vertical line on a square-packed display is trivial, but on a hexagonally-packed display, the rasterization of at least one of them is not. But what about an arbitrary line? My intuition tells me that an arbitrary line would have a "better" rasterization on a hexagonally-packed display. Would this carry over to an arbitrary image? Would photos look better with hexagonal pixels than they would with square ones?
