Cost of display scanout in terms of power? When nothing's moving, more pixels = higher bandwidth requirements, and the thing has to be clocked higher. (I guess it runs constantly. The new non-scanned LCDs will help I suppose.) You also need more RAM, and that needs refreshing. And any time anything is moving, there's 4x as many bytes being shuffled about, and they have to be shuffled about 4x as quickly, because the display area is the same.
