Abstract
Controlling electrical power consumption of a display monitor screen involves grouping screen pixels into different resolution cells, detecting display of one or more windows on the screen, and selectively controlling the cells by providing power only to the pixels in cells corresponding to one or more windows of interest to the user, and reducing power to pixels in remaining cells.
