Selective monitor control
First Claim
1. A computer-implemented method for reducing energy usage by a monitor, the method comprising executing on a processing unit the steps of:
- distinguishing, from a remainder second plurality of blocks, a first plurality of blocks that are each within a top-focused active window within display information that is output by a main monitor board to a display area of a monitor, wherein the display area of the monitor is divided into a total display area grid of different blocks that includes the first plurality of blocks and the second plurality of blocks, wherein the remainder second plurality of the blocks are each within a remainder inactive and unselected area of the total display area of the monitor that is different from the top-focused active window;
selecting a first subset of the top-focused active window first plurality of blocks that is defined to include a focal point within the top-focused active window and at least one corner block located about and within at least one block from the focal point, wherein the first subset of the top-focused active window first plurality of blocks is distinguished from a remainder second subset of the first plurality of blocks of the top-focused active window;
driving the first subset of the first plurality of blocks of the top-focused active window display area of the display area of the monitor with display information at a normal level of color luminance and at a normal level of backlight power;
driving the second remainder subset of the first plurality of blocks of the top-focused active window display area of the monitor at the normal level of backlight power, and at a reduced level of color luminance that is lower than the normal level of color luminance; and
driving the remainder second plurality of the blocks within the remainder inactive and unselected area of the total display area of the monitor at the reduced level of color luminance, and at a reduced level of backlight power that is lower than the normal level of backlight power.

Abstract
Reducing energy usage by a monitor includes a map manager between a monitor interface and a processor that divides a display area of a monitor into areas and stores display information in a staging area. The map manager distinguishes an active window selected by a user from the remainder inactive, unselected areas of a display, and further determines a used subset of areas within the active window distinguished from the remainder unused areas as a function of a user preference. Accordingly, the map manager drives the monitor at each of the used area active window areas with the processor display information stored in the staging area at a normal luminance specified by the processor display information, and at each of the remainder unused, inactive and unselected areas of the total display area at a reduced luminance lower than the specified normal luminance.
