Abstract
A computer system and methodology for controlling the brightness of visual objects displayed on an electron beam flat panel display monitor used in a computer system having a multitasking operating system and a graphics controller coupled to the display monitor. The display control system includes an operating rules module, an activity monitoring module, and a palette manager module. The operating rules module identifies one or more predetermined conditions of operating system events; which require a variation in the brightness of selected visual objects pertaining to the predetermined conditions. The activity monitoring module monitors and filters the operating system events for the predetermined conditions and transmits instructions to a palette manager module to vary the brightness of the selected visual objects when a predetermined condition has been met. The palette manager module varies the brightness of the selected visual objects using the graphics controller.
