Abstract
A method and apparatus for controlling brightness, color and contrast in CRT monitors used in information handling systems. In accordance with the present invention, a viewing area on a CRT monitor is enhanced by applying appropriate signals directly to the grids in the CRT. In one embodiment of the present invention, appropriate voltage signals are applied to the Ggrid of the CRT. Parameter data is provided to the CRT using a DDC2/CI data channel, with the parameter data being based on the VESA MCCS command set. Utilizing the method and apparatus of the present invention, it is possible to achieve significantly greater brightness, color and contrast control in enhanced viewing areas displayed on a CRT monitor used in an information handling system.
