Abstract

A computer display apparatus includes first and second display units operatively coupled to a display controller. The display controller receives imaging instructions for images and display mode instructions for displaying the images, and causes the display units to independently generate images from the imaging instructions according to the display mode instructions. The display controller may include a display processor programmed to generate pixel data according to the imaging instructions, and first and second refresh outputs programmed to independently generate image displays from the manipulated pixel data on the first and second display units in first and second display modes, respectively. A display re-mapper may manipulate the pixel data according to display mode instructions. A display memory fetcher may manipulate pixel data according to display mode instructions in response to a request for pixel data from the first and second refresh outputs independently.
