Abstract
A display controller system is controlled to provide a display surface zoom using hardware scaling from user input at the operating system, application program or hardware level. User input defining coordinates of a frame portion within a frame buffer memory is obtained, and a resolution of the zoom display device is determined. An aspect ratio of the zoom portion defined by the user input is adjusted to correspond to the zoom display device resolution. The display controller system is programmed to implement the display surface zoom to provide a full screen view of the zoom portion on the zoom display device. In the display controller system, the zoom portion of the frame buffer memory is scaled, converted into a display signal and output.
