Abstract
Systems and methods for repositioning and displaying objects in multiple monitor environments are disclosed. When two or more of the monitors have different color characteristics, images moved between monitors are processed to take advantage of the particular color characteristics of the monitors, while reducing the processing resources that might otherwise be needed to entirely render the image from scratch. For instance, an image positioned within a first monitor space can be repositioned such that a first portion is displayed in the first monitor space and a second portion in the second monitor space. The data representing the first portion of the image is moved from a first location to a second location in a frame buffer in a bit block transfer operation. If the first and second monitors have the same color characteristics, the data representing a second portion is also transferred using a bit block operation. However, if the color characteristics are different, the data representing the second portion of the image is passed through a display engine that adapts the data to the particular color characteristics of the second monitor. Furthermore, cursor image movement operations …
