Abstract

System and method for selectively updating a display in a multiple display device system. Software executing on the computer system analyzes information associated with the display devices, e.g., respective levels of user activity (e.g., peripheral activity), graphics activity (e.g., changes in image data), and/or application activity, associated with each display device, optionally generating priority information associated with the display devices. The display devices are updated in accordance with the analysis using two or more update rates, optionally based on the priority information, e.g., by generating a sequence of video frames based on the analysis, each video frame including a video image and frame identifier designating a display device, and transmitting the sequence over the cable to a plurality of frame grabbers, each frame grabber examining the sequence of video frames, selecting a video frame based on the frame identifier, and forwarding the video frame to the designated display device.
