Abstract
The invention is generally directed to methods and apparatus for preventing image tearing where a single video input is streamed to two or more independent display devices for simultaneous display. A preferred method includes: (a) receiving a sequence of frames from an image data source for refreshing a first display device and at least a second display device; (b) storing a first, sequential frame in the sequence in a first buffer; (c) storing a second, sequential frame in the sequence in a second buffer; (d) refreshing the first display device from the first buffer; (e) refreshing the second display device from the first buffer; (f) determining whether the steps (d) and (e) of refreshing the first and second display devices are complete; and (g) storing a third, sequential frame in the sequence in the first buffer, provided the steps (d) and (e) of refreshing are complete.
