Patent ID: 8384707

Claim:
A method for synchronizing the display of images on a plurality of display devices, comprising: generating a first signal representing first image data to be displayed on a first display; generating a second signal representing second image data to be displayed on a second display; generating at a first signal generator a master sync signal; receiving at a second signal generator the master sync signal; generating at the second signal generator a video clock signal based on the received master sync signal, wherein the video clock signal provides a timing information for one of display of the first image data on the first display or display of the second image data on the second display; programming a convergence time which determines a quantity of pixel pulses by which to adjust the video dock signal to establish a synchronization between the video clock signal and the master sync signal, wherein the quantity of pixel pulses is selected based on a degree of synchronization between the video clock signal and the master sync signal; adjusting the video clock signal based on the convergence time; determining if the video clock signal is not synchronized with the master sync signal; and in response to determining that the video clock signal is not synchronized with the master sync signal, reprogramming the convergence time using a new quantity of pixel pulses based on a degree of synchronization between the adjusted video clock signal and the master sync signal.
