Sub-frame synchronization of multiple displays with independent vertical refresh rates

Abstract:

Presented herein are techniques to retain full resolution across all screens of a video wall and achieve perfect visual synchronization (sync), such that all screens in a video wall configuration act and look like a single screen. In one form, a system is provided that includes a plurality of displays being arranged in one or more adjacent vertical columns, and a plurality of media players. Each media player of the plurality of media players is coupled to a corresponding display of the plurality of displays and is configured to play out a corresponding positional subset of an overall media content, with a corresponding delay, to the corresponding display arranged in the one or more adjacent vertical columns to compensate for scan out lag associated with the media content.
