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

A method comprising:

• obtaining an overall media content, positional subsets of which is to be played out corresponding displays of a plurality of displays arranged in one or more adjacent vertical columns;
• playing out, with a corresponding media player of a plurality of media players, a corresponding positional subset of the overall media content, at a full resolution of the media content, to the corresponding display arranged in the one or more adjacent vertical columns, with a corresponding delay to compensate for scan out lag associated with the media content, wherein the corresponding delay is based on a frame refresh rate of the media content and a vertical position number of the corresponding display in the one or more adjacent vertical columns from top to bottom, wherein at least a first media player of the plurality of media players is coupled to each other media player of the plurality of media players, and wherein each media player includes a clock, the clock of a first media player of the plurality of media players serving as a master clock;
• and
• slaving the clocks for the plurality of media players using the master clock such that the clocks of the plurality of media players are synchronized to the master clock.

A system comprising:

• a plurality of media players, each media player of the plurality of media players configured to be coupled to a corresponding display of a plurality of displays and configured to play out a corresponding positional subset of an overall media content at a full resolution of the media content and such that collectively the plurality of displays display the overall media content as a single display;
• and
• wherein each of the plurality of media players is configured to play out the corresponding positional subset of the media content, with a corresponding delay, to the corresponding display arranged in one or more adjacent vertical columns, to compensate for scan out lag associated with the media content, wherein the corresponding delay is based on a frame refresh rate of the media content and a vertical position number of the corresponding display in the one or more adjacent vertical columns from top to bottom;
• wherein at least a first media player of the plurality of media players is coupled to each other media player of the plurality of media players, wherein each media player includes a clock, and wherein the clock of a first media player of the plurality of media players serves as a master clock that slaves the clocks for the plurality of media players such that the clocks of the plurality of media players are synchronized to the master clock.
