software running on a host computer, for a user to input size of each screen of a video wall, to calculate a delay time for each row of screens of the video wall; and
a video wall control device, coupling the host computer to the screens,
wherein:
the video wall control device outputs a plurality of split videos to the different screens through separated output ports, and drives each row of screens to display according to the delay time calculated for the row of screens, wherein the screens of the same row correspond to the same delay time; and
based on a first vertical screen resolution of a first row of screens, the software running on the host computer calculates a delay time of a second row of screens adjacent to the bottom of the first row of screens.
