Abstract
A video wall, having screens, cables, synchronization detection modules and a central control unit. The cables are operative to carry image data to be displayed on the screens. The synchronization detection modules are coupled between the screens and the cables for detection of a feature symbol. The central control unit collects detection results from the synchronization detection modules, and the detection results are utilized in the adjustment of the image data before cable transmission. In this manner, image display synchronization between the screens is achieved. The synchronization detection modules may be implemented as connectors, each having a first end connected to a screen and a second end connected to a cable.
