It is highly important to make sure the different channels displaying the scene simultaneously and promote the performance of the scene to display. Taking a multi-tiled display system (MTDS) as an example, the system architecture was studied, and a message control synchronization method was proposed which was capable of solving the non-synchronization problem of the MTDS, and a circular buffer solution was described which overcame the problem of lost packages under the circumstances of high frequency in reading or writing. Experimental results show that the solution solves the non-synchronization problem of the multi-tiled display system. Key words: multi-tiled display; display synchronization; message control synchronization method; circular buffer 1 ServerMaster/Slave[7] Message Control Synchronizatio
