Abstract: A method for sending commands to display devices connected in series includes sending a command to the first display device of N display devices connected in series. The command has a header and each of the N display devices has a same preset identification code. The first display device of N display devices receives the command and determines whether the header is corresponding to the preset identification code. When the header of the command is corresponding to the preset identification code, the first display device executes the command. When header of the command is different from the preset identification code, the first display device generates a modified command by adding an adjustment to the header of the command and sends the modified command to the next display device.
