Chip and related electronic device

A chip comprising:

• at least one input interface receiving at least one input source;
• an output interface comprising a V-by-One (VB1) interface, wherein the VB1 interface is divided into a first VB1 output terminal and a second VB1 output terminal;
• and
• a data processing module, comprising circuitry, coupled to the at least one input interface and the output interface and configured to process input data from the at least one input source to obtain the same or different content,
• wherein the first VB1 output terminal and the second VB1 output terminal output the same or different content, thereby performing a function of a co-display or a different display;
• wherein the VB1 interface comprises a preset number of data lanes, in response to the VB1 interface being divided into the first VB1 output and the second VB1 output, the first VB1 output occupies a first number of data lanes, and a second number of the second VB1 output occupies data lanes, the first number is equal to or less than the second number, and the sum of the first number and the second number is equal to the preset number.
