Abstract:
A video display apparatus functions as a master which is to be connected in loop to other video display apparatus(s) functioning as slave(s) in order to configure a multi-display apparatus. The master video display apparatus includes an extracting unit configured to extract first characteristic data from a received video signal, a controller configured to generate a common video setting value and control a light source of an own apparatus based on the generated common video setting value, an input unit configured to input second characteristic data from the upstream apparatus, and a output unit configured to output the first characteristic data or the common video setting value to the downstream apparatus. The controller outputs the extracted first characteristic data to the downstream apparatus, calculates the common video setting value based on the input second characteristic data, and outputs the calculated common video setting value to the downstream apparatus.
