Multi-monitor system, and computer program and display device used in multi-monitor system

摘要

The purpose of the present invention is to provide a multi-monitor system comprising display devices among which individual differences are found in the luminance produced by the devices if each is given the same luminance setting value, wherein luminance matching between the display devices can be easily performed. According to the present invention, provided is a multi-monitor system comprising a plurality of display devices, wherein the system is characterized by being provided with a processing unit by which, on the basis of the luminance information values of a specific display device from among the plurality of display devices and the luminance information values of other display devices, and on the basis of a luminance setting value freely set by a user for the specific display device, the luminance setting values of the other display devices are calculated so that the luminance of the other display devices is effectively the same as the luminance of the specific display device.
