Display system, display controller and computer program

Abstract

Provided is a display system which can save power consumption by switching a plurality of monitors to the operating state of low power consumption when a user utilizing multi-monitor environment stops the work for a short time, and also provided is a display controller and a computer program constituting the display system. A human sensor (3) is mounted on at least one of monitors (2a-2c) in multi-monitor environment where a plurality of monitors (2a-2c) are connected with a PC (1), and the PC (1) controls switching of the operating state of a plurality of monitors (2a-2c) according to the detection results of the human sensor (3). The monitors (2a-2c) are operated in sleep mode or power off mode when all human sensors (3) detect absence of the user, and the monitors (2a-2c) are operated in normal operation mode when at least one human sensor (3) detects presence of the user.
