DISPLAY DEVICE, MULTI-DISPLAY SYSTEM AND MULTI-DISPLAY METHOD

摘要

A display device (and method) includes a receiving unit that receives a video signal output from a superordinate device. A display unit displays at least part of the image according to the video signal. A storage unit-stores the resolution of the image to be displayed on the display unit. A connector can be connected to a subordinate display device. A communication unit, when a subordinate display is connected to the connector, receives a second resolution as the resolution notified by the subordinate display device and outputs the video signal to the subordinate display device. A control unit provides notification to the superordinate device of a third resolution according to the first and second resolutions, the first resolution being a resolution of the display unit and being a resolution of an image to be displayed on the display unit, the resolution of the image being previously stored in the storage unit.
