DISPLAY DEVICE AND DISPLAY METHOD

摘要

A display device includes: a first detection unit that detects an external signal from a second external device via a second connection unit, and outputs a first detection result indicating presence of an external signal; and a control unit that determines whether the second external device is connected with a second input unit based on the first detection result, and performs control so that a video signal to be supplied to a display unit is switched from a first video signal to a second video signal to cause the display unit to display an image based on the second video signal in a case where the control unit that determines that the second external device is connected with the second input unit.

1. A display device comprising:
a plurality of input units that include a first input unit that is connected with a first external device and receives a first video signal from the first external device and a second input unit that is connected with a second external device and receives a second video signal from the second external device; a plurality of connection units that include a first connection unit that is connected with the first external device and a second connection unit that is connected with the second external device; a first detection unit that detects an external signal from the second external device via the second connection unit, the external signal being different from the second video signal, the first detection unit outputting a first detection result indicating presence of the external signal; and a control unit that determines whether the second external device is connected with the second input unit based on the first detection result, the control unit performing control so that a video signal to be supplied to a display unit is switched from the first video signal to the second video signal to cause the display unit to display an image based on the second video signal in a case where the control unit that determines that the second external device is connected with the second input unit.
