A display device and a display system are provided to display an image on a sub display device even when a mode of a main display device is changed, thereby improving a viewer's watching environment. A demodulator(20) demodulates a broadcast channel selected through tuners(10,11). A demultiplexer(30) demultiplexes a signal demodulated by the demodulator. An image signal processor(40) controls so that the demultiplexed signal is outputted. A display unit displays a video signal outputted from the image signal processor. A controller controls so that the broadcast channel is transmitted through a scart terminal. A switching unit switches connection of source devices that provide video signals. The controller monitors whether the video signals are transmitted through the scart terminal. |
