When a second receiving card is inserted in the insertion slot, the detection device outputs a high-impedance signal to the second receiving card to enable the second receiving card to generate an enabling output, generates a second data output with reference to the enabling output and the image signal outputted by the second receiving card, and transmits the second data output to the display panel.
