A detector for detecting multiple HDMI signals includes an HDMI source port, an HDMI objective port and a status detecting unit. The HDMI source port includes a CEC pin, an HTPLG pin and a DDC pin. The HDMI objective port includes a CEC pin, an HTPLG pin and a DDC pin set. The status detecting unit includes an input port, an output port and a status crosscheck module. The input port includes a CEC pin, an HTPLG pin and a DDC pin set respectively connected to those of the HDMI source port. The output port includes a CEC pin, an HTPLG pin and a DDC pin set respectively connected to those of the HDMI objective port. The status crosscheck module detects whether the HTPLG pin and the CEC pin of the input port receive signals or not.
