    PC monitor is used to detect signal information.\n

    PC monitor is used to detect signal information such as
    - input source type : Component / HDMI / DVI / VGA
    - input horizontal frequency
    - input vertical frequency
    - input vertical total
    - input sync detection : H/V polarity, scan type
    - HDMI/DVI only : Data Enable section detection result
    - Euro HDTV detection result
    and the sync stable result will be passed back and make sure these signal characteristics are steady.

    TO BE NOTICED :
    signal characteristics being steady does not mean that this signal are valid signal.
