When I heard about HDMI, I was like "huh.... @_@ what is that?" So, thanks to google, here's what I know about HDMI cables -> High-Definition Multimedia Interface (HDMI) is a licensable audio/video connector interface for transmitting uncompressed, encrypted digital streams. Sounds very canggih, right? I still am not very sure of the use of the cable but I think it is some cable tat connect the pc to some recording device (for music production, I guess)
