This 2m DisplayPort to HDMI Cable (male to male) is fully featured with all the bells and whistles, so the only limition to what you get get out of your system is the system itself! By that, I mean that this cable is fully audio combatible for 7.1 HD audio and HD 1080p video simultaneously, but not all DisplayPort enabled equipment sends those signals through the DisplayPort socket. HDCP 1.2 and DPCP are accounted for, so you needn't worry about displaying protected content. It's the no-fuss solution for using HDMI screens on DisplayPort outputs!
Please note this passive cable requires compatible DisplayPort/HDMI equipment, so be sure to check for the D++ symbol on your source device and read the manual to check you're getting sound output if you're expecting a complete HDMI conversion. This cable is not bi-directional, and does not convert HDMI to DisplayPort.
DisplayPort Compatibility Note
DisplayPort (DP) cables and adapters are not bi-directional, and require a DP output which is DP++ (Dual Mode) compatible. When a DisplayPort to HDMI adapter/cable is connected to a DP++ (Dual-Mode) output, the output device senses the presence of the adaptor/cable and sends HDMI signals over the DisplayPort connector rather than DisplayPort signals. No signal conversion is performed by the adapter/cable. HDMI signals are merely passed through.
