|All you had to do was google the terms & read your manual. It's also mentioned in that article: "When using a HDMI adapter (included as well), you will also have access to HDMI+HDCP+Audio, which allows easy setup of a media PC. AMD has integrated a Realtek 7.1 audio device inside the GPU which means that the sound card's HDMI output shows up as sound device in Windows."|
HDMI = High-Definition Multimedia Interface. It's used to transmit both the video/audio (digital) to an external device thru a single cable (HDMI cable).
HDCP = High-bandwidth Digital Content Protection. It's a form of copy protection.
The "HDMI+HDCP+Audio" is used more for a Home Theater setup than for a gaming system...unless you have an HDMI capable monitor or TV? It's probably useless to you unless you have your PC connected to a TV & the TV has an HDMI port, in which case you would need an HDMI cable.
