A user can use an HDMI cable to directly connect an Apple TV to any monitor with an HDMI port. As of July 2012, OS X Mountain Lion permits wireless mirroring of a Mac, iPhone, iPad or iPod Touch to any Apple TV. The monitor must be HDCP ready to support the connection. HDCP or High-bandwidth Digital Content Protection is a form of digital copy protection developed by Intel Corporation designed to prevent copying of digital audio and video content as data travels across connections. Connections used include DisplayPort (DP), Digital Visual Interface (DVI), and High-Definition Multimedia Interface (HDMI), as well as less popular, or now defunct, protocols like Gigabit Video Interface (GVIF), and Unified Display Interface (UDI).
HDCP is commonly incorrectly called High-Definition Copyright Protection.
