High bandwidth Digital Content Protection (HDCP)is a system for preventing illegal copying of video data sent over a Digital Visual Interface (DVI).If you are unable to view material via the DVI input, this does not necessarily mean the projector is not functioningproperly. With the implementation of HDCP, there may be cases in which certain content is protected with HDCP andmight not be displayed due to the decision/intention of the HDCP community (Digital Content Protection, LLC).
