*4  HDMI® (Deep Color) with HDCP What is HDCP/HDCP technology? HDCP is an acronym for High-bandwidth Digital Content Protection. High bandwidth Digital Content Protec-tion (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 HDMI input, this does not necessarily mean the projector is not functioning properly. With the implementation of HDCP, there may be cases in which certain content is pro-tected with HDCP and might not be displayed due to the decision/intention of the HDCP community (Digital Content Protection, LLC).*5  An image with any resolution will be displayed with scaling technology.
