If you were wiring to display video on lcd panels throughout a home (say 2 to 4 screens), what wiring would you use? HDMI seems to be easiest and most cost effective because it's smaller wire (vs composite, dvi etc), best quality and includes audio and video. However, are there any encryption or other issues with using HDMI? The purpose would be to display anything from a computer, tv or security system. I'm aware that the system would require conversion and distribution boxes to bring everything into HDMI. Am I wrong to assume that would be best?
