HDCP: Does it go both ways? (1 Viewer)

[Kelly N]

I know that if you have a display with a DVI input with HDCP that your source must also incorporate HDCP. What I need to know is if I have a source that incorporates HDCP like the LG LST-3510A does my display HAVE to incorporate HDCP or does it just make the tuner/DVD player compatible with more displays? I want to mate it with an Infocus LP350 and I can't find any mention of HDCP on the company's website.

As I understand it, if the display has HDCP then the source feeding it CAN have it or not and it still should work. If a material source, such as a DVD (usually the up conversion type)player or HD receiver box has HDCP and your display does not, you're SOL. (I think )

That's correct Mort. The display must have HDCP to work with an HDCP source. A display with HDCP will still work with a source that lacks HDCP.

HDCP isn't just a copy protection, it's an encoding format that requires the display to decode the signal. It's more like compression than copy protection.
