Since the announcement of the setting of this content protection protocol, some have criticized the ascendant compatibility issues with the screens already present on the market since several years.
Indeed, among the HD « compatible » screens, very few are still yet equipped with digital inputs and for those that have a DVI input, most of them do not support HDCP.
The consumers equipped so will then likely have to see the protected medias in a standard definition, if not being displayed a blank screen !
Even worse, numerous manufacturers still continue to produce non HDCP-compliant high definition TV sets without educating theirs consumers on the risk they run.
The same problem occurs for PCs for which very few graphic cards and screens support that protocol at present.
