Yes, the TMDS encoder may be HDCP compliant, but unless is has the
keys and an HDCP cipher, it doesn't really help...
This is a higher-end ATI card.  And that's the marketing bullet set
which suggest compliancy.

A receiver cannot dictate encryption required.  It is told (via
Encryption Status Signaling) what to do on a per-frame basis.  One
can't enable encryption until link status has been confirmed, yet one
needs an active video signal to start encrypting!
