ATI has received a lot of bad press in the past for claims of HDCP compliancy when its X1000 series of graphics cards lacked it. This enraged a group of users filed a class action law suit against ATI. NVIDIA was in a much better position as it is a chip manufacturer and doesn’t make its own boards nor was there HDCP compliancy advertised all over product boxes and manufacturer websites.  While ATI and NVIDIA GPUs have support for HDCP, a separate chip that stores decoding keys is required to output a fully HDCP compliant video signal.

Since the whole ordeal of HDCP compliancy started, add-in board manufacturers are beginning to add HDCP decoding keys to products. One of the manufacturers with HDCP compliant cards on display at Computex 2006 is MSI. MSI has two NVIDIA based HDCP compliant cards on display -- a 7900GT and 7600GT. Both cards boast dual DVI output and HDCP compliance but it’s unknown if both DVI outputs can output an HDCP compliant signal or if only one output is compliant.
