Using NUC6 with WMC7. the HDMI is playing fine at 4k@30 but when using the CAC-1170 on DP1.2 I get "the video playback device does not support playback of protected content".
It plays backs fine at 4k@60 on desktop or in WMC non-cable card protected content.
Is there firmware upgrade or work around for HDCP?
