Thank you for your help, Remi. As we are using nVidia cards, I have posted this on nVidia forum.

The video output plugin can refuse to output anything. It can also and
alternatively requests scaling down to SD though that would be inefficient;
the GPU is usually far more efficient for video scaling.

HDCP negotiation is a matter for the hardware output, not for VLC. You need to
check which whichever video output and/or audio output API you happen to use,
how HDCP is exposed if at all.
