             | 
             | I'd have expected HDMI LA to be very very strict in

             | keep up the game? It's not like pirates can already defeat

             | even before HDCP ever enters the field.

         | strip HDCP on the secondary output. You can check reviews for
         | hints.

       | Or unfortunately, for the unlucky people who didn't do their

       | their GPU's PCIe bus.
