Why can I not get my Elgato HD60 to work with the Pro? There is sound on the TV and in the Elgato software but the display shows a black screen on both. I have unticked the HDCP box in settings, HDR is turned off and resolution is set to 1080p. It's been bugging me for the last two hours, everything I have tried is a no go. I tried it with the Xbox One S and that works fine, so I am rather puzzled right now!
