Multiple BlackMagic Video Cards

Hi,



Running ProTools 11 on a system with two Blackmagic cards installed (duo and 4k extreme). Need to control which card is used by ProTools. The output always defaults to Decklink SD1 on Duo card. I need the Decklink 4k Extreme to be active output due to needing the HDMI out from the Decklink 4k. However every time I start the system and ProTools it goes to the duo card unless I physically remove it from the computer. Is there a way just to deactivate the Decklink Duo without pulling it from the computer?



Thanks,

Todd
